distanceBetween seems to have an obvious bug... #22

Closed rozim closed 12 years ago

rozim commented 12 years ago

jaws.distanceBetween = function(object1, object2) { return Math.sqrt( Math.pow(object1.x-object2.x, 2) + Math.pow(object1.y, object2.y, 2) ) }

I think the last pow call needs to subtract the y's like this: Math.pow(object1.y - object2.y, 2)
