For example, processing for receiving input information for moving body control for controlling the behavior of the moving body OB1 (first object, object to be operated by the player), and shooting for firing bullets (missiles, machine guns) from the moving body OB1 Accept input information. In particular, the receiving unit 110 according to the present embodiment may perform processing for receiving selection of an item (for example, a weapon).

  Further, for example, the receiving unit 110 may receive viewpoint position change input information for changing the position of the virtual camera relative to the moving body to a specific position. Note that the item selection information may be the same as the viewpoint position change input information. That is, when the item selection information is received, the viewpoint position may be simultaneously changed to the viewpoint position corresponding to the item (change from camera control during normal battle to item camera control).

  The accepting unit 110 accepts input information of the first special command when a predetermined condition is satisfied. For example, the accepting unit 110 is a case where the first moving body is tracked by the second moving body, and the distance between the first moving body and the second moving body is within the first predetermined distance. In some cases, it is determined that the predetermined condition is satisfied. Specifically, when the receiving unit 110 tracks the first moving body within the second predetermined distance and the first moving body is being tracked by the second moving body. The predetermined condition may be determined to be satisfied when the distance between the first moving body and the second moving body is narrowed within a first predetermined distance shorter than the second predetermined distance.

  The receiving unit 110 may determine that the predetermined condition is satisfied when the inclination angle of the first moving body with respect to the reference axis in the object space is within a predetermined angle.

  The receiving unit 110 may determine that the predetermined condition is satisfied when the relative speed between the first moving body and the second moving body is within a predetermined speed range.

  Further, the receiving unit 110 may receive the input information of the first special command after the period that satisfies the predetermined condition continues for the first predetermined period.

  In addition, when the second moving body is being tracked by the first moving body, the receiving unit 110 moves the second moving body to a position where the second moving body tracks the first moving body. When the first special command is executed, the input information of the second special command may be received during the second predetermined period from the start of the execution of the first special command.

  For example, when the receiving unit 110 receives input information of the first special command from the first input unit that operates the first moving body, the receiving unit 110 receives the second predetermined command from the time when the first special command is received. You may make it receive a 2nd special command from the 2nd input part which operates a 2nd moving body during a period.

  In addition, when the receiving unit 110 receives (receives) input information of the first special command from the terminal 10A that operates the first moving body, the receiving unit 110 receives the second special command from the time when the first special command is received. During the predetermined period, the second special command may be received (receivable) from the terminal 10B that operates the second moving body.

  The object space setting unit 111 performs processing for arranging an object in an object space (virtual three-dimensional space). For example, the object space setting unit 111 includes a moving object OB1, a moving object OB2 (second object, a moving object that moves and operates based on a computer program, an attacking object, a non-player character NPC, and an object to be operated by another player. In addition, the display object such as a building, a stadium, a car, a tree, a pillar, a wall, and a map (terrain) is arranged in the object space. Here, the object space is a virtual game space, for example, a space in which objects are arranged in three-dimensional coordinates (X, Y, Z) such as a world coordinate system and a virtual camera coordinate system.

  For example, the object space setting unit 111 arranges an object (an object composed of a primitive such as a polygon, a free-form surface, or a subdivision surface) in the world coordinate system. Also, for example, the position and rotation angle (synonymous with direction and direction) of the object in the world coordinate system is determined, and the rotation angle (X, Y, Z axis rotation) is determined at that position (X, Y, Z). Position the object at (Angle).

  The object space setting unit 111 may perform processing for arranging an instruction object such as a special command input instruction object or a marker on a screen (two-dimensional image, screen, screen coordinate system). Further, the object space setting unit may arrange the pointing object in the object space (three-dimensional space, world coordinate system, virtual camera coordinate system, model coordinate system).

  In particular, the object space setting unit 111 sets a predetermined range in the object space. This predetermined range can be a three-dimensional volume including a plurality of enemy objects (enemy ground objects) arranged in the object space.

  The movement / motion processing unit 112 performs a movement / motion calculation of an object in the object space. That is, based on input information received from the input unit 160, a program (movement / motion algorithm), various data (motion data), etc., the object is moved in the object space, or the object is moved (motion, animation).

  The moving body control unit 112a controls the behavior of the moving body in the object space. The behavior of the moving body is movement / operation information of the moving body, and includes at least one of rotation (change of direction) of the moving body and change of the moving direction. Note that the behavior of the moving body may include the speed and acceleration of the moving body. For example, the moving body control unit 112a obtains a rotation angle (orientation) about the X axis, the Y axis, and the Z axis of the model coordinate system of the moving body every frame (for example, 1/60 seconds). Moreover, the mobile body control part 112a performs the process which calculates | requires the moving direction of a mobile body for every frame. Note that a frame is a unit of time for performing object movement / motion processing and image generation processing.

  For example, the mobile body control unit 112a controls the behavior of the first mobile body (for example, the mobile body OB1) based on the input information for mobile body control from the input unit 160, and based on the mobile body control program, You may make it perform the process which controls the behavior of 2 mobile bodies (for example, mobile body OB2).

  In addition, the moving body control unit 112a may perform a bullet movement process so that a bullet (for example, a missile or a cannon) fired from the moving body tracks the target object.

  In addition, when the movement / motion processing unit 112 transmits / receives data to / from other terminals via a network, based on data such as input information received from other terminals and movement information of other aircraft, You may make it control the behavior (movement / movement) of the other mobile body (movable body of the operation target of the player who operates another terminal) arrange | positioned in the object space of this terminal 10A.

  In particular, the moving body control unit 112a of the present embodiment controls the behavior of the moving body in the object space based on the input information for moving body control. For example, the moving body control unit 112a moves the first moving body based on input information for moving body control in the object space.

  In addition, when the moving body control unit 112a of the present embodiment receives the input information of the first special command, the first moving body changes the second moving body regardless of the input information for moving body control. The first moving body is moved to the position to be tracked.

  In addition, when the moving body control unit 112a receives input information of the first special command, the moving body control unit 112a may correct the orientation of the first moving body so as to face the direction of the second moving body. For example, when the input information of the first special command is received, the first moving body moves to the position where the first moving body tracks the second moving body regardless of the input information for controlling the moving body. Then, at the position, the direction of the first moving body may be corrected based on the direction from the first moving body to the second moving body.

  Moreover, the mobile body control part 112a may control the direction of a 1st mobile body so that it may face the direction of a 2nd mobile body, when a 2nd special command is received. Further, when the moving body control unit 112a does not accept the second special command during the second predetermined period, the behavior of the second moving body may be limited.

  The hit determination unit 114 determines whether or not a bullet (for example, a missile) fired from the second moving body hits the first moving body. Further, the hit determination unit 114 determines whether or not a bullet fired from the first object hits the second object.

  The game calculation unit 115 performs various game processes. For example, a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for ending a game when the game end condition is satisfied, and an ending when the final stage is cleared There is processing.

  The game calculation unit 115 determines whether or not a bullet fired from the first moving body hits the second moving body, and a bullet fired from the second moving body hits the first moving body. It is determined whether or not the game is performed, and a game calculation is performed based on each determination result.

  For example, the game calculation unit 115 performs a process of updating the parameters of each object (including the moving object OB1 and the moving object OB2). In the game calculation unit 115 of the present embodiment, the damage accumulation value I in which damage is accumulated is updated every time a bullet hits the moving object OB1. For example, when the damage accumulation value I of the moving object OB1 reaches the maximum value (I = 100), it is considered that the moving object OB1 has shot down, and a process for ending the game is performed. On the other hand, when the damage accumulation value I of all the moving objects OB2 in the game reaches the maximum value, processing for determining that the game is cleared is performed.

  The game calculation unit 115 advances the game based on the game progress speed. For example, when the restriction condition is satisfied (for example, during the movement of the offense and defense maneuver), the game calculation unit 115 may reduce the game progress speed (may be set to slow motion).

  The display control unit 116 performs processing for causing the display unit 190 to display the image generated by the drawing unit 120.

  The virtual camera control unit 117 performs a virtual camera (viewpoint) control process for generating an image that can be seen from a given (arbitrary) viewpoint in the object space. Specifically, when generating a three-dimensional image, the position (X, Y, Z) of the virtual camera in the world coordinate system and the rotation angle (for example, from the positive direction of each axis of the X, Y, and Z axes) (Rotation angle when turning clockwise) is controlled. In short, the virtual camera control unit 117 performs processing for controlling at least one of the viewpoint position, the line-of-sight direction, the angle of view, the moving direction, and the moving speed of the virtual camera.

