Thread: Where Are "Clipped" Landscapes Fetched From?

Didn't know how to describe it, so just put clipped landscapes, basically the gzipped files used here:

Code:

public static void load() {
		long startup = System.currentTimeMillis();
		System.out.println("Loading region clipping...");
		try {
			File f = new File("./data/cache/map_index.dat");
			
			byte[] buffer = new byte[(int) f.length()];
			DataInputStream dis = new DataInputStream(new FileInputStream(f));
			dis.readFully(buffer);
			dis.close();
			ByteStream in = new ByteStream(buffer);
					
			int size = in.readUnsignedShort();
			
			regions = new RegionClipping[size];
			int[] mapRegionIds = new int[size];
			int[] mapTerrains = new int[size];
			int[] mapLandscapes = new int[size];			
			for (int i = 0; i < size; i++) {
				mapRegionIds[i] = in.readUnsignedShort();			
				mapTerrains[i] = in.readUnsignedShort();
				mapLandscapes[i] = in.readUnsignedShort();
			}
			
			for (int i = 0; i < size; i++) {
				regions[i] = new RegionClipping(mapRegionIds[i]);
			}
			
			int amount = 0;
			
			for (int i = 0; i < size; i++) {
				byte[] file1 = getBuffer(new File("./data/cache/map/" + mapLandscapes[i] + ".gz"));
				byte[] file2 = getBuffer(new File("./data/cache/map/" + mapTerrains[i] + ".gz"));
				if (file1 == null || file2 == null)
					continue;
				loadMaps(mapRegionIds[i], new ByteStream(file1), new ByteStream(file2), i);
				amount++;
			}
			System.out.println("Loaded " + amount + " region clipping" + (amount != 1 ? "s" : "") + " in " + (System.currentTimeMillis() - startup) + "ms");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	private static void loadMaps(int regionId, ByteStream landscapes, ByteStream terrains, int index) {
		try {
			int absX = (regionId >> 8) * 64;
			int absY = (regionId & 0xff) * 64;
			int[][][] someArray = new int[4][64][64];
			for (int i = 0; i < 4; i++) {
				for (int i2 = 0; i2 < 64; i2++) {
					for (int i3 = 0; i3 < 64; i3++) {
						
						do {
							if (terrains.offset + 1 > terrains.buffer.length)
								break;
							int l1 = terrains.getUByte();
							if (l1 == 0) {
								break;
							} else if (l1 == 1) {
								terrains.skip(1);
								break;
							} else if (l1 <= 49) {
								terrains.skip(1);
							} else if (l1 <= 81) {
								someArray[i][i2][i3] = l1 - 49;
							} else {
								someArray[i][i2][i3] = l1 - 81;
							}
						} while(true);
					}
				}
			}
			for (int i = 0; i < 4; i++) {
				for (int i2 = 0; i2 < 64; i2++) {
					for (int i3 = 0; i3 < 64; i3++) {
						if ((someArray[i][i2][i3] & 1) == 1) {
							int height = i;
							if ((someArray[1][i2][i3] & 2) == 2) {
								height--;
							}
							if (height >= 0 && height <= 3) {
								addClipping(absX + i2, absY + i3, height, 0x200000);
							}
						}
					}
				}
			}
			
			int objectId = -1;
			int value;
			while ((value = landscapes.getUSmart()) != 0) {
				System.out.println("value=" + value);
				objectId += value;
				int location = 0;
				int increment;
				while ((increment = landscapes.getUSmart()) != 0) {
					System.out.println("increment=" + increment);
					location += increment - 1;
					System.out.println("location=" + location);
					int localY = (location & 0x3f);
					int localX = (location >> 6 & 0x3f);
					int height = location >> 12;
					int objectData = landscapes.getUByte();
					int type = objectData >> 2;
					int direction = objectData & 3;
					int x = absX + localX;
					int y = absY + localY;
					if (localX < 0 || localX >= 64 || localY < 0 || localY >= 64) {
						continue;
					}
					if ((someArray[1][localX][localY] & 2) == 2) {
						height--;
					}
					if (height >= 0 && height <= 3) {
						addObject(objectId, x, y, height, type, direction);
						System.out.println("rendered object: " + objectId + "; x=" + x + "; y=" + y + "; z=" + height);
					}
				}

Thought it was this:

Code:

public void extractMapFiles(String directory) throws IOException {
		File folder = new File(directory);
		if (folder.mkdir()) {
			System.out.println("Created new directory: " + directory);
		}
		for (int i = 0; i < mainCacheFile[4].size(); i++) {
			System.out.println("Extracting map: " + i);
			byte[] map = mainCacheFile[4].get(i);
			ByteArrayOutputStream bout = new ByteArrayOutputStream();
			DeflaterOutputStream os = new GZIPOutputStream(bout);
			try {
				os.write(map);
				os.finish();
				DataOutputStream output = new DataOutputStream(new FileOutputStream(directory + i + ".gz"));
				output.write(bout.toByteArray());
			} finally {
				os.close();
			}
		}
	}

But it wasn't as the reading was wrong, used the 317 map gzipped files (from the clipping release) and it worked fine, which is how I know that the dumped files are wrong.

Anyone know which files I need to dump?
