CodeWalker.Core 1.0.2

Basic usage

YMAP

Reading a YMAP and printing the names of all entities using a nametable to resolve the hashes.

using CodeWalker.GameFiles;

List<string> nameTables = File.ReadAllLines("allnames.nametable").ToList();
nameTables.ForEach(x => JenkIndex.Ensure(x.Trim()));

YmapFile yf = new();
yf.Load(File.ReadAllBytes("test.ymap"));

yf.AllEntities.ToList().ForEach(x => Console.WriteLine(x.Name));

Result

prop_alien_egg_01
prop_alien_egg_01
prop_alien_egg_01
prop_alien_egg_01

Reading a YMAP and adding random Vectors to all entities positions and then saving it.

using CodeWalker.GameFiles;
using SharpDX;

YmapFile yf = new();
yf.Load(File.ReadAllBytes("test.ymap"));

Console.WriteLine("Old positions:");

foreach (var entity in yf.AllEntities)
{
    Console.WriteLine(entity._CEntityDef.position);
    Vector3 randomV3 = new Random().NextVector3(new Vector3(-5000), new Vector3(5000));
    entity._CEntityDef.position += randomV3;
}

Console.WriteLine("New positions:");

yf.AllEntities.ToList().ForEach(x => Console.WriteLine(x._CEntityDef.position));

File.WriteAllBytes("test_randomized.ymap", yf.Save());

Result

Old positions:
X:-1.8011817 Y:-3.3898313 Z:98.875374
X:2.8794594 Y:5.299817 Z:101.86926
X:10.3870735 Y:0.07335186 Z:102.33895
X:9.735979 Y:-13.5480585 Z:102.319534

New positions:
X:2152.357 Y:-618.8588 Z:-572.4889
X:-1108.6493 Y:-3069.503 Z:375.84045
X:-2076.676 Y:4744.5967 Z:-213.85342
X:-4593.8706 Y:-4129.6787 Z:3528.502

Reading a YMAP and exporting it as a XML (Nametables are required to export actual entities' names).

using CodeWalker.GameFiles;

YmapFile yf = new YmapFile();
string path = "test.ymap";
byte[] data = File.ReadAllBytes(path);
yf.Load(data);
string xml = MetaXml.GetXml(yf, out _);
File.WriteAllText($"{Path.GetFileNameWithoutExtension(path)}.ymap.xml", xml);

YTYP

Reading a YTYP and printing the amount of archetypes with a greater LOD distance than 73.

using CodeWalker.GameFiles;

YtypFile yt = new YtypFile();

yt.Load(File.ReadAllBytes("hei_hollywood_metadata_001_strm.ytyp"));

Console.WriteLine(yt.AllArchetypes.Count(x => x._BaseArchetypeDef.lodDist > 100));

Result

7

Reading a YTYP and setting all archetypes textureDictionary to the same and then saving it

using CodeWalker.GameFiles;

YtypFile yt = new YtypFile();

yt.Load(File.ReadAllBytes("hei_hollywood_metadata_001_strm.ytyp"));

yt.AllArchetypes.ToList().ForEach(x => x._BaseArchetypeDef.textureDictionary = JenkHash.GenHash("my_new_txd"));

File.WriteAllBytes("hei_hollywood_metadata_001_strm_modified.ytyp", yt.Save());

YDR

Reading YDR files and deleting any embedded collisions and then saving them.

using CodeWalker.GameFiles;

List<string> ydrFiles = Directory.GetFiles("ydrFiles", "*.ydr").ToList();

foreach (string ydrFile in ydrFiles)
{
    string? parentDir = Path.GetDirectoryName(ydrFile);
    string ydrFileName = Path.GetFileNameWithoutExtension(ydrFile);
    YdrFile ydr = new YdrFile();
    RpfFile.LoadResourceFile(ydr, File.ReadAllBytes(ydrFile), 165);
    if(ydr.Drawable.Bound != null)
    {
        ydr.Drawable.Bound = null;
        File.WriteAllBytes($"{parentDir}/{ydrFileName}_nocol.ydr", ydr.Save());
    }
}
