Android Game Programming by Example

Drawing at 60 + FPS

In three simple steps, we will be able to glimpse our spaceship:

• Add a SpaceShip object to the GameManager member variables:

  private boolean playing = false;
  
    // Our first game object
       SpaceShip ship;
  
       int screenWidth;

• Add a call to the new SpaceShip() to the createObjects method:

  private void createObjects() {
          
    // Create our game objects
    // First the ship in the center of the map
       gm.ship = new SpaceShip(gm.mapWidth / 2, gm.mapHeight / 2);
  }

• Add the call to draw the spaceship in each frame in the draw method of AsteroidsRenderer:

  // Start drawing!
  // Draw the ship
  gm.ship.draw(viewportMatrix);
  

Run the game and see the output:
