Note: When linked with an [AnimationPlayer], several properties and methods of the corresponding [AnimationPlayer] will not function as expected. Playback and transitions should be handled using only the [AnimationTree] and its constituent [AnimationNode](s). The [AnimationPlayer] node should be used solely for adding, deleting, and editing animations.

The path to the Animation track used for root motion. Paths must be valid scene-tree paths to a node, and must be specified starting from the parent node of the node that will reproduce the animation. To specify a track that controls properties or bones, append its name after the path, separated by [code]":"[/code]. For example, [code]"character/skeleton:ankle"[/code] or [code]"character/mesh:transform/local"[/code].
If the track has type [constant Animation.TYPE_TRANSFORM], the transformation will be cancelled visually, and the animation will appear to stay in place.

<brief_description>
Editor-only helper for setting up root motion in [AnimationTree].
</brief_description>
<description>
[i]Root motion[/i] refers to an animation technique where a mesh's skeleton is used to give impulse to a character. When working with 3D animations, a popular technique is for animators to use the root skeleton bone to give motion to the rest of the skeleton. This allows animating characters in a way where steps actually match the floor below. It also allows precise interaction with objects during cinematics. See also [AnimationTree].
[b]Note:[/b] [RootMotionView] is only visible in the editor. It will be hidden automatically in the running project, and will also be converted to a plain [Node] in the running project. This means a script attached to a [RootMotionView] node [i]must[/i] have [code]extends Node[/code] instead of [code]extends RootMotionView[/code]. Additionally, it must not be a [code]@tool[/code] script.
