A time-seeking animation node to be used with [AnimationTree].
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].

# Play child animation from the start.
animation_tree.set("parameters/Seek/seek_position", 0.0)
# Alternative syntax (same result as above).
animation_tree["parameters/Seek/seek_position"] = 0.0
# Play child animation from 12 second timestamp.
animation_tree.set("parameters/Seek/seek_position", 12.0)
# Alternative syntax (same result as above).
animation_tree["parameters/Seek/seek_position"] = 12.0
