Regius

by FelisGamerus

Regius adds ball pythons to Minecraft, with breeding driven by a genetics system that aims to follow the real hobby.

What it does

Players breed ball pythons using genetics, so offspring carry traits inherited from their parents. The system is modeled on the reptile breeding hobby and is meant to offer a reasonable degree of realism, extending beyond what vanilla's Panda breeding covers. Hollow logs generate naturally in the world, and pythons can be given more customization through tags.

Python behavior is dynamic, including hiding and basking. The mod also adds more morphs to choose from. An in-game guidebook explains ball pythons and the breeding process, so newcomers who know little about the animals can learn what they need without leaving the game. A vanilla book combined with a piece of sphagnum moss crafts the guidebook.

Regius is a NeoForge mod for 1.21.1 and runs on client and server, so both the server and every player need it. The code is open source under the GNU General Public License v3.0 or later.
