添加計分器與分數

Question

進出口正在開發一個處理和Fiducials遊戲。基本上這個遊戲包含提問有關某些國家的問題。每個問題的每個ANS都是一個國家。例如，比薩塔和意大利ASN。用戶必須顯示代表意大利國旗的Fiducial

我得到了倒數計時器運行，但我不能讓它重新啓動一個新的水平時。我們有一個開關的每個級別。

非常感謝您的幫助！

Answer 1

你的計時器的實施表明，它是一個繁忙的計時器。這意味着它依賴於多次調用並檢查它是否晚於其他時間。一個繁忙的計時器的幼稚實施將如下：

while(getTime() < someTime) { do nothing; } 

這種類型的計時器是不好的。你應該嘗試產生一個線程，並使用睡眠。這有點像JavaScript事件處理程序。操作系統在詢問時喚醒線程，然後您可以提醒程序計時器已啓動。如果你同時不需要做任何事情，你可以輕鬆地睡覺你的主體，但是在你跟蹤時間的時候，我覺得你在做某件事。

PS：它顯示你使用Java ...根據你的「進口」。它是否正確？如果是這樣，我可以爲你確定一些參考。

Answer 2

我不完全瞭解定時器在您的程序中發生的位置。我看到一個計時器類：

//Declaring the variable to be used for the timer 
//Timer t; 

但我沒有看到在你的代碼中使用的類。僅適用於時間的函數：

//Below is the timer that will be used 
void time(){ 
    int c; 
    int csec; 
    int climit = 20; //defined for a 20 second countdown 

    c = climit*1000 - millis(); 
    csec = (c/(1000)); 

    if (csec > 0){ 
    text("TIME: "+csec+" secs",1800,50); 
    } else { 
    background(bg); 
    text("TIME: 0 secs",1800,50); 
    text("Time is up!",950,488); 
    } 
} 

我建議不要在處理草圖使用delay()，而是使用當你想在一定時間後發生的不同事件不同的定時器。

我發現Daniel Shiffman的例子非常簡單，對理解如何在Processing中實現定時器很有幫助。 Here是一個面向對象的計時器，在這種情況下對你更有幫助。以下是鏈接中的計時器類：

class Timer { 

    int savedTime; // When Timer started 
    int totalTime; // How long Timer should last 

    Timer(int tempTotalTime) { 
    totalTime = tempTotalTime; 
    } 

    // Starting the timer 
    void start() { 
    // When the timer starts it stores the current time in milliseconds. 
    savedTime = millis(); 
    } 

    // The function isFinished() returns true if 5,000 ms have passed. 
    // The work of the timer is farmed out to this method. 
    boolean isFinished() { 
    // Check how much time has passed 
    int passedTime = millis()- savedTime; 
    if (passedTime > totalTime) { 
     return true; 
    } else { 
     return false; 
    } 
    } 
} 

用戶如何在級別之間切換？是否有按鍵或鼠標按鍵會觸發下一個關卡？還是完全基於計時器？如果它是基於一個按鍵，你可以結合下面的代碼：

int level; 
Timer levelTimer; 

void setup() { 
    levelTimer = new Timer(5000); 
} 

void draw() { 
    println(levelTimer.isFinished()); 
} 

void keyPressed() { 
    switch(key) { 
    case '1': 
    level = 1; 
    levelTimer.start(); 
    break; 
    case '2': 
    level = 2; 
    levelTimer.start(); 
    break; 
    case '3': 
    level = 3; 
    levelTimer.start(); 
    break; 
    } 
} 

這樣，你的每個用戶發展到他們選擇的級別時啓動級定時器。只是一個想法。
