Project Directory Structure

Separate framework, resources (by type), and game code. Do not mix them.

├── audio/         # Audio assets
├── image/         # Image assets
├── config/        # CSV/JSON tables (optional)
├── shader/        # Custom shaders (optional)

├── 3d/            # Models, meshes, materials, animations
└── …              # Other misc assets as needed

Other resource roots (add when needed): config/, shader/.

Game code — scene/ and script/

scene/

├── main/
├── gameplay/
└── ui/

script/
├── autoload/      # Game Autoloads (after GodotFramework)
├── core/          # Constants, ResPath, shared base classes
├── data/          # Resource classes and .tres instances

└── network/       # Packets and codec (zfoo Router)

GDScript (this project)

• Types: Use explicit types on function signatures and return values (-> void, etc.). Use the class_name type when a class has one. Prefer := for locals to lock in the inferred type at declaration; use var x = ... only when you need Variant or mixed types.
• Docs: Use ## comments for scene entry points or complex logic. Match the tone of nearby files.
• Nodes: Prefer @onready var name: Type = $Path.
• Trailing pass: If a function has no return statement, end the body with pass.
