Description of the Related Art Conventionally, a plurality of display objects are arranged in an object space which is a virtual three-dimensional space, and an image for generating an image in which the object space is viewed from a given virtual camera. Generating devices are known and are very popular for experiencing so-called virtual reality. Such an image generating apparatus is widely used for a simulator for performing a game and other simulations, and for other uses.

[0003] Taking a simulator capable of enjoying a motorcycle game as an example, a player can enjoy a three-dimensional game by driving a player's motorcycle on a course in an object space.

In a conventional motorcycle game or the like, when a player-operated motorcycle comes into contact with another motorcycle, a wall, or the like while traveling, the player's motorcycle is overturned when the relative speed at that time exceeds a reference speed. I was

[0005] However, when a player unfamiliar with the game operates the motorcycle, such a fall frequently occurs. As a result, the game does not progress easily, and the player cannot enjoy the fun of the game. There was a problem that the game would end without receiving it.

If the reference speed is increased to make it difficult for the player's motorcycle to fall over, a problem arises in that the game becomes unsatisfactory for advanced users.

[0007] For this reason, in the conventional simulator for games, it is difficult for beginners to advanced players to fully enjoy the game effects, and a strong motivation is given to a player who has finished the game to challenge the game again. There was a problem that it was difficult.

The present invention has been made in view of such conventional problems, and has as its object to provide a simulator, an image generation device, and an information storage medium that can be enjoyed by a wide range of simulations from beginners to advanced users. To provide.

[0009]

According to a first aspect of the present invention, there is provided a simulator for controlling a player moving body in a simulation space while watching a simulation screen. When a collision with an obstacle satisfies a predetermined collision determination criterion, collision directing means for performing an effect of generating a collision event of the player moving object, and a criterion changing means for changing the collision determination criterion according to a predetermined parameter. , Is included.

According to an eighth aspect of the present invention, there is provided an image generating apparatus for generating a screen in which an object space in which a player moving body controlled by a player moves is viewed from a given virtual camera. When a collision with an obstacle satisfies a predetermined collision determination criterion, a collision rendering means for rendering an effect of occurrence of a collision event of the player moving object, and a determination criterion changing means for changing the collision determination criterion according to a predetermined parameter, It is characterized by including.

According to a ninth aspect of the present invention, there is provided an information storage medium storing information for generating a screen as viewed from a given virtual camera in an object space in which a player moving body operated by a player moves. Medium, information for making a collision determination between the player moving body and an obstacle,
When the collision determination result satisfies a predetermined collision determination criterion,
It is characterized by including information for performing an effect of the occurrence of a collision event of the player moving object, and information for changing the collision determination criterion according to a predetermined parameter.

According to the present invention, the player can experience a simulation of maneuvering a player moving body in the simulation space or the object space while watching the screen.

[0013] Such simulators include, for example, a game device for controlling a player's moving body and enjoying a game, in addition to a device for experiencing a normal simulation.

At this time, when a collision occurs in which the player's moving body controlled by the player comes into contact with or hits an obstacle, for example, another moving body or a fixed obstacle, the level of the collision is determined. A collision determination is made. When the collision determination result satisfies a predetermined collision determination criterion, an effect of the occurrence of a collision event of the player moving object is performed. Although the content of such a collision event can be arbitrarily set depending on the content of the simulation, for example, it can be produced as an event including at least one of a fall, a crash, and a spin of the moving object of the player.

In a conventional simulator, such a collision event is configured to be generated only when the collision determination result satisfies a predetermined collision determination criterion, so that it is difficult for some beginners to control the player's moving body, or However, for advanced users, there has been a problem that the reality of the operation of the player moving body is poor.

On the other hand, according to the present invention, a wide variety of players, from beginners to advanced players, can experience a realistic simulation by changing the collision determination criterion at any time according to predetermined parameters. In particular, by applying the simulator, the image generation device, and the information storage medium of the present invention to a game device, a strong motivation to challenge the game again can be given. At this time, it is preferable to use at least one of the number of times of occurrence of a collision event and the number of times of collision between the player moving body and the obstacle as the parameter.

As described above, according to the present invention, even when the player's moving body controlled by the player collides with an obstacle, a collision event is generated in accordance with the level of the player, and a wide range of simulations from beginners to advanced users can be performed. Simulator that allows you to enjoy the game,
An image generation device and an information storage medium can be provided.

