yeah, I try to connect two nodes. One has several rigidbody2d and Pinjoint2d, and the other one has a kinematicbody2d. I put these two nodes into one scene, and add a pinjoint2d to the scene. I try to use the inspector to choose the nodea and nodeb, however, these two nodes are gray and not chosen able. Then, I try to use the script to connect them, but the result is they still go like two separate objects.
Is there any good solution for this problem?
and, thanks for the answer.
