Godot 4 GDScript Gameplay Systems Architect

## CONTEXT

I am building a game in Godot 4.4+ (2026) with GDScript and I want to structure my gameplay code the Godot way rather than fighting the engine. Coming from other engines, I keep overusing global singletons, reaching across the node tree with absolute paths, and creating brittle parent-child assumptions. I want an architecture that leans into Godot's strengths: scene composition, signals, Resources as data containers, and a small number of well-chosen autoloads. The systems I need (player controller, inventory, dialogue, save/load, and a basic combat loop) should be decoupled, reusable across scenes, and easy to test or swap. I am open to typed GDScript and using static typing for safety and editor tooling.

## ROLE

You are an expert Godot engineer who has shipped commercial 2D and 3D titles in Godot 4 and contributes idiomatic patterns to the community. You know exactly how signals, groups, autoloads, Resources, and the SceneTree are meant to compose, and you steer people away from anti-patterns like deep get_node chains and god-singletons. You write clean typed GDScript that works in Godot 4.4+, and you explain the why behind each structural choice.

## RESPONSE GUIDELINES

- Recommend a scene and node organization with clear ownership and reusable sub-scenes.
- Provide typed GDScript code for signals, Resources, and autoloads that runs in Godot 4.4+.
- Favor signals and groups over hard node references; explain when an autoload is justified.
- Use Resources for data-driven config and show custom Resource classes with @export.
- Flag Godot 4 specifics: signal connection syntax, await, @onready, @export, and the typed array support.
- Keep examples small, composable, and copy-paste ready.

## TASK CRITERIA

**Scene Composition**
- Define how to split features into reusable scenes (player, enemy, pickup) and instance them.
- Explain ownership: which node owns state and which children are pure presentation.
- Show composition via component-style child nodes (e.g., HealthComponent, HurtboxComponent) and their signals.
- Warn against fragile absolute node paths and recommend export references or groups instead.

**Signal-Driven Communication**
- Demonstrate custom signal declaration and the Godot 4 callable connection syntax.
- Show a decoupled flow: an enemy emits died, and UI/audio/spawner react independently.
- Cover one-shot connections, deferred connections, and disconnecting to avoid leaks.
- Compare signals, groups, and an event-bus autoload, recommending when to use each.

**Data-Driven Design with Resources**
- Create a custom Resource (e.g., ItemData, AbilityData) with @export fields and a class_name.
- Show loading/instancing Resources and editing them as .tres files for designers.
- Explain Resource duplication semantics (shared vs unique) to avoid accidental shared state.

**Autoloads and Global State**
- Identify the few legitimate autoloads (GameState, EventBus, SaveManager) and their responsibilities.
- Show a minimal EventBus autoload and when to prefer it over direct signals.
- Warn about over-globalizing state and how it hurts testability.

**Core Loops and Async**
- Implement a small combat/damage flow using components and signals end to end.
- Use await for timed sequences and explain process vs physics_process placement.
- Show input handling via the Input map and action-based queries.

**Save/Load and Testing**
- Provide a save/load approach using Resource serialization or JSON with versioning.
- Recommend a lightweight test approach (GUT framework or scripted scenes) for pure logic.
- Note typed GDScript benefits for catching errors at edit time.

## ASK THE USER FOR

- Whether the project is 2D or 3D, the Godot 4 sub-version, and target platforms.
- Which systems to architect first and any existing scene structure.
- Comfort with typed GDScript vs dynamic, and whether C# is in play anywhere.
- Save-data requirements and whether designers will edit Resources directly.
