-- This is the one that just does the job:

local function deathChat( ply, txt, teamChat, isDead)
	if ply:IsPlayer() and isDead == true then
    return(true)
    end
end

hook.Add ("OnPlayerChat", "jameZtheDeadCantTalk", deathChat)

-- This is the one that I'm trying to add to:

local function deathChat( ply, txt, teamChat, isDead)
	if ply:IsPlayer() and isDead == true then
    return(true)

    end

end

local function wtf ()
	PrintMessage( HUD_PRINTTALK, "Shhh Now! The Dead Can't Talk" )
end

hook.Add ("OnPlayerChat", "jameZtheDeadCantTalk", deathChat)
hook.Add ("OnPlayerChat", "jameZtheDeadCantTalk", wtf)

-- This shows that the PrintMessage function actually works (on a separate hook):

local function wtf ()
	PrintMessage( HUD_PRINTTALK, "Shhh Now! The Dead Can't Talk" )
end

hook.Add ("OnPlayerHitGround", "sdsd", wtf)
