Description

  The present invention relates to a game program, and in particular, to a game program that causes a display device to display how a player character moves in a game space.

For example, Patent Document 1 discloses an example of a conventional game device that controls the movement of a player object when approaching a non-player object. In the prior art of Patent Document 1, when a player character approaches a target non-player object, a predetermined action corresponding to the non-player object is executed. For example, when the player approaches the hole, the player character is automatically jumped over the hole without operation by the player. In addition, for example, a game in which a player character is forced to slide when reaching on ice is well known.
JP 2000-153061 A

  In the prior art as described above, a predetermined action (jump, slide, etc.) is performed corresponding to an object (for example, a hole, ice, etc.) expressed so as to be visually recognized on the screen. In other words, the conventional technology merely produces an auxiliary action for the player according to the appearance.

  In addition, since such an auxiliary action is uniformly performed for any player character, for example, even when there are a plurality of types of player characters, all the actions for the target non-player object are the same. End up. However, if there is a large hole in the path, for example, the person will be unable to move due to sluggish legs, or jump over the other side of the road. In the prior art, since different characters or individualities could not be expressed for each character, the game was not interesting.

  Therefore, a main object of the present invention is to provide a game program capable of expressing the inner surface of a player character that is invisible.

  In order to solve the above problems, the present invention employs the following configuration. Note that reference numerals and figure numbers in parentheses indicate correspondence with the best embodiment described later to help understanding of the present invention, and do not limit the scope of the present invention. .

  According to the first aspect of the present invention, there is provided a game device (12) comprising operating means (22, 56) operated by the player, and displaying on the display device (34) how the player character (100) moves in the game space. A game program for controlling the movement of the player character. This game program causes the computer (36) of the game device to function as the following means. The detection means (36, 80, S51, S81) detects movement operation data for instructing movement of the player character output from the operation means. The object generation means (36, 76, S1, S21) generates at least one external force object (102, 108) that affects the movement of the player character in the game space. The correcting means (36, 82, 84, S25-S37, S89-S101) are based on the inner surface information indicating the inner surface of the player character when the position of the player character and the position of the external force object are within a predetermined distance range. Then, movement correction data for moving the player character closer to or away from the external force object is generated. The movement control means (36, 86, 88, S53-S63, S83, S87, S105-S109) controls the movement of the player character based on the movement operation data and the movement correction data.

  According to the first aspect of the present invention, when the player character and the external force object are located within a predetermined distance range in the game space, the player character is brought close to or away from the external force object based on the inner surface of the player character. Movement correction data is generated, and movement of the player character is controlled based on the movement correction data and movement operation data by the player operation. Therefore, the movement is expressed by reflecting the invisible characteristics of the inner surface of the player character in the movement. can do. Specifically, since the operation by the player is less effective, it is possible to know the inner surface of the character sensibly.

  The invention of claim 2 is dependent on claim 1, and the movement correction data includes information on the movement direction. Then, the correction means generates movement correction data for moving the external force object in the direction in which the external force object is located when it is determined that the external force object is a favorite object of the player character based on the inner surface information. When it is determined that the object does not like, the movement correction data for moving the external force object in the radial direction is generated.

  According to the second aspect of the present invention, when the external force object is a favorite object of the player character, correction is made so that the player character approaches the direction in which the external force object is located, while the external force object is an object that the player character dislikes. In some cases, a correction that causes the player character to move away from the external force object in the radial direction occurs, so that the inner surface of the player character can be expressed by a change in the moving direction, and the player's instruction on the moving direction is effective. It becomes difficult to experience the inner surface of the character.

  The invention of claim 3 is dependent on claim 1 or 2, and the movement correction data includes information on the movement amount. And a correction | amendment means changes the movement amount of movement correction data according to the distance of a player character and an external force object.

  According to the invention of claim 3, since the movement amount of the player character changes according to the distance between the player character and the external force object, the inner surface of the player character can be expressed by the change of the movement amount, and the player can You can experience the inside.

  The invention of claim 4 is dependent on any one of claims 1 to 3, and the movement control means calculates the first position coordinates after movement when the player character is moved in the game space based on the movement operation data. First calculating means (S53, S83), second calculating means (S59, S105) for calculating the second position coordinates after movement when the player character is moved in the game space based on the movement correction data, and Third calculation means (S61, S107) for calculating third position coordinates after movement when the player character is actually moved in the game space based on the first position coordinates and the second position coordinates, The player character is moved to the third position coordinate calculated by the means.

  According to the invention of claim 4, since the position of the player character after movement is only calculated by coordinate calculation, movement control can be easily performed.

  A fifth aspect of the invention is dependent on any one of the first to fourth aspects, and the game apparatus further includes an inner surface storage unit that stores inner surface information of a plurality of types of player characters. In this game program, the correction means generates movement correction data based on the inner surface information about the player character that is actually operated.

  According to the invention of claim 5, since the movement correction data is generated based on the inner surface information corresponding to the type of the player character, it is possible to express a different inner surface or individuality for each player character and increase the fun of the game. be able to.

  The invention of claim 6 is dependent on any one of claims 1 to 5, and this game program further causes the computer to function as inner surface setting means for setting inner surface information in accordance with the progress of the game. The correction unit generates movement correction data based on the inner surface information set by the inner surface setting unit.

  According to the sixth aspect of the present invention, the inner surface information is set according to the progress of the game, and the movement correction data is generated based on the inner surface information. Therefore, the change in the inner surface of the player character in accordance with the progress state or state of the game Can be expressed.

  According to the present invention, the movement correction data is generated based on the inner surface of the player character, and the movement is controlled based on the movement correction data as well as the movement operation data by the player. It can be reflected in the operation. That is, the invisible inner surface such as the character and mental state of the player character can be expressed by the action. Specifically, the operation by the player is less effective, and the inner surface of the character can be known through experience.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  Referring to FIG. 1, a video game system 10 to which a game program according to an embodiment of the present invention is applied includes a video game apparatus 12. The video game apparatus 12 is supplied with power, but in the embodiment, this power may be a general AC adapter (not shown). The AC adapter is plugged into a standard household wall socket and converts the household power supply to a low DC voltage suitable for driving the video game device 12. In other embodiments, a battery may be used as the power source.