According to a third aspect of the present invention, in any one of the first and second aspects, the collision criterion is set as a relative reference speed between a player moving object and an obstacle, and the criterion changing means includes: The relative reference speed is changed using the number of times of occurrence of the collision event as a parameter.

According to an eleventh aspect of the present invention, in any one of the ninth and tenth aspects, the collision criterion is set as a relative reference speed between a player moving body and an obstacle, and information for changing the criterion is used. Is characterized by including information for changing a relative reference speed using the number of times of occurrence of the collision event as a parameter.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the collision criterion is set as a relative reference speed between a player moving object and an obstacle, and the criterion changing means includes: The relative reference speed is changed by using the number of collisions between the player moving object and the obstacle as a parameter.

According to a twelfth aspect of the present invention, in any one of the ninth to eleventh aspects, the collision criterion is set as a relative reference speed between a player's moving body and an obstacle, and information for changing the criterion is used. Is characterized by including information for changing the relative reference speed, using the number of collisions between the player moving object and the obstacle as a parameter.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the criterion changing means uses at least one of the number of times of the collision event and the number of times of the collision as the parameter. The speed is gradually increased, and when at least one of the collision event occurrence number and the collision number exceeds a predetermined value, the relative reference speed is greatly increased.

According to a thirteenth aspect, in any one of the ninth to twelfth aspects, the information for changing the determination criterion is obtained by using at least one of the collision event occurrence number and the collision number as the parameter. Relative reference speed is gradually increased, and when at least one of the number of times of occurrence of the collision event and the number of times of collision exceeds a predetermined value, information for greatly increasing the relative reference speed is included.

According to a seventh aspect of the present invention, in any one of the first to sixth aspects, an input means for the player to perform level input, and an initial value of the collision determination reference and a reference change condition are stored for each level. Storage means, and the determination criterion changing means sets an initial value of the collision determination criterion based on the input level of the player, and sets the collision determination criterion under a reference change condition based on the input level. It is characterized by changing.

According to the present invention, the collision criterion is set as a relative reference speed between the player moving object and the obstacle. When the player moving object collides with the obstacle at a speed higher than the reference speed, a collision event is generated. Occur.

At this time, by changing the relative reference speed using the number of times of occurrence of the collision event as a parameter, the occurrence of the collision event can be performed at a frequency corresponding to the level of the player.

Further, according to the present invention, the technique of the player is determined by using not only the number of occurrences of collision events but also the number of mere collisions between the player's moving body and the obstacle as a parameter.
The relative reference speed may be changed.

[0028] In this manner, a collision event can be generated at a frequency corresponding to the control level of the player, so that a wide range of simulation experiences can be enjoyed by beginners to advanced users.

In particular, by controlling the relative reference speed to be increased whenever at least one of the number of times of occurrence of the collision event and the number of times of collision increases, the novice player's moving body gradually becomes less likely to generate a collision event. This makes it possible to enjoy the operation of the player's moving body without being disturbed by the collision event, and for advanced users to enjoy the simulation while feeling the tension of the occurrence of the collision event.

As described above, according to the present invention, since a collision event is generated at a frequency according to the level from a beginner to an advanced user, it is possible to enjoy a wide range of simulation experiences from a beginner to an advanced user. By applying the present invention to the game device, it becomes possible to give a strong motivation to the player who has finished the game to challenge the game again, and as a result, the operating rate of the game device itself can be increased. It becomes possible.

Further, in the present invention, when the number of times of occurrence of the collision event or the number of times of collision exceeds a predetermined value, the relative reference speed is greatly increased so that the probability of occurrence of the collision event is greatly reduced. It is preferable to configure.

Thus, immediately after the start of the simulation, if a collision event such as a fall or a spin occurs due to a collision with an obstacle, the player is automatically determined to be a beginner, A situation is set in which a collision event is unlikely to occur even when the player's moving body comes into contact with an obstacle. For this reason, the beginner can control the player's moving body while enjoying various effects in the simulation space without being obstructed by obstacles or the like. In addition, since an advanced person rarely causes a collision with an obstacle, it is possible to enjoy, for example, a time attack, a competition with another player, and the like while maintaining a sense of tension that a collision event occurs.

By doing so, it is possible to provide a simulator, an image generating device, and an information storage medium that allow a beginner to enjoy a simulation more easily and an advanced user to enjoy a simulation with a sense of tension. it can.

