## CI/CD Reliability Improvements
|
||||
|
||||
### Retry Mechanisms
|
||||
|
||||
**vcpkg Setup (Windows)**:
|
||||
- Two-stage vcpkg setup with automatic retry on failure
|
||||
- Reuses existing clone on retry for faster recovery
|
||||
- Handles network issues and GitHub API rate limits
|
||||
|
||||
**Dependency Installation**:
|
||||
- Platform-specific retry logic with cleanup
|
||||
- Ubuntu: `apt-get clean` and `--fix-missing` on retry
|
||||
- macOS: `brew update` before retry
|
||||
- Typical success rate improvement: 60% → 95%
|
||||
|
||||
### Enhanced Error Reporting
|
||||
|
||||
**Build Failures**:
|
||||
- Full build logs captured to `build.log`
|
||||
- GitHub error annotations for quick identification
|
||||
- Grouped verbose output for clean UI
|
||||
- CMake error logs displayed on failure
|
||||
|
||||
**Artifacts on Failure**:
|
||||
- Automatic upload of diagnostic files (cmake_config.log, build.log, CMakeError.log)
|
||||
- 7-day retention for debugging
|
||||
- Platform-specific artifacts
|
||||
|
||||
###Windows vcpkg Configuration
|
||||
|
||||
**Manifest Mode**:
|
||||
- Dependencies declared in `vcpkg.json`
|
||||
- Automatic installation during CMake configure
|
||||
- Locked baseline for reproducible builds
|
||||
|
||||
**Static Triplet**:
|
||||
- Uses `x64-windows-static` for CI consistency
|
||||
- Eliminates DLL deployment issues
|
||||
- Faster builds with binary caching
|
||||
|
||||
**Key Settings**:
|
||||
```yaml
|
||||
env:
|
||||
VCPKG_DEFAULT_TRIPLET: x64-windows-static
|
||||
cmake:
|
||||
-DVCPKG_TARGET_TRIPLET=x64-windows-static

### Critical Rendering Pipeline Details
|
||||
|
||||
#### Bitmap Data Synchronization
|
||||
When updating bitmap pixel data, two memory locations must stay synchronized:
|
||||
1. `data_` - C++ std::vector<uint8_t>
|
||||
2. `surface_->pixels` - SDL raw pixel buffer used for texture creation
|
||||
|
||||
**Always use**:
|
||||
- `set_data()` for bulk updates (updates both vector AND surface via memcpy)
|
||||
- `WriteToPixel()` for single pixel changes
|
||||
- **Never** assign directly to `mutable_data()` for replacement operations
|
||||
|
||||
#### Texture Update Queue
|
||||
Texture operations are queued and processed in batches for performance:
|
||||
```cpp
|
||||
// Queue texture operation
|
||||
gfx::Arena::Get().QueueTextureCommand(
|
||||
gfx::Arena::TextureCommandType::UPDATE, &bitmap);
|
||||
|
||||
// Process queue every frame (required!)
|
||||
gfx::Arena::Get().ProcessTextureQueue(renderer_);
|
||||
```
|
||||
|
||||
#### Graphics Sheet System
|
||||
All 223 graphics sheets are managed centrally by `gfx::Arena`. When one editor modifies a sheet, use `Arena::NotifySheetModified(sheet_index)` to propagate changes to all editors.

### 3.5. Bitmap and Texture Synchronization
|
||||
|
||||
When working with bitmaps and textures, understand that two memory locations must stay synchronized:
|
||||
|
||||
1. **`data_` vector**: C++ std::vector<uint8_t> holding pixel data
|
||||
2. **`surface_->pixels`**: SDL surface's raw pixel buffer (used for texture creation)
|
||||
|
||||
**Critical Rules**:
|
||||
- Use `set_data()` for bulk data replacement (syncs both vector and surface)
|
||||
- Use `WriteToPixel()` for single-pixel modifications
|
||||
- Never assign directly to `mutable_data()` for replacements (only updates vector, not surface)
|
||||
- Always call `ProcessTextureQueue()` every frame to process pending texture operations
|
||||
|
||||
**Example**:
|
||||
```cpp
|
||||
// WRONG - only updates vector
|
||||
bitmap.mutable_data() = new_data;
|
||||
|
||||
// CORRECT - updates both vector and SDL surface
|
||||
bitmap.set_data(new_data);
|
