代码示例

代码示例来源：origin: libgdx/libgdx

@Override
public void create () {
  // create a stage and a camera controller so we can pan the view.
  stage = new Stage();;
  camController = new OrthoCamController((OrthographicCamera)stage.getCamera()); // we know it's an ortho cam at this point!
  Gdx.input.setInputProcessor(camController);
  // load a dummy texture
  texture = new Texture(Gdx.files.internal("data/badlogicsmall.jpg"));
  // populate the stage with some actors and groups.
  for (int i = 0; i < 5000; i++) {
    Actor img = new CullableActor("img" + i, texture, (OrthographicCamera)stage.getCamera());
    img.setX((float)Math.random() * 480 * 10);
    img.setY((float)Math.random() * 320 * 10);
    stage.addActor(img);
  }
  // we also want to output the number of visible actors, so we need a SpriteBatch and a BitmapFont
  batch = new SpriteBatch();
  font = new BitmapFont(Gdx.files.internal("data/arial-15.fnt"), false);
}
