How to Use Game Rules in Minecraft

Gamerules allow changing specific things on servers like the day/night cycle, creepers exploding, mobs dropping items when they die, or even keeping a player's inventory upon death.

Preparation

The first step to using Gamerules is to make sure your account has been made a server operator.



Next, log into your Minecraft server.
