(Thirdperson) Checking if a player is up against a wall(anti-clipping checks)

[MaximLaHaxim]

	local UseTP = false
	
	local function ToggleTP( len )
		UseTP = !UseTP
	end
	net.Receive( "CL_EnableThirdPerson", ToggleTP )

	local view = {origin=vector_origin,angles=angle_zero,fov=0}
	local function MyCalcView( playr, positn, angles, fov )
		view.origin = positn
		view.angles = angles
		view.fov = fov
		
		if UseTP then
			view.origin = positn-(angles:Forward()*85)
		end
	
		return view
	end
	hook.Add( "CalcView", "MyCalcing", MyCalcView )

Hey there! If you can't tell by the code, I'm making a simple thirdperson system. Does anyone know how I could check if the player is up against a wall? As this is for TTT, I want to prevent possible ghosting by people looking through walls when they get up against them in the TP mode. Thanks!
