# Sprint 14 — Garden Party 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:** Complete the GardenParty scene with GiftBox auto-reset, Balloon pop/respawn, Cake cut/reset, and chair snap points for characters.

**Architecture:** Three independent state-machine objects (`gift_box.gd` extended, `balloon.gd` new, `cake.gd` new) following the existing project pattern — each with a `State` enum, tween-driven animations, and `_on_X_complete()` callbacks testable without tweens. `GardenParty.tscn` is updated to wire balloon scripts and add the Cake and chair nodes. No new autoloads or base classes.

**Tech Stack:** GDScript 4 (static types), GUT v9.6.0, Godot 4.6.2.

---

### Task 1: GiftBox RESETTING state

**Files:**
- Modify: `scripts/objects/gift_box.gd`
- Modify: `test/unit/test_gift_box.gd`

The `OPEN` state is removed. `RESETTING` replaces it: gift fades in, waits 3 s, then the lid closes and the box resets.

- [ ] **Step 1: Update test file**

Replace the full contents of `test/unit/test_gift_box.gd` with:

```gdscript
## Tests for GiftBox — CLOSED/OPENING/RESETTING state machine transitions.
extends GutTest

var _box: GiftBox


func before_each() -> void:
	_box = preload("res://scenes/objects/GiftBox.tscn").instantiate() as GiftBox
	add_child_autofree(_box)


func test_initial_state_is_closed() -> void:
	assert_eq(_box._state, GiftBox.State.CLOSED)


func test_ready_hides_gift_node() -> void:
	var gift: Node2D = _box.get_node("Gift") as Node2D

func test_input_ignored_when_state_is_opening() -> void:
	_box._state = GiftBox.State.OPENING
	var event: InputEventScreenTouch = InputEventScreenTouch.new()
	event.pressed = true
	event.position = _box.global_position
	_box._input(event)
	assert_eq(_box._state, GiftBox.State.OPENING)


func test_input_ignored_when_state_is_resetting() -> void:
	_box._state = GiftBox.State.RESETTING
	var event: InputEventScreenTouch = InputEventScreenTouch.new()
	event.pressed = true
	event.position = _box.global_position
	_box._input(event)
	assert_eq(_box._state, GiftBox.State.RESETTING)


func test_tap_outside_hitbox_does_not_open() -> void:
	var event: InputEventScreenTouch = InputEventScreenTouch.new()
	event.pressed = true
	event.position = _box.global_position + Vector2(200.0, 200.0)
	_box._input(event)
	assert_eq(_box._state, GiftBox.State.CLOSED)


func test_release_event_does_not_open() -> void:
	var event: InputEventScreenTouch = InputEventScreenTouch.new()
	event.pressed = false
	event.position = _box.global_position
	_box._input(event)
	assert_eq(_box._state, GiftBox.State.CLOSED)


func test_on_reset_complete_transitions_to_closed() -> void:
	_box._state = GiftBox.State.RESETTING
	_box._on_reset_complete()
	assert_eq(_box._state, GiftBox.State.CLOSED)
```

```

Expected: `test_on_lid_opened_transitions_to_resetting` FAIL (State.RESETTING not in enum), `test_input_ignored_when_state_is_resetting` FAIL, `test_on_reset_complete_transitions_to_closed` FAIL.

- [ ] **Step 3: Replace `scripts/objects/gift_box.gd`**

```gdscript

### Task 2: Balloon pop/respawn

**Files:**
- Create: `scripts/objects/balloon.gd`
- Create: `test/unit/test_balloon.gd`

`balloon.gd` is a `Node2D` script (not attached to a scene file — attached directly to nodes in `GardenParty.tscn` in Task 4). Tests use `Balloon.new()`.

- [ ] **Step 1: Write failing test**

Create `test/unit/test_balloon.gd`:

```gdscript
## Tests for Balloon — state machine transitions.
extends GutTest

var _balloon: Balloon


func before_each() -> void:
	_balloon = Balloon.new()
	add_child_autofree(_balloon)


func test_initial_state_is_idle() -> void:
	assert_eq(_balloon._state, Balloon.State.IDLE)


func test_start_pop_transitions_to_popping() -> void:
	_balloon._start_pop()
	assert_eq(_balloon._state, Balloon.State.POPPING)


func test_on_pop_complete_transitions_to_popped() -> void:
	_balloon._on_pop_complete()
	assert_eq(_balloon._state, Balloon.State.POPPED)


func test_on_respawn_complete_transitions_to_idle() -> void:
	_balloon._state = Balloon.State.RESPAWNING
	_balloon._on_respawn_complete()
	assert_eq(_balloon._state, Balloon.State.IDLE)
```

- [ ] **Step 2: Run → verify FAIL**

```bash
"F:/Development/_tools/Godot_v4.6.2-stable_win64/Godot_v4.6.2-stable_win64.exe" --headless -s res://addons/gut/gut_cmdln.gd -gdir=res://test/ -gexit --path "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-14-garden-party"
```

Expected: all 4 balloon tests FAIL — `Balloon` class not found.