  The video game apparatus 12 includes a substantially cubic housing 14, and an optical disk drive 16 is provided on the upper end of the housing 14. An optical disk 18, which is an example of an information storage medium storing a game program and data, is mounted on the optical disk drive 16. A plurality of (four in the embodiment) connectors 20 are provided on the front surface of the housing 14. These connectors 20 are for connecting the controller 22 to the video game apparatus 12 by a cable 24. In this embodiment, a maximum of four controllers 22 can be connected to the video game apparatus 12.

  The controller 22 as an operation means operated by the player is provided with an operation unit 26 on the upper surface, the lower surface, or the side surface thereof. The operation unit 26 includes, for example, two analog joysticks (26a, 26b), one cross key (26c), a plurality of button switches (26d, 26e, 26f, 26g, 26h) and the like. One analog joystick is a control stick 26a, and is used, for example, to instruct the movement of a player character (a moving image character that the player can operate with the controller 22). Specifically, the player inputs the moving direction and / or moving speed or moving amount of the player character according to the amount and direction of the inclination of the stick 26a. Another analog joystick is the C stick 26b, which controls, for example, the movement of the virtual camera according to the tilt direction. The cross switch 26c is used to instruct the moving direction of the player character instead of the control stick 26a. The button switches are an A button 26d, a B button 26e, and an X button 26f, which are used, for example, to instruct the player character's movement, and change the viewpoint of the virtual camera of the three-dimensional image and adjust the moving speed of the player character. Used for etc. The button switch is a Y button 26g and controls menu selection, pointer or cursor movement, for example. Further, the button switch is a start / pause button 26h, and is used to start a game or pause the game.

  In this embodiment, the controller 22 is connected to the video game apparatus 12 by a cable 24 provided integrally therewith. However, the controller 22 may be connected to the video game apparatus 12 by other methods, for example, wirelessly via electromagnetic waves (for example, radio waves or infrared rays). The specific configuration of the operation unit 26 of the controller 22 is not limited to the configuration of the embodiment, and can be arbitrarily modified. For example, there may be only one analog joystick (26a, 26b). Further, the cross switch 26c may not be used.

  One or a plurality (two in this embodiment) of memory slots 28 are provided on the front surface of the housing 14 of the video game apparatus 12 and below the connector 20. A memory card 30 is inserted into the memory slot 28. The memory card 30 loads and temporarily stores a game program or the like read from the optical disc 18, or stores game data (for example, game results) of a game played using the game system 10. To be used.

  An AV cable connector (not shown) is provided on the rear surface of the housing 14 of the video game apparatus 12, and the monitor 34 is connected to the video game apparatus 12 through the AV cable 32 using the connector. The monitor 34 is typically a color television receiver, and the AV cable 32 inputs a video signal from the video game apparatus 12 to a video input terminal of the color television and inputs an audio signal to the audio input terminal. Accordingly, for example, a game image of a three-dimensional (3D) video game is displayed on the screen of the monitor 34, and a stereo game sound such as game music or sound effects from the left and right speakers 34a or a surround effect is produced even with two speakers. If possible, game sound including surround sound is output.

  In this game system 10, in order for a user or game player to play a game (or other application), the user first turns on the video game device 12, and then the user wants to play the video game (or other that he / she wants to play). The appropriate optical disk 18 storing the application) is selected, and the optical disk 18 is loaded into the disk drive 16 of the video game apparatus 12. In response, the video game device 12 starts to execute a video game or other application based on the software stored on the optical disc 18. The user operates the controller 22 to provide input to the video game device 12. For example, a game or other application is started by operating one of the operation units 26. By moving other parts of the operation unit 26, the moving image character (player character) is moved in different directions, or the user's viewpoint (camera position) in a three-dimensional virtual game space (hereinafter simply referred to as “game space”). ) Can be changed.

  FIG. 2 is a block diagram showing an electrical configuration of the video game system 10 of FIG. 1 embodiment. The video game apparatus 12 is provided with a central processing unit (hereinafter referred to as “CPU”) 36. The CPU 36 is also called a computer or a processor, and is responsible for overall control of the video game apparatus 12. The CPU or computer 36 functions as a game processor, and a memory controller 38 is coupled to the CPU 36 via a bus. The memory controller 38 mainly controls writing and reading of the main memory 40 coupled via the bus under the control of the CPU 36. A GPU (Graphics Processing Unit) 42 is coupled to the memory controller 38.

  The GPU 42 forms a part of the drawing means, and is composed of, for example, a single chip ASIC. The GPU 42 receives a graphics command (graphics command) from the CPU 36 via the memory controller 38, and the geometry unit 44 and the rendering according to the command. A unit 46 generates a 3D game image. That is, the geometry unit 44 rotates various characters and objects (consisting of a plurality of polygons. The polygon is a polygonal plane defined by at least three vertex coordinates), Coordinate calculation processing such as movement and deformation is performed. The rendering unit 46 performs image generation processing such as pasting a texture (Texture: pattern image) on each polygon of various objects. Therefore, 3D image data to be displayed on the game screen is created by the GPU 42, and the image data is stored in the frame buffer 48.

  Note that data (primitives, polygons, textures, etc.) necessary for the GPU 42 to execute the drawing command is acquired from the main memory 40 by the GPU 42 via the memory controller 38.

  The frame buffer 48 is a memory for drawing (accumulating) image data for one frame of the raster scan monitor 34, for example, and is rewritten frame by frame by the GPU. Specifically, the frame buffer 48 stores image color information in order for each pixel (pixel). Here, the color information is data about R, G, B, and A. For example, 8-bit R (red) data, 8-bit G (green) data, 8-bit B (blue) data, and 8 Bit A (alpha) data. The A data is data about the mask (mat image). A video I / F 58 described later reads data from the frame buffer 48 via the memory controller 38, whereby a 3D game image is displayed on the screen of the monitor 34.

  The Z buffer 50 has a storage capacity corresponding to the number of pixels corresponding to the frame buffer 48 × the number of bits of depth data per pixel, and the depth information or depth of the dots corresponding to each storage position of the frame buffer 48. Data (Z value) is stored.

  Note that both the frame buffer 48 and the Z buffer 50 may be configured using part of the main memory 40.

  The memory controller 38 is also coupled to the ARAM 54 via a DSP (Digital Signal Processor) 52. Therefore, the memory controller 38 controls writing and / or reading of not only the main memory 40 but also the ARAM 54 as a sub memory.

  The DSP 52 functions as a sound processor and uses sound data stored in the main memory 40 or uses sound waveform data written in the ARAM 54, and thereby audio data corresponding to sound, voice or music necessary for the game. Is generated.

