DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-player game apparatus, and more particularly to a multi-player game apparatus that sets a handy for each player and thereby sets a battle environment.

[0002]

2. Description of the Related Art Conventionally, a multi-player game apparatus in which a plurality of players compete with each other to play a game is well known. As such a game, for example, a race game in which a plurality of game machines are connected to a communication line and each player competes on a common circuit is known.

[0003] In these multi-player games, in addition to the fun of the game itself, a new element that each player competes with each other's skills is added.
The added value of the game device can be greatly increased. Therefore, for example, even with the same game configuration, the popularity of the game often increases simply by adopting a multi-player type game configuration. As a result, in recent years, development of various multiplayer game devices has been advanced.

[0004]

As described above, in the multi-player game apparatus, the competition between the skills of the players is an important factor that significantly enhances the fun of the game.

[0005] However, if all the wins and losses of the game are determined only by the skill of the player, there may be a case where the interest of the game is reduced by half.
For example, if there is a player with a remarkably high skill, the other players cannot win the player and immediately get bored of the game. On the other hand, even if the player having a high skill level plays the game against such a weak player and wins, the player cannot obtain a satisfactory feeling.

[0006] Further, if, for example, one of the players becomes very disadvantageous with the progress of the game, the game ends immediately unless the other player is rescued at all. I can't increase the fun of the game.

[0007] In other words, in the game, the battle between the players is always directed, and the fun can be maximized only if the players fight each other with the dying power until the end.

[0008] However, the conventional multi-player game apparatus has not sufficiently achieved the technical problem of the essential part of such a game, that is, the part of always producing a friendly match.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and an object of the present invention is to provide a multi-player game device capable of producing a friendly game by controlling a player's battle environment. It is in.

[0010]

According to a first aspect of the present invention, there is provided a display device provided for each player, a game operating device provided for each player, and a game operating device provided for each player. A game calculation means for performing a multi-player game calculation based on the operation signal from and displaying a game screen on the display device, wherein the game calculation means comprises:
A handy setting unit for setting the handy of each player based on the game situation of each player, and a battle for setting the battle environment by setting the battle environment information of each player for each player based on the set handy And an environment setting unit.

The invention of claim 2 is characterized in that the battle environment setting section sets the battle environment information by changing a predetermined reference value based on the handy.

The invention of claim 3 is characterized in that the battle environment setting section sets the battle environment information by selecting a plurality of battle environment information prepared in advance based on the handy.

According to a fourth aspect of the present invention, the game computing means includes a game space computing section formed so that a moving body speed different for each player can be set for a moving body operated by each player. The battle environment information set by the environment setting unit is the moving body speed setting information.

According to a fifth aspect of the present invention, the game operation means includes a game space operation section formed so that different visibility conditions can be set for each player, and battle environment information set by the battle environment setting section. Is setting information of the visibility state.

According to a sixth aspect of the present invention, the game calculation means includes a game space calculation section formed so as to be able to set a different tracking force of a bullet for each player, and a battle set by the battle environment setting section. The environment information is setting information of the tracking power of the bullet.

[0016]

According to the game device of the present invention, a handy is set for each player according to the game situation.

[0017] The battle environment information of each player can be set for each player based on the set handy. Thus, for example, when the battle environment information is the setting information of the speed of the moving object, the speed of the moving object of the player having the poorer game result is increased, and quick attack and defense can be performed.

If the battle environment information is view condition setting information, for example, the view condition of the player with the poorer game performance is improved, and the battle can proceed advantageously.

When the battle environment information is the setting information of the tracking power of a bullet, for example, a bullet fired by a player with a poor game score is likely to hit, and a bullet fired by a player with a good game score is hit. It becomes difficult.

[0020]

【Example】

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

The multiplayer game realized by the present game apparatus 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, each player participates in the game as one of these fighters.

FIG. 2 is an external view of the game apparatus. As shown in the figure, the player 302 operates the left and right analog levers 12 and 14 as operation units to
Is operated, that is, the future tank 20 is operated. That is, the player 302 determines that the future tank 20
, It is possible to freely move forward, backward, left and right in the game field 60 set in the virtual three-dimensional space. Also, this analog lever 1
2 and 14 are equipped with machine guns that can be fired indefinitely and missile triggers 16 and 18 that are a limited but powerful weapon. 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 opponent player who is 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.

