AABB issues

My AABB collision function doesn't work for negative coordinates for some reason. It does work with normal coordinates like 100, 100 but not with -100, 100. My whole game is literally built on a place been on negative coordinates so... I'm cooked:(

Can you send the function code?

Here's an example of AABB collision detection you can use in your game. To use it, use: if checkCollision(obj1,player) then//do somethink

Note that your objects must have a defined width and height for the function to use them in the calculation.

checkCollision = function(r1, r2)
  return r1.x - r1.width/2 < r2.x + r2.width/2 and
         r1.x + r1.width/2 > r2.x - r2.width/2 and
         r1.y - r1.height/2 < r2.y + r2.height/2 and
         r1.y + r1.height/2 > r2.y - r2.height/2
end

Thank you so much :)
