Snippet: Collision check Box2Box

Hi there,
here is a function, which will check a collision between 2 sprites by checking if the boundries overlap.
You might want to make the math.abs call local. Same goes for the width and height. If you don't need to calculate them dynamically, then store these values when you create the sprite in them and use these user properties.
Cheers
Michael

collCheck_Box2B = function( source, target ) local rw = source:getWidth()/2.0 + target:getWidth()/2.0 local rh = source:getHeight()/2.0 + target:getHeight()/2.0 if math.abs(source:getY() - target:getY()) < rh then if math.abs(source:getX() - target:getX() ) < rw then return true end end return false end |
Cheers
Michael
