I am working on a side shooter with Flame, and would like the screen to shake when the player is hit by a bullet.

I have found this post: /a/76698880/1843141

I implemented it as follows but that’s not working:

class MyGame extends FlameGame {
  @override
  Future<void> onLoad() async {
    await Flame.device.fullScreen();
    await Flame.device.setLandscape();

    ...
    
    camera = CameraComponent.withFixedResolution(
      world: world,
      width: 800,
      height: 600,
    );
    add(camera);
    
    ...
  }

  // I call this when the player's sprite detects a collision
  void shakeScreen() {
    camera.viewfinder.add(
      MoveEffect.by(
        Vector2(30, 30),
        NoiseEffectController(
          duration: 0.2,
          noise: PerlinNoise(frequency: 40),
        ),
      ),
    );
  }
  
  ...
}

When I use the same method on a sprite, it shakes ¯(ツ)/¯
