Overview & Goals + +This document outlines a comprehensive refactoring plan for the YAZE architecture. The current structure has resulted in tight coupling between components, slow incremental build times, and architectural inconsistencies (e.g., shared libraries located within the `app/` directory). + +The primary goals of this refactoring are: + +1. **Establish a Clear, Layered Architecture**: Separate foundational libraries (`core`, `gfx`, `zelda3`) from the applications that consume them (`app`, `cli`). +2. **Improve Modularity & Maintainability**: Decompose large, monolithic libraries into smaller, single-responsibility modules. +3. **Drastically Reduce Build Times**: Minimize rebuild cascades by ensuring changes in one module do not trigger unnecessary rebuilds in unrelated components. +4. **Enable Future Development**: Create a flexible foundation for new features like alternative rendering backends (SDL3, Metal, Vulkan) and a fully-featured CLI. + +## 2. Proposed Target Architecture + +The proposed architecture organizes the codebase into two distinct layers: **Foundational Libraries** and **Applications**. + +``` +/src +├── core/ (NEW) 📖 Project model, Asar wrapper, etc. +├── gfx/ (MOVED) 🎨 Graphics engine, backends, resource management +├── zelda3/ (MOVED) 🎮 Game-specific data models and logic +├── util/ (EXISTING) 🛠️ Low-level utilities (logging, file I/O) +│ +├── app/ (REFACTORED) 🖥️ Main GUI Application +│ ├── controller.cc (MOVED) 🕹️ Main application controller +│ ├── platform/ (MOVED) 윈도우 Windowing, input, platform abstractions +│ ├── service/ (MOVED) 🤖 gRPC services for automation +│ ├── editor/ (EXISTING) 🎨 Editor implementations +│ └── gui/ (EXISTING) 🖼️ Shared ImGui widgets +│ +└── cli/ (EXISTING) ⌨️ z3ed Command-Line Tool +``` + +## 3. Detailed Refactoring Plan + +This plan will be executed in three main phases. + +### Phase 1: Create `yaze_core_lib` (Project & Asar Logic) + +This phase establishes a new, top-level library for application-agnostic project management and ROM patching logic. + +1. **Create New Directory**: Create `src/core/`. +2. **Move Files**: + * Move `src/app/core/{project.h, project.cc}` → `src/core/` + * Move `src/app/core/{asar_wrapper.h, asar_wrapper.cc}` → `src/core/` + * Move `src/app/core/features.h` → `src/core/` +3. **Update Namespace**: In the moved files, change the namespace from `yaze::core` to `yaze::project` for clarity. +4. **Create CMake Target**: In a new `src/core/CMakeLists.txt`, define the `yaze_core_lib` static library containing the moved files. This library should have minimal dependencies (e.g., `yaze_util`, `absl`). + +### Phase 2: Elevate `yaze_gfx_lib` (Graphics Engine) + +This phase decouples the graphics engine from the GUI application, turning it into a foundational, reusable library. This is critical for supporting multiple rendering backends as outlined in `docs/G2-renderer-migration-plan.md`. + +1. **Move Directory**: Move the entire `src/app/gfx/` directory to `src/gfx/`. +2. **Create CMake Target**: In a new `src/gfx/CMakeLists.txt`, define the `yaze_gfx_lib` static library. This will aggregate all graphics components (`backend`, `core`, `resource`, etc.). +3. **Update Dependencies**: The `yaze` application target will now explicitly depend on `yaze_gfx_lib`. + +### Phase 3: Streamline the `app` Layer + +This phase dissolves the ambiguous `src/app/core` directory and simplifies the application's structure. + +1. **Move Service Layer**: Move the `src/app/core/service/` directory to `src/app/service/`. This creates a clear, top-level service layer for gRPC implementations. +2. **Move Platform Code**: Move `src/app/core/{window.cc, window.h, timing.h}` into the existing `src/app/platform/` directory. This consolidates all platform-specific windowing and input code. +3. **Elevate Main Controller**: Move `src/app/core/{controller.cc, controller.h}` to `src/app/`. This highlights its role as the primary orchestrator of the GUI application. +4. **Update CMake**: + * Eliminate the `yaze_app_core_lib` target. + * Add the source files from the moved directories (`app/controller.cc`, `app/platform/window.cc`, `app/service/*.cc`, etc.) directly to the main `yaze` executable target. + +## 4. Alignment with EditorManager Refactoring + +This architectural refactoring fully supports and complements the ongoing `EditorManager` improvements detailed in `docs/H2-editor-manager-architecture.md`. + +- The `EditorManager` and its new coordinators (`UICoordinator`, `PopupManager`, `SessionCoordinator`) are clearly components of the **Application Layer**. +- By moving the foundational libraries (`core`, `gfx`) out of `src/app`, we create a clean boundary. The `EditorManager` and its helpers will reside within `src/app/editor/` and `src/app/editor/system/`, and will consume the new `yaze_core_lib` and `yaze_gfx_lib` as dependencies. +- This separation makes the `EditorManager`'s role as a UI and session coordinator even clearer, as it no longer lives alongside low-level libraries. + +## 5. Migration Checklist + +1. [ ] **Phase 1**: Create `src/core/` and move `project`, `asar_wrapper`, and `features` files. +2. [ ] **Phase 1**: Create the `yaze_core_lib` CMake target. +3.

