Back in the good old days, Minecraft had a numeric ID system, which was later completely replaced by a namespace-based system starting with 1.13. WorldEdit, however, preserved this system for its commands, but it only works for blocks added before 1.13. This mod reworks that system by linking it to the registry ID and also adds convenient ways to find out that ID.

Disclaimer: The mod's functionality heavily differs depending on whether it is installed only on the client or on both sides

If installed only on client: Legacy IDs are used (only blocks added before 1.13 supported)
If installed on both sides or in singleplayer: Renewed registries-linked IDs are used (IDs may vary between different minecraft versions)

Why does this mod exist?

Using numeric IDs instead of Identifiers (aka ResourceLocation) in commands is much more efficient. This is especially true when filling different blocks at once or blocks with a complex BlockState. By remembering frequently used IDs, using worldedit commands will take just a matter of seconds

Features

Numeric ID is shown next to the regular ID in the tooltip on item hover (requires advanced tooltips to be shown F3 + H)
Jade Integration: Same principle as with the hover tooltip but in Jade HUD (Regsitry Name must be on in Plugin Settings)

WorldEdit: Numeric IDs Renewed
