It consolidates information from previous guides and incorporates analysis from the game's disassembly. + +## 1. Current Status & Known Issues + +A thorough review of the codebase and disassembly reveals two key facts: + +1. **The Core Implementation is Mostly Complete.** The most complex and critical parts of the dungeon editor, including the 3-type object encoding/decoding system and the ability to save objects back to the ROM, are **fully implemented**. + +2. **The Test Suite is Critically Broken.** While the core logic is in place, the automated tests that verify it are failing en masse due to two critical crashes: + * A `SIGBUS` error in the integration test setup (`MockRom::SetMockData`). + * A `SIGSEGV` error in the rendering-related unit tests. + +**Conclusion:** The immediate priority is **not** feature implementation, but **fixing the test suite** so the existing code can be validated. + +### Next Steps + +1. **Fix Test Crashes (BLOCKER)**: + * **`SIGBUS` in Integration Tests**: Investigate the `std::vector::operator=` in `MockRom::SetMockData` (`test/integration/zelda3/dungeon_editor_system_integration_test.cc`). This may be an alignment issue or a problem with test data size. + * **`SIGSEGV` in Rendering Unit Tests**: Debug the `SetUp()` method of the `DungeonObjectRenderingTests` fixture (`test/unit/zelda3/dungeon_object_rendering_tests.cc`) to find the null pointer during test scenario creation. +2. **Validate and Expand Test Coverage**: Once the suite is stable, write E2E smoke tests and expand coverage to all major user workflows. + +## 2. Architecture + +The dungeon editor is split into two main layers: the core logic that interacts with ROM data, and the UI layer that presents it to the user. + +### Core Components (Backend) + +- **`DungeonEditorSystem`**: The central coordinator for all dungeon editing operations, managing rooms, sprites, items, doors, and chests. +- **`Room`**: The main class for a dungeon room, handling the loading and saving of all its constituent parts. +- **`RoomObject`**: Contains the critical logic for encoding and decoding the three main object types. +- **`ObjectParser`**: Parses object data directly from the ROM. +- **`ObjectRenderer`**: A high-performance system for rendering dungeon objects, featuring a graphics cache and memory pool management. + +### UI Components (Frontend) + +- **`DungeonEditor`**: The main ImGui-based editor window that orchestrates all UI components. +- **`DungeonCanvasViewer`**: The canvas where the room is rendered and interacted with. +- **`DungeonObjectSelector`**: The UI panel for browsing and selecting objects to place in the room. +- **Other Panels**: Specialized panels for managing sprites, items, entrances, doors, chests, and room properties. + +## 3. ROM Internals & Data Structures + +Understanding how dungeon data is stored in the ROM is critical for the editor's functionality. This information has been cross-referenced with the `usdasm` disassembly (`bank_01.asm` and `rooms.asm`). + +### Object Encoding + +Dungeon objects are stored in one of three formats, depending on their ID. The encoding logic is implemented in `src/app/zelda3/dungeon/room_object.cc`. + +- **Type 1: Standard Objects (ID 0x00-0xFF)** + - **Format**: `xxxxxxss yyyyyyss iiiiiiii` + - **Use**: The most common objects for room geometry (walls, floors). + - **Encoding**: + ```cpp + bytes.b1 = (x_ << 2) | ((size >> 2) & 0x03); + bytes.b2 = (y_ << 2) | (size & 0x03); + bytes.b3 = static_cast(id_); + ``` + +- **Type 2: Large Coordinate Objects (ID 0x100-0x1FF)** + - **Format**: `111111xx xxxxyyyy yyiiiiii` + - **Use**: More complex objects, often interactive