我正在制作自己的游戏。我已经制作了启动画面和主菜单。我在我的菜单中制作了一个按钮“播放”，但我无法将它链接到我的主游戏，但我可以将它链接到其他类(class)。
这是我无法打开的类的代码:

这是菜单类:

最佳答案
public class MyGdxGame extends Game{
public static MenuScreen menuScreen;
public static GameScreen gameScreen;
@Override
public void create(){
menuScreen = new MenuScreen(this);
gameScreen = new GameScreen (this);
setScreen(menuScreen);
}
}
这是菜单界面
public class MenuScreen implements Screen{
MyGdxGame game;
public MenuScreen(MyGdxGame game){
this.game = game;
}
////////////when you want to change screen type game.setScreen(game.gameScreen)
...........
...........
}
这是GameScreen
public class GameScreen implements Screen{
...........
...........
...........
}
这是一个简单的例子，尝试在你的代码中做同样的事情。
这是一个很好的教程
