How do I make this code for props getting cleared when no players are on

[ryanm2711]

Hey, I'm making an addon but I'm having trouble with this function. It has no errors but it doesn't work.

function clearprops()
    if player.GetAll() == nil then
        RunConsoleCommand( "ulx", "cleanup" )
        print("Cleaning up props because no players are on.")
    end
end

Thanks for the fast reply!

hook.Add("PlayerDisconnected","clear props when empty",function(ply)--called when a player leaves the game
timer.Simple(0.1,function()--make sure the player has disappeared before we execute our function
if player.GetCount()==0 then--player.GetCount returns how many player entities there are, it equals 0 if the server is empty
game.CleanUpMap()--ulx cleanup uses this function internally
print("Cleaning up props because no players are on.")
end
end)
end)

Thanks, I was using ulx command instead of game.CleanUpMap()
