Utilisation de "godot-4-migration". Convert this Godot 3 code to Godot 4: export var speed = 10
RĂ©sultat attendu:
In Godot 4, use the @export annotation:
```gdscript
@export var speed: int = 10
```
You can also add type hints and inspector hints:
```gdscript
@export_range(1, 100) var speed: int = 10
```
Utilisation de "godot-4-migration". How do I use Tweens in Godot 4?
RĂ©sultat attendu:
The Tween node is deprecated. Use create_tween() method:
```gdscript
var tween = create_tween()
tween.tween_property($Sprite, 'position', Vector2(100, 100), 1.0)
tween.parallel().tween_property($Sprite, 'modulate:a', 0.0, 1.0)
```

Bonnes pratiques
- Use @export_range, @export_file, and other @export annotations for better editor integration
- Type all variables with explicit type hints for performance gains in GDScript 2.0
- Use super() to call parent methods instead of the old .method_name() syntax
Éviter
- Do not use emit_signal('name') when you can use name.emit() with the signal object
- Do not use string-based signal connections like connect('pressed', self, '_handler')
- Do not use yield() for coroutines - use await instead in Godot 4
