Using gamerules in Minecraft

Gamerules control various aspects of the gameplay, and provide a lot of customization for server owners.

Gamerule Commands

How to Set the Value

/gamerule <rule name> <value>

How to Get the Current Value

/gamerule <rule name>

A rule name is the name of the specific gamerule that you would like to set, or view. A list of these can be seen below.
The value is the value you wish to assign to a specific rule name. In the majority of cases, this is a boolean true or false value, but can sometimes be a number.
Each command must be entered into either an Admin/OP's chat in game or in the server console.
For Bedrock servers when the command is entered in the server console the "/" must be obmitted, otherwise the following error will occur: Unknown command: /. Please check that the command exists and that you have permission to use it.
The following example uses the gamerule fallDamage in the Nodecraft server console for Java:
