A virtual object control method and apparatus, a device, a medium, and a program product, relating to the technical field of computers. The method comprises: controlling a first virtual object by means of a first behavior tree, the first virtual object being a non-player character (NPC) (220); obtaining a first distance between the first virtual object and a second virtual object in a virtual environment, and a second distance between the first virtual object and a third virtual object in the virtual environment, the second virtual object being a virtual object controlled by a player, and the third virtual object being a virtual object controlled by another player (240); and when the first distance is less than the second distance, determining, on the basis of the first distance, to control the first virtual object by means of a second behavior tree, the first distance being in a negative correlation with a resource consumed by the second behavior tree during operation (260). According to the solution, when the computer device resources are limited, it is ensured that the NPC can realize abundant presentation forms.
