libMCdev
A development library mainly intended for me (AnOpenSauceDev) and my mods
This mod is designed for mod-developers. Chances are, they have already baked this mod in via Jar-In-Jar. If not, you can download it from here. (libMCdev on its own will take priority over include-ed versions of this mod.)
Features
- An OS-grabbing tool, that offers a more detailed view on OS information, especially on Linux.
- A primitive media API, built off of Minecraft's own image system, that can be applied to just about anything.
- A persistent variable API, useful for storing small blocks of data across worlds (and servers).
- A debug system, that allows you to only execute code when running in development environments.
There's probably more, but a lot changes frequently. Speaking of that, backwards compatability is not guaranteed. The closest thing to "compatibility" ensured is whatever Methane calls. If you for some reason do use libMCdev, let me know, and I can partially accomodate for that.
As always, if you want to work with this, you should read the docs here.
