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

Custom data pack structures with jigsaws in 1.19

(Last updated: 1.19)

This is a direct conversion for 1.19, of my original guide for 1.18.2.
For the sake of continuity i will show everything from groundup again. I would show the new 1.19 sections in different colour, but github doesn't allow that 😐

This is technically a shameless rip/edit of Misode's guide (go give that beautiful man a heart under his guides) that shows the traditional use of newly implemented custom structure system. I myself want to tackle the jigsaw aspect a bit, hence i'm making my own guice based on his. I will show how to create a data pack that adds custom structures to the world that also utilize jigsaw blocks. So treat this as a basic jigsaw guide in world generation. There is a download for the datapack at the end of this guide.

**Always leave the world and rejoin to apply the new changes! Because traditional /reload or `/datapack disable & enabl
