I'm trying to attach a capability to a chunk, but I can't do it, I did it the following way and it doesn't work, what's wrong? How do I solve it? public class BloodDensityProvider implements ICapabilityProvider, INBTSerializable<CompoundTag> { public static Capability<TitanBloodDensity> TITAN_BLOOD_HANDLER = CapabilityManager.get(new CapabilityToken<>() {}); private TitanBloodDensity density; private final LazyOptional<TitanBloodDensity> optional = LazyOptional.of(this::getDensity); public TitanBloodDensity getDensity() { if (density == null) density = new TitanBloodDensity(); return density; } @Override public @NotNull <T> LazyOptional<T> getCapability(@NotNull Capability<T> cap, @Nullable Direction side) { if (cap == TITAN_BLOOD_HANDLER) return optional.cast(); else return LazyOptional.empty(); } @Override public CompoundTag serializeNBT() { CompoundTag nbt = new CompoundTag(); nbt.putInt("density", getDensity().getAmount()); return nbt; } @Override public void deserializeNBT(CompoundTag nbt) { getDensity().set(nbt.getInt("density")); } } public class TitanBloodDensity implements ITitanBloodHandler { private int bloodAmount = 0; @Override public int getAmount() { return bloodAmount; } @Override public void sub(int amount) { bloodAmount -= amount; } @Override public void add(int amount) { bloodAmount += amount; } @Override public void set(int value) { bloodAmount = value; } } @Mod.EventBusSubscriber(modid = MODID) public class ModEvent { [...] @SubscribeEvent public void onAttachChunkCapabilitiesChunk(AttachCapabilitiesEvent<LevelChunk> event) { if (!event.getObject().getCapability(TITAN_BLOOD_HANDLER).isPresent()) { event.addCapability(new ResourceLocation(MODID, "proprieties/blood_density"), new BloodDensityProvider()); } } [...] @SubscribeEvent public static void onRegisterCapabilities(RegisterCapabilitiesEvent event) { event.register(PlayerGCTXProvider.class); event.register(BloodDensityProvider.class); } [...] } public class SprayerBlockEntity extends FluidHandlerBlockEntity implements MenuProvider { [...] public boolean trySpray() { if (tank.getFluidAmount() >= BUCKET_VOLUME) { assert level != null; LazyOptional<TitanBloodDensity> capability = level.getChunkAt(getBlockPos()) .getCapability(TITAN_BLOOD_HANDLER); capability.ifPresent(handler -> { handler.add(100); tank.drain(BUCKET_VOLUME, IFluidHandler.FluidAction.EXECUTE); }); System.out.println(capability.isPresent()); // false return capability.isPresent(); } return false; } } I did the same method for the player and it worked, why doesn't it work with chunk?
