## 🚀 Quick Start
|
||||||
|
|
||||||
|
### Linux/Unix Systems
|
||||||
|
|
||||||
|
**Extract single .z file:**
|
||||||
|
```bash
|
||||||
|
cd RR3CommunityServer/Tools
|
||||||
|
chmod +x extract_z_asset.sh
|
||||||
|
./extract_z_asset.sh /path/to/sprites_0.etc.dds.z
|
||||||
|
```
|
||||||
|
|
||||||
|
**Batch extract entire directory:**
|
||||||
|
```bash
|
||||||
|
chmod +x batch_extract_z_assets.sh
|
||||||
|
./batch_extract_z_assets.sh /path/to/assets/directory
|
||||||
|
```
|
||||||
|
|
||||||
|
**Pack file to .z format:**
|
||||||
|
```bash
|
||||||
|
chmod +x pack_z_asset.sh
|
||||||
|
./pack_z_asset.sh sprites_0.etc.dds
|
||||||
|
```
|
||||||
|
|
||||||
|
### Windows Systems
|
||||||
|
|
||||||
|
**PowerShell extraction:**
|
||||||
|
```powershell
|
||||||
|
cd RR3CommunityServer\Tools
|
||||||
|
.\extract_z_asset.ps1 -InputFile "C:\path\to\sprites_0.etc.dds.z"
|
||||||
|
```
|
||||||
|
|
||||||
|
**With custom output directory:**
|
||||||
|
```powershell
|
||||||
|
.\extract_z_asset.ps1 -InputFile "C:\assets\file.z" -OutputDir "C:\extracted"
|
||||||
|
```
|
||||||
|
|
||||||
|