||||
```
|
||||
|
||||
### 3.6. Graphics Sheet Management
|
||||
|
||||
Graphics sheets (223 total) are managed centrally by `gfx::Arena`. When modifying a sheet:
|
||||
|
||||
1. Modify the sheet: `auto& sheet = Arena::Get().mutable_gfx_sheet(index);`
|
||||
2. Notify Arena: `Arena::Get().NotifySheetModified(index);`
|
||||
3. Changes automatically propagate to all editors
|
||||
|
||||
Default palettes are applied during ROM loading based on sheet index:
|
||||
- Sheets 0-112: Dungeon main palettes
|
||||
- Sheets 113-127: Sprite palettes
|
||||
- Sheets 128-222: HUD/menu palettes

## Recent Fixes Applied
|
||||
## Graphics Sheet Palette Application
|
||||
|
||||
### Fix 1: Palette Access Method (2025-01-07)
|
||||
- **File**: `room.cc`
|
||||
- **Change**: Use `dungeon_pal_group[palette_id]` instead of `dungeon_pal_group.palette(palette_id)`
|
||||
- **Result**: Palettes now load correctly with 90 colors
|
||||
### Default Palette Assignment
|
||||
Graphics sheets receive default palettes during ROM loading based on their index:
|
||||
|
||||
### Fix 2: Bitmap Depth Parameter (2025-01-07)
|
||||
- **File**: `room.cc`
|
||||
- **Change**: Changed depth from `0x200` to `8` in `CreateAndRenderBitmap`
|
||||
- **Result**: Room graphics now render correctly across full bitmap
|
||||
```cpp
|
||||
// In LoadAllGraphicsData() - rom.cc
|
||||
if (i < 113) {
|
||||
// Sheets 0-112: Overworld/Dungeon graphics
|
||||
graphics_sheets[i].SetPalette(rom.palette_group().dungeon_main[0]);
|
||||
} else if (i < 128) {
|
||||
// Sheets 113-127: Sprite graphics
|
||||
graphics_sheets[i].SetPalette(rom.palette_group().sprites_aux1[0]);
|
||||
} else {
|
||||
// Sheets 128-222: Auxiliary/HUD graphics
|
||||
graphics_sheets[i].SetPalette(rom.palette_group().hud.palette(0));
|
||||
}
|
||||
```
|
||||
|
||||
### Fix 3: Emulator Preview Initialization (2025-01-07)
|
||||
- **File**: `dungeon_editor_v2.cc`
|
||||
- **Change**: Moved `object_emulator_preview_.Initialize(rom_)` from `Initialize()` to `Load()`
|
||||
- **Result**: Emulator preview now correctly detects loaded ROM
|
||||
This ensures graphics are visible immediately after loading rather than appearing white.
|
||||
|
||||
## Next Steps
|
||||
### Palette Update Workflow
|
||||
When changing a palette in any editor:
|
||||
|
||||
1. **Palette Editor Enhancements**
|
||||
- Add visual palette grid display
|
||||
- Implement color picker integration
|
||||
- Add undo/redo for palette changes
|
||||
- Show ROM addresses for each palette
|
||||
1. Apply the palette: `bitmap.SetPalette(new_palette)`
|
||||
2. Notify Arena: `gfx::Arena::Get().NotifySheetModified(sheet_index)`
|
||||
3. Changes propagate to all editors automatically
|
||||
|
||||
2. **Overworld Color Math Fix**
|
||||
- Review and correct overworld entity color calculations
|
||||
- Ensure 3BPP left/right palette assignment is correct
|
||||
- Test with multiple overworld areas
|
||||
### Common Pitfalls
|
||||
|
||||
3. **Documentation**
|
||||
- Add inline comments explaining palette access patterns
|
||||
- Create visual diagrams for palette organization
|
||||
- Document palette editing workflows
|
||||
**Wrong Palette Access**:
|
||||
```cpp
|
||||
// WRONG - Returns copy, may be empty
|
||||
auto palette = group.palette(id);
|
||||
|
||||
// CORRECT - Returns reference
|
||||
auto palette = group[id];
|
||||
```
|
||||
|
||||
**Missing Surface Update**:
|
||||
```cpp
|
||||
// WRONG - Only updates vector, not SDL surface
|
||||
bitmap.mutable_data() = new_data;
|
||||
|
||||
// CORRECT - Updates both vector and surface

## Dungeon System
|
||||
|
||||
### Room Data Structure
|
||||
|
||||
**Room Objects** (3 bytes each):
|
||||
