It includes 117, a drawing unit 120, and a sound processing unit 130. It should be noted that a configuration in which some of these may be omitted may be used.

The standing position selection unit 110 performs a process of determining whether the basic standing position of the player's character in the game image is on the right side or the left side of the basic standing position of the opponent's character based on the player's selection instruction. .. Specifically, when the opponent has entered the battle game and the opponent has been decided, the display unit 190 displays a selection screen for accepting selection instructions such as "RIGHT" and "LEFT" as shown in FIG. , The player is made to input right and left selection by operating the lever 32. The input selection instruction data is stored in the selection instruction data storage unit 174 of the storage unit 170 as the selection instruction data 174a of the own machine. In addition, the selection instruction data transmitted from the opponent is also stored as the selection instruction data 174b of the opponent. The basic standing position in the present embodiment means the initial standing position.

The game calculation unit 115 executes a process related to the progress of the fighting game. For example, the process of starting the game when the game start condition is met, the process of advancing the game, the process of ending the game when the game end condition is met, and the process of advancing the ending when the final stage is cleared. There is processing and so on.

The object space setting unit 111 performs a process of arranging an object in an object space (virtual three-dimensional space). For example, a process of forming a game space (for example, a stage for a character to engage in a fight) is performed in a virtual three-dimensional virtual space. In addition to characters, display objects such as buildings, stadiums, cars, trees, pillars, walls, and maps (terrain) are placed 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 primitives such as polygons, free-form surfaces, and subdivision surfaces) in the world coordinate system. Also, for example, the position and rotation angle (synonymous with direction and direction) of an object in the world coordinate system are determined, and the rotation angle (X, Y, Z axis) is rotated at that position (X, Y, Z). Place the object by angle).

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

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

The character control unit 112a controls the behavior of a character object (character), which is a main object, in the object space. Specifically, a process of controlling the operation of the character of the own machine and the opponent based on the operation code based on the operation input to the operation unit 160, the operation code acquired from the game machine 10 of the opponent, and the data of the selection instruction. , Performs processing to display an effect when a specific condition is met, processing to determine a hit of an attack technique, and processing to damage it.

The character control unit 112a performs such processing every frame (for example, 1/60 second). A frame is a unit of time for performing object movement / motion processing and image generation processing.

The operation code transmission / reception control unit 113 transmits an operation code indicating which input device of the operation unit 160 has been operated to the other device via the communication control unit 114 and the communication unit 196 for a predetermined cycle (for example, a time for performing an image generation process). (Period equal to or shorter than the unit of) is transmitted, and the process of receiving the operation code sent from the remote device is executed.

The input operation code data is stored in the operation code data storage unit 176 of the storage unit 170 as the operation code data 176a of the own machine. In addition, the operation code data transmitted from the opponent is also stored as the operation code data 176b of the opponent.

Further, the operation code transmission / reception control unit 113 also executes a process of transmitting the selection instruction data 174a of the own machine stored in the selection instruction data storage unit 174 to the other device prior to the start of the game.

The display control unit 116 performs a process of displaying the image generated by the drawing unit 120 on the display unit 190.

The virtual camera control unit 117 performs control processing of the virtual camera (viewpoint) 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, Z axis) Performs a process to control the rotation angle) when turning clockwise. In short, the virtual camera control unit 117 performs a process of 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 a character object (character).

The first and second virtual cameras 300A and 300B are arranged so as to be symmetrical with respect to the reference point M, the reference line L10, or the reference plane S determined by the position P2, and the first and second virtual cameras 300A are arranged so as to be symmetrical. The first and second virtual cameras 300A and 300B are controlled so that the positions of the 300Bs are point-symmetrical, line-symmetrical or plane-symmetrical. At this time, the directions of the first and second virtual cameras 300A and 300B are controlled so that the line-of-sight directions of the first and second virtual cameras 300A and 300B face the reference point M, and the first and second virtual cameras to compete with each other are controlled. The imaging range 400 of the first and second virtual cameras 300A and 300B is controlled so that the two characters OB1 and OB2 face left and right.

For example, the game machine 10 associates the terminal identification information (data individually given to identify the terminals that can participate in the online game, ID) individually given to each game machine with the terminal identification information. The process of acquiring and managing the destination information (IP address, etc.) that specifies the destination of the received packet may be performed.

The communication control unit 114 stores in the storage unit 170 a process of generating a packet to be transmitted to another terminal or a server, a process of designating an IP address or a port number of the packet transmission destination terminal, and data included in the received packet.

Processes for transmitting and receiving to each other in a cycle (for example, in a cycle of 1 second).

