  However, all of the above-described conventional techniques change the performance of the moving body, and even a player (advanced player) with high operation skill cannot travel beyond the performance of the moving body. In other words, when a competitive game is played by a plurality of players, a player (beginner) with low operation skill has the pleasure of playing an incandescent game with an advanced person, but an advanced person may demonstrate his own operation skill. There was a problem that the game was not satisfactory and lacked in satisfaction.

  Therefore, a main object of the present invention is to provide a novel game program and game apparatus.

  Another object of the present invention is to provide a game program and a game apparatus that can sufficiently enjoy a game even when players having different operation skills play.

  The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses, supplementary explanations, and the like indicate correspondence with embodiments to be described later in order to help understanding of the present invention, and do not limit the present invention.

  The invention of claim 1 is a game program for a game device for playing a competitive game in which a plurality of moving bodies operated by each of two or more players compete on a course provided in a virtual game space, the game device comprising: Relative position detecting means for detecting the relative position of each moving body in all moving bodies, and a change for changing at least one of the size of each moving body and the course width according to the relative position detected by the relative position detecting means It functions as a means.

  In the first aspect of the present invention, the game program is stored or loaded in a game device (12: reference numeral corresponding to the embodiment. The same applies hereinafter), and a plurality of moving bodies operated by each of two or more players. A competitive game is executed in which (72) is competed on a course provided in the virtual game sky, and the player plays the competitive game. This game program causes the game apparatus to function as relative position detecting means (36, S29, S31, S33, S41, S65, S89, S91, S93, S101) and changing means (36, S49, S71, S109). The relative position detecting means detects the relative position of each moving body in all the moving bodies. The changing means changes at least one of the size of each moving body and the width of the course according to the relative position detected by the relative position detecting means. For example, by changing the size of the moving body, changing the width of the course, or changing both, the relative position of the moving body to the width of each course (the width that the moving body can pass) The size is changed.

  According to the first aspect of the present invention, since at least one of the size of the moving body and the width of the course is changed, for example, for a moving body that is ahead of other moving bodies, The degree of difficulty of the game can be increased by deforming so that the size of the game becomes larger. In other words, if an advanced player and a beginner play simultaneously, the advanced player will play a more difficult game, while the beginner will play a relatively easy game and compete with the advanced player. Therefore, regardless of the level of the player's operation skill, it is possible to enjoy the satisfaction and fun of the game.

  The invention of claim 2 is dependent on claim 1, and the changing means sets the moving body so that the higher the order determined by the relative position detected by the relative position detecting means, the larger the moving body as compared with the other moving bodies.

That is, the difficulty level of the game of the player who operates the moving body having a higher rank can be increased, and the advanced player can demonstrate his / her operation skill and enjoy the satisfaction and fun of the game.

  The invention according to claim 3 is dependent on claim 1, and the higher the order determined by the relative position detected by the relative position detecting means, the higher the order that the changing means passes, the course width that the moving body passes is that other moving bodies pass. A course deforming means for deforming so as to be narrower than the course width to be performed.

  In the third aspect of the invention, the course deformation means (36, S109) is such that the higher the order detected by the relative position detection means is, the larger the course width that the moving body passes is compared to the course width that other moving bodies pass. Deform to narrow.

  According to invention of Claim 3, even if it changes a course width | variety, the magnitude | size of the mobile body with respect to a course width | variety can be changed, and the difficulty of a game can be changed.

  The invention of claim 4 is dependent on any one of claims 1 to 3, wherein a plurality of passing points are set in the course, and the relative position detecting means determines the relative position of each moving body in all moving bodies for each passing point. To detect.

  In the invention of claim 4, a plurality of passing points are set in the course, and the relative position detecting means detects the relative position of each moving body in all moving bodies for each passing point.

  According to invention of Claim 4, since the relative position of each moving body is detected for every passing point, the magnitude | size of each moving body with respect to a course width | variety can be changed for every passing point. That is, since the size of each moving body with respect to the course width can be changed according to the relative position of the moving body that changes as the game progresses, the competitive game does not become monotonous.

  The invention of claim 5 is dependent on claim 4 and includes a passing time detecting means for detecting a passing time for each moving body to pass the passing point, and of the passing time detected by the passing time detecting means, the passing point at the head. The passage time storage means for storing only the passage time when passing, the head judgment means for judging whether or not the passage point has been passed at the head, and when the head judgment means determines that the head has passed at the beginning, it is set in advance. Set the deformation rate and set the deformation rate based on the difference between the head passage time stored in the passage time storage means and its own passage time when it is determined by the head discrimination means that it has not passed at the head. It further functions as a deformation rate setting means.

