Writing/reading from NBT

[Garan105]

How necessary is it to have the writeToNBT and readFromNBT in an interfaceable Tile Entity? I've been looking at the code for TileEntityFurnace and noticed that it has those functions. It looks like it's using them to store the information when the game is closed, is this true?

eh, interfaceable? not sure what you mean by that. furnace uses NBT to save current progress and inventory. it's not just when game closes, it's also used when chunks are unloaded (the loading from NBT, not certain about saving, it's imo more frequent).
