I am playing an MCPE hermit chunk map. There is 1x 16x16 chunk for me to work with, and so far no access to the nether. I have limited supplies, so the cheaper the better. Also, since I do not currently have access to the nether, comparators are out.
I have a mob grinder with a 2x2 hole down the middle. The mobs fall down this hole onto half slabs, die, and their items are collected by hoppers underneath the slabs. I am trying to find a way to visually tell when mobs fall through. I can either find a way to detect them falling in the hole, or their items being picked up. Either would be fine with me.
I would prefer to have a redstone lamp light up because I feel this is the easiest to see form a distance. I am currently on MCPE 14.2 (Windows 10 version, but basically same thing in this case)
I apologize if this has been asked, but I did a bit of searching before posting.
