Further, when the attack determination unit 114 determines that the player character has successfully attacked the enemy character, the communication control unit 116 moves the enemy character with respect to another game device. Send data to identify.

  In addition, when the role of the own device in the multiplayer game is a child device, the communication control unit 116 starts request data for requesting the start of the second game mode when the mode transition condition is satisfied. May be transmitted to the parent device. Then, when the communication control unit 116 receives the start notification data for notifying the start of the second game mode transmitted from the parent machine in response to the start request data, the mode setting unit 115 2 game mode is started.

  The virtual camera control unit 118 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, based on operation data or a program (movement / motion algorithm) input by the player through the operation unit 160, the position (X, Y, Z) or rotation angle (for example, X of the virtual camera in the world coordinate system). , Y, and Z axes, the rotation angle when rotating clockwise as viewed from the positive direction is performed. In short, processing for controlling the viewpoint position, the line-of-sight direction, and the angle of view is performed.

  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. When generating a so-called three-dimensional image, first, 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 is input. Based on the vertex data included in the input 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, projective transformation (perspective transformation) , Projection conversion), viewport conversion (screen coordinate conversion), light source calculation, and other geometric processing are performed, and based on the processing results, the vertex data given to the vertex group constituting the object is changed (updated, adjusted). To do. Object data after the geometry processing (position coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) is stored in the object data storage unit 176.

  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 a drawing buffer 174 (a buffer capable of storing image information in units of pixels; VRAM). 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.

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

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit 178 of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit 178 of the storage unit 170 using the texture coordinates set (given) at 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 by a Z buffer method (depth comparison method, Z test) using a Z buffer 179 (depth buffer) in which a Z value (depth information) of a drawing pixel is stored may be performed. it can. That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer 179 is referred to. Then, the Z value of the referenced Z buffer 179 is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is the front side when viewed from the virtual camera (for example, a small Z value). If it is, the drawing process of the drawing pixel is performed and the Z value of the Z buffer 179 is updated to a new Z value.

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

2. Next, the method of this embodiment will be described with reference to the drawings.

2-1. Outline In the game device of this embodiment, a multiplayer game can be played by communicating with three other game devices via a network. When starting a game, any one of the game devices becomes a parent device, and the other game devices become child devices. The game device that becomes the parent device performs a participation process in the game based on the request for participation in the game transmitted from the game device that becomes the child device, and each game device has the mutual IP address, MAC address, and player information. Acquire and exchange character information.

  In each game device, the character is moved and moved in the object space based on operation data from the operation unit and movement information and motion information received from another game device, and an image of the object space viewed from the virtual camera is generated, It is displayed on the display unit as a game image. In the game image, a player character corresponding to the player of the player, three friendly characters corresponding to the respective players of the three other game devices, and a plurality of enemy characters that are non-player characters (NPCs) are displayed. Is done. The player of each game device can play a game in which the player character moves and moves to fight the enemy character in cooperation with the teammate character. If there are less than four game devices participating in the game, an ally character that is an NPC is displayed. Further, the movement / motion process of the teammate character that is the NPC is performed by the game device that is the parent machine.

2-2. Transition of Game Mode In the game according to the present embodiment, the player character and the teammate character attack each enemy character one after another in the first game mode in which the player character and the teammate character individually fight with a plurality of enemy characters. There is a second game mode. Then, in the first game mode, when a predetermined mode transition condition is satisfied, the mode shifts to the second game mode. In the present embodiment, in the first game mode, when a player character or an ally character attacks an enemy character, the physical strength value of the enemy character is equal to or lower than a predetermined value (the attack for satisfying the mode transition condition is successful). In the case), the mode transition condition is determined to be satisfied, and the second game mode in which the enemy character is the target of the continuous attack is started. Note that when there is a special operation input (for example, an operation input for simultaneously pressing two predetermined buttons on the operation unit) in any of the game devices, it may be determined that the mode transition condition is satisfied. When the enemy character enters a predetermined state (for example, an inoperable state), it is determined that the mode transition condition is satisfied, and the second game mode in which the enemy character is the target of continuous attack is started. May be. In addition, a predetermined game parameter (stan value) that increases each time an attack is received is set in the enemy character, and the enemy character that is in a predetermined state (stan state) when this stun value becomes equal to or greater than a predetermined value. When a special attack (attack performed by a special operation input) is performed, the second game mode in which the enemy character is a target of continuous attack may be started.

