Built-in Lua scripting engine for server extensibility:
- YAML-based plugin descriptors (
plugin.yml) - Event listener API (
events.listen) - Command registration API (
commands.register) - Player, Server, Level, Logger, and Scheduler APIs
- Plugin management commands (
/plugins,/luaplugin)
Example plugin structure:
plugins/
example/
plugin.yml # Plugin metadata
main.lua # Plugin entry point
- Entity base class (Entity)
- Living entities (Living/Mob)
- Human entities (Human)
- Item drop entities (ItemEntity)
- AABB collision detection
- Entity attributes system (Attributes)
- Entity metadata (Metadata)
- AI behavior framework
- First-run AGPL-3.0 license display and acceptance prompt
- Acceptance state persisted to
eula.txt - Server refuses to start without license acceptance