  Memory controller 38 is further coupled to each interface (I / F) 56, 58, 60, 62 and 64 by a bus. The controller I / F 56 is an interface for the controller 22 and supplies an operation signal or data of the operation unit 26 of the controller 22 to the CPU 36 through the memory controller 38.

  The video I / F 58 accesses the frame buffer 48, reads the image data created by the GPU 42, and supplies the image signal or image data (digital RGBA pixel value) to the monitor 34 via the AV cable 32 (FIG. 1).

  The external memory I / F 60 links the memory card 30 (FIG. 1) inserted in the front surface of the video game apparatus 12 to the memory controller 38. Thereby, the CPU 36 can write data to the memory card 30 or read data from the memory card 30 via the memory controller 38.

  The audio I / F 62 receives the audio data supplied from the DSP 52 or the audio stream read from the optical disc 18 through the memory controller 38 and supplies an audio signal (audio signal) corresponding to the audio data to the speaker 34 a of the monitor 34.

  The disk I / F 64 couples the disk drive 16 to the memory controller 38, and thus the CPU 36 controls the disk drive 16. Program data, texture data, and the like read from the optical disk 18 by the disk drive 16 are written into the main memory 40 under the control of the CPU 36.

  FIG. 3 shows a memory map of the main memory 40. The main memory 40 includes a game program storage area 70 and a data storage area 72. The game program storage area 70 includes a game main processing program 74, an image generation program 76, an image display program 78, an operation signal detection program 80, a distance calculation program 82, a correction program 84 using an external force, a movement position calculation program 86, and a movement control program. A program such as 88 is stored.

  The game main processing program 74 is a program for processing a main routine for a game executed by the video game apparatus 12. The image generation program 76 is a program that generates a 3D game image. The 3D game image includes a moving image character such as a player character that appears in the game and whose operation is controlled by the player (may be controlled by the computer (CPU 36)). Further, the non-player objects that are not operated by the player include items used by the player character, background objects of the game (such as terrain objects, wall objects, building objects, and floor (ground) objects). Furthermore, in this embodiment, the non-player object includes an external force object that exerts an influence on the movement by applying a repulsive force or an attractive force corresponding to the inner surface of the player character. At least one external force object is generated in the game space. The external force objects include, for example, objects such as confectionery and vegetables that are fixedly arranged at predetermined positions in the game space, and objects such as dogs and cats that can move in the game space. The image display program 78 is a program for displaying the 3D game image generated by the image generation program 76 on the monitor 34 as a two-dimensional game screen.

  The operation signal detection program 80 is a program for detecting an operation input signal output from the controller 22, and an arbitrary action such as movement, jump, attack (shoot, hit, throw, apply magic, change) of the player character. An operation signal or operation data (including movement operation data for instructing movement) is detected.

  The distance calculation program 82 is a program for calculating the distance between the player character and the external force object based on the position of the player character and the position of the external force object.

  The external force correction program 84 is a part of correction means. When the position of the player object and the position of the external force object are within a predetermined distance range, the external force (ie, repulsive force or attractive force) is based on the inner surface of the player character. ) To correct the position of the player character. That is, movement correction data for correcting movement so as to bring the player character closer to the external force object by attractive force is generated, or movement correction data for correcting movement so as to move the player character away from the external force object by repulsive force. The inner surface of the player character includes, for example, personality, mental state, and the like, but is collectively shown in the likes and dislikes relationship between the player character and the external force object as will be described later. The attractive force works when the external force object is a favorite object of the player character, and the repulsive force works when the external force object is an object disliked by the player character. The generated movement correction data includes information about the moving direction. As will be described later, correction data for moving in the direction in which the external force object is positioned is generated when an attractive force is applied, and an external force is applied when a repulsive force is applied. Correction data for moving the object in the radial direction is generated. Further, the movement correction data includes information on the movement amount or movement speed, and as will be described later, the magnitude of the repulsive force or attractive force to be applied, that is, the degree of correction, is determined according to the distance between the player character and the external force object, for example. Is done. In this embodiment, the closer to the external force object, the larger the external force, that is, the larger the correction value. The correction value based on repulsive force or attractive force may be set to be the same within a predetermined range, for example.

  The movement position calculation program 86 is a program for calculating the position coordinates of the player character after moving in the game space based on the player's operation (movement operation data) and correction by external force (movement correction data). The movement control program 88 is a program for moving the player character based on the position coordinates after movement calculated by the movement position calculation program 86.

  The data storage area 72 includes an image data area 90, a map data area 92, an inner parameter area 94, a player character position data area 96, an external force object position data area 98, and the like.

  The image data area 90 stores data such as polygon data and texture data for generating a 3D game image as described above. Specifically, the image data is about the above-described player character, item, background object, external force object, and the like. The map data area 92 stores data related to the map of the game space.

  The inner surface parameter data area 94 stores inner surface information indicating the inner surface (inner surface characteristics) of the player character. The inner surface of the player character is aggregated into elements of likes or dislikes, and is indicated by a like / dislike relationship between the player character and the external force object. As shown in FIG. 4, the inner surface parameter data includes inner surface information for each type of player character in the case of a game in which a plurality of types of player characters are prepared. That is, in the inner surface parameter data, for example, what is a favorite object and what is a dislike object is registered in advance for each type of player character. Based on the inner surface parameter, in the above-described correction program using an external force, it is determined whether the external force applied between the player character and the external force object is a repulsive force or an attractive force. In the example of FIG. 4, in the case of the player character A, dogs, confectionery,... Are set as favorite objects, and cats, vegetables,. Therefore, when playing the game with the player character A, if the distance from the dog or confectionery is within the predetermined distance range, the attractive force is activated, and the distance from the cat or vegetable is within the predetermined distance range. When you do, repulsion works.

  The inside is concentrated on likes or dislikes, but it is not limited to emotional likes and dislikes. For example, what a player character needs or wants may be set as a favorite object, and what a player character does not need may be set as a dislike object.

  Further, the inner surface parameter data may be set for a favorite player character and a disliked player character for each type of external force object.

  The player character position data area 96 stores position coordinates of the player character in the game space. The external force object position data area 98 stores the position coordinates of each external force object in the game space.

  In the main memory 40, although not shown, sound data about music (BGM) played during the game and sound effects, game data and flag data generated as the game progresses, etc. Is also remembered.

  In the game system 10, for example, an action game in which a player character moves in a game space is performed. The player operates the controller 22 to control any action such as movement of the player character. An operation command or an operation signal output from the controller 22 is given to the controller I / F 56. The CPU 36 obtains an operation signal temporarily stored in a controller buffer (not shown) provided in the controller I / F 56 every predetermined cycle (for example, one frame), for example, at the timing of V retrace. Note that the timing of the V retrace is generated by the GPU 42 that generates the 3D game image, and the CPU 36 acquires it.

  Here, the format of the operation signal output from the controller 22 to the video game apparatus 12 will be described with reference to FIG. However, the operation signal has a format corresponding to a standard controller (controller 22 in FIG. 1) of the video game apparatus 12 (in this embodiment, “GAME CUBE (product name)” manufactured and sold by the applicant of the present application).

  Although not shown in FIG. 1, an R trigger button, an L trigger button, and a Z trigger button as button switches are further provided on the side of the controller 22 where the cable 24 is provided.

  As can be seen from FIG. 5, the operation signal is composed of 8 bytes, and in the first byte (1st byte), from bit 7 (b7) to bit 0 (b0) in order, “0”, “0”, “ Data on ORG_CH "," START "," Y "," X "," B ", and" A "is written. Bits 7 and 6 have a fixed value “0”, and bit 5 is written with data indicating ON / OFF of the setting mode “ORG_CH”. In this embodiment, “1” is written when the setting mode “ORG_CH” is on, and “0” is written when the setting mode “ORG_CH” is off. Here, “ORG_CH” is a variable for a mode (setting mode) for setting whether or not to reset the reference position (the origin (neutral position) of the joystick (26a, 26b)). Bits 4 to 0 are written with data indicating ON / OFF of the start / pause button 26h, Y button 26g, X button 26f, B button 26e and A button 26d. In this embodiment, “1” is written to the corresponding bit when the button switch is on, and “0” is written to the corresponding bit when the button switch is off.

  In the second byte (2nd byte), from bit 7 to bit 0 in order, “FIN”, “L”, “R”, “Z”, “UP”, “DOWN”, “RIGHT” and “LEFT” Data is written. Bit 7 is written with data indicating ON or OFF of the mode “FIN” for identifying the controller. In this embodiment, “1” which is ON is written in the case of the standard controller, and OFF in the case of an operating device different from the standard controller (an operating device imitating a handgun or an operating device imitating a musical instrument). A certain “0” is written. Bit 6 to bit 0 indicate ON / OFF of each of the L trigger button, R trigger button, Z button, UP (up) button, DOWN (down) button, RIGHT (right) button, and LEFT (left) button. Data is written. The data value written in each bit is the same as the button switch such as the start / pause button 26h described above.

  The UP (up) button, DOWN (down) button, RIGHT (right) button, and LEFT (left) button are buttons of the cross switch 26c.

In the third byte, data indicating the tilt amount of the control stick 26a in the X direction is written as binary data using all 8 bits. Therefore, the inclination in the X direction is expressed by “00000000” (decimal number “0”) to “11111111” (“255”). For example, when the control stick 26a is tilted to the left, it approaches “0”, and when it is tilted to the right, it approaches “255”.

  In the default setting, since the neutral position is “128 (01000000)”, it can be seen that if it is smaller than this, the control stick 26a is tilted to the left, and if it is larger, it is tilted to the right. I understand that. Further, the amount of inclination can be detected by the difference between the acquired data value and the data value of the neutral position.

In the fourth byte (4th byte), data indicating the tilt amount of the control stick 26a in the Y direction is written as binary data using all 8 bits. Therefore, the inclination in the Y direction is also expressed by “00000000” (decimal number “0”) to “11111111” (“255”), as in the X direction. For example, when the control stick 26a is tilted downward, it approaches “0”, and when it is tilted upward, it approaches “255”.

  In the default setting, since the neutral position is “128 (01000000)”, it can be seen that if it is smaller than this, the control stick 26a is tilted downward, and if it is larger, it is tilted upward. I understand that. Further, the amount of inclination can be detected by the difference between the acquired data value and the data value of the neutral position.

  When the control stick 26a is tilted in the oblique direction, both the third byte data and the fourth byte data are data values other than the neutral position data value “01000000”.

In the fifth byte (5th byte), data indicating the tilt amount in the X direction of the C stick 26b is written as binary data using all 8 bits. In the 6th byte, data indicating the tilt amount in the Y direction of the C stick 26b is written as binary data using all 8 bits. These data values are determined in the same manner as in the case of the control stick 26a described above.

In the seventh byte (7th byte), data indicating the amount of pressing of the L trigger button is written as binary data using all 8 bits. The data value when the L trigger button is not pressed is “00000000”, the data value is increased according to the amount of pressing, and the data value when pressed to the maximum is “11111111”.

In the 8th byte, data indicating the push amount of the R trigger button is written in a binary number using all 8 bits. The method for determining the data value is the same as that for the L trigger button.

  Such an operation signal is output from the controller 22 (22a, 22b), and the CPU 36 acquires it, and controls an arbitrary action such as movement of the player character as described above. As an example, the movement of the player character is controlled by the tilt direction and tilt amount of the control stick 26a. Specifically, when the CPU 36 obtains an operation signal from the controller 22, the CPU 36 calculates the position (position coordinates) of the player character after movement according to the tilt direction and the tilt amount of the control stick 26a included in the operation signal. For example, the moving amount or moving speed when the control stick 26a is tilted 100% in the up, down, left, right, or diagonal directions (tilted) is determined in advance. Variable. In addition, the three-dimensional position (position coordinates of the current position) of the player character in the game space is monitored by the CPU 36 and stored in the player character position data area 96. Therefore, when the movement direction and the movement amount are detected from the operation signal, the position coordinates after movement when moving the player character in the game space based on the operation signals (hereinafter referred to as “first position coordinates”) are calculated. be able to.

  In the game space of this embodiment, at least one external force object is arranged or moved at a predetermined position. When the player character operated by the player enters a predetermined distance range from the external force object, that is, when the position of the player character and the position of the external force object are within the predetermined distance range, the external force acts on the player character. As described above, the player character is provided with the inner surface parameter, and the type of external force is determined based on the inner surface parameter. That is, when the external force object is an object that the player character dislikes, a repulsive force acts on the player character so as to move away from the external force object. On the other hand, if the external force object is a favorite object of the player character, an attractive force acts on the player character so as to approach the external force object. Therefore, the movement of the player character is not determined only by the operation input signal by the player within the predetermined distance range, but is corrected by the influence of the external force based on the inner surface parameter. Similarly to the operation input data, the correction data based on the external force includes information on the movement direction and the movement amount, and thereby the movement direction and the movement amount of the operation input data are corrected. Therefore, the inner surface of the player character can be expressed by a change in the moving direction and moving amount of the player character. Specifically, since the operation by the player is difficult to work, the player can know the inner surface of the character sensiblely.

