I'm trying to figure out wiring; I have the following diagram, a heart statue hooked up to a 1-second timer. The timer is on, but the statue is not activating. What's wrong with my wiring?
According to the Terraria Gamepedia page about Heart Statues it could be because of this:
The statue also will not spawn a heart if there are 10 or more hearts anywhere in the world, 6 or more hearts within 800 pixels (100 blocks), or 3 or more hearts within 300 pixels (36 blocks).
Perhaps there are a few hearts somewhere underground below you?
