    Snippet: Get the distance of 2 vectors/sprites

    Hi folks,

    this snipped will calculate the distance in pixel of two given vector coordinates:
    local vecDist = function(x, y, tx, ty)
	--Calculate the distance between 2 vectors
	local xdiff = x - tx
	local ydiff = y - ty
	local dist = (xdiff*xdiff+ydiff*ydiff)^0.5
	return dist
end

      And here a function to calculate the distance between two sprites:
      local getSpriteDist = function(source, target)
	--Calculate the distance between 2 vectors
	local xdiff = source:getX() - target:getX()
	local ydiff = source:getY() - target:getY()
	local dist = (xdiff*xdiff+ydiff*ydiff)^0.5
	return dist
end
