The World Editor

Change any single world's settings from one menu.

/worlds edit [world] opens the editor for a single world. With no argument it edits the world you are standing in.

This is where nearly every per-world setting lives. Each control has its own permission, so you can hand out a subset: a builder who may change the status but not the visibility, for example.

• Permission: buildsystem.edit, which supports the .self and .other suffixes so you can allow editing your own worlds only.

Controls

Identity

Control	Permission	What it does
World item (top row)	buildsystem.edit.icon	Opens the item picker to choose the world's icon. Right-click a player-head icon to set its skull texture instead.
Pin	buildsystem.edit.pin	Keeps the world at the top of every navigator list, above the normal sort order.
Status	buildsystem.edit.status	Opens the status picker. Status decides which navigator tabs list the world, and whether building is allowed at all. See Custom Statuses & Categories.
Project	buildsystem.edit.project	Prompts in chat for a free-text project tag, shown in the world's lore and /worlds info.
Permission	buildsystem.edit.permission	Prompts for the permission a player needs to enter. Enter - to remove the restriction. Restricted by settings.world-permission-whitelist if you have set one.
Visibility	buildsystem.edit.visibility	Switches between public (EVERYONE) and private (ADDED_PLAYERS). A barrier icon means you lack permission to create that kind of world, and clicking does nothing.
Builders	buildsystem.edit.builders	Left-click toggles the builder whitelist on or off. Right-click opens the builder list. While enabled, only the creator and added builders may modify the world.

Protection

Each of these is an independent switch. Turning one off blocks that action for everyone without a bypass.

Control	Permission	Blocks
Block breaking	buildsystem.edit.breaking	Breaking blocks.
Block placement	buildsystem.edit.placement	Placing blocks.
Block interactions	buildsystem.edit.interactions	Right-clicking chests, doors, buttons, and everything else interactable.

buildsystem.bypass.settings overrides all three at once.

World Behaviour

Control	Permission	What it does
Physics	buildsystem.edit.physics	Left-click toggles physics for the world. Right-click opens the exceptions menu, covered below.
Explosions	buildsystem.edit.explosions	Whether TNT and creepers damage terrain.
Mob AI	buildsystem.edit.mobai	Whether mobs move and act. Off leaves them frozen in place, which is useful for posed builds.
Time	buildsystem.edit.time	Cycles the world's time between sunrise, noon, and night, using the values from world.defaults.time.
Difficulty	buildsystem.edit.difficulty	Cycles Peaceful, Easy, Normal, Hard.
Game rules	buildsystem.edit.gamerules	Opens a paginated list of every game rule. Booleans toggle, numeric rules increase by 1 on right-click and 10 on shift-right-click.
Remove entities	buildsystem.edit.entities	Deletes every entity in the world and reports the count. Players, and a small set of protected entity types, are left alone.

Remove entities cannot be undone. It clears armour stands, item frames, paintings, and dropped items along with mobs, so it will strip decoration from a finished build. Take a backup first if you are not certain.

Physics Exceptions

Physics used to be all or nothing. Right-clicking the physics toggle opens a menu where individual behaviours keep working while the world's physics stay off.

Category	Covers
Block updates	Attached blocks such as torches and rails popping off, and block shape updates.
Connections	Fences, gates, glass panes, stairs, and walls joining to their neighbours.
Falling blocks	Sand and gravel obeying gravity.
Fluid flow	Water and lava spreading.
Leaf decay	Leaves disappearing without a nearby log.
Growth	Crops and saplings growing.
Spreading	Grass, vines, and fire spreading to other blocks.
Block forming	Snow and ice forming.
Block fading	Ice and snow melting, coral dying, fire burning out.

The common case is enabling Connections on a build world: fences and walls still join up as you place them, but nothing else moves.

Values are stored per world. New worlds inherit the defaults from world.defaults.physics-exceptions in config.yml, as does any existing world that has no stored value yet.

• Permission: buildsystem.edit.physics, the same node as the toggle itself.

Who Can Edit What

Three layers decide whether a click goes through:

1. buildsystem.edit to open the editor at all, with .self and .other if you want to distinguish own worlds from other people's.

2. The control's own node, such as buildsystem.edit.difficulty. Deny it and that one control stops responding while the rest keep working.

3. The world's own rules. A status with building disabled, or an enabled builder whitelist you are not on, blocks edits regardless of permissions. buildsystem.bypass.archive and buildsystem.bypass.builders override those.

A control you lack permission for still renders. Clicking it is refused rather than hidden, so builders can see a setting exists and ask for it rather than wondering why the menu looks different from a screenshot.
