Class AnimationTimer

java.lang.Object

ch.swingfx.timer.AnimationTimer

public class AnimationTimer
extends Object

Class for simple animation. Example:

 AnimationTimer at = new AnimationTimer(FrameRate.FPS_25);
 at.setDuration(2500); // 2500 milliseconds
 at.setAnimationTarget(new AnimationTarget() {
                public void event(AnimationTimer timer, float fraction) {
                        // between begin and end.
                        // fraction represents the time passed (0f = 0%, 1f = 100%)
                }
                public void begin(AnimationTimer timer) {
                        // start of the animation                       
                }
                public void end(AnimationTimer timer) {
                        // end of the animation
                }
 });
 at.start();
