In this way, in this embodiment, FIG.
The fighter 530 moves under the control of the player in the predetermined three-dimensional game space set as shown in FIG. 2 and the player attacks the enemy fighter 532, and the calculation result is output to the image composition unit 200. .

In the game device of this embodiment, the image is supplied to the display every 1/60 seconds, so the game space calculation section 110 performs the above-mentioned calculation every 1/60 seconds, and the information thereof is used as the image composition section 200. Is output to.

The image synthesizing unit 200 is a game calculation unit 100.
The pseudo three-dimensional image and the radar image actually seen by the player are formed according to the calculation result of 1. and displayed on the display 30.
And an image drawing unit 240 and an object image information storage unit 260.

The object image information storage section 260 stores image information of a moving object such as a fighter designated by the object number and image information of the ground, mountains, enemy bases and the like.

In this case, these pieces of image information are expressed as a set of a plurality of polygons. For example, as shown in FIG. 6, a moving object 510 such as a fighter is represented by a set of polygons 512-1, 512-2, 512-3 ... And these polygons 512-1 to 51
The image information including the vertex coordinates of 2-3, etc. is stored in the object image information storage unit 260. Similarly,

It is stored in 0.

The three-dimensional operation unit 220 reads out corresponding image information from the object image information storage unit 260 based on the input data (moving body information, division map information, etc.) and enters the game space as a set of a plurality of polygons. Set. At this time, a process for obtaining the vertex coordinates in the viewpoint coordinate system of the set of polygons forming each object is performed from the position information of each object input in the world coordinate system. That is, since the output coordinates of the game space calculation unit are the world coordinate system, coordinate conversion is performed to the viewpoint coordinate system. Then, processing such as clipping processing for removing data outside the field of view, perspective projection conversion to the screen coordinate system, and sorting processing is performed, and the processed data is output to the image drawing unit 240.

The image drawing section 240 forms image information that should be actually seen by the player from these input data. That is, since the data input from the three-dimensional calculation unit 220 is expressed as image information including the vertex information of the polygon, the image drawing unit 240 uses the vertex information of the polygon and the like to determine all dots inside the polygon. Image information is formed. Then, the processed data is output to the display 30 as shown in FIG.
A virtual three-dimensional game image as shown in (B) is formed.

As a calculation method of image synthesis in the image drawing unit 240, the contour line of the polygon is obtained from the vertex coordinates of the polygon, the contour point pair which is the intersection of the contour line and the scanning line is obtained, and the contour point is calculated. A method of associating the line formed by the pair with predetermined color data or the like may be used. In addition, the image information of all the dots in each polygon is stored in advance in a ROM or the like as texture information, and the texture coordinates given to each vertex of the polygon are used as an address to read and paste the texture information. A so-called method may be used.

FIG. 6 shows a principle diagram of the three-dimensional image synthesizing method.

In the game device of the embodiment, the map information in the three-dimensional game space 500 and the three-dimensional game space 50 are stored.
Information about the three-dimensional object 510 appearing in 0 is stored in advance in the map information storage unit 130 and the moving body information storage unit 140 in the game calculation unit 100.

Further, the image information regarding the three-dimensional object 510 includes a plurality of polygons 512-1, 512-512.

Taking the fighter game of this embodiment as an example, 3
The three-dimensional object 510 is an enemy fighter 532 or the like that appears in the three-dimensional game space 500.
In addition to this, various three-dimensional objects representing the background such as the ground 519, the mountain 520, the building 522, the base 524, and the like are arranged in 00 as shown in FIG.

These three-dimensional objects are perspective-projected by the image synthesizing unit 200 onto the perspective projection plane 620 of the viewpoint coordinate system centered on the viewpoint 610 of the virtual player P, and are displayed on the display 30 as a pseudo three-dimensional image 522. Is displayed.

In FIG. 7, a fighter 530 operated by a player and an enemy fighter 5 in the three-dimensional game space 500.
The positional relationship with 32 is shown. 3D game space 5
00 is, in principle, the world coordinate system (XW, YW, ZW
), In the figure, a viewpoint coordinate system in which a viewpoint 610 shown in FIG. 6 is set at the position of the cockpit of the fighter 530 operated by the player is shown. This viewpoint coordinate system is
The direction of the line of sight of the viewpoint 610 is defined as the z-axis, the horizontal direction is defined as the x-axis, and the vertical direction is defined as the y-axis. Therefore, when the player faces the operation unit 40, the viewpoint 6
When viewing the display 30 from 10, an image can be seen in which one sits in the cockpit of a fighter and is located in the three-dimensional game space 500.

When the player operates the operation lever 14 or the like to rotate or translate the fighter that he or she virtually rides, the viewpoint 6 for the three-dimensional game space 500 is displayed.
The position of 10 changes, the three-dimensional game space 500 rotates,
It will be translated. Therefore, the game calculation unit 100
3 based on this operation signal and game program.
Calculations such as rotation and translation of the three-dimensional object 510, which is a fighter, and other three-dimensional objects that constitute the three-dimensional game space 500 are performed in real time. Then, in the image composition unit 200, these three-dimensional objects are perspective-projected on the perspective projection plane 620 and displayed on the display 30 as a pseudo three-dimensional image 522 that changes in real time.

When the 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 in the positive direction of the z-axis, and each coordinate is perspective-projected into the screen coordinate system which is the projection surface 620. 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 30. Therefore, the player 600 can virtually simulate a state in which the player is moving in the three-dimensional game space 500 while operating a fighter by operating the levers 14 and 16.

In the arcade game machine of the embodiment, when the game is started, the fighter operated by the player freely fly around the virtual three-dimensional game space 500 shown in FIG. 5, and the enemy fighter 532 and the enemy base 524. Etc. with a Balkan gun or missile.

On the other hand, the enemy fighter 532 also moves back and forth within the three-dimensional game space 500 in accordance with a preprogrammed algorithm, and particularly frequently flies around the player fighter 530 and has a limited playing time. It is devised so that the number of opportunities to compete with the player fighter 530 increases. The performances corresponding to the types of the moving body and the player moving body according to the types of fighters, bombers, etc. are predetermined by a program. Performance refers to what determines the athletic ability of a moving body, and is specifically the maximum speed and turning ability of the moving body. Further, it is a player's operation input in the case of the player fighter 530 that determines the movement direction, and a preprogrammed algorithm in the case of the enemy fighter 532. Therefore, in the game machine of this embodiment, the movement of the player fighter 530 is determined by its performance and the operation input of the player, and the movement of the enemy fighter 532 is determined by its performance and a pre-programmed algorithm.

FIG. 8 shows the three-dimensional game space 500 in two dimensions of x and z in the viewpoint coordinate system. In the figure, 560 is a visual range of a fighter operated by a player, 564 is an enemy shadow visual range, 562 is a Vulcan effective range, and 566 is a maximum missile range.

Therefore, even if a missile or a Balkan gun is fired at an enemy that is not included in the missile maximum range 566 and the Balkan effective range 562, the enemy cannot be effectively attacked.

FIG. 3 shows a more detailed example of the game screen displayed on the display 30. In the game device of the embodiment, the enemy fighter 532 is located within the view range 560 in the three-dimensional game space 500, and only when the position is before the enemy shadow visual distance 564 shown in FIG. , The image 532 is formed to be displayed on the game screen. Then, the target designator 310 is displayed in an overlapping manner on the display position of the enemy fighter 532. The target designator 310 indicates the position of the enemy, and the enemy fighter 532 is located at the center of the circle. Therefore, the player can easily confirm the enemy fighters existing in the game screen 300 by using the target designator 310.