- [ ] **Step 3: Create `scripts/objects/balloon.gd`**

```gdscript
## Balloon — tap to pop, auto-respawns after a delay.
class_name Balloon extends Node2D

enum State { IDLE, POPPING, POPPED, RESPAWNING }

const POP_DURATION: float = 0.15
const RESPAWN_DURATION: float = 0.30
const RESPAWN_DELAY: float = 5.0
const BUTTON_HALF_SIZE: float = 20.0

var _state: State = State.IDLE


func _input(event: InputEvent) -> void:
	if _state != State.IDLE:
		return
	if not event is InputEventScreenTouch:
		return
	var touch: InputEventScreenTouch = event as InputEventScreenTouch
	if not touch.pressed:
		return
	var local: Vector2 = to_local(touch.position)
	if abs(local.x) > BUTTON_HALF_SIZE or abs(local.y) > BUTTON_HALF_SIZE:
		return
	_start_pop()


func _start_pop() -> void:
	AudioManager.play_sfx("object_tap")
	_state = State.POPPING
	var tween: Tween = create_tween()
	tween.set_ease(Tween.EASE_IN)
	tween.set_trans(Tween.TRANS_BACK)
	tween.tween_property(self, "scale", Vector2.ZERO, POP_DURATION)
	tween.tween_callback(_on_pop_complete)


func _on_pop_complete() -> void:
	_state = State.POPPED
	var tween: Tween = create_tween()
	tween.tween_interval(RESPAWN_DELAY)
	tween.tween_callback(_start_respawn)


func _start_respawn() -> void:
	_state = State.RESPAWNING
	var tween: Tween = create_tween()
	tween.set_ease(Tween.EASE_OUT)
	tween.set_trans(Tween.TRANS_BACK)
	tween.tween_property(self, "scale", Vector2.ONE, RESPAWN_DURATION)
	tween.tween_callback(_on_respawn_complete)


func _on_respawn_complete() -> void:
	_state = State.IDLE
```

- [ ] **Step 4: Run → verify all pass**

```bash
"F:/Development/_tools/Godot_v4.6.2-stable_win64/Godot_v4.6.2-stable_win64.exe" --headless -s res://addons/gut/gut_cmdln.gd -gdir=res://test/ -gexit --path "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-14-garden-party"
```

Expected: all tests pass including 4 new balloon tests.

- [ ] **Step 5: Commit**

```bash
git -C "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-14-garden-party" add scripts/objects/balloon.gd test/unit/test_balloon.gd
git -C "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-14-garden-party" commit -m "feat(sprint-14): add Balloon pop/respawn state machine"
```

### Task 3: Cake cut/reset

**Files:**
- Create: `scripts/objects/cake.gd`
- Create: `test/unit/test_cake.gd`

`cake.gd` is attached directly to a `Node2D` in `GardenParty.tscn` (Task 4). It looks for a `"Slice"` child node.

- [ ] **Step 1: Write failing test**

Create `test/unit/test_cake.gd`:

```gdscript
## Tests for Cake — state machine transitions.
extends GutTest

var _cake: Cake


func before_each() -> void:
	_cake = Cake.new()
	add_child_autofree(_cake)


func test_initial_state_is_whole() -> void:
	assert_eq(_cake._state, Cake.State.WHOLE)


func test_start_cutting_transitions_to_cutting() -> void:
	_cake._start_cutting()
	assert_eq(_cake._state, Cake.State.CUTTING)


func test_on_cut_complete_transitions_to_cut() -> void:
	_cake._on_cut_complete()
	assert_eq(_cake._state, Cake.State.CUT)


func test_on_reset_complete_transitions_to_whole() -> void:
	_cake._state = Cake.State.RESETTING
	_cake._on_reset_complete()
	assert_eq(_cake._state, Cake.State.WHOLE)
```

- [ ] **Step 2: Run → verify FAIL**

```bash
"F:/Development/_tools/Godot_v4.6.2-stable_win64/Godot_v4.6.2-stable_win64.exe" --headless -s res://addons/gut/gut_cmdln.gd -gdir=res://test/ -gexit --path "F:/Development/_gameDev/Cozypaw-Hospital/.worktrees/sprint-14-garden-party"
```

Expected: all 4 cake tests FAIL — `Cake` class not found.

- [ ] **Step 3: Create `scripts/objects/cake.gd`**

```gdscript
## Cake — tap to cut a slice, slice auto-respawns after a delay.
class_name Cake extends Node2D

enum State { WHOLE, CUTTING, CUT, RESETTING }

const CUT_DURATION: float = 0.3
const RESET_DURATION: float = 0.3
const RESET_DELAY: float = 3.0
const BUTTON_HALF_WIDTH: float = 40.0
const BUTTON_HALF_HEIGHT: float = 20.0

var _state: State = State.WHOLE


func _input(event: InputEvent) -> void:
	if _state != State.WHOLE:
		return
	if not event is InputEventScreenTouch:
		return
	var touch: InputEventScreenTouch = event as InputEventScreenTouch
	if not touch.pressed:
		return
	var local: Vector2 = to_local(touch.position)
	if abs(local.x) > BUTTON_HALF_WIDTH or abs(local.y) > BUTTON_HALF_HEIGHT:

	_start_cutting()


func _start_cutting() -> void:

	var tween: Tween = create_tween()
	if slice != null:

```

- [ ] **Step 4: Run → verify all pass**

### Task 4: GardenParty.tscn scene update

**Files:**
- Modify: `scenes/rooms/home/GardenParty.tscn`

Changes: add `balloon.gd` + `cake.gd` ext_resources, convert Balloon nodes from `ColorRect` to `Node2D` + Body child (required because `balloon.gd extends Node2D`, not `ColorRect`), replace `GiftBox3` with `Cake` node, add `ChairLeft`/`ChairRight` ColorRects as visual seat indicators.

No tests for scene structure — verify visually on device.

- [ ] **Step 1: Replace `scenes/rooms/home/GardenParty.tscn`**
