摘要

PROBLEM TO BE SOLVED: To express the complicated force in a game space by a simple method. SOLUTION: A wind generation part 220 sets a plurality of wind generation sources at prescribed positions in an object space and determines the wind force of the wind generated from the generation sources at every fixed time. The direction and speed of the wind generated from each generation source are made constant. A grass controller 222 calculates in what directions and to what angles grass objects are inclined by the wind generated from the generation sources.
