There are certain limitations to the game engine atm - your perceived 'stupidity overload' is the result of, sorry to says that, your ignorance towards them:

Obviously it has limitations, and obviously all game engines have limitations. But, sorry, your second clause is exactly reversed. The perception of stupidity here is a result of learning about those limitations, not of being ignorant of them.

1) Commanders do what they are ordered to - literally. They do not 'think about' what might be your intentions. The only freedom of choice is what spell to use when ordered to 'cast'. In that case, the AI will mostly go for buff (target:self) spells first. If there are targets in range, the battle engine will try out several different ranged spells and choose the one which deals the most damage. That does not mean it will do maxed damage, or any damage at all, because the random factors are newly calculated when the spell is actually cast.

Actually, that's the point, they DON'T just do what they're ordered to do. As you point out, there are several things they will do without being ordered to do. AI is difficult programming, I realise as well as anyone, and practically speaking it's impossible to get it perfect. I don't expect that.

I did expect, however, an AI that with some basic, fairly simple logic checks like 'don't cast this spell if it's more likely to harm your own troops than the enemy' or 'don't move close to friendly troops when you have an area of damage effect following you around.' That seems pretty elementary.

2) Units do not 'know' about battlefield hazards. They move into poison clouds as well as into a breath of winter. Likewise, units do not 'know' about their own auras/fields.

That's a pretty severe limitation, and quite an annoying one from a gameplay perspective, but it wouldn't actually be necessary to fix that to stop what I'm talking about.

Ok, another quick test:

A mage who is ordered to "cast spells", but can cast absolutely no spell defaults to "stay behind troops" it seems. (E.g. Blood-1 mage without slaves and low research - only spell would be 'bleed' which requires a slave).

Yep. It will do that even if not given that command.

"sometimes cast BoW THEN run to where it can inflict the most casualties"

Obviously, the only spell the mage could cast at that time was BoW. As he was ordered to cast, he did just that. Afterwards, he was ordered (by the game engine) to "stay behind troops" - and he did just that.

Sounds right. And easily fixed, by anyone that has access to the code, one would think.

Quote:

"sometimes run to position first, THEN cast BoW"

Behaviour like that I couldn't recreate unless I ordered the mage to move via "attack" order. If ordered to cast a specific spell 4x and then cast spells, the mage always stays put until running completely out of spells. In that case, he casts "BoW" first and moves on the next turn.
Exception might be heroically quick or quickened mages. The additional action points screw up the order of orders (if that makes sense).

It does, actually, as the latest observation of that behaviour was out of a severely quickened unit. (A random R'lyeh hero, Traitor King? or something like that, L4 water mage with heroic quickness and the spell quickness as well. Definitely NOT ordered to attack or stay behind troops. I have the save game stashed to look at again if there's any point in it.)

"to where it can inflict the most casualties on their own side"

As unit do not know about auras, fields, units around them (other than who is 'rearmost', 'nearest', 'archer' etc), they can't deliberatly run where they can cause the most casualties. They go for the rearmost unit. Simply make sure your rearmost unit is 100% cold-resistant and keeps a healthy distance from the rest of your troops and you'll be fine. If you bunch up all your vulnerable mages, either by setup or use of "stay behind troops", the 'stupidity overload' is surely not on the games side http://forum.shrapnelgames.com/image...ies/tongue.gif

Your rearmost unit, if you have archers, is pretty much always going to be those archers. In this case, as I recall, I had my Illithids (archers in the broad sense) on the right hand side, firing. The melee troops were spread across right-middle and slightly forward, and the assorted mages spread across the back row tending toward the left, with the exception of the hero with the BoW fixation, who was on the far right side and forward, just behind some melees, to keep him as far as possible from other troops when his casting orders ran out, on the basis of previous assertions on this thread. The melees move forward, the illithids fire, the mages cast... for several rounds it's all working well. Then, I'm guessing, what happens is that in the final rounds of the battle, as the spell ques empty, the battle has been won, the enemies are all in flight... and at this point there's no more targest for the spell casters. So they all run and bunch up behind the illithids. The earlier posters on this thread had said this was because I was using the 'stay behind troops' command, remember, so I was testing this and not using the command, and it happens anyway.

I can't believe I'm the only one that finds this beyond annoying. It's absolutely senseless. And fixing it wouldn't require any radical expansion of the AI engine so far as I can see. Simply disabling that forced 'stay behind troops' command you hypothesise (and it matches my observations) would pretty much do the trick. There's no need for mages to be moving around and casting spells when all enemy forces have broken anyway (and that's always or very nearly always when this happens - AFTER all enemies have broken.)
