Objects are placed ON TOP and can be moved/edited. This allows for large rooms, 4-quadrant rooms, tall/wide rooms, etc. + +--- + +## Next Development Steps + +### High Priority (Must Do) + +#### 1. Implement Room Layout Base Layer Rendering +**File**: `dungeon_canvas_viewer.cc:377-391` (stub exists) + +**What**: Render the immovable room structure (walls, floors, pits) + +**Implementation**: +```cpp +void DungeonCanvasViewer::DrawRoomLayout(const zelda3::Room& room) { + const auto& layout = room.GetLayout(); + + // TODO: Load layout if not loaded + // layout.LoadLayout(room_id); + + // Get structural elements + auto walls = layout.GetObjectsByType(RoomLayoutObject::Type::kWall); + auto floors = layout.GetObjectsByType(RoomLayoutObject::Type::kFloor); + auto pits = layout.GetObjectsByType(RoomLayoutObject::Type::kPit); + + // Draw walls (dark gray, semi-transparent) + for (const auto& wall : walls) { + auto [x, y] = RoomToCanvasCoordinates(wall.x(), wall.y()); + canvas_.DrawRect(x, y, 8, 8, ImVec4(0.3f, 0.3f, 0.3f, 0.6f)); + } + + // Draw pits (orange warning) + for (const auto& pit : pits) { + auto [x, y] = RoomToCanvasCoordinates(pit.x(), pit.y()); + canvas_.DrawRect(x, y, 8, 8, ImVec4(1.0f, 0.5f, 0.0f, 0.7f)); + } +} +``` + +**Reference**: `src/app/zelda3/dungeon/room_layout.h/cc` for LoadLayout() logic + +--- + +#### 2. Door Rendering at Room Edges +**What**: Render doors with proper patterns at room connections + +**Pattern Reference**: ZScream's door drawing patterns + +**Implementation**: +```cpp +void DungeonCanvasViewer::DrawDoors(const zelda3::Room& room) { + // Doors stored in room data + // Position at room edges (North/South/East/West) + // Use current_gfx16_ graphics data + + // TODO: Get door data from room.GetDoors() or similar + // TODO: Use ObjectDrawer patterns for door graphics + // TODO: Draw at interpolation points between rooms +} +``` + +--- + +#### 3. Object Name Labels from String Array +**File**: `dungeon_canvas_viewer.cc:416` (DrawObjectPositionOutlines) + +**What**: Show real object names instead of just IDs + +**Implementation**: +```cpp +// Instead of: +std::string label = absl::StrFormat("0x%02X", obj.id_); + +// Use: +std::string object_name = GetObjectName(obj.id_); +std::string label = absl::StrFormat("%s\n0x%02X", object_name.c_str(), obj.id_); + +// Helper function: +std::string GetObjectName(int16_t object_id) { + // TODO: Reference ZScream's object name arrays + // TODO: Map object ID → name string + // Example: 0x10 → "Wall (North)" + return "Object"; +} +``` + +--- + +#### 4.

Update current_room_id on Card Hover +**What**: Update DungeonEditorV2::current_room_id_ when hovering room cards + +**Implementation**: +```cpp +// In dungeon_editor_v2.cc, after room_card->Begin(): +if (ImGui::IsWindowHovered()) { + current_room_id_ = room_id; +} +``` + +--- + +#### 6. Fix InputHexByte +/- Button Events +**File**: `src/app/gui/input.cc` (likely) + +**Issue**: Buttons don't respond to clicks + +**Investigation Needed**: +- Check if button click events are being captured +- Verify event logic matches working examples +- Keep existing event style if it works elsewhere + +--- + +#### 7. Update Room Graphics Card +**File**: `dungeon_editor_v2.cc:856-920` + +**What**: Show per-room graphics from `current_gfx16_` instead of Arena sheets + +**Implementation**: +```cpp +// Instead of Arena sheets: +auto& gfx_sheet = gfx::Arena::Get().gfx_sheets()[block]; + +// Use room's current_gfx16_: +const auto& gfx_buffer = room.get_gfx_buffer(); // Returns current_gfx16_ +// Extract 128x128 block from gfx_buffer +// Display as 128x32 strips (16 blocks, 2 columns) +``` + +--- + +### Lower Priority (Nice to Have) + +#### 8. Selection System with Primitive Squares +**What**: Allow selecting objects even if graphics don't render + +**Current**: Selection works on bitmaps +**Enhancement**: Selection works on position outlines + +--- + +#### 9. Move Backend Logic to DungeonEditorSystem +**What**: Separate UI (V2) from data operations (System) + +**Migration**: +- Sprite management → DungeonEditorSystem +- Item management → DungeonEditorSystem +- Entrance/Door/Chest → DungeonEditorSystem +- Undo/Redo → DungeonEditorSystem + +**Result**: DungeonEditorV2 becomes pure UI coordinator + +--- + +#### 10.
