ModelAnimator

public class ModelAnimator

An animation of a model bound to a ModelRenderable.

Controls progress and state of the animation, updates the attached ModelRenderable and sends notifications via Animator.AnimatorListener and Animator.AnimatorPauseListener if needed.

ModelAnimator is created using a AnimationData as an animation source and a ModelRenderable as a target.

ModelAnimator only keeps WeakReferences to the source and target of the animation. To add a strong reference, attach a ModelRenderable to a Node.

TimeInterpolator may be used to change the timing of the animation via setInterpolator(TimeInterpolator), but only monotonically increasing TimeInterpolators are supported. The animation can not be made to play in reverse.

ModelAnimator must be used on the main thread. Animator.AnimatorListener and Animator.AnimatorPauseListener will be called on the main thread.

Constants

int INFINITE Used with the setRepeatCount(int) property to repeat the ModelAnimator indefinitely.

Constants

public static final int INFINITE

Used with the setRepeatCount(int) property to repeat the ModelAnimator indefinitely.

Constant Value: -1

Public Constructors

public ModelAnimator (AnimationData source, ModelRenderable target)

Constructs a new ModelAnimator.

Parameters
source Defines how the target will change during the animation.
target Determines which ModelRenderable will be modified during animation. Target may be null, but

Public Methods

public String getName ()

Returns the name of the AnimationData. This may return "" if there is no connected AnimationData or it has been garbage collected.

public int getRepeatCount ()

Returns the number of times the ModelAnimator should repeat, or INFINITE. The default value is 0.

public ModelRenderable getTarget ()

Gets the ModelRenderable this ModelAnimator applies to or null if there is none.

public ModelAnimator setDuration (long duration)

Sets the duration of the ModelAnimator.

Parameters
duration
Throws
IllegalArgumentException} for negative durations and IllegalStateException if the ModelAnimator has already started.

public void setInterpolator (TimeInterpolator value)

Sets the time interpolator used in calculating the elapsed fraction of the ModelAnimator.

Only monotonically increasing TimeInterpolators are supported. The default value is LinearInterpolator by default.

Parameters
value the interpolator to be used by this ModelAnimator

public void setRepeatCount (int repeatCount)

Sets how many times the ModelAnimator should be repeated. If repeatCount is 0, the ModelAnimator plays once. The initial setting for repeatCount is 0.

Parameters
repeatCount the number of times the ModelAnimator should be repeated or INFINITE.

public void setTarget (ModelRenderable target)

Sets the ModelRenderable this ModelAnimator applies to.

Parameters
target The object being animated. This value may be null.

public void start ()

Starts this ModelAnimator at the beginning.

Throws
IllegalStateException if two ModelAnimators are started on the same ModelRenderable at the same time or if isStarted() is already true.
