What kind of anti-cheat?

[Ozzapoo]

The problem with posting anti-cheats publicly is that they are quickly destroyed, therefore rendering the protection useless.

[UndeadxAssassin]

It's like Ozzapoo said, it'll be easier to break if it's public. But there are some easy-to-code anticheats. Basically, just have it search for when a player types something (like -gold or -lumber) and then either have the game remove all of their gold/lumber or reset it to what it was before. That's usually what I see in anticheats. They have something like

Code: Select all

call TriggerRegisterPlayerChatEvent(xI,Player(1),"-gold ",false)

for every player, and at the end, it'll have something like

Code: Select all

call TriggerAddAction(xI,function uq)

And function uq (in this case) would save the gold they have now and then revert it to this after the gold has been added from the cheats.

Another protection I've seen against JJ's cheatpack is to just have functions named the same as JJ's functions (like Explodey, CheatUse, Yellowy, etcc..). It screws it up because then you'd have to rename the functions and other stuff.

Lastly, adding JJ's cheatpack for single player use only screwed lots of people over. There was a Heaven vs. Hell map that had JJ's CP for single player use and it would make the game unable to be found or played because you can't have two of the same CheatPacks in one map.

Okay, Well i know how to do CPs but id need help with adding an Anti Cheat so if any1 of you Write one up thats pretty basic and explain where it would be put... In a PM(HAHA NOT PUBLIC ANYMORE! ^.^)

I don't basically know how to make anti-cheats but I made one for you.

Actually this is vJASS

[spoiler=Anti-CheatPack]

Code: Select all

scope AntiCP initializer Init
//****************************************************************************************
//
//    | Anti-CheatPack System v1.00                                       by Coleen |
//
//    Using this system will report any modification to the map script. Combined with map
//    optimisation it will effectively stop people from using a modified version of your
//    map, as it disables all GUI trigger functionality and all JASS triggers (with the
//    exception of libraries, for technical reasons) on detection of modification.
//
//    It is recommended that all functioning vJASS code is writeen within scopes (with the
//    exception of systems) in order for them to be disabled on modification detection.
//
//
//    Implementation Instructions:
//       
//     1. Create a blank disabled trigger named AntiCPConfig, convert to custom text
//     2. Copy/Paste the AntiCPConfig library into the blank trigger
//     3. Click the name of your map in the left-hand panel in the trigger editor
//     4. Copy/Paste the AntiCP scope into the Custom Text section
//        NB: The scope MUST be at the VERY top of the custom text section, and
//            NOT in a blank trigger
//     5. Follow the instructions in the AntiCPConfig library
//     6. Set the HANDLE_COUNT variable below to the output of the library
//     7. Configure other constants below
//     8. Set ENABLED = true
//     9. Save your map and enjoy
//
//        NB: Every time you save a final version run the AntiCPConfig library again
//            as the handle count has probably changed
//        NB: When modifying your map set ENABLED = false, and set it to true again
//            when a final version is saved
//
//****************************************************************************************
  globals
    //Output of AntiCPConfig library
    private constant integer HANDLE_COUNT = 0
    //System enabled or disabled
    private constant boolean ENABLED = false
    //Disable triggers initializers on detection?
    private constant boolean TRIGGER_DISABLE = false
    //Show a message to players if modification is detected?
    private constant boolean SHOW_TEXT = true
    //Text to display when SHOW_TEXT = true
    //If SHOW_TEXT = false it is recommended that this string be emptied (i.e. = "")
    private constant string DISP_TEXT = "This map has been modified. Please delete it and redownload from a trusted source."
  endglobals

  private function T2I takes trigger t returns integer
    return t
    return 0
  endfunction
  
  private function Init takes nothing returns nothing
    local integer i
    local trigger t = CreateTrigger()
    if (T2I(t) - 1048584) != HANDLE_COUNT and ENABLED then
      if SHOW_TEXT then
        call DisplayTextToForce(bj_FORCE_ALL_PLAYERS, DISP_TEXT)
      endif
      if TRIGGER_DISABLE then
        set i = i
      endif
    endif
    call DestroyTrigger(t)
    set t = null
  endfunction

//     1. Uncomment the 'requires' line above these instructions
//     2. Add in the name of every library in your map separated by ,
//       NB: If you have no vJASS libraries in your map ignore these two steps
//     3. Enable this trigger
//     4. Save your map
//     5. Click 'Test Map' and write down the number that is displayed
//        once the game starts (Handle Count: ...)
//     6. Exit the game
//     7. Disable this library
//     8. Keep this library within your map
//     9. Repeat these instruction every time you save a final version
//
//****************************************************************************
  private function T2I takes trigger t returns integer

The best way to learn to develop your own antihacks is to experiment, or, just think, what would stop YOU from hacking a map?

[haxorico]

anti cheats can even be stuff that are NOT commands. but corrupting the MPQ Archive...
a map with alot of files (like dota and foc) that has to get the MPQ Rebuilt and it wont be openable at x-dep / rmpqex would make it rly hard for ppl to hack it.

tho i believe every protection can be bypassed...

[Risen]

All can be broken, but the goal is to make it hard.

And un-doing an mpq corruption is rather easy, which is why I only do deprotection requests.

[UndeadxAssassin]

MPQ Corruption and that stuff goes more into protection than anticheats, though. A good anticheat wouldn't be detected as easily as bypassing some protection because all protections can be dealt with. The difference with anticheat is that if you don't want to ruin some of the things in the games, such as spells, anti cheat triggers are harder to remove if they're well coded.
