Description

  Some aspects of the present invention relate to a program, an information storage medium, and a game system.

  Conventionally, a game system (image generation system) that generates an image that can be viewed from a virtual camera (a given viewpoint) in an object space that is a virtual three-dimensional space is known, and can experience a so-called virtual reality. As popular.

  For example, there is a game system that performs a process in which a player object attacks an enemy object based on input information of the player (for example, Patent Document 1).

JP-A-8-182860

  However, the conventional game system has a problem that the state after the division when the object is divided due to an impact (for example, an attack) or the like cannot be expressed realistically.

  The present invention has been made in view of the above problems. According to some aspects of the present invention, it is possible to provide a program, an information storage medium, and a game system that can realistically represent the state after the division when the object is divided due to an impact (for example, an attack) or the like.

(1) The present invention
A program for a game device that generates an image in which an object is divided in an object space,
Receiving means for receiving input information;
Representative point position information calculating means for setting a plurality of representative points on the object and calculating position information of the representative points based on the input information;
Determining whether or not the object is divided based on the input information, and when it is determined that there is a division, a division processing unit that performs a division process for dividing the object into a plurality of partial objects;
Based on the position information of the representative point, a divided state determining means for determining a divided state of the object,
The present invention relates to a program for causing a computer to function as processing means for performing at least one of image generation processing or game parameter calculation processing based on the divided state. The present invention also relates to an information storage medium that is a computer-readable information storage medium and stores a program that causes a computer to function as each unit. The present invention also relates to a game system including the above-described units.

  According to the present invention, it is possible to realistically represent a state after division when an object is divided due to an impact (for example, an attack) or the like.

(2) This program, information storage medium, and game system
The representative point is set in association with a part constituting the object,
The split state judging means is
Based on the position information of the representative point associated with the given part and the position information of the representative point associated with the other part, the positional relation between the given part and the other part is obtained. When it is determined that the dividing condition is satisfied, it may be determined that the part including the given part and the part including the other part are in a divided state.

  At least one representative point may be set in association with each part of a plurality of parts constituting the object.

  For example, a positional relationship between a given part and another part before division (for example, a maximum value of a distance that a representative point of a given part and a representative point of another part can take before division) is determined and held. Compare the current positional relationship between the given site and other sites with the location before the division, and based on the comparison result, determine whether the part containing the given site is separated from the part containing the other site. May be.

(3) This program, information storage medium, and game system
The representative point position information calculation means includes:
Position information of the plurality of representative points set in the plurality of partial objects divided after the object division may be calculated.

  By performing computation after separation without computation before separation, the computation load before separation can be reduced. For example, an initial value may be set before separation. If an initial value is set for the representative point, it can be determined that the segment has not been divided.

  When calculating the position information of the representative point after the division, it is preferable to obtain the position information in the same coordinate system. For example, when a given object is divided into a first partial object and a second partial object, the position coordinates of each representative point divided between the first partial object and the second partial object are represented in the world coordinate system. Alternatively, it may be the local coordinate system of the original object before dividing, or the local coordinate system of one of the partial objects after dividing, but it is obtained in the same coordinate system. If it does in this way, the calculation load of the positional relationship of the representative point after division will become light.

  The object data storage unit 179 stores object data. For example, the object data storage unit 179 stores specific points for each part constituting an object (player object, other object) such as a head part, a neck part, and an arm part, and representative points for each object. .

  The information storage medium 180 (computer-readable medium) stores programs, data, and the like, and functions as an optical disk (CD, DVD), magneto-optical disk (MO), magnetic disk, hard disk, and magnetic tape. Alternatively, it can be realized by a memory (ROM), a memory card, or the like.

  The processing unit 100 performs various processes of the present embodiment based on a program (data) input to the information storage medium 180.

  That is, the information storage medium 180 stores a program for causing a computer to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit). The information storage medium 180 may store player personal data, game save data, and the like.

  In the present embodiment, object data may be stored in the information storage medium 180, and the object data stored in the information storage medium 180 may be loaded into the object data storage unit 179 by executing a given program.

