How to make a Campaign AI

mckill2009 · Feb 8, 2012

Seriously, if only melee AI creation, its still best and easy to configure it in GUI mode, and
just do the rest of the attacking/engaging in triggers, but good tutorials anyway...

Well, GUI AI editor has its limitations.

It only allows you to define a random selection of 3 heroes instead of 4.
If you define conditionals too long, it fails (it truncates the code generating errors)
And... it's slow to develop.

So... the best is to write you own AI Jasscraft and it's done

And with this you can optimize the AI process and add more awesome control over it.

Great tutorial. Nice explanations and great for those who want to learn how to create an AI using the common.ai scripts. =)

This is in an approvable state, but two things should be fixed first:
1) The links to JassCraft and Jass Shop Pro link to random hive maps. (lol) Replace those links with the ones from wc3c.net
2) One of the JASS tags has everything on one line. Under the category "Attacking Strategy"

Once those changes have been made this will be approved!

About the second point, it seems it's a bug with the jass script of the site, I tried to edit it, but nothing changes

JASS:

function main takes nothing returns nothing    
    local unit crp    

// Building code goes here 
   
//*** WAVE 1 ***    
    call InitAssaultGroup()    
    set crp = GetCreepCamp(0,9,false) // Stores the target unit    
    call CampaignAttackerEx( 2, 3, 3, ARCHER )     
    call CampaignAttackerEx( 0, 1, 2, HUNTRESS )     
    call Sleep( M3 ) // Waits 3 minutes before attacking    
    call AttackMoveKillA(crp) // Order assault group to attack that unit
endfunction

How about this? You could also try copying the code into something like WordPad before pasting it into your post.

I already did this, and it didn't worked.... weird....

PurgeandFire · Feb 14, 2012

Hmm.. I've tried it as well and it didn't work. Anyway, I've detached the signature and approved.

I'll try to work out a resolve for that bug or I will report it if I find time.

Higher Hero Levels

Hello moyackx!!

Well, I have a question...I've benn messing with the W3E for some years(Since 2005), but I started to study vJass these days(I'm already a programmer for 4 years...but I was too lazy to leave GUI and learn vJass :grin:

)
Anyway, in the AI Editor, if I put more than 1 level to the ultimate spell, it breaks.As it breaks if I put more than 3 levels on others spells.
I'll try this tutorial after work when I get home, but if you see this question before maybe you can answer me

The question is...If I make an AI this way(triggers and vJass) will it break if I put more levels on the ultimate or other spells??? :ogre_hurrhurr:

moyackx · Jul 6, 2012

Technically no, because with triggers you have more control over you do with units. AI coding is filled with more "hardcoded behavior" than normal triggering.

I should try an example though to see if it works.

According to your code you give 10 seconds to the units to do the attack. SuicideOnPlayerEx does a wait in the for that time while the AI does the job.

Sorry I really didnt get your answer, you mean to say that I should increase the wait?, I already did that for 60,120 etc... and it doesnt work...

SuicideOnPlayerEx calls many sub functions so I went to the root of it (CommonSuicideOnPlayer), unfortunately IDK how those function works after that...

And again, ONLY the loop doesnt work, the first attack is OK...

I mean this :

Change this:

call SuicideOnPlayerEx( 10, 10, 10, AttackTo ) // right now the AI wait 10 seconds, you need minutes in order to let the AI do the job

For this: call SuicideOnPlayerEx( M10, M10, M10, AttackTo )

And tell me if it works. As far as I remember, SuicideOnPlayerEx does a sleep internally.

mckill2009 · Aug 29, 2012

Like I said:

I already did that for 60,120 etc... and it doesnt work...

coz M1=60, M2=120

I think it doesnt really matter if it's in seconds or minutes coz if I put 1 second, the AI will almost attack immediately on first wave, next waves no more...

EDIT:
Tested it again for 5 seconds, works for first, second waits for at least 3 minutes, the rest loop waits for 5 seconds only...
The second wait is now bugged with minutes of interval, IDK why...

Starquizer · Jan 10, 2013

Set replacements is not working, why ?

Take a look at this thread I make.

Wa666r · Mar 29, 2013

Help me out?

So I've only started with vJass programming. I know how to deal with the AI editor but its very choppy and usually doesn't work for too long :ogre_frown:

.
But anyways, I made the code for humans but for some reason they dont build or do anything when I test them. Could you find the problem and help me out?

(Sorry I'm don't usually post much on this website, so unsure how to upload the files)

Starquizer · Mar 29, 2013

you have a syntax error at line 5 before the end of the script "endloop": you didn't start the loop in the first place.

JASS:

loop
    // some actions ...
endloop

you are making

JASS:

// some actions
endloop

I would suggest you do this for every AI you make to know it has no errors, add this line under the main function

JASS:

function main takes nothing returns nothing
   call DisplayTextToPlayer(Player(0),0,0,"AI started")
   // Start you AI

endfunction

When you run the game and you get the message "AI started" then your file will work properly, otherwise, it contains an error(s).

Wa666r · Mar 31, 2013

Sorry again I tried to fix the other Ai but it didn't work, so I decided to mimic your Ai but instead with humans. Needless it doesn't work and I do not why?
When I test that Ai in the Ai Editor, the night even ai works while my human ai just mines gold. So could you help a beginner out again?

I suggest to use Jasscraft: http://www.wc3c.net/showthread.php?t=80051&highlight=jasscraft as your AI editor, it helps detecting typos because it uses pjass as syntax checker. when you test it, ensure you set common.ai and common.j in the settings dialog (F8) in the "jass enchantements" tab. This in order to do the proper debugging

Wa666r · Mar 31, 2013

It works!!

