You’ll use what you’ve learned during this course so far to define and add a new component called Saucer. It will be positioned randomly in the game’s screen like Meteorite.

Solution

Saucer

Open lib/components/saucer.dart. Define a class that extends SpriteComponent.

import 'package:flame/components.dart';

class Saucer extends SpriteComponent {
}

static const double saucerWidth = 128.0;
static const double saucerHeight = 64.0;
static final Sprite saucerSprite = loadMeteormaniaSprite(0, 0, 128, 64);
static final Vector2 saucerSize = Vector2(saucerWidth, saucerHeight);

Saucer() : super(sprite: saucerSprite, size: saucerSize);

MeteormaniaGame

Now let’s add it to _world. Back in MeteormaniaGame, in addEnemies function, create a new Saucer.

final (saucerX, saucerY) = randomPosition(
  Saucer.saucerWidth * GameConstants.saucerMaxMovementFactor,
  Saucer.saucerHeight * GameConstants.saucerMaxMovementFactor,
  Spaceship.spaceshipSize.toSize(),
);
final saucer = Saucer()
  ..anchor = Anchor.center
  ..position = Vector2(saucerX, saucerY);

Uyk, bos’y edd om du _mixry

_world
  ..add(saucer)
  ..addAll(meteorites);