The future tank 20 controlled by the player 302 and the future tank 22 for the enemy player controlled by the opponent player
Face each other on this zero zone 66. In FIG. 3, since the second and third plateaus 76 and 78 are interposed between the future tank 20 and the enemy player future tank 22,
The player 302 cannot view the enemy player future tank 22 on the CRT 10. Therefore, the player 302 first finds the enemy position 52 by the enemy position detection radar 50 described above. And analog lever 1
Control the future tank 20 by means of the second plateau 14 and the second plateau 76
, Approaching the enemy and attacking it.

FIG. 4 shows a CR when the own future tank 20 approaches the enemy player future tank 22 in this manner.
A pseudo three-dimensional image projected on T10 is shown.
Here, the shield display unit 54 displays the shield amounts of the own tank and the future tank 22 for the enemy player. Current,
The shield amount (defense power) of the own aircraft greatly exceeds the shield amount of the future tank 22 for the enemy player. Therefore, the marker 30 for marking the future tank 22 for the enemy player is blinking as shown in FIG. In addition, there are enough missiles as shown in the missile remaining amount 43. On the other hand, the enemy player has no remaining missile. Therefore, it is a chance for the player 302 to attack, and conversely, the future tank 22 for the enemy player has to avoid this crisis situation and search for an item that recovers the shield amount.

By the way, in such a player-competitive game, if there is a difference in skill among the players, the poor player is always defeated by the opponent, and it is difficult to win the game, and the unskilled game is played. Can not do.

In particular, in the conventional battle game, the battle environment of the player, for example, the attack capabilities of the future tanks 20 and 22,
Defensive abilities were often set to a common one. Therefore, in the situation shown in FIG. 4, that is, when the other player is overwhelmingly disadvantageous, the other future tank is surely destroyed, and the game is often ended. However, with this, it is not possible to produce a game that is unbeatable,
Soon the player gets bored. Therefore, in such a case, it is desirable to set a battle environment that is disadvantageous for one player and advantageous for the other player. With this setting, the other player can escape from this crisis situation, for example, recovering shield quantity with shield items, refilling missiles with missile items, and retrying in a new place It becomes possible.

As described above, if the setting of the battle environment is changed or selected according to the game situation of the player, for example, the skill of the player, the shield amount of the player, or the like, a more friendly game can be produced. Therefore, a major technical problem is how to reflect the game situation of the player in the setting of the battle environment.

FIG. 5 is an external view of the game apparatus when the game is played by two players. In this case, the player 302 controls the future tank 20 while watching the CRT 10, and the player 303 controls the future tank 22 for the enemy player while watching the CRT 11. Then, a pseudo three-dimensional image viewed from the direction of the future tank 20 is displayed on the CRT 10, and a pseudo three-dimensional image viewed from the direction of the future tank 22 for the enemy player is displayed on the CRT 11. 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. Although FIG. 5 shows only the case of two players, 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. 2. FIG. 1 is a block diagram showing an embodiment of a multi-player game apparatus according to the present invention.

The game device of the embodiment has a structure in which each player 30

The handy setting section 250 controls each player 3 based on the game situation of each player, in particular, the game results.
02 and 303 are calculated and set.

The battle environment setting section 270 changes the battle environment information of each player based on the set handy.
And the battle environment is set accordingly. The battle environment information includes, for example, speed setting information of a moving body controlled by the player, visibility setting information, tracking power of missiles and the like. That is, for example, due to the handy set by the handy setting unit 250, the speed of the moving object of the disadvantaged player is increased, the visibility is improved, and the tracking power of the missile is increased. In addition,
Details of the handy setting unit 250 and the battle environment setting unit 270 will be described later.

When the battle environment is set as described above,
The corresponding pseudo three-dimensional image is generated by the image synthesizing unit 200A,
00B, and the images are output from the CRTs 10 and 11.

FIG. 9 is a block diagram showing an embodiment of the game apparatus in more detail.

As shown in FIG. 9, the game space calculation unit 10
0 is the central processing unit 102, the object information storage unit 10
4. Terrain information storage unit 106, object information change unit 1
08, a marker setting unit 150, an aim setting unit 170, and a handy setting unit 250.

Here, the central processing unit 102 controls the entire game device. Further, a predetermined game program is stored in a storage unit provided in the central processing unit 102. The object information storage unit 104 stores object information as position and direction information of the three-dimensional object forming the virtual three-dimensional space and other attribute information. 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. The object information changing unit 108 performs an operation of changing the object information stored in the object information storage unit 104 at any time based on the terrain information stored in the terrain information storage unit 106. In the marker setting unit 150, setting is performed so that the marker 30 indicating the position of the future enemy player tank 22 as the target is displayed on the pseudo three-dimensional image synthesized by the image synthesis unit 200.
Similarly, the aim setting unit 170 performs setting so that the above-mentioned aim 40 for the enemy player future tank 22 is displayed on the pseudo three-dimensional image.

The handy setting section 250 is configured as shown in FIG. 10, as will be described later, and performs handy setting for each player by comparing the results of each player.

The battle environment setting section 270 includes the central processing section 10
4 and sets the battle environment information, for example, the speed of the moving object, the visibility state, and the tracking power of the missile based on the handy set by the handy setting unit 250, thereby setting the battle environment and setting the battle environment. We are directing games.

Further, in the game device shown in detail in FIG. 9, the image synthesizing section 200 further includes a frame image forming section 18.
0, and the image calculation unit 202 is configured to include an image supply unit 212 and an image formation unit 240.

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

The image supply unit 212 includes a processing unit 214 for controlling the entire image synthesizing unit 200, a coordinate conversion unit 216 for performing three-dimensional arithmetic processing on image information such as vertex coordinates of polygons, and a clipping processing unit 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, the image forming unit 240 further synthesizes the two-dimensional frame image formed by the frame image forming unit 180 with the pseudo three-dimensional image, whereby the marker 30 and the aim 40 are displayed in the pseudo three-dimensional image. The image is output to the CRT 10.

Next, the operation of the whole game apparatus 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 section 104 is stored, for example, in a format shown in FIG. In the figure, the index (0
To n) are serial numbers representing the respective three-dimensional objects. For example, index 0 indicates the future tank 20, index 1 indicates the future tank 22 for the enemy player, index 2 indicates the wall 62, and index 3 indicates the obstacle 80. It is a serial number representing the three-dimensional object to be constituted. Thereby, 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 future tank 22 for the enemy player, the obstacle 80, and the like are set, whereby the positions and directions of all the three-dimensional objects forming the game space on the virtual three-dimensional space are set. The information 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 barrel, and each of these parts is individually divided. 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, for example, as 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 section 150 and the aim setting section 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.

In the handy setting section 250, the game situation,
For example, a handy is set for each player according to the number of wins and losses of each player so far, the shield amount of the future tanks 20 and 22 of each player, and the like. In this case, the winning / losing data of each player and the shield amounts of the future tanks 20 and 22 are as follows.
Results storage memory 2 provided in handy setting section 250
52 and 254. Therefore, the handy setting unit 2
50 stores the data of the number of wins and losses in the results storage memory 25.
2, a predetermined calculation is performed to set a handy.

When a handy is set by the handy setting section 250, the battle environment setting section 270 reads out the handy. Then, the battle environment information is changed and selected based on the handy setting to set the battle environment. For example,
When the battle environment information is the setting information of the speed of the moving body, that is, the future tank, the setting is performed as follows. That is, first, the object information of each of the future tanks 20, 22 is read from the object information storage unit 104. Next, the operation unit 14
First, based on the signals from 0 and 141, the speed of each of the future tanks 20 and 22 as a reference is determined. Thereafter, the speed information of the future tanks 20 and 22 is changed based on the handy. Then, the positions of the future tanks 20 and 22 in the next frame are calculated based on the changed speed information, and the calculated positions are written in the object information storage unit 104. Thus, the battle environment is set based on the handy.

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. In this case, the object information is position information calculated based on a handy according to the game situation as described above.

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, frame data refers to data formed by parameters that change for each frame, and is data common to all three-dimensional objects in one frame, which is the viewpoint position, viewpoint direction, and viewing angle of the player. It consists of data such as information, monitor angle / size information, and 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. As a result, for example, a rearview mirror or
A screen or the like of the future tank 20 viewed from above can be formed.

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 unit 216 reads out the 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 the future tank game as an example, FIG.
, Three-dimensional objects 300 and 33 representing a future tank, a future tank for an enemy player, a building, an obstacle, and the like.
2, 334 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 stored in a viewpoint coordinate system (Xv, Yv, Z) based on the viewpoint of the player 302.
The coordinates are converted to v).

Next, the clipping processing section 218 performs image processing 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 section 222 determines the order of processing in the next image forming section 240, 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 images formed by these image forming units 340 are output from CRTs 10 and 11. As described above, it is possible to form a pseudo three-dimensional image reflecting a handy according to a game situation. 3. Handy Setting Unit Next, the handy setting unit 250 will be described in detail.

