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 the "Edit Game Rules" menu built into the "Create World" screen $$. This menu lists all available game rules along with toggle buttons next to them for enabling, disabling, or setting certain game rules. The menu lists game rules split into specific categories depending on the effects of those game rules; these categories are player, mobs, spawning, drops, world updates, chat, and miscellaneous.

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).

List of game rules
The following is a list of game rules available in-game, their allowed values, and their availability in, , or both.
