PxIgnis

Scripts are written in Lua and run on the server. A hot-reload runtime re-runs them when the ignis reload command is issued, so changes take effect within milliseconds and the server keeps running. Command registration provides a handler and permission check for each command a script defines.

The event system offers more than fifteen hooks, including player block break and player chat, and listeners can cancel an event before it completes. Regions let scripts drive mob AI inside spatial areas, with callbacks for entering, exiting, moving and death. Coroutines, persistence, UI helpers and the mc.fetch and mc.sleep functions allow sequential, asynchronous code to be written in a straight line.

The project was developed alongside Vanilla custom Roguelike, and its API reflects what that project itself needed. Required dependencies are Fabric API and Fabric Language Kotlin, and the mod is installed by placing its .jar in the server mods folder. It is released under the GNU Lesser General Public License v3.0 only, and its source code and issue tracker are public.
