Question

如何在不获得相同值的情况下随机化这组数组？我不知道我做得对。如何在变化时识别价值？

function Start () 
    {
    if(MasterVar.quiz<10)
    {
        var englishLecture = [
        ["Word that tells us about an action","Verb","Noun","Pronoun","a","0"],
        ["Name of person, place or things","Verb","Noun","Cute","b","0"],
        ["Select the noun","Swim","Shout","Joe","c","0"],
        ["There __ a cat","is","was","can","a","0"],
        ["You __ go home now","can","open","was","a","0"],
        ["She ___ her breakfast","ate","play","sleep","a","0"],
        ["Select the verb","John","is","table","b","0"],    
        ["We ___ planning to go to the movies tonight","were","could","can","b","0"],
        ["What ____ that noise?","Were","Was","Can","b","0"],
        ["What ___ your name?","are","can","is","c","0"]
        ];
        index = Random.Range(0,englishLecture.length);
        while(englishLecture[index][5] == "1")
         {
             index = Random.Range(0,englishLecture.length);
         }
        englishLecture[index][5] == "1";

        TextGUI =  GameObject.FindGameObjectWithTag("Question");
        TextGUI.GetComponent(GUIText).text = englishLecture[index][0];
        sel1 = englishLecture[index][1];
        sel2 = englishLecture[index][2];
        sel3 = englishLecture[index][3];
        rightAns = englishLecture[index][4];
    }
    else if(MasterVar.quiz>=10)
    {
            Application.LoadLevel("Score");
    }
}

我假设“0”/“1”值用于存储先前是否询问过问题，并且while循环用于选择新的随机问题，直到找到未答复的问题。

您已经将值从“0”更改为“1”，但主要问题是，一旦设置为“1”，您再也不会再读它了。

如果您希望应用程序记住问题被标记为已解答（“1”），则需要将该数据写入本地文件，并在应用程序启动时从该文件中读取数据。您需要了解文件I / O和序列化才能做到这一点： http://msdn.microsoft.com/en-us/library/vstudio/ms172873.aspx

如果您在询问第一个随机问题后只需要提出另一个问题，那么在第一个问题被标记为已回答后，您需要重复询问问题的代码。您可以通过使用while循环，事件或将问题代码封装到函数中来实现。这都是关于结构的！

例如，你想要离开这个：

index = Random.Range(0,englishLecture.length); 

while(englishLecture[index][5] == "1") { 
    index = Random.Range(0,englishLecture.length); 
} 

englishLecture[index][5] == "1";

TextGUI =  GameObject.FindGameObjectWithTag("Question");
TextGUI.GetComponent(GUIText).text = englishLecture[index][0];
sel1 = englishLecture[index][1];
sel2 = englishLecture[index][2];
sel3 = englishLecture[index][3];
rightAns = englishLecture[index][4];

//Add code to manage user interaction here

......对此：

for (var i = 0; i < 5; i++) {  // This will ask 5 questions
    AskRandomQuestion();
}

function AskRandomQuestion() {

    index = Random.Range(0,englishLecture.length); 

    while(englishLecture[index][5] == "1") { 
        index = Random.Range(0,englishLecture.length); 
    } 

    englishLecture[index][5] == "1";

    TextGUI =  GameObject.FindGameObjectWithTag("Question");
    TextGUI.GetComponent(GUIText).text = englishLecture[index][0];
    sel1 = englishLecture[index][1];
    sel2 = englishLecture[index][2];
    sel3 = englishLecture[index][3];
    rightAns = englishLecture[index][4];

    //Add code to manage user interaction here
}

另外，请注意，当所有问题都被标记为已回答时，while子句将无限循环，永远不会找到未回答的问题，并且应用程序将崩溃。

更好的设计是将所有未回答的问题提取到一个新数组中（创建一个仅包含未回答问题的数组）。如果该数组不为空，您可以在其中选择一个随机问题。否则，您知道所有问题都已得到解答。

类似的东西：

function AskRandomQuestion() {

    unasweredQuestions = new Array();

    for (var i = 0; i < englishLecture.length; i++) {
        if (englishLecture[i][5] == "0") {
            unansweredQuestions.push(englishLecture[i]);
        }
    }

    if (unansweredQuestions.length > 0) {
        selectedQuestion = unansweredQuestions[Random.Range(0,unansweredQuestions.length)]
        selectedQuestion[5] == "1";

        TextGUI =  GameObject.FindGameObjectWithTag("Question");
        TextGUI.GetComponent(GUIText).text = selectedQuestion[0];
        sel1 = selectedQuestion[1];
        sel2 = selectedQuestion[2];
        sel3 = selectedQuestion[3];
        rightAns = selectedQuestion[4];

        // Add code to manage user interaction here
    } else {
        // All questions were answered, quit or reset
    }

}

这是所有未经测试的代码，可以从一些优化中受益，但它应该可以帮助您入门。
