## Expert Techniques & Optimizations
### 1. Alt-Tab-Pause (Stuck Input Guard)
When a game loses focus, the OS may intercept "key up" events, leaving Godot's `Input` state stuck. Use `NOTIFICATION_APPLICATION_FOCUS_OUT` to pause the game and reset input logic.
```gdscript
func _notification(what: int) -> void:
match what:
NOTIFICATION_APPLICATION_FOCUS_OUT:
get_tree().paused = true
# Optional: Manually release critical actions
Input.action_release("move_forward")
NOTIFICATION_APPLICATION_FOCUS_IN:
get_tree().paused = false2. Social Integrations (GDExtension)
For Discord-RPC or Vapor network pipes, use GDExtension to bind native shared libraries (.dll, .so, .dylib) to Godot at runtime. This keeps the engine core small while enabling expert-level social features.
