Save Inventories to a Text File

[Blockhead7360]

Hello! I am trying to make a plugin that saves inventories to a text file after a certain amount of time (incase you would need to revert if an inventory is lost).

 

Here is what I have so far:

public static void saveInv(){
	for (Object o : MinecraftServer.getServer().getConfigurationManager().playerEntityList){
		EntityPlayer p = (EntityPlayer) o;

		Date date = new Date();
		SimpleDateFormat f = new SimpleDateFormat("MM-dd-yyyy HH-mm-ss");
		File file = new File("InventoryStorageFolder/" + p.getGameProfile().getName() + " - " + f.format(date) + ".txt");
		if (!file.exists())
			try {
				file.createNewFile();
			} catch (IOException e) {
				e.printStackTrace();
			}
		PrintWriter writer = null;
		try {
			writer = new PrintWriter(file);
		} catch (FileNotFoundException e1) {
			e1.printStackTrace();
		}


		for (ItemStack s : p.inventory.mainInventory){
			if (s == null) continue;
			int id = Item.getIdFromItem(s.getItem());

			if (!s.hasTagCompound()){
				writer.println(Integer.toString(id) + "*" + s.stackSize);
			}else
			writer.println(Integer.toString(id) + "*" +  s.stackSize + "*" + s.getTagCompound().toString());
		}
		writer.close();

	}
}

 

I have a few questions, though.

 

1. How do I get the data number of the item (like for vanilla dye or wool: 0-15)?

2. I'm pretty sure most mods, like Tinkers Construct for example, store their item information into NBT tags. If I convert the tags to a string and put it in the file, how do I convert it back to NBT?

 

If I'm doing anything wrong or if this could be done more easily, please let me know!

 

Thanks, Blockhead7360.

What do you mean?

Why not save the players' inventory to NBT?
