Thread: Packed Spawns Dumper

Accidentally deleted my unpackedSpawnsList.txt and needed to write a packed spawns dumper, so I'd like to share it.
I'm not sure which other revisions use this spawning system so I marked it as 718.

Code:

public static void dumpPackedSpawns() throws IOException {
		File dumpFile, packedSpawnsFolder;
		File[] packedFiles;
		BufferedWriter writer;

		dumpFile = new File("data/npcs/unpackedSpawnsList.txt");
		if (dumpFile.exists())
			dumpFile.delete();
		
		packedSpawnsFolder = new File("data/npcs/packedSpawns/");
		packedFiles = packedSpawnsFolder.listFiles();
		
		writer = new BufferedWriter(new FileWriter(dumpFile, false));
		
		for (File file : packedFiles) {
			System.out.println("Dumping data for region " + file.getName().split("\\.")[0] + ".");
			
			RandomAccessFile regionFile = new RandomAccessFile(file, "r");
			FileChannel regionFileChannel = regionFile.getChannel();
			ByteBuffer buffer = regionFileChannel.map(MapMode.READ_ONLY, 0, regionFileChannel.size());
			
			while (buffer.hasRemaining()) {
				int npcId = buffer.getShort() & 0xffff;
				int plane = buffer.get() & 0xff;
				int x = buffer.getShort() & 0xffff;
				int y = buffer.getShort() & 0xffff;
				boolean hashExtraInformation = buffer.get() == 1;
				int mapAreaNameHash = -1;
				boolean canBeAttackFromOutOfArea = true;
				if (hashExtraInformation) {
					mapAreaNameHash = buffer.getInt();
					canBeAttackFromOutOfArea = buffer.get() == 1;
				}

				writer.write( npcId + " - " + x + " " + y + " " + plane);
				if (hashExtraInformation)
					writer.write(" " + mapAreaNameHash + " " + canBeAttackFromOutOfArea);
				writer.newLine();
			}
			
			regionFileChannel.close();
			regionFile.close();
		}

		writer.close();
	}

Note: This will replace your unpackedSpawnsList.txt if you have one!