Further, when the enemy fighter 532 enters the missile range circle 324, the missile seeker 322 is automatically displayed and starts moving toward the enemy fighter 532. Then, when the missile seeker 322 overlaps the target designator 310, the missile is locked on the enemy fighter 532. In this state, when the player operates the trigger button 24 for launching the missile, the missile 582 is launched as shown in FIG. 9, and tracking of the enemy fighter 532 is started. Normally, the missile 582 automatically tracks the enemy fighter 532 and hits the enemy. However, in some cases, the missile launch is detected by the game calculation unit 100, and as shown in FIG. 5
There may be a game effect of releasing the chaff 312 from 32.

With this chaff 312, the missile 582
Whether or not is disturbed depends on the probability, and this probability depends on the game level. If disturbed, missile 58
2 aims at chaff 312 and is shown in FIGS. 9 (A), (B), and (C).
Tracks sequentially as shown in, and explodes at the point of chaff 312.

The vulcan effective range 5 shown in FIG.
When the enemy fighter 532 is positioned within the range of 62, the Balkan gun's aiming point 3 is displayed at the center of the game screen 300 as shown in FIG.
20 is displayed. This Balkan gun sight 320 is used to aim at the enemy fighter 532, and the trigger button 22 for the Balkan gun is operated to fire the Balkan gun toward the enemy fighter as shown in FIG. 10 and shoot it down. be able to.

In the game device of the embodiment, as shown in FIG. 3, the radar image 34 is displayed in the lower left corner of the game screen 300.
Display 0. The radar image 340 displays an enemy symbol 532s representing the position of the enemy fighter 532 flying around the player fighter. Here, 542 is
It is a battle area between player fighters and enemy fighters.
Reference numeral 4 represents a visual range in front of the player fighter 530.
The player fighter 530 can attack only the enemy in the battle area 542, and the game screen 300
Only the enemy fighters 532 located within the view area 544 are displayed above. Therefore, when the enemy fighter does not exist in the game screen 300, the player may use the radar 340 to find the position of the enemy fighter, track the enemy fighter 532, and attack it.

Further, the number of remaining attacking items 350 held is displayed in the lower right corner of the game screen 300, and the remaining game time 330 is displayed in the upper corner of the game screen 300.

By the way, in this type of game, the player has to select an attack target from the flying enemy fighters so that as many enemies as possible can be shot down within the game time. If the player selects an enemy that does not exist, it will not be easy to shoot down the enemy, and the advanced functions of the fighter equipped in this embodiment will not be used well The game ends without being able to enjoy various situations. Therefore, selecting an appropriate enemy is an important factor that affects the fun of the game.

Therefore, in the game device of this embodiment, the enemy fighter 5 to be attacked by the Vulcan gun or the missile is used.
In order to make it easier for the player to select 32, the game space operation unit 110 is provided with a target selection unit 122, selects the most suitable target to attack from a plurality of targets, and identifies this as the optimum target. It is configured to display.

The target selection unit 122 is preset with selection conditions for selecting the optimum target most suitable for attacking. And the three-dimensional game space 50
Based on the selection condition, the enemy fighter 532 corresponding to the optimum target is selected from the plurality of enemy fighters 532 existing in 0, and the selected enemy fighter 532 is passed through the image synthesis unit 200. And is displayed on the display 30 so that it can be distinguished from other enemy fighters.

As in this embodiment, the three-dimensional game space 50
In shooting games with 0, distance and positional relationship are the most important target selection factors. And the selection of the optimum target based on these elements is highly effective in the game production.

Therefore, the embodiment game space calculation unit 110 is used.
Based on the data of the mobile unit information storage unit 140 and the like, each mobile unit (for example, the player fighter 530 and the enemy fighter 53).
A position detection unit 120 is provided which calculates information such as the relative position in the 3D game space 2) and the distance between the player fighter 530 and each enemy fighter 532.

FIG. 11 shows the target selection unit 1
22 and a functional block diagram of the position detection unit 120 are shown. In the actual device, the game space calculation unit 11
0 indicates the position detection unit 12 according to a predetermined program.
0, the target select section 122 is formed.

The target selection section 122 includes an optimum target detection section 124, a change determination section 126 and an identification display section 12.
8. The missile seeker generating unit 130 is included.

The optimum target detection unit 124 selects the optimum target suitable for the most attack from a plurality of targets existing in the three-dimensional game space 500, and the identification display unit 128, the change determination unit 126 and the missile seeker. Output to the generation unit 130.

The optimum target detection unit 124 of this embodiment, as shown in FIG. 7, for example, has a plurality of enemy fighters 532-1, 532-2, 532-3, around the player's fighter 530.
Position P of the player's fighter 530 when
0 and multiple enemy fighters 532-1, 532-2, 532
The positions P1, P2, P3, ... Of -3, ... Are compared with each other, and the most suitable enemy fighter to attack is detected as an optimum target based on the distance and the positional relationship according to an algorithm described later.

Next, a specific example will be given of a function in which the optimum target detection unit 124 selects a target enemy most suitable for an attack from a plurality of targets based on the positional relationship between the player fighter 530 and another target 532 and the distance. It demonstrates using. FIG. 13 shows the three-dimensional game space 500 in two dimensions of the viewpoint coordinate systems x and z, as in FIG. Also in the figure, 560 is the view range of the fighter operated by the player, 564 is the visual range of the enemy shadow, 562 is the effective range of the Balkans, and 566 is the maximum missile range. Then, T _{1 to} T ₁₂ are targets existing in plural in the three-dimensional game space. Note that, for simplification of description, T _{1 to} T ₁₂ actually have altitudes as y coordinate values, but exist on the xz plane so that the distance from the player can be confirmed by the distance shown on the xz plane. I shall.

The hatched area ODE in FIG. 13 is the range of the so-called missile range circle 324 that the player can confirm on the screen, and it can be said that the target therein is the easiest to attack. Therefore, if the target exists in this range, the optimum target detection unit 124 selects the closest target among the targets existing in this range, and in this case, T ₁ is selected.

However, what if the target existing in the missile range circle 324 was only T ₈ . In such a case, it is preferable to select T ₈ because there is a target that is more easily attacked within the player's field of view, such as T ₂ , than selecting T ₈ . Therefore, in this embodiment, the optimum target detection unit 124 sets a predetermined distance 568 described below to select the target.

In order for the player to attack the target,
The target must be within the Vulcan effective range 562 or within the maximum missile range 566. Also, the player can see the enemy fighter on the screen within the enemy shadow visual distance 564, and beyond the range, it can be confirmed only by the radar. Therefore, it is desirable that the attack target is within the missile maximum range and within the enemy shadow visual range. Therefore, as shown in FIG. 13, a predetermined distance 568 for setting a desired range is set. In this way, by setting the predetermined distance 568, the optimum target detection unit 124 functions to preferentially select the target if the target exists within the predetermined distance.

In FIG. 13, the triangle OGH is the visual field range 570 of the player, and therefore the fan-shaped OCF up to the enemy shadow visual distance 564 is the visual range within the visual field of the player, and as described above, on the screen. This part is also displayed in. Therefore missile range circle 32
If there is no target within the predetermined distance within 4, the target within the predetermined distance on the screen, that is, within the range represented by the fan-shaped OIJ is suitable as the attack target.

In this way, the missile range circle 32
If there are targets T ₁ and T 4 within ₄ , the closest one is selected because it is within the predetermined distance 568. However, if the target within the missile range circle 324 is only T ₈ , the predetermined distance is displayed within the screen. Works to select the one in. In this case, assuming that the targets are T ₂ , T ₃ , and T ₈ , the optimum target detection unit 124 selects the closest T ₂ among T ₂ and T ₃ within the predetermined distance on the screen.

Further, when there is no target existing within the missile range circle 324 or within the screen within a predetermined distance, that is, when the target existing in the three-dimensional space is T _{5 to} T ₇ , the optimum target detection unit 124 Is the closest target T ₆
Select

If the target existing in the three-dimensional space is T ₈ ~
If only T ₁₂ is not present within a predetermined distance,
Optimum target detection unit 124 as the most likely attack in T ₈ through T _12, selects the closest T ₈ from the player.