  In the invention of claim 5, the passage time detecting means (36, S31, S41, S91, S101) detects the passage time when each moving body passes the passage point. For example, the passing time is an elapsed time from the starting point of the course to the passing point. The passage time storage means (36, S41, S101) stores only the passage time when passing through the passage point at the head among the passage times detected by the passage time detection means. The head discriminating means (36, S29, S89) discriminates whether or not the passage point is passed at the head. That is, when it is determined by the head determination means that the passage point is passed at the head, the passage time is stored by the passage time storage means.

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 or the like is mounted on the optical disk drive 16. A plurality of (four in the first 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 the cable 24. In the first embodiment, a maximum of four controllers 22 can be connected to the video game apparatus 12.

  The controller 22 is provided with an operation unit (operation switch) 26 on its upper surface, lower surface, or side surface. The operation unit 26 includes, for example, two analog joysticks, one cross key, a plurality of button switches, and the like. One analog joystick is used to input the moving direction and / or moving speed or moving amount of a player object (moving image object that can be operated by the player by the controller 22) according to the tilt amount and direction of the stick. Other analog joysticks control the movement of the virtual camera according to the tilt direction. The cross switch is used to instruct the moving direction of the player object instead of the analog joystick. The button switch is used to instruct the movement of the player object, is used to switch the viewpoint of the virtual camera of the three-dimensional image, and is used to adjust the movement speed of the player object. The button switch further controls, for example, menu selection and pointer or cursor movement.

  In the first 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). In addition, the specific configuration of the operation unit 26 of the controller 22 is not limited to the configuration of the first embodiment, and can be arbitrarily modified. For example, only one analog joystick may be used or not used. The cross switch may not be used.

  One or more (two in this first embodiment) 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 read from the optical disc 18 or stores game data (game result data or intermediate data) of a game played using the game system 10 ( It is used for saving.

  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. Therefore, for example, a game image of a three-dimensional (3D) video game is displayed on the screen of the color television (monitor) 34, and stereo game sounds such as game music and sound effects are output from the left and right speakers 34a.

  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 object (player object) can be moved in different directions, or the user's viewpoint (camera position) in the three-dimensional (3D) game world 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 36 or the computer functions as a game processor, and a memory controller 38 is connected to the CPU 36 via a bus. The memory controller 38 mainly controls writing and reading of the main memory 40 connected via the bus under the control of the CPU 36. A GPU (Graphics Processing Unit) 42 is connected to the memory controller 38.

  The GPU 42 forms part of the drawing means, and is constituted by, 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 three-dimensional (3D) game image. That is, the geometry unit 44 is a rotation of various objects 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) to 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 a part of the main memory 40, and these may be provided inside the GPU 42.

  The memory controller 38 is also connected to an audio RAM (hereinafter referred to as “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 (not shown) stored in the main memory 40 or uses sound waveform data (not shown) written in the ARAM 54 so as to be necessary for the game. Audio data corresponding to sound, voice or music is generated.

  The memory controller 38 is further connected 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 connected to the video game apparatus 12, and gives an operation signal or operation 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 connects 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 program storage area 402 and a data storage area 404. The program storage area 402 stores a game program for a competitive game. This game program includes a game main processing program 402a, an image generation program 402b, an image display program 402c, an operation information acquisition program 402d, a coordinate position calculation program 402e, a point passage determination program 402f, a point passage time detection program 402g, and an object deformation rate calculation. The program 402h, the object deformation rate setting program 402i, the object deformation program 402k, the object movement program 402m, and the like.

  The game main process program 402a is a program for executing the main process of the competitive game of this embodiment. The image generation program 402b is a program for generating a virtual three-dimensional space such as a virtual game space and generating a game image including a player object, a non-player object, a background object, and the like existing in the virtual three-dimensional space. is there.

  Here, the player object refers to a moving image object that moves in a virtual three-dimensional space by an operation of a player (including a computer player). A non-player object refers to an object that moves according to a program without being operated by a player. The background object is an object related to the background such as a wall, a floor (ground), a pillar, or a tree. A competition game course is formed by such an arrangement of background objects.

  The image display program 402c is a program for displaying on the monitor 34 a game image generated by the execution of the image generation program 402b. The operation information acquisition program 402d is a program for acquiring operation information (operation input) by the player, and detects operation data (operation signal) from the controller 22 input via the controller I / F 56 to obtain data. Store in the storage area 404. The coordinate position calculation program 402e is a program for calculating the position coordinates (three-dimensional coordinates) of the moved player object in accordance with the operation data acquired by the operation information acquisition program 402d.

  The point passage determination program 402f is a program for determining whether or not the player object has passed a passage point of a competitive game course provided in the three-dimensional virtual space, based on the position coordinates calculated by the coordinate position calculation program 402e. It is. The point passing time detection program 402g is a program for detecting the time when the player object passes the passing point of the course of the competitive game and the information (for example, the number) of the passing point. The point passing time storage program 402h is a program for storing the elapsed time of the player object that has passed the passing point of the course of the competitive game first (at the top) in association with the player object.

