# BoundingBox.lua

This script is used for Bounding Box Collision Detection. It will see if two rectangular objects over-lap. It returns true if there is a collision, and false otherwise.

This form of collision detection is not suited for games that have lots of circles and non-rectangular shapes, since the invisible space will be considered part of the collision rectangle. However, this should not be a problem for games such as Space Invaders clones.

    -- Collision detection function.-- Returns true if two boxes overlap, false if they don't-- x1,y1 are the left-top coords of the first box, while w1,h1 are its width and height-- x2,y2,w2 & h2 are the same, but for the second boxfunction CheckCollision(x1,y1,w1,h1, x2,y2,w2,h2)
      return x1 < x2+w2 and
             x2 < x1+w1 and
             y1 < y2+h2 and
             y2 < y1+h1
    end
