AnimationController.setPlaySpeed(speed) Sets the speed of the animation playback relative to the default speed but doesn't start playback. Note: To play an animation in reverse, use setPlayForward(false) instead of setPlaySpeed(-1) speed < 1: Animation is played slower than it's default speed speed = 1: Animation is played at it's default speed (default) speed > 1: Animation is played faster than it's default speed AnimationController.setSmoothness(smooth) Sets how smoothly the animation will transition from being stopped (at the beginning) to full speed (middle) to stopped again (at the end). Note: any value 0 and above is valid, but anything above 10 is fairly similar smooth = 0: No smoothing (linear speed) smooth = 1: Partial smoothing(half linear, half cosine wave) (default) smooth = 10: Full smoothing (animation speed follows cosine wave) AnimationController.setPlayRange(starttime, endtime) Sets the section of the animation to play. If your animation is 10 seconds long but you only want to play the last 4 seconds, call setPlayRange(6, 10). Note: These numbers always represent time in the original animation's reference frame. i.e. You don't have to change the playRange after changing playForward or playSpeed. Endtime should always be greater than Starttime, even if playForward is set to false. starttime: Determines the where the animation will start playing endtime: Determines the where the animation will stop playing Note: There are get functions for most of the above parameters, i.e. getPlaySpeed(), getSmoothness(), getPingPong(), ...
