A node to be used for advanced animation transitions in an [AnimationPlayer]. A node to be used for advanced animation transitions in an [AnimationPlayer]. [b]Note:[/b] 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. $DOCS_URL/tutorials/animation/animation_tree.html https://godotengine.org/asset-library/asset/678 Manually advance the animations by the specified time (in seconds). 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() [/gdscript] [/codeblocks] Retrieve the motion of rotation with the [member root_motion_track] as a [Quaternion] that can be used elsewhere. If [member root_motion_track] is not a path to a track of type [constant Animation.TYPE_ROTATION_3D], returns [code]Quaternion(0, 0, 0, 1)[/code]. See also [member root_motion_track] and [RootMotionView]. The most basic example is applying rotation to [CharacterBody3D]: [codeblocks] [gdscript] func _process(delta): if Input.is_action_just_pressed("animate"): state_machine.travel("Animate") set_quaternion(get_quaternion() * animation_tree.get_root_motion_rotation()) [/gdscript] [/codeblocks] Retrieve the motion of scale 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_SCALE_3D], returns [code]Vector3(0, 0, 0)[/code]. See also [member root_motion_track] and [RootMotionView]. The most basic example is applying scale to [CharacterBody3D]: [codeblocks] [gdscript] var current_scale: Vector3 = Vector3(1, 1, 1) var scale_accum: Vector3 = Vector3(1, 1, 1) func _process(delta): if Input.is_action_just_pressed("animate"): current_scale = get_scale() scale_accum = Vector3(1, 1, 1) state_machine.travel("Animate") scale_accum += animation_tree.get_root_motion_scale() set_scale(current_scale * scale_accum) [/gdscript] [/codeblocks] If [code]true[/code], the [AnimationTree] will be processing. The path to the [Node] used to evaluate the AnimationNode [Expression] if one is not explicitly specified internally. The path to the [AnimationPlayer] used for animating. The process mode of this [AnimationTree]. See [enum AnimationProcessCallback] for available modes. 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_position], [method get_root_motion_rotation], [method get_root_motion_scale] and [RootMotionView]. The root animation node of this [AnimationTree]. See [AnimationNode]. Emitted when the [member anim_player] is changed. The animations will progress during the physics frame (i.e. [method Node._physics_process]). The animations will progress during the idle frame (i.e. [method Node._process]). The animations will only progress manually (see [method advance]).
