Retrieve the motion of the [member root_motion_track] as a [Transform3D] that can be used elsewhere. If [member root_motion_track] is not a path to a track of type [constant Animation.TYPE_POSITION_3D], [constant Animation.TYPE_SCALE_3D] or [constant Animation.TYPE_ROTATION_3D], returns an identity transformation. See also [member root_motion_track] and [RootMotionView].
Retrieve the motion of position with the [member root_motion_track] as a [Vector3] that can be used elsewhere.
If [member root_motion_track] is not a path to a track of type [constant Animation.TYPE_POSITION_3D], returns [code]Vector3(0, 0, 0)[/code].
See also [member root_motion_track] and [RootMotionView].
The most basic example is applying position to [CharacterBody3D]:
[codeblocks]
[gdscript]
var current_rotation: Quaternion
func _process(delta):
if Input.is_action_just_pressed("animate"):
current_rotation = get_quaternion()
state_machine.travel("Animate")
var velocity: Vector3 = current_rotation * animation_tree.get_root_motion_position() / delta
set_velocity(velocity)
move_and_slide()

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_POSITION_3D], [constant Animation.TYPE_ROTATION_3D] or [constant Animation.TYPE_SCALE_3D] the transformation will be cancelled visually, and the animation will appear to stay in place. See also [method get_root_motion_transform] and [RootMotionView].