  The object deformation rate calculation program 402i calculates its deformation rate (for example, enlargement rate) based on the passing time of the player object that has passed the passing point at the beginning and the passing time of the player object that has passed the passing point. It is a program. In the first embodiment, the player object is formed in a rod shape, and the enlargement ratio means a ratio of enlarging (longening) the length of the player object in the longitudinal direction.

  The object deformation rate setting program 402j is a program for setting the deformation rate (enlargement rate) of the player object that has passed the passing point at the head according to a predetermined condition. Here, the predetermined condition is a condition that can be arbitrarily set by the programmer or developer of this competitive game. In the first embodiment, the player object that has passed the passing point at the beginning passes another player object in one section. This is a condition of whether or not they are separated from each other (section determined by two consecutive passing points).

  However, as described above, since the predetermined condition can be set arbitrarily, it is not necessary to be limited to this. Therefore, for example, a condition may be set as to whether or not the player object that has passed the passing point at the beginning has passed one section within a certain time (for example, 8 seconds).

  The object deformation program 402k is a program for deforming the size of the player object according to the deformation rate (enlargement rate) calculated or set by the object deformation rate calculation program 402i or the object deformation rate setting program 402j.

  The calculation of the enlargement ratio of the player object, the setting of the enlargement ratio, and the deformation according to the enlargement ratio will be described in detail later.

  The object motion program 402m changes the posture of the player object (in this first embodiment, “rotates”) and arranges (moves) the player object at the coordinate position calculated by the coordinate position calculation program 402e. It is a program.

  Although illustration is omitted, in the program storage area 402, a game music reproduction program for outputting a sound (music) necessary for a virtual game (competitive game) executed by the video game apparatus 12, data in the middle of the game, and results A backup processing program for storing (backup) game data such as data is also stored.

  The data storage area 404 stores data such as image data 404a, operation data 404b, coordinate data 404c, and a transit time table 404d.

  The image data 404a is data (polygon data, texture data, etc.) for generating a game image. The operation data 404b is operation data acquired according to the operation information acquisition program 402d. The coordinate data 404c is position coordinate data calculated according to the coordinate position calculation program 402e. The passage time table 404c is table data created based on the passage time detected according to the point passage time detection program 402g and the number of passage points (see FIG. 7).

  Although not shown in the figure, the data storage area 404 also stores sound data about music (BGM) played during the game and sound (music) such as sound effects. The data storage game 404 stores (temporarily stores) game data, flag data, and the like generated as the competitive game progresses.

  FIG. 4A shows an example of a game screen 70 when three players play the competitive game of the first embodiment. This game screen 70 is displayed on the monitor 34 shown in FIG. Referring to FIG. 4A, in this game screen 70, the screen for 1P is displayed at the upper left, the screen for 2P is displayed at the upper right, the screen for 3P is displayed at the lower left, and the screen The lower right of is blanked. However, when a competitive game is played by four players, the lower right area blanked in FIG. 4A is a 4P screen.

It becomes.

  In this competitive game, a rod-like moving body (player object) 72 (72a, 72b, 72c) is moved in the traveling direction in accordance with the operation of a player (including a computer) and aims at the goal of the course. As shown in FIG. 4B, the moving body 72 rotates (rotates) in a predetermined direction (for example, rightward) with the center as an axis. That is, the position of the moving body 72 on the course is changed according to the player's operation, and its posture (orientation) is changed by its own rotation. That is, the player moves the moving body 72 so as to advance on the course while watching the posture of the moving body 72. For example, in FIG. 4B, the right direction in the drawing is the traveling direction of the moving body (the direction toward the goal).

  In a competitive game, for example, each time the moving body 72 collides with an obstacle such as a wall, its life force (LP) is subtracted, and when LP becomes 0, the previous passing point (or start point). Moved (returned) to Therefore, it is possible to win the competition game by moving the moving body 72 according to the course and making a goal at the head without colliding as much as an obstacle.

  In general, in such a competitive game, when an advanced player and a beginner enjoy the game at the same time, there is a difference between a mobile body operated by the advanced player and a mobile body operated by the beginner. Therefore, the performance of a moving object that is delayed is improved. For example, in a moving body with a low rank (a moving body operated by a beginner), the speed and acceleration are increased. Thereby, the difference in the distance between the moving body having a higher rank (moving body operated by an advanced player) and the moving body having a lower rank is reduced, and the moving bodies (players) compete with each other to make the game more incandescent. It is like that.

  However, if the performance of the moving body itself is changed in this way, even if the operation capability is high, it is not possible to travel at a speed higher than that of the moving body. As a result, beginners can enjoy the game because they can easily compete with the advanced player even if the operation skill is low, but the advanced player cannot demonstrate his own operation ability, There is a problem of lack of satisfaction and fun.

