Well, this is where my disclaimer comes in, some things will give you more problems and headaches than is worth teh hassle.
But here's what I would do:
A trigger_once under the player spawn, bear in mind it might be worth using a teleoprter to get the player into the map area, so that they can't run through other players trigger's and get weapons they shouldn't etc.
Set the triggers to target the multi_manager (you shldn't need multi-threaded) and have that target the game_playerequip, using too many playerequips can cause problems, so it may be worth experimenting with spreading the work out over two or four multi_managers, ie, different triggers target a different multi_manager, and they in turn target different game_playerequip's. But be warned, too many equip/trigger entities may cause errors (you getting the idea yet
)
Now just follow the tutorial to set up the gameplayer_equip and the multi_manager, don't go ticking anything taht isn't mentioned, as things liek Use Only will
not work unless the player knows they have to 'use' teh trigger, which they can't see, so don't.
Does that explain it any better?
Probably not but hey, any more q's just post here, I'll be sure to check back, also, trying to explain exactly what you did is no match for putting a map in teh Problems Vault.
