Re: Nex-AC - Anticheat system - diclofoss - 02.01.2017

Hello!
After long investigation I found how to reconcile shoebill and nex-ac
I found in your code following:

PHP код:



ac_fpublic ac_AntiCheatGetAnimationIndex(playerid) return ACInfo[playerid][acAnim];

ac_fpublic ac_AntiCheatGetDialog(playerid) return ACInfo[playerid][acDialog];

ac_fpublic ac_AntiCheatGetMoney(playerid) return ACInfo[playerid][acMoney];

ac_fpublic ac_AntiCheatGetClass(playerid) return ACInfo[playerid][acClassid];

ac_fpublic ac_AntiCheatGetEnterVehicle(playerid) return ACInfo[playerid][acEnterVeh];

If your code can get all variables via API I can implement shoebill function to fill your parameters.
In other words, every time when you are going to hook any event you should take data not from enum directly but from function (you have almost done this as far as I see). And add this data getters into a separate file, so I can overwrite it.

Re: Nex-AC - Anticheat system - diclofoss - 03.01.2017

There is an issue with textdraw in the latest version of anti-cheat.
I can't select my menu

Re: Nex-AC - Anticheat system - diclofoss - 03.01.2017

****** by SlonoBoyko 24.11.2016 - this cheat is transparent for Nex-AC versions: 1.16-1.9
(tried pure nex-ac without any gamemode)
UPD: sorry everything with this cheat is ok

So I checked it with my dialogs that use textdraws (video)
As you can see it works. At the end I was flooding in order to show that anticheat is connected and all anti-cheat codes are enabled

Re: Nex-AC - Anticheat system - diclofoss - 03.01.2017

Finally I found a workaround for shoebill project
I need to override OnCheadDetected variable and controll everything on Shoebill side.
Hope somebody helps this.

For now I find good solution for me. I use only physical calculation on NEX-AC side, and controll all flags on the shoebill side. So problem is closed. Sorry for disturbing and thank you for your support

Maybe the root cause the same: I create my textdraw directly with GDK

Re: Nex-AC - Anticheat system - diclofoss - 03.01.2017

Just want to say again than you so much for your job.
I wish you all the best.

PHP код:



public OnCheatDetected(playerid, ip_address[], type, code)

 Called when the tripped one of the anti-cheats

 playerid - ID of the cheater

 ip_address[] - IP-address of the cheater

 type - Type of cheating (when 0 it returns the ID, when 1 - IP)

 code - Code (ID) of the anti-cheat

how to use these only for money hack ?
plz show me an example ??

SO we can Add banningSystem under this ?

Код:

GivePlayerMoney(playerid, a);
return 1; //We don't need another punishment

No, would be better to just have serverside money (stored in player statistics).

Re: Nex-AC - Anticheat system - Juonis - 05.01.2017

When PLAYER1 is spectating PLAYER2 and PLAYER2 gets kicked for whatever reason (in this case hacks) then PLAYER1 will be kicked out of the server (this line reacts even anticheats are off);

Quote:

default: //All others cheats
{
static strtmp[sizeof KICK_MSG];
format(strtmp, sizeof strtmp, KICK_MSG, code); //Another way to say goodbye
SendClientMessage(playerid, -1, strtmp);
}

How can I fix that?

If you are using in your gm public OnCheatDetected, you can add to switch the following case:

PHP код:



case 21: return 1; //Unless, of course, triggered exactly code 21?

Although better if you describe your problem specifically. For example, what writes to the console at the time of kick?

Thanks this helped. Also if player takes guns from pickup in server he/she gets kicked, can I turn off all the 'anticheats' for specific period of time, what should I do to prevent kicking player for taking guns from pickup? Players for taking guns using a pickup are kicked with "add ammo" anticheat.
Also innocent players are kicked for NOP even though they are not cheating; when player enter a vehicle and then leaves (not always, sometimes).

Also if you are using shotgun and switch to AK or M4 and shoot (with a short period of time) you will be punished for rapid.

So, how do I give weapons in order not to be kicked? I am using GetPlayerWeaponEx now.

You also can use "EnableAntiCheatForPlayer" function to enable or disable specifically anti-cheat code for player, just use it when you want to disable it and after some time enable it again, if you want.
As about rapid fire, I tested it, but unfortunately didn't saw anything

New Version v1.9.17

Changes:
* Added check for the validity of the pickup when a player picks it up
* Increased the minimum distance of detection AirBreak onfoot

Fixes:
* Fixed anti-CJ run with a kick for landing on parachute (holding 'S' key)
* Fixed anti-FlyHack with parachutist animation

Re: Nex-AC - Anticheat system - renatog - 20.01.2017

Why don't you use Git properly? You create a ton of folders for each version of the include. You are using GitHub, but you aren't using Git version control, that does exactly what you want, but better in visual and organization. We can't see exaclty what you modified in each version, not without wasting time checking every file or putting them in an online text diff (which can't detect all diffs). You can use "release" feature to manage releases.
And... look at this:

We have to find the latest version.

Don't get me wrong, I'm just trying to help you help the users.
This is a huge anti-cheater lib, thanks for share. Maybe I use it.
