The battle game was performed by operating the My Ship 530 while viewing the composite image of the enemy aircraft 532 and the like viewed from above.
In such a game device, My Ship 530,
The enemy aircraft 532 and the like are a two-dimensional game field 5
I could only move within 36. Further, the player can see only the composite image viewed from above, that is, the composite image from a predetermined viewpoint position and viewpoint direction.

However, in battles that take place in the real world,
As shown in FIG. 13B, the attack by the enemy aircraft 532 is performed from all directions in 360 degrees in the three-dimensional space. on the other hand,
The player's My Ship 530 can also move freely in a three-dimensional space, thereby providing 36
On the contrary, it is possible to perform an attack on the enemy from all directions 360 degrees while defending against an enemy attack from all directions. And in this way, attack in all directions 360 degrees
In the case of defense, each time the direction is changed, the viewpoint position and viewpoint direction of the player are different, so that the field-of-view image that the player can see is also different.

[0005] As described above, the game space represented by the conventional game device is far from the world experienced by the player in a battle performed in the real world. Further, a game image synthesized by a conventional game device is completely different from a view image that can be seen by a player in a battle performed in the real world. For this reason, the sense of presence, nervousness, and fun of the game could not be further enhanced.

[0006] In order to solve such a problem of the conventional game device, the inventor of the present invention has developed a three-dimensional game device which can freely move around a virtual three-dimensional space by a moving object operated by a player to attack an enemy. We are developing. Here, the virtual three-dimensional space refers to a virtual three-dimensional space formed by the game program.

Now, in such a three-dimensional game device,
Unlike the conventional game in which the My Ship 530 and the enemy aircraft 532 only move around in a two-dimensional range, it is necessary to aim at the enemy (target) in all directions of 360 degrees.
At the same time, when aiming, this is performed while checking own machine's endurance information (target remaining state information) such as own machine's endurance (remaining shield level), own machine's missile number, and the like. It is desired. Therefore, it is desired that such information can be confirmed instantly without moving the line of sight.

BEST MODE FOR CARRYING OUT THE INVENTION

1. First, an example of a three-dimensional game realized by the three-dimensional game device will be briefly described.

According to the present three-dimensional game device, a game in which a virtual three-dimensional space is formed by a preset game program and the player can freely move around in the formed virtual three-dimensional space by a moving body operated by a player. Can provide space.

The three-dimensional game realized by the three-dimensional game device is a future tank game that can be played in a near-future city where various races are gathered. In this futuristic tank game, fighters who have gathered for huge prizes decide the champion in a deathmatch game format in a game field surrounded by walls and not allowed to escape. Each fighter competes for the champion with its own future tank. Then, the player participates in the game as one of these fighters.

FIG. 2 is an external view of the present three-dimensional game apparatus. As shown in the figure, the player 302 operates the left and right analog levers 12 and 14 which are operation units, and
The mobile object projected on T10, that is, the future tank 20 will be operated. That is, the player 302 can freely move forward, backward, left and right in the game field 60 set in the virtual three-dimensional space by operating the future tank 20. The analog levers 12 and 14 are provided with a machine gun that can be fired without any restrictions and triggers 16 and 18 of missiles, which are powerful weapons with a limited number. Further, as shown in FIG. 2, an aim 40 is displayed on the CRT 10, and the player 302 uses the aim 40 to attack an enemy. Further, an enemy position detection radar 50 for detecting the position of the target enemy is displayed on the CRT 10, so that the player 302 can know the enemy position 52 with respect to the own position 51.

FIG. 3 shows an overall view of the game field 60. As shown in the figure, in the game field 60, various terrains that are three-dimensionally set and set by the game program are formed. That is, first,
The four sides of the game field 60 are surrounded by walls 62 so that each fighter cannot escape. A first plateau 64 is provided on the inner periphery of the wall 62. The zero land 66 is surrounded by the first plateau 64, between which slopes 68, 70, 72, 74 are provided. In addition, the zeroland 66 has second and third plateaus 76,
78, and obstacles 80, 82 are also provided. As described above, the game field 60 in the present three-dimensional game corresponds to the conventional two-dimensional game shown in FIGS.
Unlike the game fields 536 and 538 configured in three dimensions, they are configured in three-dimensional terrain. Therefore, a game space full of unprecedented reality can be formed.

The future tank 20 controlled by the player 302 and the future enemy tank 22 controlled by the enemy fighter face each other on the zero zone 66. In FIG. 3, the future tank 2
0 and the enemy future tank 22 between the second and third plateaus 7
6, 78, the player 302
At T10, the enemy future tank 22 cannot be seen. Therefore, the player 302 first finds the enemy position 52 by the enemy position detection radar 50 described above. Then, the future tank 20 is controlled by the analog levers 12 and 14, gets over the second plateau 76, approaches the enemy, and attacks the enemy.

FIG. 4 shows a pseudo three-dimensional image displayed on the CRT 10 when the own future tank 20 approaches the enemy future tank 22 in this manner. Here, the shield display unit 54 displays the shield amounts of the own aircraft and the enemy future tank 22. At present, the shield amount (defense power) of the own aircraft greatly exceeds the shield amount of the enemy future tank 22. Therefore, this is a chance for the player 302 to attack, and conversely, the future enemy tank 22 must avoid this crisis situation and search for an item that recovers the shield amount.

Now, in this case, the player 302 aims at the enemy future tank 22 while watching the aim 40, and makes an attack. Here, the aim 40 is divided into a machine gun aiming unit 41 and a missile aiming unit 42. In addition, the remaining number of missiles 43 is displayed above the aim. Further, a marker 30 is attached to the enemy future tank 22.

The future tank 20 has a machine gun and a missile as weapons, and the aiming of the machine gun is performed by the machine gun aiming unit 41. That is, when the machine gun is fired at the moment when the cross portion of the aiming unit 41 matches the enemy future tank 22, the enemy can be hit with the machine gun.

On the other hand, the aiming of the missile is performed by the missile aiming section 42. However, in this case, the future tank 20 of its own is located on the zero zone 66, and the enemy future tank 2
Since 2 is located on the first plateau 64, there is a height difference between the two. Therefore, the enemy future tank 22 is not located on the extension of the barrel of the future tank 20, and it is difficult to attack with the above-mentioned machine gun. Also, missiles that can only go straight ahead with missile attacks are difficult to hit like machine guns. So book 3
In the three-dimensional game device, the missile has a tracking function. As a result, the enemy future tank 22 becomes the own future tank 20
Missiles can be hit without being on the extension of the gun barrel. And the missile aiming part 42 has shown the standard of the range which can be tracked by this missile.

The remaining number of missiles 43 indicates the number of remaining missiles of the own aircraft, and in this figure, the number of remaining missiles is three. In this case, since the player 302 is now chasing an attack chance and the enemy future tank 22, the line of sight of the player 302 is fixed near the sight 40, and for example, there is a possibility that the missile will be fired even though there is no remaining missile. There is. Therefore, in the present three-dimensional game device, in order to prevent such a situation, the remaining number of missiles 43 is set to the position where the line of sight of the player 302 is
That is, it is arranged near the peripheral portion of the aim 40.

On the other hand, a marker 30 is attached to the enemy future tank 22. This marker 30 indicates that the enemy future tank 22
When it is located within the field of view of the player 302 (within the image display range), it is always stuck. Therefore, the player 302 confirms the position of the enemy by the enemy position detection radar 50 when the future enemy tank 22 is out of the field of view,
When in the visual field range, the position of the enemy can be confirmed by the marker 30.

The marker 30 is usually in the shape of a rectangle, but is deformed into a rhombus in FIG. And
This diamond shape indicates that the enemy future tank 22 has entered the tracking range. That is, while the missile aiming section 42 is a guideline for the tracking range, the deformation of the marker 30 into a diamond shape is based on the calculation of various conditions such as the distance to the enemy, and as a result, the enemy falls within the tracking range. This indicates that there is something, and the display is more accurate. The marker 30 is currently blinking. This blinking indicates that the shield amount of the future enemy tank 22 is extremely small as shown in the shield display section 54. Therefore, the player 30
No. 2 can confirm that now is an attack chance without moving his / her eyes to the shield display unit 54. As described above, in the present three-dimensional game device, the target state information is displayed using the marker 30 so that the player 302 can easily attack the target.

The above description is for a case where only one player plays a game, as shown in FIG. When the player plays the game by himself, the computer is in charge of the fighter who controls the enemy future tank 22. In contrast, in FIG.
An external view of the present three-dimensional game apparatus when two players play against each other is shown. In this case, the player 302
The future tank 20 is controlled while watching the RT 10, and the player 3
03 controls the enemy future tank 22 while watching the CRT 11. On the CRT 10, a pseudo three-dimensional image viewed from the future tank 20 is displayed.
In FIG. 1, a pseudo three-dimensional image viewed from the direction of the enemy future tank 22 is displayed. Then, while viewing pseudo three-dimensional images from different viewpoints in one virtual three-dimensional space, two players play a game under different geographical conditions. Note that FIG.
Although only a case of a human player is shown, the present invention is not limited to this, and can be naturally applied to a case where a game is played by a plurality of players of three or more.

It is stored in the three-dimensional image information storage unit 204 as three-dimensional image information.

In the three-dimensional game device shown in FIG.
A predetermined game space is set in the game space calculation unit 100 based on an operation signal from the operation unit 140 and a preset game program. That is, in the game space calculation unit 100, the positions or positions and directions of all three-dimensional objects constituting the game space are determined in accordance with the operation signal and the game program, and stored in the object information storage unit 104 as object information. . Next, the image synthesizing unit 200 arranges the three-dimensional image information stored in the three-dimensional image information storage unit 204 in the virtual three-dimensional space in the direction specified by the position specified by the object information. In the image calculation unit 202, a pseudo three-dimensional image viewed from the viewpoint position and the viewpoint direction of the player is synthesized from the arranged three-dimensional image information, and the image is output by the CRT 10.

FIG. 9 is a block diagram illustrating an embodiment of the three-dimensional game apparatus in further detail.

In the embodiment shown in detail in FIG. 9, the game space calculation unit 100 further includes a central processing unit 102, a terrain information storage unit 106, and an object information change unit 108. Thereby, a game space in which the terrain information is reflected can be formed. Here, the central processing unit 102 controls the entire three-dimensional game device. Further, a predetermined game program is stored in a storage unit provided in the central processing unit 102. The terrain information storage unit 106 stores terrain information of the game field 60 formed by the above-described three-dimensional terrain, for example, as height data. Also, the object information changing unit 108
In the calculation, the object information stored in the object information storage unit 104 is changed at any time based on the terrain information stored in the terrain information storage unit 106.

Further, in the three-dimensional game device shown in detail in FIG. 9, the image synthesizing section 200 further includes a frame image forming section 180, and the image calculating section 202 includes
It includes an image supply unit 212 and an image forming unit 240.

The frame image forming section 180 forms an image of the marker 30 and the aim 40 set by the marker setting section 150 and the aim setting section 170 as a two-dimensional frame image.

The image supply section 212 includes a processing section 214 for controlling the entire image synthesis section 200, a coordinate conversion section 216 for performing three-dimensional arithmetic processing on image information such as vertex coordinates of polygons, and a clipping processing section 218. It is configured to include a perspective conversion unit 220 and a sorting processing unit 222.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the image information such as the vertex coordinates of the polygon that has been subjected to the three-dimensional arithmetic processing in step (1), whereby a pseudo three-dimensional image is synthesized. Further, in the image forming unit 240, the two-dimensional frame image formed by the two-dimensional frame image forming unit 180 is image-combined with the pseudo three-dimensional image,
Thereby, the pseudo 3 in which the marker 30 and the aim 40 are displayed
The two-dimensional image is output to the CRT 10.

Next, the operation of the entire three-dimensional game device will be described.

First, at the same time as the game starts, the central processing unit 102 stores the object information, which is the position and direction information of all the three-dimensional objects arranged in the virtual three-dimensional space, in accordance with the game program, in the object information storage unit 104. To memorize. However, this operation is not necessary if a part of the object information storage unit 104 is used as a non-volatile memory and the initial value of the object information is stored in advance.

