This should be 99% self-explanatory, this is a table of legal mods per vehicle & a way to block all invalid (crashy) mods from being applied.

There are assholes running bots which connect to a server, teleport in a car around and send crashing mod info to crash players en-masse, this should enable you to 100% protect yourself against this threat.

I just took this out of my gamemode quickly so it's not a filterscript, but the first person to release a filterscript = gratuitous turtle reward?

[Face9000]

Awesome.

[Hoborific]

Perfect, thank you.

[Sufyan]

Great Thanks for this

[Nicholas.]

Nice.

[king_hual]

It's nice. Even though I wouldn't call this a tutorial since it's just a snippet of code.

Thanks for the tips.

banaplayer(ANTICHEAT_ID, PlayerID, "Fuck you and your mods!");

Nice job

[BMUK]

lol @ .."Fuck you and your mods!");

[toi]

Thanks but where do I put all that data, I want to say under which heading?
