Help with Structure / Feature Generation (1.16.3)

[jbko6]

I have a mod in which I have a "Space" dimension. I created several asteroid NBT files and I wish to have them generate naturally. I created the dimension using the new JSON system and there are spaces for adding features or structures to generate in the dimension. However, I'm really unsure as to how I can register either structures or features of my asteroids. I heard that using features for small objects is better than using structures (my biggest asteroid is 20x20x20 or so).

 

I've been unable to find any clear documentation on how feature or structure generation works in 1.16.3. Please be patient with me as I am a bit of a newbie when it comes to modding.

There probably won't be many or any actually. Either way, if you are generating a file from nbt, you should look into the vanilla source and use that as a baseline. Since you are not doing anything that might require the JigsawManager, using something like an igloo is a good start for learning how to use the Template system. Just remember, a feature of each structure should be present in all biomes while the actual structure itself should only be present in the biomes you would like it to spawn in.

 

You will need to register your features/structure using their respective forge registry before use in the JSON file itself. If you are using vanilla structures/features or just modifying the config file, you can do that purely within JSON itself.
