Description

  The present invention relates to a game, such as a drive game (car racing game), in which the movement of a moving body on a running course set in a virtual space is represented by an image on a monitor, and is particularly fixed to the moving body. The present invention relates to a three-dimensional game apparatus in which a realistic running mode is expressed by displaying a view field image from a viewpoint on a monitor, and a program thereof.

  Conventionally, a driving game is known in which a traveling course is set in a virtual two-dimensional or three-dimensional space, and an automobile object (own vehicle) that is a moving body operated by a player on the traveling course is driven. Yes.

  This type of drive game is provided with operating means such as a handle for adjusting the moving direction of the vehicle, an accelerator for adjusting the moving speed in the moving direction, a brake, and the like. In response to the signal from the vehicle, the vehicle is controlled to travel on the traveling course, and it is attempted to record the completion time of the traveling course and the traveling distance within a predetermined time, or a vehicle object (enemy controlled by a computer). Car) and other players' own cars.

  In addition to the driving course, the virtual space includes data such as three-dimensional shapes and textures such as stationary objects such as guardrails, buildings, and forests, and moving objects that move under the control of computers such as enemy vehicles and ordinary vehicles. A plurality of objects are arranged, and an image (view image) of each object existing in a predetermined angle range in front of the own vehicle or in the axial direction of the own vehicle from a viewpoint fixed to the front side of the own vehicle or the own vehicle. It is synthesized and displayed on the monitor.

  Therefore, for example, when the host vehicle is moved straight, each object in the view image flows from the front to the rear, and when the traveling direction of the host vehicle is changed, the direction of the change is opposite. The moving state of the object will be displayed, and it will be possible to give the player who operates the vehicle while watching the monitor a virtual reality as if it were traveling with the vehicle in a three-dimensional space. It is.

  Also, when the actual vehicle travels in real space, not only the acceleration force and deceleration force in the direction of travel, but also when, for example, traveling on a curve or on a projection on the road surface Various external forces acting in a direction different from the traveling direction on the road surface, such as an upward force that works or an inertial force that acts in the direction that the vehicle body lifts off the road surface when the slope of the road surface suddenly changes from upward to downward However, these external forces cause the vehicle body to perform complex movements. However, in recent driving games, in order to reproduce such complex movements in an actual vehicle, the traveling direction of the traveling course is different from the traveling direction. A virtual external force in the direction is applied to the own vehicle, and the movement of the own vehicle due to the external force is also reflected in the above-described view image.

  In other words, if the vehicle bends the curve at a certain speed or more, it causes a side slip due to centrifugal force, which is expressed by the lateral movement of each object in the field of view image, and is placed on the running surface. When a single wheel is run on a raised projection (such as a curbstone), a single wheel running state is generated, and this is expressed by rotating the view image around the center point of the view image. When the vehicle passes through the top at a certain speed, the vehicle body jumps from the running surface, and each object in the view image is moved from the lower side to the upper side until the vehicle body reaches the running surface again. Processing such as expression is performed, and thereby, a device for making the virtual reality given to the player more realistic is devised.

However, in conventional drive games, image processing that assumes a virtual external force in a direction different from the traveling direction on the running surface is an effect that only gives a notice of a penalty such as a crash or a crash. However, there was no motivation for the player to actively slide his / her own vehicle, put it in a one-wheel drive state, or make a jump. There has been a problem in that the frequency of execution of processing for enhancing the reality of reality is not increased, and the attractiveness of the game device is not fully exhibited.
JP 2003-325968 A

  In view of the above problems, the present invention provides players with the motivation to perform operations such as drifting, jumping, one-wheel driving, spinning, etc. during the game, thereby realizing realistic virtual reality. It is an object of the present invention to provide a game apparatus capable of increasing the frequency of performing image display for giving a player a game, and a program thereof.