FIG. 10 shows an example of the handy setting section 250.

The handy setting section 250 of the embodiment comprises a player score storage memory 252, 254 and a score comparison circuit 2
56, a handy operation circuit 258, and handy storage memories 260 and 262 for each player.

Each player's score memory 252, 25
In 4, the results of the corresponding players 302 and 303 are sequentially written. The score includes the remaining shield amount reduced by the enemy attack, the number of wins from the start of the game to the present, and the like.

The score comparison circuit 256 compares the scores of the players stored in the score storage memories 252 and 254, and outputs the comparison result to the handy operation circuit 258. For example, this comparison operation is performed by obtaining the difference between the remaining shield amount and the difference between the number of wins of each player.

The handy operation circuit 258 calculates the handy data from the comparison result obtained by the comparison circuit 256 based on a predetermined operation expression.
By changing the coefficients and the like of the arithmetic expression, it is possible to change the reflection of the handy in the game in various ways. For example, in the case of a game in which it is not desired to provide a handy or a player who does not want to know the existence of a handy, the coefficient of this arithmetic expression is changed so that the handy value does not increase even in the same game situation. Also, for example,
If emphasis is placed on the shield remaining amount rather than the number of wins, the coefficient of the arithmetic expression is changed in such a manner. In this way, by changing the coefficients of the arithmetic expression or the arithmetic expression itself, it is possible to set various kinds of handy. As a result, even if the games have the same configuration, various game spaces can be formed by changing the settings of the coefficients and the expressions.

The handy data calculated by the handy calculation circuit 258 is stored in the handy storage memory 26 for each player.
0,262. Therefore, the handy data written here is appropriately changed as the game progresses, and the handy data according to the game result is set.

The battle environment setting section 270 reads out the handy of each player stored in the handy storage memories 260 and 262 at various stages during the game, thereby calculating and setting the battle environment information for each player. Will be done.

Next, the calculation performed by the handy setting section 250 will be specifically described.

Assuming that players A and B are to compete with each other, first, the score comparison circuit 256 calculates the difference S in the remaining seal amount from the remaining shield amount s of each player as follows. Is done.

S = s (enemy) −s (self) Therefore, in the case of player A, SA = sB−sA In the case of player B, SB = sA−sB.

The difference W between the number of wins is calculated as follows.

W = w (enemy) −w (self) Therefore, in the case of player A, WA = wB−wA In the case of player B, WB = wA−wB.

Next, the handy operation circuit 258 calculates the handy data. In this case, the handy operation circuit 2
In 58, the following arithmetic expression using S and W as variables is set in advance.

F = F (S, W) Accordingly, the handy data of player A is calculated as follows: FA = F (SA, WA) The handy data of player B is calculated as FB = F (SB, WB)

The result of this calculation is stored in the storage memories 260 and 262 as a handy for each player. 4. Setting of battle environment Although a great many items are considered as the battle environment information set by the battle environment setting section 270, representative ones among them will be described below. (1) Speed of moving object One of the battle environment information is the speed of the moving object controlled by each player. That is, in such a battle game, the speed of the future tank controlled by each player has a great influence on the outcome of the game. Therefore, battle environment setting section 2
70 is formed so that the setting of the speed of this future tank can be changed. Hereinafter, this will be specifically described with reference to FIG.

The coordinate position of the future tank 20 is calculated as follows. That is, first, the object information (X0, Y0) of the future tank is stored from the object information storage unit 104.
, X0, .theta.0, .phi.0, .rho.0). In addition,
Hereinafter, in order to simplify the description, Z coordinate and direction information θ,
φ and ρ are not considered.

In this state, it is assumed that the player 302 (hereinafter, referred to as player A) operates the analog levers 12 and 14 connected to the operation unit 140 to input operation signals. For example, assume that the player 302 has tilted the analog levers 12 and 14 forward, and the future tank has advanced forward. Then, speed information (VXA0, VYA0) is input from the operation units 140 and 141 in accordance with the operation amount. Then, the position coordinates (XA1, YA1) one frame later, that is, (1/60) seconds (hereinafter, referred to as T seconds) are calculated as follows.

(XA1, YA1) = (XA0 + VXA0 × T, Y
A0 + VYA0 × T) Similarly, player 303 (hereinafter referred to as player B)
Are the analog levers 32 and 34 of the operation unit 141 shown in FIG.
By operating the speed information (VXB0, VYB0)
Is input, the position table after one frame (XB1, YB
1) is calculated as follows.

