This thread fits the proper sub-forum because it's a reference of Lua code that many "inexperienced" coders lack at. It is highly RECOMMENDED that you DO NOT POST in this thread unless you are contributing Lua code or any alternative that suits for a reference that we don't have to flip to. In the OP, I'll answer some questions that may be asked. Q: What are dummy policies/buildings? A: Policies and buildings that output an effect desired to the modder, but (not necessarily) hidden from the player's view. An example would be simulating an increased resting point for a Civilization's UA. You would implement a dummy policy to do so. Hidden to the players, they would see the UA to be affected while to the modder and experienced players behind the framework is a dummy policy doing it essentially. Q: What are the limitation of dummy policies/buildings? A: Question was already answered. It's limited to what policies and buildings can do. This is where custom DLC scenarios can come in handy as they may have effects that the BNW package may not have, but still work. Alternatively, if you're willing to use a custom DLL, VMC and CP makes use of the "unified yield" element which can help you not use Lua to simulate effects. Q: What if I don't understand the Lua? A: It's not that hard to understand, it's plain English. You just need to substitute the VARIABLE(s) with what fits your XML entries. Q: What is this vault really? A: As there is a demand, a reference can be made so that other modders can reference to easily without having to look into other people's mods. If there are any errors, you should PM me personally or whoever made the reference rather than commenting here directly.