  Therefore, in the first embodiment, the difficulty of the game (difficulty level) is not changed by changing (deforming) the size of each moving body with respect to the course width (course width) instead of changing the performance of the moving body. ), So that advanced and beginners can enjoy the game at the same time and get enough satisfaction and fun. In other words, advanced players can get fun and satisfaction by playing games in more difficult situations and winning the competition. On the other hand, a beginner can play a game in a relatively simple situation and compete with an advanced player, or sometimes win the competition, and enjoyment and satisfaction can be obtained.

  In the first embodiment, a passing point is provided in advance in the course, and the moving body 72 that has passed the passing point at the beginning is deformed at a predetermined enlargement ratio, and the second and subsequent moving bodies 72 are moving bodies that have passed at the beginning. The enlargement ratio is calculated based on the difference from 72 (time difference), and is deformed at the calculated enlargement ratio. In other words, the relative positions of the moving bodies are detected for each passing point, and each of the moving bodies 72 is deformed at an enlargement ratio corresponding to the positional relationship. Hereinafter, a specific description will be given with reference to FIGS. 5 and 6.

  FIG. 5 shows a state in which the moving bodies 72a, 72b, and 72c are competing in a course having a shape in which the S-shape is reversed left and right. In this course, four passing points P1, P2, P3, and P4 are provided between the start and the goal. As shown in FIG. 5, when the moving body 72a passes the passing point P1, the moving body 72a is the head, the moving body 72c is the second, and the moving body 72b is the tail.

  In this case, the length of the moving body 72a passing through the passing point P1 at the head is deformed at a predetermined enlargement rate, and the lengths of the moving body 72b and the moving body 72c are the enlargement rate based on the time difference from the moving body 72a. Transformed. Here, as shown in FIG. 6 (A1), the size (length) of all the moving bodies 72 (72a, 72b, 72c) is 50% at the start point. As shown in FIG. 6 (A2), this shows the ratio when the length of the moving body 72 when passing through the passing points (P1, P2, P3, P4) at the head is 1 (100%). . That is, when passing through the passing point at the head, the length of the moving body 72 is increased (enlarged) from 50% to 100%. Accordingly, the size of the moving body 72 with respect to the course width is increased, and the moving body 72 easily collides with an obstacle such as a wall. As a result, the difficulty of the game for the player who operates the moving body 72 increases. .

  However, although illustration is omitted, when the difference between the moving body 72 that has passed the passing point at the head and the other moving body 72 is one or more sections, that is, when a predetermined condition is satisfied, the moving body The length of 72 is deformed to 120%. In other words, the difficulty level of the game is made higher than when passing at the top.

  Thus, when passing through the passing point at the head, the length of the moving body 72 is deformed at a preset ratio. At this time, a different enlargement ratio is set depending on whether or not the other moving body 72 is separated by one section or more.

  Further, as shown in FIG. 5, the moving body 72b and the moving body 72c do not pass the passing point P1 at the head. In this way, in the moving body 72 that does not pass the passing point at the head, the length of the moving body 72 based on the passing time that the leading moving body 72 passes the passing point and the passing time that the head moving body 72 passes the passing point. The enlargement ratio is determined. Specifically, as shown in FIG. 6 (B1), when passing the passing point with a delay of 0 to 8 (seconds) from the beginning, it is linearly expanded between 50% and 100%. A rate is calculated. In the first embodiment, the enlargement ratio is calculated according to Equation 1. However, in Equation 1, Tf is the passing time of the leading mobile body 72, and Tx is its own passing time. Also, as shown in FIG. 6 (B2), the deformation rate is determined to be 50% when it is delayed for 8 seconds or more from the head. In other words, the size is not less than the size of the starting point.

  Note that the value of 8 seconds is a value set by a game programmer or developer, and can be variably set depending on the size of the map (the length of the course), the moving speed of the moving body, and the like.

[Equation 1]
Enlargement ratio (%) = 100− (Tx−Tf) ÷ 8 × 50 (Tx−Tf <8)
Magnification rate (%) = 50 (Tx−Tf ≧ 8)
In the first embodiment, when the size of the moving body 72 is changed using the size of the moving body 72 at the start point as a default, the size of the moving body 72 is enlarged. The deformation rate is called the enlargement rate. However, the size (length) of the moving body 72 appears to be reduced when it is once enlarged and then enlarged at an enlargement rate smaller than the enlargement rate.

  FIG. 7 is an illustrative view showing one example of the above-described passage time table 404d. Referring to FIG. 7, in passage time table 404d, passage points and passage times are described corresponding to object names. In the object name column, the name (or identification information) of the player object (moving body 72) is described. Although illustration is omitted, the names of the 1P moving body 72, the 2P moving body 72, the 3P moving body 72, and the 4P moving body 72 are described in order from the top of the passing time table 404d. In the passage point column, the latest passing point number among the passing points that the corresponding mobile object 72 has already passed, that is, the number of the passing point closer to the goal is described. The passage time column describes the elapsed time from the start point to the passage point only when the passage point is passed at the head. Therefore, the passing time is not described for the moving body 72 that does not pass the passing point at the head. In FIG. 7, a bar (horizontal bar) is described to express that the passing time is not described.

