An [AnimationNodeOutput] node named [code]output[/code] is created by default. </description> <tutorials> <link title="Using AnimationTree">$DOCS_URL/tutorials/animation/animation_tree.html</link> </tutorials> <methods> <method name="add_node"> <return type="void" /> <param index="0" name="name" type="StringName" /> <param index="1" name="node" type="AnimationNode" /> <param index="2" name="position" type="Vector2" default="Vector2(0, 0)" /> <description> Adds an [AnimationNode] at the given [param position].
