java – 如何在libgdx scene2d上拖放演员？

请尝试帮助我使用我自己的架构.

public class MyGame implements ApplicationListener 
{
    Stage stage;
    Texture texture;
    Image actor;

    @Override
    public void create() 
    {       
        texture = new Texture(Gdx.files.internal("actor.png"));
        Gdx.input.setInputProcessor(stage);
        stage = new Stage(512f,512f,true);

        actor = new Image(texture);
        stage.addActor(actor);
    }

    @Override
    public void render() 
    {       
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
        stage.draw();
    }
}
