How to initialise Mixins without the plugin because 1.20.1 is broken lol

(RECOMMEND USING INTELLJ ALONGSIDE MCREATOR WHEN USING MIXINS, MAKES LIFE WAY EASIER LIKE SERIOUSLY.)

So you're here because you want to make a strong mod, or you just want to override Minecraft behaviour and methods. So I'll show you how to initialise Mixins without ForgeMixins.

First, To initialise Mixins, you'll have to make some changes to your mod's build.gradle

1. depending on your version, it'll be different

   if you have buildscript in it

   do this

   buildscript {    repositories {        maven { url = 'https://maven.minecraftforge.net/' }        maven { url = 'https://repo.spongepowered.org/repository/maven-public/' }    }    dependencies {        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '5.1.+', changing: true        classpath group: 'org.spongepowered', name: 'mixingradle', version: '0.7-SNAPSHOT'    } }
   
   apply plugin: 'net.minecraftforge.gradle'
   apply plugin: 'org.spongepowered.mixin'
   
   If you don't and are using the plugins DSL, do this instead:

2. plugins {    id 'eclipse'    id 'maven-publish'    id 'net.minecraftforge.gradle' version '5.1.+'    id 'org.spongepowered.mixin' version '0.7.+' }
   
   Then place this anywhere in the build.gradle
   
   mixin {    add sourceSets.main, "modid.refmap.json"    config "modid.mixins.json" }
   
   now put this in dependencies
   
   annotationProcessor 'org.spongepowered:mixin:0.8.5:processor'
   
   now go to resources (mod files obviously) and create a json file called modid.mixins.json
   
   {    "required": true,    "package": "your.package.name.mixin",    "compatibilityLevel": "JAVA_8",    "refmap": "modid.refmap.json",    "mixins": [    ],    "client": [    ],    "minVersion": "0.8" }
   
   change your.package.name.mixin to net.mcreator.modid.mixin
   
   then you go to net > mcreator > modid then you create a folder in there called mixin
   
   example: setRemoved immunity
   
   @Mixin(Entity.class) public class Immunity {    private void setRemoved(Entity.RemovalReason p146876, CallbackInfo ci) {                Entity entity = (Entity)(Object)this;                if (entity instanceof YourEntity) {                        ci.cancel();                }    } }
   
   as for the imports, use Intellj, I want you guys to have better lives.
   
   This code targets the Entity class then injects on setRemoved, if it's your entity then it'll cancel setRemoved
   
   {    "required": true,    "package": "your.package.name.mixin",    "compatibilityLevel": "JAVA_8",    "refmap": "modid.refmap.json",    "mixins": [        "Immunity"    ],    "client": [    ],    "minVersion": "0.8" }
   
   name the class Immunity btw (name the file Immunity), then add it onto the modid.mixins.json like how I did up here.
   
   And you're good to go! Remember that you have to keep practicing and one day, you might become an MS Mod Author!