(XB1, YB1) = (XB0 + VXB0 × T, Y
(B0 + VYB0 × T) Accordingly, the position information of each future tank after one frame is obtained from the above speed information (VXA0, VYA0), (VXB0, VXB0).
It is understood that YB0) is greatly affected.

Therefore, the battle environment setting section 270 of this embodiment
Is speed information (VXA0, VYA0), (VXB0, VYB0)
Is changed as the battle environment information based on the handy data FA and FB set by the handy setting unit 250. Specifically, a predetermined arithmetic expression GV
(F, VX, VY) are changed as follows. That is, the speed information of the player A is VA0 → GV (FA, VXA0, VYA0), and the speed information of the player B is VB0 → GV (FB, VXB0, VYB0). The information will also be different.

By the above calculation, the player who loses in the number of wins or losses in the game or the player who has a small shield amount has the speed information as the battle environment information set advantageously.
As a result, the future tank also moves quickly, for example, and can easily escape from the enemy's attack, and it is possible to produce an unbeatable game.

Incidentally, the above description is made for simplicity of explanation (Z,
Although description of (φ, θ, ρ) is omitted, the same effect can be naturally obtained by changing the speed information in these directions. For example, by changing the speed information in the Z direction, a fighter game, a helicopter
Handy can be set for the climb speed in the game. Similarly, by changing the speed information in the φ, θ, and ρ directions, a handy can be set at a speed such as rotation or turning. (2) Visibility In the present game device, as shown in FIGS. 12A and 12B, fog 24 is virtually generated on the game field, thereby changing the visibility of each player. Can be. For example, FIG. 12A shows a scene where the field of view of the own device is blocked by fog 24. FIG. 2B shows a scene in which the future tank 22 for the enemy player comes out of the fog 24. In this way, the present game device can perform a game effect in which the field of view is blocked by darkness, snow, rain, or the like at night. Therefore, by setting a handy for each player with respect to this visibility state, it is possible to achieve a game effect between the players.

FIG. 11 is a block diagram of an embodiment in the case where fog, darkness at night, and the like are represented on the virtual three-dimensional space. Hereinafter, this will be briefly described first.

The embodiment shown in FIG. 11 is different from the embodiment shown in FIG. 9 in that a view 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.

[0093] Each time the game is started, the visibility condition setting section 190 sets the visibility condition of the game field where the game is played. 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. 13, 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 pallet 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 a case where the fog visibility is set.

In order to represent the visibility of the fog, the color data of each polygon should 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). Accordingly, 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. 13, 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 to use in accordance with the distance, that is, which color palette to use 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 visibility condition setting section 190, the pallet number changing section 19 is set in accordance with the selected face of the player.
2. The visibility of the color code changing unit 194 is set. Specifically, in the case of fog, the code of the color palette at the farthest position is, for example, (100, 100, 1).
00), and at night, for example, (0, 0, 0). Also, if it is sunset (200, 50, 30)
As a little reddish. As for the sea, the deep sea is (0, 0, 50) and the blue is close to black, and the shallow sea is (50, 50, 200) and the blue is strong. For example, if the place where the future tank game is played is a green planet, a little green is added to the fog element, and if it is a sandstorm, a little yellow is added.

As described above, according to the embodiment shown in FIG. 11, it is possible to set various visibility conditions.

In this embodiment, the handy setting unit 25
Based on the handy data set at 0, the battle environment setting unit 270 sets the view condition, which is this battle environment information. However, in the present embodiment, unlike the setting of the speed information described above, the setting of the battle environment information is performed by selecting the battle environment information corresponding to the handy data from a plurality of battle environment information prepared in advance. Have done this. That is, the above-described setting of the speed information is performed by changing the reference value of the speed information set according to the operation signal of the analog lever of the player based on the handy data. On the other hand, in the present embodiment, as specifically described below, this setting is performed by selection from previously prepared battle environment information.

In the present embodiment, the setting of the field of view can be performed for each player based on the handyness by using two methods.

