Lord_Kane: Didnt Warcraft II's DOS and BNE's AI use a trigger based system? because those systems dont always work right.

Szwagiermc: In orginal campaign human TOD mission 11, where we need destroy all transporters

morolf: iirc that's the seventh mission (11 is where you're fighting against human Alterac)...interesting, always wondered why you don't get attacked at all in that mission.
I just played Beyond the dark portal 4th human level, and that seemed to work as intended, got attacked by two enemies (one with ground troops including catapults, one with dragons).

Szwagiermc: No its 12th :P

in 7th teal job is doing nothing :P

Jann180: Are there differences between the BNE and DOS versions in the AI script?

Because I swear I remember playing that mission as a kid (in the DOS version without expansion) and the AI in the 12th mission kept attacking me over the course of it. Same in 13th.

Now they do one attack at most, then stop doing things completely.

Szwagiermc: I dont know, I had also DOS version but I got bne since 2002, I havent tried to edit dos version cause bne is better :P, blizzard edited w2 and make mpq file like all their games (sc/scbw/w3/w3tft)
Also when I was young I remember in first mission human there was troll under hall, or tower guard mission 2

Jann180: Yes! I remember that guard tower in mission two as well. Never seen it since. Damn, I should really replay the DOS version sometime. Wish it came out with the other ones here as well.

Edit: I've played the DOS version again (about first 5 missions in the human campaign) and sadly I already feel the difference. The AI actually works and attacks you (upgrades watch tower in mission 2!). Can also tell other slight differences in how the game works and that the music is longer (also, I think each mission only plays one track rather than cycling through every one).

Really makes me a bit sad, because I only play Warcraft 2 for the singleplayer and while BNE, which I've played for ages, gives you a ton of improvements, the breaking of the AI is one of the things that just completely eliminates the feeling of the original (actually fearing being attacked early and by stronger attacks later on).

Szwagiermc: But how computer can upgrade Tower without Mill? I think map is allready done with guard tower

Jann180: I've noticed the AI just gets "stuck" like sometimes and it kind of bothers me. It happens a lot in the original campaigns. I remember some missions you could get attacked relentlessly, but other times, the AI would do absolutely nothing at all. I'm not sure about the trigger system honestly, because a lot of times when the AI was aggressive I didn't even move out of my starting areas and other times, when being all over the map, it wouldn't do anything (like others said, just mining gold, not building ANY units, researching upgrades, or even repairing).

Save and reload would sometimes help and the AI would suddenly "activate".

I played the last mission in the ToD human campaign yesterday and black didn't make a single peon (full gold mine for me, I guess). And the mission before that often used to be scary as both AIs would send transport ships full of ogre mages that would attack you, except not this time. They did one pathetic attack at the beginning of the mission, then stopped entirely. I even played with the AI to see if there was something I could do to make it active. Somehow I made it do some upgrades eventually (most of the map was conquered already), but then it would stop again. I just don't know.

The only trigger I know of (universal) is when you destroy second to last, or last building of the AI, it will send all units to try and attack you (even peasants lol).
