Implement Feature

Phase 2 — Plan

Before creating files, plan the implementation:

1. List all files that need to be created or modified
2. Define the node hierarchy for each new scene
3. Define the public API (signals, exported vars, public methods) for each script
4. Identify integration points — how this feature connects to existing systems
5. Identify resources — what custom Resource types are needed for data

Present the plan to the user before proceeding.

Phase 3 — Implement

Create files in this order:

1. Resources first — custom Resource classes that define data structures
2. Core systems — manager scripts, state machines, utility classes
3. Scenes — .tscn scene files with node hierarchies
4. Scripts — .gd scripts attached to scenes
5. Integration — wire the feature into existing scenesscripts via signals

Code Quality Requirements (from gemini.md)

• Use tabs for indentation
• Use static typing everywhere: var health: int = 0, func heal(amount: int) -> void:
• Use := only when type is obvious: var direction := Vector3(1, 2, 3)
• Use @export for inspector-exposed variables
• Use @onready for node references: @onready var bar: ProgressBar = $UI/Bar
• Use and/or/not over &&/||/!
• Use double quotes for strings
• Trailing commas in multiline arrays, dicts, enums
• Two blank lines between functions
• Lines under 100 characters
• Signals in past tense (health_changed, died, item_collected)
• Private members prefixed with _
• One script per scene node (composition over inheritance)
• Prefer signals over direct method calls for decoupled communication

Script Code Order

01. @tool, @icon, @static_unload
02. class_name
03. extends
04. ## doc comment
05. signals
06. enums
07. constants
08. static variables
09. @export variables
10. remaining regular variables
11. @onready variables
12. _init() -> _ready() -> _process() -> _physics_process() -> other virtual methods
13. public methods
14. private methods (prefixed with _)
15. inner classes

Phase 4 — Verify

After implementation:

1. Check all file paths — ensure scenes reference correct script paths
2. Check signal connections — ensure all signals are connected (either in code or noted for scene editor)
3. Check autoload requirements — note if any singletons need registration in project.godot
4. Check for circular dependencies — ensure no script directly references something that references it back
5. List what can't be done in code — some things (collision shapes, sprite assignment, tilemap painting) require the Godot editor

Phase 5 — Report

Provide a comprehensive summary:

1. Files createdmodified with full paths
2. Architecture overview — how the pieces connect
3. Public APIs — signals, methods, exports for each key script
4. Editor tasks — what the user needs to do in the Godot editor (assign sprites, configure collision shapes, paint tilemaps, etc.)
5. Testing suggestions — how to verify the feature works
6. Future enhancements — what could be improved or extended later