  That is, in the passing time table 404d shown in FIG. 7, the (2P) moving body 72 of the second object passes through the passing point P3 at the head, and the elapsed time (passing time) at that time is 21 seconds 36. Indicated. Further, it is indicated that the moving bodies 72 corresponding to the first object, the third object, and the fourth object pass through the passing point P2, but have not reached the passing point P3.

  Thus, if the passing time table 404d is provided, the first passing time is detected only by detecting the passing time when the second and subsequent player objects (moving bodies 72) pass the passing point. Based on the difference, the length of the moving body 72 can be deformed. Further, when the leading mobile body 72 passes the passing point, it is easy to determine whether or not the leading mobile body 72 is separated from the other mobile bodies 72 by one section or more by referring to the transit time table 404d. Can be judged. Therefore, the enlargement ratio for the leading mobile body 72 can also be set easily.

  FIG. 8 is a flowchart showing the entire process of the competitive game executed by the CPU 36 shown in FIG. Referring to FIG. 8, when CPU 36 starts the entire process of the competitive game, first, in step S1, an initial game screen is set. Here, a part of the course including the starting point of the competing course is displayed on the screen, and the moving body 72 participating in the competitive game is displayed on the screen so as to be arranged at the starting point. However, as described above, the screen of the monitor 34 is divided and displayed according to the number of players who play the competitive game.

  Prior to the start of the competitive game, the player selects the number of players to play, the moving body 72 to be operated, and the course to be competed.

  In the subsequent step S3, the elapsed time is started. That is, a timer (not shown in FIG. 2) is started. Next, in step S5, each object control process is executed. That is, the object control process shown in FIGS. 9 and 10 described later in detail is executed for each player object (moving body 72). In step S7, a game screen display process is executed.

  In step S9, it is determined whether or not the game is over. That is, it is determined whether an instruction to end the game is input by the player or the game is over. If “NO” in the step S9, that is, if the game is not ended, the process returns to the step S5 as it is. On the other hand, if “YES” in the step S9, that is, if the game is ended, the entire process of the game is ended.

  FIG. 9 and FIG. 10 are flowcharts showing object control processing executed for each player object (moving body 72) in step S5 of FIG. That is, the object control process is executed in parallel for each moving body 72. In the following, only the object control processing for one moving body 72 of interest will be described, but the moving body 72 of interest may be referred to as “the moving body 72”.

  Referring to FIG. 9, when the object control process is started, it is determined whether or not there is operation data in step S21. That is, the CPU 36 refers to a controller buffer (not shown) provided in the controller I / F 56 to determine whether operation data has been input.

  If “NO” in the step S21, that is, if there is no operation data, the process directly proceeds to a step S51 shown in FIG. On the other hand, if “YES” in the step S21, that is, if there is operation data, the coordinate after movement is calculated based on the operation data in a step S23. Specifically, the movement direction and movement amount of the moving body 72 are calculated from the inclination direction and the inclination amount of the joystick indicated by the operation data, and after the movement from the calculated movement direction and movement amount and the current position coordinates. Calculate the position coordinates.

  In a succeeding step S25, it is determined whether or not the passing point is passed. That is, it is determined whether or not the position coordinates after the movement calculated in step S23 pass the passing point. If “NO” in the step S25, that is, if the passing point is not passed, the process proceeds to a step S51 as it is. On the other hand, if “YES” in the step S25, that is, if the passing point is passed, the passing point number that has passed is stored in a buffer area (not shown) of the main memory 40 (temporary storage) in a step S27. )

  Subsequently, in step S29, it is determined whether or not there is an object (moving body 72) that has already passed the book (the relevant) passing point. That is, it is determined whether or not the vehicle passes through the main passing point. If “YES” in the step S29, that is, if the main passing point is not passed at the head, it is determined that there is a moving body 72 that has already passed the main passing point, and the timer is referred to in a step S31. The current transit time Tx is acquired. Next, in step S33, a time difference ΔT (Tx−Tf) from the leading passage time Tf is calculated.

  In step S35, it is determined whether the time difference ΔT is 8 seconds or more. If the time difference ΔT is 8 seconds or more, in step S37, the enlargement ratio is set to 50%, and the process proceeds to step S49 shown in FIG. On the other hand, if “NO” in the step S35, that is, if the time difference ΔT is less than 8 seconds, an enlargement ratio is calculated according to a predetermined arithmetic expression (Equation 1) on the basis of the time difference ΔT in a step S39, and a step S49 is performed. Proceed to

  However, if “NO” in the step S29, that is, if the main passing point is passed at the head, it is determined that there is no moving body 72 that has already passed the main passing point, and the passing time Tf is determined in the step S41. Is detected (acquired) and stored. That is, the passage time Tf is acquired from the timer, and the passage time Tf is described in the corresponding column of the passage time table 404d. In a succeeding step S43, it is determined whether or not it is separated from another object (the moving body 72) by one section or more. Here, the passage time table 404d is referred to, and the determination is made from the passage point number.

