Question by stevesan · Feb 03, 2012 at 12:06 PM · 2dphysics

2D physics - Rigidbody.Constraints vs. ConfigurableJoint?

There seem to be two ways of restricting rigidbodies to 2D motion only: Using the Constraints (freeze Z position and freeze X, Y rotation), or attaching a ConfigurableJoint (like the Lerpz2D example does with its menu item). Is one better than the other for any reason? I'm currently using the constraints for simplicity, and it works for the most part, but I do need to take care as sometimes my character will "go behind" a wall. The solution to that is: Make the wall thicker in Z (my camera is orthographic so you don't see it). But, I was wondering if anyone else had other experiences or "gotchas" with this?