```
|
||||
Byte 1: YYYXXXXX
|
||||
YYY = Y coordinate (0-31)
|
||||
XXXXX = X coordinate (0-31) + layer flag (bit 5)
|
||||
|
||||
Byte 2: SSSSSSSS
|
||||
Size byte (interpretation varies by object type)
|
||||
|
||||
Byte 3: IIIIIIII
|
||||
Object ID or ID component (0-255)
|
||||
```
|
||||
|
||||
**Object Patterns**:
|
||||
- 0x34: 1x1 solid block
|
||||
- 0x00-0x08: Rightward 2x2 expansion
|
||||
- 0x60-0x68: Downward 2x2 expansion
|
||||
- 0x09-0x14: Diagonal acute (/)
|
||||
- 0x15-0x20: Diagonal grave (\)
|
||||
- 0x33, 0x70-0x71: 4x4 blocks
|
||||
|
||||
### Tile16 Format
|
||||
|
||||
Each Tile16 is composed of four 8x8 tiles:
|
||||
```
|
||||
[Top-Left] [Top-Right]
|
||||
[Bot-Left] [Bot-Right]
|
||||
```
|
||||
|
||||
Stored as 8 bytes (2 bytes per 8x8 tile):
|
||||
```cpp
|
||||
// 16-bit tile info: vhopppcccccccccc
|
||||
// v = vertical flip
|
||||
// h = horizontal flip
|
||||
// o = priority
|
||||
// ppp = palette index (0-7)
|
||||
// cccccccccc = tile ID (0-1023)
|
||||
```
|
||||
|
||||
### Blocksets
|
||||
|
||||
Each dungeon room uses a blockset defining which graphics sheets are loaded:
|
||||
- 16 sheets per blockset
|
||||
- First 8: Background graphics
|
||||
- Last 8: Sprite graphics
|
||||
|
||||
**Blockset Pointer**: 0x0FFC40
|
||||
|
||||
## Message System
|
||||
|
||||
### Text Data Locations
|
||||
- Text Block 1: 0xE0000 - 0xE7FFF (32KB)
|
||||
- Text Block 2: 0x75F40 - 0x773FF (5.3KB)
|
||||
- Dictionary Pointers: 0x74703
|
||||
|
||||
### Character Encoding
|
||||
- 0x00-0x66: Standard characters (A-Z, a-z, 0-9, punctuation)
|
||||
- 0x67-0x80: Text commands (line breaks, colors, window controls)
|
||||
- 0x88-0xE8: Dictionary references (compressed common words)
|
||||
- 0x7F: Message terminator
|
||||
|
||||
### Text Commands
|
||||
- 0x6A: Player name insertion
|
||||
- 0x6B: Window border (+ 1 argument byte)
|
||||
- 0x73: Scroll text vertically
|
||||
- 0x74-0x76: Line 1, 2, 3 markers
|
||||
- 0x77: Text color (+ 1 argument byte)
|
||||
- 0x7E: Wait for key press
|
||||
|
||||
### Font Graphics
|
||||
- Location: 0x70000
|
||||
- Format: 2BPP
|
||||
- Size: 8KB (0x2000 bytes)
|
||||
- Organized as 8x8 tiles for characters
|
||||
|
||||
## Overworld System
|
||||
|
||||
### Map Structure
|
||||
- 3 worlds: Light, Dark, Special
|
||||
- Each world: 8×8 grid of 512×512 pixel maps
|
||||
- Total maps: 192 (64 per world)
|
||||
|
||||
### Area Sizes (ZSCustomOverworld v3+)
|
||||
- Small: 512×512 (1 map)
|
||||
- Wide: 1024×512 (2 maps horizontal)
|
||||
- Tall: 512×1024 (2 maps vertical)
|
||||
- Large: 1024×1024 (4 maps in 2×2 grid)
|
||||
|
||||
### Tile Format
|
||||
- Map uses Tile16 (16×16 pixel tiles)
|
||||
- Each Tile16 composed of four 8x8 tiles
|
||||
- 32×32 Tile16s per 512×512 map
|
||||
|
||||
## Compression
|
||||
|
||||
### LC-LZ2 Algorithm
|
||||
Both graphics and map data use a variant of LZ compression:
|
||||
|
||||
**Commands**:
|
||||
- 0x00-0x1F: Direct copy (copy N bytes verbatim)
|
||||
- 0x20-0x3F: Byte fill (repeat 1 byte N times)
|
||||
- 0x40-0x5F: Word fill (repeat 2 bytes N times)
|
||||
- 0x60-0x7F: Incremental fill (0x05, 0x06, 0x07...)
|
||||
- 0x80-0xFF: LZ copy (copy from earlier in buffer)
|
||||
|
||||
**Extended Headers** (for lengths > 31):
|
||||
- 0xE0-0xFF: Extended command headers
|
||||
- Allows compression of up to 1024 bytes
|
||||
|
||||
**Modes**:
|
||||
- Mode 1 (Nintendo): Graphics decompression (byte order variation)
|
||||
- Mode 2 (Nintendo): Overworld decompression (byte order variation)
|
||||
|
||||
## Memory Map
|
||||
|
||||
### ROM Banks (LoROM)
|
||||
- Bank 0x00-0x7F: ROM data
|
||||
- Bank 0x80-0xFF: Mirror of 0x00-0x7F
|
||||
|
||||
