[1.7.10] Do I have to save and read my TileEntities fields from NBTTags?

[kauan99]

Hello I have this doubt. If I have a TileEntity with a bunch of fields, and invoke markDirty() every time those fields are changed, do I still have to save those fields as NBTTags or is that data saved in some other way that doesn't need my code to explicitly do it?

[Choonster]

For a TileEntity's data to persist through reloads, it needs to be written to and then read back from NBT in the writeToNBT and readFromNBT methods. If you don't do this, the data won't be saved.

I see, thank you. I thought this was automated somehow, but that wouldn't work very well, unless there was an annotation you could add to each field and it would probably be more complicated.

 

Oh I have an idea, maybe TileEntity could be declared as abstract and have 2 abstract methods named maybe "readUserNBT" and "writeUserNBT" or whatever. and then both readFromNBT and writeToNBT base implementations would invoke their respective abstract peers?

 

Or, if that would break some part of Forge's code, then maybe instead of extending TileEntity we modders would have to extend AbstractTileEntity, and that one would be just like TileEntity (in fact, a subclass of TileEntity), but the implementations of readFromNBT and writeToNBT overriden to the way I mentioned before and with the 2 abstract methods I also mentioned being declared in it.

 

Thus, preventing us begginers from forgetting to implement the necessary persistence methods.

Hi

 

Forge is full of pitfalls like that unfortunately.

 

Like - if your client needs a copy of the field, you also need to implement packets for your TileEntity as well.

So how do I know if my client needs those packets? My tile entity has 2 slots for Item Stacks, one for input and one for output; it has a fluid tank (not implemented yet, because I still don't know how) and an RF buffer (also still no idea how to do this). Do I have to implement those packet methods? My block is basically some sort of anvil-machine.