Thanks a lot man!
But hey, how would you upgrade towers, would it just be: call SetBuildUnit( 1, 'hgtw''' ) ?

No, you don't need special codes for JASS based AI, but remember, JASS AI used Rawcode, be sure to check the rawcode of every costum unit you use, since incorrect rawcode causes the AI to break and don't work.

If I'm wrong, I'm very sorry, that's because I don't make Camp. AI's, so very sorry if that happened.

In the object Editor Press CTRL+D and check the rawcodes of the units/buildings/abilities. Those can be used in your custom race and it will work for you.

What does it mean when the custom AI gathering 10 gold instead of the slow harvest 1 gold? Even if I have this: call SetSlowChopping( true )

You may have errors in the script and it is not running at all, which will make the AI player do nothing except gathering resources.

KONSTANTIN · Jun 29, 2013

hi. first of all i wanna thank moya for this nice guide, cuz im a total newb when it comes to ai and jass.
i wanted to make campaign ai that doesnt mine gold, with custom units from a modified race that will attack occasionaly when triggered. this is my script
of course i gave him gold and lumber, when runs out it recharges again. i made a modified structure Orc Fortress that would make him primary food limit of 90, without need to build extra burrows, but then i just changed it to regular burrows in his camp.

KONSTANTIN · Jun 29, 2013

tried it, didnt work. i downloaded jasscraft for error fixing and comparing to common.ai. tried multiple times checked, and checked again and again and nothing seems to work, then i just made it simple and used onyl 3 custom units for player with one producing structure. then i played with common.ai cause i saw blizzard done that when they used custom units in campaigns...

constant integer SKEL_ORC = 'nsko'
constant integer SKEL_ORC_GRUNT = 'nsog'
constant integer SKEL_ORC_CHAMP = 'nsoc'

i insterted this in common.ai and saved thru mpq in frozen throne mpq file.

jasscraft recognized this functions from common.ai and said there were no errors, but then it still doesnt work.. am i doing something wrong in the map itself maybe, cause i linked ai to player, and sent commands (0,0) ? it uses orcs structures with custom units, so i think its ok to link food producer to be orc burrow

Daffa · Jul 1, 2013

Where's the build order?
Also, use Jass tag when posting the code.

KONSTANTIN · Jul 1, 2013

as i said in previous post there is none. i need this ai only for attacking and defending without mining, repairing units. i mimicked the script from blizzard ai in wc3 when they used the script for "Corrupted Ancients" the exact same thing i want to use here.

oh and sry about not using code earlier...

KONSTANTIN · Jul 3, 2013

so... any ideas ?

moyackx · Jul 3, 2013

are there buidings that actually can train those skeletal orcs?? if not, then that's the reason of your issue

KONSTANTIN · Jul 3, 2013

of course. i set orc barracks to train them. they just wont do anything, wont move, wont train nothing.

just a thought did maybe blizzard set some special behaviour for custom units or something that i should be aware.. ?
here is a pic of ai triggering i did.

moyackx · Jul 3, 2013

Ok, I saw the issue:
function ConfigureAI takes nothing returns nothing

Change it by:

function main takes nothing returns nothing

KONSTANTIN · Jul 3, 2013

i get nothing...

moyackx · Jul 3, 2013

Ahhh... please remove call WaitForSignal()

KONSTANTIN · Jul 3, 2013

hey man IT WORKS FINNALY!

its not the signal, its just me FORGETING TO IMPORT COMMON.AI IN WC3 folder data. JESUS CHRIST. i was working from the start from my copied .mpq files in another directory and then when milions thing got complicated about directories being protected and taking ages to copy paste 400 mb mpq files over and over cause of testing i was just fuck it lets try one more time with raw names, and voila. moya im rly sry about wasting your time, i just started this map moding like 10 days ago, and it finnaly works after days of testing, im happy AS FUCK!!

ps i just found out that i actually DID copied mpq in wc3, its just when reading integers in jasscraft one name of one unit was marked in white while others were silver. and raw was right i checked! so i dunno why it didnt wanna get raw out of that unit...

Abextadoo · Jul 20, 2013

is there a place in the site where we can download pre-made AI? i've been looking for a while but it seems like no..

I think there a few pre-made scripts but they are few as a few people care about AI, you will have to search the web for them but I think it is better to make your own script.

PrinceOfThaWest · Sep 7, 2013

This tutorial helped me a lot. However I managed to learn basic AI script thanks to Demo Custom Campaign made by Blizzard Entertainment. They provided basic script there which is used for Humans in first chapter. However yes, JASS AI making surely is the best. I'm still trying to get it under hand, so far so good.

If you also need to know the description of most of the AI natives go here (the AI manual) as well.

With those 2 tutorial you could master your AI scripting skills.

I am still sort of newbie for this whole JASS thing, to be honest. I barely know to code that much but I managed to compile some skills out of this tutorial and demo campaign made by Blizzard. There are still some things I'm yet about to learn when it comes to Campaign AI scripts but yeah, I'm on a good way.

I guess the Orc campaign that was in the demo of WarCraft 3, the one that Thrall stuck on an isle facing murlocs.

MasterHaosis · Sep 9, 2013

Ah yes. And that campaign has imported custom AI?

PrinceOfThaWest · Sep 11, 2013

Yes, that campaign. And yeah, there are custom AI made by Blizzard specially for that campaign.
