A generic animation transition node for [AnimationTree]. Simple state machine for cases which don't require a more advanced [AnimationNodeStateMachine]. Animations can be connected to the inputs and transition times can be specified. $DOCS_URL/tutorials/animation/animation_tree.html https://godotengine.org/asset-library/asset/125 https://godotengine.org/asset-library/asset/678 Returns [code]true[/code] if auto-advance is enabled for the given [param input] index. Enables or disables auto-advance for the given [param input] index. If enabled, state changes to the next input after playing the animation once. If enabled for the last input state, it loops to the first. The number of enabled input ports for this node. If [code]true[/code], the destination animation is played back from the beginning when switched. Determines how cross-fading between animations is eased. If empty, the transition will be linear. Cross-fading time (in seconds) between each animation connected to the inputs.
