PROBLEM TO BE SOLVED: To efficiently derive a propagation passage of sound detouring a screening body.SOLUTION: A video game processing device 10A displays at least a part of a virtual space in which a sound source, a listening position and a screening body are disposed, on a display screen of a display device and controls a progress of a video game. The video game processing device: sets a detour point of sound generated from the sound source, onto the screening body; changes the detour point to a position (a floating position) floated from the screening body; determines whether or not the sound directly reaches the listening position from the floating position; when it is determined that the sound directly reaches, derives a sound propagation passage using the floating position; and generates output information related to the sound generated from the sound source on the basis of the propagation passage.SELECTED DRAWING: Figure 8 |