  If “NO” in the step S43, that is, if the moving object 72 is not separated by one section or more, the enlargement ratio is set to 100% in a step S45, and the process proceeds to the step S49. On the other hand, if “YES” in the step S43, that is, if it is separated from another moving body 72 by one section or more, the enlargement ratio is set to 120% in a step S47, and the process proceeds to the step S49. However, in step S47, it may be set linearly between 100% and 120% depending on the passage time of one section.

  As shown in FIG. 10, in step S49, the object (moving body 72) is deformed in the longitudinal direction in accordance with the set or calculated enlargement ratio. In the subsequent step S51, the posture is determined based on a predetermined rotation amount. In step S53, the object (moving body 72) is arranged on the map (course), the display area is updated, and the object control process is returned.

  The display area is updated so that the display area is arranged at a predetermined position on the screen (for example, a position shifted to the opposite side of the center or the traveling direction). This is to make it easier for the player to see his or her player object (moving body 72) or to see the course in the traveling direction.

  According to the first embodiment, when the relative position with respect to another moving body is detected for each passing point and the passing point is passed at the head, the moving body is deformed long, and the passing point is not passed at the head. Since it is deformed to a size smaller than the moving body that has passed at the top, the difficulty of the game can be increased as the passing point is passed faster. In other words, when an advanced player and a beginner play at the same time, the advanced player can play at a higher level of difficulty, and the beginner can play incandescent with the advanced player. Regardless of skill, you can enjoy the satisfaction and enjoyment of the game.

  In the first embodiment, when the passing point is passed at the head, a different enlargement ratio is set depending on whether or not a predetermined condition is satisfied. The enlargement ratio may be set. In such a case, the processing in steps S43 and S47 shown in FIG. 9 may be deleted.

  In the first embodiment, the passage point is passed after the second point, and when the time difference from the head is a certain time or more, a constant enlargement ratio is set. The enlargement ratio may be calculated according to a predetermined arithmetic expression without providing the above. In such a case, the processes in steps S35 and S37 shown in FIG. 9 may be deleted.

  Furthermore, in the first embodiment, by changing the length of the moving body, the difficulty level of the game of the player who plays at the same time is made different. However, the rotational speed of the moving body may be changed. . Even in this case, it can be said that the size of the moving body with respect to the course width is changed. In such a case, the rotational speed of the moving body may be increased as the passing time of the passing point is faster. For example, in a portion where the course width is relatively narrow, if the rotational speed of the moving body is high, it is difficult to measure the timing of rotation when passing through that portion, and there is a high possibility of colliding with the wall of the course. Because it becomes. In other words, when the rotational speed of the moving body is fast, the time for the relative size of the moving body to increase with respect to the course width increases. When the rotational speed of the moving body is slow, the relative position of the mobile body with respect to the course width. The time for increasing the size becomes shorter.

In the first embodiment, a video game system in which a video game apparatus and a monitor are separately provided has been described. However, it goes without saying that the present invention can also be applied to a game apparatus in which a monitor is provided integrally.
<Second embodiment>
The game system 10 of the second embodiment is the same as the first embodiment except that the rank of the moving body 72 is detected at regular intervals and the moving body 72 is deformed at an enlargement rate determined according to the rank. Therefore, the overlapping description will be omitted.

  For example, in the second embodiment, the distance to the goal of each moving body 72 is calculated at fixed time intervals, and the rank of each moving body 72 is determined. Although illustration is omitted, in the course as shown in FIG. 5 of the first embodiment, a virtual line (a set of points) passing through the center of the course is provided, and each point is a distance from the goal. Are stored in association with each other. However, the virtual line is not displayed on the monitor 34 as a game screen. The CPU 36 determines the point closest to the moving body 72 among the points constituting the virtual line as the position of the moving body 72, and determines the rank according to the distance from the goal to the position. Although not shown, the determined rank data (rank data) is stored (temporarily stored) in the buffer area of the main memory 40 and is rewritten every time the rank is determined.

  When the rank of the moving body 72 is determined, an enlargement ratio corresponding to the rank is set. For example, in a four-player game, the enlargement rate of the first-ranking (first) moving body 72 is set to 100%, the enlargement rate of the second-ranking moving body 72 is set to 80%, and the third-ranking moving body 72 is enlarged. The rate is set to 60%, and the enlargement rate of the fourth-place moving body 72 is set to 50%. In the three-player game, the enlargement rate of the first moving body 72 is set to 100%, the enlargement rate of the second moving body 72 is set to 80%, and the enlargement rate of the third moving body 72 is 50%. % Is set. Further, in the two-player game, the enlargement rate of the first-ranking mobile body 72 is set to 80%, and the enlargement rate of the second-ranking mobile body 72 is set to 50%.