  FIG. 6 shows an example of a movement vector due to an operation input and repulsion when the player character 100 falls within a predetermined distance range from the object 102 that the player character 100 dislikes. The external force object 102 that the player character 100 dislikes is set with a predetermined area where repulsive force acts when the player character 100 enters. The predetermined region in the example of FIG. 6 is a range surrounded by the outer periphery D1 having the first distance from the external force object 102, and the outer periphery D1 and the inner periphery D2 having the second distance smaller than the first distance. The first region 104 therebetween and the second region 106 surrounded by the inner periphery D2 are included. In FIG. 6, the outer periphery D1 and the inner periphery D2 are clearly indicated by broken lines for convenience.

  In the first area 104 and the second area 106, a repulsive force in the radial direction acts on the player character 100 from the external force object 102, and the movement of the player character 100 is corrected by the influence of the repulsive force. In this embodiment, the magnitude of the correction value due to repulsion changes according to the distance between the player character 100 and the external force object 102, for example. The second region 106 is set to a constant value (100% or the like), for example. That is, since the movement amount of the player character is changed according to the distance between the player character 100 and the external force object 102, the inner surface of the player character can be expressed more prominently as it approaches the external force object. Note that the magnitude of the correction value by the external force corresponds to the amount of inclination of the control stick 26a.

  Therefore, when the player enters the first region 104 in the outer periphery D1, the player feels that the pressure to be pushed back outwards becomes more and more intense. When the magnitude of the correction value due to the repulsive force of the second area 106 is set to 100%, the player cannot approach the center further from the inner circumference D2. If the correction value due to repulsive force in the second area 106 is set to be smaller than 100%, the player can reach the second area 106 and cross it. In addition, when the player enters the outer periphery D1 and releases his hand from the control stick 26a, for example, the player character 100 is pushed back. If the control stick 26a is left in the neutral position as it is, the player character 100 is finally pushed back to the end of the outer periphery D1. The speed at which the player character 100 is pushed back decreases as the player character 100 moves away from the inner circumference D2.

  The size of the predetermined area, that is, the distance from the center (the position of the external force object 102) to the outer periphery D1 and the inner periphery D2, may be set in common to all types of external force objects 102, but the external force object 102 It may be set differently depending on the type (dog, cat, etc.). In this case, the degree of likes and dislikes for each external force object of the player character can be expressed by the influence of the external force and the starting distance. Further, the distance defining the predetermined area may be set to be different depending on the type of the player character 100 even for the same type of external force object 102. In this case, the degree of likes and dislikes for each player character can be expressed, and different internal characteristics can be produced for each player character, so that the fun of the game can be increased.

  Similarly, the magnitude of the correction value due to repulsive force or attractive force within the predetermined area and the manner of change according to the distance of the correction value may be set in common to all external force objects 102. It may be set differently depending on the type of 102. In this case, the degree to which the player character likes and dislikes the external force object can be expressed by the magnitude of the external force. Further, the magnitude of the correction value, the manner in which the correction value is changed, and the like may be set to be different depending on the type of the player character 100 for the same type of external force object 102. In this case, a difference in the degree of likes and dislikes for each player character can be expressed to produce a difference in the inner surface characteristics of each player character.

  The position coordinates after movement of the player character 100 within the predetermined distance range are determined based on the movement operation data and movement correction data by repulsion. In FIG. 6, in order to show the current position of the player character 100 and the position after the movement in an easy-to-understand manner, the movement direction and the movement amount (movement speed) by the operation input and the repulsive force are expressed as vectors (hereinafter referred to as “movement vectors”). expressing. The player character 100 is moved according to a combined vector (solid line) of a movement vector (long broken line) by an operation input and a movement vector (dotted line) by repulsion. Specifically, the position coordinates after movement of the player character 100 are calculated by coordinate calculation, and therefore movement control can be easily performed. That is, the first position coordinates after movement when moving based on the operation input are calculated, and the position coordinates after movement when moving the player character in the game space based on the correction value by repulsion (hereinafter, “ 2nd position coordinate ") is calculated. Based on the calculated first position coordinates and second position coordinates, position coordinates after movement when the player character 100 is actually moved in the game space (hereinafter referred to as “third position coordinates”) are calculated. To do. The state in which the player character 100 moves to the third position coordinate in the game space is displayed on the monitor 34.

  The operation input from the controller 22 is given in the local coordinate system of the player character 100. In the local coordinate system, the advancing direction of the player character 100 is the Y axis and the lateral direction is the X axis. On the other hand, since the repulsive force or attractive force is given in the world coordinate system, the correction value by the external force is converted into the local coordinate system and then added to the data of the operation input X axis and Y axis.

  A specific example of the movement control of the player character 100 within a predetermined distance range of the external force object to which the repulsive force is applied will be described with reference to FIG. FIG. 7 shows a movement vector due to an operation input, a movement vector due to repulsive force, and their combined vectors in several situations.

  In FIG. 7A, the player performs an operation input of 100% leftward movement toward the object 102 that he dislikes. On the other hand, 50% rightward repulsive force acts on the player character 100 from the object 102 that he dislikes. The movement vector by the operation input and the movement vector by the repulsive force are combined, and the player character 100 is moved according to the combined vector. In this case, the player character 100 moves 50% to the left. Therefore, the player feels that it is difficult to approach the external force object 102 by the force that is pushed back.

  In FIG. 7B, the player performs a 70% rightward operation input away from the object 102 that he dislikes. The player character 100 receives a repulsive force 50% to the right from the object 102 that he dislikes. In this case, the player character 100 is moved 100% to the right. The movement of the player character does not exceed 100% at the maximum. Since the movement amount is larger than the actual operation input, the player feels that the external force object 102 is being pushed back.

  In FIG. 7C, the player does not perform the operation input, and the player character 100 is subjected to a repulsive force 50% to the right from the object 102 that he dislikes. In this case, the player character 100 moves 50% to the right. If no operation is performed, the player character 100 is moved away from the external force object 102 and pushed out of the predetermined area.

