How does forge load mixins?


Recommended Posts

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.

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