The object information stored in the object information storage unit 104 is stored, for example, in a format shown in FIG. In the figure, the index (0
To n) are serial numbers representing the three-dimensional objects. For example, index 0 indicates the future tank 20, index 1 indicates the enemy future tank 22, and index 2 indicates the wall 62.
And the index 3 is a serial number representing a three-dimensional object constituting the obstacle 80. This allows, for example,
The position information and the direction (tilt) information of the future tank 20 in the virtual three-dimensional space are (X0, Y0, Z0) and (θ0,
φ0, ρ0). As a result, the position and direction in which the future tank 20 is arranged are determined. Similarly, the position and direction information of the three-dimensional object such as the enemy future tank 22, the obstacle 80, and the like are also set, whereby the position and direction information of all the three-dimensional objects forming the game space in the virtual three-dimensional space are set. Will be determined.

In the case of a large three-dimensional object such as the future tank 20, the object is divided into, for example, a cockpit, a left driving unit, a right driving unit, and a gun barrel, and each of these parts is divided into individual parts. May be considered as a three-dimensional object, and the index may be assigned to the object. In this manner, these parts, for example, the left driving unit, the right driving unit, the barrel, and the like can be independently moved, and a future tank 20 that moves with more reality can be drawn.

The terrain information storage unit 106 stores terrain information of the game field 60 shown in FIG. 3 as, for example, height information. The object information changing unit 108
By reading the terrain information, the position and direction information of the three-dimensional object stored in the object information storage unit 104 can be changed. That is, for example, the position and direction information (X0,
By changing the values of Y0, Z0, θ0, φ0, ρ0), the inclination of the future tank 20 and the like are changed. Thereby, a game space reflecting the terrain information can be formed.

Next, in the marker setting unit 150 and the aim setting unit 170, the display setting of the marker 30 and the aim 40 is set. That is, what form and at which position the marker 30 and the aim 40 are to be displayed is set. The setting information of the marker 30 and the aim 40 is shown in FIG.
Is input to the frame image forming unit 180 as shown in FIG. The frame image forming unit 180 forms a two-dimensional frame image based on the setting information and the like. The formed two-dimensional frame image is superimposed on the pseudo-three-dimensional image by the image forming unit 240, whereby the marker 30 and the aim 40
Is displayed on the pseudo three-dimensional image. The details of the setting of the marker 30 and the aim 40 will be described later.

Next, the operation of the image synthesizing section 200 will be described.

First, the processing unit 214 reads out the position and direction information of the three-dimensional object from the object information storage unit 104 using the above-mentioned index as an address. Similarly, the processing unit 214 reads out the three-dimensional image information of the three-dimensional object from the three-dimensional image information storage unit 204 using the index as an address. For example, when the index is 0, the position and direction information (X0, Y0, Z0, θ0, φ
0, ρ0) is read from the object information storage unit 104, and three-dimensional image information representing the future tank 20 as a set of polygons is read from the three-dimensional image information storage unit 204.

The processing section 214 sequentially reads out the indexes as described above and converts the information into a data format as shown in FIG.

FIG. 7A shows an overall view of this data format. As shown in the figure, the data to be processed is configured such that the object data of all the three-dimensional objects displayed in this frame are continuous with the frame data at the head. After the object data, the polygon data of the polygons constituting the three-dimensional object is further connected. Here, the frame data refers to data formed by parameters that change for each frame, and is information common to all three-dimensional objects in one frame, such as viewpoint position, viewpoint direction, and viewing angle information of the player, and monitor data. , And information such as light source information. These data are set for each frame. For example, when a window or the like is formed on the display screen, different frame data is set for each window. Thereby, for example, a rearview mirror, a screen when the future tank 20 is viewed from above, and the like can be formed on the display screen.

The object data refers to data formed by parameters that change for each three-dimensional object, position information in three-dimensional object units,
It is composed of data such as direction information. This is data having substantially the same contents as the object information described above.

The polygon data refers to data formed by image information of the polygon and the like, and as shown in FIG. 7B, a header, vertex coordinates X0, Y0, Z0 to X3,
It is composed of other attached data such as Y3, Z3, etc.

The coordinate calculation section 216 reads data in the above format and performs various calculation processes on the coordinates of each vertex. Hereinafter, this calculation process will be described with reference to FIG.

For example, taking a future tank game as an example, FIG.
, Three-dimensional objects 300, 332, 334 representing future tanks, enemy future tanks, buildings, obstacles, etc.
They are arranged in a virtual three-dimensional space represented by a world coordinate system (XW, YW, ZW). Thereafter, the image information representing these three-dimensional objects is coordinate-transformed into a viewpoint coordinate system (Xv, Yv, Zv) based on the viewpoint of the player 302.

Next, the clipping processing section 218 performs image processing called so-called clipping processing. Here, the clipping process means image information outside the field of view of the player 302 (or outside the field of view of a window opened in a three-dimensional space), that is, clipping planes 340, 342 at the front, rear, right, lower, left, and upper sides. , 344, 3
Image processing for removing image information outside an area surrounded by 46, 348, and 350 (hereinafter, referred to as a display area 2). That is, the image information required for the subsequent processing by the present apparatus is only the image information within the field of view of the player 302. Therefore, if other information is removed in advance by the clipping process, the load of subsequent processes can be greatly reduced.

Next, in the perspective transformation unit 220, the display area 2
Perspective transformation to the coordinate system (XS, YS) of the screen 306 is performed only on the objects existing in the screen, and data is output to the sorting processing unit 222 at the next stage.

The sorting unit 222 determines the order of processing in the image forming unit 240 at the next stage, and outputs polygon image data in accordance with the order.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the data such as the vertex coordinates of the polygon subjected to the three-dimensional calculation processing. In this case, as a calculation method, a contour line of the polygon is obtained from the coordinates of the vertices of the polygon, a contour point pair which is an intersection of the contour line and the scanning line is obtained, and a line formed by the contour point pair is determined by a predetermined color. You may use the technique of making it correspond to data etc. In addition, a method is used in which image information of all dots in each polygon is stored in advance in a ROM or the like as texture information, and texture coordinates given to each vertex of the polygon are read as an address and pasted. You may.

