  • a plurality of movement patterns F2 are set in advance for each of a plurality of situations F1 in the virtual space VS. Then, the movement determination unit 2034 determines one movement pattern F2 from the plurality of movement patterns F2 corresponding to the situation F1 in the virtual space VS in which the avatar A is placed. This configuration prevents avatar A from performing actions that a third party would find unnatural because they are inappropriate for the situation F1 of the virtual space VS in which avatar A is placed.
