Migration instructions #

In this release the old camera system was renamed to oldCamera and replaced by a default World and a CameraComponent which is now named camera.

To migrate from the old system:

  1. Instead of adding the components directly to your game with add, add them to the world, this will make the CameraComponent responsible for rendering them instead of the game directly.

    world.add(yourComponent);

  2. (Optional) If you want to add a HUD component, instead of using PositionType, add the component as a child of the viewport.

    cameraComponent.viewport.add(yourHudComponent);

  3. (Optional) If you want to have a specificly set up CameraComponent in your game from the start you can pass in a camera to the constructor.

    class MyGame extends FlameGame {
  MyGame() 
      : super(
          camera: CameraComponent.withFixedResolution(
            width: 800,
            height: 600,
          ),
        );

  4. (Optional) A lot of the time it is no longer necessary to extend FlameGame, you can instead build your game or level by extending the World and pass it in to the FlameGame.

    runApp(
  GameWidget(game: FlameGame(world: MyWorld()),
);

class MyWorld extends World with TapCallbacks {
  @override
  Future<void> onLoad() async {
    // Load your components
  }

  @override
  void onTapDown(TapDownEvent event) {
    print(event.localPosition); // Position of the tap in the world
  }
}

Migration instructions #

In the future (maybe as early as v1.9.0) this camera will be removed, please use the CameraComponent instead.

This is the simplest way of using the CameraComponent:

  1. Add variables for a CameraComponent and a World to your game class

    final world = World();
late final CameraComponent cameraComponent;

  2. In your onLoad method, initialize the cameraComponent and add the world to it.

    @override
void onLoad() {
  cameraComponent = CameraComponent(world: world);
  addAll([cameraComponent, world]);
}

  3. Instead of adding the root components directly to your game with add, add them to the world.

    world.add(yourComponent);

  4. (Optional) If you want to add a HUD component, instead of using PositionType, add the component as a child of the viewport.

    cameraComponent.viewport.add(yourHudComponent);

Migration instructions #

If you have components that rely on receiving onGameResize calls before they load, then you can retrieve the game's size in onLoad manually via findGame()!.size.

The HasDraggableComponents mixin is now empty & deprecated. If your game used this mixin overriding its methods onDragStart, onDragUpdate, etc -- then they will no longer work. If you want to receive drag events at the top level of the game, then simply add a DragCallbacks component to the top level of the game.

The HasTappableComponents mixin is now empty & deprecated. If your game used this mixin overriding its methods onTapDown, onTapUp, etc -- then they will no longer work. If you want to receive tap events at the top level of the game, then simply add a TapCallbacks component to the top level of the game.
