I created a recipe and block for crafting a mannequin mine. I was wondering if anyone knows of a way to set a target priority on a specific block for the zombie AI to attack. I wanted to create an exploding dummy using meat, nails, gunpowder etc and make it "appear" to be a player to that AI. Something that you could place and use either to take out a group of zombies or set up to be an early warning system. Thoughts?
