[1.16.1]Player Capability values reset when login.

[kyazuki]

The values saved in playerdata file.

However, the values aren't imported when login.

How do I fix?

 

Main:

public static final ResourceLocation CAP_RESOURCE = new ResourceLocation(MODID, "capabilities");

public TestMod() {
  FMLJavaModLoadingContext.get().getModEventBus().addListener(TestMod::onFMLCommonSetup);
}

@SubscribeEvent
public static void onFMLCommonSetup(FMLCommonSetupEvent event) {
  CapabilityManager.INSTANCE.register(IMyCapability.class, new MyCapabilityStorage(), () -> new MyCapability(2.0f));
}

@SubscribeEvent
public static void attachCapability(AttachCapabilitiesEvent<Entity> event) {
  if (!(event.getObject() instanceof PlayerEntity)) return;

  event.addCapability(CAP_RESOURCE, new MyCapabilityProvider());
}

 

Provider:

public class MyCapabilityProvider implements ICapabilitySerializable<INBT> {
  @CapabilityInject(IMyCapability.class)
  public static final Capability<IMyCapability> CAP = null;

  private LazyOptional<IMyCapability> instance = LazyOptional.of(CAP::getDefaultInstance);

  @Nonnull
  @Override
  public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nullable Direction side) {
    return CAP.orEmpty(cap, instance);
  }

  @Override
  public INBT serializeNBT() {
    return (INBT) CAP.getStorage().writeNBT(CAP, instance.orElseThrow(() -> new IllegalArgumentException("at serialize")), null);
  }

  @Override
  public void deserializeNBT(INBT nbt) {
    CAP.getStorage().readNBT(CAP, instance.orElseThrow(() -> new IllegalArgumentException("at deserialize")), null, nbt);
  }
}

 

Storage:

public class MyCapabilityStorage implements Capability.IStorage<IMyCapability> {
  @Override
  public INBT writeNBT(Capability<IMyCapability> capability, IMyCapability instance, Direction side) {
    CompoundNBT tag = new CompoundNBT();
    tag.putFloat("cap1", instance.getCap1());
    tag.putFloat("cap2", instance.getCap2());
    tag.putFloat("cap3", instance.getCap3());
    return tag;
  }

  @Override
  public void readNBT(Capability<IMyCapability> capability, IMyCapability instance, Direction side, INBT nbt) {
    CompoundNBT tag = (CompoundNBT) nbt;
    instance.setCap1(tag.getFloat("cap1"));
    instance.setCap2(tag.getFloat("cap2"));
    instance.setCap3(tag.getFloat("cap3"));
  }
}

I checked by NBTExplorer.

[kyazuki]

My cap value is synced player max health.

It's reset every time player join the world.

[kyazuki]

"scale" is the value.

The players max health is set to "scale" multiplied by 20.

I noticed PlayerEntity.distanceWalkModified reset when login.

How do I get statics correctly on 1.16.1?
