Migration instructions

To specify start and end opacities for ColorEffect use the optional named
parameters opacityFrom and opacityTo. So offset.dx should be set as opacityFrom
and offset.dy should be set as opacityTo.

• If you are using DragUpdateEvent events, the devicePosition, canvasPosition,
  localPosition, and delta are deprecated as they are unclear.
• Use xStartPosition to get the position at the start of the drag event ("from").
• Use xEndPosition to get the position at the end of the drag event ("to").
• If you want the delta, use localDelta. it now already considers the camera
  zoom. No need to manually account for that.
• Now you keep receiving drag events for the same component even if the
  drag event leaves the component (breaking)

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.
