Saving variables in tile entities after quitting minecraft?

[Zeretul4]

Hey everyone, I'm working on a furnace that will have a fuel buffer and it's working like I want it to. It'll burn coal when theres room to store energy and then it'll use that energy to cook items. The only problem is that whenever i save and quit then come back, the buffer is reset to 0. Is there a way to save that number? Thanks a lot!

You are looking for NBT Tag Coupounds.  Two good sources of information on how to use them are here:

I tried using nbt data before after looking up the problem, but it wasn't working for me. Heres the code I have, I don't have a clue as to why it's not working. This is just a method in my tile entity class.

 

@Override
        public void readFromNBT(NBTTagCompound tagCompound) {
        	// working code for setting itemstacks, commenting this out breaks the furnace so i know this is being called
                super.readFromNBT(tagCompound);
                NBTTagList tagList = tagCompound.getTagList("Inventory");
                for (int i = 0; i < tagList.tagCount(); i++) {
                        NBTTagCompound tag = (NBTTagCompound) tagList.tagAt(i);
                        byte slot = tag.getByte("Slot");
                        if (slot >= 0 && slot < inv.length) {
                                inv[slot] = ItemStack.loadItemStackFromNBT(tag);
                        }
                } //(ends here)
                
                fuelLevel = tagCompound.getInteger("Fuel"); // reading it isn't working
                //fuelLevel = 50; // me even trying to brute force set it and still not working
        }

you need to use packets so the gui can update.

Ah, thanks so much! None of the tutorials i found about nbt mentioned this.

But it isn't the GUI thats going wrong, its the saving, but mabye Packets will help, but how do I use them/what should I do with them?

The gui is client side, all information must be serverside.

If the client is doing something to change the info inn a tileEntity you must let the server know!

To let the server kniw this you use packets

 

Take a look on the tutorials on the forgewiki as well as google for packet tutorials.
