Add-ons

PlaceholderAPI (optional—placeholders are automatically disabled if not installed)

Placeholders

• %worldmanager_worldname% - World name
• %worldmanager_worldtime% - World time (e.g., 7:00 PM)
• %worldmanager_worldweather% - World weather (e.g., sun, rain)
• %worldmanager_worldplayers% - Number of players in the world
• %worldmanager_worlddifficulty% - World difficulty

Changelog

• External generator plugins - e.g., VoidGen: /world create <name> custom VoidGen overworld
• Void worlds now have a Bedrock block at the spawn point - no more falling into the void
• Automatic detection of new world storage formats (including Paper 26.2’s Dimensions structure) — also loads and manages worlds created by other plugins or the server software itself
• Deletion confirmation with timeout — /world delete prompts {name} confirm, which automatically expires after a configurable time
• /world debug - diagnostic command that outputs the server’s actual available world API to the console
• Configuration split into two files: config.yml (technical settings) and messages.yml (all text, freely customizable/translatable)
