snaking last update on sept 29 2024 so i m currently trying to figure out why the pyopengl 3 12 test suite is failing there s a particular test that looks for vbo memory leakage and it looks loosely

that we ve removed an entry point that pip 22 0 uses from python 3 12 that means that you need to install pip from get pip py on ubuntu lts python3 12 however even with that done and tox supposedly

pythonic typing for there exists some plugin that provides an adapter for x written by mike on june 18 2023 in snaking last update on june 18 2023 so starting to think about a pyopengl 4 x release which would be first to drop python 2 7 support so the first one where type hints can be used to declare metadata for type coercion vs the current nonstandard type declarations the first big question

nov 12 2022 in snaking last update on nov 12 2022 in pycraft i figured out the potions with custom effects the problem being that bukkit s potioneffecttype doesn t actually implement the keyed interface but instead has its own values call so needs a whole special handler the code for creating potion with custom effects looks like await potion_of night_vision gopher s gruel type fast_digging

lets you write very close to python code in the minecraft chat window to perform magic that s written in python code on the backend i thought maybe a few demos showing what you can do with the code
