AnimComponent(system, entity) 

Create a new AnimComponent instance.

Parameters

system	AnimComponentSystem	The ComponentSystem that created this Component.
entity	Entity	The Entity that this Component is attached to.

booleanactivate 

If true the first animation will begin playing when the scene is loaded.

AnimComponentLayer, nullbaseLayer 

Returns the base layer of the state graph.

AnimComponentLayer[]layers 

Returns the animation layers available in this anim component.

booleannormalizeWeights 

If true the animation component will normalize the weights of its layers by their sum total.

booleanplayable 

Returns whether all component layers are currently playable.

booleanplaying 

Plays or pauses all animations in the component.

EntityrootBone 

The entity that this anim component should use as the root of the animation hierarchy.

numberspeed 

Speed multiplier for animation play back speed. 1.0 is playback at normal speed, 0.0 pauses the animation.

addLayer(name, [weight], [mask], [blendType]) 

Adds a new anim component layer to the anim component.

Parameters

name	string	The name of the layer to create.
weight	number	The blending weight of the layer. Defaults to 1.
mask	object[]	A list of paths to bones in the model which should be animated in this layer. If omitted the full model is used. Defaults to null.
blendType	string	Defines how properties animated by this layer blend with animations of those properties in previous layers. Defaults to pc.ANIM_LAYER_OVERWRITE.

Returns

AnimComponentLayer

The created anim component layer.

assignAnimation(nodePath, animTrack, [layerName], [speed], [loop]) 

Associates an animation with a state or blend tree node in the loaded state graph. If all states are linked and the AnimComponent#activate value was set to true then the component will begin playing. If no state graph is loaded, a default state graph will be created with a single state based on the provided nodePath parameter.

Parameters

nodePath	string	Either the state name or the path to a blend tree node that this animation should be associated with. Each section of a blend tree path is split using a period (.) therefore state names should not include this character (e.g "MyStateName" or "MyStateName.BlendTreeNode").
animTrack	object	The animation track that will be assigned to this state and played whenever this state is active.
layerName	string	The name of the anim component layer to update. If omitted the default layer is used. If no state graph has been previously loaded this parameter is ignored.
speed	number	Update the speed of the state you are assigning an animation to. Defaults to 1.
loop	boolean	Update the loop property of the state you are assigning an animation to. Defaults to true.
