I am making a fully reset able survival games map. I am very early in development. If you would like to help solve some of my redstone/command block problems i will keep them here. Some features i plan to have are grenades and more customization then other maps. I will have problem/things i want to do in the map i cant figure out how to achieve in spoilers below.
I would like to be able to spawn a creeper that blows up instantly when you throw a snowball within 1 block of a player