  However, since the numerical values of these enlargement rates are merely examples, the developers and programmers of competitive games can arbitrarily set them. Further, an enlargement rate table corresponding to the number of players is stored in the main memory 40, and each table describes an enlargement rate value corresponding to the rank. These tables are stored in place of the transit time table 404d shown in the first embodiment, for example.

  Thus, the moving body 72 is deformed (the length in the longitudinal direction is deformed) in accordance with the enlargement ratio set in advance according to the order detected at regular intervals. Specifically, in the second embodiment, the CPU 36 executes the object control process shown in FIG. 11 in step S5 of the overall process shown in FIG. Although illustration is omitted, in the second embodiment, since the enlargement ratio is not determined based on the time difference ΔT from the head, the process of step S3 is deleted in the overall process shown in FIG. Here, the same processing as the object control processing shown in FIGS. 9 and 10 will be briefly described.

  Referring to FIG. 11, when CPU 36 starts object control processing, it is determined in step S61 whether there is operation data. If “NO” in the step S61, the process proceeds to a step S65 as it is. On the other hand, if “YES” in the step S61, the coordinate after movement is calculated based on the operation data in a step S63, and the process proceeds to the step S65.

  In step S65, the current rank of the moving body 72 is detected. The order detection method is as described above. In the next step S67, it is determined whether or not there is a change in the order. Here, the own rank temporarily stored in the main memory 40 (previous rank) is compared with the own rank detected in step S65 (current rank) to determine whether or not they are inconsistent with each other.

  If “NO” in the step S67, that is, if the previous ranking matches the current ranking, it is determined that there is no change in the ranking, and the process proceeds to a step S73 as it is. On the other hand, if “YES” in the step S67, that is, if the previous ranking and the current ranking do not coincide with each other, it is determined that there is a change in the ranking, and is temporarily stored in the main memory 40 in a step S69. Update ranking data. In step S71, the object is deformed in the longitudinal direction on the basis of an enlargement ratio determined in advance according to the rank, and the process proceeds to step S73. That is, in step S71, an enlargement rate table corresponding to the number of players is referred to, an enlargement rate corresponding to the rank is determined (set), and the moving body 72 is deformed according to the enlargement rate.

  As described in the first embodiment, since the object control process is executed in parallel for each moving body 72, only the change of its own rank is detected in step S65, and only its own rank is detected in step S69. As a result, all rankings can be updated.

  In step S73, the posture is determined based on a predetermined rotation amount. In step S75, the object (moving body 72) is placed on the map, the display area is updated, and the object control process is returned.

  As shown in FIG. 8, the process of step S5 is executed at regular time intervals (the scan time of the loop composed of steps S5, S7, and S9), and therefore according to the order detected at regular time intervals. The size of the moving body 72 with respect to the course width is deformed.

According to the second embodiment, since the length of the moving body 72 is deformed according to the order detected at regular intervals, the size of the moving body with respect to the course width can be deformed. Therefore, the same effect as the first embodiment can be obtained.
<Third embodiment>
The game system 10 of the third embodiment detects the relative position of the moving body 72 for each passing point, and deforms the course width according to the relative position, thereby deforming the size of the moving body with respect to the course width. Since other than that is the same as the first embodiment, a duplicate description is omitted.

  In the third embodiment, when a passing point is passed at the head, a preset reduction rate (multiplication rate) is set. This reduction ratio is a deformation ratio for deforming the width of the course (background object), and different values are set according to predetermined conditions, as in the first embodiment. The predetermined condition is the same as the condition described in the first embodiment. In the third embodiment, the reduction rate is set to 50% when passing the passing point at the head, and further, the reduction rate is set to 40% when a predetermined condition is satisfied. In the second and subsequent moving bodies 72, a reduction ratio calculated based on a time difference ΔT (Tx−Tf) from the head passage time is set. Specifically, the reduction ratio is calculated according to Equation 2. However, the reduction ratio when the default course width is 1 (100%) is calculated. In addition, when the time difference ΔT is 8 seconds or more, the reason why the course width reduction ratio is set to 100% is the same reason as that when the enlargement ratio is set to a constant value in the first embodiment.

[Equation 2]
Reduction ratio (%) = 50+ (Tx−Tf) ÷ 8 × 50 (Tx−Tf <8)
Reduction rate (%) = 100 (Tx−Tf ≧ 8)
In this way, by changing the course width in accordance with the set reduction rate according to Equation 2, the course width becomes narrower for the leading moving body 72.

  In the third embodiment, the course width is reduced on the basis of the default value of the course width. For convenience of explanation, the deformation rate is referred to as the reduction rate. However, if the course width is once reduced and then reduced at a reduction rate that is larger than the reduction rate, the course width appears to have increased.

  For example, FIG. 12 shows an example of a game screen 70 when four players play a competitive game. In this game screen 70, display areas for 1P, 2P, 3P, and 4P are provided, and each display area is arranged as described in the first embodiment. In the game screen 70 shown in FIG. 12, the 2P moving body 72b passes a certain passing point at the head, the second 1P moving body 72a passes the passing point, and the third 4P moving body 72d passes. A state is shown in which the fourth moving body 72c passes through the passing point and passes through the passing point. That is, the course width through which the moving body 72 that has passed through the passing point earlier passes is narrower than the course width through which the other moving bodies 72 pass.

  In FIG. 12, the course is formed by a region sandwiched between upper and lower walls indicated by hatched portions. Therefore, the course width is determined by the size of the upper and lower walls.

  Although illustration is omitted, when an obstacle exists on a course (default course) prepared in advance, the obstacle is arranged on the course after the course width is narrowed. . In this respect, the course width can be said to be a width through which the moving body 72 can pass.

  In such a third embodiment, the object deformation rate calculation program 402i stored in the main memory 40 is based on the passing time of the player object that has passed the passing point at the beginning and the passing time that the player object has passed the passing point. This is a program for calculating the reduction ratio of the course width through which it passes.

  In the third embodiment, the object deformation rate setting program 402j stored in the main memory 40 sets the reduction rate of the course width through which the player object that has passed the passing point at the beginning passes according to a predetermined condition. It is a program.

  Furthermore, in the third embodiment, the object deformation program 402k stored in the main memory 40 corresponds to the player object corresponding to the reduction rate calculated or set by the object deformation rate calculation program 402i or the object deformation rate setting program 402j. This is a program for changing the course width.

  Since the other programs are the same as those described in the first embodiment, a duplicate description is omitted.

  Specifically, in the third embodiment, the CPU 36 executes the object control process shown in FIGS. 13 and 14 in step S5 of the overall process shown in FIG. The object control process of the third embodiment is almost the same as the object control process of the first embodiment, and therefore the same process will be briefly described.

  Referring to FIG. 13, when starting the object control process, CPU 36 determines whether or not there is operation data in step S81. If “NO” in the step S81, the process proceeds to a step S111 shown in FIG. On the other hand, if “YES” in the step S81, the coordinates after the movement of the moving body 72 are calculated based on the operation data in a step S83. In the next step S85, it is determined whether or not the passage point has been passed.

  If “NO” in the step S85, the process proceeds to a step S111 as it is. However, if “YES” in the step S85, the passing point number that has passed is temporarily stored in a step S87. In step S89, it is determined whether or not there is an object (moving body 72) that has already passed the book (the relevant) passing point.

  If “YES” in the step S89, the current passing time Tx is obtained from the timer in a step S91, and a time difference ΔT from the leading passing time Tf is calculated in a step S93. In step S95, it is determined whether or not the time difference ΔT is 8 seconds or more. If “YES” in the step S95, the reduction ratio is set to 100% in a step S97, and the process proceeds to a step S109 shown in FIG. However, if “NO” in the step S95, a reduction ratio is calculated by a predetermined arithmetic expression (Equation 2) based on ΔT in a step S99, and the process proceeds to a step S109.

  On the other hand, if “NO” in the step S89, the passing time Tf is acquired and stored in a step S101, and it is determined whether or not one or more sections are separated from the other moving body 72 in a step S103. If “NO” in the step S103, the reduction ratio is set to 50% in a step S105, and the process proceeds to the step S109. However, if “YES” in the step S103, the reduction ratio is set to 40% in a step S107, and the process proceeds to the step S109.

  As shown in FIG. 14, in step S109, the course width is deformed based on the reduction ratio. In step S111, the posture is determined based on a predetermined rotation amount. In step S113, the object (moving body 72) is arranged on the map, the display area is updated, and the object control process is returned. To do.

  According to the third embodiment, since the course width becomes narrower as the moving body passes through the passing point earlier, the size of the moving body with respect to the course width can be changed, and the same effect as the first embodiment. Can be obtained.

  In the third embodiment, when the passage point is passed at the head, different reduction ratios are set depending on whether or not a predetermined condition is satisfied. The reduction ratio may be set. In such a case, the processes in steps S103 and S107 shown in FIG. 13 may be deleted.

  Further, in the third embodiment, when the passage point has passed through the second and subsequent points, and when the time difference from the head is a certain time or more, a constant reduction rate is set, this limit value The reduction ratio may be calculated according to a predetermined arithmetic expression without providing the above. In such a case, the processes in steps S95 and S97 shown in FIG. 13 may be deleted.

  Further, although detailed explanation is omitted, as in the case of the second embodiment, a table of course width reduction ratios according to ranks is prepared, and ranks are determined at fixed time intervals. The course width may be changed according to the conditions.

  In the above-described embodiment, only the moving body is deformed or only the course width is deformed. However, both the moving body and the course width may be deformed.