  FIG. 2 is a diagram illustrating a time chart when the second game mode is started. As shown in FIG. 2, when it is determined that the mode transition condition is satisfied by the attack on the enemy character by the character corresponding to the player of the game device that is the child device, the child device starts the second game mode. Start request data for requesting is transmitted to the game device which is the parent device. Here, the start request data includes a player ID for specifying the slave player (or character) that transmitted the start request data, and an enemy character ID for specifying the enemy character that is the target of the continuous attack. It is.

  The parent machine enters the second game mode when receiving the start request data from the child machine or when it is determined that the mode transition condition is satisfied by an attack on the enemy character by the player character of the own machine (parent machine). The start notification data for notifying the preparation for the transition is transmitted to all the slave units, and the second game mode start process (preparation process) is performed. Here, in the start notification data, a player ID for specifying a player (slave player that transmitted start request data or a master player) that succeeded in an attack for satisfying the mode transition condition, and a continuous ID An enemy character ID for specifying an enemy character to be attacked is included. The start notification data also includes counter information that counts in synchronization among a plurality of game devices. When each slave unit receives a plurality of start request data at the same time, it can identify the start request data transmitted first from the base unit based on this counter information.

  When receiving the start notification data, the slave unit starts the second game mode and transmits start notification response data notifying that the start notification data has been received to the master unit. Here, as the start process of the second game mode, the process of fading out the game image of the first game mode, the player character, the ally character, and the enemy character that is the target of the continuous attack are used for the second game mode. Is placed in the object space. When the start processing is completed, each game device (master device and slave device) transmits preparation completion notification data for notifying that the start processing is completed to all game devices. When the master unit receives the preparation completion notification data from all the slave units, or when the waiting time of the preparation completion notification data times out, all the start notification data for notifying the start of the second game mode It transmits with respect to a subunit | mobile_unit, and a 2nd game mode is started. When the child device receives the start notification data, the child device transmits start notification response data notifying that the start notification data has been received to the parent device, and starts the second game mode.

  Thus, the start request data for requesting the start of the second game mode is transmitted to the parent device, and the parent device causes all the child devices to start the second game mode in accordance with the start request data. By doing so, it is possible to avoid processing confusion when a plurality of game devices simultaneously request the start of the second game mode.

2-3. Second Game Mode FIG. 3 is a diagram for describing the second game mode. In the second game mode, the player character, the teammate character, and the enemy character are arranged in an object space different from the object space in the first game mode. In the second game mode, it is possible to continuously attack the enemy character while moving the enemy character between the player character and the teammate character tactor.

  In this embodiment, as shown in FIG. 3A, the player character PC and the teammate characters AC1, AC2, and AC3 are each positioned at one of the four vertices of the square in the object space of the second game mode. Are arranged as follows. FIG. 3A is a diagram showing an example of the arrangement state of each character at the start of the second game mode. Here, the enemy character EC that is the target of the continuous attack satisfies the mode transition condition. It is located in the vicinity of the teammate character AC1 corresponding to the player of another game device that has successfully attacked. Then, as shown in FIG. 3B, the enemy character EC moves toward the player character PC located in front of the teammate character AC1.

  At this time, the player of the game apparatus can cause the player character PC to attack the enemy character by operating the operation unit. If the attack is successful, the enemy character EC is removed from the ally character AC1 that is the movement source. It can be moved toward one of the characters AC2 and AC3. Here, whether or not the attack is successful is determined based on the input timing to the operation unit and the processing result of the hit check processing of the attack of the player character PC and the enemy character. That is, an attacking operation is performed within a time period (within a predetermined time) until the enemy character EC reaches the position of the player character, and the enemy character EC is set in the hit area HA set in the player character PC at the time of the operation. If so, it is determined that the attack was successful. In addition, when an operation for an attack is not performed within the predetermined time, or when the enemy character EC is not located in the hit area HA at the time of the operation, it is determined that the attack has failed. The hit area HA is set in a size and shape corresponding to the character type and attributes (for example, game parameters such as attack power, experience value, and possessed items).

  When the enemy character EC moves toward the player character PC, the player of the game apparatus operates the operation unit at a timing when the enemy character EC is sufficiently close to the player character PC while viewing the game image. By successfully attacking the enemy character EC, the enemy character EC can be moved toward the teammate character.

  Further, in this embodiment, when it is determined that the attack is successful, it is determined to which friendly character the enemy character EC is moved based on the operation data input to the operation unit. For example, among the four buttons 162 (see FIG. 3E) provided in the operation unit, when the right “◯” button is pressed as an operation for an attack, it is shown in FIG. Thus, the enemy character EC moves toward the teammate character AC2 located on the right side from the player character PC, and when the left “□” button is pressed as an operation for attack, the enemy character EC Moves toward the teammate character AC3 located on the left side from the player character PC.

  Here, when it is determined that the attack by the player character PC is successful, the game device transmits attack success notification data notifying that the attack has been successful to all other game devices. The attack success notification data includes a player ID for specifying the player of the game device that transmitted the attack success notification data, a character ID for specifying a friend character to which the enemy character EC is moved, and an attack hit. Includes the position coordinates of the enemy character EC. In another game device that has received the attack success notification data, the enemy character EC can be moved from the position at the time of the hit toward the character specified by the character ID.

  In addition, when the game device receives the attack success notification data from another game device, the game device moves the enemy character EC from the position at the time of the hit toward the character (a friend character or the player character PC) specified by the character ID. Let For example, as shown in FIG. 3C, when the enemy character EC moves toward the teammate character AC2, the attack success notification data is received from another game device (the game device of the player corresponding to the teammate character AC2). If the character specified by the character ID included in the successful attack data is the teammate character AC3, as shown in FIG. 3D, the enemy character EC is directed from the position at the time of the hit toward the teammate character AC3. Move. In this way, the game device player cooperates with the other game device players to perform a game play in which the enemy character EC is continuously attacked while moving the enemy character EC between the player character PC and the teammate characters AC1 to AC3. I can enjoy it.

  In addition, when it is determined that the attack by the player character PC has failed, the game device transmits attack failure notification data notifying that the attack has failed to all other game devices. When it is determined that the attack by the player character PC has failed, or when the attack failure notification data is received from another game device, the game device performs a game effect when the attack has failed, Exit game mode.

  Further, when the game device determines that the predetermined end condition is satisfied, the game device transmits attack end notification data for notifying that the continuous attack is ended to all other game devices. For example, when the player of the game device presses the “x” button among the four buttons BT shown in FIG. 3E at the time of attack and the attack is successful, the end condition is satisfied (the last condition in the continuous attack). It is determined that the attack was successful. Here, when all the characters participating in the second game mode (player character PC and allied characters AC1 to AC3) each successfully attack one or more times, it is possible to input the “x” button. It may be made to become. Further, the attack with the “x” button may cause more damage to the enemy character EC than the attack with the other buttons. Further, based on the total number of times that the player character PC and the teammate characters AC1 to AC3 attack the enemy character EC (the number of consecutive attacks) before the “×” button is input, the “x” button attacks. May be determined (the amount of damage to the enemy character EC by the attack).

  Further, when the number of times that the player character PC and the teammate characters AC1 to AC3 attack the enemy character EC has reached a predetermined number, it may be determined that the end condition is satisfied. When the game device determines that the end condition is satisfied, or receives attack end notification data from another game device, the game device performs a game effect when the attack ends and ends the second game mode. To do.

  In the present embodiment, the speed at which the enemy character EC is moved between the player character PC and the teammate characters AC1 to AC3 is determined based on the number of times that the player character PC and the teammate characters AC1 to AC3 have attacked the enemy character EC continuously. Has been decided. Here, as the number of consecutive attacks increases, the speed of the enemy character EC at the time of movement increases, and the time from when the enemy character EC is attacked by a character to the position of another character is shortened. I have to. Each player must perform an attacking operation within the time (movement time) from when the enemy character EC is attacked by a character corresponding to another player until the enemy character EC reaches the position of its own character. If it does in this way, when the continuous attack with respect to enemy character EC continues for a long time, the difficulty of operation for attack can be raised.

