Hey, I'm trying to create a SpringJoint system for my 2D UFO Grabber-style game in order to apply tension to the claw, and I'm currently trying to achieve this by moving the Spring location to redirect the direction that the claw is currently pointing towards.

Although i'm sure there's other ways I could achieve this, trying to animate the position doesn't work at all - the joint maintains the spring location set from the editor.
Is this a bug or a feature? Does anyone have any other potential solutions for achieving the same effect? (Im considering trying to apply two different springs to the same joint in different directions, that then alter their stiffness to get the claw to rotate).
