Ore Generation

Lufe · July 10, 2020

Ok, so, I'm trying to create a new ore and generate it in the world, but, for some reason, the Minecraft is crashing everytime.

OreGeneration:

package mod.stardev.mod1.world;

import mod.stardev.mod1.lists.blocksList;
import net.minecraft.world.biome.Biome;
import net.minecraft.world.gen.GenerationStage;
import net.minecraft.world.gen.feature.Feature;
import net.minecraft.world.gen.feature.OreFeatureConfig;
import net.minecraft.world.gen.placement.CountRangeConfig;
import net.minecraft.world.gen.placement.Placement;
import net.minecraftforge.registries.ForgeRegistries;

public class OreGeneration {

    public static void setupOreGeneration() {
        for (Biome biome : ForgeRegistries.BIOMES) {
            biome.addFeature(GenerationStage.Decoration.UNDERGROUND_ORES, Biome.createDecoratedFeature(Feature.ORE, new OreFeatureConfig(OreFeatureConfig.FillerBlockType.NATURAL_STONE, blocksList.tutorial_ore.getDefaultState(), oregenConfig.tutorial_chance.get()), Placement.COUNT_RANGE, new CountRangeConfig(10, 20, 0, 100)));
        }
    }

}

oregenConfig:

package mod.stardev.mod1.world;

import net.minecraftforge.common.ForgeConfigSpec;

public class oregenConfig {

    public static ForgeConfigSpec.IntValue tutorial_chance;
    public static ForgeConfigSpec.BooleanValue generate_overworld;

    public static void init(ForgeConfigSpec.Builder server, ForgeConfigSpec.Builder client) {
        server.comment("Oregen Config");

        tutorial_chance = server
                .comment("Maximum number of ore veins of the tutorial ore that can spawn in one chunk.")
                .defineInRange("oregen.tutorial_chance", 20, 1, 1000000);

        generate_overworld = server
                .comment("Decide if you want the tutorial ore to spawn in the overworld")
                .define("oregen.generate_overworld", true);
    }
}

Looks like you're trying to setup ore generation in your constructor, which is before any registry stuff has happened, so your ore doesn't exist.

Try moving ore generation setup into FMLCommonSetupEvent

Also, you should update to 1.15.2, as 1.14.4 is going to be out of support once there is a RB for 1.16.x.

There was many new stuff in the 1.15.2 compared to 1.14.4? Also, it worked, thanks a lot.

Most of the changes from 1.14 -> 1.15 were rendering I believe.

https://gist.github.com/williewillus/30d7e3f775fe93c503bddf054ef3f93e has info on some of the 1.15 changes

I believe that CommonSetup is too early, use FMLLoadCompleteEvent .

I thought LoadComplete was supposed to be avoided for modders.

Also, DeferredWorkQueue because thread-safety is important.

The javadoc says:

Quote

* This is a mostly internal event fired to mod containers that indicates that loading is complete. Mods should not

* in general override or otherwise attempt to implement this event.

"Implement" and "Override" are specific keywords that have specific meanings in programming and if the intent was that mods should not listen for the event, then it would (or should) say "don't" use or "don't listen for" or be marked as deprecated.

A search of both the git repo and the forums return no results of anyone of any authority saying anything about the event.

I'm more than happy to be wrong, but my reading says nothing about not using the event.

Can you cite a source on that?

I'm almost positive I've seen it advised to do stuff in CommonSetup (using DeferredWorkQueue for thread safety which I forgot to mention above)

*edit: also, was just looking at Tropicraft, and it does the ore generation setup in FLMCommonSetupEvent (https://github.com/Tropicraft/Tropicraft/blob/17bcace66cbcbe1535e52a50bab48ccdd533ab9a/src/main/java/net/tropicraft/Tropicraft.java#L125)

Thanks!

Looked at the load order, for some reason I thought CommonSetup was called sooner.

    ERROR(null),
    VALIDATE(null),
    CONSTRUCT(null),
    CREATE_REGISTRIES(null),
    LOAD_REGISTRIES(null),
    COMMON_SETUP(()-> FMLCommonSetupEvent::new),
    SIDED_SETUP(SidedProvider.SIDED_SETUP_EVENT::get),
    ENQUEUE_IMC(()-> InterModEnqueueEvent::new),
    PROCESS_IMC(()-> InterModProcessEvent::new),
    COMPLETE(()-> FMLLoadCompleteEvent::new),
    DONE(null),
    GATHERDATA(ModLoader.get()::getDataGeneratorEvent);
