Looking for STRUCTURE_ENTITY or how to register structures in 1.19


Recommended Posts

I'm working through tutorials on modding, though the tutorial I'm following is for 1.18.   I'm cross-referencing the 1.19 docs/changelogs/pull requests to translate the 1.18 code to 1.19 as I go, but I hit a roadblock:

import net.minecraft.world.level.levelgen.feature.StructureFeature;
import net.minecraft.world.level.levelgen.feature.configurations.JigsawConfiguration;

private static final DeferredRegister<StructureFeature<?>> STRUCTURES = DeferredRegister.create(ForgeRegistries.STRUCTURE_FEATURES, MODID);

In 1.19, ForgeRegistries doesn't have a "STRUCTURE_FEATURES" member, and the JigsawConfiguration and StructureFeature classes don't exist anywhere I can find.   I don't see any obvious replacement either (like I found for other things like "ForgeRegistries.BLOCK_ENTITIES" is now "BLOCK_ENTITY_TYPES"). 

Does anyone know what the new way of registering structures is, or if some of the structure-related classes just haven't been ported to the 1.19.x code bases yet?   If you know of a good tutorial using Forge 1.19.x directly, that'd be a great bonus.

You can find the forge renames here: https://gist.github.com/SizableShrimp/882a671ff74256d150776da08c89ef72

The vanishing StructureFeatures is a Mojang change. The "equivalent" is now called StructureTypes which you can find in the vanilla Registry class.


I know very little about structures in 1.18, 1.19 or any other version so I can't help you with the rest of your question. 🙂


If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com  You should also read the support forum sticky post.
