# Sprint 8-10: 1. Obergeschoss — 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 first-floor rooms (XRay, Pharmacy, Lab, Patient Room) with the X-ray machine's plate slide-in animation as the highlight feature.

**Architecture:** Floor 1 follows the same side-by-side room layout as Floor 0 — four rooms at X offsets 0, 1280, 2560, 3840 within the `Floor1` node. `XRayMachine` is a new custom component (like `Ambulance`) with its own state machine. The existing `NavigationArrow` and `ElevatorButton` components are reused unchanged. `Main.tscn` is updated to replace the Floor 1 placeholder nodes with the real room scenes.

**Tech Stack:** Godot 4.6.2, GDScript (static typing), existing `InteractiveObject` base class, placeholder ColorRect graphics.

## File Map

| Action | File | Responsibility |
|--------|------|----------------|
| Create | `scripts/objects/xray_machine.gd` | Plate slide-in animation, 4-state machine (IDLE → SLIDING_IN → EXPOSING → SLIDING_OUT) |
| Create | `scenes/objects/XRayMachine.tscn` | Machine body + viewer screen + sliding plate (all ColorRect) |
| Create | `scenes/rooms/floor1/XRay.tscn` | Exam table, XRayMachine instance, PlasterStation |
| Create | `scenes/rooms/floor1/Pharmacy.tscn` | Medicine shelf, counter, 4 positive medicine objects |
| Create | `scenes/rooms/floor1/Lab.tscn` | Lab bench, 4 interactive lab objects |
| Create | `scenes/rooms/floor1/PatientRoom.tscn` | 2 beds, TV, bedside table |
| Modify | `scenes/main/Main.tscn` | Replace Floor1 placeholder with 4 rooms + nav arrows; move elevator buttons |

**Room layout in Floor1 (local X positions):**
- XRay: x=0 (room index 0) — camera center world (640, -360)
- Pharmacy: x=1280 (room index 1) — camera center world (1920, -360)
- Lab: x=2560 (room index 2) — camera center world (3200, -360)
- PatientRoom: x=3840 (room index 3) — camera center world (4480, -360)

**XRayMachine visual layout (local space, origin = machine base center):**
- MachineBody: grey ColorRect 80×200 at local (-40, -200) — tall vertical machine
- MachineArm: grey ColorRect 220×24 at local (-40, -180) — horizontal arm over table
- ViewerFrame: dark ColorRect 80×60 at local (-40, -195) — screen housing on machine
- Viewer: very dark ColorRect 66×46 at local (-33, -189) — screen, lights up during scan
- Plate: Node2D child, starts at local (-50, 20); contains PlateBody (200×14 ColorRect)
  - PLATE_PARKED_X = -50.0 (behind/inside machine, hidden)
  - PLATE_ACTIVE_X = 130.0 (extends to the right, under the exam table)

**Floor1 elevator buttons (moved to avoid overlap with nav arrows at x=1200):**
- ElevatorDown1: position (1100, 540) → target_floor = 0
- ElevatorUp1: position (1100, 180) → target_floor = 2

## Task 6: Update Main.tscn — wire up Floor 1

**Files:**
- Modify: `scenes/main/Main.tscn`

**Changes from current file:**
1. `load_steps` increases from 13 → 17 (add 4 new ext_resources: XRay, Pharmacy, Lab, PatientRoom)
2. Add 4 new ext_resource declarations (ids 12–15)
3. In the Floor1 section: **remove** the placeholder `Background`, `FloorLabel`, `FloorRect` nodes
4. **Add** 4 room instances to Floor1 at x offsets 0, 1280, 2560, 3840
5. **Move** ElevatorDown1 from (1200, 540) → (1100, 540) and ElevatorUp1 from (1200, 180) → (1100, 180)
6. **Add** 6 NavigationArrow instances for Floor1 room navigation

**NavigationArrow positions in Floor1 local space:**

| Node | X | Y | target_floor | target_room | label |
|------|---|---|---|---|---|
| NavRight0to1_F1 | 1200 | 480 | 1 | 1 | → |
| NavLeft1to0_F1 | 1340 | 480 | 1 | 0 | ← |
| NavRight1to2_F1 | 2480 | 480 | 1 | 2 | → |
| NavLeft2to1_F1 | 2600 | 480 | 1 | 1 | ← |
| NavRight2to3_F1 | 3760 | 480 | 1 | 3 | → |
| NavLeft3to2_F1 | 3920 | 480 | 1 | 2 | ← |

- [ ] **Step 1: Read current Main.tscn**

Read `F:/Development/_gameDev/Cozypaw-Hospital/scenes/main/Main.tscn` to confirm the current content before replacing.

- [ ] **Step 2: Write the complete new Main.tscn**

## Self-Review: Spec Coverage Check

| Sprint 8-10 requirement | Covered by |
|-------------------------|-----------|
| Röntgen mit Slide-Animation | Task 1+2: XRayMachine with 4-state plate animation |
| Apotheke (alle Medikamente positiv) | Task 3: Pharmacy with VitaminBottle, BandageRoll, SyrupBottle, MedicineBox |
| Labor | Task 4: Lab with Microscope, TestTubeRack, ReagentBottle, PetriDish |
| Patientenzimmer | Task 5: PatientRoom with 2 beds, TV, BedsideTable |
| All rooms accessible via elevator + horizontal nav | Task 6: Full Main.tscn wiring |

**Placeholder scan:** All code blocks complete. No "TBD" or "TODO". ViewerFrame/Viewer nodes referenced in script by node name — both exist in XRayMachine.tscn. ✓

**Type consistency:**
- `XRayMachine._on_plate_in()` used as signal callback: matches `tween.finished.connect(_on_plate_in)` ✓
- `VIEWER_LIT_COLOR` / `VIEWER_DARK_COLOR` used in `_on_plate_in()` and `_start_slide_out()` ✓
- `Plate` node accessed as `Node2D` (not `ColorRect`) — correct, Plate is a Node2D in the scene ✓
- `Viewer` node accessed as `ColorRect` — correct, Viewer is a ColorRect in the scene ✓

## Smoke Test Checklist (manual, on device after completion)

- [ ] Elevator from Floor 0 lands at Floor 1 XRay room
- [ ] "→" navigates Floor 1: XRay → Pharmacy → Lab → PatientRoom and back
- [ ] Tapping XRayMachine: plate slides out to the right, viewer lights up blue-white, plate slides back, viewer goes dark
- [ ] Tapping XRayMachine again during animation: nothing happens (state guard)
- [ ] All medicine objects in Pharmacy bounce when tapped (all positive, no harmful items)
- [ ] All lab objects in Lab bounce when tapped
- [ ] TV and BedsideTable in PatientRoom bounce when tapped
- [ ] Elevator Up from Floor 1 navigates to Floor 2 placeholder
- [ ] Elevator Down from Floor 1 lands at Floor 0 Reception (room 0)
- [ ] Bunny character can be dragged to Floor 1 and position is saved
