Patent ID: 8130196

Claim:
A game performing method for a player to control a game object by operating an operating handle which can be inclined in a desired direction, the method comprising: detecting a first position of the operating handle at a first time, the first position including a first inclined direction and a first inclined angle; detecting a second position of the operating handle at a second time later than the first time, the second position including a second inclined direction and a second inclined angle; setting a first input invalid sphere to judge whether the operating handle is not inclined beyond a predetermined inclination angle, the first input invalid sphere being centered at a center of an operable sphere of the operating handle and having a radius based on the predetermined inclination angle, the first input invalid sphere being a sphere in which the inclined angle of the operating handle is less than the predetermined inclination angle, and set within the operable sphere of the operating handle; updating and setting a second input invalid sphere to judge whether a direction of the operating handle is changed by more than a predetermined direction angle, the second input invalid sphere being a direction angle sphere for not allowing a change in the inclined direction with the detected inclined direction of the operating handle when the change in the inclined direction of the operating handle exceeds the predetermined direction angle, the second input invalid sphere being set based on the first position and the predetermined direction angle; and performing control to change a direction of the game object on the basis of the change in angle from the first inclined direction to the second inclined direction when the second inclined angle is outside of the first input invalid sphere and the second input invalid sphere.