Finally, the pseudo three-dimensional image formed by the image forming section 340 is output from the CRT 10.

3. Setting of Marker and Setting of Aim Next, setting of the marker 30 and the aim 40 performed by the game space calculation unit 100 will be described in detail.

(1) Marker Setting First, the setting of the marker 30 performed by the three-dimensional game device of the embodiment shown in FIG. 10 will be described in detail.

As shown in FIG. 10, the central processing unit 102 of the three-dimensional game device includes a display area determining unit 110. The display area determination unit 110 determines whether a target, for example, the enemy future tank 22 is present in the display area 2 shown in FIG.

Further, as shown in FIG.
50 is a marker display determination unit 152, a marker position setting unit 1
54. This marker display determination unit 1
In 52, it is determined whether or not to display the marker 30 on the pseudo three-dimensional image according to the determination result of the display area determination unit 110. Further, the marker position setting unit 154
In, the marker display determination unit 152 calculates the display position of the marker 30 determined to be displayed.

Next, the operation of the three-dimensional game device shown in FIG. 10 will be described.

First, the central processing unit 102 reads out at least position information from the object information of the enemy future tank 22 from the object information storage unit 104. Next, the display area determination unit 110, based on the position information,
It is determined whether or not this enemy future tank 22 exists in the display area 2. In other words, the plane equation of the clipping planes 340 to 350 forming the display area 2 includes the enemy future tank 22
Is assigned to the position information V1 (X1, Y1, Z1), and if it is determined that all the clipping planes are within the display area, the enemy future tank 22 is determined to be within the display area 2. You. Specifically, for example, the plane equation of the clipping plane 340 is expressed as h (V) = aX + bY + cZ + d
When h (V1) = aX1 + bY1 + cZ1 + d is calculated, and when h (Vn) .ltoreq.0, it is determined that Vn is in the display area 2 of the clipping plane 340.
If h (Vn)> 0, it is determined that Vn is outside the display area 2. This calculation is performed for all clipping planes 340 to 350. However, for example, the clipping surfaces 340 and 342 may be omitted.

When it is determined that the future enemy tank 22 is in the display area 2, the marker display determination unit 152 determines that the marker 30 is to be displayed on the pseudo three-dimensional image, and the form of the marker 30 to be displayed. Is also determined. Then, the position information of the future enemy tank 22, the information on the form of the marker 30, and other necessary information are output to the marker position setting unit 154.

Next, the marker position setting section 154 determines the setting position of the marker 30 on the pseudo three-dimensional image from the position information of the enemy future tank 22, the position information of the screen 306, and the viewpoint position information of the player 302. It is determined. Specifically, as shown in FIG. 11A, the setting position of the marker 30 is substantially the intersection C of the line connecting the viewpoint A of the player 302 and the position B of the future enemy tank 22 and the screen 306. Is set to By setting this position, even if the viewpoint position and viewpoint direction of the player 302 change, the marker 30 displayed on the pseudo three-dimensional image is always set to the enemy future tank 2
2, it is possible to stick it at the position.

The setting information of the marker 30 set as described above, that is, the form information and the position information of the marker 30 are:
The image is output to the frame image forming unit 180. Then, a two-dimensional frame image is formed, and the marker 30 is displayed by overlapping the pseudo three-dimensional image.

FIG. 12A shows an example of a pseudo three-dimensional image on which the marker 30 is displayed in this manner. The figure shows a scene in which the own future tank 20 is chasing the enemy future tank 22 near the wall 62. Since the enemy future tank 22 has almost no shield amount as shown in the shield display section 54, the enemy future tank 22 escapes to avoid an attack. Even in this case, since the marker 30 is attached to the enemy future tank 22, the player can easily catch the enemy. FIG. 12B shows a scene in a case where the enemy future tank 22 has subsequently escaped. In this case, the marker 30 is not displayed because the enemy future tank 22 no longer exists in the display area 2.

FIGS. 13A and 13B show the most characteristic scenes in which the effectiveness of the marker setting according to this embodiment appears. In FIG. 7A, the enemy future tank 22 is trying to escape behind the obstacle 82 in order to avoid an attack from the future tank 20. In this case, the marker 30 is attached to the enemy future tank 22 because the future enemy tank 22 exists in the display area 2.

FIG. 9B shows the enemy future tank 22
Shows a scene in the case where the player has escaped behind the obstacle 82. Then, even when the view of the enemy future tank 22 is blocked by the obstacle 82, the marker 30 is displayed at a position corresponding to the position of the enemy future tank 22 as shown in FIG. I have. As described above, according to the marker setting according to the configuration of the present embodiment, the marker 30 is always displayed at a position corresponding to the position of the target even if the field of view for the target is blocked. Therefore, the player can grasp the position of the enemy even after being escaped by the enemy, and can easily track the enemy. In the present embodiment, the obstacle 82 is configured to be destroyable by a missile.
The player can also attack the enemy again after destroying the obstacle 82 with the missile and the enemy can be seen.

As another method of finding an enemy when the enemy has escaped in this way, it is conceivable to perform tracking by using an enemy position detection radar 50 shown in FIG. However, the enemy position detection radar 50 can only grasp the approximate distance and direction to the enemy. Therefore, it is difficult to grasp whether the enemy is behind the obstacle 82 like the marker 30. Also,
In such an enemy position detection radar 50, the line of sight must be temporarily moved from the aim 40 in order to confirm the radar. Then, after moving the line of sight, the relationship between the own position 51 and the enemy position 52 must be grasped by looking at the radar. However, in a state where the enemy is being tracked in this way, usually, the player cannot afford to look at the radar in this way and further grasp the relationship between the own position 51 and the enemy position 52. Normal. Therefore, in such a case, the enemy position radar 50 is useless.

On the other hand, in the case of the marker 30 shown in FIG. 13B, the enemy position can be ascertained only by searching for the marker 30 on the screen. It is. Further, it is possible to recognize not only the rough position and direction of the enemy but also that the enemy is hidden by the obstacle 82. Further, in such a situation where the enemy is pursuing the enemy, the sight 40 of the own aircraft and the enemy future tank 22 are usually located at substantially the same position. According to this embodiment, the marker 30 is attached to the enemy future tank 22. Therefore, the player can simultaneously see the sight 40 of his own aircraft, the enemy future tank 22, and the marker 30 on the same line of sight. As a result, there is no need to shift the line of sight as in the case where the enemy position radar 50 is used. From the above, it can be understood that the aiming system according to the present embodiment is very excellent and is most suitable as the aiming system in such a three-dimensional game space.