[ ] **Phase 3**: Update the `yaze` executable's CMake target to include the moved sources and link against the new libraries. +9. [ ] **Phase 3**: Delete the now-empty `src/app/core/` directory and its `core_library.cmake` file. +10. [ ] **Verification**: Perform a clean build of all targets (`yaze`, `z3ed`, `yaze_test`) to ensure all dependencies are correctly resolved. +11. [ ] **Cleanup**: Search the codebase for any remaining `#include "app/core/..."` or `#include "app/gfx/..."` directives and update them to their new paths. + +## 6. Expected Benefits + +- **Faster Builds**: Incremental build times are expected to decrease by **40-60%** as changes will be localized to smaller libraries. +- **Improved Maintainability**: A clear, layered architecture makes the codebase easier to understand, navigate, and extend. +- **True CLI Decoupling**: The `z3ed` CLI can link against `yaze_core_lib` and `yaze_zelda3_lib` without pulling in any GUI or rendering dependencies, resulting in a smaller, more portable executable. +- **Future-Proofing**: The abstracted `gfx` library paves the way for supporting SDL3, Metal, or Vulkan backends with minimal disruption to the rest of the application. diff --git a/docs/E2-development-guide.md b/docs/E2-development-guide.md index 4f9a352d..9a98f9cc 100644 --- a/docs/E2-development-guide.md +++ b/docs/E2-development-guide.md @@ -13,6 +13,19 @@ This guide outlines the core architectural patterns, UI systems, and best practi - **Sprite Editor**: EXPERIMENTAL - **Assembly Editor**: Production ready +### Screen Editor Progress (October 2025) + +- **Title screen**: Palette and graphics group loading work, but vanilla ROM + tilemap parsing still fails.

-## Technical Architecture - -### Color/Palette System - -**Files**: `snes_color.h/cc`, `snes_palette.h/cc`, `bitmap.h/cc` - -- `SnesColor`: 15-bit SNES color container (0-31 per channel) -- `SnesPalette`: Collection of SnesColor objects -- Conversion functions: `ConvertSnesToRgb`, `ConvertRgbToSnes`, `SnesColorToImVec4` -- `SetPalette()`: Apply full palette to bitmap -- `SetPaletteWithTransparent()`: Apply sub-palette with color 0 transparent -- `BitmapMetadata`: Track source BPP, palette format, source type -- `ApplyPaletteByMetadata()`: Choose palette application method - -### Bitmap/Texture System - -**Files**: `bitmap.h/cc`, `arena.h/cc` - -- `gfx::Bitmap`: Image representation with SDL surface/texture -- `gfx::Arena`: Manages SDL resources, queues texture operations -- `UpdateSurfacePixels()`: Copy pixel data from vector to SDL surface -- Deferred texture creation/updates via command queue - -### Canvas System - -**Files**: `canvas.h/cc`, `canvas_utils.h/cc` - -- `gui::Canvas`: ImGui-based drawable canvas -- Drag, zoom, grid, palette management -- Context menu with palette help -- Live update control for palette changes - ---- - -## Lessons Learned - -### DO ✅ - -1. **Use `rom->graphics_buffer()` directly** - - Already converted to 8BPP - - No additional BPP conversion needed - - Standard throughout yaze - -2. **Dereference pointers in ROM** - - Don't read directly from pointer addresses - - Use `SnesToPc()` for SNES address conversion - - Follow pointer chains properly - -3. **Log extensively during development** - - Sample pixels from loaded sheets - - Tilemap entry counts - - VRAM addresses and tile IDs - - Helps identify issues quickly - -4. **Test with both vanilla and modded ROMs** - - Different data formats - - Different storage locations - - Auto-detection critical - -### DON'T ❌ - -1. **Assume pointer points to data** - - In vanilla ROM, title screen pointer points to CODE - - Need fixed addresses or disassembly - -2. **Modify source palettes** - - Create copies for display - - Preserve ROM data integrity - - Use `SetPaletteWithTransparent()` for rendering - -3. **Skip `UpdateSurfacePixels()`** - - Rendered data stays in vector - - Must copy to SDL surface - - Must queue texture update - -4. **Hardcode sheet IDs** - - Use GFX group tables - - Read indices from ROM - - Support dynamic configuration - ---- - -## Code Locations - -### Title Screen -- **Header**: `yaze/src/zelda3/screen/title_screen.h` -- **Implementation**: `yaze/src/zelda3/screen/title_screen.cc` -- **UI**: `yaze/src/app/editor/graphics/screen_editor.cc` (DrawTitleScreenEditor) -

---- - -## Blocked Items from Original TODO - -From the original plan, these items are **blocked** pending title screen fix: - -- [ ] ~~Identify and load correct graphics sheets for title screen~~ (DONE - sheets load correctly) -- [ ] ~~Verify tile ID to bitmap position mapping~~ (BLOCKED - need working tilemap first) -- [ ] ~~Add title_composite_bitmap_ to TitleScreen class~~ (DONE) -- [ ] ~~Implement RenderCompositeLayer() with transparency~~ (DONE) -- [ ] ~~Add Show BG1/BG2 checkboxes to screen editor UI~~ (DONE) -- [ ] **Tile painting for title screen** (BLOCKED - need working display first) -- [ ] ~~Add LoadCustomMap() for overworld~~ (DONE) -- [ ] ~~Add SaveCustomMap() for overworld~~ (DONE) -- [ ] ~~Add Load/Save Custom Map buttons~~ (DONE) -- [ ] **Tile painting for overworld map** (TODO - display works, just need painting) -- [ ] **Tile painting for dungeon maps** (TODO - display works, just need painting) - ---- - -## Recommendation - -**Stop fighting vanilla ROM format** - Focus on ZScream ROMs for now: - -1. Verify ZScream ROM display works correctly -2. Implement tile painting for ZScream format (simpler) -3. Polish overworld/dungeon editors (they work!) -4. Return to vanilla ROM format later with fresh perspective - -The vanilla ROM tilemap format is complex and poorly documented. ZScream's flat format is much easier to work with and covers the primary use case (ROM hacking). -
