## Overview
|
||||
|
||||
The Dungeon Editor uses a modern card-based architecture (DungeonEditorV2) with self-contained room rendering. Each room manages its own background buffers independently.
|
||||
|
||||
### Key Features
|
||||
- ✅ **Visual room editing** with 512x512 canvas per room
|
||||
- ✅ **Object position visualization** - Colored outlines showing object placement
|
||||
- ✅ **Per-room settings** - BG1/BG2 visibility, layer types
|
||||
- ✅ **Live palette editing** - Immediate visual feedback
|
||||
- ✅ **Flexible docking** - EditorCard system for custom layouts
|
||||
- ✅ **Overworld integration** - Double-click entrances to open rooms
|
||||
|
||||
### Architecture Principles
|
||||
1. **Self-Contained Rooms** - Each room owns its bitmaps and palettes
|
||||
2. **Correct Loading Order** - LoadRoomGraphics → LoadObjects → RenderRoomGraphics
|
||||
3. **Single Palette Application** - Applied once in `RenderRoomGraphics()`
|
||||
4. **EditorCard UI** - No rigid tabs, flexible docking
|
||||
5. **Backend/UI Separation** - DungeonEditorSystem (backend) + DungeonEditorV2 (UI)
|
||||
|
||||

|
||||
|
||||
## Critical Bugs Fixed
|
||||
|
||||
### Bug #1: Segfault on Startup ✅
|
||||
**Cause**: `ImGui::GetID()` called before ImGui context ready
|
||||
**Fix**: Moved to `Update()` when ImGui is initialized
|
||||
**File**: `dungeon_editor_v2.cc:160-163`
|
||||
|
||||
### Bug #2: Floor Values Always Zero ✅
|
||||
**Cause**: `RenderRoomGraphics()` called before `LoadObjects()`
|
||||
**Fix**: Correct sequence - LoadRoomGraphics → LoadObjects → RenderRoomGraphics
|
||||
**File**: `dungeon_editor_v2.cc:442-460`
|
||||
**Impact**: Floor graphics now load correctly (4, 8, etc. instead of 0)
|
||||
|
||||
### Bug #3: Duplicate Floor Variables ✅
|
||||
**Cause**: `floor1` (public) vs `floor1_graphics_` (private)
|
||||
**Fix**: Removed public members, added accessors: `floor1()`, `set_floor1()`
|
||||
**File**: `room.h:341-350`
|
||||
**Impact**: UI floor edits now trigger immediate re-render
|
||||
|
||||
### Bug #4: ObjectRenderer Confusion ✅
|
||||
**Cause**: Two rendering systems (ObjectDrawer vs ObjectRenderer)
|
||||
**Fix**: Removed ObjectRenderer, standardized on ObjectDrawer
|
||||
**Files**: `dungeon_canvas_viewer.h/cc`, `dungeon_object_selector.h/cc`
|
||||
**Impact**: Single, clear rendering path
|
||||
|
||||
### Bug #5: Duplicate Property Detection ✅
|
||||
**Cause**: Two property change blocks, second never ran
|
||||
**Fix**: Removed duplicate block
|
||||
**File**: `dungeon_canvas_viewer.cc:95-118 removed`
|
||||
**Impact**: Property changes now trigger correct re-renders

## Architecture
|
||||
|
||||
### Component Overview
|
||||
|
||||
```
|
||||
DungeonEditorV2 (UI Layer)
|
||||
├─ Card-based UI system
|
||||
├─ Room window management
|
||||
├─ Component coordination
|
||||
└─ Lazy loading
|
||||
|
||||
DungeonEditorSystem (Backend Layer)
|
||||
├─ Sprite management
|
||||
├─ Item management
|
||||
├─ Entrance/Door/Chest management
|
||||
├─ Undo/Redo functionality
|
||||
└─ Dungeon-wide operations
|
||||
|
||||
Room (Data Layer)
|
||||
├─ Self-contained buffers (bg1_buffer_, bg2_buffer_)
|
||||
├─ Object storage (tile_objects_)
|
||||
├─ Graphics loading
|
||||
└─ Rendering pipeline
|
||||
```
|
||||
|
||||
### Room Rendering Pipeline
|
||||
|
||||
```
|
||||
1. LoadRoomGraphics(blockset)
|
||||
└─> Reads blocks[] from ROM
|
||||
└─> Loads blockset data → current_gfx16_
|
||||
|
||||
2. LoadObjects()
|
||||
└─> Parses object data from ROM
|
||||
└─> Creates tile_objects_[]
|
||||
└─> SETS floor1_graphics_, floor2_graphics_ ← CRITICAL!
