Storage medium storing game program and game apparatus for improved collision detection in a video game

A game apparatus comprising at least one processor and for outputting to a display device a game image showing a behavior of an object in a game space, the at least one processor controlling the game apparatus to:

• repeatedly determine whether or not a first object contacts a second object at a first point in time and at a second point in time, the second point in time being a latest result of determination stored after the first point in time;
• successively store results of the repeated determination into a memory;
• and
• perform a predetermined process with respect to the first object when, of the results of determination stored in the memory, at least one result of determination includes determining that the first object contacted the second object at the first point in time.

A game processing method executable by a game apparatus having one or more processors which outputs to a display device a game image showing a behavior of an object in a game space, the method comprising:

• repeatedly determining whether or not a first object contacts a second object at a first point in time and at a second point in time, the second point in time being a latest result of determination stored after the first point in time;
• successively storing results of the repeated determination;
• and
• performing a predetermined process with respect to the first object when, of the results of the stored determination, at least one result of determination includes determining that the first object contacted the second object at the first point in time.

A game processing system, comprising:

• a display device configured to display image data;
• and
• a game apparatus having one or more processors and configured to output to the display device a game image showing a behavior of an object in a game space, the one or more processors controlling the game apparatus to:
• repeatedly determine whether or not a first object contacts a second object at a first point in time and at a second point in time, the second point in time being a latest result of determination stored after the first point in time,
• successively store results of the repeated determination into a memory, and
• perform a predetermined process with respect to the first object when, of the results of determination stored in the memory, at least one result of determination includes determining that the first object contacted the second object at the first point in time.