The optimum target detecting section 124 is formed so that once the optimum target is detected, the optimum target is continuously output until the change determining section 126 outputs a change command.

FIG. 14 shows a concrete procedure of the optimum target detecting operation of the optimum target detecting section 124, which will be described later in detail.

The identification display unit 128 displays the selected optimum target in the game screen 300 so that it can be distinguished from other targets.

FIG. 12 shows a state of the display effect screen displayed by the identification display unit 128. FIG. 12A shows the selected enemy fighter 5 to show that the selection has been made.
The display color of the target designator 310-1 of 32-1 and the enemy symbol 532-1s of the enemy fighter 532-1 on the radar 340 are blinking.

FIG. 12B shows the selected enemy fighter 532.
When -1 is out of the screen, the arrow target designator 370 is displayed to show the direction of the enemy fighter 532-1. At this time, another enemy fighter 532 exists in the screen, and if the new enemy fighter 532 is captured in the screen for a certain period of time or more, that new fighter is selected and the enemy fighter 532 is displayed. The display as shown in 12 (A) is performed.

FIG. 12C shows the enemy fighter 5 in the screen.
When 32-2 and 532-3 are extremely distant and the enemy fighter 532-1 at a closer distance exists outside the field of view, the enemy fighter 532-1 at the closer distance is selectively displayed. As described above, since the view range 560 shown in FIG. 8 is displayed on the screen, it is not displayed on the screen when the enemy fighter 531-1 is outside the range. However, in the case of FIG. 12C, since the enemy fighters 532-2 and 532-3 in the screen are extremely far, the radar 3
The enemy fighter 532-1 (not shown) shown as the enemy symbol 532-1s on 40 is the target most easily attacked.
Therefore, by displaying the arrow target designator 370 and blinking the enemy symbol 532-1s on the radar 340, the player is informed that the target most easily attacked exists outside the player's field of view.

FIG. 16 is a flow chart showing a concrete procedure for identifying and displaying the optimum target, the details of which will be described later.

Further, the change determining unit 126 sets the optimum target changing conditions in advance, and when the optimum target currently being identified and displayed corresponds to the change condition, the optimum target detecting unit 12
4 to output a change command.

That is, when the optimum target detected by the optimum target detecting section 124 changes rapidly in a short time,
After all, the player does not know which optimum target should be pursued, and as a result, it is no different from the case where the optimum target is not displayed. In order to prevent such a situation, the optimal target detection part 124 will continue to identify and display the optimal target on a game screen, if one optimal target is detected. Then, when the change condition determination unit 126 determines that the optimum target currently being identified and displayed is not suitable for continuing to be displayed as the optimum target, the change condition determination unit 126 outputs the change command to the optimum target detection unit 124. The optimum target detection unit 124 newly detects the next optimum target that is optimum at that time, and identifies and displays it on the game screen.

At this time, the change conditions can be set as appropriate depending on the game contents and the like, but in the present embodiment, when the optimum target is shot down immediately after the start of the game or the target no longer exists, or the optimum condition is set. The change condition is set when the target disappears from the game screen 300 and a certain period of time elapses, or when the optimum target moves away from the player fighter. In FIG.
An example of a specific operation procedure of the change determination unit 126 is shown, and the contents will be described later.

The missile seeker generator 130 is shown in FIG.
The enemy fighter 53 in the missile range circle 324 shown in
When 2 is entered, a game effect is displayed in which the missile seeker 322 is automatically displayed on the game screen. At this time, when a plurality of enemy fighters 532 are present in the missile range circle 324, the missile seeker 322 is moved to target the enemy fighter selected by the optimum target detection unit 124, and the missile seeker 322 is It is configured to complete the lock-on when it overlaps the target designator 310 of the optimal target.

FIG. 14 is a flow chart when the optimum target detecting section 124 performs the optimum target selecting operation as described above.