  In FIG. 7D, the player performs a 100% leftward operation input toward the object 102 that he dislikes. On the other hand, the player character 100 receives 100% rightward repulsion from the object 102 that he dislikes. In this case, the player character 100 does not move and cannot approach the object 102 that he dislikes. The situation in FIG. 7D corresponds to an example when the correction value due to repulsion in the second region 106 in FIG. 6 is set to 100%, for example.

  In this way, when the player character 100 approaches the dislike object 102, repulsive force that moves away from the dislike object 102 acts on the player character 100, and specifically, movement correction data that moves away from the dislike object 102. Is generated and its movement is affected. FIG. 8 shows an example of a trajectory of movement when the player character 100 approaches the external force object 102 that the player character 100 dislikes. FIG. 8 shows a situation in which an operation input to move upward in FIG. 8 is given by the player and the side of the disliked external force object 102 is attempted to pass. When the player character 100 enters the outer periphery D1, radial repulsive force from the external force object 102 acts. Due to this repulsive force, the player character 100 moves upward while being kept away from the external force object 102. Further, since the player character 100 enters a predetermined region from the diagonally lower left direction of the external force object 102, the moving speed is repulsive for a while until it enters the outer periphery D1 and reaches the side of the external force object 102. Since the component in the direction opposite to the traveling direction works, the speed becomes slower, and thereafter the speed becomes faster. The player understands that the external force object 102 has an influence on the inner surface of the player character by observing the movement of the player character 100 different from his own operation. In this case, he dislikes the external force object 102. I understand that.

  On the other hand, FIG. 9 shows an example of a movement vector based on an operation input and an attractive force when the player character 100 enters a predetermined distance range from the favorite object 108. A predetermined area where an attractive force acts when the player character 100 enters is set in the external force object 108 that the player character 100 likes. 9 also includes the first region 104 between the outer periphery D1 and the inner periphery D2, and the second region 106 surrounded by the inner periphery D2, similarly to the example of FIG. 6 described above. .

  In the first area 104 and the second area 106, the player character 100 is attracted in the direction in which the external force object 108 is located, and the movement of the player character 100 is corrected by the influence of the attractive force. In this embodiment, the magnitude of the correction value due to the attractive force also changes according to the distance between the player character 100 and the external force object 108, for example, and the player character 100 approaches the inner circumference D2 or the external force object 108 in the first region 104. The second region 106 is set to a constant value (100%, etc.), for example.

  Therefore, when the player enters the first area 104 in the outer periphery D1, the player feels that the pressure pulled toward the external force object 108 becomes stronger. When the player enters the outer periphery D1 and releases his / her hand from the control stick 26a, for example, the player character 100 is attracted toward the external force object. If the control stick 26a is left in the neutral position as it is, the player character 100 is drawn to the inner circumference D2. The drawing speed increases as the player character 100 approaches the inner circumference D2. When the magnitude of the correction value due to the attractive force of the second area 106 is set to 100%, the player can no longer leave the second area 106 when reaching the inner circumference D2, and the center (external force) Will be drawn to the object 108). In addition, when the correction value by the attractive force of the second area 106 is made smaller than 100%, the player can escape from the second area 106 even if the player reaches the second area 106.

  Position coordinates after movement of the player character 100 within the predetermined distance range are determined based on movement operation data and movement correction data based on attractive force. The player character 100 is moved according to a combined vector (solid line) of a movement vector (long broken line) by an operation input and a movement vector (dotted line) by attractive force. Specifically, the position coordinates after movement of the player character 100 are calculated by coordinate calculation, as in the case of the repulsive force described above. That is, the first position coordinates after movement when moving based on the operation input are calculated, and the second position coordinates after movement when moving based on the correction value by the attractive force are calculated. Then, based on the calculated first position coordinates and second position coordinates, the third position coordinates after movement when the player character 100 is actually moved are calculated.

  A specific example of the movement control of the player character 100 within a predetermined distance range of the external force object 108 on which the attractive force is applied will be described with reference to FIG. FIG. 10 shows a movement vector by an operation input, a movement vector by an attractive force, and a combined vector thereof in some situations.

  In FIG. 10A, the player performs an operation input of 100% rightward movement away from the favorite object 108. On the other hand, the player character 100 receives an attractive force 50% leftward from the favorite object 108. The movement vector by the operation input and the movement vector by the attractive force are combined, and the player character 100 is moved according to the combined vector. In this case, the player character 100 moves 50% to the right. Therefore, the player feels that it is difficult to leave by the force attracted to the external force object 108.

  In FIG. 10B, the player performs a 70% leftward operation input toward the favorite object 108. The player character 100 is attracted 50% from the favorite object 108 in the left direction. In this case, the player character 100 is moved 100% leftward. The movement of the player character does not exceed 100% at the maximum. Since the movement amount is larger than the actual operation input, the player feels that the player is pulled by the external force object 108.

  In FIG. 10C, the player has not performed an operation input, and the player character 100 is subjected to an attractive force of 50% leftward from the favorite object 108. In this case, the player character 100 moves 50% to the left. If nothing is operated, the player character 100 is finally drawn to the external force object 108.

  In FIG. 10D, the player performs 100% rightward operation input away from the favorite object 108. On the other hand, the player character 100 is attracted 100% from the favorite object 108 in the left direction. In this case, the player character 100 does not move and cannot leave the favorite object 108. The state of FIG. 10D corresponds to an example when the correction value by attractive force is set to 100% in the second region 106 of FIG.

  In this way, when the player character 100 approaches the favorite object 108, the attractive force attracted to the favorite object 108 acts on the player character 100, and specifically, movement correction data that approaches the favorite object 102. Is generated and its movement is affected. FIG. 11 shows an example of a trajectory of movement when the player character 100 approaches the favorite external force object 108. FIG. 11 shows a situation in which an operation input to move upward in FIG. 11 is given by the player, and the player wants to pass the side of the favorite external force object 108. When the player character 100 enters the outer periphery D1, an attractive force that tries to attract the external force object 108 acts. Due to this attractive force, the player character 100 moves upward while approaching the external force object 108. In addition, since the player character 100 enters a predetermined region from the diagonally lower left direction of the external force object 108, the moving speed advances by attraction until it enters the outer periphery D1 and reaches the side of the external force object 108. The direction component works faster, and then slows down. The player feels the difficulty of his / her own controller operation and sees the movement of the player character 100 different from his / her instruction, so that the external force object 108 affects the inner surface of the player character 100. It is understood that the player character 100 likes the external force object 108 in this case.

