How does forge load mixins?

[zly2006]

I am trying to translate fabric mods to forge so that they can be loaded by fml, but even though i added MixinConfigs in MANIFEST.MF, these mixins does not work.

My project is at https://github.com/The-Ordom-Project/OrdomalRemapper

Note that I only use tiny remapper by the fabric project, forge gradle cannot solve this problem.

I am not an expert on this, so some of this might be slightly inaccurate but...

 

The only thing forge does is include mixin in its classpath. Forge does not do anything directly to load mixins.

 

Instead mixin has a plugin for "modlauncher" https://github.com/McModLauncher/modlauncher which forge uses.

That basically lets mixin decide whether it wants to change bytecode for loaded classes.

You can read about it here: https://github.com/SpongePowered/Mixin/wiki/Mixins-on-Minecraft-Forge

 

Fabric works differently. It has its own forked version of mixin and explicitly uses that during mod loading and in its classloader.

 

Beyond that neither fabric or mixins are supported in this forum.

Even developing mixins directly for forge is not supported here (though you might get help for that in the 3rd party tools section of forge's discord?).

You need to go to wherever the mixin project provides support.
