    Snippet: Get angle from two vectors

    Hi folks,

    here is a little function that determines the angle of two given vectors in degrees.
    vecAngle = function(startX, startY, targetX, targetY)  
	local xdiff = targetX - startX
	local ydiff = targetY - startY
    	local ang = math.atan2( ydiff, xdiff )
	ang = math.deg(ang) + 90.0
	if ang < 0 then 
		ang = 360.0 + ang
	end
	return ang
end
