I need help! Does anyone know how to add variables by themselves in V3? For example, for the recently updated morale and legality variables, if I want to add the variables I want myself, which file should I go to and write them? The reason I want to add variables is that I recently made a very impressive real estate mod, but the current market mechanism of V3 leads to a single price for a commodity like housing in all provinces of the country. My idea is that the housing produced in province A can only be used in province A, and the price of housing in province A is completely independent from the price of housing in other provinces. I would like to write a market access and commodity-related variable that can make the market access of a certain commodity, such as housing, to be 0, so that the above function can be achieved. Is there any game master who can help me or paradox staff who can help me to solve this problem.
