+		This node can be used to cause a seek command to happen to any sub-children of the animation graph. Use this node type to play an [Animation] from the start or a certain playback position inside the [AnimationNodeBlendTree]. After setting the time and changing the animation playback, the seek node automatically goes into sleep mode on the next process frame by setting its [code]seek_position[/code] value to [code]-1.0[/code].