Further, according to the present invention, it is preferable to adopt a configuration in which when a player performs a level input, an initial value of a collision determination reference and a reference change condition corresponding to the input level are automatically used.

Thus, a collision event can be generated at a frequency corresponding to the player's operation level immediately after the start of the game.

[0036]

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings. Here,
The case where the present invention is applied to a motorcycle game will be described as an example, but the game to which the present invention is applied is not limited to this.

FIG. 1 is a functional block diagram of a simulator for a motorcycle game to which the present invention is applied.

Here, the operation unit 10 is used by a player to operate the accelerator and brake, or to input operation data by rolling a vehicle body (see FIG. 11) simulating a motorcycle. Operation data obtained by the operation unit 10 is input to the processing unit 100.

The processing section 100 performs a process of arranging a display object in an object space, which is a three-dimensional game space, based on the operation data and a given program, and a process of viewing the object space at a given virtual camera position. This is a process for generating an image. The function of the processing unit 100 is as follows.
It is realized by hardware such as a CPU (CISC type, RISC type), DSP, and image generation IC.

The information storage medium 160 stores programs and data. The function of the information storage medium 160 is a CD-ROM, a game cassette, an IC card,
It can be realized by hardware such as MO, FD, DVD, hard disk, and memory. The processing unit 100, based on the program and data in the information storage medium 160,
Various processes will be performed.

The processing section 100 includes a game calculation section 10 and an image generation section 150.

Here, the game calculation section 110 receives an entry to the game, progresses the game, determines the position and direction of the moving object, determines the viewpoint position and direction, and displays the object in the object space. Processing such as placement is performed.

FIG. 3 shows a viewpoint 2 set so as to follow the player bike 30 controlled by the player while having a predetermined inertia with respect to the player bike 30.
This shows a state where 2 (virtual camera) is set.

More specifically, the game operation unit 110
Moves a motorcycle operated by a player, another player, a computer, or the like on a course in an object space (simulation space) based on the operation data input from the operation unit 10 or a given program. Perform the operation. The calculation for obtaining the position and direction of the moving body is performed, for example, for each inter.

At this time, the calculation for obtaining the position and the direction of the viewpoint 22 based on the position and the direction data of the player moving body is also performed at the same time. More specifically, the viewpoint 22 is set so as to follow the player motorcycle 30 operated by the player with inertia as shown in FIG.

The image generation unit 150 includes a game operation unit 110
Viewpoint 22 in the object space set by
, A process of generating an image in which the object space is viewed. The game image generated by the image generation unit 150 is
It is displayed on the display unit 12.

Here, such a player bike 22
The vehicle contacts or hits an obstacle, for example, another motorcycle, a wall beside a course, a grove, or the like during traveling. For this reason, the collision between the player bike 30 and the obstacle is determined,
A collision event such as falling, spinning or crashing the player bike 30 is usually performed based on the determination result.

A feature of the present embodiment is that such a collision event of the player bike 30 is automatically set so as to occur at a frequency corresponding to the driving level of the player, so that a beginner to an advanced player can enjoy the game widely. That's what I did.

For this reason, the game operation section 110 is based on the programs and data stored in the information storage medium 160 and the collision effect section 112 and the criterion change section 114
It is configured to function as.

The configuration will be described below.

In this embodiment, the player bike 30
And the collision criterion for generating a collision event with an obstacle,
The speed is set as a relative speed between the player bike 30 and the obstacle. More specifically, when the player bike 30 collides with a stationary object such as a wall or a moving object such as another player motorcycle in a state where the speed exceeds a predetermined reference speed, a collision event that causes the player motorcycle 30 to fall down is performed. Make an occurrence.

Here, for the sake of simplicity, it is assumed that the relative reference speed for determination with respect to a stationary object such as a wall is VM and the relative reference speed for determination with respect to a moving object such as another player motorcycle is VN. Therefore, when the player bike 30 collides with a stationary object such as a wall at a speed equal to or higher than the reference value VM, a game effect in which the player bike 30 falls down is performed, and the relative speed with respect to other player bikes is increased. Even when the vehicle hits at a speed of VN or more, a game effect in which the player motorcycle 30 falls down is performed.

As described above, when the player bike 30 falls, the player bike 30 cannot be restarted for a few seconds thereafter, and a time loss occurs accordingly. As a result, it takes too long to reach the goal,
In addition, the game may not pass the checkpoint for extending the game time within the predetermined time, and the game may end immediately.

Therefore, the player is able to play the player bike 30
You need to be very careful not to fall into contact with obstacles and fall.

FIG. 4 shows the initial values of the reference values VM and VN,
A table of increase data ΔVM, ΔVN for updating is displayed, and if the player selects a beginner course, an intermediate course, or an advanced course before the game starts, the initial value and the increase corresponding to those are automatically set. It is configured.

Such table data is stored in the information storage medium 160 in advance.

The criterion changing unit 114 sets initial values of the relative reference speeds VM and VN based on the course selected by the player prior to the start of the game.

When the player 20 collides with an obstacle, the collision rendering unit 112 determines whether or not the relative speed at that time exceeds the relative reference speed. When the relative speed is VM when the obstacle is a stationary object, and when the relative speed exceeds VN when the obstacle is a moving object, an effect of generating a collision event that causes the player bike 30 to fall is performed. , VN, a game effect is produced in which the player bike 30 runs without falling down.

Each time the player bike 30 collides with an obstacle and falls down, the criterion changing unit 114 updates the relative reference speeds VM and VN according to the following formulas so that the player bike 30 gradually becomes difficult to fall down. Set. VM = VM + ΔVM (1) VN = VN + ΔVN (2) By doing so, for a beginner who is likely to repeatedly hit an obstacle, the player bike 30 is less likely to fall over, so the setting is made along the racing course. The game can be played to the end while enjoying the various game effects that have been performed.

The advanced player rarely touches an obstacle and rarely falls down, but often takes a very severe course when, for example, time attacking or competing with another player. In such a case, if the player bike 30 comes into contact with a fixed obstacle or another player bike, the player bike 30 easily falls over, resulting in a time loss. For this reason, the advanced player can feel the tension of proceeding the game while balancing such risk and time attack, and this is an extremely interesting game for the advanced player.

Next, the processing of this embodiment will be described with reference to FIG.
This will be described in detail with reference to the flowchart shown in FIG.

First, when a coin is inserted into the game device, a level selection screen for an advanced course, an intermediate course, and a beginner course is displayed on the game screen. The player uses the operation unit 10 to select a course of a desired level (step S10).

When the level is selected in this manner,
The criterion changing unit 114 sets the initial values of the relative reference velocities VM and VN serving as the criterion for collision determination from the table data shown in FIG. 4 stored in the information storage medium 160.
At this time, the reference speeds VM and VN are set to a small value for the player who has selected the advanced course. As a result, the player bike 30 is likely to fall when it comes into contact with an obstacle, and when the elementary course is selected. Has the reference value V
M and VN are set to large values, and the player bike 30 is relatively unlikely to fall.

When the game starts (step S14), the player operates the steering wheel, accelerator, brake and the like of the operation unit 10 to operate the player motorcycle 30. 5 to 8 show specific examples of the game screen displayed on the display unit 12 at this time. The player
By running faster than a motorcycle steered by a computer or a bike steered by another player, the ranking can be increased.

At this time, if the speed is excessively increased, an obstacle around the course, such as a wall, comes into contact.

Also, if another motorcycle is running ahead and tries to overtake it, the motorcycle often encounters this motorcycle.

For this reason, the collision effect section 112 performs a collision determination, that is, a hit check, for each frame, whether or not a collision has occurred with an obstacle, for example, a stationary object or another motorcycle (step S16).

If it is determined that a collision has occurred, the number of collisions N is counted (step S18).
Next, it is determined whether or not the relative speed between the obstacle and the player bike 30 exceeds the above-described reference speed. If the collision target is a stationary object, it is determined whether or not the relative speed has exceeded VM. If the collision target is on another motorcycle, it is determined whether or not the relative speed has exceeded the reference speed VN. Is performed (step S20).

When it is determined that the speed exceeds the reference speed, a game effect is performed in which the player bike 30 is turned over for a predetermined time, and after the predetermined time elapses, a game effect is performed in which the player bike is controlled to be restartable. (Step S22).

FIGS. 5 to 8 show a series of game screens displayed in this case.

