Making a Scene - Learning LibGDX Game Development - page 177

We have to make some minor changes to the CameraHelper class in order to make
the switch from using Sprite objects to AbstractGameObject .
Remove the following import line from CameraHelper :
import com.badlogic.gdx.graphics.g2d.Sprite;
Next, add this import line in CameraHelper :
import com.packtpub.libgdx.canyonbunny.game.objects.
AbstractGameObject;
Now, change the code in CameraHelper :
private AbstractGameObject target;
public void update (float deltaTime) {
if (!hasTarget()) return;
position.x = target.position.x + target.origin.x;
position.y = target.position.y + target.origin.y;
}
public void setTarget (AbstractGameObject target) {
this.target = target;
}
public AbstractGameObject getTarget () {
return target;
}
public boolean hasTarget (AbstractGameObject target) {
return hasTarget() && this.target.equals(target);
}
Next, add the following code in WorldRenderer :
private void renderWorld (SpriteBatch batch) {
worldController.cameraHelper.applyTo(camera);
batch.setProjectionMatrix(camera.combined);
batch.begin();
worldController.level.render(batch);
batch.end();
}
Then, remove the renderTestObjects() method from WorldRenderer .
