Android Invaders: The Grand Finale - Beginning Android Games - page 590

Next, we create the Texture for the explosion animation, along with the TextureRegions for
each frame and the Animation instance. We simply loop from the top left to the bottom right in
64-pixel increments, and create one TextureRegion per frame. We then feed all the regions to an
Animation instance, whose frame duration is 0.1 second.
shipTexture = new Texture(game, "ship.png", true );
shipModel = ObjLoader. load (game, "ship.obj");
invaderTexture = new Texture(game, "invader.png", true );
invaderModel = ObjLoader. load (game, "invader.obj");
shieldModel = ObjLoader. load (game, "shield.obj");
shotModel = ObjLoader. load (game, "shot.obj");
Next, we load the models and textures for the ship, the invaders, the shield blocks, and the
shots. This is pretty simple with our mighty ObjLoader , isn't it? Note that we use mipmapping for
the Textures .
music = game.getAudio().newMusic("music.mp3");
music .setLooping( true );
music .setVolume(0.5f);
if (Settings. soundEnabled )
music .play();
clickSound = game.getAudio().newSound("click.ogg");
explosionSound = game.getAudio().newSound("explosion.ogg");
shotSound = game.getAudio().newSound("shot.ogg");
}
Here, we load the music and sound effects for our game. The reference to the Settings class is
essentially the same as in Super Jumper and Mr. Nom. This method will be called once when our
game is started in the AndroidInvaders class that we'll implement in a minute. Once all assets
are loaded, we can forget about most of them, except for the Textures , which we need to reload
if the game is paused and then resumed.
public static void reload() {
background .reload();
items .reload();
explosionTexture .reload();
shipTexture .reload();
invaderTexture .reload();
if (Settings. soundEnabled )
music .play();
}
That's where the reload() method comes in. We call this method in the AndroidInvaders.
onResume() method so that our textures will be reloaded and the music will be unpaused.
public static void playSound(Sound sound) {
if (Settings. soundEnabled )
sound.play(1);
}
}