  Further, in the second game mode, as shown in FIG. 3B, the virtual camera VC is set behind the player character PC, and the line-of-sight direction (or gazing point) faces the moving enemy character EC. To be controlled. In addition, if the direction of the line of sight of the virtual camera VC is always directed toward the enemy character EC, the game image changes abruptly when the moving speed of the enemy character EC becomes extremely large. In addition, when the moving speed of the enemy character EC exceeds a predetermined speed, the line-of-sight direction of the virtual camera VC may be fixed, or the line-of-sight direction may be changed gently. For example, the line-of-sight direction GV1 that faces the enemy character and the line-of-sight direction GV2 that faces the center point that is equidistant from the player character PC and the teammate characters AC1 to AC3 are combined to obtain a new line-of-sight direction GV3. May be set as the line-of-sight direction of the virtual camera VC, and the composition ratio of the line-of-sight direction GV2 may be increased as the moving speed of the enemy character EC increases.

3. Processing Next, an example of processing of the game device of the present embodiment will be described with reference to the flowchart of FIG. Here, an example of processing in the second game mode will be described.

  First, it is determined whether or not attack success notification data has been received from another game device (step S10). If it is determined that it has been received, the count value of the number of consecutive attacks on the enemy character EC is only 1. Increase (step S11).

  Next, it is determined whether or not the character (movement destination character) specified by the character ID included in the received successful attack notification data is the player character PC (step S12). If it is determined that the character is not the player character PC, the moving speed of the enemy character EC is obtained based on the count value of the number of times the enemy character has been attacked continuously, and the enemy character EC is specified as the character ID with the obtained moving speed. Move toward the teammate character (step S14), and proceed to step S10.

  If it is determined in step S12 that the destination character is the player character PC, the moving speed of the enemy character EC is obtained based on the count value of the number of times the enemy character has been attacked continuously, and the obtained moving speed is obtained. Based on the above, the moving distance for one frame is obtained, and the enemy character EC is moved toward the player character PC by the obtained moving distance (step S16). Prior to the movement of the enemy character EC, the movement time of the enemy character (the time from when the enemy character EC is attacked by the teammate character until reaching the position of the player character PC) is obtained based on the movement speed of the enemy character EC. Start counting travel time.

  Next, it is determined whether or not there is an operation input for an attack (step S18). If it is determined that there is no operation input, it is determined whether or not the movement time has elapsed (step S20). If it is determined that it is not, the process proceeds to step S16.

  If it is determined in step S18 that there has been an operation input for an attack, based on the position of the enemy character EC and the hit area set for the player character PC, the attack of the player character PC is the enemy character EC. Is determined (step S22), and if it is determined that it has been hit, it is determined whether or not a predetermined end condition is satisfied (step S24), and it is determined that it is not satisfied. In this case, a friend character to which the enemy character EC is moved is determined based on the input operation data (step S26).

  Next, the successful attack notification data including the character ID for specifying the determined teammate character and the position coordinates of the enemy character EC at the time of the hit is transmitted to another game device (step S28), and the enemy character EC. The count value of the number of times of attacking continuously is increased by 1. Next, the moving speed of the enemy character EC is obtained based on the count value of the number of times the enemy character has been attacked continuously, and the enemy character EC is moved toward the determined ally character at the obtained moving speed (step S30).

  When it is determined that the travel time has elapsed in the process of step S20, and when it is determined that the attack has not been hit in the process of step S22, attack failure notification data is transmitted to another game device. (Step S32), the game effect is performed and the second game mode is ended (Step S34).

  If it is determined in step S24 that the end condition is satisfied, attack end notification data is transmitted to another game device (step S36), and the process proceeds to step S34.

  If it is determined in step S10 that the attack success notification data has not been received, it is determined whether attack failure notification data or attack end notification data has been received from another game device ( Step S38) If it is determined that any data has been received, the process proceeds to Step S34.
