I'm somewhat of a newbie at creating these amazing AFK farms the geniuses in this threat have come up with. Looking in the question thread, I found a question and answer about spawn rates, but would like a bit more detail. I was wondering the exact amount of blocks you need to block around you to restrict spawns to a small platform. The wiki and other sources say "off screen," but since I play Terraria in a smaller window while watching vids or doing something else, I'd like to know the universal distance. Thanks so much!