  The present invention solves the above-described problem, and a moving body travels on a traveling course set in a virtual space according to a player's operation, and a view image from a viewpoint fixed to the moving body is obtained. A game device displayed on a monitor, wherein a means for deriving a virtual external force acting in a direction different from a moving direction of the moving body on a running surface of the running course, and a movement of the moving body by the external force Means for changing the view image according to the number of times, means for calculating the technical point according to the number of times the view image has changed, or time, and means for displaying the technical point on the monitor. Or a viewpoint fixed to the moving body on the traveling course set in the virtual space according to the operation of the player. And a control for deriving a virtual external force acting in a direction different from the moving direction of the moving body on the traveling surface of the traveling course, and the moving body by the external force Control for changing the view image according to the movement of the image, control for calculating the technical point according to the number of times or the time when the change in the view image is generated, and control for displaying the technical point on the monitor Is a program characterized by causing the control means to execute.

  That is, in the present invention, when a change in the field of view image is generated according to the movement of the moving body due to a virtual external force in a predetermined direction, the technical point is derived according to the number and time of the change. Since this is configured to be displayed on the monitor, in order to obtain a higher technical point, the player must drive the moving body to generate a change in the view image as described above during driving. As a result, image processing for generating realistic virtual reality is executed more frequently.

  Here, the virtual external force acting in the direction different from the moving direction of the moving body on the traveling surface of the moving body in the present invention is when the moving body set with a virtually constant mass is traveling on the curve. The centrifugal force generated outward of the curve, the upward force generated when the moving body travels on the protrusion arranged on the traveling surface, and the inclination of the traveling surface on which the moving body is traveling For example, an inertial force acting in a direction away from the traveling surface acting on the moving body when suddenly turning downward.

  When a virtual centrifugal force is applied to the moving body, the road surface or the grip force of the tire is set according to the strength of the centrifugal force and the speed of the moving body at that time or in addition to these. Accordingly, the moving body moves such as drift and spin, and accordingly, control for changing the view image is performed, such as laterally shifting and rotating each object displayed in the view image. Note that not only when a moving object is traveling on a curve such as a curve, but also when a specific operation such as operating a brake and a shift lever with the steering wheel turned off is performed. It is also possible to cause drift or spin as a virtual external force generated in the direction.

  In addition, when a moving object rides on an object on a running surface with a certain height such as a curb and runs at a certain speed, the moving object tilts and moves one wheel. Along with this, a control for changing the view image is performed, such as rotating each object in the view image around the center point of the view image. In addition, operations such as rotating the steering wheel in a predetermined direction at the timing when the moving body tries to return from the one-wheel running state or when the mobile body is about to tilt and roll over from the one-wheel running state. If this is properly performed, it is possible to increase the time for one-wheel travel.

  In addition, when the moving body passes the top of the slope at a certain speed or more, the moving body jumps, and accordingly, the object in the view image is viewed from below until the vehicle body lands. Control to change the view field image is performed, for example, it is moved upward. In addition, as the angle of the slope increases and the traveling speed of the moving body increases, the time during which the moving body jumps can be lengthened, and the amount of movement of the object in the view field image from below to above can be increased. .

  Further, the present invention is based on the time required for the completion of the traveling course, or the means for calculating the traveling point according to the traveling distance within a predetermined time, and the total point which is the total value of the technical point and the traveling point. It may further comprise means for determining a rank or winning or losing.

  In this case, in order for the player to obtain higher rankings and victory, it is necessary not only to move the moving body at high speed but also to acquire more technical points. Players will be given more motivation to perform operations to generate image changes.

  In addition, the present invention further includes multiplayer setting means for accepting participation in a race from a plurality of players and setting a race group, and when a race group in which two or more players participate is set, The present invention can be applied to a game apparatus in which the traveling of a moving body operated by another player is started after the traveling of the moving body operated by another player is completed.

  In other words, a game device having such a multiplayer setting means enables a player to compete among a plurality of players using a single game device, but determines the ranking only by the running points. If this is the case, the subsequent players will know the results of the previous player in advance, which may reduce their interest in the middle of the play. The ranking of the game is added, or the technical points and the total points are displayed after all the players have finished running, so that the interest in the game is sustained until everyone's play ends. You can make it.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective explanatory view of a drive game apparatus 1 according to an embodiment of the present invention.

