The error is because forge is looking for kinda server version of the mods. I don't mind helping XD, if u want to send me the all the mods you are using I can try to make it work and reply here.

now the problem is on "curios" mod LOL, are you trying to run this mods on an server world?

send the new log, without extradisks

oh ... actually, i looked better at the log, and there are two mods that as causing errors one is "rats" and the other is "extradisks", i think that the crash is due to "extradisks" and not "rats" Apparently "extradisks" is missing it's .toml file that is essencial to load the mod. can you send me where you download that mod? taking that you didn'd made it too

this mod "rats" is it yours?

The error is happening when it tries to load the Loot Table of rats:christmas_rat_gifts, can you show the code behing this loot table?

That's what i tried: "enchantment.bunchofthings.grass_walker": "Grass Walker", "enchantment.grass_walker": "Grass Walker", "bunchofthings.grass_walker": "Grass Walker", But when in an enchantment item GUI it shows "grass_walker I", "grass_walker II" and so on.

Take a look ate this section of the Docs https://mcforge.readthedocs.io/en/latest/concepts/registries/ In advance, an exemple of DeferredRegister would be something like this: DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.ITEMS, MOD_ID); RegistryObject<Block> COPPER_ORE = BLOCKS.register("copper_ore", () -> new OreBlock(...)); And when you need to access the entries (blocks) you would get them throught the BLOCKS DeferredRegister or if you need only one specific entry you would use COPPER_ORE.get() ... in your case:

Thanks, it worked ... I tried the second way, but i'll create an custom EnchantmentType to organize things better. One last thing ... how i can "rename" the enchantment in the lang file, tried several things and nothing works, the enchantment keeps showing it's registry name

But how can i do that for an enchantment book, for normal items i was able to do that by calling the function "group" as you said, but with the enchantment seems to be different.

I making some custom emchantment, and would like them to show up on an Custom ItemGroup, but i don't know where to start, i tried looking into some classes and did some google about it, but can't find anything usefull.

So, after a lot of searching and testing with some piston related code, i was able to fix the problem by creating an custom PistonTileEntity and an PistonTileEntityRenderer. 😪 Now i'm stuck in another problem. But i'll open another topic about it later.

I just did that and it worked. Thanks I also notice that the vanilla has not just the PistonBlockHead, PistonBlock and StickyPiston but also an MovingPiston ... looking into it now.

It is already on github ... link to repository I just commited some changes.

Cause i needed the head of the piston to be a different block ... or different texture. A sticky piston made from black slime ball. Nothing special about it, just for understanding how everything works. Is there an different way to achieve that?

I'm trying to create an custom sticky piston with another slime color. And i actully did make it work but having some problems. The piston itself cannot be pushed and i couldn't find out how to change that. When the piston is retracting the piston head texture changes to the default and when the retraction ends it changes back to the actual texture. Please correct me if I did something wrong or if something could be done better.

🤔🤔 Ooh, you're right. So to get the light level first the BlockState is passed as parameters. Now i get it, didn't realize that. I haven't gotten used to lamba expressions yet

I know that the function should receive ToIntFunction<BlockState>, i just named the parameter as "lightLevel" because the number returned is the light level that the block will have. And i couldn't think in a better/proper way to name it. But thanks, btw what would you recommend then?

What do you mean with "only 1 player" exactly?

Look at my answer at you previous post.

Call func_235838_a_ passing a lambda expression that returns the light level. Like this: .func_235838_a_((lightLevel) -> 10) Where 10 is the light level you expect it to have.

So, after a lot of digging around the forge/minecraft classes i managed to figure it out how the Ore Gen is working. The feature registering remains similar: public static void initGen() { Registry.register( WorldGenRegistries.field_243653_e /* Feature Registering */, ModBlocks.ADAMANTINE_ORE.getId() /* Resource Location */, Feature.field_236289_V_ /* no_surface_ore */.withConfiguration( new OreFeatureConfig( OreFeatureConfig.FillerBlockType.field_241882_a /* base_stone_overworld */, ModBlocks.ADAMANTINE_ORE.get().getDefaultState() */, 64 ) ).withPlacement(Placement.field_242910_o /* depth */ .configure( new DepthAverageConfig(12, 12) )).func_242728_a() /* spreadHorizontally */ .func_242731_b(1) /* repeat */ ); } The most trick part was adding that feature in the already configured features of an biome: public static void setupGen() { for (Map.Entry<RegistryKey<Biome>, Biome> biome : WorldGenRegistries.field_243657_i.func_239659_c_() /* Collection of Biome Entries */) { if (!biome.getValue().getCategory().equals(Biome.Category.NETHER) && !biome.getValue().getCategory().equals(Biome.Category.THEEND)) { addFeatureToBiome( biome.getValue(), GenerationStage.Decoration.UNDERGROUND_ORES, WorldGenRegistries.field_243653_e.getOrDefault(ModBlocks.ADAMANTINE_ORE.getId()) ); } } } public static void addFeatureToBiome(Biome biome, GenerationStage.Decoration decoration, ConfiguredFeature<?, ?> configuredFeature) { List<List<Supplier<ConfiguredFeature<?, ?>>>> biomeFeatures = new ArrayList<>( biome.func_242440_e().func_242498_c() /* List of Configured Features */ ); while (biomeFeatures.size() <= decoration.ordinal()) { biomeFeatures.add(Lists.newArrayList()); } List<Supplier<ConfiguredFeature<?, ?>>> features = new ArrayList<>(biomeFeatures.get(decoration.ordinal())); features.add(() -> configuredFeature); biomeFeatures.set(decoration.ordinal(), features); /* Change field_242484_f that contains the Configured Features of the Biome*/ ObfuscationReflectionHelper.setPrivateValue(BiomeGenerationSettings.class, biome.func_242440_e(), biomeFeatures, "field_242484_f"); }} Actually it seems that there's no proper way of doing this by now, since i needed to use the "setPrivateValue". It's not ideal ... but it works. Thanks a lot for the guidance.

i'll look into it, thanks. Any news i'll post here.

So at this point it isn't possible? At least not by the usual way?
