我有一个flappy bird示例的游戏/测试类，我有一个登录屏幕，点击这个屏幕类中的JButton“loggin”我想调用下面的flappyBird类。
我试过这样的事但没有运气
if(event == jButtonLogin){
this.dispose();
FlappyBird bird = new FlappyBird();
bird.setVisible();
//因为它里面有Jframe我虽然这个逻辑可行。
如果有人能以正确的方式指出我，请
public class FlappyBird implements ActionListener, MouseListener, KeyListener {
//private static final long serialVersionUID = 1L;
public static FlappyBird flappyBird; //creating a static flappybird so it can be acessed within main
public final int WIDTH = 800, HEIGHT = 600; //scren size of the game
public int highScore = 0;
public Renderer renderer;

答案 0 :(得分：0)
考虑调查布局管理器以实现基于状态的游戏的行为。
Ex：在你的main方法中，不是调用新的FlappyBird（）而是调用new Login（）之类的东西。
在创建Login对象时要小心 - 你不希望通过“打开”和创建第二个JFrame来重新发明轮子（一个不受欢迎的创可贴解决方案可以通过隐藏JFrame来完成，但这不是你想要什么）。
相反，正如MadProgrammer暗示的那样 - 布局管理员可以立即允许您的应用程序交换环境。一些重组是为了完成这个设计，但总的来说它更模块化，可扩展（如果你想包括一个选项页面），更多面向OOP。
最终，从Login对象中，用户将能够单击将布局交换到Play布局的按钮（这是所有FlappyBird内容的位置）。
