Game program product, game apparatus and game method indicating a difference between altitude of a moving object and height of an on-earth object in a virtual word

A game apparatus which generates a display on a screen a virtual game space in which a land object is arranged, and a moving object moving in said virtual game space, the game apparatus comprising:

• change programmed logic circuitry for changing a movement parameter defining a movement of said moving object in response to a player's operation;
• predicting programmed logic circuitry for predicting a reaching point where said moving object will reach after a lapse of a time T (T>0) on the basis of said movement parameter;
• first detecting programmed logic circuitry for detecting at least any one of a current altitude of said moving object and an altitude of said moving object in the reaching point predicted by said predicting programmed logic circuitry;
• second detecting programmed logic circuitry for detecting a height of said land object in the reaching point predicted by said predicting programmed logic circuitry;
• and
• output programmed logic circuitry for generating an output to said player difference information indicating a difference between the altitude detected by said first detecting programmed logic circuitry and the height detected by said second detecting programmed logic circuitry.

A game method to be performed by execution of computer readable instructions, tangibly stored on a computer readable storage medium, by a game apparatus for displaying on a screen a virtual game space in which a land object is arranged, and a moving object moving in said virtual game space, the game method comprising the steps of:

• (a) changing a movement parameter defining a movement of said moving object in response to a player's operation of the game apparatus;
• (b) predicting a reaching point where said moving object will reach after a lapse of a time T (T>0) on the basis of said movement parameter;
• (c) detecting at least any one of a current altitude of said moving object and an altitude of said moving object in the reaching point predicted by said step (b);
• (d) detecting a height of said land object in the reaching point predicted by said step (b);
• and
• (e) generating an output to said player difference information indicating a difference between the altitude detected by said step (a) and the height detected by said step (d).

A computer system comprising;

• a non-transitory readable storage medium tangibly storing computer readable instructions;
• a processor configured to execute the instructions to:
• generate a display of a virtual game space in which a non-moving object is arranged, and a moving object moving in said virtual game space on a screen;
• change a movement parameter defining a movement of said moving object in response to a player's operation;
• predict a reaching point where said moving object will reach after a lapse of a time T (T>0) on the basis of said movement parameter;
• detect at least any one of a current altitude of said moving object and an altitude of said moving object in the predicted reaching point;
• detect a height of the non-moving object in the predicted reaching point;
• and
• generate an output which provides to said player difference information indicating a difference between the detected altitude and the detected height.
