Host map or players map controlled?

[DECOY]

Being somewhat of a n00b, like many others I havent yet entirely figured out what elements of my host map that I change will be usuable by guest players, without them having to download a copy of my map.

E.G. I know if I change the ammo settings, everyone sees (and feels) the effect, and if I add additional zoom capabilities to a weapon, only I can use it. (Is this right?)
BUT, if I join someone elses game with my newly scoped weapons, I am still able to use the scope as a guest! (this was big eye opener) LOL!

I do realise that if I swap all the rocks and plants in Bloodgulch for trees to duck behind, only I see them. Everyone else thinks its lag!

Does anyone here definitely know / have some idea / a rough outline / got any fricking clue, of what can be changed in the host map that is then usuable by the guest player without downloading a copy of the hosts map.

Oh yeah, I do know its small stuff only, but its a great place to start off. A basic "Twenty - 10 second mods for HMT to get you started" sorta thing. Unlike trying to mod AI into Bloodgulch as your first project when you have no idea AT ALL whats involved, trying to open a .RAR file with explorer, asking the same $%$#@ questions (AGAIN), annoying everyone, being called a n00b, failing miserably and leaving Halomods to join the "halo PC is shit " crowd at Haloplanet, then eventually dying a lonely bitter old person who smells a bit like stale pee, and gets partially devoured by their 53 cats!!!

I mean, Come on! Do you want that on YOUR conscience?

Anyhoo....

The weapons changes I have in my mini-mod game alway work, dont cause lag, are just enough to force a change in gameplay and strategy. They generate a lot of interest from non-modding players. (So, NO its not a waste of time.)

Anyone?......

bascally the guests see NOTHING, but they will get laggy effects... lets put it simple lol

the host (you) and the joiner (someone else) have 2 differant maps, the joiners map doesnt want to believe the warthog is faster (just an example) but your map is forcing it move faster. but ya know what, the joiners map doesnt go without a fight cause laggy effects lol

basically the only things that i can think of at the moment where the joiners map WONT have the effect is skins, models, ay rebuilt map (will cause them an exception error) zoom, or scnenery swapping

this is where a lot of people end up cheating in the game. Many people can make the ground in some levels transparent, and can see what is happening all the way across the level! EVEN IF YOU'RE A GUEST!!!!

Ya, its cheating, and wrong!

Yeah I have had the unfortunate experience of being on the recieving end of a "guest" who joined my game equipped with a combination of XXX XXXX XXXX and XXXXX XXXX on XXXXXX.

EDIT:- (Suddenly thought - not a good idea to give specifics on cheats!!)

Totally killed the balance of play, and he/she is one of the few people I have on a Permanent ban, never to be lifted. I havent seen their player name online for a while, so I assume that word spread and they had to change it.

I knew that vehicle speed mods caused lag, but how come minor ammo mods dont? Is it just because they (mostly) dont have an physical object to track across the map?

Obviously I dont include ammo mods like swapping rockets for tank shells! That just confuses the joiner, he sees the rocket leave the launcher and then is immediately killed by an unseen force, and then the rocket reaches his already dead player several seconds later.
