You'll need math.atan2. If you want more specific help, please read the rules and upload a .love of your game.

Something like this gives an angle in Radians.

Code: Select all

-- Returns the angle between two points.
function utils.angle(x1,y1, x2,y2)
	local angle = math.atan2(y2-y1, x2-x1)
	if angle < 0 then angle = angle + math.pi * 2 end
	return angle
end

This was already featured on the wiki, as a snippet, without the angle correction, though.
