Constructor Detail

Animation.Implementation

public Animation.Implementation(GlContext ctx,
                                Scope parentScope)

Creates a new implementation.

Method Detail

start

public void start()

Starts the animation.

stop

public void stop()

Stops the animation.

stop

public void stop(float blendOut)

Stops the animation, blending out over the specified interval.

isPlaying

public boolean isPlaying()

Determines whether the animation is currently playing.

getPriority

public int getPriority()

Returns the priority of this animation.

tick

public boolean tick(float elapsed)

Updates this animation based on the elapsed time in seconds.

Returns:

true if the animation has completed.

hasCompleted

public boolean hasCompleted()

Checks whether this animation has completed.

updateTransforms

public void updateTransforms()

Updates the transforms directly from this animation.

blendTransforms

public void blendTransforms(int update)

Blends in the influence of this animation.

Parameters:

update - the current value of the update counter (used to determine which nodes have been touched on this update).

getScopeName

public String getScopeName()

Description copied from interface: Scope

Returns the name of this scope for purposes of qualification. Can return null if qualified symbols cannot specifically address this scope.

Specified by:

getScopeName in interface Scope

Overrides:

getScopeName in class SimpleScope

setConfig

protected void setConfig(AnimationConfig.Original config)

(Re)configures the implementation.

blendToWeight

protected void blendToWeight(float weight,
                             float interval)

Blends to a target weight over an interval specified in seconds.
