DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a game system and an information storage medium.

[0002]

2. Description of the Related Art In an action game, an inexperienced player such as a small child often encounters a situation where operations and required techniques are too difficult to complete or advance. In such a case, there is no other choice but to give up the game or to have a third party, such as an adult, replace the game and clear the game or proceed with the game.

However, in this case, an inexperienced player cannot enjoy the game to the end.

In a difficult situation, a player must be replaced with a third party, so that he cannot respect the player's willingness to enjoy the game by himself. This will cause the player's feelings to be flooded.

On the other hand, in a conventional 2D action game, there is a type in which two players simultaneously operate equal characters having the same ability to progress the game. However, when the two players had a great difference in game technique, the inexperienced player could not follow the opponent's operation and could not enjoy the game.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to provide an action game that is devised so that even an inexperienced player can independently enjoy the game. It is an object of the present invention to provide a game system and an information storage medium in which one player can play happily in a format supporting the other.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a game system for generating an image, wherein an input from a first operation means and an input from a second operation means are received in parallel with a main character and a main character. Game calculation means for performing a game calculation of a game in which a sub character having a function of supporting a game appears, and image generation means for generating a game image including a main character and a sub character based on the game calculation result, The game calculation means includes means for calculating the movement of the main character in association with the input from the first operation means, and means for calculating the movement of the slave character in association with the input from the second operation means. It is characterized by.

[0008] An information storage medium according to the present invention is an information storage medium usable by a computer, and includes a program for executing the above means. Further, a program according to the present invention is a program usable by a computer (including a program embodied in an information storage medium or a carrier wave), and includes a module for executing the above means.

In the game system according to the present invention, the first player makes an operation input to the main character from the first operation means, and the second player makes an operation input to the sub character supporting the main character from the second operation means. , The second player can simultaneously enjoy the action game while supporting the first player.

Therefore, according to the present invention, it is possible to provide a game system in which even an inexperienced player can independently enjoy the game to the end.

The game system, the information storage medium, and the program according to the present invention are characterized in that the position of the sub character follows the position of the main character.

The following may be realized by restricting the moving range of the slave character, or may be realized by forcibly moving the slave character near the main character.

[0013] Even if it does not always follow, it suffices if it follows as a result. For example, when a predetermined condition is established, the moving range of the character may be limited, or forced movement may be performed.

In this way, if a camera work is set around the main character, the main character and the sub character can be automatically captured on the same screen. Therefore, camera work for simultaneously capturing two characters on the screen is facilitated.

Further, the game system, the information storage medium, and the program according to the present invention are characterized in that a movable range of a sub character is set based on a position of a main character, and the sub character is moved within the movable range. I do.

The moving range is set based on at least the position of the main character. For example, it may be within a predetermined range of the main character, or may be determined based on the main character and surrounding terrain.

For example, it is preferable that the movable range is set within a predetermined range around the main character. By doing so, the sub character can always be present within the predetermined range of the main character.

Therefore, if the camera work is set around the main character, the main character and the sub character can be automatically captured on the same screen. This facilitates camera work for simultaneously capturing two characters on the screen.

Further, the game system, the information storage medium, and the program according to the present invention are characterized in that a subordinate character is forcibly or automatically moved within a predetermined range of a main character based on occurrence of a predetermined event.

The predetermined event is, for example, a case where the position of the slave character and the position of the main character are too far apart by a predetermined distance or more due to the movement of the main character, or a case where the main character moves instantaneously. In such a case, it is preferable that the slave character be forcibly or automatically moved within a predetermined range of the main character. By doing so, the sub character can always be present within the predetermined range of the main character.

Therefore, if the camera work is set around the main character, the main character and the sub character can be automatically captured on the same screen. This facilitates camera work for simultaneously capturing two characters on the screen.

Further, the game system, the information storage medium and the program according to the present invention are characterized in that the arrangement of the virtual camera is determined based on the position of the main character.

The arrangement of the virtual camera includes position, direction, rotation, and the like. When a plurality of characters appear, it is difficult to set the camera work. However, since the main character of the game is the main character, setting the virtual camera based on the position of the main character can facilitate camera work.

Further, the game system, the information storage medium and the program according to the present invention are characterized in that the dependent character has a function of making the enemy unable to attack or act for a predetermined time.

When the enemy is unable to attack or act for a predetermined time, the main character can easily attack the enemy or escape from the enemy during that time. However, since the enemy itself is not lost, the main character can be supported without violating the territory of the main character.

