mci

Minecraft Interface - Interact with minecraft through rust

why

basically i got bored of having to do shit with clients and then manually writing classes to interact with jvm in c++, so with this project i decided to just have it automatically generate all the required mappings to every minecraft class

how to use

i don't recommend using right now.

macos

before running poly mc or what ever launcher, make sure to set the DYLD_INSERT_LIBRARIES env, example below:

DYLD_INSERT_LIBRARIES=/Users/****/dev/mci/target/debug/libmci.dylib ./polymc

progress

jni wrapper

• jclass / jobject

  • get fields
  • set fields
  • get static fields
  • set static fields
  • call methods
  • call static methods

• general QOL

  • jclass not operable with jobject (prevents you from shooting yourself)
  • easier setting & getting via traits/macros (?)

• types

  • jclass
  • jobject
  • jvalue
  • env (i)
  • jarray (ii)
  • jstring (ii)
  • others...

  information

  1. pretty much bare essentials like find class have wrapped values
  2. working on, should be done soon

  bindings / mapping generator

  • map types
    • tiny
    • yarn
  • generated output
    • classes / modules
    • get fields
    • get static fields
    • call methods
    • call static methods
    • set fields
    • set static fields
    • compilable
    • auto static detection (i)

information

i. i'll eventually work on a tool to get static fields and method names from a jar file.

MCI (root)

im not even working on it until mappings work lol

useful resources

• FabricMC/intermediary: mappings from minecraft obfuscated to yarn
• FabricMC/yarn: mappings which include names and descriptions etc.
