[1.12.2] TileEntity doesn't sync to client.

[TheAwesomeGem]

The value cookTime on the client TileEntity is always 0. What am I doing wrong?

You never set cookTime on the client. Look at the furnace container.

Yeah but Furnace Container uses IInventory and setField to update it.

[TheAwesomeGem]

Just now, diesieben07 said:

... so?

There is no such option for ItemHandler.

[TheAwesomeGem]

Just now, diesieben07 said:

Why not? Also, IItemHandler has nothing to do with this.

Can I implement IInventory whilst also using IItemHandler. The way the furnace updates GUI is using the IInventory fields.

[TheAwesomeGem]

Just now, diesieben07 said:

You could, in theory, but it makes no sense.

 

Yes, but you are not using IInventory.

Exactly. So I cannot use setFields. I though marking the block dirty after setting the cookTime would automatically update it due to the update packet function. But it does not.

You don't need to.

 

Please don't use that way. You should keep network traffic as low as possible. Syncing cookTime every tick to every player within render distance even if they are not looking at the GUI is completely overkill.

 

What way do you suggest? How to sync TileEntity GUI with the TileEntity?

Already told you: Look at ContainerFurnace.

 

Aaah you mean detectAndSendChanges method? And that works without IInventory and the fields? Nice.

Why would it not? Have you bothered to actually look at the code? ...

 

I might have overlooked it. Will try it out and see if it works.
