Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a competitive game device in which a competitive game image is displayed on a display.

[0002]

2. Description of the Related Art Conventionally, various shooting devices have been known, for example, a game in which a moving body operated by a player and a moving body of an enemy freely move around in a virtual three-dimensional game space while fighting. There is something to do.
In this game device, an image of the scenery in the three-dimensional game space viewed from the player's viewpoint (the viewpoint of the player on the moving body) is displayed on the display, and an attack item, for example, a sight for a missile, is displayed in the center of the screen. Is displayed.
The player operates his or her own moving body so that the moving body of the enemy is within or near this aim, and operates the trigger button to launch the missile and destroy the enemy moving body. Similarly, the enemy moving body also attacks the player moving body using a missile or the like.

A predetermined initial shield amount is given to each moving body in advance, and for example, each time the opponent's missile hits (hits) its own aircraft, the amount of damage caused by the missile is sequentially subtracted from the shield amount. Is displayed on the display as the shield remaining amount. When the remaining shield amount becomes 0, the moving body explodes, and the winning or losing of the game is decided.

Therefore, the player sees the remaining amount display of the missile (the remaining amount display of the missile currently held by the player moving body) displayed on the display during the game, and the combat ability of the moving body of the player itself. If you find out that the missiles are running low, or if you have missed out on the missiles, you must stop the battle with the enemy and escape from the enemy in battle to replenish the missiles.

[0005]

However, in the conventional game device, when the missile attack from the opponent is hit,
It was configured to always subtract a certain amount of damage from the remaining shield amount.

Therefore, for example, when shooting a missile during battle and escaping from the enemy to replenish the missile, the remaining amount of the shield becomes 0 due to the missile attack of the enemy, and the enemy often destroys it. was there.

[0007] In particular, the psychology of the player is that he can endure even if he is defeated by an enemy in battle, but if he is destroyed when he escapes from an enemy in battle, the excitement of the game cools down and he has the desire to try the game again. Often decreases.

Particularly, in the case of a game device for business use, ending the game with excitement for the game motivates the player to challenge the next game, and raises the operating rate of the game device itself. Is important, and measures for it are required.

The present invention has been made in view of such conventional problems, and an object of the present invention is to detect an enemy item based on the remaining amount of an attack item of a player moving body, for example, an attack item such as a missile. A battle-type game in which the amount of damage caused by an attack can be changed to create a more interesting game by directing the game so that it will not be easily attacked by the enemy when escaping from an enemy in battle to replenish the attack items. To provide a device.

[0010]

In order to achieve the above object, the invention of claim 1 is a display, a game operating means operated by a player, an input signal from the operating means, and a predetermined game program. Based on the above, a game calculation means for performing a calculation of a battle-type shooting game in which a player or a moving body operated by the player moves and fights an enemy by using an attack item, and displaying a game screen on the display, The game calculation means includes an item remaining amount calculation means for detecting the remaining amount of the attacking item of the player or the player moving body, and whether or not the attack by the attack item from the enemy against the player or the player moving body is effective. Attack determination means to be used, and each time an enemy attack is determined to be valid Damage amount accumulating means for accumulating the amount, the damage amount accumulating means changing the amount of damage caused by the attack of the enemy attack item based on the remaining amount of the attack item possessed by the player or the player moving body. Characterize.

Here, the damage amount integrating means is
It is preferable that the amount of damage caused by the attack of the enemy attack item is set to be small as the remaining amount of the attack item of the player or the player moving body decreases.

With such a configuration, when the remaining amount of the attacking item becomes small during the battle with the enemy, the battle with the enemy is temporarily interrupted, and the item is replenished, The probability that the player or the player moving body is destroyed can be reduced. As a result, the probability that the battle with the enemy will be settled during the battle with each other is high, and the player can finish the game while fully enjoying the fun and power of the battle-type game, and a more powerful and interesting battle. It is possible to realize a game device capable of playing a type game.

Further, in the invention of claim 3 according to any one of claims 1 and 2, the damage amount integrating means is an enemy attack item as the remaining amount of the attack item held by the player or the player moving body decreases. Damage amount calculation means for setting the amount of damage caused by the attack of a small amount, and a predetermined initial shield amount is set in advance, and each time it is judged that the attack from the enemy is effective, the amount of damage caused by the enemy attack item from the initial shield amount A shield amount updating means for subtracting the amount and outputting the shield remaining amount, and a value obtained by subtracting the integrated value of the amount of damage caused by an enemy attack item from the initial shield amount is displayed on the display as the shield remaining amount. It is characterized by doing.