The game system, the information storage medium, and the program according to the present invention are characterized in that the sub character has a function of supporting the main character to move to a position advantageous in the game.

The advantageous position in the game includes, for example, a position where an enemy is attacked, a position where escape is difficult, a position which is advantageous when attacking an enemy, and a position where it is easy to obtain items or treasures in the game. is there.

The slave character can move the main character to a position advantageous in the game by, for example, flipping the main character at a predetermined timing. By doing so, it is possible to provide a game system capable of assisting an inexperienced player in the progress of the game by operating the slave character by another player.

The game system, the information storage medium and the program according to the present invention are characterized in that the support function of the subordinate character is disabled for a predetermined time immediately after the support.

If support is always possible, the main character becomes too advantageous, which may impair the game characteristics.

According to the present invention, by disabling the support function of the subordinate character for a predetermined time immediately after the support, it is possible to prevent the main character from becoming too advantageous and prevent the game performance from being impaired. .

Further, the game system, the information storage medium and the program according to the present invention are characterized in that the slave character automatically follows the main character when there is no input from the second operation means.

In this way, when support is not required, there is no need to input an operation, and only when support is required, an operation on the subordinate character may be performed.

Therefore, for example, a third party can advance the game in a form of helping an inexperienced player as needed.

When there is no input from the second operation means, the sub character may be displayed in a translucent manner to distinguish it from the normal state.

The game system, the information storage medium, and the program according to the present invention are characterized in that at least one of game over, game stage switching, and stage clear is performed based on a main character parameter.

In this manner, even when a plurality of characters appear, at least one of game over, game stage switching, and stage clear can be easily determined, so that game control can be easily performed and uniformity can be achieved. In addition, it is possible to appeal to the player that the game is being played mainly by the main character.

A game system, an information storage medium, and a program according to the present invention are characterized in that a game event is generated based on a parameter of a main character.

In this way, even when a plurality of characters appear, it is easy and uniform to determine the occurrence of a game event. Therefore, it is possible to appeal to the player that the game is being played mainly by the main character.

The game system, the information storage medium, and the program according to the present invention are characterized in that the subordinate character is in a state where it is not damaged or invincible.

It is preferable that the sub character does not affect the progress of the game except for supporting the main character. According to the present invention, it is possible to prevent the subordinate character from affecting the progress of the game by setting the subordinate character in a state in which no damage is received or an invincible state.

Further, the calculation load of the game can be reduced by omitting the damage calculation and the life calculation of the slave character.

Further, the game system, the information storage medium, and the program according to the present invention are characterized in that when the subordinate character performs the support operation, the subordinate character is moved to the support position irrespective of the obstacle on the moving path. And

By doing so, it is possible to cause the subordinate character to perform a smooth support operation.

2. Features of the present embodiment Features of the present embodiment will be described below with reference to the drawings.

FIG. 2 is a diagram for explaining the concept of the support mode according to the present embodiment. The game system has a support mode in which a main character 210 operated by an operation input from a 1P operation unit is supported by a sub character operated by an operation input from a 2P operation unit.

In the support mode, the subordinate character according to the present embodiment does not participate in the game as an equivalent to the main character, but participates in the game as an existence to support the main character. For example, the slave character supports the main character by receiving the falling main character or attacking the enemy to make it inoperable, but the slave character does not defeat the enemy. Even if the support is performed, the main character can attack the enemy, and only the main character can finally defeat the enemy. Therefore, the independence of the player who operates the main character can be respected, and even an inexperienced player who is not good at the action game and gets stuck can enjoy the game independently until the end.

Next, a method of operating the main character and the sub character will be described.

FIG. 3 shows an example of the 1P, 2P operation section 250. As shown in the figure, a cross key 260, a first button 270, and a second button 280 are provided. The configuration of the operation unit is the same for both the main character and the sub character. The selection of the main character from the operation unit functions as a 1P operation unit, and the selection of a sub character functions as a 2P operation unit.

FIGS. 4A, 4B, and 4C are diagrams for explaining a method of operating the main character.

When the left part of the four-way controller is pressed, the main character moves leftward, when the right part is pressed, the main character moves rightward, when the upper part is pressed, the main character faces the back, and the lower part moves down. When pressed, the main character faces forward (see FIG. 4A).