  As shown in the figure, the drive game apparatus 1 includes a seat 10 on which a player sits, a monitor 11 for displaying a game image, a speaker 12 for outputting game sound, and a moving body (self-operated by the player). A steering wheel 13 for adjusting the traveling direction of the car), a shift lever 14 for upshifting and downshifting, a start button 15 for designating the start timing of the game, and a driver's seat of the own vehicle. A view switching button 16 for switching between a view image from the selected viewpoint and a view image fixed from the viewpoint fixed to the front side of the host vehicle, and an accelerator for accelerating and decelerating the host vehicle in the traveling direction. 17, a brake 18, and a coin insertion slot 19 for accepting a usage fee.

  FIG. 2 is an explanatory diagram showing a system configuration of the drive game apparatus 1.

  The drive game device 1 includes a control device (CPU) 21 that controls the entire game device, a recording device such as a ROM 22, a RAM 23, and a hard disk 24, an external storage medium drive 25 such as a CD-ROM and a DVD, From an operation unit 28 such as an image synthesis IC 26, a voice synthesis IC 27, a handle 13, an accelerator 17, a brake 18, etc. that synthesizes a game image and game sound based on data generated by the control device 21 and outputs them to the monitor 11 and the speaker 12. The I / O port 29 for receiving these signals is connected to each other by a bus line 30.

  The hard disk 24 includes a plurality of traveling courses, and terrain data 24a that defines the terrain shape and texture of the surroundings, a vehicle object such as an own vehicle or an enemy vehicle moving along the traveling course with the vehicle, Stored are object data 24b that defines the shape and texture of objects such as buildings and guardrails arranged around the driving course, a program 24c for executing the drive game of the present invention, and the like.

  The ROM 22 stores a boot program and data necessary for starting the control device 21, and the RAM 23 is used as a working memory for the control device 21. The external storage medium drive 25 is used when installing the data and programs 24a to 24c on the hard disk 24.

  The control device 21 is based on the data in the hard disk 24, the programs 24a to 24c, or the operation signal from the operation unit 28, the own vehicle control unit 31, the enemy vehicle control unit 32, the image data generation unit 33, the sound data generation. Functional blocks such as a unit 34, a point calculation unit 35, and a rank / win / loss determination unit 36 are realized.

  The own vehicle control unit 31 includes an external force calculation unit 31a, a speed calculation unit 31b, an attitude calculation unit 31c, and a position calculation unit 31d. The external force calculation unit 31a acts on the own vehicle that is a moving body operated by the player. The external force is calculated.

  Here, not only is the external force acting in the traveling direction of the host vehicle calculated based on the signals from the accelerator 17 and the brake 18, but also when the host vehicle is traveling on a curve, for example, Centrifugal force acting on the vehicle is calculated from the locality radius of the vehicle and the traveling speed of the vehicle, or when the vehicle travels on a projection arranged on the traveling surface, the projection The external force in the direction different from the traveling direction is also calculated, such as calculating the external force upward from the height of the vehicle and the traveling speed of the host vehicle.

  Further, the speed calculation unit 31b adds the speed change calculated from the external force acting in the traveling direction calculated by the external force calculation unit 31a to the traveling speed of the vehicle one frame before, for example. The running speed is calculated every moment by a method such as updating the vehicle speed.

  In addition, the posture calculation unit 31 c adjusts the traveling direction of the own vehicle based on the signal from the handle 13.

  Further, as shown in FIG. 3, the posture calculation unit 31c defines an orthogonal coordinate XYZ with the center of gravity G of the host vehicle C as the origin, the axle as the X axis, and the vertical direction as the Z axis, and the external force calculation unit 31a. The following processing is executed based on an external force acting in a direction different from the traveling direction calculated in step (1).

  That is, when the centrifugal force acting on the host vehicle exceeds a predetermined value, drift occurs, and the vehicle body is rotated at a predetermined angle around the Z axis at a speed corresponding to the magnitude of the centrifugal force. If a side slip occurs in the direction of the centrifugal force and the centrifugal force exceeds a larger predetermined value, a spin is generated and the vehicle body is moved in the direction of the centrifugal force at a speed corresponding to the magnitude of the centrifugal force. Rotate continuously around the axis for a predetermined time.

