			local fx,fy,bx,by=obj:GetTexCoord();-- Only need front and back of one side (left is returned first)
			local a,dx,dy=0,fx-bx,by-fy;-- Y-Axis flipped for textures so Y values are swapped
			if obj==mmring then dx=-dx; end-- Compass Ring spins the opposite direction
			if dy==0 then-- Can't divide by zero
			a=dx<0 and math.pi or 0;-- Could either be one or the other in this condition
			else
			a=math.atan(dx/dy)+(dy<0 and math.pi or 0);-- atan() only returns half of the values we need, add PI when needed
			end

			return a;
			end
	end		end

			== Notes ==
			The old code posted here broke due to a change in the Minimap object. The player arrow shown is no longer a Model frame, it's a Texture now.
			Also note '''atan()''' is not the same function as '''math.atan''', the first returns in Degrees while the later returns in Radians.

			Due to the returns on '''math.atan()''', the range this function returns with is between -0.5PI and 1.5PI
