  • .lang files can be opened even in default notepad and easily edited
It is also recommended to check for using any other anticheats in order to avoid conflicts with them.

Installation:

  1. Download version of the anticheat which compatible with the version of your server
  2. Download the language file (.lang) in your preferred language
  3. Copy both files to a folder "/pawno/include" which is located in a folder with the server
  4. In gamemode and all filterscripts, after #include "a_samp" write the following: #include "nex-ac"
    Warning! If you use Streamer Plugin by Incognito, foreach, sscanf or Pawn.RakNet, include it before nex-ac!
    Also keep in mind that filterscript must have "#define FILTERSCRIPT" before including the anticheat
  5. Compile the modified scripts