That is, in the battle-type game device, a predetermined initial shield amount is set in advance for the player or the player moving body, and each time it is judged that the attack from the enemy is effective,
In many cases, the game is set so that the amount of damage caused by an enemy attack item is sequentially subtracted from the shield amount, and the player or the player moving body is destroyed when the shield remaining amount becomes zero.

According to the present invention, in such a game device, when the remaining amount of the attacking item becomes small during the battle with the enemy and the player escapes from the enemy to supplement the item,
Since the amount of damage done by the attack of the enemy attack item is small, the probability of being destroyed by the enemy at this time can be reduced.

Further, in the invention of claim 4, in claim 3, the game calculation means includes an item generation means for generating a damage recovery item in the game space, and the damage recovery item acquired by the player or the player moving body. It is characterized by recovering the remaining amount of shield based on.

As described above, by adopting the structure in which the shield remaining amount is recovered by acquiring the damage recovery item, the player can assemble a variety of game strategies and enjoy the game.

Further, the invention of claim 5 is characterized in that, in any one of claims 3 and 4, the game calculation means is formed so as to calculate a shield remaining amount of a player or a player moving body and an enemy. To do.

As a result, a more interesting game can be realized.

31 missile display symbols 31-1, 31-2, ... 31
-6 is arranged in a ring shape. When one missile is shot, the corresponding symbol disappears, and the missile remaining amount is displayed according to the number of remaining symbols.

The player searches for a missile item 84 that appropriately occurs in the game space, and by colliding the player's future tank 20 of his own machine, the missile is fully equipped, that is, the missile is equipped with six missiles. The remaining amount can be recovered. In addition, missile item 84
Depending on the situation, the recovery may be performed by a predetermined number.

Of course, the future tank 20 operated by the player is also attacked by the enemy future tank 22 using missiles and machine guns in the same manner. Therefore, the player avoids the attack from the opponent and the future tank 20
It is necessary to attack the enemy future tank 22 while driving.

Further, on the display 110, the radar 24 for displaying the tank position of the target enemy and the shield display portions 26a, 26b for displaying the shield amounts of the own aircraft and the enemy.
And are displayed.

The radar 24 has a player future tank 2
The position of 0 is displayed as a large point 24a in the center, and the position of the enemy future tank 22 is displayed as a small point 24b.
This allows the player to know the position of the enemy future tank 22 even if it is not displayed on the display 110.

The shield amounts of the future tanks 20 and 22 displayed on the shield display portions 26a and 26b are sequentially subtracted by the damage amount each time the opponent's attack is damaged, and the shield remaining amount is reduced. The game is set so that the future tank is destroyed when the amount value becomes 0. Then, it is set that the player who defeats the opponent's future tank three times in advance becomes the winner of the game.

Since a shield item 86 is appropriately generated in the game space, the player finds this shield item 86 and crushes the player's future tank 20 to recover the remaining shield amount to the initial state. You can Depending on the shield item 86, the predetermined amount may be recovered.

An overall view of the game field 60 is shown in FIG.

In the game field 60, various three-dimensional topography set by the game program is formed. 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 inside the wall 62. The zero-meter zone 66 is surrounded by this first plateau 64, with slopes 68, 70, 7 between them.

By operating the levers 12 and 14, the player P moves his or her future tank 2 to a position where the enemy future tank 22 can be easily attacked within the game field 60.
Move 0 freely to make that attack.

In the play field 60,
As the game progresses, supplementary missile items 84 and shield items 86 for recovering the shield amount shown in FIGS. 3B and 3C are set. This item 84,86
Is obtained by crushing the own future tank 20.

FIG. 4 shows a block diagram of the game apparatus 10 of the embodiment for playing such a three-dimensional game.
Note that description of the configuration for transmitting and receiving data to and from other game devices is omitted.

The game device 10 of the embodiment has an operation unit 100.
And a game calculation unit 102 and the display 110.

The operating section 100 is a member operated by the player, such as the levers 12 and 14 and the triggers 16 and 18 shown in FIG.

The game calculation section 102 includes a game space calculation section 120 and an image composition section 140.

