Just another update on BP series Party AI. Figure I'll collate everything I've found out so far (though I've no way to tell which are EE, EET or horred's bugs).
No way to toggle item use since the hotkey (E) is the quickloot one. When moving things in the inventory, there is a ~1 second lag if the item is equippable, making doubleclicking to split stacks impossible (as a workaround, put the stack in a container like bag of holding and take how much you need from there). Characters don't seem to recognise when their weapon is ineffective and switch to an effective one in the quickbar. Characters don't use spell stripping/remove magic spells (possibly getting an internal interrupt by default attack). Prebuffing hotkey fires at odd intervals for each party member, sometimes it works correctly (all 6 long-med-short), other times some lag behind. No way to reliably reproduce, sadly. Seems there is a bit of a conflict with new EE pathfinding down narrow spaces - characters will prefer to run the long way rather than wait for a free path (at least i think that's what supposed to happen in the EE). No one ever uses anything that can do friendly fire (possibly by design, though why not skulltrap a pack without characters). Wand and other item use seems extremely diminished from what i remember. Even with 2 full wands of magic missiles, I've had mages prefer the sling. Thieving mode only tries to hide in shadows and doesn't look for traps at all.
To be clear about my intent: I find features like threat assessment (both saving spells if fighting trash and rushing mages rather than closest enemy), prebuffing and running away rather than duking it out in melee for mages mandatory for any BG playthough, more so any SCS playthrough, just for the sheer amount of mobs it adds. I do not know the internal differences between EE and regular ai scripting (horred did say these are EE compatible, but that was obviously before 2.0). Seeing how badly SoD flopped, I don't think it's reasonable to expect brand new EE scripts, so I'm hoping you guys can at least port the best (as far as i know) original ones.