  Note that a program (data) for causing a computer to function as each unit of the present embodiment may be downloaded from a server via a network and stored in the storage unit 170 or the information storage medium 180. Such a program stored in the storage unit of the server can also be included in the scope of the present invention.

  The processing unit 100 (processor) performs various processes using the main storage unit 171 in the storage unit 170 as a work area. The functions of the processing unit 100 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs.

  The processing unit 100 includes a representative point position information calculation unit 110, an object space setting unit 111, a movement / motion processing unit 112, a virtual camera control unit 113, a reception unit 114, a division state determination unit 115, a division processing unit 116, and a division line detection. Unit 117, hit effect processing unit 118, game calculation unit 119, drawing unit 120, and sound generation unit 130. Note that some of these may be omitted.

  The object space setting unit 111 includes various objects (polygons, free-form surfaces, or surface objects) representing display objects such as player objects, enemy objects (an example of other objects), buildings, stadiums, cars, trees, pillars, walls, and maps (terrain). The object is arranged and set in the object space. In other words, the position and rotation angle of the object in the world coordinate system (synonymous with direction and direction) are determined, and the rotation angle (rotation angle around the X, Y, and Z axes) is determined at that position (X, Y, Z). Arrange objects.

  The movement / motion processing unit 112 performs a movement / motion calculation (movement / motion simulation) of a player object, an enemy object, a car, an airplane, or the like. That is, based on operation data input by the player through 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). ) Is performed. Specifically, a simulation process for sequentially obtaining object movement information (position, rotation angle, speed, or acceleration) and motion information (position or rotation angle of each part object) every frame (1/60 second). I do. A frame is a unit of time for performing object movement / motion processing (simulation processing) and image generation processing.

  The movement / motion processing unit 112 performs motion processing (motion reproduction, motion generation) for causing the model object (character) to perform motion (animation). This motion processing can be realized by reproducing the motion of the model object based on the motion data stored in the motion data storage unit 172.

  Specifically, the motion data storage unit 172 stores the position or rotation angle of each bone (part object, joint, and motion bone constituting the model object) constituting the skeleton of the model object (3 of the child bone relative to the parent bone). Motion data including the rotation angle around the axis) is stored. The movement / motion processing unit 112 reads the motion data from the motion data storage unit 172, and moves each bone (part object) constituting the skeleton of the model object based on the read motion data (the skeleton shape is changed). Play the model object's motion by transforming it).

  The virtual camera control unit 113 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, a process for controlling the position (X, Y, Z) or the rotation angle (rotation angle about the X, Y, Z axes) of the virtual camera (process for controlling the viewpoint position and the line-of-sight direction) is performed.

  For example, when the player object is photographed from behind by the virtual camera, the position or rotation angle (the direction of the virtual camera) of the virtual camera is controlled so that the virtual camera follows the change in the position or rotation of the player object. In this case, the virtual camera can be controlled based on information such as the position, rotation angle, or speed of the object obtained by the movement / motion processing unit 111. Alternatively, the virtual camera may be controlled to rotate at a predetermined rotation angle or to move along a predetermined movement path. In this case, the virtual camera is controlled based on the virtual camera data for specifying the position (movement path) or rotation angle of the virtual camera. When there are a plurality of virtual cameras (viewpoints), the above control process is performed for each virtual camera.

  The accepting unit 114 accepts player input information. For example, the receiving unit 114 receives player attack input information, player predetermined mode switching input information, direction instruction input information, and the like.

  Based on the position information of the representative point, the divided state determination unit 115 determines the divided state of the object (the presence or absence of the division, the divided part, etc.).

  The division processing unit 116 determines whether or not the object is divided based on the input information. When it is determined that there is a division, the division processing unit 116 performs a division process for dividing the object into a plurality of partial objects. For example, when the player object sets a section of another object based on the attack direction in which the other object attacks, determines whether or not to divide the other object, and when it is determined to divide the other object A process of dividing another object along the dividing line may be performed. Here, the process of dividing the other object along the dividing line is a process of separating the other object into a plurality of objects with the set dividing section as a boundary. When it is determined that another object is to be divided, the division processing unit 116 obtains the vertices of the plurality of objects in real time based on the divided section, and performs processing for generating the plurality of objects.

