Hi, i started playing PZ a couple of weeks and i really liked the game and now i want to make a mod that adds a new wall. The objetive of the mod is make a wall that only works as a fence, be indestructable and the zombies dont get atracted but i can't find a way to do that, im not new at programing but i am new at modding, if anyone known how to make this type of mod or knows abot a tutorial i will be really thankful.
