You can use this node to get the information which part of an Animation State is played back. The complete length of all animations referenced in an Animation State is mapped to a range from 0 to 1.
If an Animation State references animations of 4 seconds length, and 2 seconds are already played back, then this node will return a value of 0.5. When an Animation State is played back in a loop, then a value of 1 is added each time a loop is completed. Loop position is updated at the Update Animation State Transition node or you can set directly using the Set Animation State Loop node.
This node is also useful to blend animations together depending on the point in time the Animation State is played back.