  The divided line detection unit 117 sets a virtual line connecting the representative points, detects a line divided by the dividing process, and holds divided line information for specifying the divided line.

  The game calculation unit 118 performs game processing based on input data from the input unit 160, a program, and the like. Here, the game calculation includes a process for starting a game when a game start condition is satisfied, a process for advancing the game, a process for placing an object such as a player object, an enemy object or a map, a process for displaying an object, There is a process for calculating a result or a process for ending a game when a game end condition is satisfied.

  In addition, the game calculation unit may perform hit determination. For example, hit determination between a player object and an enemy object (an example of another object) is performed. Here, the player object and the enemy object include weapons (eg, sword, boomerang, ax) possessed by each object. When the process of determining whether or not the player object and the enemy object are hit is performed, the first model object and the second model object are based on the hit area of the player object and the hit area of the enemy object. It may be determined whether or not.

  The game calculation unit 118 calculates game parameters (score, score, physical strength, life, etc.) used for game processing based on the divided state, and performs game calculation based on the game parameters.

  The game calculation unit 118 prepares a plurality of stages, and performs a process of determining whether or not the player object has defeated a predetermined number of enemy objects existing on the stage in each stage. Specifically, based on the hit determination result, a process of changing the physical strength value of the player object (an example of a game parameter) and the physical strength value of an enemy object (an example of a game parameter) is performed. For example, when input information of a player's attack is detected, it is determined that the enemy object has been hit based on the input information of the player's attack by moving and operating the player object (executing the attack motion). Then, a process of subtracting a predetermined value (for example, a damage value corresponding to the attack) from the physical strength value of the enemy object is performed. Then, when the health value of the enemy object becomes zero, it is determined that the enemy object has been defeated. In particular, the game calculation unit 118 according to the present embodiment performs a process of setting the health value of the enemy object to zero when it is determined that the game object has been divided.

  Further, when the player object cannot defend against the attack from the enemy object and receives an attack from the enemy object, a process of subtracting a predetermined value from the physical strength value of the player object is performed. When the player object's physical strength value becomes zero, the game ends.

  The hit effect processing unit 119 performs hit effect processing when it is determined that the player object has hit an enemy object. For example, when it is determined that the enemy object has been divided, the hit effect processing unit 119 performs an image generation process in which liquid is emitted, an image generation process in which light is emitted, and the like from a divided section of the enemy object.

  The effect data storage unit 174 stores effect elements (for example, effect objects and effect textures) having different patterns in association with the divided state. The hit effect processing unit 119 selects a corresponding effect element based on the division state, and performs processing for generating an image using the selected effect element.

  The hit effect processing unit 119 may perform effect processing with different patterns in association with the divided state. For example, the pixel shader may draw the effect emission at the time of cutting with different drawing patterns.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. In the case of generating a so-called three-dimensional game image, first, geometric processing such as coordinate transformation (world coordinate transformation, camera coordinate transformation), clipping processing, or perspective transformation is performed, and drawing data ( Primitive vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) are created. Based on the drawing data (object data), an object (one or a plurality of primitives) after perspective transformation (after geometry processing) is imaged in units of pixels such as an image buffer 173 (frame buffer or intermediate buffer (work buffer)). Draw in a buffer (VRAM) that can store information. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. In addition, when there are a plurality of virtual cameras (viewpoints), the drawing process is performed so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  The drawing unit 120 includes a geometry processing unit 122, a shading processing unit 124, an α blending unit 126, and a hidden surface removal unit 128.

  The geometry processing unit 122 performs geometry processing on the object. Specifically, coordinate processing, clipping processing, perspective conversion, or light source calculation is performed. The object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective transformation) is stored in the object data storage unit 179. The

  The shading processing unit 124 performs a shading process for shading an object. Specifically, the luminance of the drawing pixel of the object is adjusted based on the result of light source calculation (shadow information) performed by the geometry processing unit 122. If necessary, the light source calculation may be performed by the shading processing unit 124 without performing the light source calculation by the geometry processing unit 122. As the shading process, for example, smooth shading such as flat shading, glow shading, and hong shading can be performed on an object.

