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?
