Juggler class - stagexl library

The Juggler controls the progress of your application by propagating the time passed between two render frames.

The RenderLoop and Stage class provide juggler instances which are driven by the browsers animation frames. You can also create your own Juggler instance and control the time by yourself. Because Juggler implements the Animatable interface it can be added to other Juggler instances too.

See also: Tween, Transition, DelayedCall

Examples:

var tween = new Tween(sprite, 1.0, Transition.easeIn);
tween.animate.x.to(1.0);
stage.juggler.add(tween);

// create a "gameJuggler" who controls all my animations.
var gameJuggler = new Juggler();
// start all animations controlled by "gameJuggler".
stage.juggler.add(gameJuggler);
// stop all animations controlled by "gameJuggler".
stage.juggler.remove(gameJuggler);

Methods

add(Animatable animatable) → void: Adds the animatable to this juggler who will take care that it is animated.
addChain(List<Animatable> animatables) → AnimationChain: This is a convenience method that creates an AnimatableChain and adds it to this juggler. See AnimatableChain for more details.
addGroup(List<Animatable> animatables) → AnimationGroup: This is a convenience method that creates an AnimatableGroup and adds it to this juggler. See AnimatableGroup for more details.
addTranslation(num startValue, num targetValue, num time, TransitionFunction transition, void onUpdate(num value)) → Translation: This is a convenience method that creates a Translation and adds it to this juggler. See Translation for more details.
addTween(TweenObject tweenObject, num time, [ TransitionFunction transition = Transition.linear ]) → Tween: This is a convenience method that creates a Tween and adds it to this juggler. See Tween for more details.
advanceTime(num time) → bool: This method is called by the Juggler with the time past since the last call.
clear() → void: Removes all Animatables from this juggler.
contains(Animatable animatable) → bool: Returns true if this juggler contains the specified animatable.
containsTweens(TweenObject tweenObject) → bool: Returns true if this juggler contains tweens for the specified tweenObject.
delay(num time) → Future: Returns a Future which completes after time seconds.
delayCall(Function action, num delay) → DelayedCall: This is a convenience method that creates a DelayedCall and adds it to this juggler. See DelayedCall for more details.
interval(num time) → Stream<int>: Returns a Stream of counter values which fires every time seconds.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.

inherited
remove(Animatable animatable) → void: Removes the specified animatable from this juggler.
removeTweens(TweenObject tweenObject) → void: Removes all tweens from the specified tweenObject.
timespan(num time) → Stream<num>: Returns a Stream of relative time which fires for time seconds.
toString() → String: Returns a string representation of this object.

inherited
translation(num startValue, num targetValue, num time, [ TransitionFunction transition = Transition.linear ]) → Stream<num>: Returns a Stream of translated values which fires for time seconds.