  FIG. 12 shows an example of the game operation in the game system 10. When the game is started, as shown in FIG. 12, the CPU 36 sets and updates the game space in step S1. By this processing, the terrain, player character, and other objects are arranged in the game space at the start of the game or when the scene is switched, and thereafter, the respective positions and movements are updated. Next, the CPU 36 executes a non-player object control process in step S3. Details of the control processing of the non-player object are shown in FIG. 13, and correction by an external force object is processed as will be described later. Subsequently, in step S5, the CPU 36 executes a player character control process. The details of the player character control process are shown in FIG. 14, and the movement of the player character is controlled as will be described later. In step S <b> 7, the CPU 36 generates a game image using the GPU 42 and displays it on the monitor 34. Then, the CPU 36 repeats the processing from step S1 until the game is finished in step S9, advances the game, and displays a game image. The processing from step S1 to step S9 is executed at a predetermined cycle, for example, every frame.

  FIG. 13 shows an example of the operation of the non-player object control process in step S3 (FIG. 12). In the first step S21 of FIG. 13, the CPU 36 controls each action of the non-player object existing in the game space set or updated in step S1 (FIG. 12). For example, for a non-player object that moves, the position after the movement is calculated.

  Next, in step S23, it is determined whether or not an external force object exists in the game space. The presence / absence of the external force object may be searched in another predetermined range such as a range displayed as a game image or a range that can be seen by the player character. If “NO” in the step S23, it is not necessary to perform the correction of the operation input by the external force object, so the control process of the non-player object is ended and the process returns to the step S5 in FIG.

  On the other hand, if “YES” in the step S23, that is, if the external force object exists in a predetermined range such as in the game space, the CPU 36 refers to the inner surface parameter data (FIG. 4) in a step S25. Then, a player character that is a target to which an external force is applied by the external force object is searched. That is, one external force object is selected from the external force objects determined to be present in the game space or the like in step S23, and the external force object is registered as a favorite or disliked object of the player character in the inner surface parameter data. Is searched. The favorite parameter and the dislike object are registered for each of the plurality of player characters in the inner parameter, but when only one type of player character appears in the game space as in this embodiment, the game starts. For example, only the data related to the player character that is selected and actually operated by the player may be referred to.

  In step S27, the CPU 36 determines whether or not the player character is a target to which an external force is applied by the external force object. If “NO” in the step S27, that is, if the external force object is neither a favorite object or a dislike object of the player character, the process proceeds to a step S39.

  On the other hand, if “YES” in the step S27, that is, if the external force object is an object that the player character likes or dislikes, in a succeeding step S29, the CPU 36 determines the current position data of the player character. And the distance between the player character and the external force object are calculated based on the position data of the external force object.

  In step S31, the CPU 36 determines whether or not the player character is within a predetermined distance range of the external force object based on the calculated distance. That is, for example, it is determined whether or not the calculated distance between the player character and the external force object is smaller than the distance from the external force object to the outer periphery D1 (FIGS. 6 and 9). If “NO” in the step S31, that is, if the player character exists outside the predetermined distance range of the external force object, the process proceeds to a step S39.

  On the other hand, if “YES” in the step S31, that is, if the player character exists within a predetermined distance range from the external force object, in a subsequent step S33, the CPU 36 determines whether the external force object is an object that the player character dislikes or Judge whether it is a favorite object.

  If “YES” in this step S33, that is, if the external force object is an object which is disliked, in a subsequent step S35, the CPU 36 determines a correction value by repulsive force according to the distance between the player character and the external force object. The operation correction data is output to a predetermined area of the data storage area 72. When step S35 ends, the process proceeds to step S39. The correction value based on the external force may be calculated based on the distance between the external force object and the player character. For example, a correction value data table in which correction values associated with each predetermined distance are registered is stored in advance. In this case, the decision may be made with reference to the data.

  On the other hand, if “NO” in the step S33, that is, if the external force object is a favorite object, in a succeeding step S37, the CPU 36 calculates a correction value based on the attractive force according to the distance between the player character and the external force object. Then, the operation correction data is output to a predetermined area of the data storage area 72. When step S37 ends, the process proceeds to step S39.

  In step S39, the CPU 36 determines whether or not the processing has been completed for all the external force objects detected in step S23. If “NO” in this step S39, the process returns to the step S25 to select one from the remaining external force objects, and the processing after the step S25 is executed for the external force object in the same manner as described above. In this manner, the process is repeated until “YES” is determined in the step S39, and determination of necessity of correction, determination of a correction value, and the like are performed for all external force objects existing in the game space or the like. On the other hand, if “YES” in the step S39, the control process of the non-player object is ended, and the process returns to the step S5 in FIG.

  FIG. 14 shows an example of the operation of the player character control process in step S5 (FIG. 12). In the first step S51 of FIG. 14, the CPU 36 detects an operation input. That is, the operation signal temporarily stored in the control buffer of the controller I / F 56 is acquired, for example, at the timing of V retrace. As a result, movement operation data including information on the movement direction and movement amount of the player character is detected.

  Next, in step S53, the CPU 36 calculates the first position coordinates after the movement when moving from the current position based on the operation input. The current position is acquired from the player character position data area 96.

  In step S55, the CPU 36 determines whether there is correction from the external force object. In this embodiment, in the non-player object control process in step S3 (FIG. 12), as described above, a process for determining whether to perform correction using an external force object and determining a correction value is executed. In step S55, for example, it is determined whether movement correction data or the like is output to a predetermined area of the data storage area 72 by the non-player object control process.

  If “NO” in the step S55, that is, if the correction by the external force object is not performed, in a step S57, the CPU 36 moves the player character to the first position coordinate based on the operation input calculated in the step S53. . At this time, the moving speed is determined by a vector determined by the position coordinates of the current position and the position coordinates after the movement, and the player character moves in the game space at the moving speed. When step S57 ends, the process returns to step S7 in FIG.

  On the other hand, if “YES” in the step S55, that is, if the correction by the external force object is performed, the CPU 36 performs the second movement after the movement in the case of moving from the current position based on the movement correction data in the step S59. Calculate the position coordinates. When the player character is present at a position where an external force is applied from a plurality of external force objects and movement correction data for each of the plurality of external force objects is output, the player character is moved based on the correction data. The second position coordinates are calculated.

  Subsequently, in step S61, the CPU 36 calculates the third position coordinates after the movement in the case of actually moving based on the first position coordinates and the second position coordinates. If a plurality of second position coordinates are calculated, the third position coordinates are calculated based on the first position coordinates and all the second position coordinates. That is, in this case, the third position coordinate moved according to the combined vector of the movement vector based on the plurality of operation correction data and the movement vector based on the operation input is calculated.