In the case of a network system composed of a plurality of terminals, a peer-to-peer (so-called P2P) method of executing an online game while transmitting / receiving data between the plurality of terminals may be used, or via a server 2. It may be a client-server system in which each terminal executes an online game while transmitting and receiving data (information). Further, in the network system of the present embodiment, data may be transmitted and received not only by wired communication but also by wireless communication.

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

For example, the drawing unit 120 is input with object data (model data) including vertex data (position coordinates of vertices, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model). Vertex processing (shading by the vertex shader) is performed based on the vertex data included in the created object data. When performing the vertex processing, the vertex generation processing (tessellation, curved surface division, polygon division) for subdividing the polygon may be performed as necessary.

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

Then, rasterization (scanning conversion) is performed based on the vertex data after the vertex processing, and the faces of the polygons (primitives) are associated with the pixels. Then, following the rasterization, pixel processing (shading by a pixel shader, fragment processing) for drawing the pixels (fragments constituting the display screen) constituting the image is performed. In pixel processing, various processing such as texture reading (texture mapping), color data setting / change, translucent composition, antialiasing, etc. is performed according to the pixel processing program (pixel shader program, second shader program) to create an image. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-converted object is output (drawn) to the image buffer 172 (a buffer that can store image information in pixel units. VRAM, rendering target, frame buffer). .. That is, in the pixel processing, per pixel processing is performed in which image information (color, normal, brightness, α value, etc.) is set or changed in pixel units. As a result, an image that can be seen from a virtual camera (given viewpoint) in the object space is generated.

Note that vertex processing and pixel processing are realized by hardware that enables programmable polygon (primitive) drawing processing by a shader program written in a shading language, so-called programmable shaders (vertice shaders and pixel shaders). With programmable shaders, processing in units of vertices and processing in units of pixels can be programmed, which gives a high degree of freedom in drawing processing content, and greatly improves expressiveness compared to fixed drawing processing using conventional hardware. Can be done.

Then, when drawing the object, the drawing unit 120 performs geometry processing, texture mapping, hidden surface erasing processing, α blending, and the like.

In the geometry processing, processing such as coordinate transformation, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, the object data (position coordinates of the vertices of the object, 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. ..

The 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 the texture coordinates or the like set (assigned) to the vertices of the object. Then, the texture, which is a two-dimensional image, is mapped to the object. In this case, processing for associating pixels with texels and bilinear interpolation as texel interpolation are performed.

As the hidden surface erasing process, a hidden surface erasing process can be performed by the Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which the Z value (depth information) of drawing pixels is stored. .. That is, when drawing the drawing pixel corresponding to the primitive of the object, 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 of the primitive drawing pixel, and the Z value of the drawing pixel is the Z value (for example, a small Z value) that is on the front side when viewed from the virtual camera. If there is, 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, etc.) based on an α value (A value).

4. Method of this embodiment Next, the method of this embodiment will be described.

(Selection command)
The game machine 10 of the present embodiment determines whether the basic standing position of the player's character on the game screen is on the right side or the left side of the basic standing position of the opponent's character based on the player's selection instruction. The configuration is adopted.

The selection instruction of the player of the own machine is stored in the selection instruction data storage unit 174 as the selection instruction data 174a of the own machine, and is further transmitted to another game machine to be played against. Further, the selection instruction data selected by the player of the other game machine is received from the other game machine to be played against, and is stored in the selection instruction data storage unit 174 as the selection instruction data 174b of the opponent.

Then, on the display 20 of each of the competing game machines 10, any of the first and second virtual cameras 300A and 300B corresponding to the basic standing position determined by the selection instruction of the player of the own machine is photographed. The image of the object space is displayed as a game image.

As a result, each player who competes can arbitrarily set the basic standing position of the character OB1 of his / her own machine to either the right side or the left side and display it as a game screen. You can enjoy fighting games.

(Operation code data)
Further, the game machine 10 of the present embodiment has an input signal from the operation unit 30, specifically, an input signal from the lever 32 that commands the movement of the character OB back and forth and left and right, and from the buttons 34, 36, and 38. Is written in the operation code data storage unit 176 as the operation code data 176a of the own machine every predetermined cycle (for example, 1/60 second), and is transmitted to another game machine as an opponent. Similarly, the operation code data 176b of the other game machine transmitted from the other game machine to be played against is written and stored in the operation code data storage unit 176 at predetermined cycles.

In the present embodiment, as described above, in each game machine 10, the player can select the basic standing position of his / her character OB1 to either the right or the left of the game screen. Therefore, when the basic standing position of the player character OB is selected on the right side of the screen and on the left side, for example, the direction input instruction in the left-right direction of the lever 32 is opposite.