First, one method is to change the selection of a palette number for a polygon for each player based on a handy, which is performed in a palette number changing unit 192. That is, for example, it is assumed that the number of wins of the player A is larger than that of the player B and the remaining shield amount is also larger than the player B. In this case, the handy is set so that the player B is more advantageous. Then, when the handy data is input to the battle environment setting section 270, the battle environment setting section 270 outputs setting information to the visibility situation setting section 190 so that the player B becomes more advantageous in accordance with the handy. . The visibility condition setting unit 190 makes the following settings based on the setting information. That is, when forming a pseudo three-dimensional image viewed from the player A, the palette number changing unit 192 sets the selection of the palette number for each polygon from among the palettes (2 to 8). Conversely, when synthesizing a pseudo three-dimensional image viewed from the player B, it is set so that the selection of the palette number is performed from among the palettes (0 to 6). As a result, it is possible to set such that polygons at the same distance from the respective players are not visible to the player A but are visible to the player B. Thus, the player B can attack from a place where the player A cannot see, and can easily escape from the attack of the player A. Therefore, by making such settings, the battle environment of player B can be made very advantageous. As a result, it is possible to reflect the handy in the battle environment information very effectively.

Another method of reflecting the handyness in the field of view is performed by the color code changing unit 194. That is, first, the color pallets are set for the player A and the player B.
For each player, and are set so that they can be selected from different color palettes when forming a pseudo three-dimensional image of each player. Then, the color code changing unit 194 sets the color code of the color palette for the player A so that the visibility situation deteriorates as soon as the distance increases. Specifically, in FIG.
(170, 65, 30) to (100, 100, 10
The rate of change up to 0) is increased. Conversely, the setting of the color code of the color palette for the player B is set so that the rate of change is reduced. This makes it possible to set the handy field of view more finely than in the above method. (3) Tracking Power In this embodiment, a missile is provided with a tracking function in order to facilitate an attack in a game expressed in three-dimensional terrain and to make the game more interesting. For this reason, by reflecting the handyness on the tracking ability of the missile in this tracking function, it is possible to produce a game that is unbeatable. Hereinafter, the tracking function of the missile will be briefly described with reference to the embodiment shown in FIG.

In the embodiment shown in FIG. 14, 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 judgment by the hit judgment 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 is configured 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 has been set up to solve this problem.

FIG. 14 is a block diagram showing an embodiment in which a tracking system is provided for a bullet. FIG.
The embodiment shown in FIG. 9 is different from the embodiment shown in FIG. 9 in that a trigger determining unit 142 and a bullet processing unit 120 are newly added.

The trigger determining 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. In the tracking movement calculation unit 124,
An operation for changing the movement position of the bullet so as to track the target is performed.

In the hit judging section 126, the target, for example, the future tank 2 for the enemy player
The object information of No. 2 is read, and a hit determination of the bullet is performed based on the object information and the moving position of the bullet changed by the tracking movement calculating unit 124. When a bullet is hit, the hit determination information is stored in the object information storage unit 10.
4 is reflected on the object information of various three-dimensional objects stored in the storage unit 4.

Next, the operation of this embodiment will be described.

First, the object information changing unit 108 performs a change calculation of the object information of the moving body, 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 when it is determined that the trigger has been performed, a firing signal of the machine gun or the missile is formed. It is output to the movement calculation 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 calculation unit 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 future tank game, since the axis of 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 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 topographical information as described above. It is calculated as the moving position of the shot bullet.

The tracking movement calculation unit 124 performs a calculation for changing the movement position of the missile bullet based on the object information of the future tank 22 for the enemy player stored in the object information storage unit 104. 15 and 16 show examples of missile tracking movement positions changed by the tracking movement calculation unit 124. FIG. 15 shows a case where the missile hits due to tracking, and FIG. 16 shows a case where the missile was tracked but the missile hits. It is shown about the case that did not do. Hereinafter, FIG.
The calculation of the tracking movement position will be described based on FIG. 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), the position of the future tank 22 for the enemy player is set to En (XEn, YEn). The calculation is performed for each frame (1/60 second), and the time of one frame is T.

First, the missile initial position M0 (X0, Y0) and the missile velocity 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. 15 and FIG. 16, the missile will not hit the future tank 22 for the enemy player.