The game space calculation unit 120 performs various game calculations based on an input signal from the player operation unit 100 and a predetermined game program, and uses the image synthesizing unit 140 to display the above on the display 110. A pseudo three-dimensional game image of the future tank game is displayed.

That is, the game space calculation unit 120
Performs a game calculation in which the future tanks 20 and 22 operated by the player P and the computer move in the game field 60 set in a predetermined three-dimensional game space as shown in FIG.

Then, the image synthesizing unit 140 performs perspective projection conversion of this three-dimensional game space onto a perspective projection plane of a predetermined viewpoint coordinate system to form a game screen made up of pseudo three-dimensional images, which is displayed on the display 110. Display on top.

FIG. 5 shows the principle of such an image synthesizing method.

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

Taking the future tank game of the embodiment as an example, 3
The three-dimensional object 510 is the future tanks 20 and 22 appearing in the three-dimensional game space 500. In addition to this, various three-dimensional objects representing the game field 60 shown in FIG. Are arranged.

These three-dimensional objects are perspective-projected on the perspective projection plane 520 of the viewpoint coordinate system centering on the viewpoint 610 of the virtual player P, and the pseudo three-dimensional image 522 is obtained.
Is displayed on the display 110. In the embodiment, the viewpoint 610 of the player P is set from the rear of the future tank 20 operated by the player toward the front including the future tank 20 operated by the player. Therefore, as shown in FIG. 6, the three-dimensional game space 5 is displayed on the display 110.
A view of 00 from the rear of the future tank 200 is displayed as a pseudo three-dimensional image.

The player P uses the lever 1 of the operation unit 100.
When the virtual tank 20 in which the user is virtually operating is rotated or translated by operating 2 or 14, the position of the viewpoint 610 with respect to the three-dimensional game space 500 changes, and the three-dimensional game space 500 Will be rotated and translated. Therefore, the game space calculation unit 120 calculates in real time the rotation and translation of the three-dimensional object 510, which is a future tank configuring the three-dimensional game space 500, and other three-dimensional objects based on the operation signal and the game program. Done in. And, as mentioned above, these 3
The three-dimensional object is perspective-projected on the perspective projection plane 520 and is displayed on the display 110 as a pseudo three-dimensional image 522 that changes in real time.

Therefore, the player P operates the operation unit 100 to operate the future tank 20 to drive the future tank 20 in the game field 60 set in the three-dimensional game space 500 while playing the game. You will be able to virtually simulate your participation.

When the computer graphics method is used, the shape model of the three-dimensional object 510 is created using an independent body coordinate system.
That is, the polygons 512-1, 512-2, ... Forming the three-dimensional object 510 are arranged in this body coordinate system to specify the shape model thereof. Moreover, three-dimensional game space 500, the world coordinate system _{(X W, Y W, Z} W) is constructed using a three-dimensional object 510 represented using a body coordinate system, the world coordinate system according to the motion model Placed inside.

Then, with the position of the viewpoint 610 as the origin,
The data is converted into a viewpoint coordinate system in which the direction of the viewpoint is the positive direction of the Z axis, and the respective coordinates are perspective-projected converted into the screen coordinate system which is the projection surface 520. In this way, the image within the field of view of the three-dimensional game space 500 that can be seen from the viewpoint 610 can be displayed on the display 110.

Then, the player P plays the display 110.
While watching such a game screen displayed above, it is possible to enjoy a three-dimensional game in which the enemy future tank 22 is attacked.

By the way, when fighting with the enemy's future tank while looking at the game screen displayed on the display 110, it is possible to effectively utilize the offensive items such as missiles that cause great damage to the opponent. It becomes important.

When all the missiles of the player's future tank 20 are exhausted before the opponent is defeated in the battle, or when the number of missiles remaining becomes small, the missile item escapes from the enemy in the battle. I need to find 84 and refill my missiles.

However, if the player's future tank 20 is destroyed by the missile attack of the enemy future tank 22 on the way to escape from the enemy to replenish the missile, the game is over without the game being excited, which is preferable. I mentioned earlier that there is nothing. The feature of the present embodiment is that the amount of damage to the enemy future tank 22 due to the missile attack is set to be small as the remaining amount of missile items of the future tank 20 operated by the player decreases. This reduces the probability that the player's future tank 20 will be destroyed when escaping from the enemy future tank 20 to replenish the missiles, and the final game between the player and the enemy will be settled when they are fighting each other. The probability of doing so is high. Therefore, when the player is excited by the battle with the enemy,
The game can be over, and the player can be motivated to try the game again.

Therefore, the game space calculation unit 12 of the embodiment
0 is the shield remaining amount calculation unit 122, the hit check unit 1
24, item generation unit 126, item acquisition determination unit 12
8 is included.

FIG. 7 shows a specific functional block diagram thereof.

The hit check section 124 functions as an attack determination means, and the player future tank 20 by a missile from the enemy future tank 22 or a machine gun.
It is determined whether or not the attack on the enemy future tank 20 using the missile by the player future tank 20 or the machine gun is effective, and the determination result is sent to the shield remaining amount calculation unit 122. Is configured to output to.

The item generation unit 126 is configured to generate a missile item 84 and a shield item 86 at an arbitrary position in the game field 60 shown in FIG. 3 as the game progresses. The position data is output to the item acquisition determination unit 128.

The item acquisition determination unit 128 determines the future tanks 20 and 22 based on the traveling position data of each future tank 20 and 22 calculated by the game space calculation unit 120 and the input data from the item generation unit 126. It is determined whether or not the missile item 84 and the shield item 86 are acquired, and the determination result is held by the missile counter unit 130.
Is output to the shield remaining amount calculation unit 122.

The possessed missile counter section 130 is
It functions as an item remaining amount calculating means for counting the number of missiles possessed by each future tank 20, 22. In the embodiment, at the start of the game, the number of missiles held by the future tank 22 is set to N = 6, and the number of missiles held by the enemy future tank is set to N = 4. Then, each time a missile trigger for instructing the missiles of the future tanks 20 and 22 is input, the number of missiles of the relevant future tanks 20 and 22 is subtracted by one, and this is used as the remaining missile shield. Output to the remaining amount calculation unit 122. Also, the item acquisition determination unit 12
When a missile item acquisition signal is input from 8, the number N of missiles of the relevant future tanks 20 and 22 is restored to its initial value or by a predetermined amount. Here, when the player inputs the missile item acquisition signal of the future tank 20, the player future tank 2
The number of held missiles of 0 is set to the initial state N = 6. Similarly, when the missile item acquisition signal from the enemy future tank 22 is input, the number of missiles held by the enemy future tank 22 is N =
Restore the initial value of 4.

The shield remaining amount calculation unit 122 functions as damage amount accumulating means for accumulating the amount of damage caused by the opponent's attack item each time the attack from the opponents of both future tanks 20 and 22 is determined to be effective. Is configured to. Specifically, the shield remaining amount calculation unit 122
Damage table 132 and damage amount determination unit 134
And a shield amount updating unit 136.

The damage table 132 is configured as a memory in which data for determining the amount of damage when the future tanks 20 and 22 are attacked by the opponent's future tank is stored.

In FIGS. 8A and 8B, each of the future tanks 20 stored in advance in the damage table 132,
An example of the damaged table 22 is shown. Here, in order to simplify the explanation, each of the future tanks 20, 22
However, only the amount of damage when a missile attack is performed by the opponent's tank will be described as an example, and the description of the amount of damage when a machine gun attack is performed is omitted.

In the embodiment, the damage amount X of each future tank 20, 22 due to the missile attack is expressed by the following equation.

X = D + d Here, as shown in FIGS. 8A and 8B, the value of the damage component d of each future tank 20, 22 is always set to a constant value 200 regardless of the number N of missiles possessed. Has been done. On the other hand, the value of the damage component D is 2 for each future tank.
The number of missiles N of 0 and 22 changes, and as the value of N decreases, the value of D also decreases. For example, in the case of the future tank 200, when the maximum number of missiles held is 6 and the missile remaining amount is N, the value of the damage component D is D = 200 × N / 6. The value of D also decreases as the missile remaining capacity decreases.

Therefore, it is understood that the value of the damage amount X when the missile attack is performed becomes smaller as the number of missiles held decreases.

Similarly, the damage component D of the enemy future tank 22
For the value of, the maximum number of missiles held is 4 and the number of missiles currently held (missile remaining amount) N is used, and D = 300 × N
It is represented by / 4. Therefore, when a missile attack from the opponent's future tank 20 is received, it is understood that the damage amount X decreases as the number of missiles held decreases.

The damage amount determining unit 134 is configured to function as damage amount calculating means together with the damage table 132. Specifically, Future Tank 2
As the remaining number of missile items 0 and 22 decreases, the amount of damage caused by the attack of the opponent's missile item is set smaller. That is, the damage amount determination unit 134 of the embodiment uses the hit check signal input from the hit check unit 124 and the value of the missile remaining amount N input from the owned missile counter unit 130 to determine the future tank from the damage table 132. The corresponding damage amount X of 20 and 22 is read and output to the shield amount updating unit 136. For example, when a hit check signal that the missile fired by the enemy future tank 22 hits the player future tank 20 is input from the hit check 124, the owned missile counter unit 1
The number N of missiles of the player's future tank 20 output by 30
The damage amount X corresponding to the number N of held missiles is read from the damage table 132, and is output to the shield amount updating unit 136. Specifically, when the number of held missiles is N = 4, the damage amount 334 corresponding to this is read from the damage table 132 and output to the shield amount updating unit 136.

Similarly, from the hit check unit 124, the missile fired by the player's future tank 20 is changed to the enemy future tank 2
When the hit check signal that hits 2 is input, the damage amount X to be answered from the damage table shown in FIG. 8B is read based on the value of the number N of missiles possessed by the enemy future tank 22 and the shield amount is updated. Output to the unit 136.

The shield amount updating unit 136 is used for the future tank 2
Set the initial shield amount of 0,22 in advance,
Each time a hit check signal indicating that a missile attack is hit by the opponent is input, the damage amount X output from the damage amount determination unit 134 is sequentially subtracted from the initial shield amount, and the value is calculated for each future tank 20. , 22 as the remaining shield amount. In the example, the initial shield value of each future tank 20, 22 is 200.
It is set to 0. Then, for example, when a hit check signal indicating that the missile fired by the enemy future tank 22 hits the player future tank 20 is input from the hit check unit 124 to the damage amount determination unit 134 and the shield amount update unit 136, this When the damage amount determination unit 13
The damage amount X of the future tank 20 output from 4 is subtracted from the current shield remaining amount of the future tank 20, and the subtracted value is output as a new shield remaining amount.

From the hit check section 124, the missile fired by the player's future tank 20 is changed to the enemy future tank 22.
When the hit check signal indicating that the target has been hit is output, the shield amount updating unit 136 similarly subtracts the damage amount X output from the damage amount determining unit 134 from the shield remaining amount of the enemy future tank 22. The value will be output as the shield remaining amount of the new enemy future tank 22.

When the shield item acquisition signal of the future tanks 20 and 22 is input from the item acquisition determination unit 128, the shield amount updating unit 136 sets the shield remaining amount of the corresponding future tank to the initial value 2000 or to some value. It is formed so as to perform a shield amount recovery calculation for constant recovery.

FIG. 9 shows an operation flowchart of the game apparatus of the embodiment.

Here, in order to simplify the explanation,
The operation of the player's future tank 20 will be mainly described.

First, when the game starts, the future tank 2
The shield amount of 2 is set to the initial value 2000 (step S ₁₀ ), and the missile to be held is also set to the maximum value N = 6 (step S ₁₂ ).

Therefore, the display 11 shown in FIG.
The shield display portion 26a of 0 indicates that the shield amount is fully set, and the aim 30 that also serves as the remaining missile amount has six missiles, which means that the six missiles are fully equipped. Missile symbols 31-1, 31-
2 ... 31-6 is displayed. At this time, the shield remaining amount of the enemy future tank 22 is also fully set, and the number of missiles to be equipped is also set to the maximum number N = 4.

When the game starts, the future tank 20
It moves around in the game field 60 according to the control of the player, and attacks the enemy future tank 22. And
As shown in FIG. 6, the enemy future tank 2 is displayed in the display 110.
When 2 appears, aim at the enemy future tank 22 with the aim 30, turn on the trigger 18 for missile launch,
Attack the enemy (step S ₂₀ ). This allows
The number of missiles of the future tank 20 is reduced from 6 to 5 (step S ₂₂ ), and the enemy future tank 22 is caused to explode based on whether or not the missiles hit the enemy. operation is performed (step S _24).

