I want to know if arbitrary two colliders will collide or not. So I called Physics2D.GetIgnoreCollision(collider1, collider2) to check it. But it seems not to work. Physics2D.GetIgnoreCollision(collider1, collider2) returns False even if they are connected with any joint2D and they do not enable collision. I wanna know is there any other way to check if arbitrary colliders(or ridibodies) will collide or not? Because it's hard to check there is any joint connected on this rigidbody.
