 # Physics Animation Layout
 
 ## Overview
-**PhysicsAnimationLayout** works with an implementation of **PhysicsAnimationController** to construct and maintain physics animations for each of its child views. During the initial construction of the animations, the layout queries the controller for configuration settings such as which properties to animate, which animations to chain together, and what stiffness or bounciness to use. Once the animations are built to the controller’s specifications, the controller can then ask the layout to start, stop and manipulate them arbitrarily to achieve any desired animation effect. The controller is notified whenever children are added or removed from the layout, so that it can animate their entrance or exit, respectively.

During the initial construction of the animations, the layout queries the controller for basic configuration settings such as which properties to animate, which animations to chain together, and the default physics parameters to use.
+
+Once the animations are built, the controller can access **PhysicsPropertyAnimator** instances to run them. The animator behaves similarly to the familiar `ViewPropertyAnimator`, with the ability to animate `alpha`, `translation`, and `scale` values. It also supports additional functionality such as `followAnimatedTargetAlongPath` for more advanced motion.

 An example usage is Bubbles, which uses a PhysicsAnimationLayout for its stack of bubbles. Bubbles has controller subclasses including StackAnimationController and ExpansionAnimationController. StackAnimationController tells the layout to configure the translation animations to be chained (for the ‘following’ drag effect), and has methods such as ```moveStack(x, y)``` to animate the stack to a given point. ExpansionAnimationController asks for no animations to be chained, and exposes methods like ```expandStack()``` and ```collapseStack()```, which animate the bubbles to positions along the bottom of the screen.

 ### Animation Control Methods
 Once the layout has used the controller’s configuration properties to build the animations, the controller can use them to actually run animations. This is done for two reasons - reacting to a view being added or removed, or responding to another class (such as a touch handler or broadcast receiver) requesting an animation. ```onChildAdded```, ```onChildRemoved```, and ```setChildVisibility``` are called automatically by the layout, giving the controller the opportunity to animate the child in/out/visible/gone. Custom methods are called by anyone with access to the controller instance to do things like expand, collapse, or move the child views.
 
-In either case, the controller can use `super.animationForChild` to retrieve a `PhysicsPropertyAnimator` instance. This object behaves similarly to the `ViewPropertyAnimator` object you would receive from `View.animate()`.

+- `position(float, float, Runnable…)`, which starts translationX and translationY animations, and calls the provided callbacks only when both animations have completed.
+- `followAnimatedTargetAlongPath(Path, int, TimeInterpolator)`, which animates a ‘target’ point along the given path using a traditional Animator. As the target moves, the translationX/Y physics animations are updated to follow the target, similarly to how they might follow a touch event location. This results in the view roughly following the path, but with natural motion that takes momentum into account. For example, if a path makes a 90 degree turn to the right, the physics animations will cause the view to curve naturally towards the new trajectory.

 It also provides the following configuration methods:
 - `withStartDelay(int)`, for starting the animation after a given delay.
 - `withStartVelocity(float)`, for starting the animation with the given start velocity.

 - Often, animations will set starting values for properties before the animation begins. Property methods like `translationX` have an overloaded variant: `translationX(from, to)`. When `start()` is called, the animation will set the view's translationX property to `from` before beginning the animation to `to`.
 - We may want to use different end actions for each property. For example, if we're animating a view to the bottom of the screen, and also fading it out, we might want to perform an action as soon as the fade out is complete. We can use `alpha(to, endAction)`, which will call endAction as soon as the alpha animation is finished. A special case is `position(x, y, endAction)`, where the endAction is called when both translationX and translationY animations have completed.

-`PhysicsAnimationController` also provides `animationsForChildrenFromIndex(int, ChildAnimationConfigurator)`.

The `ChildAnimationConfigurator` is called with a `PhysicsPropertyAnimator` for each child, where calls to methods like `translationX` and `withStartVelocity` can be made. `animationsForChildrenFromIndex` returns a `MultiAnimationStarter` with a single method, `startAll(endAction)`, which starts all of the animations and calls the end action when they have all completed.

 ## PhysicsAnimationLayout
 The layout itself is a FrameLayout descendant with a few extra methods:
 
-```setController(PhysicsAnimationController controller)```
-Attaches the layout to the controller, so that the controller can access the layout’s protected methods. It also constructs or reconfigures the physics animations according to the new controller’s configuration methods.
+```setActiveController(PhysicsAnimationController controller)```
+Sets the given controller as the active controller for the layout. This causes the layout to construct or reconfigure the physics animations according to the new controller’s configuration methods, and halt any in-progress animations.
 
-```setEndListenerForProperty(ViewProperty property, AnimationEndListener endListener)```
-Sets an end listener that is called when all animations on the given property have ended.
-
-```setMaxRenderedChildren(int max)```
-Child views beyond this limit will be set to GONE, and won't be animated, for performance reasons. Defaults to **5**.
-
-It has one protected method, ```animateValueForChildAtIndex(ViewProperty property, int index, float value)```, which is visible to PhysicsAnimationController descendants. This method dispatches the given value to the appropriate animation.

+Only the currently active controller is allowed to start animations. If a different controller is set as the active controller, the previous controller will no longer be able to start animations. Attempts to do so will have no effect. This is to ensure that multiple controllers aren’t updating animations at the same time, which can cause undefined behavior.
