Game rule

Game rules are a set of customizable options for a specific in-game world.

Modifying game rules
$$, game rules can be changed using toggle buttons on the "Edit Game Rules" menu built into the "Create World" screen. The game rules are split into categories named "Player", "Mobs", "Spawning", "Drops", "World updates", "Chat", and "Miscellaneous".

$$, many (about half) of the game rules can be changed using toggles on the "World settings" and "Cheats" sections of the world's Game settings screen. The remainder can only be changed with commands.

When in-game, game rules can be changed using the command, using the syntax, where  is the name of the game rule and  is an allowed value, which depends on the type of the game rule. The types are boolean (where the allowed values are either ) and integer (where any whole number is able to be entered).