The first button functions as a jump button, and when pressed, the main character jumps (FIG. 4).
(B)). The second button functions as a shot button, and when pressed, the main character shoots a shot to catch an enemy or to throw the captured enemy (FIG. 4).
(C)).

FIGS. 5A, 5B, and 5C are diagrams for explaining a method of operating a subordinate character.

When the left part of the cross key is pressed, the slave character moves leftward, when the right part is pressed, the slave character moves rightward. When pressed, the slave character faces forward (see FIG. 5A).

The first button functions as a jump button, and when pressed, the slave character jumps (see FIG. 5B). Pressing continuously allows the slave character to fly in the sky. The second button functions as a support button, and is used when the subordinate character supports the main character like a support jump (see FIG. 5C).

Next, movement of the sub character, which is one of the features in the support mode, will be described.

In an action game using 3D polygons, when two players play at the same time, it is difficult to set a camera work for capturing two characters on the screen at the same time. For example, if two characters advance in the left and right directions and the front and rear directions in the 3D field, it is necessary to pull the camera considerably in order to capture both characters on the screen. As a result, the characters displayed on the screen are It can be as big as a bean grain.

Further, a more difficult problem arises, for example, when a character that has advanced in the depth direction is hidden by the shadow of a building.

In the present embodiment, the above problem is solved by providing the following restrictions on the movement of the subordinate character.

In principle, the position of the slave character follows the position of the main character. That is, the slave character can move on the route in the same manner as the main character. Then press the jump button to jump,
You can fly in the sky by hitting repeatedly. However, when scrolling out or moving away from the main character by a certain distance, the player is automatically pulled back to the position where the main character is. Here, scrolling out means, for example, that the slave character comes out of the screen or out of the viewable range.

FIGS. 6A and 6B are diagrams for explaining the feature of the movement of the sub character according to the present embodiment.

The slave character 320 'appears in a translucent state (ghost state) by pressing a start button (the first button functions as a start button) of the 2P operation section. The ghost slave character 320 ′ automatically moves after the main character 310 (see FIG. 6A). When the slave character 320 'is in the ghost state, no hit is made with other objects in the screen.

When a key input is performed from the operation section of the 2P operation section, the subordinate character 320 is substantiated and can act (see FIG. 6B). However, as described later, the sub character is restricted in movement, and consequently moves on the same route as the main character 310.

FIGS. 7A to 7D are diagrams for explaining the relationship between the restriction on the movement of the slave character and the camera work.

Reference numeral 310 denotes a main character, 320 denotes a sub character, and 300 denotes a screen captured by the virtual camera. As shown in FIG. 7A, the virtual camera always captures the main character at the center of the screen 300. Therefore, as a result of the movement of the main character, a situation in which the sub character scrolls out of the screen may occur.

Therefore, as shown in FIG. 7B, if a situation occurs where the slave character 320 scrolls out of the screen or a situation where the slave character 320 is separated from the main character 310 by a predetermined distance or more, as shown in FIG. The character enters a ghost state 320 ', and is forcibly moved to a position where the main character 310 is present. In this case, the ghost state is maintained until a new key input is made from the 2P operation unit.

As shown in FIG. 7D, the main character 31
In the state in which 0 is stopped, the slave character 320 can only move to the edge of the screen 300,
You can't go outside. As described above, in the present embodiment, the scroll-out of the sub character 320 is configured to occur only by the movement of the main character.

FIG. 8 is a diagram for explaining the movable range of the sub character when the main character 310 and the sub character 320 are on the moving floor 330. The moving floor 330 moves the floor itself, and an object on the floor moves together with the floor.

The movement on the moving floor 330 is basically processed in the same manner as the main character 310. However, since the slave character 320 can fly in the sky, the transparent wall 340
Enclose the moving floor with so that it cannot go outside of the range.
That is, the transparent wall 340 is set as a movable range of the subordinate character, and a process of restricting the movable range of the subordinate character 320 within the range is performed.

Next, a function for the subordinate character to support the main character will be described.

FIGS. 9A to 9E are diagrams for explaining forced movement of the subordinate character under special circumstances.

Before the main character 310 enters the cannon 360, the slave character performs a normal operation (FIG. 9A).
reference). However, when the main character 310 enters the cannon 360 (see FIG. 9B), the sub character also enters a ghost state and is forcibly moved to the cannon 360 (see FIG. 9C).

Then, the sub character 320 moves behind the main character 310 in the ghost state (FIG. 9).
(D)). During this time, the slave character cannot be operated from the 2P operation. When the main character 310 lands, the sub character 320 returns to the normal state (FIG. 9).
(E)).

