Another way of detecting collisions. This type works perfectly with circles. It checks if the distance of one object to the other is less than the sum of their radii(plural of radius.)
Variable Definitions : ax, ay = circleA's coordinates; bx, by = circleB's coordinates; ar, br = circleA's and circleB's radii, respectively
function checkCircularCollision(ax, ay, bx, by, ar, br)
local dx = bx - ax
local dy = by - ay
local dist = math.sqrt(dx * dx + dy * dy)
return dist < ar + br
end
