Not letting box2d physics resolve

[TheFriendlyFoe]

I have a game, but I don't want box2d to resolve any of the collisions, I want to code my own resolutions to collisions. Is there a way I can turn off the physics between fixtures while still being able to get if 2 fixtures are touching?

I think bump.lua might suit your needs better.

Thanks for the suggestion but the problem is I have a ton of not axis-aligned rectangles. I'm making a racing game and the tracks are make with many rectangles on the outside.

Ok I did some research and I think I found the solution: setting the fixtures to sensors. This is the simple answer for anyone else who needs it. You can do it by doing something like this:
fixture:setSensor(true)
