Abstract

The invention relates to a display device and an animation display method. Comprising the steps that in response to an animation display event, a virtual animation is played, a first virtual object in the virtual animation moves in a virtual environment, and the initial moving direction of the first virtual object is the direction pointing from an initial position to an end position; if it is detected that the first virtual object has the collision risk, a first rotation direction is determined, the current moving direction of the first virtual object is updated based on the first rotation direction and the first rotation speed until the collision risk is removed, and the collision risk refers to the risk that the first virtual object collides with an obstacle in the virtual environment; if it is detected that the collision risk of the first virtual object is relieved, a second rotation direction is determined according to the current moving direction and the current position of the first virtual object, and the current moving direction is corrected based on the second rotation direction and the second rotation speed so that the first virtual object can move towards the termination position. The naturalness of the animation can be improved.
