    Try: Is Kinematic.

    It should be above fixed angle.

    I presume you are referring to colliders (you don't specify)? If you don't add a Rigidbody2D component then all colliders will be static and be at a fixed position.

    So you could use a HingeJoint2D for that with one end connected to your Rigidbody2d and the other to another Rigidbody2d or more likely don't specify one and it'll connect to the world thus making it rotate around that world position. You can also limit the arc it can rotate through.
