Set control flags

Using the Forms GUI

An easy way for beginners to set control flags in worlds is using the Forms GUI.

You can open the GUI using the command /worlds set (for current world flags) or /worlds defaults (for default world flags).

World control flags Forms GUI

The corresponding permissions are worlds.admin.set and worlds.admin.defaults, short commands are /ws st and /ws df.

Using commands

All commands require the permission worlds.admin.set, the short version of the commands is /ws st [...].

/worlds set show

List all flags and their values in a world

Examples: /worlds set show

/worlds set permission <permissionstring>

Set a permission which is needed to join the world (cannot be set on default world)


/worlds set permission you.arecool - Only players with the permission you.arecool are allowed to join the world

/worlds set gamemode <gamemodename>

Set the world's game mode (possible values are survival, creative, adventure or spectator)


/worlds set gamemode creative - Set the game mode of this world to creative

Control list flags

The following flags support control lists: see here.

They can be set to four possible operation modes:
