PyFish (python)

A mod that allows you to execute python scripts or to make your own mods using python.

It has a “Minecraft” API that allows you to set blocks, summon entities, listen to events, etc. and since the last update you can also register items, blocks, creative tabs, tags, etc. under the namespace you want.

You can do whatever you want from adding blocks and crafts to your modpack to connecting your LLM API key to your server.

The user don’t have to have anything installed for Python to work.
This mod has GraalPy (a java Python) and pip integrated in its jar.

You can install every python package that is pure python you want in your mod.

Some Native packages are recoded in Java and included in PyFish. Native libs built-in now :
requests, sqlite3, asyncio, logging, pathlib, and websocket

You have to put your scripts in <your_mc_instance>/pyfish/<your_folder>/scripts/ (the name of “your_folder” will be the namespace used to register items, etc.) or in <your_mc_instance>/pyfish/scripts/ (if you put in pyfish/scripts it will register under pyfish’s namespace), they are executed automatically.

You can also make .jar mods and also .pyz (100% python) mods.
