GDScript Advanced

Production-grade GDScript depth — for shipping games, not for learning the language. Pair with gdscript-patterns for fundamentals.

Related skills: gdscript-patterns for language fundamentals, godot-optimization for engine-side perf work, godot-debugging for runtime diagnosis, csharp-godot for the C# alternative.

Intent: This skill is GDScript-only by design (allowlisted). C# users should read csharp-godot. Adding C# parity here would undermine the audience split.

1. When to reach for advanced GDScript

You're past gdscript-patterns when:

• You're hitting a profiler bottleneck and need to know which idioms are fast
• You're writing editor tools and need @tool lifecycle correctness
• You're seeing await deadlocks or Callable lifetime bugs
• You need metaprogramming (calling functions by name, dynamic dispatch) without footguns
• You're shipping a real game and want to avoid the patterns that look fine but break under load

This skill assumes you already know typed parameters, @onready, await, match, and lambdas (covered in gdscript-patterns).
