## Abstract

A current value guide unit of a game device shows a user a current value of one game parameter indicating a current state of an operation subject. An action control unit causes the operation subject to perform an action in response to an operation performed by the user. A game parameter changing unit causes the one game parameter to change in a case where the operation subject moves, a case where the operation subject attacks an enemy, and a case where the operation subject receives damage due to an attack from the enemy. A determination unit determines whether or not the current value of the one game parameter is within a predetermined range. An inhibition unit inhibits the operation subject from performing an action when it is determined that the current value of the one game parameter is within the predetermined range.

means for changing at least one of a position and a sight line direction of the virtual viewpoint in response to the operation performed by the user;
means for determining whether or not the operation subject is being displayed on the display means; and
means for changing the one game parameter in a case where it is determined that the operation subject is not being displayed on the display means.

### Claim 3 (depends on 1)

The game device according to claim 1, further comprising:
means for causing display means to display a virtual space image showing how the virtual space is viewed from a virtual viewpoint;
means for changing at least one of a position and a sight line direction of the virtual viewpoint in response to the operation performed by the user; and
means for determining whether or not the operation subject is being displayed on the display means,
wherein the game parameter changing means comprises means for one of increasing and decreasing a change amount of the one game parameter in a case where the operation subject is being displayed on the display means compared to a case where the operation subject is not being displayed on the display means.

### Claim 4 (depends on 1)

The game device according to claim 1, further comprising:
means for causing display means to display a virtual space image showing how the virtual space is viewed from a virtual viewpoint;
means for changing at least one of a position and a sight line direction of the virtual viewpoint in response to the operation performed by the user;
means for acquiring change amount information relating to a change amount of the one game parameter from means for storing a condition and the change amount information in association with each other, the condition relating to a positional relationship between the position of the virtual viewpoint and one of a position of the operation subject and a reference point which is set in the virtual space; and
means for determining whether or not the condition is satisfied by a current positional relationship between the position of the virtual viewpoint and the one of the position of the operation subject and the reference point,
wherein the game parameter changing means changes the one game parameter based on the change amount information associated with the condition satisfied by the current positional relationship between the position of the virtual viewpoint and the one of the position of the operation subject and the reference point.

### Claim 5 (depends on 1)

The game device according to claim 1, further comprising:

the game device further comprises means for displaying an image having substantially the same length as an expansion/contraction length of the current value gauge which is used in the case where the operation subject makes an attack in such a position that an edge part of the image corresponds to an edge part of the current value gauge.

### Claim 8

A method of controlling a game device for executing a game configured so that an operation subject of a user moves within a virtual space to attack an enemy, the method comprising:
