Simple physics detection library I made. It is composed of polygons and detects if the lines of two polygons intersect. That means if one polygon is fully inside another then it returns false. This can be useful for things like making sure they player is staying in bounds. Polygons can be made with ...

Thanks pgimeno, that works perfectly!

In my game I have a menu with a lot of buttons, each with a number. That number is associated with a function to call when the button is pressed. Instead of having a super long "if-else-chain" to call the right function, I wanted to make a for loop. I can't figure out how to call a functio...

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)

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.

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 want to make my track collide with my car, but only in the way I choose to. I'm using the isTouching functions to check when I hit the edge of the track so I can then put it at the start of the track. The current problem is the track moves slightly every time I crash into it because the physics en...
