All decision should pass by an callback an we choose what we want to make

Add an callback for that is my sugestion.

i did a benchmark with this Slice benchmark function

Bench for ac_OnPlayerUpdate: executes, by average, 43.92 times/ms.

43 times in ms with 1 player and i have 100 pb that will probably make my server laggy.

I wouldn't say that will be too much an issue the main issues I mentioned here.

I would still maintain tossing all this code into a single include is a monumental design flaw for an anti-cheat system there should be an include for EACH cheat. The design of this system is completely non-extensible and has some serious array indexing flaws. In my opinion this is an example of how NOT to design an anti-cheat system.

Look at these code examples for the ridiculousness of some of the design choices.

Код:

if(ac_i < AntiCheatInfo[playerid][acCall][13] + ac_Mtfc[13][0]) ac_FloodDetect(playerid, 13);
                else if(ac_i < AntiCheatInfo[playerid][acCall][27] + ac_Mtfc[27][0]) ac_FloodDetect(playerid, 27);
                else AntiCheatInfo[playerid][acFloodCount][13] = AntiCheatInfo[playerid][acFloodCount][27] = 0;

Код:

                AntiCheatInfo[AntiCheatVehInfo[vehicleid][acDriver]][acNOPCount][4] = 0;
                AntiCheatInfo[AntiCheatVehInfo[vehicleid][acDriver]][acSetVehHealth] = health;
                AntiCheatInfo[AntiCheatVehInfo[vehicleid][acDriver]][acGtc][4] = GetTickCount();

I am really left shaking my head at this code as it is completely and utterly absurd.

This I agree with you I hope in futur he start to split his script and use the methods you said.

I guess you can use the public OnPlayerWeaponShot (or something like that), and check if the weapon's ammo became less than it was before. If the ammo did not become less after the shot, then they're probably doing infi ammo.
Never tried it like this but when doing it the right way it should work fine.

Re: Nex-AC - Anticheat system - Scriptery - 03.09.2015

all in one good anti cheat!

Is this safe to use on a big server?

I would agree, you can't just take a system like this toss it into your server and expect it to magically work without issues.

Maybe it really looks ugly, but it works)
However, I don't think the style of my code is good, but I don't have time to make it better.

You probably need to enable detection on player's connect, and not in gamemodeinit

Re: Nex-AC - Anticheat system - Irenijus - 06.09.2015

Can you show please ??

Re: Nex-AC - Anticheat system - Irenijus - 06.09.2015

I think this a/c is bugged.............

Well, you probably didn't load include's required plugins, try loading streamer, sscanf and whirlpool plugins

Strange its working perfectly with that plugins I said above, this anti-cheat is very good but it has a lot false detections