||||||
|
builder.Services.AddScoped<AssetExtractionService>();
|
||||||
|
```

## 🔬 Technical Details
|
||||||
|
|
||||||
|
### .z File Format
|
||||||
|
|
||||||
|
RR3 uses ZLIB-compressed files with `.z` extension:
|
||||||
|
|
||||||
|
1. **Magic Bytes**: `0x78` followed by `0x9C`, `0xDA`, or `0x01`
|
||||||
|
2. **Compression**: Standard ZLIB/Deflate algorithm (level 9)
|
||||||
|
3. **Format**: Can contain multiple ZLIB blocks concatenated
|
||||||
|
4. **Content**: Usually DDS textures (ETC2 for Android, BC3 for PC)
|
||||||
|
|
||||||
|
### Extraction Algorithm
|
||||||
|
|
||||||
|
```
|
||||||
|
1. Read file into byte array
|
||||||
|
2. Scan for ZLIB magic bytes (0x78 0x9C/0xDA/0x01)
|
||||||
|
3. Attempt decompression from each position
|
||||||
|
4. Concatenate all successfully decompressed blocks
|
||||||
|
5. Write output file
|
||||||
|
```
|
||||||
|
|
||||||
|
### Performance
|
||||||
|
|
||||||
|
- **Single file extraction**: ~50-200ms per file (depending on size)
|
||||||
|
- **Batch extraction**: Parallel processing available
|
||||||
|
- **Compression ratio**: Typically 60-80% for textures
|
||||||
|
- **Memory**: Loads entire file into memory (ensure sufficient RAM for large files)
|
||||||
|
|

## 📦 Integration with Custom Content System
|
||||||
|
|
||||||
|
### Auto-Extract Uploaded Custom Content
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
public async Task<IActionResult> UploadCustomTexture(IFormFile file)
|
||||||
|
{
|
||||||
|
// Save uploaded .z file
|
||||||
|
var savedPath = await SaveUploadedFile(file);
|
||||||
|
|
||||||
|
// Auto-extract if it's a .z file
|
||||||
|
if (file.FileName.EndsWith(".z"))
|
||||||
|
{
|
||||||
|
var extractedPath = await _assetExtraction.ExtractZFileAsync(savedPath);
|
||||||
|
|
||||||
|
// Process extracted DDS/texture
|
||||||
|
await ProcessTexture(extractedPath);
|
||||||
|
}
|
||||||
|
|
||||||
|
return Ok();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Custom Car/Track Workflow
|
||||||
|
|
||||||
|
```
|
||||||
|
1. User uploads custom car skin (PNG)
|
||||||
|
2. Server converts PNG → DDS (using ImageMagick/Compressonator)
|
||||||
|
3. Server packs DDS → .z using AssetExtractionService
|
||||||
|
4. Server stores .z file in database
|
||||||
|
5. APK downloads .z file when user selects custom car
|
||||||
|
6. APK extracts .z → DDS on device
|
||||||
|
7. Game renders custom texture
|
||||||
|
```
|
||||||

## 🧪 Testing
|
||||||
|
|
||||||
|
### Test Extraction
|
||||||
|
```bash
|
||||||
|
# Test single file
|
||||||
|
./extract_z_asset.sh test_assets/sprites_0.etc.dds.z
|
||||||
|
|
||||||
|
# Verify output
|
||||||
|
file test_assets/sprites_0.etc.dds # Should show: DDS image data
|
||||||
|
|
||||||
|
# Test round-trip
|
||||||
|
./pack_z_asset.sh test_assets/sprites_0.etc.dds
|
||||||
|
./extract_z_asset.sh test_assets/sprites_0.etc.dds.z test_assets/sprites_0_roundtrip.etc.dds
|
||||||
|
diff test_assets/sprites_0.etc.dds test_assets/sprites_0_roundtrip.etc.dds
|
||||||
|
```
|
||||||
|
|
||||||
|
### Test API Endpoints
|
||||||
|
```bash
|
||||||
|
# Start server
|
||||||
|
cd RR3CommunityServer/RR3CommunityServer
|
||||||
|
dotnet run
|
||||||
|
|
||||||
|
# Test extraction endpoint
|
||||||
|
curl -X POST http://localhost:5143/api/AssetManagement/extract \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"fileName": "sprites_0.etc.dds.z"}'
|
||||||
|
|
||||||
|
# Test batch extraction
|
||||||
|
curl -X POST http://localhost:5143/api/AssetManagement/batch-extract \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"inputDirectory": "raw_assets"}'
|
||||||
|
|
||||||
|
# List assets
|
||||||
|
curl http://localhost:5143/api/AssetManagement/list
|
||||||
|
```
|
||||||
|
|
||||||

||||||

|
||||||
|
## 🔒 Security Considerations
|
||||||
|
|
||||||
|
### Path Traversal Protection
|
||||||
|
|
||||||
|
The API endpoints use `Path.Combine` with a base path to prevent directory traversal attacks:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
var filePath = Path.Combine(_assetBasePath, request.FileName);
|
||||||
|
// request.FileName = "../../../etc/passwd" → blocked by Path.Combine
|
||||||
|
```
|
||||||
|
|
||||||
|
### File Size Limits
|
||||||
|
|
||||||
|
Consider adding file size limits in production:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
[RequestSizeLimit(100_000_000)] // 100 MB max
|
||||||
|
public async Task<IActionResult> ExtractAsset([FromBody] ExtractRequest request)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Authentication
|
||||||
|
|
||||||
|
Add authentication middleware for production:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
[Authorize(Roles = "Admin,Moderator")]
|
||||||
|
public class AssetManagementController : ControllerBase
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 🐛 Troubleshooting
|
||||||
|
|
||||||
|
### "No valid ZLIB blocks found"
|
||||||
|
|
||||||
|
**Cause**: File is not ZLIB compressed or is corrupted.
|
||||||
|
|
||||||
|
**Fix**: Verify file with hex editor (should start with `78 9C` or `78 DA`).
|
||||||
|
|
||||||
|
### "Permission denied"
|
||||||
|
|
||||||
|
**Linux/Unix**:
|
||||||
|
```bash
|
||||||
|
chmod +x *.sh
|
||||||
|
sudo chown $USER:$USER /path/to/assets
|
||||||
|
```
|
||||||
|
|
||||||
|
**Windows**: Run PowerShell as Administrator.
|
||||||
|
|
||||||
|
### "Python 3 not found"
|
||||||
|
|
||||||
|
**Linux**:
|
||||||
|
```bash
|
||||||
|
# Ubuntu/Debian
|
||||||
|
sudo apt install python3
|
||||||
|
|
||||||
|
# RedHat/CentOS
|
||||||
|
sudo yum install python3
|
||||||
|
```
|
||||||
|
|
||||||
|
**Windows**: Install from [python.org](https://www.python.org/)
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 📊 File Format Reference
|
||||||
|
|
||||||
|
### DDS (DirectDraw Surface)
|
||||||
|
|
||||||
|
Standard texture format used by RR3:
|
||||||
|
|
||||||
|
- **Android**: ETC2_RGBA compression
|
||||||
|
- **PC**: BC3 (DXT5) compression
|
||||||
|
- **Header**: 128 bytes (DDS magic + DDS_HEADER)
|
||||||
|
- **Mipmaps**: Usually included for LOD
|
||||||
|
|
||||||
|
### Conversion Tools
|
||||||
|
|
||||||
|
For converting between formats:
|
||||||
|
|
||||||
|
- **PNG → DDS**: AMD Compressonator CLI, ImageMagick
|
||||||
|
- **DDS → PNG**: Noesis, GIMP with DDS plugin
|
||||||
|
- **DDS compression**: `-fd ETC2_RGBA` (Android), `-fd BC3` (PC)
|
||||||
|

||||||

|
## 🎯 Next Steps
|
||||||
|
|
||||||
|
1. **✅ COMPLETED**: Cross-platform extraction scripts
|
||||||
|
2. **✅ COMPLETED**: C# service for server-side extraction
|
||||||
|
3. **✅ COMPLETED**: API endpoints for asset management
|
||||||
|
4. **TODO**: Image conversion pipeline (PNG ↔ DDS)
|
||||||
|
5. **TODO**: Asset validation (verify DDS headers, check corruption)
|
||||||
|
6. **TODO**: Asset CDN integration (serve extracted assets)
|
||||||
|
7. **TODO**: Custom content moderation system
