[1.14] Custom Structures

[Draco18s]

Anyone know how these work? I've been poking at the code and trying a few things, and while I have gotten the game to call hasStartAt(...) (and a bit further, such as having MyStructure.Start get init'd), I haven't been able to determine that any blocks are actually placed in the world.

 

I'm trying to work out how the system functions so I can help Lawremi update Custom Ore Generation, which relies on being able to place ore blocks from code (not structure files) as its has its own systems for determining what goes where, but at the moment I'd be happy to just get any of these structure functions that have a reference to World (addComponentParts, handleDataMarker, whatever) get called at all.

I've been experimenting myself... to no luck however (this is my registry file, works, but still don't know how to get the structure to spawn or how to add it to the locate command)

@ObjectHolder(VisionaryMod.modid)

public class VisionaryStructures {

    public static final Structure<NoFeatureConfig> INFERNALFORTRESS = new InfernalFortressStructure(NoFeatureConfig::deserialize);

 

    @SubscribeEvent

    public static void registerStructures(IForgeRegistry<Feature<?>> event) {

        VisionaryUtil.basic(event)

                .add("infernal_fortress", INFERNALFORTRESS);

    }

}

Yeah, I've gotten that much myself.

Though I'll note that Structure<?> and Feature<?> work just fine for the object holder annotation (and as far as I can tell, both use the same registry; i.e. RegistryEvent.Register<Feature<?>>).

 

I've also gotten features working just fine, eg:

Ah ha, I figured something out.

 

Structures need to be sent to biomes as both a structure and a feature or they won't generate. Still more work to do, but that part finally starts making sense.
