How do I "cut out" units?

[RabidSheepLegion]

I want to start a campaign, where there are no siege equipment IE Ballista, catapults, mangonels, trebuchets, etc. How do I make it so that no one can recruit them? I'd much rather not just delete them from EDU.txt

What could I do with this unit?

Open up the EDB.
Find the recruitment lines for ballistas, or whatever other unit you want to remove, (there's quite a few lines). Here's an example:
recruit_pool "NE Ballista" 1 0.15 2 0 requires factions { england, scotland, france, hre, denmark, spain, aragon, portugal, milan, venice, papal_states, sicily, norway, jerusalem, teutonic_order, }
Then comment out all those lines by placing a semi-colon in front of them:
;recruit_pool "NE Ballista" 1 0.15 2 0 requires factions { england, scotland, france, hre, denmark, spain, aragon, portugal, milan, venice, papal_states, sicily, norway, jerusalem, teutonic_order, }
Ballistas are now impossible to recruit.

so put semi-colons right before recruit pool?, if so, cool and thx!

[Meneth]

Correct.

[RabidSheepLegion]

brilliant, save game compatible?

[Meneth]

Yup.
Won't remove ballistas already on the map, though.

[RabidSheepLegion]

of course. In the words of Ren & Stimpy's advert for Log, "it's better than bad, it's good!" +rep!

Not meaning to double post, but superb results Meneth, thanks again!

Comment out siege works so AI factions dont waste money on them.

I'll let them build 'em

[Meneth]

Not save-game compatible.
You can't comment out buildings that have already been built.

[Caesar Clivus]

Maybe just reduce their cost and construction time to next to nothing so the the AI doesn't waste money or time building them.
