DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described by taking a commercial video game device for racing on a racing course set in a three-dimensional game space as an example.

The three-dimensional video game device of the embodiment is formed such that a player racing car operated by a player competes with an opponent racing car of another player or a computer car operated by a computer.

FIG. 2 shows a circuit race type game system of the embodiment. In the game system of the embodiment, a plurality of independent game devices 1-1, 1-2, ...
They are connected to each other via a data transmission line.

Here, independent game devices 1-1, 1-
2, means that each of the game devices 1-1, 1-2, ... Is formed so as to be able to independently play a single player game. Of course, it is also possible to play a multi-player game in the same game space with other players via the data transmission line.

Each game device is formed similarly to the driver's seat of an actual racing car. And the player
While sitting on the seat 18 and watching the pseudo three-dimensional image (game screen) displayed on the display 10, the operation unit 12
A game is performed by operating a fictitious racing car by operating a steering wheel 14, an accelerator 15, a shift lever 16, a brake and the like provided on the vehicle.

FIG. 1 shows a block diagram of the game device.

The commercial video game apparatus of the embodiment has an operation section 12, a game calculation section 100, and an image composition section 200.
And the display 10.

The operation unit 12 includes a handle 14 shown in FIG.
It is a member operated by the player, such as the shift lever 16 and other pedals.

The game calculation section 100 is the player operation section 1
Various game calculations are performed based on the input signal from 2 and a predetermined game program, and a game screen for a driving game is displayed on the display 10 by using the image combining unit 200. Here, the game calculation unit 100 is arranged in a predetermined three-dimensional game space,
On the racing course 20 set as shown in FIG. 4, game calculation is performed so that the racing car moves by the player's control. Then, the three-dimensional game space is perspective-projected into a projection plane of a predetermined viewpoint coordinate system by using the image synthesizing unit 200 to form a game screen, which is displayed on the display 10.

FIG. 3 shows a principle diagram of such an image synthesizing method.

In the game device of the embodiment, information about the three-dimensional game space 500 and the three-dimensional object 510 appearing in the three-dimensional game space 500 is stored in advance. The image information relating to the three-dimensional object 510 includes a plurality of polygons 512-1, 512-2,
It is expressed as a shape model consisting of 512-3, ...
Pre-stored in memory.

Taking the driving game as an example, the three-dimensional object 510 is a racing car that appears in the three-dimensional game space 500, and in the other three-dimensional game space 500, for example, as shown in FIG. Racing course 20, building 30, tunnel 32, mountain 34, cliff 3
6, various three-dimensional objects representing the background such as the wall 38 are arranged.

The racing course 20 has a plurality of corners 22 and is provided with ups and downs or banks depending on the location, and also has a three-dimensional intersection.

These three-dimensional objects are perspective-projected on the perspective projection plane 520 of the viewpoint coordinate system centering on the viewpoint 610 of the virtual player, and displayed on the display 10 as a pseudo three-dimensional image 522. That is, when the player 600 looks at the display 10 from the viewpoint 610 with the operation unit 12 in front, he / she can see an image as if he / she sits in the driver's seat of the racing car and is located in the three-dimensional space 500. .

When the player 600 operates a steering wheel or the like of the operation unit 12 to rotate or translate a racing car that he / she virtually rides, the position of the viewpoint 610 with respect to the three-dimensional space 500 changes. However, the three-dimensional space 500 is rotated and translated. Therefore, the game calculation unit 1
00 performs rotation, translation, etc. of the three-dimensional object 510, which is a racing car, and other three-dimensional objects that make up the three-dimensional game space 500 based on the operation signal and the game program in real time.
Then, as described above, these three-dimensional objects are perspective-projected on the perspective projection surface 520, and the display 10 is displayed as a pseudo three-dimensional image 522 that changes in real time.
Displayed above.

Therefore, the player 600 has the operation unit 1
By operating 2 and operating the racing car, 3
It is possible to virtually simulate the state of participating in the race while driving the racing car in the circuit course 20 set in the three-dimensional game space 500.

When a computer graphics method is used, the shape model of the three-dimensional object 510 is created using an independent body coordinate system. That is, each polygon that forms the three-dimensional object 510 is arranged on this body coordinate system, and its shape model is specified.

Further, the three-dimensional game space 500 is constructed by using the world coordinate system (XW, YW, ZW), and the three-dimensional object 510 represented by using the body coordinate system.
Are placed in the world coordinate system according to their kinetic model.

Then, with the position of the viewpoint 610 as the origin,
The data is converted into a viewpoint coordinate system in which the direction of the line of sight is the positive direction of the Z axis, and the respective coordinates are perspective-projected into the screen coordinate system which is the projection surface 520. In this way, the image within the field of view of the three-dimensional game space 500 that can be seen from the viewpoint 610 can be displayed on the display 10.