FIGS. 14 (A) and 14 (B) show that the field of view of
The scene interrupted by the fog 24 is shown. In this way, even when the field of view is blocked by the fog 24, according to the configuration of the present embodiment, the marker 30 is always attached to the enemy as shown in FIG. FIG. 2B shows a scene in which the future enemy tank 22 comes out of the fog 24. Since the marker 30 is attached to the player even when the enemy is not visible as shown in FIG. 10A, even if the enemy future tank 22 suddenly comes out as shown in FIG. Aiming at the enemy can be achieved.

FIGS. 14 (A) and 14 (B) show the case where the fog 24 obstructs the field of view.
Even when the field of view is obstructed by snow, rain, or the like, the player can easily aim at the enemy 40 because the marker 30 is always attached to the enemy, as shown in FIG.

FIG. 15 is a block diagram of the embodiment when fog, darkness at night, and the like are represented on the virtual three-dimensional space. Hereinafter, this will be briefly described.

The embodiment shown in FIG. 15 is different from the embodiment shown in FIG. 9 in that a visibility condition setting unit 190, a pallet number changing unit 192, and a color code changing unit 194 are newly added. Further, FIG.
Also shown is a color pallet section 196 that is contained within 0.

[0086] The visibility condition setting section 190 sets the visibility condition of the game field in which the game is played every time the game is started. That is, if the game surface selected by the player is a fog surface, the fog game field is
In the case of the night side, the setting of the night game field is performed.

As shown in FIG. 16, for example, eight (0 to 7) color palettes are built in the color palette section 196. As shown in the figure, the palette number is an address for specifying which of the eight color palettes is to be selected, and the color number is an address for specifying which color code of the color palette is to be selected. is there. The color palette unit 196 can output, for example, an 8-bit color code for each of R, G, and B by specifying these addresses.

In the pallet number changing unit 192, according to the visibility setting data from the visibility setting unit 190,
A pallet number used for the polygons forming the pseudo three-dimensional image is set and changed for each polygon. Specifically, a pallet number to be used for the polygon is set according to the distance between itself and the polygon to be processed.

At the start of the game, the color code changing section 194 changes the color code in each color palette according to the visibility setting data from the visibility setting section 190. That is, if fog visibility is set,
The color code of the color palette is changed so that the color becomes closer to white as the distance from the player increases.

Next, the operation of this embodiment will be briefly described by taking as an example the case where the fog visibility is set.

In order to represent the visibility of the fog, the color data of each polygon may be specified so that the colors of all the polygons become closer to white as the distance increases. That is, the actual color of a certain polygon is, for example, an RGB color code (17
0, 65, 30). Then, in the fog visibility situation, the color of this polygon needs to approach white as the distance from the player increases, and a code in which all of RGB are equal at the farthest position, for example, (100, 10)
0, 100). Therefore, in the present embodiment, the color code changing unit 194 changes the value of the color code in the color pallet as shown in FIG. As shown in the figure, it is understood that the value of the color code (170, 65, 30) gradually approaches white (100, 100, 100). Similarly, the color codes corresponding to the other color numbers are similarly changed. These color codes are changed each time the player selects the game surface at the start of the game and the setting of the visibility state is changed.

In FIG. 16, the color palette 0
Is a color palette used for the polygon closest to the own machine, and conversely, the color palette 7 is a color palette used for the polygon farthest. The color palettes 2 to 6 are color palettes used for polygons located at a distance between them, and are previously associated with each other according to the distance.

A palette number changing unit 192 sets which palette number of each polygon is used by each polygon. That is, first, the pallet number changing unit 192 calculates the distance between the own machine and the polygon. However, this distance data is stored in the image supply unit 212.
This data is required in the sorting processing performed in step (1), and this data is used in this embodiment. Next, it is determined which palette number of the palette number is to be used according to the distance, that is, which color palette is to be used in FIG. Once determined, the color code used for all the dots in the polygon is specified by the palette number and the color number given in advance to each polygon, and the color corresponding to the color code in the polygon is specified. All dots will be filled.

In the view condition setting unit 190, the color code of the color palette unit 196 is changed by the color code change unit 194 according to the selected surface of the player, and the view condition is set. To give a specific example, the code of the color palette at the farthest position in the case of fog is, for example, (1
00, 100, 100), and at night, for example, (0, 0, 0). In the case of sunset (2
00, 50, 30) to slightly enhance the red color. Also,
Regarding the sea, the deep sea is (0, 0, 50), which is close to blue, and the shallow sea is (50, 50, 200), which makes the blue more intense. Also, for example, if the place where you play the future tank game is a green planet, add a little green to the fog element,
If it is a sandstorm, add a little yellow.

As described above, according to the embodiment shown in FIG. 15, various view conditions can be set.

In the embodiment described above, the marker 3
0, the image display of the aim 40 is performed by the frame image forming unit 180.
, A two-dimensional frame image is formed, and this is superimposed on the pseudo three-dimensional image by the image forming unit 240 for display. However, this display can also be performed by the embodiment having the configuration shown in FIG. 17, for example. In the embodiment shown in FIG. 17, the marker 3 is stored in the object information storage unit 104 by the settings of the marker setting unit 150 and the aim setting unit 170.
By generating object information of the three-dimensional object corresponding to 0 and the aim 40, the images of the marker 30 and the aim 40 are displayed. In this case, the position information of the marker 30 is set to the position on the pseudo three-dimensional image corresponding to the position of the future enemy tank 22, that is, the position of the point C in FIG. The position information of the aim 40 is set by setting it at a substantially central portion on the screen. By setting in this manner, for example, when the future enemy tank 22 is in the display area 2, the marker 30 is displayed at the position of the point C in FIG. 11A by the perspective transformation by the perspective transformation unit 220. Will be. On the other hand, if the future enemy tank 22 is not in the display area 2,
Clipped out by the clipping processing unit 218,
It will not be displayed.

(2) Change of Marker Shape, etc. FIG. 18 shows a marker 3 based on the target state information of the target.
FIG. 3 is a block diagram of an embodiment in the case of changing and displaying the shape or color of 0 or a combination thereof.

As shown in the figure, this embodiment has a configuration in which a marker changing unit 156 and a target state information calculation unit 112 are newly added to the embodiment shown in FIG.

Here, the target state information calculating section 112 is built in, for example, the central processing section 102, calculates target state information, and outputs this to the marker changing section 156. Here, the target status information includes, for example, the remaining durability against the target's attack, whether or not the target is within the tracking range of the missile, the number of the remaining missiles owned by the target, the direction in which the target is facing, the target and the target. Information such as the distance to the aircraft can be considered.

The marker changing section 156 changes the shape or color of the marker 30 or the combination thereof in accordance with the target state information.

Hereinafter, the operation of this embodiment will be briefly described with reference to FIG.

First, similarly to the embodiment shown in FIG. 10, the enemy future tank 22 is displayed in the display area 2 by the display area determination section 110.
It is determined whether or not there is in, based on the result,
The marker display determination section 152 determines whether or not to display the marker 30. Thereafter, the marker position setting unit 154
In, the position at which the marker 30 is displayed is calculated.

Next, the target state information calculation unit 112 provided in the central processing unit 102 calculates the target state information of the target, that is, the enemy future tank 22. Then, based on the target state information, the marker changing unit 156 changes the shape and the like of the marker. For example, in FIG. 19A, based on the target state information that the enemy future tank 22 is within the missile tracking range from the target state information calculation unit 112,
The marker changing unit 156 changes the shape of the marker 30 from a square to a diamond. Thus, in this embodiment,
Target state information can be visually conveyed to the player by a change in the shape or the like of the marker 30. As a result, the player can immediately grasp the state of the enemy and can immediately take the next action, so that an optimal aiming system is used in a shooting game in which the situation changes rapidly. Also,
The marker 30 is always stuck to the enemy future tank 22 as described above. Therefore, by expressing the target state information using the marker 30 attached to the enemy, the player does not need to move his / her line of sight in another direction to check the target state information. As a result, the player can concentrate more on aiming at the enemy, so that the attack becomes very simple, and it is understood that this aiming system is a very excellent aiming system.

FIG. 19B shows a scene in which a missile 98 fired by the own aircraft hits an enemy and a fire column 99 is generated. As a result, as shown in the shield display section 54 in FIG. 19C, the shield amount of the enemy is greatly reduced, and the enemy is destroyed by another missile attack.

At this time, from the target state information calculation unit 112,
Target state information indicating the durability against the attack of the enemy future tank 22 is input to the marker changing unit 156, and the marker changing unit 15
6 makes the marker 30 blink red and white as shown in FIGS. 19 (c) and (d). By making the marker 30 blink red and white as described above,
The player can visually and easily understand that the future enemy tank 22 can be destroyed by another attack,
You will be immediately attacked by the next attack.

Other than this, the color of the marker 30 may be sequentially changed from blue to red, for example, in accordance with the remaining durability of the enemy. As a result, the player can visually grasp the state of the enemy immediately, and can immediately determine whether it is time to attack or defend.

Further, for example, the shape or the like of the marker 30 may be changed in the marker changing unit 156 based on the target state information regarding the direction in which the enemy is facing. In this case, the target state information can be visually represented by representing the shape of the marker 30 with, for example, an arrow indicating the direction in which the enemy is facing. This allows the player to immediately grasp the direction of the enemy, and if the enemy's barrel is not facing the ship's own direction, attack immediately as a chance to attack, and conversely, the enemy's barrel is facing When the aircraft's shield level is low, you can immediately take action to escape.

Further, the target state information, which is the remaining number of missiles of the enemy future tank 22, for example, can be visually represented by being arranged around the marker 30 in the form of a figure in the form of a missile, for example. .

FIGS. 20A and 20B show examples in which the shape of the marker and the display position of the marker 30 are changed based on the position information of the enemy. This example is shown in FIG.
This corresponds to (A) and (B). That is, in FIG. 12 (B), when the future enemy tank 22 goes out of the display area 2, the marker 30 is no longer displayed,
To grasp the enemy position 52, the player has no other method but to use the enemy position detection radar 50. In contrast,
In FIG. 20B, when the future enemy tank 22 has moved out of the display area 2, the marker 30 is located at a position M on the periphery of the screen corresponding to the direction in which the future enemy tank 22 exists.
Is displayed. Further, in this case, by changing the shape of the marker 30 to a shape indicating the direction of the enemy future tank 22, the player can visually grasp the direction of the enemy. FIGS. 11A and 11B schematically show the above marker setting method. By this marker setting, the player can easily grasp the position of the enemy irrespective of whether or not the enemy future tank 22 is present in the display area 2. In particular, as shown in FIGS.
The marker 30 is displayed at the point M where the enemy is out of the field of view. Therefore, the player who has been following the movement of the enemy future tank 22 with his or her eyes does not need to move his line of sight to, for example, the position of the enemy position detection radar 50 in order to confirm the position of the enemy again. As a result, it is possible to continuously chase and attack the enemy future tank 22 without changing the direction of the line of sight.

As shown in FIGS. 19A and 19B, in this embodiment, the missile 98 has a tracking function. Hereinafter, the tracking function of this missile will be described with reference to FIG.
This will be briefly described with reference to the embodiment shown in FIG.

In the embodiment shown in FIG. 21, the terrain information stored in the terrain information storage unit 106 can be reflected in the calculation of the movement position of the bullet by the bullet movement calculation unit 122 and the hit determination by the hit determination unit 126. It has become. If the configuration is such that the three-dimensional topographical information can be reflected in the movement position and hit determination of the bullet, there is a problem that the aiming operation of the bullet becomes more difficult than before. If the game configuration is such that the attacker does not easily hit the bullet, the game does not progress, and a three-dimensional game full of speed cannot be provided. Therefore, in this embodiment, a new bullet tracking system is provided to solve this problem.

