Hi, I'm creating a new civ, and i want to create an UA that provides produciton bonus when constructing Factory or Public School. Or maybe reducing production cost for factory and public school. (either way ok for me) I think it is not possible with xml. How about Lua ? Basically, i need to get what is constructing in city. If its factory or public school , give production bonus to city. Or if civilization type is my new civilization then reduce production cost for factory and public school. But how ? I searched and find this https://forums.civfanatics.com/threads/changing-a-citys-production-for-a-specific-building.564948/ But i couldnt figure out after that. This is my first modding try and i dont have any experience with lua. And also english is not my native language. I hope you guys understand what i'm trying to do.
