# Sprint 5-7: Erdgeschoss — Implementation Plan
> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
**Goal:** Four fully interactive ground-floor rooms (Reception, Gift Shop, Restaurant, Emergency Room) with horizontal room-to-room navigation and an ambulance drive-in animation.
**Architecture:** Floor 0 rooms are laid out side-by-side at 1280 px intervals along the X axis. `RoomNavigator` is extended to tween the camera both horizontally (room index) and vertically (floor index). `NavigationArrow` objects placed at room boundaries handle left/right navigation. When `go_to_floor()` is called, the room resets to index 0. The ambulance in Emergency Room drives in automatically the first time the player navigates there.
**Tech Stack:** Godot 4.6.2, GDScript (static typing), placeholder ColorRect graphics, existing `InteractiveObject` + `DragDropComponent` base classes.

## File Map
| Action | File | Responsibility |
|--------|------|----------------|
| Modify | `scripts/systems/room_navigator.gd` | Add horizontal room navigation: `go_to_room(floor, room)` |
| Create | `scripts/objects/navigation_arrow.gd` | Tappable arrow navigating to `(target_floor, target_room)` |
| Create | `scenes/objects/NavigationArrow.tscn` | Visual placeholder (blue button + label) |
| Modify | `scenes/rooms/floor0/Reception.tscn` | Add bench ×2, bell, potted plant |
| Create | `scenes/rooms/floor0/GiftShop.tscn` | Shelf, counter, 4 interactive objects |
| Create | `scenes/rooms/floor0/Restaurant.tscn` | 3 tables, kitchen counter, 4 interactive objects |
| Create | `scripts/objects/ambulance.gd` | Drive-in/out animation, triggered by `RoomNavigator.room_changed` |
| Create | `scenes/objects/Ambulance.tscn` | ColorRect-based ambulance visual |
| Create | `scenes/rooms/floor0/EmergencyRoom.tscn` | Ambulance bay, medical table, IV stand, 2 interactive objects |
| Modify | `scenes/main/Main.tscn` | Add 4 rooms to Floor0, navigation arrows, elevator reposition |
**Room layout in Floor0 (local X positions):**
- Reception: x=0 (room index 0), camera center world (640, 360)
- GiftShop: x=1280 (room index 1), camera center world (1920, 360)
- Restaurant: x=2560 (room index 2), camera center world (3200, 360)
- EmergencyRoom: x=3840 (room index 3), camera center world (4480, 360)

## Task 8: Wire up Floor 0 in Main.tscn
**Files:**
- Modify: `scenes/main/Main.tscn`
**Changes:**
- Add GiftShop, Restaurant, EmergencyRoom as instances at x offsets 1280, 2560, 3840 in Floor0
- Move ElevatorUp0 to position (1100, 160) to avoid overlap with navigation arrows
- Add 6 NavigationArrow instances at room boundaries (3 pairs)
- `load_steps` changes from 9 → 13 (add 4 new ExtResources)
**NavigationArrow positions in Floor0 local space:**
| Node name | X | Y | target_floor | target_room | label |
|-----------|---|---|---|---|---|
| NavRight0to1 | 1200 | 480 | 0 | 1 | → |
| NavLeft1to0 | 1340 | 480 | 0 | 0 | ← |
| NavRight1to2 | 2480 | 480 | 0 | 2 | → |
| NavLeft2to1 | 2600 | 480 | 0 | 1 | ← |
| NavRight2to3 | 3760 | 480 | 0 | 3 | → |
| NavLeft3to2 | 3920 | 480 | 0 | 2 | ← |
**Visibility verification (camera center ± 640 horizontal):**
- Room 0 (cam x=640): screen x 01280 → NavRight0to1 at 1200 ✓, elevator at 1100 ✓
- Room 1 (cam x=1920): screen x 12802560 → NavLeft1to0 at 1340 ✓, NavRight1to2 at 2480 ✓
- Room 2 (cam x=3200): screen x 25603840 → NavLeft2to1 at 2600 ✓, NavRight2to3 at 3760 ✓
- Room 3 (cam x=4480): screen x 38405120 → NavLeft3to2 at 3920 ✓
- [ ] **Step 1: Replace Main.tscn**

## Self-Review: Spec Coverage Check
| Sprint 5-7 requirement | Covered by |
|------------------------|-----------|
| Empfang komplett | Task 3: bench ×2, bell, potted plant, number display |
| Geschenke-Shop | Task 4: full scene with shelf, 4 interactive objects |
| Restaurant | Task 5: full scene with 3 tables, 4 interactive objects |
| Notaufnahme | Task 7: full scene with ambulance bay, table, IV stand |
| Krankenwagen-Animation | Task 6: drive-in on room_changed, drive-out on tap |
| Horizontal room navigation | Task 1 + 2: RoomNavigator + NavigationArrow |
| All rooms accessible from game | Task 8: all wired up in Main.tscn |
**Placeholder scan:** All code blocks are complete. No "TBD" or "implement later" present. UIDs are convention-based and may be regenerated by Godot on first open — this is expected behavior.
**Type consistency:** `room_changed(floor_index: int, room_index: int)` signal defined in Task 1 and consumed in Task 6 (`_on_room_changed`). ✓ `go_to_room(floor_index: int, room_index: int)` defined in Task 1 and called in Task 2 (`NavigationArrow._on_pressed()`). ✓

## Smoke Test Checklist (manual, on device after completion)
- [ ] Game starts at Reception (camera center visible, green background)
- [ ] "→" arrow in Reception navigates smoothly to Gift Shop
- [ ] "←" arrow in Gift Shop navigates back to Reception
- [ ] Full chain: Reception → Gift Shop → Restaurant → Emergency works both directions
- [ ] Elevator Up from Reception navigates to Floor 1
- [ ] Elevator Down from Floor 1 lands at Reception (room 0), not Emergency Room
- [ ] Tapping flower/bell in Reception plays bounce animation
- [ ] Navigating to Emergency Room for the first time: ambulance drives in from right
- [ ] Tapping ambulance after it's parked: drives back out
- [ ] Tapping ambulance again: drives back in
- [ ] Dragging Bunny character across rooms works correctly
- [ ] Save/load preserves Bunny position after app restart
