Need help with setting up 2D aiming.

[Leafdroid]

Currently its aiming depending on height of the cursor only, causing it to aim 90 degrees up no matter where on the top of the screen I have the cursor, I want it to aim towards the cursor instead. Any ideas on how to do this?

diry = 0
dir = 1
function GM:CreateMove( cmd )

	if dir == 1 then
	cmd:SetForwardMove( -cmd:GetSideMove() )
	cmd:SetForwardMove( cmd:GetSideMove() )
	cmd:SetViewAngles( Angle(diry, 0, 0) )
	cmd:SetSideMove( 0 )
	else
	cmd:SetForwardMove( cmd:GetSideMove() )
	cmd:SetForwardMove( -cmd:GetSideMove() )
	cmd:SetViewAngles( Angle(diry, 180, 0) )
	cmd:SetSideMove( 0 )
	end
	
end


usermessage.Hook( "ChangeOverview", ChangeOverview )

function GM:ShouldDrawLocalPlayer() return true end

function GM:CalcView( ply, origin, angles, fov )

	ply:ChatPrint(gui.MouseY()/ScrH()*180-ScrH()/12)

	diry = gui.MouseY()/ScrH()*180-ScrH()/12 -- The direction to aim, bottom of screen is 90 and top is -90.
	
	if gui.MousePos() > ScrW()/2 then
	dir = 1
	else
	dir = 0
	end
end
