First Question is solved. So I edited it to only show the remaining question.

Another question I have is, can one force ai engineers to dispense health packs? I mean, it should act same as every other dispenser weapon but ai just ignores having it when I added some usual odf lines such as aitargetperson or maxrange stuff.

Same question as above goes to sniper Auto turrets, the AI refuses to dispense them 99% of time. And rocketeer's landmines as well, sure you can use the mine hint nodes but I'd rather they dispense them spontaneously to target enemies, plus there is the issue of engineers dispensing detpacks on mine hintnodes which is very annoying.

Thanks for insight

It's a trap! The engineers are trying to place an innocent looking health packs on top of mines so you'll be fooled and blow yourself up trying to get healed.

(sorry I can't help you)

The support class makes units with this line use the various damage and heal buffs more often. And im fairly sure the assault class makes the unit with that line attack vehicles more viciously. The trooper line of code makes that class attack other classes more often.

Yes I see, thanks. Anyone knows answer to the other question?
