public static Texture shipTexture ;

public static Texture invaderTexture ;
public static Vertices3 shotModel ;
public static Vertices3 shieldModel ;
We use Texture instances and Vertices3 instances to store the models and textures of our
game's objects. We use an Animation(0.1f, instance to hold the frames of the explosion animation.
public static Music music ;
public static Sound clickSound ;
public static Sound explosionSound ;
public static Sound shotSound ;
We use a Music instance and a few Sound instances to store our game's audio.

The load() method starts off by creating the UI-related stuff. It's just some texture loading and
region creation, as usual.

}
}