  In particular, the virtual camera control unit 117 of the present embodiment controls a virtual camera that follows the behavior of the moving object. For example, the virtual camera is controlled based on the first person viewpoint shown in FIGS. 2A and 2B and the third person viewpoint (rear viewpoint) shown in FIG.

  For example, the virtual camera control unit 117 controls the virtual camera based on the behavior (behavior information) of the moving body such as the position, orientation, or speed of the object obtained by the movement / motion processing unit 112. That is, the virtual camera control unit 117 of this embodiment controls a virtual camera that follows the behavior of the moving object. For example, the virtual camera control unit 117 performs control so that the behavior of the moving object processed by the moving object control unit 112a and the behavior of the virtual camera maintain a predetermined relationship in the world coordinates.

  More specifically, in the world coordinates, control is performed so that the position of the moving object (the center point P of the moving object) processed by the moving object control unit 112a and the position (CP) of the virtual camera maintain a predetermined positional relationship. To do. For example, the position of the moving body (central point P of the moving body) and the position (CP) of the virtual camera are controlled so as to maintain a predetermined distance. In addition, control is performed so that the moving direction and moving speed of the moving body and the moving direction and moving speed of the virtual camera maintain a predetermined relationship. For example, the moving direction of the moving body and the moving direction of the virtual camera are controlled to be the same direction, and the moving speed of the moving body and the moving speed of the virtual camera are controlled to be the same speed. In addition, the virtual camera control unit 117 controls the direction (gaze direction) of the virtual camera so that the direction (rotation) of the moving body and the direction (rotation) of the virtual camera maintain a predetermined relationship. For example, the moving body and the virtual camera are controlled so that they face the same direction. Further, the virtual camera control unit 117 controls the rotation direction and the rotation speed of the virtual camera so that the rotation direction and the rotation speed of the moving body maintain a predetermined relationship. For example, control is performed so that the rotation direction and rotation speed of the moving body are the same as the rotation direction and rotation speed of the virtual camera.

  The virtual camera control unit 117 of this embodiment controls a virtual camera that follows the behavior of the first moving body. In addition, when the virtual camera control unit 117 receives input information of the first special command, the first virtual camera information that follows the behavior of the first moving body and the first moving body is the second. You may make it set the 2nd virtual camera information (for example, the virtual camera information which observes the movement route of an offense and defense replacement maneuver) which watches the movement of the 1st moving body until it tracks the said moving body. The second virtual camera information is preliminarily stored as virtual camera information (viewpoint position, line-of-sight direction, movement direction, angle of view, rotation (orientation)) corresponding to the movement route information, and storage unit 170 and information storage medium 180 Or the like.

  In addition, when the virtual camera control unit 117 receives input information of the second special command during the second predetermined period, the virtual camera control unit 117 changes the line-of-sight direction of the virtual camera according to the direction of the first moving body. You may do it.

  In addition, when the virtual camera control unit 117 does not accept the second special command during the second predetermined period, the first moving body and the second moving body are started from the start of the execution of the first special command. Until the tracking relationship is reversed, the line-of-sight direction of the virtual camera may be controlled so as to watch the second moving body.

  The virtual camera control unit 117 may control an overhead virtual camera by arranging an overhead virtual camera that looks down from a given position in the object space.

  In addition, the virtual camera control unit 117 may be used to control a replay virtual camera by arranging a replay virtual camera for generating an image for replay in the object space. The replay virtual camera does not necessarily follow the movement of the moving body, but may control the replay virtual camera according to the movement information of the moving body.

  The communication control unit 118 may perform a process in which a terminal (for example, a first terminal) transmits / receives data to / from another terminal (for example, a second terminal) or the server 20 via a network.

  Note that the terminal according to the present embodiment may perform processing for acquiring and managing network information necessary for communication control from a server. For example, the terminal has a packet associated with terminal identification information (data and ID individually assigned to identify a terminal that can participate in an online game) and terminal identification information that is individually assigned to each terminal. The destination information (IP address or the like) for designating the transmission destination may be acquired and managed.

  The communication control unit 118 generates a packet to be transmitted to another terminal (second terminal) or the server 20, processes to specify the IP address and port number of the packet transmission destination terminal, and data included in the received packet Are stored in the storage unit 170, received packets are analyzed, and other packet transmission / reception control processes are performed.

  In addition, the communication control unit 118 according to the present embodiment stores data until a connection is disconnected after a connection (connection between the first terminal and the second terminal) is established between a plurality of terminals or in the server 20. A process of transmitting and receiving each other at a predetermined cycle (for example, every 1 second) is performed. Here, the data transmitted / received between the terminals may be input information of the input unit, or may be position information and movement information of the operation target object (airframe, moving body) of each terminal.

  In addition, when the communication control unit 118 of the present embodiment receives a packet transmitted from another terminal (second terminal) or the server 20, the communication control unit 118 analyzes the received packet and operates the operation target of the other terminal included in the packet. A process of storing data such as position information of the object in the storage unit is performed.

  In the case of a network system composed of a plurality of terminals, a peer-to-peer (so-called P2P) system that executes an online game while transmitting and receiving data between the plurality of terminals may be used. Each terminal may be based on a client-server system in which an online game is executed while transmitting and receiving data (information). In the network system of the present embodiment, data may be transmitted / received not only by wired communication but also by wireless communication.

  The drawing unit 120 performs drawing processing based on the results of various processes performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. In other words, the drawing unit 120 generates an image that can be seen from the virtual camera in the object space.

  For example, the drawing unit 120 receives object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model). Based on the vertex data included in the object data, vertex processing (shading by a vertex shader) is performed. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary.

  In the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate transformation, for example, world coordinate transformation, visual field transformation (camera coordinate transformation), clipping processing, perspective transformation (projection transformation) ), Geometry processing such as viewport conversion is performed, and based on the processing result, the vertex data given to the vertex group constituting the object is changed (updated or adjusted).

  Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to the image buffer 172 (buffer that can store image information in units of pixels; VRAM, rendering target, frame buffer). . That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated.

  Note that the vertex processing and pixel processing are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

  The drawing unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, the object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the storage unit 170. .

  Texture mapping is a process for mapping a texture (texel value) stored in the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the storage unit 170 using texture coordinates or the like set (given) to the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which Z values (depth information) of drawing pixels are stored. . That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value).

  For example, in α blending, the drawing color (overwriting color) C1 to be drawn in the image buffer 172 and the drawing color (background color) C2 already drawn in the image buffer 172 (rendering target) are set to α values. Based on this, a linear synthesis process is performed. That is, if the final drawing color is C, it can be obtained by C = C1 * α + C2 * (1−α).

  The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  Note that the drawing unit 120 may generate an image including a marker that changes according to the distance between the first moving body and the second moving body. In addition, when the drawing unit 120 satisfies a predetermined condition, an image instructing input of the first special command may be generated.

  In addition, the drawing unit 120 generates an image that can be seen from the virtual camera in the object space. In addition, the drawing unit 120 follows the movement of the operation target object of the terminal (first terminal) when performing a multiplayer online game in which data is transmitted / received to / from another terminal (second terminal) via the network. To generate an image that can be seen from a virtual camera (a virtual camera controlled by a terminal (first terminal)). That is, each terminal performs an independent drawing process.

  When the drawing unit 120 receives input information of the first special command, the first virtual camera information (for example, virtual camera information that follows the behavior of the first moving object) and the second virtual camera You may make it produce | generate an image based on information (for example, virtual camera information which observes the movement path | route of an offense and defense replacement maneuver).

  The sound processing unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates a game sound such as BGM, sound effect, or sound, and outputs the game sound to the sound output unit 192.

  Note that the terminal according to the present embodiment may be controlled so that the game can be played in a single player mode in which only one player can play or in a multiplayer mode in which a plurality of players can play.

  For example, when controlling in the multiplayer mode, game processing may be performed by transmitting / receiving data to / from other terminals via a network. One terminal may perform processing based on input information from a plurality of input units.

2. Outline This embodiment relates to a flight shooting game in which a moving object OB1 to be operated by a player, a moving object OB2 that is a computer object or another player object, and a missile or a cannon attack each other.

  That is, in the present embodiment, the mobile object OB1 and the mobile object OB2 perform a game process in which the other party is a target object (target), and the target object is shot down by firing a missile or a cannon. Therefore, the player who operates the moving object OB1 performs an attack operation so as to hit the moving object OB2 with a missile or a machine gun launched from the moving object OB1, and avoids an attack such as a missile emitted from the moving object OB2. In this way, an operation of moving the moving object OB1 is performed.

  By the way, in such a shooting game, when the mobile object OB2 is attacked using a machine gun, a missile or the like equipped in accordance with the axis of the mobile object OB1, the mobile object OB1 is placed behind the mobile object OB2. It is effective to perform attack operations. On the other hand, if the moving object OB2 is behind the moving object OB1, it becomes easy to receive an attack from the enemy. Therefore, it is effective to perform an operation to escape from the moving object OB2. is there. In other words, when the moving object OB2 is behind the moving object OB1, it is common in conventional games that the player performs an operation of turning the moving object OB1 or turning it to escape. .

  However, when the vehicle is tracked by the moving body OB2, simply performing an operation of escaping does not cause a fight between the moving body OB1 and the moving body OB2, and some shooting games are not interesting.

Therefore, in the present embodiment, as shown in FIG. 3, when the moving object OB1 is being tracked by the moving object OB2, the first player who operates the moving object OB1 performs the first operation when the predetermined condition is satisfied. When the first special command is received, the mobile object OB1 moves to a position where the mobile object OB2 tracks the mobile object OB2 (position where the mobile object OB1 is behind the mobile object OB2). Control is performed to automatically move the body OB1. In this way, it is possible to provide a shooting game capable of performing an incandescent battle in the moving objects OB1 and OB2. Description of the first special command (offense and defense replacement command) In this embodiment, when the input information of the first special command (offense and defense replacement command) is received when a predetermined condition is satisfied, the input information for mobile object control is displayed. Regardless, the first moving body is moved to a position where the first moving body tracks the second moving body.

  For example, as shown in FIG. 3, the moving object OB1 (first moving object) is tracked by the moving object OB2 (second moving object) at time T1, and the moving object OB1 and the moving object are tracked. It is assumed that the distance from OB2 is within the second predetermined distance L2 (for example, within 300 meters).

  In this embodiment, for example, the moving body OB1 decelerates, and the distance between the moving body OB1 and the moving body OB2 is within the first predetermined distance L1 (for example, within 100 meters) shorter than the second predetermined distance. When it is narrowed to a predetermined value, it is determined that the predetermined condition is satisfied.

  For example, when a predetermined condition is satisfied at time T2, the input information of the first special command is received from the input unit of the player who operates the moving object OB1. When the input information of the first special command is received, a process of automatically moving the moving object OB1 is performed based on the prepared travel route information PD1. For example, if the moving object OB2 moves forward during the period in which the moving object OB1 is moving the moving route information PD1, the moving object OB1 can be behind the moving object OB2, and the moving object OB1 is advantageous from a disadvantageous position. It is possible to reverse the offense and defense in the position.

3.1 First special command activation condition (predetermined condition)
Next, in the present embodiment, a predetermined condition that is a condition for activating the first special command will be described. First, in the present embodiment, the close combat mode DFM (dog fight mode, cross-range assault, predetermined mode) is at least one condition for activating the first special command.

3.1.1 Description of close combat mode Here, the close combat mode DFM of this embodiment will be described. In the present embodiment, it is determined whether or not the positional relationship between the moving objects OB1 and OB2 satisfies the close combat mode activation condition. If it is determined that the close combat mode activation condition is satisfied, the close combat mode is activated. The

  As shown in FIG. 4, a conical first determination area A1 and a spherical second determination area B1 are set in the moving object OB1. Similarly, a first determination area A2 having a conical shape and a second determination area B2 having a spherical shape are set in the moving object OB2. The first determination areas A1 and A2 are set so as to extend in front of the aircraft (mobile body OB1 and mobile body OB2), and the second determination areas B1 and B2 are centered in the spherical area behind the aircraft. It is set to be located. Each determination area set in the mobile object OB1 and the mobile object OB2 may have a different set position and shape with respect to the aircraft depending on characteristics (attributes) of the aircraft.

  In the present embodiment, when the moving object OB2 is located in the second determination area B1 of the moving object OB1, and the moving object OB1 is located in the first determination area A2 of the moving object OB2 (the case shown in FIG. 4). ), It is determined that the moving object OB2 is approaching the rear of the moving object OB1, and the “(the moving object OB1 is the escape side, the moving object OB2 is the following side) proximity combat mode” is activated. On the other hand, when the moving object OB1 is located in the second determination area B2 of the moving object OB2 and the moving object OB2 is located in the first determination area A1 of the moving object OB1, the front of the moving object OB1 is located. It is determined that the moving object OB2 is approaching, and the “proximity battle mode (the moving object OB1 follows, the moving object OB2 is the escape side)” is activated.

  In the present embodiment, when the moving object OB1 is located in the second determination area B2 of the moving object OB2 and the moving object OB2 is located in the first determination area A1 of the moving object OB1, the moving object When it is determined that the moving body OB2 is approaching in front of OB1, the input information of the command “(the moving body OB1 follows, the moving body OB2 is the escape side) proximity battle mode” may be received. Good. Then, when the input information of the command “(the moving body OB1 is chasing, the moving body OB2 is the flaming side) proximity battle mode” is received, the “(the moving body OB1 is chasing, the moving body OB2 is the flaming side) The “battle mode” may be activated. It should be noted that “(moving object OB1 follows automatically) when the activation condition is satisfied, regardless of the input information of the command of“ (the moving object OB1 follows, the moving object OB2 escapes) ”proximity combat mode. Side, mobile object OB2 may be on the escape side) close combat mode ".

  In the present embodiment, the moving object OB2 is located in the second determination area B1 of the moving object OB1, and the moving object OB1 is located in the first determination area A2 of the moving object OB2 (FIG. 4). When the input information of the command “(the moving body OB1 is the escape side, the moving body OB2 is the following) close combat mode” is received, “(the mobile body OB1 is the escape side, the mobile body OB2 is the The chasing side) melee combat mode "may be activated. It should be noted that regardless of the input information of the command of “(the moving object OB1 is the escape side, the moving object OB2 is the following) proximity combat mode”, “(the moving object OB1 escapes automatically) when the activation condition is satisfied. Side, the side followed by the moving object OB2) may be activated.

  Here, the positional relationship is determined using the determination area set for the mobile object OB1 and the determination area set for the mobile object OB2, but it is set to either the mobile object OB1 or the mobile object OB2. The positional relationship may be determined using only the determination region.

  Further, when the distance between the moving object OB1 and the moving object OB2 becomes a predetermined value or less, it may be determined that the close combat mode activation condition is satisfied. Further, when the moving object OB1 and the moving object OB2 enter a predetermined range (special area) set in the object space, it may be determined that the close combat mode activation condition is satisfied. Further, when a predetermined operation input is performed by the player or when a predetermined game item is used, it may be determined that the close combat mode activation condition is satisfied.

  In the present embodiment, the moving body OB1 tracks the moving body OB2. In the “tracking side of the moving body OB1, the moving body OB2 is the escape side proximity battle mode”, the moving body is based on the past movement trajectory of the moving body OB2. Follow-up control for causing OB1 to follow the moving object OB2 is performed. In addition, in the case of the proximity combat mode in which the moving object OB1 is tracked by the moving object OB2 and “the moving object OB1 is on the escape side and the moving object OB2 is on the side”, the moving object OB2 is moved based on the past movement locus of the moving object OB1. Follow-up control for following the body OB1 is performed.

  For example, when the moving object OB2 tracks the moving object OB1 in the “proximity battle mode” of this embodiment, the position of the moving object OB2 is obtained by tracing (tracing) the past movement locus of OB1. For example, the position of the mobile object OB2 in the Nth frame is obtained based on the position of the mobile object OB1 in the past (N-Mth frame (for example, M = 30)).

  That is, based on the position of the moving object OB1 in the NM frame, the distance L between the moving object OB1 and the moving object OB2 is more than the first predetermined distance L1 (100 meters) and the second predetermined distance. The position of the moving object OB2 is obtained so that it is within L2 (for example, 300 meters) (L1 <L ≦ L2).

  For example, if the distance L between the position G1 of the Nth frame moving object OB1 and the position G2 of the NMth frame moving object OB1 is not L1 <L ≦ L2, for example, a line connecting G1 and G2 A given position satisfying L1 <L ≦ L2 may be set as the position of the mobile object OB2 in the Nth frame. The same process may be performed when the position of the moving object OB1 when the moving object OB1 tracks the moving object OB2 is obtained in the “proximity battle mode”.

3.1.2 Distance Condition In the present embodiment, when the moving object OB1 is tracked by the moving object OB2, the “proximity battle mode” is set (the moving object OB1 is the escape side and the moving object OB2 is the following side). When the distance L between the moving body OB1 and the moving body OB2 is within the first predetermined distance L1 (L ≦ L1 <L2), it is determined that the predetermined condition is satisfied. On the other hand, when the distance L between the moving body OB1 and the moving body OB2 is larger than the first predetermined distance L1 (L1 <L), it is determined that the predetermined condition is not satisfied.

  That is, when the close combat mode is activated, the mobile body OB2 is controlled so that the distance L between the mobile bodies OB1 and OB2 is larger than the first predetermined distance L1 (L1 <L). ing. Therefore, in this embodiment, the player who operates the moving object OB1 is forced to perform an operation of decelerating the moving object OB1 in order to obtain an opportunity to input the first special command. In short, in the present embodiment, the player who operates the moving object OB1 is given a risk of deliberately decelerating the moving object OB1 so as to be easily attacked by the moving object OB2, and then can have an opportunity to change the offense and defense. I have to. For this reason, in the present embodiment, it is possible to provide a shooting game in which the moving objects OB1 and OB2 are incandescent and capable of fighting.

3.1.3 Aircraft Inclination Conditions In this embodiment, the moving object OB1 is tracked by the moving object OB2 (the moving combat object OB1 is the escape side, the moving object OB2 is the tracking side). In this case, (1) when the distance L between the moving object OB1 and the moving object OB2 is within the first predetermined distance L1 (L ≦ L1), (2) the reference axis (world in the object space (world coordinate system)) When the tilt angle of the moving body OB1 with respect to the coordinate system XZ plane is within a predetermined angle, it is determined that the predetermined condition is satisfied.

  For example, as shown in FIG. 5A, it is assumed that the inclination angle of the moving object OB1 with respect to the reference axis D1 (axis parallel to the world coordinate system XZ plane) is 0 degree. For example, as shown in FIGS. 5B and 5C, for example, the moving body OB1 behaves as a roll, and the inclination angle θ of the moving body OB1 with respect to the reference axis D1 is within a predetermined angle (for example, a predetermined angle) If it is 135 degrees, it is determined that the predetermined condition is satisfied. On the other hand, for example, when the moving body OB1 performs a roll behavior and the inclination angle θ of the moving body OB1 exceeds a predetermined angle with respect to the reference axis D1, it is determined that the predetermined condition is not satisfied.

  Further, as shown in FIG. 6A, it is assumed that the inclination angle of the moving object OB1 with respect to the reference axis D2 (axis parallel to the world coordinate system XZ plane) is 0 degree. For example, as shown in FIGS. 6B and 6C, for example, the moving body OB1 performs a pitch-up and pitch-down behavior, and the inclination angle θ of the moving body OB1 with respect to the reference axis D2 is within a predetermined angle (for example, If the predetermined angle is 135 degrees), it is determined that the predetermined condition is satisfied. On the other hand, for example, when the moving object OB1 performs a pitch-up and pitch-down behavior and the inclination angle θ of the moving object OB1 exceeds a predetermined angle with respect to the reference axis D2, it is determined that the predetermined condition is not satisfied.

  The predetermined angle with respect to the roll behavior of the moving body OB1 may be different from the predetermined angle with respect to the pitch up and pitch down of the moving body OB1.

  In other words, in the present embodiment, when the moving object OB1 being chased is in a special flight state such as a back flight, or when the moving object OB1 is tilted to turn away from the moving object OB2, 1 special command is controlled so that it cannot be executed. In other words, in this embodiment, the player who operates the mobile object OB1 gives a risk of easily receiving an attack from the mobile object OB2 in order to obtain an opportunity to input the first special command. So that you can get. For this reason, in the present embodiment, it is possible to provide a shooting game in which the moving objects OB1 and OB2 are incandescent and capable of fighting.

  In the present embodiment, when the moving object OB1 is tracked by the moving object OB2, and in the “proximity battle mode (the moving object OB1 is the escape side, the moving object OB2 is the following side)”, the moving object OB1 and the moving object OB2 are present. May not be within the first predetermined distance L1 (L ≦ L1). In such a case, the player who operates the moving body OB1 may be stressed.

  Therefore, in the present embodiment, when the moving object OB1 is tracked by the moving object OB2, and in the “proximity battle mode (the moving object OB1 is the escape side, the moving object OB2 is the following side)”, the moving object OB1 and the moving object OB2 are present. If the distance L is longer than the first predetermined distance L1 (L1 <L <L2) and the time period is maintained for a limited period (for example, 10 seconds) or longer, the moving object OB1 and the moving object OB2 When the distance L is within the third predetermined distance L3 (for example, within 200 meters), it may be determined that the predetermined condition is satisfied. Note that the third predetermined distance is shorter than the second predetermined distance and longer than the first predetermined distance (L1 <L3 <L2). In this way, a game environment free from stress can be provided to the player.

3.1.4 Relative Speed Conditions In the present embodiment, it may be determined that the predetermined condition is satisfied when the relative speed between the moving body OB1 and the moving body OB2 is within a predetermined speed range.

  In other words, in the present embodiment, in the case of “the close combat mode in which the moving object OB1 is tracked by the moving object OB2 (the moving object OB1 is the escape side, the moving object OB2 is the following side)” (1) the moving object OB1 When the distance L to the moving object OB2 is within the first predetermined distance L1 (L ≦ L1), (2) with respect to a reference axis (an axis parallel to the world coordinate system XZ plane) in the object space (world coordinate system) When the inclination angle of the moving body OB1 is within a predetermined angle, (3) it may be determined that the predetermined condition is satisfied when the relative speed between the moving body OB1 and the moving body OB2 is within a predetermined speed range.

  For example, assume that the predetermined speed range is set to 0 km / h to 200 km / h. Then, in the present embodiment, for example, when the relative speed between the moving body OB1 and the moving body OB2 is 100 kilometers per hour, it is determined that the predetermined condition is satisfied. On the other hand, the relative speed between the moving body OB1 and the moving body OB2 is determined. When the speed is 300 km / h, it is determined that the predetermined condition is not satisfied.

  As described above, since one condition for satisfying the predetermined condition is that the relative speed between the moving object OB1 and the moving object OB2 is within the predetermined speed range, the positional relationship between the moving object OB1 and the moving object OB2 is appropriate. Thus, the mobile object OB1 can be given an opportunity to attack.

3.1.5 Conditions for collision determination Further, in the present embodiment, the moving body is moved after a specific period (for example, after 5 seconds) from the present time based on at least one of the inclination angle and the moving speed (speed) of the moving body OB1. A process of predicting whether or not OB1 collides (hits) with the ground or an obstacle is performed, and when it is determined that the mobile object OB1 will collide with the ground or an obstacle after a specific period from the present time, a predetermined condition is set. On the other hand, when it is determined that the moving object OB1 does not collide with the ground or an obstacle after a specific period from the present time, it may be determined that the predetermined condition is satisfied.

  In other words, in the present embodiment, in the case of “the close combat mode in which the moving object OB1 is tracked by the moving object OB2 (the moving object OB1 is the escape side, the moving object OB2 is the following side)” (1) the moving object OB1 When the distance L to the moving object OB2 is within the first predetermined distance L1 (L ≦ L1), (2) with respect to a reference axis (an axis parallel to the world coordinate system XZ plane) in the object space (world coordinate system) When the tilt angle of the moving object OB1 is within a predetermined angle, (3) When the relative speed between the moving object OB1 and the moving object OB2 is within a predetermined speed range, (4) After a specific period from the present time, the moving object OB1 When it is determined that the vehicle will not collide with the ground or an obstacle, it may be determined that the predetermined condition is satisfied. In this way, it is possible to avoid a situation where the moving object OB1 collides with the ground or an obstacle.

3.1.6 First Special Command Acceptance Period Further, in the present embodiment, control is performed so that input information of the first special command is accepted after a period satisfying the predetermined condition continues for the first predetermined period K1. .

  For example, as shown in FIG. 7, the “close proximity battle mode” in which the moving object OB1 is tracked by the moving object OB2 from the time point T10 is activated (the moving object OB1 is the escape side and the moving object OB2 is the following side). Then, from time T11, (1) when the distance L between the moving object OB1 and the moving object OB2 is within the first predetermined distance L1 (L ≦ L1), (2) the reference in the object space (world coordinate system) When the tilt angle of the moving object OB1 with respect to the axis (axis parallel to the world coordinate system XZ plane) is within a predetermined angle, (3) When the relative speed between the moving object OB1 and the moving object OB2 is within a predetermined speed range, (4) When it is determined that the moving object OB1 will not collide with the ground or an obstacle after a specific period from the present time, it is determined that the predetermined condition is satisfied.

  In the present embodiment, the input information of the first special command is not accepted during the period from the time when the predetermined condition is satisfied for the first time until the time when the first predetermined period K1 elapses (period T11 to T12). Control is performed so that input information of the first special command is received after the period satisfying the condition continues for the first predetermined period K1. For example, in the example of FIG. 7, the input information of the first special command is received from time T12. Then, after time T12, the input information of the first special command is accepted as long as the predetermined condition is satisfied.

  Therefore, in the present embodiment, during the period of the first predetermined period K1, the moving object OB1 is likely to be attacked by the enemy moving object OB2, and there is a risk. However, after the time point T12, the input of the first special command is accepted, and the opportunity to change the offense and defense of the mobile objects OB1 and OB2 comes. In this way, in the present embodiment, it is possible to create a situation in which the moving object OB1 must take a risk, and thus a more heated battle can be realized. In the present embodiment, the first predetermined period K1 may be variable.

  In the present embodiment, the first predetermined period K1 may not be set. That is, in the present embodiment, control may be performed so that input information of the first special command is always accepted during a period in which it is determined that the predetermined condition is satisfied.

3.1.7 Others In the present embodiment, even when not in close combat mode DFM, (1) the condition that the distance L between the moving object OB1 and the moving object OB2 is within the first predetermined distance L1 (L ≦ L1) (2) A condition that the inclination angle of the moving object OB1 with respect to a reference axis (an axis parallel to the world coordinate system XZ plane) in the object space (world coordinate system) is within a predetermined angle, and (3) the moving object OB1 and the moving object OB2 When the relative speed of the vehicle is within a predetermined speed range, and (4) when at least one of the conditions in which the mobile object OB1 is predicted not to collide with the ground or an obstacle after a specific period from the present time is satisfied. It may be determined that a predetermined condition for invoking the first special command is satisfied. In the present embodiment, the first special command is accepted in a period that satisfies at least one of the conditions (1), (2), (3), and (4) regardless of the first predetermined period K1. You may do it. Further, the reception period of the first special command may be limited to, for example, a predetermined period (for example, 3 seconds).

  In the present embodiment, the moving object OB1 is tracked by the moving object OB2, and the specific condition is satisfied from the time when the activation condition of “the proximity combat mode (the moving object OB1 is the escape side, the moving object OB2 is the following side)” is satisfied. After a period (for example, 3 seconds) has elapsed, it may be determined whether or not a predetermined condition is satisfied.

3.2 First Special Command (Offense / Defense Replacement Command) Execution Processing Next, the first special command execution processing will be described. In this embodiment, when a special command is received, a process for determining any one of a plurality of types of maneuvers (quick loop, barrel roll, cobra, qubit, etc.) maneuvers is performed. Specifically, when receiving the input information of the first special command, the input information for selecting the offense / defense replacement maneuver is received, and the offense / defense replacement maneuver is determined based on the received selected input information. In addition, maneuver indicates a special flight and is a way of moving a moving body such as a fighter aircraft in the air. For example, there are various ways of moving such as a quick loop, a barrel roll, a cobra, a qubit, etc. In this embodiment, since the moving body is moved in accordance with the maneuver trajectory, a game that attracts the player can be realized.

  For example, as shown in FIG. 8, the offense / defense replacement maneuver is associated with the input information “right”, “left”, “up”, and “down” of the direction key. For example, when the input information of the direction key “right” is received simultaneously with the input information of the first special command, as shown in FIG. 3, the moving object OB1 in the object space is based on the moving route information PD1 of the quick loop. Behavior (movement information such as position, orientation, movement direction, movement speed) is calculated, and the moving object OB1 is moved based on the calculated behavior.

  The travel route information PD1 is a predefined motion (animation) stored in the storage unit 170, and is travel information such as position, orientation, and travel speed. In the present embodiment, the moving route information PD1 is subjected to coordinate conversion or the like in the coordinate system of the object space, and the moving object OB1 is moved.

  Further, during the period in which the moving object OB1 is moving according to the moving route information PD1, the enemy mobile object OB2 ends the close combat mode with the moving object OB1, and the follow-up function is released. When the moving object OB2 is a non-player character controlled by a computer program, the moving object OB2 may be controlled to go straight as shown in FIG.

  Further, during the period in which the moving object OB1 is moving, the moving object OB2 may be moved without going straight. For example, when the moving object OB2 is controlled based on the input information for moving object control of another player, as shown in FIG. 9A, the moving object is executed by executing a special command at time T20. While the OB1 is moving based on the movement route information of the offense and defense maneuver, the moving object OB2 may escape. For example, at the end of the movement of the offense and defense replacement maneuver of the moving object OB1 (at time T21), if the direction V2 of the moving object OB2 is different from the direction V1 of the moving object OB1, it becomes difficult for the moving object OB1 to attack.

  Therefore, in the present embodiment, the direction V1 of the moving object OB1 is corrected so as to face the direction of the moving object OB2 at the end of the movement of the offense / defense replacement maneuver of the moving object OB1 (at time T21). For example, the direction from the position P1 of the moving body OB1 to the position Q1 of the moving body OB2 may be set as the direction V1 of the moving body OB1. Further, the direction of the moving body OB1 may be set so that the direction V1 of the moving body OB1 is parallel to the direction V2 of the moving body OB2.

  In the present embodiment, as shown in FIG. 3, the tracking relationship between the moving object OB1 and the moving object OB2 is reversed. If the trigger condition of “(the moving body OB1 follows, the moving body OB2 escapes) proximity combat mode” is satisfied, the “(the moving body OB1 follows, the moving object OB2 escapes) the proximity combat mode” Activate.

  In addition, as shown in FIG. 3, if the moving object OB1 escapes by taking the first special command and conversely takes behind the moving object OB2, the situation is advantageous for the moving object OB2. Regardless, the attack on mobile OB1 has failed. In the present embodiment, the behavior of the moving object OB2 is limited to the moving object OB2 for a predetermined time limit as a penalty.

  That is, in the “proximity battle mode” (the moving object OB1 is the escape side and the moving object OB2 is the pursuit side), when the mobile object OB1 escapes and the close combat mode is released, the roll is a rotation around the axis of the mobile object OB2. The rotation speed is reduced, and the rotation angle is limited to a predetermined angle (for example, 10 degrees). Moreover, the change angle per unit time of the ascending angle (pitch up), descending angle (pitch down), and yaw (changing the moving direction while keeping the moving body horizontal) of the moving body OB2 is limited. In this way, as at time T4 in FIG. 3, the moving object OB1 behind the moving object OB2 can easily attack the moving object OB2.

3.3 Image Generation Processing 3.3.1 Image Generation Processing in Close Combat Mode Next, image generation processing according to the present embodiment will be described. FIGS. 10A, 10B, and 10C are examples of images displayed on the terminal 10 that operates the moving object OB1 in the “(the moving object OB1 is the escape side, the moving object OB2 is the following side) proximity combat mode”. It is.

  For example, as shown in FIG. 10A, in the close combat mode in which the moving object OB1 is on the escape side and the moving object OB2 is on the side, the marker MK for the moving object OB1 is displayed. Then, as shown in FIG. 10B, when the position of the moving object OB1 (for example, the position of the center point or the representative point of the moving object OB1) falls within the display range of the marker MK, Gauge GA is displayed. The gauge GA is displayed so that the value thereof increases as time elapses when the moving object OB1 is located in the marker MK, and is reset when the moving object OB1 is no longer located in the marker MK (the value of the gauge GA). Becomes 0). Note that the value of the gauge GA may be decreased by a predetermined value when the moving object OB1 is no longer positioned within the marker MK. Further, the value of the gauge GA may be decreased with the passage of time when the moving object OB1 is not located in the marker MK.

  As shown in FIG. 10C, when the time for which the moving body OB1 is located in the marker MK reaches a predetermined time (for example, 0.5 seconds) and the value of the gauge GA reaches the maximum value, the moving body OB1 moves. A lock-on state is established in which the body OB2 is locked on. When this lock-on state is established, a guided missile (special weapon) having a higher guidance performance than a normal guided missile is fired from the mobile body OB2, and the launched missile will land on the mobile body OB1 with high probability. .

  The player who operates the moving object OB1 can visually grasp how the moving object OB1 is aimed at the guide missile of the moving object OB2 by the marker MK for the moving object OB1, and is displayed on the marker MK. By using the gauge GA, it is possible to visually grasp the timing when the lock-on state is established.

  The player who operates the moving object OB1 performs an operation of moving the moving object OB1 so that the moving object OB1 does not enter the marker MK, or when the moving object OB1 is included in the marker MK, By performing an operation of moving the moving object OB1 out of the marker MK until the gauge GA of the marker MK reaches the maximum value (before entering the lock-on state), a guided missile with high guiding performance is launched from the moving object OB2. The situation can be avoided.

  In the present embodiment, an image including the marker MK that changes according to the distance between the moving object OB1 and the moving object OB2 is generated. That is, the closer the distance between the moving body OB1 and the moving body OB2, the larger the size (radius) of the marker MK, and the easier it is for the moving body OB1 to be targeted from the moving body OB2 (it is difficult to avoid the marker MK). On the other hand, as the distance between the moving object OB1 and the moving object OB2 increases, the size (radius) of the marker MK decreases, and the moving object OB1 is less likely to be targeted from the moving object OB2 (the marker MK can be easily avoided).

  In addition, the player who operates the moving object OB1, for example, increases the distance between the moving object OB1 and the moving object OB2 by performing an operation such as accelerating the moving object OB1, thereby reducing the size of the marker MK. It is possible to avoid a situation where a guided missile with high guidance performance is launched from OB2.

3.3.2 Image generation process instructing input of first special command FIG. 11 shows a case where a predetermined condition is satisfied in “(the moving object OB1 is on the escape side, the moving object OB2 is on the following side) close combat mode”. 6 is an example of an image instructing input of a first special command (an image displayed on the terminal 10 operating the moving object OB1). In the present embodiment, the input information of the A button is the input information of the first special command, and when the input information of the A button is received, the first special command is executed.

  Therefore, in the present embodiment, during the special command reception period (during the period from T12 to T13 in FIG. 7), as shown in FIG. 11, the input instruction mark for the first special command “A” is displayed at the center of the image. An image including MS1 (first instruction image MS1) is generated. Therefore, the player who operates the moving object OB1 can surely know that the moving object OB1 has a risk that the moving object OB2 is locked on, and that the first special command can be input. it can.

3.3.3 Image of Offense / Defense Replacement Maneuver In the present embodiment, a virtual camera that follows the behavior of the moving object OB1 is controlled to generate an image that can be seen from the virtual camera for the moving object OB1 in the object space. That is, an image that can be seen from the virtual camera for the moving object OB1 is generated on the display unit of the terminal 10 that controls the moving object OB1.

  Here, in the present embodiment, when the input information of the first special command is received and the virtual camera control unit 117 of the terminal 10 generates an image for the moving object OB1, the following is performed. Perform image generation processing. That is, the movement path of the offense and defense maneuver based on the first virtual camera information CD0 following the behavior of the moving object OB1 and the moving route information PD1 of the moving object OB1 until the moving object OB1 tracks the moving object OB2 is observed. When the second virtual camera information is set and the input information of the first special command is received, an image is generated based on the first virtual camera information CD0 and the second virtual camera information. To do. Note that the virtual camera information includes at least one piece of information of viewpoint position, line-of-sight direction, moving direction, angle of view, and rotation (orientation).

  For example, as shown in FIG. 12A, the virtual camera C that follows the moving object OB1 at time T30 generates an image based on the virtual camera information CD0.

  Then, at time T31, the first special command input information is received. For example, when the input information of the quick loop offense and defense maneuver in FIG. 8 is received, the movement route information PD1 and the virtual camera information CD1 corresponding to the input information are received. (Example of second virtual camera information) is read from the storage unit 170 (or the information storage medium 180).

  In this embodiment, the moving object OB1 is controlled to move based on the moving route information PD1, and an image including the moving object OB1 is generated based on the virtual camera information CD1 during movement by the “quick loop”. .

  For example, as shown in FIG. 12A, when input information of the first special command is received, the first virtual camera information CD0 and the second virtual camera information CD1 are synthesized (for example, linear synthesis). Then, the process proceeds to the second virtual camera information CD1.

  Thereafter, based on the second virtual camera information CD1, an image for gazing at the movement path of the offense and defense replacement maneuver of the moving object OB1 is generated. Then, as shown in FIG. 12B, the first virtual camera information CD1 and the first virtual camera information CD0 are synthesized (for example, linearly synthesized) immediately before the end of the offense and defense maneuver, while the first virtual camera information CD0 is synthesized. Transition to virtual camera information CD0. Then, at the time T34 when the movement of the offense / defense replacement maneuver of the moving object OB1 is completed, the virtual camera information CD0 is shifted to generate an image.

  It is to be noted that the second virtual camera information CD1 is used to calculate the virtual camera information CD0 following the behavior of the moving object OB1 and to watch the moving path of the offense-defense maneuver of the moving object OB1 until the moving object OB1 tracks the moving object OB2. These operations may be processed in parallel.

  That is, in the present embodiment, the movement route information PD1 corresponding to the offense / defense replacement maneuver stored in the storage unit 170 and the virtual camera information CD1 corresponding to the selected offense / defense replacement maneuver are reproduced. When starting playback of the virtual camera information CD1, when the first special command is received, the virtual camera information CD1 that follows the behavior of the moving object OB1 is transferred to the virtual camera information CD1. The virtual camera information CD0 and CD1 are reproduced while being synthesized. Further, when the reproduction of the virtual camera information CD1 is finished, the virtual camera information CD0 is shifted to the virtual camera information CD0 that follows the behavior of the moving object OB1 while synthesizing the virtual camera information CD0 and CD1. In this way, a seamless camera effect can be performed.

  Note that the virtual camera information is switched from CD0 to CD1 at the start of playback of the virtual camera information CD1 without combining the virtual camera information CD0 and CD1, and the virtual camera information is switched from CD1 to CD0 at the end of playback. Good.

  Further, the game progress speed may be reduced (slow motion) during the period in which the moving object OB1 is moving along the movement path of the offense and defense maneuver. In this way, the player can carefully check the state of the special flight of the moving object OB1 and the state in which the tracking relationship is reversed.

3.4 Process Flow Finally, the process flow until the first special command is executed will be described. First, it is determined whether or not the close combat mode has been activated on the side where the moving body OB1 escapes and the side where the moving body OB2 follows. When the escape side proximity battle mode is not activated, N in Step S1 repeats Step S1. On the other hand, in the case of Y in step S1 where the escape side proximity battle mode is activated, it is determined whether or not a predetermined condition is satisfied. For example, it is determined whether or not the distance between the escape-side moving body OB1 and the following-side moving body OB2 is within a predetermined distance, and the inclination of the moving body OB1 is within a predetermined angle (step S2). .

  If the predetermined condition is not satisfied (N in Step S2), Step S2 is repeated. On the other hand, if the predetermined condition is satisfied (Y in step S2), it is determined whether or not the first predetermined period K1 has elapsed (step S3).

  When the first predetermined period K1 has elapsed (Y in step S3), it is determined whether or not a first special command offense / defense replacement command has been received (step S4). When the first special command offense / defense replacement command is received (Y in step S4), the first special command (offense / defense replacement command) is executed (step S5). The process ends here.

3.5 Explanation in the case where a plurality of moving bodies are tracked In this embodiment, when the moving body OB1 is tracked by a plurality of moving bodies OB2 and OB3, “moving body OB1” and “movement Whether or not the activation condition (predetermined condition) of the first special command is satisfied is determined based on the relationship with the moving object OB2 that is closest to the object OB1.

4). Explanation of Second Special Command (Enemy Tracking Command) In the present embodiment, the first special command (offense and defense) that satisfies the predetermined condition in the “proximity battle mode in which (mobile object OB1 follows, mobile object OB2 escapes)”. When the replacement command is executed, the tracking relationship between the mobile objects OB1 and OB2 is reversed, and the mobile object OB1 may be chased.

  For example, when the moving object OB2 is a non-player character NPC controlled by a computer program, the first special command is executed by the computer program when the predetermined condition is satisfied, and the moving object OB2 is behind the moving object OB1. It is controlled to take. Further, the mobile unit OB1 is controlled based on the input information from the first input unit or the first terminal 10A, and the mobile unit OB2 is controlled based on the input information from the second input unit or the second terminal 10B. In such an interpersonal battle, the mobile OB2 may be behind the mobile OB1 by executing the input information of the first special command from the second input unit or the second terminal 10B. .

  In the present embodiment, as shown in FIG. 14, the first special command (offense and defense replacement command) that satisfies the predetermined condition in the “(the moving body OB1 chasing side, the moving body OB2 is the escape side) proximity combat mode” at time T40. ) Is executed. Then, as shown at time T41, even if the tracking relationship between the mobile objects OB1 and OB2 is likely to be reversed, the mobile object OB2 is executed by executing the second special command (enemy tracking command). Gives the mobile body OB1 an opportunity to prevent the mobile body OB1 from being taken behind.

  That is, the second special command (enemy tracking command) is a command for controlling the direction of the moving object OB1 so as to face the direction of the enemy moving object OB2, regardless of the input information for moving object control. Therefore, as shown at time T42 in FIG. 14, if the second special command is surely input, the moving object OB1 automatically faces in the direction of the enemy moving object OB2, so that the player who operates the moving object OB1. Can easily shoot down the enemy aircraft OB2 simply by performing a shooting input of a machine gun or missile. As described above, in the present embodiment, the mobile object OB1 is given an opportunity to attack before the enemy aircraft OB2 is behind, so that a more heated battle game can be played.

4.1 Conditions for Activating Second Special Command (Enemy Tracking Command) Next, conditions for activating the second special command will be described in the present embodiment. First, in the present embodiment, when the moving object OB2 is tracked by the moving object OB1, and the distance between the moving object OB1 and the moving object OB2 is within the first predetermined distance L1, a given Executing the first special command for moving the moving object OB2 to the position where the moving object OB2 tracks the moving object OB1 at the timing is an activation condition.

  In the present embodiment, the input information of the second special command can be received during the second predetermined period K2 from the start of execution of the first special command. For example, as shown in FIG. 15, when the execution of the first special command is started at time T51, the second predetermined period K2 is set as the second special command reception period from time T51. As described above, in the present embodiment, the second special command input is accepted only during the start period of the offense / defense replacement maneuver, so that the player who operates the mobile object OB1 has the opportunity to attack the mobile object OB1. It is important not to miss the input timing of the second special command.

  Note that the second predetermined period K2 may be fixed or variable. For example, in the online mode (a mode in which game processing is performed by transmitting / receiving data to / from a plurality of terminals 10 or the server 20 via a network), when input information of the first special command is received from the counterpart terminal due to the influence of communication lag Tend to be delayed.

  Therefore, in the online mode, the second predetermined period K2 is set to 0.5 seconds, and the offline mode (single player mode, multiplayer mode in which one terminal performs processing based on input information from a plurality of input units). In the online mode, the second predetermined period K2 may be set shorter than that in the offline mode by setting the second predetermined period K2 to 1 second.

4.2 Execution Processing of Second Special Command (Enemy Tracking Command) In this embodiment, as shown in FIG. 15, when input information of the second special command is received in the second predetermined period K2, The direction of the moving object OB1 is controlled so as to face the direction of the moving object OB2 that is an enemy aircraft (that is, control is performed so as to perform enemy tracking). That is, the direction of the moving object OB1 is controlled so as to face the direction of the moving object OB2 which is an enemy aircraft, regardless of the input information for moving object control. For example, as shown at time T41 in FIG. 14, the direction V1 of the moving object OB1 is set in the direction connecting the position P1 of the moving object OB1 and the position Q1 of the moving object OB2.

  Then, as shown at T54 in FIG. 15, the player who operates the moving object OB1 inputs an attack command to attack the moving object OB2 and prevent the behavior of performing offense and defense replacement of the moving object OB2. it can. For example, a machine gun is fired from the moving object OB1 based on the shooting input information. For example, if the fired bullet hits the moving object OB2, the moving object OB2 will fail to take offense and defense. In addition, you may make it make the attack power at the time of tracking enemy aircraft with a 2nd special command larger than the time of a normal battle.

  As shown in FIG. 16, when the player operating the moving object OB1 does not input the second special command in the second predetermined period K2 of the second special command, The direction of the moving object OB1 is not controlled so as to face the direction of the moving object OB2 which is an enemy aircraft. Therefore, the moving body OB1 needs to perform an operation to escape so as not to be tracked. The moving body OB2 succeeds in the offense / defense replacement that takes behind the moving body OB1.

  In addition, as shown in FIG. 17, even if the player operating the moving object OB1 inputs the second special command during the second predetermined period K2 of the second special command, the moving object OB1 moves. When the body OB2 is not attacked, the offense and defense replacement of the mobile body OB2 is successful, and the mobile body OB1 is behind the mobile body OB2. Accordingly, the moving object OB1 inputs the second special command during the second predetermined period K2, and after the direction of the moving object OB1 is controlled to face the direction of the moving object OB2, the shooting input information Based on the above, a bullet is fired from the moving object OB1.

  As shown in FIGS. 16 and 17, when the input information of the second special command is not received during the second predetermined period, the behavior of the first moving body is limited for a predetermined time limit. . That is, even if the moving object OB1 is in an advantageous position for tracking the moving object OB2, if the advantageous position cannot be fully utilized, the behavior of the moving object OB1 is limited as a penalty.

  The restriction of the behavior of the moving object OB1 is, for example, a process of reducing the rotation speed related to the roll, which is rotation around the axis of the moving object OB1, and a process of limiting the rotation angle to a predetermined angle (for example, 10 degrees). In addition, the change angle per unit time of the moving body OB1 may be limited, such as the rising angle (pitch up), the descending angle (pitch down), and yaw (changing the moving direction while keeping the moving body horizontal). Further, the moving speed of the moving object OB1 may be limited (eg, cannot be accelerated).

  In this way, it is possible to create a situation where the mobile object OB1 is more likely to be hit when the mobile object OB1 is tracked by the mobile object OB2, and a game capable of more intense battle can be provided.

4.3 Virtual Camera Control 4.3.1 Image Generation Processing in Close Combat Mode Next, image generation processing according to the present embodiment will be described. FIGS. 18A and 18B are examples of images displayed on the terminal 10 that operates the moving object OB1 in the "(the moving object OB1 is chasing, the moving object OB2 is the escape side) proximity combat mode".

  For example, as shown in FIG. 18A, when the close combat mode is activated, a marker MK is displayed. For example, when the position of the moving object OB2 enters the display range of the marker MK, the gauge GA is displayed on the inner peripheral side of the marker MK. The gauge GA is displayed so that the value thereof increases as time elapses when the moving object OB2 is located in the marker MK, and is reset when the moving object OB2 is no longer located in the marker MK (the value of the gauge GA). Becomes 0). Note that the value of the gauge GA may be decreased by a predetermined value when the moving object OB2 is no longer positioned within the marker MK. In addition, the value of the gauge GA may be decreased as time elapses when the moving body OB2 is not located in the marker MK.

  As shown in FIG. 18A, when the time for which the moving object OB2 is located in the marker MK reaches a predetermined time (for example, 0.5 seconds) and the value of the gauge GA reaches the maximum value, the moving object OB2 moves. A lock-on state is established in which the body OB1 is locked on. In this lock-on state, a guided missile (special weapon) having higher guidance performance than a normal guided missile is fired from the moving object OB1, and the launched guided missile will land on the moving object OB2 with high probability. .

  In the present embodiment, an image including the marker MK that changes according to the distance between the moving object OB1 and the moving object OB2 is generated. That is, the closer the distance between the moving body OB1 and the moving body OB2, the larger the size (radius) of the marker MK, and the easier it is for the moving body OB2 to be targeted from the moving body OB1 (it is difficult to avoid the marker MK). On the other hand, as the distance between the moving object OB1 and the moving object OB2 increases, the size (radius) of the marker MK decreases, and the moving object OB2 becomes difficult to be targeted from the moving object OB1 (the marker MK is easily avoided).

4.3.2 Image Generation Processing for Instructing Input of Second Special Command FIG. 18B shows the second in the “proximity battle mode in which the moving object OB1 follows and the moving object OB2 escapes”. This is an example of an image instructing the input of the second special command (an image displayed on the terminal 10 operating the mobile object OB1) when the activation condition of the special command is satisfied. In the present embodiment, the input information of the B button is used as the input information of the second special command, and when the input information of the B button is received, the second special command is executed.

  Therefore, in the present embodiment, in the second predetermined period K2 for receiving the special command (during the period from T51 to T53 in FIG. 15), as shown in FIG. An image including the input instruction mark MS2 (first instruction image MS2) of the second special command is generated. Therefore, the player who operates the moving object OB1 can surely know that the second special command can be input.

4.3.3 Description of image generation process when second special command is executed or not executed In this embodiment, an image that can be seen from a virtual camera that follows the behavior of the moving object OB1 is generated. When input information of the second special command is received during the predetermined period K2, control is performed to change the line-of-sight direction of the virtual camera in accordance with the direction of the moving object OB1.

  FIG. 19 is a diagram for describing the control of the virtual camera C when the second special command is received during the second predetermined period. For example, as shown in FIG. 19, an image is generated based on the virtual camera information CD0 of the virtual camera C that follows the moving object OB1 at time T80.

  Then, when the first special command is executed, the moving object OB2 starts to move by the quick loop offense and defense maneuver. For example, when the second special command is received at time T81 during the second predetermined period, the direction V1 of the moving object OB1 is set in the direction of the moving object OB2. The line-of-sight direction CV of the virtual camera C is also set to the same direction as the moving body direction V1. For example, when the moving object OB1 performs a shooting attack on the moving object OB2 at time T82, a powerful image at the time of shooting can be generated.

  FIG. 20 is a diagram for explaining the control of the virtual camera C when the second special command is not received during the second predetermined period. As shown in FIG. 20, an image is generated based on the virtual camera information CD0 of the virtual camera C that follows the moving object OB1 at time T90.

  Then, when the first special command is executed, the moving object OB2 starts to move by the quick loop offense and defense maneuver. In the present embodiment, when the second special command is not received during the second predetermined period, the line-of-sight direction of the virtual camera C is controlled so as to watch the moving object OB2, as shown in T91. For example, the line-of-sight direction of the virtual camera C is controlled so that the moving object OB2 is watched until the tracking relationship between the moving object OB1 and the moving object OB2 is reversed after the first special command execution is started. After the tracking relationship between the moving object OB1 and the moving object OB2 is reversed, the line-of-sight direction of the virtual camera may follow the direction of the moving object OB1.

  FIG. 21 is a diagram for explaining the control of the virtual camera C when the second special command is received during the second predetermined period but the shooting attack fails. For example, as shown in FIG. 21, an image is generated based on the virtual camera information CD0 of the virtual camera C that follows the moving object OB1 at time T100.

  Then, when the first special command is executed, the moving object OB2 starts to move by the quick loop offense and defense maneuver. For example, when a second special command is received at time T101 during the second predetermined period, the direction V1 of the moving object OB1 is set in the direction of the moving object OB2. The line-of-sight direction CV of the virtual camera C is also set to the same direction as the moving body direction V1.

  However, after the moving object OB1 does not perform a shooting attack on the moving object OB2 and the tracking relationship between the moving object OB1 and the moving object OB2 is reversed as in the time point T102, the line-of-sight direction of the virtual camera is changed to the moving object. Follow the direction of OB1.

  Whether or not the tracking relationship between the moving objects OB1 and OB2 is reversed is determined based on the positional relationship between the moving objects OB1 and OB2. For example, when the position of the moving object OB2 is located behind the position of the moving object OB1 in the traveling direction of the moving object OB1, it may be determined that the tracking relationship between the moving object OB1 and the moving object OB2 is reversed.

  Also, after the attack of the moving object OB1 is completed (or after the movement of the offense and defense replacement maneuver of the moving object OB2 is completed), the control is switched to the original virtual camera control that follows the behavior of the moving object OB1. When switching the virtual camera control, the first virtual camera information that follows the behavior of the moving object OB1 and the second virtual camera information from the start to the end of the offense and defense change maneuver (the end of the attack) are calculated in parallel. Also good. The start period of the offense / defense change maneuver is a combination of the first virtual camera information and the second virtual camera information (for example, linear combination) to shift to the second virtual camera information, and the end period of the offense / defense change maneuver. In the (attack end period of the moving object OB2), the first virtual camera information and the second virtual camera information may be combined (for example, linearly combined) to shift to the first virtual camera information. In this way, seamless camera control can be performed. As described above, in this embodiment, an unprecedented camera effect can be performed.

4.4 Process Flow Finally, the process flow until the second special command is executed will be described with reference to FIG. First, it is determined whether or not the chasing side proximity battle mode (the moving body OB1 is chasing, the moving body OB2 is the escape side) is activated (S10). If the chasing side proximity battle mode is not activated, N in step S10 repeats step S10. On the other hand, in the case of Y in step S10 when the chasing side proximity battle mode is activated, it is determined whether or not the first special command (offense and defense replacement command) has been executed (step S11).

  If the first special command is not executed (N in step S11), step S11 is repeated. On the other hand, when the first special command is executed (Y in step S11), the input information of the second special command (enemy tracking command) is obtained during the second predetermined period K2 from the time of execution of the first special command. It is determined whether it has been accepted (step S12).

  When input information of the second special command (enemy tracking command) is received during the second predetermined period K2 from the time of execution of the first special command (Y in step S12), the second special command (enemy tracking command) ) Is executed (step S13), and the process is terminated.

  On the other hand, when the input information of the second special command (enemy tracking command) is not received during the second predetermined period K2 from the time of execution of the first special command (N in step S12), the process is terminated.

4.5 Others In this embodiment, when the non-player character NPC is the moving object OB2, and the moving object OB1 and the moving object NPC battle each other, the advance notice of the first special command is executed. For this purpose, a notice process may be executed. Then, the second predetermined period K2 may be set based on the execution time of the advance notice process.

  That is, in the present embodiment, when the moving object NPC is tracked by the moving object OB1, and the distance between the moving object OB1 and the moving object NPC is within the first predetermined distance L1, the time point is T50. The notice process is executed, and then the first special command is executed at time T51. In such a case, in the present embodiment, the input information of the second special command may be received during the second predetermined period K2 from the time T50 when the notice process is executed. In this way, since the input information of the second special command is received before the first special command is actually executed, the player who operates the mobile object OB1 has a margin for the second special command. Input operation can be performed.

5. 5. Explanation of communication control 5.1 Online game processing example 1

In the infrastructure mode, the Internet Inet (public communication network) can be accessed via the access point ACSP1 or ASCP2. Each of the terminals 10A to 10C can transmit / receive a packet including game information or firmware update information to / from the server 20 connected to the Internet Inet via the access point ACSP1 or ACSP2.

  In the network system of this embodiment, the mobile object OB1 of the terminal 10A may perform a game calculation that attacks the mobile object OB2 of another terminal 10B. In the network system of the present embodiment, the first group constituted by the operation target mobile bodies OB1 and OB2 of the plurality of terminals 10A and 10B, and the operation target mobile body OB3 of each of the plurality of terminals 10C and 10D. , A game calculation may be performed in which the second group configured by OB4 plays a battle.

  Further, in the present embodiment, each terminal is connected to another machine (a mobile object to be operated by a player who operates another terminal) arranged in the object space of the terminal based on data such as movement information via the network. ) Is moved and operated. That is, each terminal 10 transmits data including behavior (direction, moving direction, position, moving speed) of the moving object, input information for moving object control, input information for shooting, and the first special command via the network. Data such as the input information of the second special command is transmitted and received.

  For example, at the drawing frame rate (for example, every 1/60 seconds), the terminal 10A transmits the position P of the operation target body OB1 of the terminal 10A to the terminal 10B. On the other hand, the terminal 10B transmits the position Q of the machine OB2 to be operated by the terminal 10B to the terminal 10A at the drawing frame rate, similarly to the terminal 10A.

  In addition, each terminal performs processing for generating an image that can be seen from the virtual camera in the object space of each terminal as a game image. Therefore, an image corresponding to the behavior of the moving body operated by the terminal is generated for each terminal.

5.2 Online game processing example 2
In this embodiment, the present invention may be applied to a client-server online game.

Note that the moving object OB2 may be a non-player character NPC or a moving object controlled based on input information for moving object control from another terminal 10B. Further, the server 20 performs mobile body control for moving the mobile body OB1 based on the input information for mobile body control received from the terminal 10A in the object space.

  The server 20 satisfies the predetermined condition when the moving object OB1 is tracked by the moving object OB2 and the distance between the moving object OB1 and the moving object OB2 is within the first predetermined distance. If the predetermined condition is satisfied, a process for receiving input information of the first special command is performed. For example, when the input information of the first special command is received from the terminal 10A, a process of receiving the input information of the first special command is performed. Then, when the server 20 receives the input information of the first special command, the mobile object OB1 does not depend on the input information for controlling the mobile object from the terminal 10A, but the mobile object OB1 follows the mobile object OB2. OB1 is moved.

  That is, similarly to the terminal 10 described above, the server 20 determines whether or not the trigger condition for the first special command is satisfied. If the trigger condition for the first special command is satisfied, the server 20 determines the first special command. Execute. Similarly to the terminal 10 described above, the server 20 determines whether or not the trigger condition for the second special command is satisfied, and if the trigger condition for the second special command is satisfied, the server 20 determines the second special command. You may make it perform.
