+> Smoke Tests werden nach jedem Sprint manuell auf einem echten Android-Tablet durchgeführt.
+> Ziel ist kein vollständiger Test, sondern ein schnelles "Geht es grundlegend?" vor dem Zeigen an die Kinder.
+> Neue Sprint-Abschnitte werden jeweils zu Beginn des Sprints ergänzt.
+
+---
+
+## Basis-Tests (jeder Sprint)
+
+Diese Tests werden bei jedem Sprint-Abschluss durchgeführt, unabhängig vom Inhalt.
+
+- [ ] App startet ohne Absturz
+- [ ] Kein Freeze oder schwarzer Screen in den ersten 5 Sekunden
+- [ ] Musik spielt beim Start (ca. 60% Lautstärke)
+- [ ] HUD: Back-Button sichtbar und funktionsfähig
+- [ ] HUD: Musik-Toggle funktioniert (an/aus)
+- [ ] Performance: Keine sichtbaren Ruckler beim Scrollen/Navigieren
+- [ ] Touch-Targets: Alle interaktiven Elemente mit Kinderfingern erreichbar (min. 48dp)
+- [ ] Offline: Spiel funktioniert vollständig ohne WLAN/Mobilfunk
+- [ ] Kein Netzwerk-Request im Hintergrund (DevTools / Android Profiler prüfen)

+
+Ziel: Erster spielbarer Raum (Empfang/Reception), Drag & Drop einer Figur, ein interaktives Objekt.

+- [ ] Figur (Häschen oder Kätzchen) ist auf dem Bildschirm sichtbar
+- [ ] Figur lässt sich per Touch aufheben (Drag-Start)

+# Sprint 11-13: 2. 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:** Three fully interactive second-floor rooms (Ultrasound with continuous heartbeat animation, Delivery Room with mama-arrives animation, Nursery with rocking cradles) wired into Main.tscn.
+
+**Architecture:** Floor 2 follows the same side-by-side layout — three rooms at X offsets 0, 1280, 2560 within the `Floor2` node (Floor 2 has only 3 rooms, unlike Floors 0 and 1 which have 4). Two new animated components are introduced: `UltrasoundMachine` (continuous looping heartbeat tween) and `DeliveryBed` (4-state FSM: mama slides in, baby fades in, tap again to reset). `Cradle` adds a rocking rotation animation on tap. `Main.tscn` is updated to replace the Floor 2 placeholder nodes with the real rooms.
+
+**Tech Stack:** Godot 4.6.2, GDScript (static typing), existing `InteractiveObject` base class, placeholder ColorRect graphics.
+
+---
+
+## File Map

+| Create | `scripts/objects/delivery_bed.gd` | 4-state FSM: IDLE → MAMA_ARRIVING → COMPLETE → RESETTING |
+| Create | `scenes/objects/DeliveryBed.tscn` | Bed frame + Mama Node2D (slides in) + Baby Node2D (fades in) |
+| Create | `scripts/objects/cradle.gd` | Rocking rotation animation on tap (2-state FSM) |
+| Create | `scenes/objects/Cradle.tscn` | Hanging cradle with suspension ropes and basket |

+
+**Files:**

+2. Add 3 new ext_resource declarations (ids 16–18)
+3. In the Floor2 section: **remove** the placeholder `Background`, `FloorLabel`, `FloorRect` nodes
+4. **Add** 3 room instances to Floor2 at x offsets 0, 1280, 2560 *(no room 3)*
+5. **Move** ElevatorDown2 from (1200, 360) → (1100, 540) *(consistent with Floor1 pattern)*
+6. **Add** 4 NavigationArrow instances for Floor2 room navigation *(only 2 boundaries, not 3)*
+
+**load_steps arithmetic:** 15 existing ext_resources + 3 new = 18 ext_resources + 1 sub_resource + 1 scene root = 20.
+
+- [ ] **Step 1: Read current Main.tscn**