On the other hand, the tracking movement calculating section 124
First, the initial position E0 (XE0, YE0) of the future tank 22 for the enemy player is read from the object information storage unit 104, and thereby, the moving position M1 (X1,
Y1) is given by: D0 (DX0, DY0) = E0 (XE0, YE0) -M0 (X0, Y0) M1 (X1, Y1) = M (X0, Y0) + V (VX, VY) × 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 * T + K * (XE1-X1) Y2 = Y1 + VY * T + K * (YE1-Y1) X3 = X2 + VX * T + K * (XE2-X2) Y3 = Y2 + VY * T + Y * Y (T + Y * T2) Xn = 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)) In this manner, the movement position of the bullet is determined by the tracking movement calculation unit 124.
As a result of the change calculation, when the future tank 22 for the enemy player is finally positioned in the traveling direction of the missile 98, the missile 98 is moved to the future tank 22 for the enemy player as shown in FIG.
Hits. Conversely, if the future tank 22 for the enemy player is not located in the traveling direction, the missile 98 will not hit the future tank 22 for the enemy player. Also, as can be seen from the above formula, if the enemy player's future tank 22 escapes faster than the missile's tracking power, the enemy player's future tank 22
Can escape missile attacks. Therefore, by appropriately selecting the value of the tracking constant K in consideration of the speed of the future tank 22 for the enemy player, it is possible to adjust the hit range, thereby adjusting the difficulty of the game. Becomes possible.

Note that the missile tracking change calculation is not limited to the above formula, but various types can be used.
For example, using the angle θ between the direction of the missile and the direction of the future tank 22 for the enemy player shown in FIGS. 15 and 16, Xn = Xn−1 + VX × T + K × θXn−1 Yn = Yn−1 + VY × T + K × θYn-1 can also be calculated.

In the hit judging section 126, the bullet movement calculating section 12
2 and whether there is no terrain information such as the future tank 22 for the enemy player, the obstacle 80, or the second or third plateau 76 at the movement position of the bullet changed by the tracking movement calculation unit 124. Is checked with reference to each object information in the object information storage unit 104, and a hit determination signal according to the situation is output.

For example, when the future tank 22 for the enemy player is located at the moving position of the bullet, a three-dimensional object representing that the position of the future tank 22 for the enemy player has been hit, for example, the fire column 3 Form a dimensional object. Specifically, the object information storage unit 10
In 4, the object information (X, Y, Z) of the fire column whose object information (X, Y, Z) is the same as the position of the future tank 22 for the enemy player is newly formed. At the same time, it calculates the damage given to the future tank 22 for the enemy player by the hit bullet. When it is determined that the enemy player's future tank 22 has been destroyed by this damage calculation,
Processing such as erasing the object information of the enemy player future tank 22 stored in the object information storage unit 104 is performed. If it is determined that the future tank 22 for the enemy player is deformed due to the damage of the bullet, but not destroyed, the future tank for the enemy player for which the index of the object information representing the future tank 22 for the enemy player is deformed is replaced with the future tank for the enemy player. Change to the index of the object information to be represented. As a result, the deformed future tank for the enemy player can be displayed by the image synthesizing unit 200.

Further, for example, when the obstacle 80 is located 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. 17A to 17D show the missile 98.
Shows an example of a pseudo three-dimensional image until the player tracks the enemy player's 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 on a slope 75
You are in the position. Therefore, the barrel of the future tank 20 is not oriented toward the future tank 22 for the enemy player. 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 future tank 22 for the enemy player after the launch. At this point, if the future tank 22 for the enemy player escapes and the escape speed 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 future tank 22 for the enemy player by tracking. In this case, as shown in FIG.
Marks the position of the future tank 22 for the enemy player,
That is, it is instructed to put out the fire pillar 99.

As described above, according to the present embodiment, even when the terrain information is reflected on the movement position of the bullet and the hit determination on the terrain formed in three dimensions, the tracking system is used for the enemy. Game settings can be made to make attacks easier. In this case, by appropriately adjusting the tracking constant K in relation to the speed of the enemy and the like, it is possible to set a game with various difficulty levels, and to realize a highly flexible game device. Become.

In a game device having a weapon having a tracking function as described above, by setting the tracking power, which is this battle environment, based on the set handy, a very unbeatable game can be produced. .

In the present embodiment, the value of the tracking constant K, which is the battle environment information of the tracking power, is set based on the handy. That is, the battle environment setting unit 270 changes the values based on the handy data FA and FB set by the handy setting unit 250 using the tracking constants K0A and K0B of the missiles fired by the players A and B as the battle environment information. are doing. Specifically, it is changed as follows by a predetermined arithmetic expression GK (F, K). That is, the changed tracking constant KA of the missile fired by the player A is KA = GK (FA, K0A), and the changed tracking constant KB of the missile fired by the player B is KB = GK (FB, KB0). .

