Starting in 1.20, the Material class has completely disappeared and has been replaced with a series of properties that are chained to BlockBehavior.Properties.of. This list exists so you can easily figure out which propeties to use to replace the old materials.

Every Material here gives its default MapColor (previously known as MaterialColor), regardless of if it had one or not. It also defines which properties to use to replicate the exact behavior used previously.

The very bottom of this file defines the more complicated replacements to certain material properties.

• AIR - No MapColor, replaceable
• STRUCTURAL_AIR - No MapColor, replaceable
• PORTAL - No MapColor, PushReaction.BLOCK
• CLOTH_DECORATION - MapColor.WOOL, ignitedByLava

What are mixins?

Mixins are a way to inject code or change the minecraft source code directly and should be use with caution. If you can do a PR to Forge or use an event, try those first. If all else fails, then mixins may be a good option to look into. Here are some resources for mixins:

• Mixin Official Docs: https://github.com/SpongePowered/Mixin/wiki
• Mixin Javadocs: https://jenkins.liteloader.com/view/Other/job/Mixin/javadoc/index.html
• Mixin Cheatsheet: https://github.com/2xsaiko/mixin-cheatsheet
• MixinExtras (Adds some powerful compatiable mixin options!): https://github.com/LlamaLad7/MixinExtras

Now, I'll be honest, the official mixin doc is kind of terrible to learn from for most people. It's extremely dense and and really only helps people who already knows in-depth bytecode and stuff. But most modders aren't like that and just wants to do small stuff lol. But I'll give you the run-down here. There's a few kinds of mixins that you will encounter quite often.

Overview of changes

• net.minecraftforge.fml.common.IWorldGenerator -> net.minecraft.world.gen.feature.Feature
  • No longer needed. I think it should be removed by forge, as it has been superseded by vanilla functionality. See below.
• net.minecraft.world.gen.feature.WorldGenerator -> net.minecraft.world.gen.feature.Feature
  • This would also be the most common replacement of Forge's IWorldGenerator. This should be the solution for anything smaller than a chunk.
  • Except the 8 blocks offset. This is not a thing anymore. Population now works just like any normal person would expect.
  • Position of features is controlled by instances of net.minecraft.world.gen.placement.BasePlacement instead of by the feature itself.
• net.minecraft.world.gen.MapGenBase -> net.minecraft.world.gen.carver.IWorldCarver
• This is now finally exposed to mods in a useful way. As it was mostly hidden from modders before, not eveyone may know what it is, so it will be explained later. Generates caves a
