Abstract

PURPOSE: To vary game progress with various attach methods by providing a durability changing means for subtracting the power of a bullet stored in a second memory from the durability of an obstacle stored in a first memory and for storing the subtracted result in the first memory. CONSTITUTION: When performing an image output with a CPU circuit 7, image data are written through a video control circuit 11 and a video bus 13 into a screen memory 14. Since a monitor 3 reads out the image data, converts them to a visible image and displays it, a player advances a game while watching the visible image. On the other hand, the durability of the obstacle is managed by a work memory 9 as a variable value. When it is judged that the bullet does not exceed range and that the bullet this the obstacle and it is judged that the power of the bullet is smaller than the durability of the obstacle, the durability of the obstacle is subtracted just by the power of the bullet. Further, when it is judged that the power of the bullet is larger than the durability of the obstacle, the destroying processing of the obstacle is performed and the power of the bullet is subtracted just by the durability of the obstacle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gun shooting game machine.

[0002]

2. Description of the Related Art In a conventional gun shooting game machine,
When an obstacle that an enemy can hide is provided, the durability of the obstacle is often infinite or uniform. When the durability of an obstacle is infinite, if the enemy hides in the obstacle, the obstacle cannot be destroyed, so it is impossible to attack the hidden enemy.
Further, even if the obstacle is provided with durability, the durability is made uniform, so an attack equal to or less than the durability is wasted, and there is no change in the game progress.

[0003]

As described above, in the conventional gun shooting game machine, the durability of the obstacle is infinite or uniform, so that the game progress becomes monotonous and the attack method becomes uniform. There was a drawback to

The present invention has been made in view of the above problems, and it is an object of the present invention to make the progress of a game diversified by a variety of attack methods by making the durability of an obstacle variable.

[0005]

To achieve this object, a gun shooting game machine of the present invention comprises a first memory for storing the durability of obstacles, and a second memory for storing the power of bullets. From the durability of the obstacle stored in the first memory, the power of the bullet stored in the second memory is subtracted to obtain the first
And a durability change means for storing in a memory.

[0006]

In the gun shooting game machine having the above structure, the power of the bullet stored in the second memory is subtracted from the durability of the obstacle stored in the first memory, and the result is stored in the first memory. Therefore, the durability of the obstacle becomes a variable value. This makes it possible to diversify the method of attacking the obstacle and diversify the game progress.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block connection diagram showing an embodiment of a gun shooting game machine according to the present invention.

In FIG. 1, the video game machine comprises a coin-related device 1, an operating device 2, a monitor 3, and a speaker 5 with a TV game device 4 as a center. The coin-related device 1 communicates with the TV game device 4 (the input / output control circuit 6) and manages the number of coins to be inserted and the payout. The operation device 2 is a joystick,
Devices such as buttons and switches operated by the player. The monitor 3 converts the image output signal of the TV game device 4 into a visible image and displays it. Speaker 5 is a TV
The audio output signal of the game device 4 (sound system circuit 16) is converted into an audible sound and output.

The TV game device 4 includes an input / output control circuit 6,
It is composed of a CPU circuit 7, a video control circuit 11, a screen memory 14, a sound system circuit 16, and the like. The input / output control circuit 6 communicates with the coin-related device 1 mutually and sends information such as the number of coins to be inserted and payout to the CP.
It is transmitted to the U circuit 7. In addition, a state in which the player operates a joystick, a button, a switch and the like (operating device 2) is detected and transmitted to the CPU circuit 7. CPU circuit 7
The transmission and reception of signals to and from are performed via the system bus 8.
The work memory 9 is used as a work area of the CPU circuit 7. The program of the CPU circuit 7 is stored in the program memory 10.

When the CPU circuit 7 outputs an image,
Image data is written to the screen memory 14 via the video control circuit 11 and the video bus 13. Monitor 3
Reads the image data written in the screen memory 14, converts it into a visible image, and displays it. The player is
The game proceeds while watching the visible image on the monitor 3.

When the CPU circuit 7 outputs a voice,
The audio data is output to the sound system circuit 16 via the dual port RAM 15. The sound system circuit 16 performs audio signal processing, generates an analog audio output signal, and outputs the analog audio output signal to the speaker 5. The speaker 5 outputs the audio output signal of the sound system circuit 16 as an audible sound. The player advances the game while listening to the sound output from the speaker 5.

FIG. 2 is a flow chart showing a subroutine of the program of the CPU circuit 7, which is called from the main routine and started. When the program starts, the pumping counter is first cleared (reset). In step S2, it is determined whether the player has performed pumping. What is pumping here?
As shown in FIGS. 3A and 3B, the barrel 2 of the gun 21
This means that the pumping member 21a provided in the lower part of 1c is rotated around the hinge 21b in the arrow direction. The gun 21 is provided as a part of the operating device 2. Further, as the pumping, in addition to the rotating operation, other operations such as an operation of pressing a button and an operation of depressing a pedal can be performed.

