TimeListener
interface TimeListener
Implementors of this interface can set themselves as update listeners to a TimeAnimator instance to receive callbacks on every animation frame to receive the total time since the animator started and the delta time since the last frame. The first time the listener is called, deltaTime will be zero. The same is true for totalTime, unless the animator was set to a specific currentPlayTime prior to starting.