FIG. 21 is a block diagram showing an embodiment in which a tracking system is provided for a bullet as described above. FIG.
18 is different from the embodiment shown in FIG. 18 in that a trigger determination unit 142 and a bullet processing unit 120 are newly added.

The trigger determination section 142 determines whether or not the player has triggered a bullet, thereby forming a bullet firing signal. Here, the bullets are not limited to machine guns and missiles used in the present three-dimensional game, but include all types of weapons such as light guns such as lasers, axes, and arrows.

The bullet processing unit 120 includes a bullet movement calculating unit 122,
The configuration includes a tracking movement calculation unit 124 and a hit determination unit 126. The bullet movement calculation unit 122 calculates the movement position of the bullet from the object information of the moving object changed by the object information changing unit 108 and the firing signal of the bullet from the trigger determination unit 142. The tracking movement calculation unit 124 performs calculation for changing the movement position of the bullet so as to track the target.

In the hit judging section 126, the object information of the target, for example, the enemy future tank 22, is read from the object information storage section 104.
A bullet hit determination is performed based on the bullet movement position changed by the tracking movement calculation unit 124. When a bullet hits,
This hit determination information is stored in the object information storage unit 104.
Is reflected in the object information of various three-dimensional objects stored in.

Next, the operation of this embodiment will be described.

First, the object information change unit 108 performs a change calculation of the object information of the moving object, that is, the future tank 20, using the terrain data stored in the terrain information storage unit 106.

In this state, when the player operates the triggers 16 and 18 connected to the operation unit 140, the trigger operation signal is input to the trigger determination unit 142 via the operation unit 140. Then, the trigger determining unit 142 determines whether or not the machine gun or the missile has been triggered, and if it is determined that the trigger has been performed, a firing signal of the machine gun or the missile is formed. Output to the unit 122.

Upon receiving the firing signal, the bullet movement calculating section 122 outputs the changed object information (X0, Y0, Z0, θ0, φ0) of the moving object at the moment when the firing signal is input from the object information storage section 104. , Ρ0).

Next, the bullet movement calculator 122 determines that the firing position is (X0, Y0, Z0) and the firing direction is (θ0, φ0).
Then, the movement position of the bullet whose firing time is the time when the firing signal is input is calculated. In this case, the motion of the bullet obtained by calculating the moving position of the bullet is, for example, a completely linear motion in a direction assuming a future tank game in space. On the other hand, this is a future tank game on the earth or the like, and if gravity is taken into consideration, it will be a parabolic motion. And if the parabolic motion is used, the future tank 20
Can be hit even if the gun barrel is not completely facing the enemy future tank 22. That is, as shown in FIG. 3, the first and second plateaus 76 and 78 are interposed between the future tank 20 and the enemy future tank 22, and even from a position where the enemy cannot be seen from the own aircraft, for example, for a long distance. Cannons can attack enemies. This makes it possible to attack the enemy from a blind spot that is not visible to the enemy due to the three-dimensional terrain, and it is possible to further enhance the fun of the game.

In this future tank game, since the axis of the attack is set so as to substantially coincide with the front direction of the moving object, the object information of the moving object is stored in the initial position of the shooting position and the shooting direction of the bullet. Can be used almost as is for the value.
However, depending on the game, the moving body and the attack direction, that is, the direction of the gun barrel may be set so that they can be individually operated.
In this case, the bullet movement calculation unit 122 determines initial values of the shooting position and shooting direction of the bullet based on the object information of the moving body and the operation signal of the gun barrel.

Next, the movement position of the bullet, for example, the missile's bullet is input from the bullet movement calculation unit 122 to the tracking movement calculation unit 124. The movement position of this missile bullet reflects the terrain information as described above. It is calculated as the moving position of the shot bullet.

The tracking movement calculation unit 124 performs a calculation to change the movement position of the missile bullet based on the object information of the future enemy tank 22 stored in the object information storage unit 104. 22 and 23 show examples of missile tracking movement positions changed by the tracking movement calculation unit 124. FIG. 22 shows a case where a missile is hit by tracking, and FIG. 23 shows a case where a missile was hit but a missile was hit. It is shown when there was no. Hereinafter, the calculation of the tracking movement position will be described with reference to FIGS. For the sake of simplicity, a two-dimensional case will be described here. However, this calculation is actually performed in three dimensions.

Now, the initial position of the missile 98 is set to M0 (X0
, Y0) and the position of the enemy future tank 22 as En (XE
n, YEn). The calculation is performed for each frame (1/6
0 second), and the time of one frame is T.

First, the missile initial position M0 (X0, Y0) and the missile speed V (V
X, VY) are input. As a result, if the change calculation by the tracking movement calculation unit 124 is not performed, the movement position M1 (X1, X1) of the next missile is M1 (X1, X1) = M0 (X0, Y0) + V (VX , VY) .times.T = (X0 + VX.times.T, Y0 + VY.times.T) = (X0 + VX.times.T, Y0 + VY.times.T). Therefore, with such an arithmetic method,
In both cases of FIG. 22 and FIG. 23, the missile will not hit the enemy future tank 22.

On the other hand, the tracking movement calculating section 124
First, the enemy future tank 2 is read from the object information storage unit 104.
The initial position E0 (XE0, YE0) of the second missile is read out, whereby the moving position M1 (X1, Y1) of the next missile is: D0 (DX0, DY0) = E0 (XE0, YE0) -M0 (X0)
, Y0) M1 (X1, Y1) = M (X0, Y0) + V (VX, VY)
It is calculated as × T + K × D0 (DX0, DY0). Therefore, X1 and Y1 are calculated as follows: X1 = X0 + VX.times.T + K.times. (XE0-X0) Y1 = Y0 + VY.times.T + K.times. (YE0-Y0). Here, K is a tracking constant, and the larger this K is, the higher the tracking power of the missile can be.