  In step S63, the CPU 36 moves the player character to the third position coordinate. When step S63 ends, the process returns to step S7 in FIG.

  According to this embodiment, when the position of the player character and the position of the external force object are within a predetermined distance range, the operation input of the player character is corrected by repulsive force or attractive force based on the inner surface parameter indicating the inner surface of the player character. Is moved away from the external force object or brought close to the external force object, so that the internal characteristics of the player character can be reflected. Therefore, the invisible inner surface such as the character and mental state of the player character can be expressed by the action. In addition, it is difficult for the player to perform his / her own operation, and he / she can feel that he / she is not operating as he / she desires.

  Further, since the player can guess the inner surface of the player character from the action of the player character that does not follow the operation input of the player, for example, it is possible to enjoy a new game development using it as a keyword. For example, if it is found from the movement that the player character is not good at cats, it is possible to develop such that the cat is dismissed and moved quickly by taking a dog, for example, a cat's natural enemy.

  Further, since the inner surface information is stored for each type of player character, depending on the type of the player character, repulsive force or attractive force may or may not be applied when approaching the external force object. It is possible to express the characteristics and personality of the different inner faces, and to enhance the fun of action games that tend to be monotonous.

  In the above-described embodiment, in the control process of the non-player object, it is determined whether or not the player character exists within a predetermined distance range from the external force object existing in the game space. However, in another embodiment, in the player character control process, it may be determined whether or not an external force object exists within a predetermined distance from the player character. An example of the operation of the player character control process of another embodiment is shown in FIG. In the case of this other embodiment, in the non-player object control process (FIG. 13), for example, the process of step S21 is executed.

  In the first step S81 in FIG. 15, the CPU 36 detects the operation input, and in step S83, calculates the first position coordinates when the movement is performed based on the operation input. In step S85, the CPU 36 determines whether or not an external force object exists in the game space or in a range displayed as a game image. If “NO” in the step S85, the CPU 36 moves the player character to the first position coordinates as it is in a step S87, and ends the control process of the player character.

  On the other hand, if “YES” in the step S85, the CPU 36 refers to the inner surface parameter of the player character in a step S89, and corresponds to the inner surface of the player character among the external force objects existing in the game space or the like. It searches for an external force object that applies an external force. In step S91, the CPU 36 determines whether there is an external force object that causes an external force to act on the player character to cause correction. If “NO” in this step S91, that is, if all the external force objects extracted in the step S85 are neither favorite objects or disliked objects of the player character, correction by external force is not performed, Proceed to step S87.

  On the other hand, if “YES” in the step S91, that is, if there is an external force object that is an object that the player character likes or dislikes, in a subsequent step S93, the CPU 36 determines whether the player character and the external force object are Calculate the distance. If there are a plurality of external force objects that cause correction, one is selected and the distance to the external force object is obtained.

  Subsequently, in step S95, the CPU 36 determines whether or not the external force object exists within a predetermined distance range from the player character based on the calculated distance. In other embodiments, the predetermined distance range may be set in the same manner as in the above-described embodiments, for example. That is, the predetermined distance range is an area surrounded by the outer periphery D1 having the first distance from the position of the player character, and is surrounded by the outer periphery D1 and the inner periphery D2 having the second distance smaller than the first distance. And a second region surrounded by the inner periphery D2. The magnitude of the external force to be applied, that is, the correction value based on the external force, may be changed according to the distance between the player character and the external force object in the same manner as in the above-described embodiment. For example, the first area 104 may be increased as it approaches the inner circumference D2, and the second area 106 may be set to a constant value.

  If “YES” in this step S95, the CPU 36 determines whether or not the external force object is a disliked object or a favorite object in a succeeding step S97. If “YES” in this step S97, that is, if the external force object is an object disliked by the player character, the CPU 36 corrects by repulsive force according to the distance between the player character and the external force object in a step S99. A value is determined, and movement correction data for moving away from the external force object is generated. On the other hand, if “NO” in the step S97, that is, if the external force object is a favorite object, the CPU 36 calculates a correction value by attractive force in accordance with the distance between the player character and the external force object in a step S101. The movement correction data that is determined and approaches the external force object is generated.

  When step S99 or step S101 ends, the process proceeds to step S103. If “NO” in the step S95, that is, if the external force object does not exist within a predetermined distance range from the player character, the process proceeds to a step S103.

  In step S103, the CPU 36 determines whether or not the processing has been completed for all the external force objects determined to cause correction corresponding to the inner surface in step S91. If “NO” in the step S103, the process returns to the step S93 to repeat the processes for the remaining external force objects.

  On the other hand, if “YES” in the step S103, the CPU 36 calculates a second position coordinate in the case where the current position is moved based on the correction value in a step S105. In addition, when correct | amending by several external force object, each 2nd position coordinate at the time of moving based on each correction value is calculated. Subsequently, in step S107, the CPU 36 calculates third position coordinates to be actually moved based on the first position coordinates and the second position coordinates. In addition, when correct | amending by a some external force object, a 3rd position coordinate is calculated based on a 1st position coordinate and a some 2nd position coordinate. In step S109, the CPU 36 moves the player character to the third position coordinates, and ends the player character control process.

  In each of the above-described embodiments, the inner surface parameter data is preliminarily registered as indicating the inner surface such as the personality of each player character. However, the inner surface parameter data is set in accordance with the progress or state of the game. You may do it. In this case, when the player character approaches the external force object, repulsive force or attractive force may or may not work depending on the situation or state of the player character, so that the fun of the game can be increased.

  For example, the inner surface parameter is set when an experience or event that affects the inner surface of the player character occurs in the progress of the game or when the inner character is affected. As a specific example, when a player character experiences biting by a dog, the dog is set as an object that the player character dislikes, and then a repulsive force is applied when approaching the dog. For example, when the vitality (life) of the player character is reduced, food that restores vitality is set to a favorite object, and then an attractive force is applied when approaching the food.

  In addition, the inner surface parameter may be given strength based on the frequency or degree of the experience that affects the inner surface. That is, for example, the magnitude of the correction value by the external force, the size of the predetermined distance range where the external force acts, or the like may be changed according to the number of times the dog has been attacked, the degree of damage, or the degree of decrease in vitality. Good. Thereby, a change in the inner surface of the player character in accordance with the progress status or state of the game can be expressed by the movement.
