Solved this problem, but it's not so friendly. public class ModWorldGen { private static final CountRangeConfig copper_cfg = new CountRangeConfig(20,0,0,255); private static final int copper_veinsize = 9; public static void setupOre(){ ForgeRegistries.BIOMES.getValues().stream() .filter(biome -> biome.getCategory() != Biome.Category.THEEND) .filter(biome -> biome.getCategory() != Biome.Category.NETHER) .forEach(biome -> { biome.addFeature( GenerationStage.Decoration.UNDERGROUND_DECORATION, Feature.ORE.func_225566_b_( new OreFeatureConfig( OreFeatureConfig.FillerBlockType.NATURAL_STONE, BlockHolder.lingkiore.getDefaultState(), copper_veinsize ) ) .func_227228_a_(Placement.COUNT_RANGE.func_227446_a_(copper_cfg)) ); }); } } these func_225566_b_ func_227228_a_ func_227446_a_ are somehow difficult to understand (at least for recent days)

I have a custom OreBlock public class OreLingKi extends OreBlock { public OreLingKi() { super(Properties.create(Material.ROCK) .lightValue(1).harvestLevel(1).hardnessAndResistance(3.0f, 100.0f)); setRegistryName(Main.MODID,"lingkiore"); } } I want to how to generate it so that I can see in world? I used to do this by implements IWorldGenerator but in 1.15.1 that not work. Thanks for help?

but server no more crash...?

It works! Thank you! I modify PlayerEntity player = Minecraft.getInstance().player; to ClientPlayerEntity player = Minecraft.getInstance().player; and everything done!

tanks for your reply, actually this works well when "Single Player" mode, but when I try to start a server and a client, the server would crash. here is my packet handle void handle(Supplier<NetworkEvent.Context> context) { NetworkEvent.Context ctx = context.get(); ctx.enqueueWork(() -> { if (ctx.getDirection().getReceptionSide().isClient() && ctx.getDirection().getOriginationSide().isServer()) { PlayerEntity player = Minecraft.getInstance().player; player.getCapability(XiuXianStateProvider.XiuXianStateCap, null) .ifPresent(state -> { Capability.IStorage<IXiuXianState> storage = XiuXianStateProvider.XiuXianStateCap.getStorage(); storage.readNBT(XiuXianStateProvider.XiuXianStateCap, state, null, data); }); } }); ctx.setPacketHandled(true); } and here is how I register it ublic class NetworkLoader { private static int id=1; private final static ResourceLocation res = new ResourceLocation(Main.MODID); public static final SimpleChannel channel = NetworkRegistry.ChannelBuilder.named(res) .clientAcceptedVersions(s-> Objects.equals(s,"1")) .serverAcceptedVersions(s -> Objects.equals(s,"1")) .networkProtocolVersion(()->"1") .simpleChannel(); public static void registerMessages(){ channel.messageBuilder(XiuXianStateSyncMessage.class,id++) .decoder(XiuXianStateSyncMessage::new) .encoder(XiuXianStateSyncMessage::encode) .consumer(XiuXianStateSyncMessage::handle) .add(); } } and the server crash-report net.minecraftforge.fml.LoadingFailedException: Loading errors encountered: [ LingKi World (lingkiworld) encountered an error during the common_setup event phase §7Attempted to load class net/minecraft/client/entity/player/ClientPlayerEntity for invalid dist DEDICATED_SERVER ] at net.minecraftforge.fml.ModLoader.dispatchAndHandleError(ModLoader.java:201) ~[?:?] {re:classloading} at net.minecraftforge.fml.ModLoader.loadMods(ModLoader.java:154) ~[?:?] {re:classloading} at net.minecraftforge.fml.server.ServerModLoader.begin(ServerModLoader.java:46) ~[?:?] {re:classloading} at net.minecraft.server.dedicated.DedicatedServer.init(DedicatedServer.java:124) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:634) [?:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at java.lang.Thread.run(Thread.java:748) [?:1.8.0_221] {}

do you mean that when I want to sync data, I can post a Event above rather than a Packet?

and here is how I try to sync @SubscribeEvent public void onPlayerTracking(PlayerEvent.StartTracking event){ if(!(event.getTarget() instanceof PlayerEntity)) return; PlayerEntity player = (PlayerEntity) event.getTarget(); ServerPlayerEntity target = (ServerPlayerEntity) event.getPlayer(); if (!player.world.isRemote()) { player.getCapability(CapabilityLoader.XiuXianState, null) .ifPresent(state -> { CompoundNBT nbt = new CompoundNBT(); Capability<IXiuXianState> cap = XiuXianStateProvider.XiuXianStateCap; Capability.IStorage<IXiuXianState> storage = cap.getStorage(); nbt.put(cap.getName(), storage.writeNBT(cap, state, null)); XiuXianStateSyncMessage message = new XiuXianStateSyncMessage(nbt); NetworkLoader.channel.send(PacketDistributor.PLAYER.with(() ->target ), message); }); } }

I have create a new capability for PlayerEntity and I want to know how can I sync the data from server to client ? my Interface IXiuXianState.java package egod.mc.lingkiworld.capabilities; public interface IXiuXianState { public Realm getRealm();
