Abstract: A non-transitory computer-readable medium including a program for causing a server to realize functions to control progress of a video game including a three-dimensional virtual space, the three-dimensional virtual space having a boundary through which a player character is allowed to move to another three-dimensional virtual space is provided. The functions include: a specifying function configured to specify a position of the player character in the three-dimensional virtual space; and a displaying function configured to change a scare of a boundary object on the basis of the position of the player character to display the boundary object, the boundary object being an object that is provided on or near the boundary. further, the displaying function includes a function configured to change a positron of the boundary object on the basis of a change in the position of the player character to display the boundary object.
