Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game program executing method and a game device. In particular, the present invention relates to a game program executing method and a game device that change the content of a game over time.

[0002]

2. Description of the Related Art In recent years, a device for executing a game program using a personal computer or a game dedicated device has become widespread. There is also an increasing number of programs that change the content of the game and make the game more enjoyable by closely adhering to the living space of the player who plays the game.

Further, the game contents can be made more realistic by changing the game contents depending on the real life of the player, especially with the passage of time. However, in the existing game program execution methods and game devices, the game is executed by the fixed contents designed by the designer, and there are some that have contents that change with the passage of time. Not not.

[0004]

Therefore, according to the present invention, not only the time during which the actual game is executed but also the time during which the game is not executed can be considered as the elapsed time, and the contents of the game can be changed. An object of the present invention is to provide a method for executing a game program and a game device that realizes the method.

[0005]

SUMMARY OF THE INVENTION The present invention is a method for executing a game program by modifying the game program with the passage of time.
The elapsed time from the time when the game execution is finished first to the time when it is re-executed is measured.

Then, a subroutine that gives a change to the game program is selected in accordance with the measured elapsed time, and the game program is executed together with the selected subroutine.

When a game program is executed to give a more realistic change, a random number is generated, and a subroutine for changing the game program is selected according to a combination condition of the elapsed time and the random number. .

A game device according to the present invention has a ROM for storing the game program in order to realize the above-mentioned game program executing method, and a game cartridge having a clock function circuit. In the execution method, the elapsed time from the time when the game execution is finished first to the time when it is re-executed is given.

[0009]

According to the present invention, when the game program is executed, the elapsed time from the point of time when the game execution is finished to the time of re-execution is measured. A subroutine of the game program that gives a change to the determined amount of elapsed time is selected.

Therefore, by executing the game program together with the selected sub-routine, it becomes possible to execute the game program which is changed in accordance with the passage of time.

Further, the present invention uses a game cartridge having a ROM for storing a game program and a clock function circuit. As a result, it is possible to give an elapsed time from the time when the clock function circuit first ends the game execution to the re-execution. Therefore, it is possible to select a subroutine that changes the game program corresponding to the elapsed time.

FIG. 1 is a block diagram of an embodiment of the present invention. In the figure, 1 is a game apparatus main body, and 2 is a game cartridge. The game device body 1 is BUS
Has a plurality of device elements connected to it. That is, CPU1
0, RAM 11, image processing circuit 12, audio processing circuit 13
And the sequence counter 14 is connected to the BUS.

Further, the BUS is connected to an operating device 3 provided outside the game apparatus main body 1 and operated by a player. Further, the TV monitor 4 is connected to the image processing circuit 12 and the audio processing circuit 13, and displays the image data and audio data from the respective circuits.

The game cartridge 2 can be connected to and disconnected from the game apparatus main body 1 by a connector. Similarly, a BUS is provided in the game cartridge 2, and the ROM 20 fixedly stores the game program.
And a buffer memory 21, and a clock function circuit 22 provided by the present invention is connected to the BUS.

Next, FIG. 2 is an operation flow of the embodiment of the present invention. In particular, based on the game program stored in the ROM 20 in the game cartridge 2, the C of the game apparatus main body 1 is displayed.
The operation flow controlled by PU10 is shown.

Further, FIG. 3 is a diagram for explaining the operation of the embodiment of the present invention. The following is the contents of the example of the game program:
The operation of the present invention will be described by taking a game of raising fish in an aquarium as an example.

Here, the game of growing fish in the aquarium is a TV
This is a game in which a simulated aquarium is displayed on the monitor and multiple fish are swim and raised in this aquarium. This is a game in which a game program gives an image such that the fish in the aquarium swims in each direction or moves or the movement of the fish in the aquarium changes by feeding.

In such a game of growing fish in the aquarium, the game program stored in the ROM 20 of the game cartridge 2 has data so that the fish in the aquarium may be given a certain movement in the aquarium. Is made.

In such a game, the emphasis is placed on displaying an aquarium on the TV monitor 4 and displaying moving fish to be cultivated in the aquarium exclusively for the player's pseudo viewing.

Therefore, when the game program completes one cycle, the fish in the aquarium again moves in the same manner as the previous one. In such a case, the player can temporarily enjoy watching the fish in the simulated aquarium. However, with the passage of time, the movement of the fish in the aquarium is predicted in advance, which results in the interest in the game being halved over time.

From this point of view, the present invention is to execute a game program that changes the contents of the game program over time so as not to easily lose the interest of the player.

In the game of growing a fish in the aquarium as described above, the fish continues to grow even when the power is turned off and becomes sick, or lays an egg, and a child is laid from the egg. The game program is executed so that it can be changed. With respect to such an embodiment, an embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In FIG. 2, the game program of the present invention is started (step S1), and elapsed time is measured (step S2). At the same time, a random number is generated based on the contents of the game program (step S3). Here, the determination of the elapsed time is to obtain the time until the game is finished and the game is executed again.

This time lapse is obtained by the clock function circuit 22 in the cartridge 2. Therefore, the cartridge 2
Even when the game is disconnected from the game apparatus body 1 that executed the game and connected to another game apparatus body, the game cartridge 2 is connected to the time when the game was executed in the previous game apparatus body 1 and to the other body apparatus. Then, the time until the game is re-executed can be continuously obtained.