  Note that a virtual external force in the Y-axis direction is applied even when a predetermined operation is performed on the operation unit 28, such as operating the shift lever 14 while stepping on the brake 18 and simultaneously rotating the handle 13. As a result, processing for generating drift and spin is performed in the same manner as described above.

  In addition, when an external force exceeding a certain value is applied to only one wheel, the vehicle body is rotated around the X axis in accordance with the external force to enter a single-wheel running state, and when passing the top of the slope When an external force exceeding a certain level is applied to both wheels, a jump state is generated and the vehicle body is moved in the Z-axis direction at a speed corresponding to the external force.

  In addition, at a timing when the vehicle body starts to rotate in the direction of returning from the state of one-wheeled driving or in the direction of falling, the steering wheel 13 is turned in the direction of rotation, and a predetermined operation is performed, for example. It is possible to maintain the state of the vehicle for a long time, and as the slope of the slope increases and the traveling speed immediately before reaching the top of the slope increases, the moving speed in the Z-axis direction also increases. The jumping time is long, and the amount of movement of the vehicle body in the Z-axis direction is increased.

  In addition, the position calculation unit 31d updates the position of the host vehicle every moment on the traveling course based on the speed calculated by the speed calculation unit 31b and the traveling direction adjusted by the posture calculation unit 31c.

  In the enemy vehicle control unit 32, movement control of an enemy vehicle that travels on a traveling course with the host vehicle as a player's competitor is performed in the case of “single play” described later.

  The enemy vehicle control unit 32 includes the same functional blocks as the host vehicle control unit 31, such as an external force calculation unit 32a, a speed calculation unit 32b, a posture calculation unit 32c, and a position calculation unit 32d. And the same as the vehicle control unit 31 except that the external force calculation unit 32a calculates the external force and the attitude calculation unit 32c adjusts the traveling direction based on an operation signal set in advance in the program 24c. Execute the process.

  The image data generation unit 33 uses the terrain data 24a and the object data 24b, and is fixed to the position of the own vehicle (the driver's seat of the own vehicle or the front side of the own vehicle) determined by the position calculation unit 31d. Image data of various objects such as a traveling course, enemy vehicles, guardrails, and the like existing within a predetermined angle range centered on the forward direction of the axle determined by the posture calculation unit 31c as viewed from the viewpoint position) is generated. At this time, if the vehicle body rotates around the axle, the image is rotated in the opposite direction of the rotation.

  The image data generated in this way is transmitted to the image composition IC 26, converted into a three-dimensional view image by a known method such as geometry processing or rendering processing, and displayed on the monitor 11.

  The voice data generation unit 34 generates a running sound corresponding to the running mode of the host vehicle or the enemy vehicle, or voice data such as back music, transmits the voice data to the voice synthesis IC 27, and outputs the voice data from the speaker 12.

  The calculation in the point calculation unit 35 is executed based on the point correspondence table shown in FIG.

  In the figure, the traveling point SP is a point given according to the time required to complete the traveling course. When the traveling point SP completes within 1800 frame time (1 minute), a point of 5000 pt is given. Each time the time required to complete the course increases by 30 frame times, the point obtained by subtracting 100 pt is the running point.

  The drift point DP is a point given for drifting the vehicle body. When the drift continues for 30 frame times, a point of 50 pt is given, and thereafter the drift time is increased by 1 frame. The point obtained by adding 2 pt to is the drift point.

  The jump point JP is given for jumping the vehicle body. If the jump continues for 30 frame times, a point of 50 pt is given, and then the jump time increases by 1 frame. The point obtained by adding 5 pt to is the jump point.

  The one-wheel travel point KP is a point given for traveling in the state of one-wheel travel, and when the state of one-wheel travel lasts for 30 frames, a point of 50 pt is given, and then A point obtained by adding 2 pt each time the one-wheel traveling time is increased by one frame becomes a one-wheel traveling point.

  The spin turn point TP is a point given when the traveling direction is reversed using spin, and a point of 300 pt is given for each successful spin turn.

  The point calculation unit 35 updates and records each of the above points during game execution, and totals the drift point DP, jump point JP, single wheel travel point KP, and spin turn point TP as technical points at the end of the game, In addition, the total of technical points and driving points is counted as a total point.

