Resourceful Creepers

Creepers in the mod drop resources when they explode, and the mod offers two modes that change how those drops are produced. Breeding works through a tier system: two creepers of the same tier bred together have a chance to produce one of the next tier. The required dependencies are Architectury API and PolyLib, and the mod is published for Fabric and Forge across six release versions, 1.18 – 1.19.2.

Settings are stored in JSON files that can be edited to adjust the mod. Textures are generated procedurally at world load, and resource packs can replace those files with custom art. Configuration files for ore blocks are generated automatically, which helps modpack builders set things up. Client and server both need the mod, and the code is under the BSD-4-Clause license, so it is not open source.
