Godot GDScript Patterns
Production patterns for Godot 4.x game development with GDScript, covering architecture, signals, scenes, and optimization.
When to Use This Skill
- Building games with Godot 4
- Implementing game systems in GDScript
- Designing scene architecture
- Managing game state
- Optimizing GDScript performance
- Learning Godot best practices
Core Concepts
1. Godot Architecture
Node: Base building block
├── Scene: Reusable node tree (saved as .tscn)
