Buildings that produce recources

[Tripod]

Hello.
I`m working on a little mod with a few new recources and tried to create a building that produces a recource.
The problem is , it should only produce it while you`re having an other recource and stop producing if you haven`t(same like Corporations).
Is there a way to do this in the XML files or do I have to change the SDK?(i`m afraid I can`t...)

Tripod, check one of The Lopez modcomps. code is already done there and ported to BtS 3.17 by some other modcomps/modpacks around here.

Thank you!
I think I found the right modcomp.Unfortunately no one with the code for bts 3.17 but I`l try to port it there by myself

It`s not so easy as I hope... Does anyone can tell me where I can found a mod/modcomp with the code for 3.17 inside.Can`t manage to get the code from Warlords to Bts
Edit : Finally I did it!!!