or part of larger structures. + - **Encoding**: + ```cpp + bytes.b1 = 0xFC | ((x_ & 0x30) >> 4); + bytes.b2 = ((x_ & 0x0F) << 4) | ((y_ & 0x3C) >> 2); + bytes.b3 = ((y_ & 0x03) << 6) | (id_ & 0x3F); + ``` + +- **Type 3: Special Objects (ID 0x200-0x27F)** + - **Format**: `xxxxxxii yyyyyyii 11111iii` (Note: The format in the ROM is more complex, this is a logical representation). + - **Use**: Special-purpose objects for critical gameplay (chests, switches, bosses). + - **Encoding**: + ```cpp + bytes.b1 = (x_ << 2) | (id_ & 0x03); + bytes.b2 = (y_ << 2) | ((id_ >> 2) & 0x03); + bytes.b3 = (id_ >> 4) & 0xFF; + ``` + +### Object Types & Examples + +- **Type 1 (IDs 0x00-0xFF)**: Basic environmental pieces. + * **Examples**: `Wall`, `Floor`, `Pillar`, `Statue`, `Bar`, `Shelf`, `Waterfall`. + +- **Type 2 (IDs 0x100-0x1FF)**: Larger, more complex structures. + * **Examples**: `Lit Torch`, `Bed`, `Spiral Stairs`, `Inter-Room Fat Stairs`, `Dam Flood Gate`, `Portrait of Mario`. + +- **Type 3 (IDs 0x200-0x27F)**: Critical gameplay elements. + * **Examples**: `Chest`, `Big Chest`, `Big Key Lock`, `Hammer Peg`, `Bombable Floor`, `Kholdstare Shell`, `Trinexx Shell`, `Agahnim's Altar`. + +### Core Data Tables in ROM + +- **`bank_01.asm`**: Contains the foundational logic for drawing dungeon objects. + - **`DrawObjects` (0x018000)**: A master set of tables that maps an object's ID to its drawing routine and data pointer. This is separated into tables for Type 1, 2, and 3 objects. + - **`LoadAndBuildRoom` (0x01873A)**: The primary routine that reads a room's header, floor, and object data, then orchestrates the entire drawing process. + +- **`rooms.asm`**: Contains the data pointers for all dungeon rooms. + - **`RoomData_ObjectDataPointers` (0x1F8000)**: A critical table of 3-byte pointers to the object data for each of the 296 rooms. This table is the link between a room ID and its list of objects, which is essential for `LoadAndBuildRoom`. + +## 4. User Interface and Usage + +### Coordinate System + +The editor manages two coordinate systems: +1. **Room Coordinates**: 16x16 tile units, as used in the ROM. +2. **Canvas Coordinates**: Pixel coordinates for rendering. + +Conversion functions are provided to translate between them, and the canvas handles scrolling and bounds-checking automatically. + +### Usage Examples + +```cpp +// Load a room +auto room_result = dungeon_editor_system_->GetRoom(0x0000); + +// Add an object +auto status = object_editor_->InsertObject(5, 5, 0x10, 0x12, 0); +// Parameters: x, y, object_type, size, layer + +// Render objects +auto result = object_renderer_->RenderObjects(objects, palette); +``` + +## 5. Testing + +### How to Run Tests + +Because the test suite is currently broken, you must use filters to run the small subset of tests that are known to pass. + +**1. Build the Tests** +```bash +# Ensure you are in the project root: /Users/scawful/Code/yaze +cmake --preset macos-dev -B build +cmake --build build --target yaze_test +``` + +**2. Run Passing Tests** +This command runs the 15 tests that are confirmed to be working: +```bash +./build/bin/yaze_test --gtest_filter="TestDungeonObjects.*:DungeonRoomTest.*" +``` + +**3. Replicate Crashing Tests** +```bash +# SIGSEGV crash in rendering tests +./build/bin/yaze_test --gtest_filter="DungeonObjectRenderingTests.*" + +# SIGBUS crash in integration tests +./build/bin/yaze_test --gtest_filter="DungeonEditorIntegrationTest.*" +``` + +## 6. Dungeon Object Reference Tables + +The following tables were generated by parsing the `DrawObjects` tables in `bank_01.asm`. + +### Type 1 Object Reference Table + +| ID (Hex) | ID (Dec) | Description
