Does Physics.Constraint.pointToPoint constrain relative rotation? #74

Closed MartinSStewart closed 4 years ago

MartinSStewart commented 4 years ago

Reading the documentation for Physics.Constraint.pointToPoint it isn't clear to me if it behaves like a weld joint or a ball joint. I'm guessing the two objects can freely rotate (unless they collide with eachother) but maybe the documentation could be explicit about this behavior?

@MartinSStewart your guess is correct, it only locks two points, but doesn't lock the rotation, so that two objects can freely rotate.
