Checking to see if player is next to a Brush

[??????]

I'm wanting to make a cover system for a gamemode and i need to check if a player is near a wall so that they can attach to it.Also how would i check for corners and edges.

Im guessing you will need to do traces, while not in cover do traces in a circle from the center of the player (waist height), looking for them to hit the world you would find your walls.

For the corners you do something similair, you make traces alongside the plane of the brush your 'attached too' (see HitNormal in that TraceRes wiki) in a 90' offset to the brush your leaning against

you would more than likely need to use if ply:IsInSphere() or something like that

UNTESTED but should work

function CheckForPlayers()
	local brush = ents.FindByName("MyLuaBrush") // it will have to be a func_brush in the map, and nto a normal brush, then name it MyLuaBrush
	local postentities = { }
	if #brush == 1 then
		local brush2 = brush[1]
		local players = ents.FindInSphere( brush2:GetPos() , 60 )
		for k,v in pairs( players ) do
			if players:IsPlayer then
				table.insert( postentities , v )
			end
		end
	end
end
