AnimationTree¶

Inherits: Node < Object

A node to be used for advanced animation transitions in an AnimationPlayer.

Description¶

A node to be used for advanced animation transitions in an AnimationPlayer.

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.

NodePath	anim_player	`NodePath("")`
AnimationProcessCallback	process_callback	`1`
NodePath	root_motion_track	`NodePath("")`

void	rename_parameter ( String old_name, String new_name )

Enumerations¶

enum AnimationProcessCallback:

ANIMATION_PROCESS_PHYSICS = 0 --- The animations will progress during the physics frame (i.e. Node._physics_process).
ANIMATION_PROCESS_IDLE = 1 --- The animations will progress during the idle frame (i.e. Node._process).
ANIMATION_PROCESS_MANUAL = 2 --- The animations will only progress manually (see advance).

Property Descriptions¶

bool active

Default	`false`
Setter	set_active(value)
Getter	is_active()

If true, the AnimationTree will be processing.

NodePath advance_expression_base_node

Default	`NodePath(".")`
Setter	set_advance_expression_base_node(value)
Getter	get_advance_expression_base_node()

The path to the Node used to evaluate the AnimationNode Expression if one is not explicitly specified internally.

NodePath anim_player

Default	`NodePath("")`
Setter	set_animation_player(value)
Getter	get_animation_player()

The path to the AnimationPlayer used for animating.

AnimationProcessCallback process_callback

Default	`1`
Setter	set_process_callback(value)
Getter	get_process_callback()

The process mode of this AnimationTree. See AnimationProcessCallback for available modes.

NodePath root_motion_track

Default	`NodePath("")`
Setter	set_root_motion_track(value)
Getter	get_root_motion_track()

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 ":". For example, "character/skeleton:ankle" or "character/mesh:transform/local".

If the track has type Animation.TYPE_POSITION_3D, Animation.TYPE_ROTATION_3D or Animation.TYPE_SCALE_3D the transformation will be cancelled visually, and the animation will appear to stay in place. See also get_root_motion_transform and RootMotionView.

AnimationNode tree_root

Setter	set_tree_root(value)
Getter	get_tree_root()

The root animation node of this AnimationTree. See AnimationNode.

Method Descriptions¶

void advance ( float delta )

Manually advance the animations by the specified time (in seconds).

Transform3D get_root_motion_transform ( ) const

Retrieve the motion of the root_motion_track as a Transform3D that can be used elsewhere. If root_motion_track is not a path to a track of type Animation.TYPE_POSITION_3D, Animation.TYPE_SCALE_3D or Animation.TYPE_ROTATION_3D, returns an identity transformation. See also root_motion_track and RootMotionView.
