Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game apparatus for achieving a desired object by operating a variable speed moving object.
The present invention relates to an information recording medium and a method for displaying a moving object.

[0002]

2. Description of the Related Art In recent years, many video games have been provided to the market by applying image processing technology and image display technology using computers to the entertainment field. Video games are generally played by a game player operating a character image displayed on a display device. Video games can be classified into various genres based on the game content.

[0003] As a genre of video games, an action game (hereinafter referred to as AC
G; ACtion Game), an adventure game that advances the game by command input (hereinafter, ADG; ADventure Ga)
me), a simulation game that simulates various events (hereinafter, SLG; SimuLation Game), and a role-playing game (hereinafter, RPG; Role Playing Gam) that advances the game while growing a character set by yourself.
e) etc.

[0004] In addition, each genre such as ACG, ADG, SLG, and RPG includes a small genre. For example, in ACG, a shooting game (hereinafter, STG: Shooting Game) for destroying a target, thinking There are games of genres such as a thinking puzzle game requiring power, a sports game imitating various sports (hereinafter, SPG; SPorts Game), and a pinball game imitating a pinball.

[0005]

2. Description of the Related Art Characters that can be operated by a game player (hereinafter referred to as operation target characters) include those that move at a constant speed in response to an operation and those that move at a variable speed. The difference between these character movements is
Generally, it is determined according to the game genre and the game content. For example, in most RPGs, the main character is moved at a constant speed due to operability. Also, among the ACGs, many of the genres classified as STG change the moving speed of the operation target character in a stepwise manner for the reasons described below.

That is, most of the general STG game contents have a simple rule of destroying an enemy while avoiding an attack from the enemy. Therefore, the faster the moving speed of the operation target character is, the easier it is to escape from an enemy attack. However, as the moving speed of the operation target character increases, the character moves more than intended distance, and a slight operation error may cause a collision with an obstacle or the like. As described above, if the moving speed of the operation target character exceeds the operation skill of the game player and becomes too fast, the character operation becomes extremely difficult.

[0007] As described above, in the STG, it is preferable that an appropriate moving speed can be selected in accordance with the user's operation skill and the game situation. Therefore, in order to set the moving speed of the operation target character to a desired speed for each game player, the moving speed is often changed stepwise. Here, the switching of the moving speed is performed by, for example, increasing the moving speed by one step each time a button provided separately from the character operation is pressed, and sequentially increasing the moving speed again from the minimum state when the moving speed is maximized. There is something like that.

[0008]

In the case where the moving speed of the operation target character is variable, the moving speed cannot be known without actually performing the operation. For this reason, the current moving speed needs to be sensibly remembered by the operation sensation of the game player. That is, even when the moving speed changes, it is difficult to understand the change except when the moving operation is performed by the game player.

Therefore, it is conceivable to display a current moving speed by displaying a number, a symbol mark, or the like at a corner of the screen. In this case, in order to check the current moving speed, the game player must change the point of gaze from the operation target character operated by the game player to the corner of the screen. In a game of a genre such as ACG that requires a real-time operation, it may be fatal to change the gazing point from the operation target character even for a short time.

[0010]