During such a battle, the enemy future tank 2
When the missile fired by 2 hits the player's future tank 20 (step S ₁₄ ), the damage amount determination unit 134 causes the damage amount X corresponding to the number N of missiles held by the future tank 20 to be X.
Is read from the table 132 (step S ₁₆ ), and the shield amount updating unit 136 subtracts the damage amount X from the current shield remaining amount of the future tank 20 to obtain a new shield remaining amount, and the shield display unit 26 a of the display 110.
Display on top. For example, if the future tank 20 has a shield remaining amount of 2000 and the number of missiles is N = 5, and a missile attack of an enemy is received, from the damage table shown in FIG. The damage amount X = 367 is called and subtracted from the shield remaining amount 2000. Then, the subtracted value 1633 is displayed on the shield display portion 26a as a new shield remaining amount.

In the present embodiment, when the number N of missiles possessed by the future tank 20 is large, when a missile attack by an enemy is received, the amount of damage suffered is relatively large. However, the number of missiles held N
As the number of missiles decreases, the amount of damage received when an enemy missile is attacked decreases, and the rate of reduction in the amount of shield remaining also decreases. For example, if you miss out on a missile in a battle with an enemy, the amount of damage caused by the enemy's missile attack will be X = 200, as shown in 18 (A), and damage will occur when the missile is fully equipped. Quantity X
= Half of 400.

Therefore, when the remaining number of missiles of the player future tank 200 becomes small, or when all the missiles are shot out and the player futuristic tank 200 escapes from the opponent in battle to obtain the missile item 80, the future player tank 200 is destroyed. It is possible to greatly reduce the probability of occurrence of such a situation.

For example, assume that the player's future tank has a shield remaining amount of 400, as shown in FIG.

When the player's future tank 200 is fully equipped with missiles, that is, when N = 6, when the enemy missile is attacked, the damage amount is X = 400, so one missile is missed. The attack destroys the player's future tank.

On the other hand, when the number of missiles possessed by the future tank 20 of the player is N = 0, even if an enemy's missile attack is received, the damage amount is X = 200, so the enemy's missile is If you do not hit twice, the remaining shield will not reach 0. Therefore, when escaping from the enemy to obtain the missile item 84, the probability of being attacked by the enemy is reduced.

The same thing can be said for the enemy future tank 22.

In this way, according to this embodiment, when the future tanks 20 and 22 have completely shot out the missiles, they are destroyed when they escape from the opponent in battle to obtain the missile item 84. It is possible to reduce the probability and increase the probability that the win or loss of both parties will be settled when fighting each other, thereby greatly increasing the fun as a competitive game.

When the player's future tank 20 or enemy future tank 22 acquires the shield item 86 during the game (step S ₂₀ ), the future tank's shield remaining amount reaches the initial value of 2000. It is restored set (step S _30).

When the player future tank 20 or the enemy future tank 22 acquires the missile item 84 (step S ₃₂ ), the missile remaining amount of the future tank concerned is an initial value (in the case of the future tank 20, N = 6, In the case of the enemy future tank 22, N = 4) will be set for recovery (step _S34 ).

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

For example, in the above-described embodiment, a game in which two future tanks are competing in a three-dimensional game space has been described as an example. However, a certain player character appears in the game space. The present invention can be applied to a game in which a player uses an attacking item against an enemy, and various battle games other than this.

In the above-described embodiment, the case of playing a single-player game has been mainly described as an example. However, in the case of playing a multi-player game, for example, the damage amount of each player is calculated individually and the other damage amount is calculated. Since it may be configured to be transmitted to the game device, it is not necessary to calculate the damage amount of the enemy future tank.

In the above embodiment, the case where a missile, a machine gun or the like is used as an attack item has been described as an example. However, the present invention is not limited to this, and for a game using an attack item other than this. Can also be applied.

Further, the present invention can be applied not only to a game device for business use but also to a game device for home use, for example. Further, it can be applied to a large attraction type game device in which a large number of players participate.

Further, in the present invention, the arithmetic processing performed in the game space arithmetic unit, the image synthesizing unit and the like may be performed using a dedicated image processing device, or a general-purpose microcomputer, DSP or the like may be used. It may be processed by software.

Further, according to the present invention, a display called a head mounted display (HMD) may be used as the display.

Further, in the above embodiment, the case of playing a game in a three-dimensional space has been described as an example, but the present invention is not limited to this, and for a game device of a type in which a game screen is formed two-dimensionally. However, it goes without saying that it is applicable.