  The α blending unit 126 performs translucent synthesis processing (normal α blending, addition α blending, subtraction α blending, or the like) based on the α value (A value). For example, in the case of normal α blending, the following processes (1) to (3) are performed.

R _Q = (1−α) × R ₁ + α × R ₂ (1)
G _Q = (1−α) × G ₁ + α × G ₂ (2)
B _Q = (1−α) × B ₁ + α × B ₂ (3)

  In addition, in the case of addition α blending, the following expressions (4) to (6) are performed.

R _Q = R ₁ + α × R ₂ (4)
G _Q = G ₁ + α × G ₂ (5)
B _Q = B ₁ + α × B ₂ (6)

  In the case of subtractive α blending, the processing of the following equations (7) to (9) is performed.

R _Q = R ₁ −α × R ₂ (7)
G _Q = G ₁ −α × G ₂ (8)
B _Q = B ₁ −α × B ₂ (9)

Here, R ₁ , G ₁ , B ₁ are RGB components of an image (original image) already drawn in the image buffer 173, and R ₂ , G ₂ , B ₂ should be drawn in the image buffer 173. This is the RGB component of the image. R _Q , G _Q , and B _Q are RGB components of an image obtained by α blending. 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.

  The hidden surface removal unit 128 performs hidden surface removal processing by the Z buffer method (depth comparison method, Z test) using the Z buffer 175 (depth buffer) in which the Z value (depth information) of the drawing pixel is stored. That is, when the drawing pixel corresponding to the primitive of the object is drawn, the Z value stored in the Z buffer 175 is referred to. Then, the Z value of the referenced Z buffer 175 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 175 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.

  Note that the game system of the present embodiment may be a system dedicated to the single player mode in which only one player can play, or may be a system having a multiplayer mode in which a plurality of players can play.

  Further, when a plurality of players play, game images and game sounds provided to the plurality of players may be generated using one terminal.

  In the game system of the present embodiment, an online game is performed by performing processing of transmitting / receiving data (for example, input information) to / from one or more other game systems connected via a network (transmission line, communication line). You may make it realizable.

2. Outline of the method of the present embodiment 2-1. Game Outline FIG. 2 is a diagram for explaining an outline of the game of the present embodiment.

  The game system of the present embodiment is a game system that generates an image in which an object is divided in an object space. In the present embodiment, the player object PO existing in the object space attacks the enemy object EO (an example of another object). When the game system according to the present embodiment receives attack input information (vertical attack input information and cross attack input information) input from the player, the game system performs an attack motion that cuts the enemy object EO with the sword SD equipped in the player object PO. Process.

  For example, in the present embodiment, when “vertical slashing attack input information” is received, the player object PO is caused to perform a “vertical slashing” attack operation in which the sword SD is swung down from top to bottom. Is received, the player object PO is caused to perform a “horizontal slash” attacking action by swinging the sword SD from right to left or from left to right.

2-2. In this embodiment, when attack input information input from a player is received, a process (an example of a split process) for cutting an enemy object EO that is an attack target is performed.

  For example, in the present embodiment, when “vertical slashing attack input information” is received, as shown in FIG. 3A, a vertical direction (Y-axis direction) that is an attacking direction against the enemy object EO to be attacked. A virtual plane VP parallel to the virtual plane VP is set, and as shown in FIG. 3B, the enemy object EO is separated into a plurality of objects EO1 and EO2 with the virtual plane VP as a boundary.

  When “lateral cut attack input information” is received, as shown in FIG. 4A, the virtual plane VP parallel to the lateral direction (X-axis direction) that is the attack direction with respect to the enemy object EO to be attacked. And the enemy object EO is separated into a plurality of objects EO1 to EO4 with the virtual plane VP as a boundary, as shown in FIG. 4B.

  More specifically, when “vertical slashing attack input information” is received, as shown in FIG. 5A, a line passing through the representative point PP of the player object PO and the representative point EP of the enemy object EO is displayed. A virtual plane VP that is parallel to the vertical direction (Y-axis direction) that is the attack direction is set. Further, as shown in FIG. 5B, a virtual plane VP extending in the direction PV (or moving direction) of the player object PO and parallel to the vertical direction (Y-axis direction) may be set.

