GAME DEVICE, METHOD FOR CONTROLLING THE GAME DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a game device for determining a position in a virtual three-dimensional space by relatively simple processing corresponding to screen coordinate values specified by a user.

SOLUTION: A reference point conversion section 72 coordinate-converts a plurality of reference points set in the virtual three-dimensional space into a screen coordinate system using a predetermined coordinate conversion operation. A reference point-selecting section 76 selects at least one of the pluralies of reference points based on the comparison result of the screen coordinate values specified by the user and screen coordinate values corresponding to respective reference points. A reference point-resetting section 78 resets the plurality of reference points based on the reference points selected by the reference point-selecting section 76. A game processing section 80 performs game processing based on the reference points selected by the reference point-selecting section 76 out of the plurality of reference points reset by the reference point-resetting section 78.