Therefore, in the game machine 10 of the present embodiment, the character control unit 112a gives a direction input instruction included in the operation code data 176a and 176b of the own machine and another machine, particularly a direction input instruction in the left-right direction. Selection instruction data 174a of another machine. Based on 174b, it is converted into directional data in the world coordinate system of the object space and interpreted, and each character OB1 and OB2 is controlled.

As a result, each player who competes can operate his / her character without discomfort while looking at the game screen.

(Control of virtual camera)
Further, in the game machine 10 of the present embodiment, the first and second virtual cameras are point-symmetrical, line-symmetrical, or plane-symmetrical with respect to the reference point M, the reference line L10, or the reference plane S in the object space. Controls 300A and 300B. In particular, in the present embodiment, the first and second virtual cameras 300A and 300B are set to any one of the point symmetry control mode, the line symmetry control mode, and the plane symmetry control mode according to the progress of the game. Control is performed by appropriately selecting the mode.

By switching the control mode of the virtual camera in this way, it is possible to provide a game image having a high effect as the game progresses.

5. Flow Chart of Processing Next, an example of processing of the game system of the present embodiment will be described with reference to the flowchart of FIG. 11 (steps S10 to 20).

First, when the player applies for a fighting game using the game machine 10 of the present embodiment (step S10), an application signal is transmitted to the game server 2 via the network N, and the game server 2 receives the game. Another game machine 10 to be an opponent of the machine 10 is determined, and a notification to that effect is given to both game machines 10 to be opposed (step S12).

At this time, the game server 2 may transmit an ID or the like that identifies both game machines 10 to be played against to both game machines 10, or both game machines 10 to be played may exchange IDs.

When the opponent is determined in this way, as shown in FIG. 9, on the game screen of each game machine 10, each player is allowed to select the basic standing positions of the characters OB1 and OB2 of each game machine 10. The selection screen is displayed.

Hereinafter, a case where the player is allowed to select the basic standing position of the character OB1 of one of the game machines 10 will be described as an example.

The player uses the lever 32 to select either "LEFT" or "RIGHT" (step S14).

When "LEFT" in FIG. 9 (A) is selected, the basic standing position of the character OB1 of the game machine 10 is set on the left side of the game screen, and as shown in FIG. 9 (B), "RIGHT" is set. When selected, the basic standing position of the player character OB1 in the game screen is set on the right side of the screen.

Then, the selection instruction data of each player input in this way is written and stored in the selection instruction data storage unit 174 of the own machine as the selection instruction data 174a of the own machine, and is stored in another game machine as an opponent. Is transmitted toward (step S16). At this time, the selection instruction data of the other game machine is also received from the other game machine 10 to be played against, and is written and stored in the selection instruction data storage unit 174 as the selection instruction data 174b of the opponent.

In this way, when the basic standing position of the character OB1 of the own machine is input, the virtual camera control unit 117 of each game machine 10 uses the first and second virtual cameras based on the selection instruction data 174a of the own machine. 300A. It is determined which virtual camera of 300B to use the signal from (step S18).

For example, when the player of the game machine 10 gives a selection instruction so that the basic standing position of the character OB1 of the game machine is on the left side, the image from the first virtual camera 300A is selected as the game image and displayed on the display 20. For example, as shown in FIG. 10A, a game image in which the basic standing position of the character OB1 is on the left side is displayed.

When a selection instruction is given to display the basic standing position of the character OB1 of the game machine 10 on the right side of the screen, the image from the second virtual camera 300B is selected as the game image, and the game machine 10 On the display 20, for example, as shown in FIG. 10B, a game image in which the basic standing position of the character OB1 is on the right side is displayed.

When such a series of processes is completed, a fighting game between the opposing game machines 10 is started (step S20).

On the game machine 10 of each player to play against, the character OB1 of the own machine and the character OB2 of the other machine are displayed facing each other to the left and right, and the player operates the operation unit 30 while looking at this game screen, and the player operates the operation unit 30 of the own machine. You can enjoy the game by operating the characters OB1 or OB2.

At this time, according to the present embodiment, the player of each game machine 10 selects and displays the basic standing position of the character OB of his / her own machine at an arbitrary position on the right side or the left side of the screen according to the player's preference. Therefore, each player can display his / her own character OB1 at the basic standing position that he / she is good at and enjoy the game.

Each game machine 10 transmits and receives operation signals operated by each player via the operation unit 30 as operation code data 176a and 176b at predetermined cycles (for example, 1/60 second). Using these transmitted / received data, each game machine 10 calculates each object space individually and displays this as a game screen. As described above, since the operation code data 176a and 176b may be transmitted and received between the two game machines 10, the amount of data to be transmitted and received is small, and the battle game can be enjoyed in almost real time (steps S30 to 60).