In order to select the target that is most likely to attack, the optimum target detection unit 124 first detects whether or not there is a target within the predetermined distance 568 from the targets existing in the three-dimensional space 500. (Step 10). If there is no target existing within the predetermined distance 568, the closest target is selected from the targets existing outside the predetermined distance 568 (step 70).

When the target is present within the predetermined distance 568, in order to select the target that is most easily attacked,
It is detected whether or not there is a target existing within the missile range circle 324 (step 20). Predetermined distance 56
If there is a target existing within the missile range circle 324 within 8, the closest target is selected (step 60).

When there is no target existing within the missile range circle 324 within the predetermined distance 568, next, it is detected whether or not there is a target existing within the screen within the predetermined distance as the target most easily attacked. (Step 30). If there is a target within the screen 300 within the predetermined distance 568, the closest target is selected (step 5).
0). If there is no target within the screen 300 within the predetermined distance 568, the closest target within the predetermined distance 568 is selected (step 40).

Then, the optimum target detecting section 124 selects the enemy fighter 532 which is the optimum target once in step 40, 50, 60 or 70, and then the change determining section 12
Until the command for changing the optimum target is input from 6, the optimum target is not changed. Then, when an instruction to change the optimum target is input from the change determination unit 126 (step 9
0), according to the procedure of steps 10 to 70, the next new optimum target is selected.

Such processing is repeated until the game over is detected (step 80).

FIG. 15 is a flowchart showing an algorithm in which the change determination unit 126 determines the change of the optimum target. The change determination unit 126 receives the data of the optimum target that is most easily attacked, which is detected by the optimum target detection unit 124 by the processing of FIG. 14 described above, and performs the following processing.

The change determination unit 126 is connected to the optimum target detection unit 12
4 and the data from the position detection unit 120, it is determined whether or not there is an optimum target which is currently being identified and displayed (step 110). In the case of this embodiment, the optimum target is always displayed during the game. Therefore, the state in which the optimum target is not displayed is that immediately after the game starts or when the enemy fighter 532, which is the optimum target, is shot down. In such a case, the change determination unit 126 outputs a change command to the optimum target detection unit 124 (step 150).

If there is something that has already been identified and displayed on the screen, it is judged whether or not the optimum target exists within the screen (step 120).

If it exists on the screen, the optimum target is not changed (step 170).

If it does not exist in the screen, it is judged whether or not another target is captured in the screen for a certain period of time based on the data received from the position detecting unit 120 (step 13).
0). If not, no change in optimal target is made (step 170).

When another target is captured within the screen for a certain period of time, a change command is output (step 150) and the other target is changed to a new optimum target.

In steps 120 and 130, an optimum target change command may be output when the current optimum target does not meet the selection conditions such as the fixed time and the distance regardless of the screen display. .

Such processing is repeated until the game over is detected (step 180).

FIG. 16 is a flowchart showing the identification display algorithm of the identification display unit 128.

The identification display section 128 is the optimum target detection section 12
4 and the output signals of the position detection unit 120, it is determined whether or not the optimum target exists in the game screen (steps 210 and 260).

In the identification display section 128 of the embodiment, first, the judgment of step 210 is performed. In the determination of step 210, for example, as shown in FIG. 12A, the display color of the target designator 310-1 of the enemy fighter 532-1 selected as the optimum target is changed (step 240), and the radar 340 is displayed. Upper enemy fighter 532-1 enemy symbol 53
Blink 2-1s (step 250).

Thereafter, when the selected enemy fighter 532-1 is out of the screen (step 260), FIG. 12 (B)
As shown in, the arrow target designator 370 is displayed to give an effect of notifying the direction of the target (step 270).

In addition, in the judgment of step 210, FIG.
As shown in (C), when the enemy fighter 532-1 selected as the optimum target is out of the screen, the arrow target designator 370 is displayed to inform the direction of the target (step 220) on the radar 340. Enemy symbol 532-1s
Are bled (step 230).

The identification display unit 128 performs such processing
Repeat until the game is over (Step 28
0), the production of the optimal target display is performed.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.