+## Self-Review: Spec Coverage Check
+
+| Sprint 11-13 requirement | Covered by |
+|--------------------------|-----------|
+| Ultraschall (sanfte Herzschlag-Animation) | Task 1: UltrasoundMachine with looping scale tween on HeartbeatDot; Task 4: Ultrasound room |
+| Kreißsaal (Mama kommt rein, Baby ist da) | Task 2: DeliveryBed 4-state FSM (tap → mama slides in → baby fades in → tap → reset); Task 5: DeliveryRoom |
+| Säuglingsstation mit Wiegen | Task 3: Cradle with pendulum rotation; Task 6: Nursery with 3 Cradle instances on a rail |
+| All rooms accessible via elevator + horizontal nav | Task 7: Main.tscn with 4 nav arrows for 2 boundaries + ElevatorDown2 |
+| Keine Gift-Mechaniken (product principle) | All interactive objects: GelBottle, Blanket, FlowerVase, BabyBlanket, TeddyBear, MilkBottle — all safe/positive |
+
+**Placeholder scan:** All code blocks complete. No TBD or TODO. Node paths referenced in scripts match scenes:
+- `ultrasound_machine.gd` → `"HeartbeatDot"` — exists as direct child of UltrasoundMachine ✓
+- `delivery_bed.gd` → `"Mama"` (Node2D), `"Baby"` (Node2D) — both exist as direct children of DeliveryBed ✓
+- `cradle.gd` → rotates `self` — no node path lookup needed ✓
+
+**Type consistency:**
+- `_on_mama_arrived()` used as `tween.finished.connect(_on_mama_arrived)` — method callable, matches function signature ✓
+- `Baby.modulate:a` tweened as float — `modulate` is Color, `:a` accesses the alpha channel as float ✓
+- `MAMA_OFFSCREEN_X = -600.0` used in `_ready()` and `_start_reset()` — consistent ✓
+- `MAMA_PARKED_X = -100.0` used only in `_start_arrival()` ✓
+- `rotation_degrees` tweened as float (ROCK_ANGLE = 15.0) — matches `self.rotation_degrees` property type ✓
+
+**Floor2 room count:** 3 rooms (not 4). Nav arrows: 4 total (2 boundaries × 2 directions). ElevatorDown2 only (no ElevatorUp2 — Floor 2 is the top floor). ✓
+
+---
+
+## Smoke Test Checklist (manual, on device after completion)
+
+- [ ] Elevator from Floor 1 lands at Floor 2 Ultrasound room
+- [ ] Heartbeat animation starts automatically on entering Ultrasound room (green dot pulses every ~0.84s)
+- [ ] "→" navigates Floor 2: Ultrasound → DeliveryRoom → Nursery and back with "←"
+- [ ] No "→" arrow visible in Nursery room (no room 3)
+- [ ] Tapping DeliveryBed: Mama slides in from left, Baby appears
+- [ ] Tapping DeliveryBed again: Mama slides out left, Baby disappears
+- [ ] Tapping DeliveryBed during animation: nothing happens (state guard)
+- [ ] Tapping any Cradle: cradle rocks (swings ±15°, returns to center)
+- [ ] Tapping Cradle during rocking: nothing (state guard)
+- [ ] All interactive objects (GelBottle, Blanket, FlowerVase, BabyBlanket, TeddyBear, MilkBottle) bounce on tap
+- [ ] Elevator Down from Floor 2 → Floor 1 XRay room
+- [ ] Bunny can be dragged to Floor 2

Steven Wroblewski	6bc199f6c1	fix(core): correct camera Y offset in RoomNavigator floor navigation Floor N spans from N-720 to (N-1)-720. The camera must center at the floor midpoint, so target_y = floor_index * -720 + 360 (half floor height). Previous formula placed the camera at the floor boundary, showing content split between two floors. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-17 13:26:03 +02:00
Steven Wroblewski	f4611e2443	fix(core): serialize character positions as [x,y] arrays for JSON compatibility Vector2 is not a JSON-native type — JSON.stringify converts it to a string, which cannot be assigned back to a Vector2 return type on load. Positions are now saved as [x, y] float arrays and reconstructed as Vector2 in apply_save_data. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-17 13:22:56 +02:00
Steven Wroblewski	22f4b23897	fix(objects): replace Area2D.input_event with _input() for reliable Android touch Area2D.input_event is unreliable on Android with gl_compatibility renderer. Switched to manual _input() hit detection using canvas_transform coordinate conversion, consistent with the DragDropComponent approach already used in this project. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-17 13:20:14 +02:00
Steven Wroblewski	51bfd1718b	fix(core): enforce CharacterData compile order and remove ClassDB type lookup on export character.gd referenced CharacterData.State as a compile-time constant dict, causing export to fail when character.gd was compiled before character_data.gd (alphabetical order). The preload forces character_data.gd to be compiled first. Changing SubResource type to "Resource" removes the ClassDB lookup for the custom class name during scene export, relying on the explicit script reference instead. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-17 13:11:30 +02:00
Steven Wroblewski	8f416b8999	fix(core): add explicit script reference for CharacterData SubResource in Main.tscn Godot 4 Android export cannot resolve custom class names from the global script cache during scene export. Adding an explicit ExtResource reference to character_data.gd ensures the type is resolved at load time without relying on the class cache. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-17 12:57:39 +02:00
Steven Wroblewski	19d1ec1fe5	fix(core): remove class_name from autoload scripts to prevent singleton conflict Godot 4 throws "Class hides an autoload singleton" when a script declares class_name with the same name as its registered autoload. Removed class_name from AudioManager and RoomNavigator — both are accessible globally via their autoload name without it. Also ignores Godot-generated *.uid files.