  In the case of “single play” described later, the rank / win / loss determination unit 36 determines the player's victory when the vehicle completes the running course before the enemy vehicle, and the “alternate play” described later. In this case, the rank is determined in descending order of the total points given for the traveling of the own vehicle operated by each player.

  Next, processing executed in the drive game apparatus of the present invention will be described with reference to FIGS.

  FIG. 5 is a flowchart showing the flow of the main control process.

  In the initial state, the drive game apparatus 1 displays a demonstration video such as a game title and a past player's score ranking display on the monitor 11 (step S1).

  When a predetermined amount is inserted from the coin insertion slot 19 and a credit is generated, a game mode selection screen is displayed on the monitor 11 and accepts selection of a game mode from the player (step S2).

  FIG. 6 shows an example of the game mode selection screen 41. Here, a battle is performed in a stage system between the host vehicle operated by the player and the enemy vehicle controlled by the computer. Each time you win, you can go to the next stage and play against new enemy vehicles, and “single play”, where multiple players can play a drive game and compete for driving points and technical points. "Competitive play" is displayed as options 42 and 43, and in the initial state, the option 42 of "single play" is highlighted to indicate that it is in a selected state, and the player can, for example, handle 13 or shift lever 14 The selection option can be changed by operating and the selection can be determined by depressing the accelerator 17. Note that a remaining time 44 for selection is displayed on the upper left of the screen, and when the remaining time becomes zero, the selection of the game mode in the selected state is determined at that time.

  When “single play” is selected in step S2, course selection reception (step S3) for receiving selection of a running course used in the race game process from a plurality of running courses recorded in the terrain data 24a, and an object The process of vehicle type selection reception (step S4) for receiving the selection of the own vehicle used in the race game process from the models of the own vehicle having different shapes and colors recorded in the data 24b is executed. The acceptance of the selection here is executed by a method substantially similar to the selection in step S2.

  After the selection in step S4 is confirmed, the race game process (step S5) is executed after the player operates the start button 15.

  The race game process (step S5) is executed until the vehicle completes the travel course or until a predetermined time limit elapses. After the race game process is completed, the point calculation unit 35 performs the travel points, technical points, and The total points are totaled and each point is displayed on the monitor 11 as a race result (step 6).

  The running points and technical points are the drift time DT, jump time JT, one-wheel running time KT, spin turn number TN, race game process, and the like recorded in the RAM 32 in the point calculation process (step S28) described later. It is calculated based on the frame count value T at the end and the point correspondence table in FIG.

  After the end of the race game process, the ranking / win / loss determining unit 36 determines whether or not the own vehicle has won (step S7). When the player wins, a battle with a different enemy vehicle is performed. In order to execute the race game process in the subsequent stage, the process is returned to step S4. If the player loses or the player wins, the game is played if all the prescribed stages are consumed. The process ends, and the process returns to step S1.

  In this way, in the “single play” game mode, technical points or total points to which technical points are added are displayed on the monitor 11 in the result display step (step S6), so that higher points are displayed. The player who wants to perform the action actively performs operations such as drifting, jumping, single wheel driving, spin turn, etc., and as a result, realistic images based on these movements. The effect of increasing the frequency with which the display is performed on the monitor 11 is achieved.

  If “alternative battle play” is selected in step S2, registration of other players participating in the race is accepted (step S8). Registration is done by putting the amount necessary for participating in the race into the coin insertion slot 19 within the predetermined time limit, and the registration will be closed when the time limit has passed or when the capacity is reached, A race group is composed of a plurality of players who have completed registration at that time. Even if “alternate play” is selected in step S2, if there is no registration from another player within the time limit, the game mode is switched to “single play”, and the process proceeds to step S3. To do.

  When registration from at least one other player is performed in step S8, the start of the course is selected after the selection of the driving course by the first player (step S9) and the selection of the vehicle type (step S10) are accepted. The race game process (step S11) is executed after the button 15 is operated. The selection acceptance in steps S9 and S10 is executed in a manner substantially similar to steps S3 and S4.