  Similarly, when “side-slashing attack input information” is received, as shown in FIG. 6A, the line includes a line passing through the representative point PP of the player object PO and the representative point EP of the enemy object EO, A virtual plane VP parallel to the lateral direction (X-axis direction) that is the attack direction is set. Further, as shown in FIG. 6B, a virtual plane VP extending in the direction PV (or moving direction) of the player object PO and parallel to the horizontal direction (X-axis direction) may be set.

  Thus, the virtual plane VP is set based on the positions of the player object PO and the enemy object EO, the direction of the player object PO, or the attack direction. Further, the virtual plane VP may be moved based on the input information of the direction instruction from the input unit. For example, in the example shown in FIG. 5B, the virtual plane VP may be translated in the horizontal direction (direction perpendicular to the player object direction PV) based on the input information of the direction instruction. In the example shown in B), the virtual plane VP may be translated in the vertical direction (direction perpendicular to the player object direction PV) based on the input information of the direction instruction.

2-3. Configuration of Object to be Splitted A configuration (model information) of an object to be splitted according to the present embodiment will be described.

  As shown in FIG. 7, the model object MOB (character) includes a plurality of part objects (waist 12, chest 14, neck 16, head 18, upper right arm 20, right forearm 22). , Right hand 24, left upper arm 26, left forearm 28, left hand 30, right crotch R32, right shin 34, right foot 36, left crotch 38, left shin 40, and left foot 42). The positions and rotation angles (directions) of these part objects (parts) are the positions of the bones B0 to B19 constituting the skeleton model (positions of the joints J0 to J15) and the rotation angles (the bones of the child relative to the parent bone). Relative rotation angle). Note that these bones and joints are virtual and are not actually displayed objects.

  In the present embodiment, bones (motion bones, joints, part objects) constituting the skeleton of the model object MOB have a parent-child (hierarchical) structure. For example, the parents of the bones B7 and B11 of the hands 24 and 30 are the bones B6 and B10 of the forearms 22 and 28, and the parents of the B6 and B10 are the bones B5 and B9 of the upper arms 20 and 26. The parents of B5 and B9 become the bone B1 of the chest 14, and the parent of B1 becomes the bone B0 of the waist 12. The parents of the bones B15 and B19 of the legs 36 and 42 are the bones B14 and B18 of the shins 34 and 40, the parents of the B14 and B18 are the bones B13 and B17 of the crotch 32 and 38, and the parents of the B13 and B17 are the waist 12 Bones B12 and B16.

  The motion data storage unit 172 stores the positions and rotation angles of these bones (part objects, joints) as motion data. Note that only the rotation angle of the bone may be included in the motion data, and the bone position (joint position) may be included in the model data of the model object.

  For example, it is assumed that the walking motion is composed of reference motions (motions in each frame) M0, M1, M2,. Then, the position or rotation angle of each bone in each of these reference motions M0, M1, M2,... MN is stored in advance as motion data. Then, for example, the position data and the rotation angle of each part object of the reference motion M0 are read out, and then the position and rotation angle of each part object of the reference motion M1 are read out.

In this embodiment, the position information of the representative point of the object is calculated for each frame, and as shown in FIG. 9, the object coordinate OB1 to which the representative point 320 belongs is the position coordinate 330 of the representative point 320 of the object as the object information 310. It is stored in association with.

  The position information 330 of each representative point 320 possessed by the object may be, for example, the position coordinate of each representative point in the world coordinate system or the position coordinate of each object in the local coordinate system. However, when each object has a position coordinate in the local coordinate system, it is preferable to have the position coordinate in the same local coordinate system even when the object is divided into a plurality of partial objects (for example, an object before the division before the division Or the position coordinates in the local coordinate system of one of the partial objects after the division.

  The position information of each representative point that the object has may be held as object information in association with the object. Even after the object is divided into a plurality of partial objects, the position information of each representative point of the object may be managed in association with the object before the division. Further, after the object is divided into a plurality of partial objects, the position information of the representative point after the division may be managed in association with a new divided object to which the representative point belongs, or may be associated with one of the objects. May be managed. For example, management may be performed in association with the main object after division (for example, the main object after division).

  In addition, the position information of each representative point may be stopped for each frame as long as the object exists, regardless of before and after the division of the object, or the plurality of partial objects divided after the division of the object. You may make it calculate the positional information (position coordinates etc.) of the set representative points.

2-5. In the present embodiment, based on the position information of the representative point, the divided state of the object (the presence or absence of division, the divided portion, etc.) is determined.

  FIG. 10 is a diagram for explaining a change in the distance of each representative point when the object OB1 (see FIG. 8) is divided. As shown in the figure, the right part of the head of the object OB1 (see FIG. 8) is divided. In this case, the distance K1 'between the representative point D1' and the representative point D3 'after dividing is the same as the distance K1 between the representative point D1' and the representative point D3 'before dividing. However, the distance L2 between the representative point D1 'and the representative point D2' after the division is longer than the distance K2 between the representative point D1 and the representative point D2 before the division. Since the representative point D1 and the representative point D3 are representative points set in the same part of the same joint, the distance is a constant K1 unless divided. Therefore, when the distance between the representative point D1 and the representative point D3 calculated in a given frame is greater than K1, the part to which the representative point D1 belongs (here B1) and the part to which the representative point D3 belongs (here B3). ) Is divided.

  As shown in the figure, the right foot portion 36 of the object OB1 (see FIG. 8) is divided from the right shin portion 34. In this case, the distance K3 'between the representative point D28' and the representative point D30 'after dividing is longer than the distance K3 between the representative point D28 and the representative point D30 before dividing. Here, the representative point D28 and the representative point D30 are representative points set in different parts of different joints.

  FIG. 11 is a diagram for explaining a change in the positional relationship between the representative point D28 and the representative point D30 before and after the division. Since the right foot portion 36 and the right shin portion 34 are connected by a joint (not shown), the positional relationship between the right foot portion 36 and the right shin portion 34 changes. For example, the right foot portion 36 can take various positional relationships with the right shin portion 34 as shown in 36-1 to 36-3. Therefore, the distance between the representative point D28 and the representative point D30 also changes from K3-1 to K31-3. Therefore, the maximum value K3max of the changeable distance is obtained, and when the distance between the representative point D28 and the representative point D30 is larger than the maximum value K3max of the changeable distance, the part to which the representative point D1 belongs (here, It can be determined that the portion to which the representative point D3 and the representative point D3 belong (here B3) is divided.

2-6. In another aspect of this embodiment, a virtual line connecting representative points is set, and a line divided by the dividing process is detected. The division line information for specifying the divided line is held, and the division state of the object is determined based on the division line information.

  FIG. 13 is a diagram for explaining detection of a virtual line set between representative points and a divided line when the object OB1 (see FIG. 8) is divided. As shown in the figure, when the object OB1 is divided by the first virtual plane 410, a virtual line L1 connecting the representative point D8 and the representative point D10 is divided. As shown in the figure, when the object OB1 is divided by the second virtual plane 420, a virtual line L2 connecting the representative point D1 and the representative point D2, and a virtual line connecting the representative point D3 and the representative point D4. Line L3, a virtual line L4 connecting the representative point D5 and the representative point D6, and a virtual line L5 connecting the representative point D19 and the representative point D20 are divided.

  In the present embodiment, the line divided by the dividing process is detected based on the positional relationship between the position information of each representative point at the time of division and the virtual plane for division set by the input information. And the parting line information for specifying the parted line is hold | maintained. For example, as shown in FIG. 14A, the line ID 452 divided and the representative point information 454 corresponding to the line (representative point ID corresponding to the end point before dividing the line) are used as the divided line information 450, and the divided line belongs. The information may be stored in association with the object OB1.

  In this way, the divided state of the object can be determined at an arbitrary timing after the division by referring to the division line information.

  In addition, considering the joints J1 to J15 in FIG. 7 as representative points and the bones B1 to B19 (the bones correspond to lines connecting the joints) as virtual lines connecting the representative points, the information on the bones to be divided is the division line information. May be stored as

  In this case, as shown in FIG. 14B, a bone ID 462 and a division flag 464 indicating whether or not the bone is divided may be provided as the division line information 460.