As described above, when the main character 310 moves instantly and largely, the slave character 320 is also forcibly moved along with the main character 310. As a result, the sub character 320 becomes the main character 31
It is prevented from separating from zero.

FIGS. 10A, 10B, and 10C are diagrams for explaining the attack function of the subordinate character.

The subordinate character 320 is the enemy 3 with good timing.
By stepping on 50, the enemy 350 can be stunned (see FIG. 10A). Each enemy has a timing to stun, and in the case of 350, it is the moment when the face is appearing.

Then, the enemy 350 stolen is stunned and cannot move until returning after a certain period of time. During this time, the enemy 350 cannot act.
Can easily catch an enemy (Fig. 10
(C)).

As described above, the subordinate character 320 cannot completely defeat the enemy but can be temporarily disabled, thereby leading the main character to the game in an advantageous manner.

FIGS. 11A, 11B, 11C, and 11D are diagrams for explaining the support jump of the subordinate character.

As shown in FIG. 11A, the main character 3
When the support button (the second button) is pressed with the 2P operation unit when the player steps off the foot, the subordinate character 320 automatically becomes the main character 310 as shown in FIG.
It moves instantly underneath. At this time, no hit is taken between the slave character 320 and the terrain.

When the sub character 320 catches up with the main character, as shown in FIG.
Push 10 into the sky. If the main character 310 successfully lands on the scaffold, the rescue is completed. However, if the timing of pressing the support button is delayed, the slave character cannot move to just below the main character in time.
10 may not reach the scaffold.

As described above, when the 2P operation section presses the support button, the sub character 320 moves at a high speed immediately below the main character 310, and can flick the main character 310 upward. This makes the main character 3
10 can help drop.

[0120] The sub character 320 is the main character 310.
Is pushed out of the way and becomes inoperable for a few seconds (Fig. 1
1 (D)), and then it is in a ghost state and is forcibly moved to the place where the main character is.

Thus, even if the support button is fired continuously, the support jump cannot be continuously activated. This prevents loss of gameplay due to excessive support actions.

Further, a characteristic of the subordinate character is that it is invincible. The supporting character that has materialized takes a hit with the enemy or the terrain. However, the slave character is not lost even if it is damaged by the enemy or the terrain. When it is damaged, it becomes inoperable and cannot be operated for a certain period of time. At this time, the support button cannot be used as well as the movement.

However, if the main character has been killed, the subordinate character also shares fate with the main character.

In the present embodiment, events that greatly influence the progress of the game, such as game over and game stage switching, are configured to be generated based on the parameters of the main character. Thereby, even if the subordinate character is invincible, the main character can be supported without greatly affecting the progress of the game.

[0125] 3. 12 to 14 are flowcharts for explaining an example of the processing of the motion calculation of the subordinate character in the support mode according to the present embodiment.

First, it is determined whether or not the main character is over the game. If the main character is over the game, the slave character is forcibly made over the game (steps S10 and S20). Here, whether or not the main character is over the game is determined based on whether the life value, which is one of the parameters of the main character, is 0 or not. By doing so, the slave character will share fate with the main character.

Next, it is determined whether or not the subordinate character is performing the support operation. If the support operation is being performed, the subordinate character performs the support operation. At this time, the slave character is moved in the direction of the main character ignoring the hit between the slave character and the background (step S40).

The term "during support operation" means a period from when the support button of the 2P operation section is pressed to when the support operation is completed. When the support button is pressed, the support flag is set to 1
Is set, it can be determined whether or not the support operation is being performed based on whether or not the support flag is set to 1.

When the support button of the 2P operation section is pressed, the support flag is set to 1 and the success or failure of the support operation is determined at the timing of pressing the support button, and the sub character performs the support operation according to the success or failure. Will be.

When the support operation is completed, the blank time value is set in the post-support blanking time counter and the support flag is set to 0 (step S5).
0, S60, S70). The post-support blanking time counter is a counter for counting the disabled period of the sub character after the support, and the sub character is inoperable for the blank time value set after the support operation is completed.

If the blanking time after the end of the support operation is in progress, the post-support blanking time counter is counted down to disable the subordinate character (steps S80, S90, S100).

In the forced position movement mode, the slave character is moved to the designated forced position (mainly in the vicinity of the character) (steps S110 and S110).
