Animation and physics synchronization

Abstract:

This specification relates to animation and physics updates in computer games. According to a first aspect of this disclosure, there is described a computer implemented method comprising: updating, using an animation engine, an in-game animation at a first rate; and updating, using an in-game physics engine, an in-game physics state at a second rate, the second rate being different to the first rate. Updating the in-game physics state comprises: interpolating one or more in-game physical parameters corresponding to a physics update time that lies between two consecutive animation update times, the interpolation based on in-game animation frames corresponding to the two consecutive animation update times; and determining the update to the in-game physics state based on the interpolated physical parameters.