  The race game process (step S11) is executed until the vehicle completes the travel course or until a predetermined time limit elapses. After the race game process is completed, the point calculation unit 35 performs the travel points, technical points, and The total points are totaled and each point is displayed on the monitor 11 as a race result (step S12).

  Also in this case, the running points and technical points are the drift time DT, jump time JT, one-wheel running time KT, spin turn number TN, race, and the like recorded in the RAM 32 in the point calculation process (step S28) described later. It is calculated based on the frame count value T at the end of the game process and the point correspondence table in FIG.

  Subsequently, it is determined whether or not all the players in the race group have finished the race (step S13). If the races by all the players have been completed, the ranking / win / loss determining unit 36 determines each race group. The player's total points are totaled, and the player's ranking is determined based on the total points. Then, the ranking display (step S14) in which the ranking of each player, the total points, the running points, and the technical points are displayed on the monitor 11 is executed, and the game ends.

  On the other hand, if the race by all players in the race group has not ended, the process returns to step S10 in order to execute the race by the subsequent player.

  As described above, in the game mode of “alternative battle play”, in order to raise the ranking of the own vehicle, it is necessary not only to complete the driving course at high speed but also to acquire higher technical points. Therefore, the player is given a stronger motivation to perform operations such as drifting, jumping, single-wheel driving, spin turn, etc., and as a result, realistic images based on these movements The effect of increasing the frequency with which the display is performed on the monitor 11 is achieved.

  FIG. 7 is a flowchart showing the flow of an interrupt process repeatedly executed by the control device 21 every frame time (1/30 second) in the race game process of steps S5 and S11.

  In the interrupt process, first, a process of incrementing and updating the frame count T by 1 (step S21) is performed, and then various operation inputs are read from the operation unit 28 (step S22).

  Subsequently, the external force calculation unit 31a calculates the external force acting on the host vehicle (step S23). Based on the calculation result, the speed calculation unit 31b calculates the speed (step S24), and the posture calculation unit 31c calculates the posture. (Step S25) is executed, and further, the current position of the host vehicle is calculated by the position calculation unit 31d (Step S26).

  In the case of “single play”, at the same time, the enemy vehicle control unit 32 calculates the external force for the enemy vehicle in the same manner as the host vehicle control unit 31 according to the control signal incorporated in the program 24c (step S23). ), Speed calculation (step S24), posture calculation (step S25), and current position calculation (step S26).

  Subsequently, the image data generation unit 33 determines a region in the virtual space for generating an image as a view field image from the current position and posture of the own vehicle, and the terrain data 24a and the object data 24b in the region. The image data is generated based on (Step S27), and the image data is transmitted to the image composition IC 26.

  Thereafter, the point calculation process (step S28) shown in FIG. 8 is executed.

  In this point calculation process, first, in step S25, the posture calculation unit 31c determines whether the vehicle is drifting, jumping, traveling on one wheel, or spin-turning based on an external force acting in a direction different from the traveling direction. It is determined whether or not the processing to be generated has been performed (steps D1, J1, K1, and step T1).

  If the drift, jump, and single wheel travel processing has been performed, it is further determined whether the drift flag DF, jump flag JF, and single wheel travel flag KF are “0” or “1” (step D2). , J2, K2), “0”, that is, when these processes are started from the current frame time, “1” is given as the drift time DT, jump time JT, and one-wheel running time KT ( Steps D3, J3, K3), and when each of the flags DF, JF, KF is “1”, that is, when these processes are continued one frame time before, the drift time DT, jump time JT, The one-wheel travel time KT is updated by incrementing by “1” (steps D4, J4, K4). Thereafter, the drift flag DF, the jump flag JF, and the one-wheel travel flag KF are “ It is set to "(step D5, J5, K5).

  On the other hand, if the drift, jump, and single wheel travel processes are not performed in step S25, it is determined whether the drift flag DF, jump flag JF, and single wheel travel flag KF are “0” or “1” (step D6). , J6, K6) and "0", the flags DF, JF, KF are reset (steps D9, J9, K9).

  Further, when each of the flags DF, JF, and KF is “1”, it means that the processing of drift, jump, and single wheel running that has been executed up to the immediately preceding frame time has ended. DT, JT, and KT updated in the above are recorded in a recording device such as the RAM 23 (steps D7, J7, and K7), and then DT, JT, and KT are reset (steps D8, J8, and K8), and each flag DF , JF and KF are reset (steps D9, J9 and K9).

  If the spin turn process has been executed, the spin turn count TN recorded with the initial value “0” in the recording device such as the RAM 23 is incremented by 1 and updated (step T2), and then the point is changed. When the calculation process is terminated and the spin turn process is not executed, the point calculation process is terminated as it is, and the process returns to the interrupt process of FIG.

  When the point calculation process (step S28) ends, the interrupt process ends, and the control device 21 waits for the arrival of the next frame time.

  The present invention has been described above by taking the drive game device according to one embodiment of the present invention as an example, but the present invention is not limited to the above embodiment, and in the scope described in the claims, Various modifications are possible.

  For example, the present invention can be similarly applied to a game in which a moving body operated by a player is an object other than an automobile such as a motorcycle, a train, or a skier.

  In the above-described embodiment, a so-called arcade game machine in which a control device, an operation unit, a monitor, and the like are incorporated in a single casing has been described as an example. However, the program of the present invention is a CD-ROM, DVD- It is also possible to configure the game device of the present invention by recording it in a recording medium such as a ROM, and reading it from a home game machine or personal computer and executing it.

  In the above embodiment, the game device that selects the game mode from “single play” and “alternative battle play” has been described. However, only one of these can be played, Further, in place of these game modes or selectively with these game modes, a plurality of game devices of the present invention are operated by a plurality of players by mutually connecting them via a plurality of communication lines or the like. It is also possible to make it possible to perform “communication battle play” in which one's own vehicle can participate in the race at the same time.

  Further, in the above embodiment, the case where winning or losing is determined based on whether or not the own vehicle completes earlier than the enemy vehicle in “single play” has been described, but similar to the derivation of the driving points and technical points for the own vehicle The driving point, technical point, etc. of the enemy vehicle may be derived by the above method, and the victory of the own vehicle may be determined when there are more total points, driving points, technical points, etc. of the own vehicle than the enemy vehicle. Or, regardless of the victory or defeat of the enemy vehicle, if the technical points or total points exceed the predetermined value, the time limit of the race game processing can be extended to make it a game that can be played for a longer time Is possible.

  In addition, in “alternative battle play”, the case where the ranking is determined by the total points has been described, but other game modes such as “communication battle play”, including other game modes, such as completion order, technical point order, etc. It is also possible to determine the ranking and win / loss according to the method, and in order to further enhance the player's motivation for the acquisition of technical points, the player who is ranked first will continue to be "single play" It is also possible to give rewards such as being able to race.

  In “Alternate Battle Play”, the case where the vehicle operated by each player travels alone on the traveling course has been described. However, as in “Single Play”, each player's own vehicle races against enemy vehicles. Alternatively, in the race game process of the second and subsequent players, the traveling of the host vehicle operated by the preceding player with the shortest completion time may be displayed on the monitor as a so-called ghost car. .

  In the above embodiment, the technical points are described on the monitor after the race game process is finished. However, the technical points generated during the race game process can be displayed on the monitor sequentially. For example, when drift time DT, jump time JT, and one-wheel running time KT are recorded in steps D7, J7, and K7, and DT, JT, and KT are 50 or more, or spin turn in step T2. When the number of times is updated, the points defined in the point correspondence table in FIG. 4 can be displayed on the monitor sequentially.

  Further, in the above embodiment, the case has been described in which only the driving points, technical points, and total points are calculated, and only these points are displayed on the monitor in the result display and rank display steps. If the speed of the vehicle is continued for a predetermined time or more, when starting operation or when restarting the run after a crash, a sudden start operation can be performed within a preset time range, or a speed exceeding a predetermined value Generate additional points based on the player's operation, such as when approaching an enemy vehicle up to a predetermined distance with a difference, and such additional points or technical points and / or driving As with each of the above points, the result displayed is displayed on the monitor, or the points added to the points are displayed. By adding even additional points Do bovine determines the outcome and ranking may be as performing the display results based on the determination.
