[Trigger] How to detect "Single Player"?

[sephiroth1234]

Hello... Could I ask on how to detect Single Player gaming mode? Because I am creating an anti-cheat system on my map. JASS or GUI versions are accepted but its better for you to send me a GUI version. Thanks!!!!!

Count the number of non-computer players in the game

Thanks!!!

Yes! I tried your recommendation and it worked! Thanks to you(+rep 4 u)!!! As you see, I followed the tutorial at this link:http://clancbs.com/board/showthread.php?t=2802 which is more complicated than the one you recommended, I also followed the correct sequence of the tutorial but when I tested it, the system also initializes even if I tried it in Multiplayer. Anyway Thanks for your reply!!!

My method won't distinguish between playing in Single Player mode, and just having one player in a Multiplayer mode.

That link you posted is 2 years old and will no longer work as of a patch a while ago.

There's an easy way to do this which I used in a map I used to work on but sadly I dont have the map right now and I forgot the exact method but its just a single line boolean check using some kind of bj_xxx ...

anyway I checked the link and why would that not work in the new patch?

If you want a simple check, do this:

• Custom Script: if bj_isSinglePlayer then
  • //do your actions
• Custom Script: endif

Blizzard initially sets this variable when the game starts/initializes:

set bj_isSinglePlayer = false
    set userControlledPlayers = 0
    set index = 0
    loop
        exitwhen index >= bj_MAX_PLAYERS
        if (GetPlayerController(Player(index)) == MAP_CONTROL_USER and GetPlayerSlotState(Player(index)) == PLAYER_SLOT_STATE_PLAYING) then
            set userControlledPlayers = userControlledPlayers + 1
        endif
        set index = index + 1
    endloop
    set bj_isSinglePlayer = (userControlledPlayers == 1)

But there was a slight debate about the functionality of it:

Hmm. For some reason that bj_isSinglePlayer doesn't show in the Jasshelper function/constant listing.
Anyway, that is essentially the method I posted above, it counts the number of human players in the game, but doesn't distinguish between playing in single player mode, and having one player in a game on LAN/battle.net.

of course it wont show in the function list... all bj constants doesnt show up there since they are not functions...

anyway when I used that trigger, it will only return true when the game is single player but returns false when you play on LAN even with only one player...

 

[Teelo]

Other constants show in that listing if I change it to list constants instead of functions. That one isn't there though.

The method works perfectly fine, so you shouldn't have any problems if you imported it correctly.
Did you use the Jass-version or the GUI-version?

That link you posted is 2 years old and will no longer work as of a patch a while ago.

Which patch?

Ehrm, it's easy I think, here's the trigger I made for you, and i think it should work, otherwise use After 0 second of game time.

• Single Player Detection
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set SPD_Group = (All players controlled by a User player)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of players in SPD_Group) Equal to 1
      • Then - Actions
        • -------- You'r actions here --------
      • Else - Actions

tjordell, yours also kicks a player who plays alone in a LAN/battle.net-game.

I know another solution that does exactly what the thread starter wants without using game cache. It uses the nice function "Cheat" which does just that: it uses cheats. (And works only in Singleplayer-Mode, just like the normal cheats) ^^

function Trig_AntiSinglePlayerMode_Kopieren_Actions takes nothing returns nothing
    call Cheat("greedisgood 1000000")
    call TriggerSleepAction(0.01)
    if ( GetPlayerState(GetLocalPlayer(), PLAYER_STATE_RESOURCE_GOLD ) == 1000000 ) then
        call CustomDefeatBJ( GetLocalPlayer(), "No Single-Player-Mode!" )
    endif
endfunction

 

[TriggerHappy]

• Custom script: if (not ReloadGameCachesFromDisk()) then
• Game - Display to all players "The game is online!"
• Custom script: else
• Game - Display to all players "The game is offline."
• Custom script: endif

meOme, could you post a GUI version of that JASS code? so I can understand it more easily. Thanks!

TriggerHappy, your recommendation is accurate but do you know another way of detecting Single Player without using game cache functions?

It cheats the "greedisgood" cheat, then checks the players gold. If the cheat worked (only works in singleplayer mode) then it gives them a defeat.

Yes we have all posted half a dozen methods in this thread already. Why do you want more, or what was wrong with the ones we provided you?


To check if its just one player in the game (single player), then count the number of human players in the game.

To check if its single player mode, then either mess with the gamecache, or try and force a cheat then check if it worked.

I followed the other posts but some have bugs like when I test my map and it loads, it prevents the map from loading and I tried some but the map also initialize the trigger even when I test my map in Multiplayer mode.

Ok, I tried to make it the least custom script possible:

• AntiSinglePlayerMode
  • Ereignisse
    • Zeit - Elapsed game time is 0.00 seconds
  • Bedingungen
  • Aktionen
    • Custom script: call Cheat("greedisgood 1000000")
    • Wait 0.01 game-time seconds
    • For each (Integer A) from 1 to 12, do (Actions)
      • Schleifen - Aktionen
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • 'IF'-Bedingungen
            • ((Player((Integer A))) Aktuelles Gold) Gleich 1000000
          • 'THEN'-Aktionen
            • Spiel - Defeat (Player((Integer A))) with the message: No Single-Player-Mode!
          • 'ELSE'-Aktionen

Of course you could also use other cheats, if you don't want the "1000000" popping up in the gold/lumber values.

But if you input this JASS code, you don't have to do anything with it, it's complete in itself: it'l just defeat the player in singleplayer

I just gave him what he asked for. ^^

anybody can just change the line that contains the defeat if they want other things to happen...
