[1.10.2] Question about syncing tile entity data

That depends:

Does the client ever need to know this information?

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Then sync the data.

Override getUpdatePacket and getUpdateTag()

 

getUpdatePacket will return a new package with the contents returned from getUpdateTag, where you write all the TE's information in it.  You can get away with just using the same nbt that's saved to disk, as long as there isn't a ton of data the client doesn't need.

I tried that but it doesn't work. Heres my code:

public class TileCrystalFurnace extends TileEntity implements ITickable {

private static ArrayList<Block> hotBlocks = new ArrayList();

static {
	hotBlocks.add(Blocks.LAVA);
	hotBlocks.add(Blocks.FLOWING_LAVA);
	hotBlocks.add(Block.getBlockFromName("magma"));
}

private ItemStackHandler inventory = new ItemStackHandler(2) {
	@Override
	protected void onContentsChanged(int slot) {
		TileCrystalFurnace.this.markDirty();
	}

	@Override
	protected int getStackLimit(int slot, ItemStack stack) {
		if (slot == 0) {
			if (stack.getItem() == Items.DIAMOND) return super.getStackLimit(slot, stack);
		} else if (slot == 1) {
			if (stack.getItem() == Item.getItemFromBlock(Blocks.GLASS)) return super.getStackLimit(slot, stack);
		}
		return 0;
	}

};

private FluidTank crystalTank = new FluidTank(Fluid.BUCKET_VOLUME * 2) {
	@Override
	protected void onContentsChanged() {
		TileCrystalFurnace.this.markDirty();
	}
};

public boolean isHeated;
public boolean isMelting;
public int meltTime = 0;

public TileCrystalFurnace() {
	crystalTank.setCanFill(false);
}

@Override
public void update() {
	isHeated = worldObj.getBlockState(pos.add(0, -1, 0)) != null && hotBlocks.contains(worldObj.getBlockState(pos.add(0, -1, 0)).getBlock());

	if (worldObj.isRemote) return;

	if (isHeated && !isMelting && inventory.extractItem(0, 1, true) != null && inventory.extractItem(1, 3, true) != null && inventory.extractItem(1, 3, true).stackSize == 3 && crystalTank.fillInternal(new FluidStack(EnchantedAura.liquidCrystal, 500), false) == 500) {
		inventory.extractItem(0, 1, false);
		inventory.extractItem(1, 3, false);
		isMelting = true;
		meltTime = 400;
		this.markDirty();
	}

	if (isMelting && meltTime == 0) {
		isMelting = false;
		crystalTank.fillInternal(new FluidStack(EnchantedAura.liquidCrystal, 500), true);
		this.markDirty();
	}

	if (isMelting && isHeated) {
		meltTime--;
		this.markDirty();
	}

}

@Override
public void readFromNBT(NBTTagCompound compound) {
	super.readFromNBT(compound);

	inventory.deserializeNBT(compound.getCompoundTag("inventory"));
	crystalTank.readFromNBT(compound.getCompoundTag("crystalTank"));

	meltTime = compound.getInteger("meltTime");
	isMelting = compound.getBoolean("isMelting");
}

@Override
public NBTTagCompound writeToNBT(NBTTagCompound compound) {
	compound.setTag("inventory", inventory.serializeNBT());
	compound.setTag("crystalTank", crystalTank.writeToNBT(new NBTTagCompound()));

	compound.setInteger("meltTime", meltTime);
	compound.setBoolean("isMelting", isMelting);

	return super.writeToNBT(compound);
}

@Override
public boolean hasCapability(Capability<?> capability, EnumFacing facing) {
	if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY || capability == CapabilityFluidHandler.FLUID_HANDLER_CAPABILITY)
		return true;
	return super.hasCapability(capability, facing);
}

@Override
public <T> T getCapability(Capability<T> capability, EnumFacing facing) {
	if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY)
		return (T) inventory;
	else if (capability == CapabilityFluidHandler.FLUID_HANDLER_CAPABILITY)
		return (T) crystalTank;
	return super.getCapability(capability, facing);
}

@Override
public final NBTTagCompound getUpdateTag() {
	return this.writeToNBT(new NBTTagCompound());
}

@Override
public SPacketUpdateTileEntity getUpdatePacket() {
	return new SPacketUpdateTileEntity(this.getPos(), 1, this.getUpdateTag());
}

}

 

My GUI never shows the progress bar moving, or liquid entering the tank. It does show the items disappearing however thats probably because the container syncs items.

1) Mark dirty says "this needs to be saved to disk" not "send this to the client."

2) I believe the method you want is now called

worldObj.markAndNotifyBlock(pos, chunk, iblockstate, newState, flags);

3) The client isn't updating its own values on its end because you did

if (worldObj.isRemote) return;

(you can safely remove that for the most part)

If the only reason for marking an update is to sync tile entity data to the client for rendering purposes, then worldObj.notifyBlockUpdate(pos, oldState, newState, flags) looks to be a better option.  markAndNotifyBlock() works - it calls notifyBlockUpdate() - but it also notifies the block's neighbours of a blockstate change, and may cause some comparator recalculation - extra unnecessary server load if you're just syncing TE data.

Thanks desht.

 

I have trouble finding that method because the 1.7 name was "markBlockForUpdate" or similar, so I type "mark..." and autocompletion gives me results that don't include that one.