For example, the player A is now the player B
Suppose you have more wins and more shields remaining. In this case, the handy is set so that the player B is more advantageous. When the calculation shown in the above equation is performed using the handy FA and FB, the tracking constant KB of the player B is set to be larger than the tracking constant KA of the player A. As a result, even if the missile is fired under the same situation, the missile of the player B has a higher tracking power, and therefore, the possibility of being hit is higher. Conversely, by reducing the tracking power of the missile of the player A, the player B can easily escape from the attack of the player A. Therefore, for example, in FIG.
Also, the player B can escape from the missile of the player A. In this case, as described above, the player B
If the setting of the speed information of the moving body is set to be more advantageous due to the handy, the player B can more easily escape from the attack of the player A. As a result, it is possible to produce a more unbeatable game. (4) Others The battle environment information that can be set for each player based on the handyness according to the present invention is not limited to the above, and any information that affects the battle environment can be used. Examples include the range of an attack, the interval between firings of an attack, the speed at which a bullet advances, the speed at which an attack propagates, the range at which the bullet hits, the amount of damage to the opponent when the attack hits, the range of hitting the aircraft, items Various things such as the duration of the effect can be used.

Further, for example, handyness can be reflected in an aiming system for an attack by a bullet. For example, in the game device of the present embodiment, as shown in FIG.
The marker 30 is always stuck to the enemy, and the status information of the enemy aircraft can also be visually displayed. For example, as shown in FIG.
As shown in (B) and FIGS. 18 (A) and (B), the marker 30 of the game device is obstructed by the fog 24 and the obstacle 82 so that the future tank 22 for the enemy player is not visible. It is stuck at the position corresponding to the position of the enemy. Therefore, for the winning player, a setting is made such that the marker 30 is not shown at all, or an obstacle 82,
If you set it not to show when it is blocked by fog 24,
Handy will be reflected in the battle environment. (5) Multiplayer Game FIG. 19 shows an example of a multiplayer game device according to the present invention.

As shown in the figure, in the case of this example, the operation units 140 and 141 having the same configuration and the game space operation unit 10
0, object information storage unit 104, image synthesis unit 20
0, two or more CRTs 110 and 111 are prepared. Then, as shown in the figure, the object information stored in the object information storage unit 104, the handy calculated by the handy setting unit 250, and the battle environment setting unit 270
The battle environment information calculated by the above is shared, thereby providing a multi-player game device. The common method may be communication or the like, or may be a method of sharing a substrate or the like.

It should be noted that there are various other configurations for the multiplayer game. For example, a setting is made so that a plurality of data groups composed of the frame data shown in FIG. In this way, different viewpoint positions and viewpoint directions can be set by the respective frame data of the plurality of data groups. With this setting, one game space calculation unit 100 and one image synthesis unit 20 can be set within the allowable range in terms of hardware speed.
By 0, a plurality of pseudo three-dimensional images with different viewpoint positions and viewpoint directions can be formed. By displaying the pseudo three-dimensional images viewed from different viewpoint positions and viewpoint directions on the CRTs 110 and 111 of the respective players,
As shown in FIG. 19, a multi-player game device can be realized without providing a plurality of image synthesizing units and a game space calculating unit.

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

For example, the game device according to the present invention can be applied to devices having various hardware configurations. That is, the present invention can be applied to, for example, a game device for business use, a game device for attractions as described above, and a driving simulation for a driving school. Further, the present invention can be applied to, for example, a home game device having a configuration as shown in FIG.

This home game apparatus comprises a game cartridge 401 and a game machine main body 400, and is connected by a connector 498. Game cartridge 40
1 includes an auxiliary arithmetic processing unit 410, a first storage unit 480, and a second storage unit 490. First storage unit 4
Reference numeral 80 denotes a non-volatile memory, for example, and includes an object information storage unit 104 and a three-dimensional image information storage unit 204. The auxiliary processing operation unit 410 includes an image supply unit 212, an image forming unit 240, and a handy setting unit 25.
0, a battle environment setting unit 270, and a control unit 214. Further, the second storage unit 490 is configured by a rewritable memory.

This home-use game machine operates almost in the same way as the embodiment shown in FIG. That is, the first storage unit 48
Using the object information stored in “0” and the operation signal from the operation unit 408, the central processing unit 102 and the auxiliary calculation processing unit 410 set a game space, that is, set object information. Next, using the object information and the three-dimensional image information stored in the first storage unit 480, a pseudo three-dimensional image is calculated by the auxiliary processing calculation unit 410 and the central processing unit 102. It is stored in the second storage unit 490. After that, the stored image information is stored in the video processing unit 404 and, if necessary, the video RAM.
Video is output via 406.

The handy setting section 250 and the battle environment setting section 270 can reflect the handy in the battle environment as in the embodiments described above.
