[AI] Problems with Custom Campaign AI

Datage · 2025-06-30T17:49:04+0100

Hello! I have been trying to use Jass to make an AI for a Custom Campaign. However, once the level starts and the appropiate triggers are detonated, the computer does nothing?

Here is the code:

JASS:

//------------------------------------------------
//              GLOBALS
//------------------------------------------------

globals
    player user = PlayerEx(1)
    
endglobals

//------------------------------------------------
//              MAIN
//------------------------------------------------

function main takes nothing returns nothing
    call CampaignAI(ZIGGURAT_1, null)
    call DoCampaignFarms(true)
    
    call SetHeroesFlee(false)
    call SetGroupsFlee(false)
    call SetReplacements(1, 1, 1)
    call SetSlowChopping(true)
    call SetPeonsRepair(true)
    
    call SetBuildUnitEx(1, 1, 1, NECROPOLIS_2)
    call SetBuildUnitEx(1, 1, 1, UNDEAD_MINE)
    call SetBuildUnitEx(6, 6, 6, ACOLYTE)
    call SetBuildUnitEx(2, 2, 2, CRYPT)
    call SetBuildUnitEx(2, 2, 3, GHOUL)
    call SetBuildUnitEx(1, 1, 1, UNDEAD_ALTAR)
    call SetBuildUnitEx(1, 1, 1, DAMNED_TEMPLE)
    call SetBuildUnitEx(1, 1, 1, GRAVEYARD)
    call SetBuildUnitEx(6, 6, 7, ZIGGURAT_2)
    
    call CampaignDefenderEx(3, 3, 4, GHOUL)
    call CampaignDefenderEx(1, 1, 2, NECRO)
    call CampaignDefenderEx(1, 2, 2, CRYPT_FIEND)
    call CampaignDefenderEx(0, 1, 1, BANSHEE)
    
    call WaitForSignal()
    
    // WAVE 1
    
    call InitAssaultGroup()
    call CampaignAttackerEx(4, 4, 4, GHOUL)
    call SuicideOnPlayerEx(180, 180, 150, user)
    
    // WAVE 2
    
    call InitAssaultGroup()
    call CampaignAttackerEx(3, 3, 4, GHOUL)
    call CampaignAttackerEx(1, 1, 2, NECRO)
    call SuicideOnPlayerEx(180, 180, 180, user)
    
    // WAVE 3
    
    call InitAssaultGroup()
    call CampaignAttackerEx(4, 4, 5, GHOUL)
    call CampaignAttackerEx(1, 2, 2, CRYPT_FIEND)
    call SuicideOnPlayerEx(180, 180, 180, user)
    
    // WAVE 4
    
    call InitAssaultGroup()
    call CampaignAttackerEx(4, 4, 5, GHOUL)
    call CampaignAttackerEx(1, 1, 2, BANSHEE)
    call SuicideOnPlayerEx(180, 180, 180, user)
    
    // WAVE 5
    
    call InitAssaultGroup()
    call CampaignAttackerEx(3, 4, 4, GHOUL)
    call CampaignAttackerEx(1, 1, 2, NECRO)
    call CampaignAttackerEx(0, 1, 1, BANSHEE)
    call SuicideOnPlayerEx(180, 180, 180, user)
    
    loop
        
        // WAVE A
    
        call InitAssaultGroup()
        call CampaignAttackerEx(5, 5, 6, GHOUL)
        call CampaignAttackerEx(1, 1, 2, NECRO)
        call CampaignAttackerEx(0, 0, 1, MEAT_WAGON)
        call SuicideOnPlayerEx(180, 180, 180, user)
        
        // WAVE B
    
        call InitAssaultGroup()
        call CampaignAttackerEx(4, 4, 6, GHOUL)
        call CampaignAttackerEx(2, 2, 2, CRYPT_FIEND)
        call CampaignAttackerEx(1, 1, 1, BANSHEE)
        call SuicideOnPlayerEx(180, 180, 180, user)
        
        // WAVE C
    
        call InitAssaultGroup()
        call CampaignAttackerEx(7, 7, 9, GHOUL)
        call CampaignAttackerEx(0, 1, 2, CRYPT_FIEND)
        call CampaignAttackerEx(0, 0, 2, MEAT_WAGON)
        call SuicideOnPlayerEx(180, 180, 180, user)
        
        // WAVE D
    
        call InitAssaultGroup()
        call CampaignAttackerEx(4, 4, 4, GHOUL)
        call CampaignAttackerEx(0, 1, 2, CRYPT_FIEND)
        call CampaignAttackerEx(1, 2, 2, NECRO)
        call CampaignAttackerEx(0, 1, 1, BANSHEE)
        call SuicideOnPlayerEx(180, 180, 180, user)        
        
    endloop
endfunction

Now, I had a similar issue in the past, which was due to a Syntax Error. However, I've run this code over the few Syntax Checkers I managed to get working, and they didn't report anything out of the ordinary. Could someone please tell me where the mistake is?

You may want to specify this for their workers (whatever values fit your map)

JASS:

set campaign_gold_peons = 5
set campaign_wood_peons = 4

"DoCampaignFarms" I don't think I've ever seen used, although Blizzard does this:

JASS:

set do_campaign_farms = true

I'm not sure about PlayerEx(1), have you tried Player(1)? Also remember that Player 1 in the script = Player 2 in the editor.
Finally, do you send a command so that it can respond to WaitForSignal()?

Footman16 · 2025-07-01T08:27:18+0100

When you say it "does nothing" do you mean the entire computer player does nothing including Acolytes NOT collecting gold? Or does the script run but it just doesn't send attacks?

So, after trying the suggestions, the script doesn't still doesn't work.

JASS:

//------------------------------------------------

    player user = Player(0)

    set campaign_gold_peons = 5
    set campaign_wood_peons = 4

        call SuicideOnPlayerEx(180, 180, 180, user)        
        
    endloop
endfunction

The weird thing about this, though, is that a code nearly identical to the original one does work on a normal non-campaign map, so I'm not really sure of what's happening here.

As for the triggers, both seem to be working properly: The AI is loaded in with the player's resources, and the signal is sent when the heroes are loaded in; which as far as I can tell, are running without an issue.

As for what it does... well, nothing! The acolytes don't harves the mine, the ghouls don't chop trees, and it doesn't train anything: Nor garrison nor attack waves.

Ok if it does literally nothing then there's a syntax error somewhere, either a typo or a reference to a variable that doesn't exist.
