[1.17.1] Error when creating custom biome

Posted November 10, 20213 yr

I've been trying to implement a custom biome and I've run across an error that crashes my game when trying to create a new world and disallows me to enter any existing worlds.

I followed this tutorial for making biomes (with one or two changes to class names and method names).

My code looks like this

Spoiler

public static final ResourceKey<Biome> MAPLE_BIOME = ResourceKey.create(Registry.BIOME_REGISTRY, new ResourceLocation(GooseMod.MODID, "maple_forest"));

private void setup(final FMLCommonSetupEvent event) {
   	event.enqueueWork(() -> {
        ModWorldGeneration.registerConfiguredFeatures();
        BiomeManager.addAdditionalOverworldBiomes(MAPLE_BIOME);
    });
}

@SubscribeEvent(priority = EventPriority.HIGH)
  public static void onBiomeLoad(BiomeLoadingEvent event) {
  ResourceKey<Biome> eventBiomeKey = ResourceKey.create(Registry.BIOME_REGISTRY, event.getName());
  if (eventBiomeKey == MAPLE_BIOME)
  {
    event.getGeneration().getFeatures(GenerationStep.Decoration.VEGETAL_DECORATION).add(() -> ORANGE_MAPLE);
    event.getGeneration().getFeatures(GenerationStep.Decoration.VEGETAL_DECORATION).add(() -> RED_MAPLE);
    event.getGeneration().getFeatures(GenerationStep.Decoration.VEGETAL_DECORATION).add(() -> YELLOW_MAPLE);
  }
}
}

and the exception is this

What exactly am I missing? I understand that the tutorial is for 1.16, but I couldn't find anything for 1.17 and so far it hasn't been that difficult to implement it into my project. Did they add a step in 1.17?

why on earth are you creating a ResourceKey in BiomeLoadingEvent, you should use the Name you get from the Event and the Location of the ResourceKey (you can get it from ResourceKey#location) instead also is your FMLCommonSetupEvent fierd?

My FMLCommonSetupEvent is being fired, I've debugged the method call but nothing seems out of the ordinary.

It's what it said to do here. Again it was the only resource I had on this.

yeah that's correct but you should call ResourceKey#get and not ResourceKey#create

sorry my mistake, did not see that the tutorial is for 1.16 and ResourceKey#get in 1.17 has been removed
i would recommend you to use the ResourceLocations instead,
one location you can get from the Event the other from your ResourceKey via ResourceKey#location

if you add your Biome to the Overworld via BiomeManager#addAdditionalOverworldBiomes,
you need to register your Biome via DeferredRegister or RegistryEvent

unfortunately a json only Biome does not work in this case

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
