prepare method

@override @mustCallSuper void prepare(Component parent)

Prepares the Component to be added to a parent, and if there is an ancestor that is a FlameGame that game will do necessary preparations for this component. If there are no parents that are a Game false will be returned and this will run again once an ancestor or the component itself is added to a Game.

Implementation

@override
@mustCallSuper
void prepare(Component parent) {
  super.prepare(parent);

  if (isPrepared) {
    final parentGame = findParent<FlameGame>();
    assert(
      parentGame is HasCollidables,
      'You can only use the HasHitboxes/Collidable feature with games that '
      'has the HasCollidables mixin',
    );
  }
}
