Limit a building to be built X times

Hi,

im wondering how to limite a building to be built only X times?

thanks


Edit: Id like to know how to make it a ressource droping location ty

Very simple trigger:


(You can tweak this as needed and play around with it)

As for the resource dropping, you need to go into the Object Editor and give it the ability Return Lumber, Return Gold, or Return Lumber and Gold

thanks! I was looking for an unit trigger hehe