Similarly, the next missile movement position M
2 (X2, Y2), M3 (X3, Y3), ---, Mn
(Xn, Yn) is calculated as follows. X2 = X1 + VX.times.T + K.times. (XE1-X1) Y2 = Y1 + VY.times.T + K.times. (YE1-Y1) X3 = X2 + VX.times.T + K.times. (XE2-X2) Y3 = Y2 + VY.times.T + K.times. (YE2n) Xn-1 + VX.times.T + K.times. (XE (n-1) -X (n-1)) Yn = Yn-1 + VY.times.T + K.times. (YE (n-1) -Y (n-1)) Tracking movement calculation unit 124
As a result of the change calculation, when the future enemy tank 22 is finally positioned in the traveling direction of the missile 98, the missile 98 hits the future enemy tank 22 as shown in FIG. Conversely, if the enemy future tank 22 is not located in the direction of travel, the missile 9
8 will not hit the enemy future tank 22. Also, as can be seen from the above formula, if the enemy future tank 22 escapes faster than the missile tracking power, the enemy future tank 22 can escape from the missile attack. Therefore, by appropriately selecting the value of the tracking constant K in consideration of the speed of the enemy future tank 22, etc., it is possible to adjust the hit range, thereby adjusting the difficulty of the game. Becomes

Note that the missile tracking change calculation is not limited to the above equation, and various schemes can be used.
For example, using the angle θ between the direction of the missile and the direction of the enemy future tank 22 shown in FIGS. 22 and 23, Xn = Xn−1 + VX × T + K × θXn−1 Yn = Yn−1 + VY × It can also be calculated as T + K × θYn-1.

In the hit judging section 126, the bullet movement calculating section 1
22, the moving position of the bullet changed by the tracking movement calculating unit 124 is set to the enemy future tank 22 or the obstacle 8
It is checked whether there is no terrain information such as 0 or the second and third plateaus 76 by referring to the respective object information in the object information storage unit 104, and a hit determination signal according to the situation is output.

For example, if the enemy future tank 22 is located at the moving position of the bullet, a three-dimensional object indicating that the position of the enemy future tank 22 has been hit, for example, a three-dimensional object of a fire pillar, is formed by the hit determination signal. I do. Specifically, the object information (X, Y, Z) of the fire pillar whose object information (X, Y, Z) is the same as the position of the future enemy tank 22 is newly formed in the object information storage unit 104. At the same time, it calculates the damage given to the enemy future tank 22 by the hit bullet. When it is determined that the enemy future tank 22 has been destroyed by this damage calculation, processing such as erasing the object information of the enemy future tank 22 stored in the object information storage unit 104 is performed. Also, if it is determined that the enemy future tank 22 has been deformed due to the damage of the bullet, but has not been destroyed, the index of the object information representing the enemy future tank 22 is changed to the index of the object information representing the deformed enemy future tank 22. change. Thereby, the deformed enemy future tank can be displayed by the image synthesizing unit 200.

Further, for example, when there is an obstacle 80 at the moving position of the bullet, the object information of the obstacle 80 in the object information storage unit 104 is deleted. Thereby, the obstacle 80 can be destroyed by the bullet.

Further, for example, when there is a terrain such as a second plateau at the moving position of the bullet, the bullet becomes invalid and the object information of the bullet in the object information storage unit 104 is deleted.

After the object information is changed as described above, the image synthesizing section 200 synthesizes a pseudo three-dimensional image according to the changed object information.

FIGS. 24A to 24D show the missile 98.
Shows an example of a pseudo three-dimensional image until the vehicle tracks the enemy future tank 22 and hits it. FIG. 3A shows a state where the future tank 20 has fired a missile 98. As shown in the figure, the future tank 20 of its own is at the position of the slope 75. Therefore, the barrel of the future tank 20 is not directed toward the enemy future tank 22. Therefore, if the missile 98 does not have a tracking system, the future tank 20 of its own cannot hit the enemy with the missile 98. FIGS. 7B and 7C show a state in which the missile 98 tracks the enemy future tank 22 after the launch. At this point, if the enemy future tank 22 escapes and the speed of the escape is high, the missile 98 cannot track and the missile 98 does not hit. FIG. 3D shows a pseudo three-dimensional image when the missile 98 hits the enemy future tank 22 by tracking. In this case, as shown in FIG.
6 instructs the enemy future tank 22 to place a hit mark, that is, a fire pillar 99, at the position of the future tank.

As described above, according to the present embodiment, even in the case where the terrain information is reflected on the movement position of the bullet and the hit determination in the terrain formed in three dimensions, the tracking system is used to prevent the enemy from hitting the enemy. Game settings can be made to make attacks easier. And in this case, because of the speed of the enemy,
By appropriately adjusting the tracking constant K, game settings of various difficulty levels can be set, and a very flexible three-dimensional game device can be realized.

Further, in FIGS. 26A to 26C, the shield amount 44 of the player's own device and the shield amount 45 of the enemy can be viewed at the same time, so that the judgment at the time of offensive and defense can be made immediately. In addition, these displays are concentrated around the periphery of the sight, so that the player can check the information without moving the line of sight from the sight much,
It is understood that this is an excellent aiming system. In this regard,
For example, in the display screen shown in FIG. 20A, the shield display unit 54 is arranged at the left corner of the screen, so that the player can hardly see it during the battle, and the display method of the present embodiment is better. Obviously, this is an excellent display method.

26 (d) and 26 (e), a compass 47 indicating the status of the aircraft in which direction the aircraft is facing north, south, east and west is displayed near the periphery of the sight. I have. Thereby, the player can immediately confirm in which direction of the east, west, north and south the player is moving. That is,
With the enemy position detection radar 50 shown in FIG. 20A, only the relative positional relationship between the own aircraft and the enemy could be grasped. On the other hand, by displaying the compass meter 47, the player can immediately confirm the absolute direction of the player without having to shift his / her eyes.

As described above, according to the present embodiment, it is possible to display various types of self-status information in a concentrated manner in the vicinity of the aim. As described above, the target state information of the enemy can also be displayed on the marker 30 that is always attached to the enemy future tank 22. As a result, with these combinations, the player sets all of the self-state information and the target state information while aiming at the enemy future tank 22 with the aim 40.
Focused viewing can be performed without changing the line of sight. As a result, the aiming system based on these combinations can move freely in the virtual three-dimensional space and attack the enemy.
It is understood that the optimal aiming system is used in a three-dimensional game device.
