I created and registered several placed features through code (not json based)

Now I need to add them to vanilla biomes, for this I created biome tags for the biomes the features are supposed to generate in.

 

the biome tag is created at:

/data/example_mod/tags/worldgen/biome/has_feature/large_mushroom.json

the biome tag is referenced in my code like this:

public static final TagKey<Biome> HAS_FEATURE_LARGE_MUSHROOM = getTagKey("has_feature/large_mushroom");
/* more tags created similar */

private static TagKey<Biome> getTagKey(String id) {
     return TagKey.create(Registry.BIOME_REGISTRY, new ResourceLocation("example_mod", id));
}

my BiomeLoadingEvent (registered to the forge eventbus)

public static void onBiomeLoad(final BiomeLoadingEvent event) {
    Biome biome = ForgeRegistries.BIOMES.getValue(event.getName());
    boolean isCorrectBiome = ForgeRegistries.BIOMES.tags().getTag(HAS_FEATURE_LARGE_MUSHROOM).contains(biome); //always false
}

 

It looks like the biome tags are not filled/validated when the BiomeLoadingEvent is fired?

but using the command `/locatebiome #example_mod:has_feature/large_mushroom` works without problems

 

Am I missing something, or is there another way of adding my features to biomes without hardcoding them?

 

So, I created an example repository with my problem, might be easier to understand then my explanation

https://github.com/tristankechlo/BiomeTagsForBiomeLoadingEvent

The main issue is that `BiomeLoadingEvent` intercepts the biome before it is loaded, so it wouldn't be in the registry. Additionally, I believe that the event is loaded before tags are populated, so you wouldn't be able to write anything anyways. In my opinion, I would just update to 1.19 with biome modifiers and use those since they have no issues supporting tags.