2-7. In this embodiment, motion data with different patterns is stored in association with the divided state, the corresponding motion data is selected based on the divided state, and image generation is performed using the selected motion data. I do.

  FIGS. 12A and 12B show different examples of the divided state of the object. FIG. 12A shows a state (first divided state) in which the object OB1 is divided into a first portion 410 including the right crotch 32, right shin 34, and right foot 36 and a second portion 420 other than the first portion 410. Show.

  After the division, the first portion 410 becomes the first partial object, the second portion 420 becomes the second partial object, and both become separate objects that move independently.

  FIG. 12B shows a state in which the object OB1 is divided into a third portion 430 including the lower portion of the left upper arm 26, the left lower arm portion 28, and the left hand portion 30 and a fourth portion 440 other than the third portion 430. Shows a divided state).

  After the division, the third portion 430 becomes a third partial object, and the fourth portion 440 becomes a fourth partial object, and both become separate objects that move independently.

  In such a case, since the divided second portion object and the fourth partial object are different from each other, the motion data to be used is also different.

  In the present embodiment, a plurality of pieces of motion data are prepared in accordance with divided parts for different operations depending on which part of the object is divided.

  For example, when the head is divided (first divided state), the motion data md1 is used to represent the movement of the main body (part other than the head), and the right arm is divided (second divided state). ) Of the main body (part other than the right arm) is used to express the motion of the main body (part other than the left arm) when the left arm is divided (third divided state). In this case, the motion data md3 is used, and the motion data md4 is used to represent the operation of the main body (part other than the right foot) when the right foot is divided (fourth divided state), and the left foot is divided. The motion data md5 is used to represent the operation of the main body (portion other than the left foot) in the case (the fifth divided state).

  In the case of FIG. 12A, since the state is the fourth divided state, the motion data md4 is selected as the motion of the second partial object 420. In the case of FIG. 12B, since the third divided state, the motion data md3 is selected as the motion of the fourth partial object 440.

2-8. Effect Selection According to Divided State In this embodiment, when an enemy object is disconnected due to an attack of a player object, an effect display object indicating damage received by the enemy object EO is drawn in association with the enemy object. In the present embodiment, control is performed so as to display effect display objects with different putters according to the division state of the enemy object.

  FIGS. 15A and 15B are diagrams for explaining the divided state and the effect pattern. FIG. 15A shows a state (first divided state) in which the enemy object EO is divided at the right crotch 32 and an effect display object 450 displayed after the division. FIG. 15B shows a state (second divided state) in which the enemy object EO is divided by the left upper arm 26 and the effect display object 480 displayed after the division at that time.

  Here, as the effect display object, the liquid (oil) released from the enemy object EO (for example, the robot) by the division is shown, but the flame and light emitted from the enemy object EO by the cutting or the parts constituting the robot are shown. Alternatively, it may be displayed as an effect display object.

  In this embodiment, as shown in FIGS. 15A and 15B, effect display objects of different patterns are displayed when the division state of the enemy object EO is different.

  It is also possible to prepare effect objects of different models corresponding to effect display objects of different patterns, select them according to the divided state, and generate an image using the selected effect objects.

  Alternatively, different textures corresponding to effect display objects of different patterns may be prepared, selected according to the division state, and image generation may be performed using the selected texture.

  Also, different shading pattern programs corresponding to effect display objects of different patterns may be prepared, selected according to the division state, and executed by the pixel shader.

2-9. Calculation of Game Parameters In this embodiment, game parameters (scores, physical strength, difficulty level, etc.) may be calculated based on the divided state.

  When the score is calculated based on the divided state, for example, the divided part may be determined based on the divided state of the defeated enemy object, and the score set according to the part may be added. Further, the number of divided parts may be determined based on the divided state, and a score set according to the number of parts may be added.

  In this way, a score corresponding to the damage given to the enemy object EO can be obtained. According to the present embodiment, since the divided state can be determined based on the position information of the representative points and the divided line information, the divided state can be determined at an arbitrary timing during the game. Further, in other modules other than the division processing module, the division state can be determined based on the representative point position information and the division line information.