In the present embodiment, when the game is started, the first and second virtual cameras 300A and 300B are switched to either point symmetry control or plane symmetry control according to the progress of the game.

(Point symmetry control)
For example, in the battle defense mode (step S30) in which both players control their own characters OB1 and OB2 using the operation unit 30 and play a game while giving input instructions for attack and defense, the first and the first The second virtual cameras 300A and 300B are controlled so as to be point-symmetrical with respect to the reference point M (step S40).

In such an attack / defense mode, the opposing characters OB1 and OB2 perform attack defense while moving two-dimensionally or three-dimensionally in the object space according to the input of each player.

For example, as shown in FIG. 6, when the first and second characters OB1 and OB2 move to the positions of OB1'and OB2' in the object space, the positions of the reference point and the reference line are also changed accordingly. Move from M, L10 to the position of M', L10'.

With the movement of the first and second characters OB1 and OB2, the first and second virtual cameras 300A and 300B are also controlled to follow the position symmetrically with respect to the new reference point M'. Will be done.

At this time, if the first and second virtual cameras 300A and 300B are controlled to follow the point-symmetrical positions in perfect synchronization with the movement of each character OB1 and OB2, there is a problem that the camera work becomes too fast. appear. Therefore, in the present embodiment, a configuration is adopted in which follow-up control is performed so that the movement and orientation change of the first and second virtual cameras 300A and 300B when the characters OB1 and OB2 move are gentle. For example, by adopting a configuration in which the movement and orientation change of the first and second virtual cameras 300A and 300B are gently controlled by using a virtual damper, it is possible to provide a game image that is easy for each player to see.

As described above, in the attack / defense mode in which each player controls the characters OB1 and OB2 of his / her own machine and inputs the attack / defense, the characters OB1 and OB2 are displayed evenly on the left and right on the game screen. As described above, the first and second virtual cameras 300A and 300B are controlled point-symmetrically with respect to the reference point M. As a result, both characters OB1 and OB2 are displayed on the game machine 10 of each player in an easy-to-see manner, and each player can easily perform an attack / defense operation of his / her own characters OB1 and OB2.

Further, in such an attack defense mode, as described above, the first and second virtual cameras 300A and 300B are basically point-symmetrically controlled at positions orthogonal to the reference line L10. Depending on the situation, for example, as shown in FIG. 8, the first and second virtual cameras 300A. Point symmetry control may be performed at positions 300A'and 300B' that diagonally intersect 300B with respect to the reference line L10.

Thereby, for example, it is possible to display an image in which the character OB of the own machine is projected diagonally from the front over the shoulder of the character OB of the opponent.

(Line symmetry control)
Further, in one example of the present embodiment, when the attack input of one player is successful, the characters OB1 and OB2 in the object space are switched to the attack effect mode that is automatically controlled according to the corresponding attack motion data (step S32). For example, when one player operates the character OB1 of the own machine and succeeds in inputting a continuous attack such as a combo, the character OB1 of the own machine makes a corresponding continuous attack against the character OB2 of the other machine according to a given operation program. Switch to production mode.

In this attack effect mode (step S32), the first and second virtual cameras 300A and 300B are controlled so as to be line-symmetric with respect to the reference line L10.

For example, when one character OB1 switches to an attack effect mode in which a corresponding continuous attack is performed on the other character OB2 according to a given operation program, the first and second virtual cameras 300A and 300B are as shown in FIG. In addition, line symmetry is controlled from the positions indicated by 300A and 300B in the figure to the positions indicated by 300A'and 300B'.

As a result, a series of actions in which one character OB1 makes a corresponding continuous attack on the other character OB2 according to a given action program is displayed as a game image viewed from the diagonal front of one character OB1 and provided. It is possible to enhance the effect of producing an image.

(Camera look control)
Further, when one character OB1 ends a series of continuous attacks on the other character OB2 and one character OB1 wins the other character OB2, the winning character OB1 poses for victory according to given motion data. At the same time, the effect of the camera-looking mode is performed, in which the character looks with the winning camera-looking (step S34). When the effect of the camera line-of-sight mode is started, the camera line-of-sight control for capturing the camera line-of-sight of the winning character OB1 by the third virtual camera (not shown) is performed (step S60).

By performing such a winning effect, it is possible to provide a game image having a higher effect.

In the present embodiment, such a series of processes (steps S30 to 34, S40, S50, S60) is repeated until the game ends (step S36).

By performing a series of controls of the virtual camera as described above, it is possible to provide a game image in which the player can easily operate the character and has a high effect.
