Generate a dedicated OneBlock world.
For example, using Multiverse-Core:
/mv create OneBlock normal -g Oneblock
Initialize the OneBlock area:
/ob set
/ob set 500
/ob set <offset> <x> <y> <z> [world]
Players can teleport to their island by entering:
/ob join
or simply /ob


use: /ob Progress_bar level
You can specify the color of the progress bar for each level separately! In the blocks.yml file, the second line (after the line with the name of the level)
You can append _by_position to any placeholder to get information about the island at your current location instead of your own island.
Examples:
- %OB_lvl_by_position% - Shows the level of the island at your current location.
- %OB_owner_name_by_position% - Shows the owner name of the island at your current location.
- %OB_visits_by_position% - Shows the visit count of the island at your current location.
- %OB_break_on_this_lvl_by_position% - Shows blocks broken on the island at your current location.
This is especially useful when visiting other players' islands or when you want to display information about a specific island based on location rather than the player viewing the placeholder.
/ob progress_bar settext %OB_lvl% lvl now. Need block to next lvl %OB_need_to_lvl_up%.

Blocks system rework:
- blocks.yml now supports weighted entries via optional weight field (defaults to 1). Higher weight = more likely to appear.
- Old blocks.yml is automatically backed up as blocks.yml.bak before migration.
Chest system rework:
- Added vanilla loot table support for natural chest generation. Use chest: <name> in blocks.yml and define <name>: namespace:path in chests.yml.
- Full backward compatibility with legacy item-list chests preserved.
Code improvements:
- Refactored internal codebase, fixed bugs and typos.
Command changes: /ob chest:
- /ob chest <name> set <namespaced_key> — assign a vanilla loot table to a chest alias.
- /ob chest <name> edit — open a GUI to edit the contents of a legacy item-list chest.
