So I was making a trench warfare map and i needed grenades. So first i turned MobGreifing to false. Now, It works by taking the impact of a snowball (using armor stands to detect) and summoning a creeper with the following attributes: -Invisibility -Instant Fuse -Kinda Large Explosion Radius (about 3?)
I just need a /summon command. Thanks.
P.S. MobGreifing is false, so it's basically an entity killer.
