I figured it out!! But you won't be needing joints. You need to push & rotate non-physically. Turn saw physics off. Then attach global linear event & local or global rotate event (delta looks freaky!). It works. The catch? You can only move the saw horizontally & vertically. But hey! That's still pretty useful. I might use this saw in my next level! EDIT: Already figured out... derp. Though I think this solution is easier than the one above!
I have a question. When the saw turns to the opposite direction, is it smooth? I need an alternative for $@?&"s. EDIT: I figured out how to make the saw go in a different direction! Just rotate the saw how you want it
