Forge mixins is a plugin that allows other java plugins to define mixins that their mod elements generate and register. This can be done by including a list of strings in the generatable element of the mod element, which is then picked up by this plugin and included in the list of registered mixins. The plugin does not add any new features by itself.
How does the plugin pick up mixins from mod elements?
In order to have your mod elements' mixins recognised by this plugin and included in the mixin list, your generatable element needs to include a public List<String> with the name mixins. This should be initialized with the mixins' class names in the generatable element's constructor.
![]()
The plugin also adds the "Mixin" mod element, which is a copy of the "Custom element" mod element, but is detected as a mixin. You can use this element to manually code new mixins you want to use.

Alternatively, you can use the procedural mixin mod element to inject a procedure into vanilla code if you do not know java. Beaware that procedural mixins are prone to crashes and breaking between minecraft version updates due to changes in the code.

This is a java plugin and therefore requires java plugins to be enabled.

Can you make a tutorial on this? I 100% don't get it. It also from what I'm seeing looks like you have to edit the original classes code each time you update it anyways, at that point, just add in your mixins each time yknow? I just don't understand it, nothing on you..
NerdyPuzzle, Please help with this question, I beg you, if it doesn’t bother you - "How can I add BlockEntity to Vanilla FarmBlock using the "Forge mixins support" plugin". I wanted to add NBT to FarmBlock to track the FarmBlock custom parameter while playing in the overlay

You can do that after you export the jar