First, as shown in FIG. 5, in a state where another motorcycle 32 is running ahead, in an attempt to overtake it, as shown in FIG. Contact, this contact is detected in step S16, and the number of collisions N is incremented by one.
In step S20, the relative speed of the motorcycle 30 with respect to the motorcycle 32 is equal to the determination reference speed V for the moving object.
It is determined whether or not the number exceeds N. If it is determined that the number exceeds N, in step S22, a game screen in which the player motorcycle 30 falls down is displayed as shown in FIG. After a lapse of a predetermined time, the player bike 30 that has fallen over is displayed as an image that can be restarted, as shown in FIG. 8, and the player restarts the motorcycle 30 from the fallover position.

If it is determined in step S20 that the relative speed of the contacted player motorcycle 23 does not exceed the reference speed, the collision event generation effect in step S22 is not performed, and the relative reference speed in step S24 is not performed. Is determined.

In step S24, first, step S
A first update determination is made based on whether or not the overturn process of 22 has been performed. In this first update determination, step S22
If it is determined that the falling process has been performed, the next step S
26, the relative reference velocities VM and VN are calculated by the above formula (1);
A first update process of changing based on equation (2) is performed.
As a result, the reference speeds VM and VN are increased, and the player bike 30 is set so as not to fall down.

At this time, if the player has selected the elementary course, the increments ΔVM and ΔVN at the time of updating are set to large values. Therefore, each time the player bike 30 falls, the player bike 30 becomes more difficult to fall. When the advanced course is selected, the increments ΔVM and △ VN are relatively small, so that step S
Even if the reference speeds VM and VN are updated at 26, the player bike 30 does not relatively easily fall down.

As described above, by making the fall of the player bike 30 easy to fall depending on the level of the course selected by the player, the frequency of the fall of the player bike 30 is reduced for the beginner, and the motorcycle game is enjoyed accordingly. Also, for advanced users, the game can be advanced while enjoying the inherent risk of falling of the player bike 30, and both beginners and advanced players can fully enjoy the fun of the game. .

In step S24, in addition to the above-described first update determination based on the occurrence of the falling event, a determination is made based on whether the number of times the player bike 30 has fallen exceeds a predetermined reference value, for example, four times. 2 is determined. If it is determined in the second update determination that the number of falls of the player motorcycle 30 has exceeded a predetermined reference value, for example, four, in the next step 26, a normal case (in the case of the first update process) ), A second update process for VM and VN is performed. That is, when the values of the increments ΔVM and ΔVN shown in the above equations (1) and (2) are set to values sufficiently larger than usual, for example, when the normal value is 3 km / H, 20
After the fall of the fourth time, the reference speeds VM and VN are increased at a stretch by 20 km / H, and the reference speed is changed so that the player bike 30 hardly falls.

Thus, even if a complete beginner plays the game, the player bike 30 can run on the course with almost no fall after the fourth fall. The game can be played while enjoying the set various game effects, and a strong motivation to challenge the game again after the game can be given.

Further, in step S24,
In addition to the first and second update decisions, the player bike 3
A third update determination based on whether the number of times 0 collides with another obstacle (in this case, the number of times the player bike 30 does not fall over) also exceeds a predetermined reference value, for example, 20 times. Done. As a result of the third update determination, when it is determined that the value has exceeded, the player of the player motorcycle 30 is determined to be a beginner, and in the next step 26, the relative reference speeds VM and VN are changed. 3
Is updated. In this case, the values of ΔVM and ΔVn may use the same values as in the first updating process, or may adopt the same values as in the second updating process.

In the present embodiment, such a step S
The processes of 16 to S26 are repeatedly performed for each frame until it is determined in step S28 that the game has ended.

By doing so, it is possible to control the player bike 30 so that it does not easily fall down every time the player bike collides and falls down. As a result, the player bike 30 can be controlled at a frequency matching the level of the player. Falls down, and it is possible to provide a game device that allows beginners to advanced players to enjoy the game.

In the above-described embodiment, the case where the player bike 30 is overturned is described as an example of the collision event. However, a crash event, a spin event, and other collision events corresponding to the game content may be generated as necessary. Of course, you can do that.

In the above embodiment, the collision criterion is determined based on the relative speed between the player bike 30 and the obstacle. However, the criterion is set in consideration of other factors, for example, the collision angle. Alternatively, the collision criterion may be set from a completely different viewpoint depending on the content of the game.

In any case, the same operation as that of the above-described embodiment is performed by adopting a structure in which the collision determination criterion is changed at any time so that a collision event of the player's moving body is less likely to occur every time a collision event occurs. The effect can be achieved.