When it is determined in step S2 that the player is not pumping, the process proceeds to step S6. When it is determined that the player has performed pumping, the process proceeds to step S3 and it is determined whether or not pumping is performed twice or more. If it is determined that the number is two or more, the pumping count is set to 2 in step S4 and then step S4 is performed.
Go to 6. When it is determined that the number is smaller than two, the pumping count is set to 1 in step S5 and the process proceeds to step S6. That is, the pumping counter is 0-2
It is set to the value up to, and pumping more than 3 times cannot be set. The pumping counter can be set to a value of 3 or more.

In step S6, game processing (FIG. 4) is performed. The game process will be described later with reference to FIG. In step S7, the number of times of pumping is checked from the pumping counter. When the number of pumping is 0,
A processing with weak destructive force is performed (step S8). When the number of times of pumping is one, B processing of medium destructive force is performed (step S9). Further, when the number of times of pumping is two, C processing of strong destructive force is performed. The degree of destructive power (power) may be the degree of damage.

Next, the game process will be described with reference to the flowchart shown in FIG.

When the program starts, the destructive power A, B, or C of the pumped gun 21 is changed to the power A of the bullet.
It is set to B or C (step S11). In step S12, it is determined whether or not the player has turned on the trigger switch (operating device 2). When it is determined that the trigger switch is off, the process returns to step S11, and when it is determined that the trigger switch is on, necessary information such as pumping power information is stored in the work memory 9 (step S13). Various statuses are stored in the work memory 9 as shown in FIG. That is, A
The obstacle durability and the B obstacle durability are managed in the work memory 9 as variable values.

In step S14, a bullet is fired and flight processing of the bullet is performed (step S15). In step S16, it is determined whether or not the bullet has exceeded the range. When it is determined that the bullet has exceeded the range, it is determined that the bullet has lost its power, and the information such as pumping power information stored in the work memory 9 is cleared (step S
23) and returns to the main routine (FIG. 2).

When it is determined in step S16 that the bullet does not exceed the range, it is determined that the bullet has power, and it is determined whether or not it hit an object (obstacle) (step S17). When it is determined that it has not hit, the process returns to step S15. When it is determined that the bullet has hit, it is determined whether the power of the bullet is equal to or higher than the durability of the obstacle (step S1).
8). When it is determined that the power of the bullet is smaller than the durability of the obstacle, the durability of the obstacle is subtracted by the power of the bullet (step S19). When it is determined that the power of the bullet is greater than the durability of the obstacle, the obstacle is destroyed (step S20).
At the same time, the durability of the obstacle is subtracted by the power of the bullet (step S21). If the result of the subtraction shows that the power of the bullet is negative, it is determined that the power of the bullet has disappeared and step S15 is performed.
Return to When it is determined that the power of the bullet is 0 or more, it is assumed that the power of the bullet exists, and after clearing the information such as the power information of the pumping stored in the work memory 9 (step S23), the main routine ( Return to FIG. 2).

As described above, according to the present invention, the obstacle is provided with a variable durability value. For example, assume that the following variable values are given as obstacle durability.

When the pumping is 0 times, the destructive power of the bullet A = the power of the bullet A (= 1)

With one pumping, the destructive force of the bullet B = the power of the bullet B (= 2)

When the pumping is performed twice, the destructive power C of the bullet is equal to the power C (= 3) of the bullet. Also,

When the obstacle A = endurance A (= 1) is shot with the elasticity A, B, or C, the obstacle A is destroyed.

Obstacle B = durability B (= 2), elastic force B
Or if you shoot with C, obstacle B will be destroyed.

Obstacle C = durability C (= 3), elastic force C
If you shoot with, obstacle C will be destroyed.

Obstacle D = Durability D (= 4), Elasticity C
If you shoot at, obstacle D becomes the durability of obstacle A.

Obstacle E = Durability E (= 5), Elasticity C
Obstacle E becomes the endurance of obstacle B when shot with.

Obstacle F = durability F (= 6), elastic force C
If you shoot with, obstacle F becomes the durability of obstacle C.

Here, for example, in the case of destroying the obstacle D (= 4), various attack methods are possible as follows.
That is,

The obstacle D is destroyed when it is shot four times with the elastic power A.

The obstacle D is destroyed when it is shot twice with the elastic power B.

The obstacle D is destroyed by shooting once with the elastic power B and twice with the elastic power A.

The obstacle D is destroyed by shooting once with the elastic power C and once with the elastic power A.

As described above, when destroying the obstacle D (= 4), four variations are possible, and various changes can be brought to the progress of the game.

[0036]

As described above, according to the gun shooting game machine of the present invention, the power of the bullet stored in the second memory is subtracted from the durability of the obstacle stored in the first memory, Since it is stored in the first memory, the durability of the obstacle has a variable value. This makes it possible to diversify the method of attacking obstacles and diversify the game progress.
