Libgdx屏幕混乱-Java 学习之路

-1

你好，这是我第一次在这里发帖，对编码比较新 . 我一直在玩java和libgdx一两个月，我对屏幕上的一件事感到困惑 .

如果我有一个GameScreen类在玩游戏时处于活动状态，然后想要暂时切换到另一个屏幕进行库存或暂停屏幕或某事，如果我让游戏切换回游戏屏幕，那么似乎一切都重置并且是新的比赛开始 . 什么是确保屏幕重新加载的正确方法是什么？

如果您希望在后台保持屏幕处于活动状态（如您所述），则需要确保将游戏初始化代码分开，以便仅在启动新级别时调用它 . 有一百万种方法可以做到这一点 . 这是一个例子：

public class MyGameScreen {

    public MyGameScreen (){
        //load textures and sounds here if you aren't managing them somewhere else.

        startNewGameRound();
    }

    @Override
    public void show (){
        //this is only for stuff you need to reset every time the screen comes back. 
        //Generally, you would undo stuff that you did in `hide()`.
    }

    public void startNewGameRound (){
        //Reset all your variables and reinitialize state for a new game round.
        //This is called in the constructor for first time setup, and then it 
        //can also be called by a button anywhere that starts a new round.
        //But do not load textures and sounds here. Do that in the constructor
        //so it only happens once.
    }

}

然后在您的Game类中，您还需要确保保留游戏屏幕实例并重复使用它 .

不要这样做：

setScreen(new MyGameScreen());

改为：

//member variable:
private MyGameScreen myGameScreen;

//In some method:
if (myGameScreen == null)
    myGameScreen = new MyGameScreen();
setScreen(myGameScreen);
