Minecraft Creeper Damage. Damage done to mobs and players depends on how close they’re standing to the creeper. Creepers provide gunpowder, which can be used to create tnt, fire charges, splash potions, firework stars, and firework rockets.
In singleplayer, you have to have cheats enabled and use /gamerule mobgriefing false to disable creeper and ghast explosions as well as endermen picking up blocks. Charged creepers explode with a larger radius than uncharged creepers. Mobs deal no damage to players on peaceful.
