AnimationTreePlayer

Inherits: Node < Object

Deprecated. Animation player that uses a node graph for blending animations. Superseded by AnimationTree.

Description

Deprecated. A node graph tool for blending multiple animations bound to an AnimationPlayer. Especially useful for animating characters or other skeleton-based rigs. It can combine several animations to form a desired pose.

It takes Animations from an AnimationPlayer node and mixes them depending on the graph.

See AnimationTree for a more full-featured replacement of this node.

Property Descriptions

bool active

Default	false
Setter	set_active(value)

NodePath base_path

Default	NodePath("..")
Setter	set_base_path(value)
