	<brief_description>
		State machine for control of animations.
	</brief_description>
	<description>
		Contains multiple nodes representing animation states, connected in a graph. Node transitions can be configured to happen automatically or via code, using a shortest-path algorithm. Retrieve the [AnimationNodeStateMachinePlayback] object from the [AnimationTree] node to control it programmatically.
		[b]Example:[/b]
		[codeblocks]
		[gdscript]
		var state_machine = $AnimationTree.get("parameters/playback")
		state_machine.travel("some_state")
		[/gdscript]
		[csharp]
		var stateMachine = GetNode&lt;AnimationTree&gt;("AnimationTree").Get("parameters/playback") as AnimationNodeStateMachinePlayback;
		stateMachine.Travel("some_state");
		[/csharp]
		[/codeblocks]
