java - 如何在处理中重新启动游戏？

Question

所以我想编写一个处理游戏，你尝试用篮球圈接住下落的球。一切都很顺利，直到某个时候，当你赢或输并按下“重新开始”时，游戏将不会重新开始。这是我的 setup() 方法(仅初始化变量的相关部分):

void setup() {
    game = new Game();
    scr = new SplashScreen();
    gameBackground = new Image();
    background = new DynamicBackground();
    button = new Rect();

    /* Music set */
    intro = new Music();
    lifeMusic = new Music();
    failMusic = new Music();

    /* Ball and ring set */
    ball = new Image();
    ring = new Image();

    /* Life points set */
    life1 = new Image();
    life2 = new Image();
    life3 = new Image();
    life4 = new Image();
    failCount = 3;
    sucCount =0;
    winStr = "YOU WON!";
    gameOverStr = "GAME OVER";
    restartStr = "Resetart";

    flag = true;
    win = new Text();
    gameOver = new Text();
    restart = new Text();

    size(710, 490);

    .....
}

这是我的mousePressed方法:

void mousePressed(){
    if(mouseX>button.x && mouseX <button.x+button.width && mouseY>button.y && mouseY <button.y+button.height){
        loop();
        setup();
    }
}

如你所见，我尝试做 noLoop()当游戏结束时，当您按下我称为“重新启动”的按钮时，它将 loop()和setup() .

为什么我按“重新启动”时游戏卡住了？

setup()由内部回调调用。它无意于调用setup。请注意，在设置中窗口已初始化 (size(710, 490);)。 setup 的调用导致系统挂起。

将静态对象的初始化保留在setup中，但将所有动态对象(“移动”对象)的初始化移至init函数。在 setup 和 mousePressed 中调用此函数:

void init() {
    game = new Game();
    scr = new SplashScreen();
    gameBackground = new Image();
    background = new DynamicBackground();
    button = new Rect();

    /* Ball and ring set */
    ball = new Image();
    ring = new Image();

    // ...
}

void setup() {

    size(710, 490);

    // init static objects

    /* Music set */
    intro = new Music();
    lifeMusic = new Music();
    failMusic = new Music();

    // init dynamic objects
    init();
}

void mousePressed(){
    if(mouseX>button.x && mouseX <button.x+button.width && mouseY>button.y && mouseY <button.y+button.height){
        init();
        loop();
    }
}