|
||||
|
||||
3. RenderRoomGraphics() [SELF-CONTAINED]
|
||||
├─> DrawFloor(floor1_graphics_, floor2_graphics_)
|
||||
├─> DrawBackground(current_gfx16_)
|
||||
├─> RenderObjectsToBackground()
|
||||
│ └─> ObjectDrawer::DrawObjectList()
|
||||
├─> SetPalette(full_90_color_dungeon_palette)
|
||||
└─> QueueTextureCommand(CREATE, bg1_bmp, bg2_bmp)
|
||||
|
||||
4. DrawRoomBackgroundLayers(room_id)
|
||||
└─> ProcessTextureQueue() → GPU textures
|
||||
└─> canvas_.DrawBitmap(bg1, bg2)
|
||||
|
||||
5. DrawObjectPositionOutlines(room)
|
||||
└─> Colored rectangles by layer (Red/Green/Blue)
|
||||
└─> Object ID labels
|
||||
```
|
||||
|
||||
### Key Insight: Object Rendering
|
||||
|
||||
Objects are drawn as **indexed pixel data** into buffers, then `SetPalette()` colorizes BOTH background tiles AND objects simultaneously. This is why palette application must happen AFTER object drawing.
|
||||
|
||||
---
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Build
|
||||
```bash
|
||||
cd /Users/scawful/Code/yaze
|
||||
cmake --preset mac-ai -B build_ai
|
||||
cmake --build build_ai --target yaze -j12
|
||||
```
|
||||
|
||||
### Run
|
||||
```bash
|
||||
# Open dungeon editor
|
||||
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon
|
||||
|
||||
# Open specific room
|
||||
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon --cards="Room 0x00"
|
||||
```
|
||||
|
||||
### Expected Visuals
|
||||
- ✅ **Floor tiles**: Proper dungeon graphics with correct colors
|
||||
- ✅ **Floor values**: Show 4, 8, etc. (not 0!)
|
||||
- ✅ **Object outlines**: Colored rectangles indicating object positions
|
||||
- 🟥 Red = Layer 0 (main floor/walls)
|
||||
- 🟩 Green = Layer 1 (upper decorations/chests)
|
||||
- 🟦 Blue = Layer 2 (stairs/transitions)
|
||||
- ✅ **Object IDs**: Labels showing "0x10", "0x20", etc.
|
||||
|
||||
---
|
||||
|
||||
## Object Visualization
|
||||
|
||||
### DrawObjectPositionOutlines()
|
||||
|
||||
Shows where objects are placed with colored rectangles:
|
||||
|
||||
```cpp
|
||||
// Color coding by layer
|
||||
Layer 0 → Red (most common - walls, floors)
|
||||
Layer 1 → Green (decorations, chests)
|
||||
Layer 2 → Blue (stairs, exits)
|
||||
|
||||
// Size calculation
|
||||
width = (obj.size() & 0x0F + 1) * 8 pixels
|
||||
height = ((obj.size() >> 4) & 0x0F + 1) * 8 pixels
|
||||
|
||||
// Labels
|
||||
Each rectangle shows object ID (0x10, 0x20, etc.)
|
||||
```
|
||||
|
||||
This helps verify object positions even if graphics don't render yet.
|
||||
|
||||

|
||||
|
||||
## Testing
|
||||
|
||||
### Debug Commands
|
||||
```bash
|
||||
# Check floor values (should NOT be 0)
|
||||
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon 2>&1 | grep "floor1="
|
||||
|
||||
# Check object loading
|
||||
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon 2>&1 | grep "Drawing.*objects"
|
||||
|
||||
# Check object drawing details
|
||||
./build_ai/bin/yaze.app/Contents/MacOS/yaze --rom_file=zelda3.sfc --editor=Dungeon 2>&1 | grep "Writing Tile16"
|
||||
```
|
||||
|
||||
### Expected Debug Output
|
||||
```
|
||||
[DungeonEditorV2] Loaded room 0 graphics from ROM
|
||||
[DungeonEditorV2] Loaded room 0 objects from ROM
|
||||
[RenderRoomGraphics] Room 0: floor1=4, floor2=8, blocks_size=16 ← NOT 0!
|
||||
[DungeonEditorV2] Rendered room 0 to bitmaps
|
||||
[ObjectDrawer] Drawing 15 objects
|
||||
[ObjectDrawer] Drew 15 objects, skipped 0
|
||||
```
|
||||
|
||||
### Visual Checklist
|
||||
- [ ] Floor tiles render with correct dungeon graphics
|
||||
- [ ] Floor values show non-zero numbers
|
||||
- [ ] Object position outlines visible (colored rectangles)
|
||||
- [ ] Can edit floor1/floor2 values
|
||||
- [ ] Changes update canvas immediately
|
||||
- [ ] Multiple rooms can be opened and docked
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Floor tiles still blank/wrong?
|
||||
**Check**: Debug output should show `floor1=4, floor2=8` (NOT 0)
|
||||
**If 0**: Loading order issue - verify LoadObjects() runs before RenderRoomGraphics()
|
||||
**File**: `dungeon_editor_v2.cc:442-460`
|
||||
|
||||
### Objects not visible?
|
||||
**Check**: Object position outlines should show colored rectangles
|
||||
**If no outlines**: Object loading failed - check LoadObjects()
|
||||
**If outlines but no graphics**: ObjectDrawer or tile loading issue
|
||||
**Debug**: Check ObjectDrawer logs for "has X tiles"
|
||||
|
||||
### Floor editing doesn't work?
|
||||
**Check**: Using floor accessors: `floor1()`, `set_floor1()`
|
||||
**Not**: Direct members `room.floor1` (removed)
|
||||
**File**: `dungeon_canvas_viewer.cc:90-106`
|
||||
|
||||
### Performance degradation with multiple rooms?
|
||||
**Cause**: Each room = ~2MB (2x 512x512 bitmaps)
|
||||
**Solution**: Implement texture pooling (future work)
|
||||
**Workaround**: Close unused room windows
|
||||
|
||||
---
|
||||
|
||||
## Future Work
|
||||
|
||||
### High Priority
|
||||
1. **Verify wall graphics render** - ObjectDrawer pipeline may need debugging
|
||||
2. **Implement room layout rendering** - Show structural walls/floors/pits
|
||||
3. **Remove LoadGraphicsSheetsIntoArena()** - Placeholder code no longer needed
|
||||
4. **Update room graphics card** - Show per-room graphics instead of Arena sheets
|
||||
|
||||
### Medium Priority
|
||||
5. **Texture atlas infrastructure** - Lay groundwork for future optimization
|
||||
6. **Move backend logic to DungeonEditorSystem** - Cleaner UI/backend separation
|
||||
7. **Performance optimization** - Texture pooling or lazy loading
|
||||
|
||||
### Low Priority
|
||||
8. **Extract ROM addresses** - Move constants to dungeon_rom_addresses.h
|
||||
9. **Remove unused variables** - palette_, background_tileset_, sprite_tileset_
|
||||
10. **Consolidate duplicates** - blockset/spriteset cleanup

||||

|
||||
## Code Reference
|
||||
|
||||
### Loading Order (CRITICAL)
|
||||
```cpp
|
||||
// dungeon_editor_v2.cc:442-460
|
||||
if (room.blocks().empty()) {
|
||||
room.LoadRoomGraphics(room.blockset); // 1. Load blocks
|
||||
}
|
||||
if (room.GetTileObjects().empty()) {
|
||||
room.LoadObjects(); // 2. Load objects (sets floor graphics!)
