Valid Worlds Option

The validworlds option restricts where a structure can be created.

This is a premium feature.

Basic example

options:
  validworlds:
    worlds:
      - "world_nether"
    notify:
      actionbar: "<red>You cannot create this structure in this world."

In this example, the structure can only be created in world_nether.

Fields

Field	Type	Description
worlds	List	Worlds where the structure is allowed.
notify	Notify section	Message sent when the player tries to create it in the wrong world.

Multiple worlds

options:
  validworlds:
    worlds:
      - "world"
      - "world_nether"
      - "custom_resource_world"
    notify:
      message: "<red>This structure cannot be created here."

Recommended use

Use validworlds for:

• Nether-only structures;
• End-only altars;
• resource world generators;
• spawn-only utility structures;
• preventing abuse in survival worlds.

Important note

World names must match the exact folder/world name used by the server.

For example, these are different:

world_nether
World_Nether