In particular, the game calculation section 100 of the embodiment is formed so that the position of the viewpoint 610 can be arbitrarily changed in the three-dimensional game space 500 constituted by the world coordinate system. For example, in FIG.
By setting it behind the three-dimensional object 510 as shown in -A, it is possible to display an image of the three-dimensional game space 500 viewed from the rear of the racing car as shown in FIG. Further, in FIG. 3, the viewpoint position is 610-
By setting the three-dimensional object 510 in the sky as shown in B, it is possible to display a game screen that gives a bird's eye view of a running racing car. In the embodiment, the viewpoint position is set to the rear 610-A of the racing car during the game.

In the commercial video game apparatus of the embodiment, when the game is started, the racing car driven by the player starts from the start point 40. At the same time, the time calculation unit 114 of the game calculation unit 100 calculates the elapsed time from the start of the player car using the unit time of (1/60) seconds when the game screen is updated and displays it on the display. indicate. An example of this is shown in FIG. 5A, in which the player car 700 is displayed in the center of the game screen, and the elapsed time 710 since the player car has started is displayed in the upper right corner as moving time. Since the calculation of the elapsed time 710 is performed every time the game screen is updated, the value is incremented by 16 msec (1/60 seconds). For example, immediately after the start, 0 msec, 16 msec, 32 mse each time the game screen is updated.
c, 48 msec, ... are sequentially updated and displayed.

In the game device of the embodiment, after the player car has started, the game course 20 is rotated once, and if the checkpoint 42 is passed within a predetermined time limit, the time is extended, and the game course is rotated once again. Is formed so that it can be. Then, after going around the game course a predetermined number of times and passing the checkpoint 42,
It becomes a goal and the player's ranking is decided. At the same time, the elapsed time 710 displayed on the display is stopped, and the goal-in time is calculated and displayed.

By the way, as described above, the elapsed time 710 of the player car is updated as an integral multiple of the unit time 1/60 seconds (16 msec) in which the game screen is updated. Therefore, the display becomes comparatively rough, and in the conventional device that simply displays the goal-in time by using the unit time, the player car and other racing cars play dead heat with each other within 1/60 seconds. Even if they scored before and after, the goal-in times could be the same even though the rankings were different.

In the embodiment, such a situation is prevented, the goal-in time which accurately reflects the time of the goal-in turn of each racing car is calculated, displayed on the display, or output by voice. ing.

Therefore, the game calculation unit 100 of the embodiment.
Is configured to include the position calculation unit 110, the point passage detection unit 112, and the time calculation unit 114 described above.

The position calculation unit 110 is formed to calculate the position of the player car at the time of updating the game screen based on the updated data every time the game screen is updated.

The point passage detector 112 detects whether or not the player car has passed the goal line 42 set as a check point in advance, based on the position data of the player car.

For example, as shown in FIG. 6, when a predetermined game screen is updated, the position of the player car calculated by the position calculation unit 110 is set to 800, the position of the goal line is set to 42, and the direction of the arrow in the drawing indicates the position of the racing car. Assume the direction of travel. In this case, the point passage detection unit 112 determines that the player car has passed the goal line 42 based on the position data 800 input from the position calculation unit 110. That is, the point passage detection unit 112 detects whether or not the player car has passed the goal line 42 based on the position data 800 of the player car calculated by the position calculation unit 110. When the passage of the goal line is detected, the distance from the goal line 42 of the player car to the current position 800 is calculated as the overrun distance l.

When the point passage detection unit 112 determines that the elapsed time from the start at the time of updating the game screen determined to have passed the goal line is n / 60 seconds, the time calculation unit 114
Is the elapsed time n / 60 seconds and the overrun distance l
The goal line passing time of the player car, that is, the goal-in time T is calculated based on

In the embodiment, this calculation is specifically performed as follows.

First, as shown in FIG. 6, the reference moving distance of the player car per unit time (1/60 seconds) when the game screen is updated is set to L. In the embodiment, this L
Is set to a distance that the player car can move in 1/60 second at the speed at that time. However,
As the reference movement distance L, a predetermined value may be used.

Then, a calculated goal line 810 is set at a position ahead of the actual goal line 42 by the reference movement distance L.

Then, the measurement point 80 of the player car
Assuming that the moving time of the player car from 0 to the calculated goal line 810 is t, a virtual goal in time T1 at which the player car passes through the calculated goal line 810.
Is given by T1 = (n / 60) + t.

Since the distance that the player car can move at the speed at that time in 1/60 seconds is L, the following approximate expression holds between the distance and the time. L: (1/60) = (L-1): t When t is obtained from this equation, the following equation is obtained. t = (L-1) / 60L Therefore, by substituting this t into the equation of T1, the virtual time T1 for the player car to pass the calculated goal line 810 is given by the following equation. T1 = 1/60 (n + (L-1) / L) The time calculation unit 114 of the embodiment actually calculates the virtual goal in time T1 when the player car passes the calculated goal line 810 set in this way. Goal line 4
2 is calculated as the goal-in time T which the player car passes, and is displayed on the display 110 as the goal-in time 720 as shown in FIG.

As described above, according to this embodiment, the goal-in time can be calculated and displayed with higher accuracy than the unit time (1/60 seconds) for updating the game screen. As a result, even when a plurality of players make a goal in front of each other, the goal-in order is accurately reflected, and 1 / 100th is achieved.
The goal-in time can be displayed with the same feeling as in an actual race in 0 second units, and the atmosphere immediately after the goal-in of a racing car can be excited.

In the above embodiment, the calculated goal line 810 is set farther from the actual goal line 42, but in the actual video game, such slight positional deviation causes almost no problem. That is, the positional deviation in the three-dimensional game space by about the reference movement distance L causes almost no problem for the player's sense.

On the contrary to the above embodiment, the actual goal-in time on the goal line 42 may be calculated approximately.

That is, when the virtual goal in time of the player car at the time of passing the goal line 42 shown in FIG. 6 is T2, this goal in time T2 is (1) from the elapsed time n / 60 seconds from the start at the measurement point 800. / 60-t) seconds.

That is, it is given by the following equation. T2 = n / 60- (1 / 60-t) = (n-1) / 60
+ T = (n-1) / 60 + (L-1) / 60L = 1/60 (n-1 + (L-1) / L) In this way, the virtual goal in time T2 in the actual goal line 42 is calculated. This may be displayed on the display. Even in this case, it is possible to display a highly accurate goal-in time on the display, which accurately reflects the actual ranking of each player car.

Further, FIG. 7 shows another principle of calculation of the goal-in time T. In this specific example, the point passage detection unit 112 has an overrun distance l1 from the goal line 42 to the moving position of the player car at the time of updating the game screen immediately before and immediately after the player car passes the actual goal line 42. , 12 is formed.

Then, the time calculation unit 114 uses the following formula based on the moving time n / 60 seconds of the player car at the time of updating the game screen immediately after the goal-in and the distances l1 and l2, and uses the following equation to calculate the time when the goal line 42 passes. It is formed to calculate the virtual goal-in time T of the player car at.

T = (n-l2 / (l1 + l2)) / 60 By doing so, the goal-in time T can be more accurately calculated by the correction operation as compared with the specific example shown in FIG.

In the specific example shown in FIG. 6, it is not necessary to store the position data of the player car in the memory or the like until the goal-in of the player car is detected.
In the specific example shown in (1), the distance l1 to one goal in is calculated based on the position data immediately before the goal in. Therefore, when the calculation method shown in FIG. 7 is adopted, not only the position data of the player car at the time of updating the current game screen but also the position data at the time of updating the previous game screen are stored in the memory. Since it is necessary to store the data, the goal-in time T can be calculated accurately, but the work of writing and saving the data in the memory increases.

FIG. 8 shows an operation flowchart of the game system of the embodiment.

First, in the game device of the embodiment, when the game is started, the racing car driven by the player starts from the start point 40. At the same time as FIG.
The operation for measuring the elapsed time indicated by is started.

Then, the position calculation section 110 and the time calculation section 114 calculate the position of the player car and the elapsed time n / 60 seconds at that time every time the game screen is updated every 1/60 seconds (step S60). S10). Here, n represents the number of game screen updates since the start.

Then, based on the position data, it is judged whether or not the player car has finished the goal (step S
12) If it is determined that the goal is not reached, (n /
The elapsed time of 60) seconds is displayed on the display 10 together with the game screen (step S14).

Then, when the player car orbits the game course a predetermined number of times and makes a goal (step S1).
2) Using the method shown in FIG. 6 or the method shown in FIG. 7, the goal-in time T is calculated and displayed on the display (steps S16 and S18).

Goal-in time T obtained at this time
Is calculated based on the elapsed time n / 60 seconds measured at the time of screen update immediately after passing the goal line and the overrun distance 1 from the goal line of the racing car at that time. The goal-in time T thus obtained is obtained at a time interval smaller than the unit cycle 1/60 seconds of the game screen. In particular, in the system of the embodiment, even when a plurality of racing cars make a goal in front of each other within 1/60 seconds, the goal-in time that accurately reflects the order of goal-in is corrected / calculated in 1/1000 second units and displayed. Since it can be displayed above, the atmosphere of the game immediately after the goal can be raised with the same feeling as in an actual race.

The present invention is not limited to the above-mentioned embodiments, but various modified embodiments are possible within the scope of the gist of the present invention.

For example, in the above embodiment, the case of playing a game in a three-dimensional game space has been described as an example, but the present invention is not limited to this, and the same applies to other games, for example, a two-dimensional game space. Needless to say, it can be applied even when playing various games.

Further, in the above embodiment, the case where the goal-in time of the player car is calculated has been described as an example, but other than this, some points for lap time measurement are prepared in the middle of the racing course. The time at the time when this point is passed may be similarly obtained by the correction calculation.

Further, in the embodiment, the case where the player car moves along a predetermined racing course has been described as an example, but the present invention is not limited to this, and the player car may take an arbitrary route in the game space as a final goal. It is also possible to apply to a game in which the player moves while aiming at and corrects the goal-in time using the above-described method.