|
||||
}
|
||||
if (needs_render || !bg1_bitmap.is_active()) {
|
||||
room.RenderRoomGraphics(); // 3. Render with correct data
|
||||
}
|
||||
```
|
||||
|
||||
### Floor Accessors
|
||||
```cpp
|
||||
// room.h:341-350
|
||||
uint8_t floor1() const { return floor1_graphics_; }
|
||||
uint8_t floor2() const { return floor2_graphics_; }
|
||||
void set_floor1(uint8_t value) {
|
||||
floor1_graphics_ = value;
|
||||
// Triggers re-render in UI code
|
||||
}
|
||||
void set_floor2(uint8_t value) {
|
||||
floor2_graphics_ = value;
|
||||
}
|
||||
```
|
||||
|
||||
### Object Visualization
|
||||
```cpp
|
||||
// dungeon_canvas_viewer.cc:410-459
|
||||
void DungeonCanvasViewer::DrawObjectPositionOutlines(const zelda3::Room& room) {
|
||||
for (const auto& obj : room.GetTileObjects()) {
|
||||
// Convert to canvas coordinates
|
||||
auto [canvas_x, canvas_y] = RoomToCanvasCoordinates(obj.x(), obj.y());
|
||||
|
||||
// Calculate dimensions from size field
|
||||
int width = (obj.size() & 0x0F + 1) * 8;
|
||||
int height = ((obj.size() >> 4) & 0x0F + 1) * 8;
|
||||
|
||||
// Color by layer
|
||||
ImVec4 color = (layer == 0) ? Red : (layer == 1) ? Green : Blue;
|
||||
|
||||
// Draw outline and ID label
|
||||
canvas_.DrawRect(canvas_x, canvas_y, width, height, color);
|
||||
canvas_.DrawText(absl::StrFormat("0x%02X", obj.id_), canvas_x + 2, canvas_y + 2);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## User Decisions
|
||||
|
||||
Based on OPEN_QUESTIONS.md answers:
|
||||
|
||||
1. **DungeonEditorSystem** = Backend logic (keep, move more logic to it)
|
||||
2. **ObjectRenderer** = Remove (obsolete, use ObjectDrawer)
|
||||
3. **LoadGraphicsSheetsIntoArena()** = Remove (per-room graphics instead)
|
||||
4. **Test segfault** = Pre-existing (ignore for now)
|
||||
5. **Performance** = Texture atlas infrastructure (future-proof)
|
||||
6. **Priority** = Make walls/layouts visible with rect outlines
|
||||
|
||||
---
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate
|
||||
1. ⬜ Remove `LoadGraphicsSheetsIntoArena()` method
|
||||
2. ⬜ Implement room layout rendering
|
||||
3. ⬜ Create texture atlas stub
|
||||
4. ⬜ Verify wall object graphics render
|
||||
|
||||
### Short-term
|
||||
5. ⬜ Search for remaining ObjectRenderer references
|
||||
6. ⬜ Update room graphics card for per-room display
|
||||
7. ⬜ Move sprite/item/entrance logic to DungeonEditorSystem
|
||||
|
||||
### Future
|
||||
8. ⬜ Implement texture atlas fully
|
||||
9. ⬜ Extract ROM addresses/enums to separate files
|
||||
10. ⬜ Remove unused variables (palette_, background_tileset_, sprite_tileset_)
