Now that we have implemented all the game objects of Canyon Bunny, we can complete the level loader.
First, add the following import lines to Level:
import com.packtpub.libgdx.canyonbunny.game.objects.BunnyHead; import com.packtpub.libgdx.canyonbunny.game.objects.Feather; import com.packtpub.libgdx.canyonbunny.game.objects.GoldCoin;
Additionally, add these three member variables to the same class:
public BunnyHead bunnyHead; public Array<GoldCoin> goldcoins; public Array<Feather> feathers;
After this, modify the init() and render() methods:
private void init (String filename) {
// player character
bunnyHead = null;
// objects
rocks = new Array<Rock>();
goldcoins = new Array<GoldCoin>();
feathers = new Array<Feather>();
// load image file that represents the level data
Pixmap pixmap = new Pixmap(Gdx.files.internal(filename));
// scan pixels from top-left to bottom-right
int lastPixel = -1;
for (int pixelY = 0; pixelY < pixmap.getHeight(); pixelY++) {
for (int pixelX = 0; pixelX < pixmap.getWidth(); pixelX++) {
...
// rock
else if (BLOCK_TYPE.ROCK.sameColor(currentPixel)) {
...
}
// player spawn point
else if
(BLOCK_TYPE.PLAYER_SPAWNPOINT.sameColor(currentPixel)) {
obj = new BunnyHead();
offsetHeight = -3.0f;
obj.position.set(pixelX,baseHeight * obj.dimension.y + offsetHeight);
bunnyHead = (BunnyHead)obj;
}
// feather
else if(BLOCK_TYPE.ITEM_FEATHER.sameColor(currentPixel)) {
obj = new Feather();
offsetHeight = -1.5f;
obj.position.set(pixelX,baseHeight * obj.dimension.y + offsetHeight);
feathers.add((Feather)obj);
}
// gold coin
else if
(BLOCK_TYPE.ITEM_GOLD_COIN.sameColor(currentPixel)) {
obj = new GoldCoin();
offsetHeight = -1.5f;
obj.position.set(pixelX,baseHeight * obj.dimension.y + offsetHeight);
goldcoins.add((GoldCoin)obj);
}
// unknown object/pixel color
else {
...
}
lastPixel = currentPixel;
}
}
...
}This code adds the actors to the level loading process in the init() method. Next, make the following changes to the render() method:
public void render (SpriteBatch batch) {
// Draw Mountains
mountains.render(batch);
// Draw Rocks
for (Rock rock : rocks)
rock.render(batch);
// Draw Gold Coins
for (GoldCoin goldCoin : goldcoins)
goldCoin.render(batch);
// Draw Feathers
for (Feather feather : feathers)
feather.render(batch);
// Draw Player Character
bunnyHead.render(batch);
// Draw Water Overlay
waterOverlay.render(batch);
// Draw Clouds
clouds.render(batch);
}Then, add the following lines to Level:
public void update (float deltaTime) {
bunnyHead.update(deltaTime);
for(Rock rock : rocks)
rock.update(deltaTime);
for(GoldCoin goldCoin : goldcoins)
goldCoin.update(deltaTime);
for(Feather feather : feathers)
feather.update(deltaTime);
clouds.update(deltaTime);
}We added the new actors to the render() method and created a new update() method so that we can collectively update all the game world objects in a level in one call.
Finally, modify the update() method of WorldController as the following listings:
public void update (float deltaTime) {
handleDebugInput(deltaTime);
level.update(deltaTime);
cameraHelper.update(deltaTime);
}These changes makes sure that all the game objects contained within the level will be updated when the update() method of WorldController is called.