On the other hand, the random number generation (step S3) is performed by RO
It is a random number appropriately generated by the game program provided in M20, and means, for example, randomly generating any one of ten numbers 1 to 0. Next, the subroutine SR is selected from the measured elapsed time and the generated random number (step S
4).

That is, immediately after the start of the game, the passage of time is close to 0, so that the subroutine SR11 of fish size setting 1 is selected regardless of the random number generated. This sub-routine SR11 sets the size of a predetermined fish,
Next, the watching fish breeding program is executed (step S
5).

As described above, the contents of the watching fish breeding program execution (step S5) are, for example, as shown in FIGS. 3 (1) and 3 (2).
As can be understood by comparison with the above, it is possible to express the state of swimming of the fish in the process of rearing the fish in the simulated aquarium by variously changing the position of the fish in the aquarium.

Also, a subroutine SR for fish size setting 1
The appreciation fish breeding program is executed according to the size determined by 11, for example, the size of the fish as shown in FIG. 3 (1) (step S5). When the viewing fish breeding program execution (step S5) is completed, the operation flow returns to the start position.

Next, the lapse of time is measured again in the same manner as described above (step S2). Here, the time elapsed measurement is performed by the R in the game apparatus body 1 under the control of the CPU 10 every time the viewing fish breeding program execution (step S5) is completed once.
Numerical values are added to AM11 one by one.

Therefore, by detecting the numerical value stored in the RAM 11, it is judged how many times the watching fish breeding program execution (step S5) is repeated.

This execution of the watching fish breeding program (step S5) requires a predetermined time for one execution. Therefore, the time during which the game is being played can be relatively determined from the number of times the watching fish breeding program is executed.

In the subroutine selection (step S4), a predetermined time elapses, that is, a subroutine SR12 for setting the size of the fish to be displayed in the form of a large fish in order based on the number of times the watching fish breeding program stored in the RAM 11 is executed. ..SR1n is selected.

Comparing FIG. 3 (1) with FIG. 3 (3),
The size of the swimming fish changes, that is, it is displayed as if the fish were reared and grown large.

Further, the appreciation fish breeding program (step S
5) is executed a predetermined number of times or more, that is, a random number (step S3) generated when it is determined in the time elapsed measurement (step S2) that the time elapsed from the start of the game is a predetermined time or more In response to the fish size setting, another subroutine, for example, a subroutine (SR2) that gives birth to a child or a subroutine SR3 that causes illness is selected in the subroutine selection (step S4).

When this is seen again in FIG. 3, FIG.
In (4), it is understood that the size of the fish is the largest. At the same time, more small fish are swimming. Also, a diagram is shown in which eggs are attached to the water plants in the aquarium.

As described above, in the actual breeding of ornamental fish, the size of the fish grows with breeding over time, and sometimes there are changes such as egg laying and fish laying from the egg. Is possible.

In the embodiment of the present invention, as described above, the game cartridge is provided with the clock function circuit 22 as shown in FIG. 1 in order to execute the game program in synchronization with the actual life time of the player.

That is, the clock function circuit 22 is a clock driven by a power source (not shown) in the game cartridge and has a function of always indicating elapsed time. Therefore CPU
Numeral 10 can be converted into a relative number of times the watching fish breeding program is executed by detecting the passage of time displayed on the clock function circuit 22.

As a result, for example, even when the watching fish breeding game is interrupted and the power of the game apparatus main body 1 is turned off, the clock function circuit 22 of the game cartridge displays the progress of the real time as the real time passes. It will be.

Therefore, when the game apparatus body 1 is turned on again and the game is to be executed again, the CPU 10 causes the RAM 1
The output of the clock function circuit 22 of the game cartridge 2 is detected instead of the number of times the watching fish breeding program is stored in 1.

The appreciation fish breeding program (step S
From the execution time of 5), the time when the power is turned off is stored in the RAM 11 as the number of times the viewing fish breeding program was actually executed.

It is assumed that the game cartridge 2 which is now connected to the game apparatus main body 1 is removed, the game cartridge 2 is moved from the home to the workplace, connected to the game apparatus main body in the workplace, and the game is started again. .

Even in such a case, since the clock function circuit 22 is provided in the game cartridge 2, the elapsed time from the time at home to the time at work can be obtained by the clock function circuit 22. Therefore, the game is re-executed with a change considering the elapsed time.

In addition to the case where the game cartridge 2 is separated from the predetermined main body apparatus 1 and connected to another main body apparatus as described above, and when the game cartridge 2 is used semi-fixedly and integrally with the specific main body apparatus 1. It is not always necessary to provide the clock function circuit 22 in the game cartridge 2. In such a case, the main body device 1 is provided with, for example, a sequence counter 14, and it is possible to obtain the elapsed time by this.

Although the present invention has been described according to the above embodiments, the present invention is not limited to the game of raising fish in the aquarium of the embodiments, and can be applied to, for example, a game program in which an appearing character passes with time. It is possible.

It is also applicable to a program in which the terrain changes with time, or changes such that the tide is filled or pulled. Further, the present invention is not limited to such a program, and those having the same idea as the present invention are included in the protection scope of the present invention.

[0047]

As described above according to the embodiments of the present invention, the present invention allows the game to be restarted next even when the power is turned off by incorporating the clock function circuit in the cartridge 2 or the main body device 1. It is possible to determine the elapsed time until.

As a result, it is possible to change the game program in consideration of this elapsed time. Therefore, the execution of the game program can be made more attractive to the player.
