I am currently working on a unity project and I have a stickman built by Hinge Joints but when I animate his legs and activate the animation, the legs stays at the same position and the rest of the body is moving forward.
How can I animate the legs without freezing it's position?
This worked for me:
Anchor and Axis should be correct, if it works with a motor. For testing, deactivate "Use Spring", "Use Limits" and "Use Motor". If it still doesn't move, you should have a look at the rigidbody. "Is Kinematic" should be deactivated as well.
From here
