Flash AS3 -如何在播放时将每个帧随机化

Question

我在框架2-11中有一些测试级别1，框架12是测试的结果，在框架13-22中有测试2级，在框架23中有结果。

我想把2-11之间的测试随机化，在13-22帧中随机化测试，

示例:

1. 第一项测验是第三组。
2. 第二项测验是第六组。
3. 第三项测验是第二组。
4. (.)
5. (N)第.(尚未显示的最后一帧)

我在框架1中使用这个代码：

stop();
autom.play();
soal = 1;
var pic:Number=11;
var randomFrame:Number = Math.ceil(Math.random()*pic);
trace(randomFrame);
gotoAndStop(randomFrame);
nextFrame();

但是闪光灯只是第一次随机化

我想知道是否有一种方法可以使闪存像我在示例？中所希望的那样运行良好？？

in frame 2 till 11 are a same code like this :

kuncinya("a") // the correct answer of a question;  

Answer 1

你需要跟踪你去过的帧，这样你就不会重复，这样你就知道什么时候完成测试了。

最容易做到这一点的方法可能是有一个问题框架数组，然后在完成问题时从该数组中删除问题框架。

类似于这样的东西：

框架1代码：

//a var to hold the current quiz (an array/collection of frames)
var curQuiz:Array;

//a var to hold the ending frame of the current quiz
var curQuizEndFrame:int;

 //the frame number or labels that are questions for this quiz
var quiz1:Array = [2,3,4,5,6,7,8,9,10,11];
var quiz2:Array = [13,14,15,16]; //etc

//create a function to start a quiz with two parameters - the quiz array to start, and the frame to goto once all the questions have been asked.
function startQuiz(quiz:Array, endFrame:int):void {
    curQuizEndFrame = endFrame;
    curQuiz = quiz.concat(); //this copies the passed in quiz array (so you don't modify the original)

    //randomize the question order
    curQuiz.sort(randomizeArray);

    //now call nextQuestion (created below) to go to the first question
    nextQuestion(); 
}

//create a function to show the next question. Call this whenever the user answers a question - the e parameter is just there in case you want to call this function from an event handler
function nextQuestion(e:Event = null):void {
    //check if there is a current quiz, and if there are still questions left in it
    if(curQuiz && curQuiz.length > 0){
        //goto the next question in the quiz
        gotoAndStop(curQuiz.pop()); //pop removes the last element from the array and returns its value
    }else{
        if(curQuiz){
            //if we get here, it means the quiz exists but doesn't have any questions left, so go to the end frame
            gotoAndStop(curQuizEndFrame); //quiz is finished
        }else{
            //quiz hasn't started yet, do something like tell the user to start the quiz
        }
    }
}

//a randomize sort function for arrays
function randomizeArray(a:*,b:*):int {
    return(Math.random() > .5) ? 1 : -1;
}

然后，每当您完成一个问题时，调用nextQuestion(); --这很可能是在next按钮上单击每个问题框架上的处理程序。

nextBtn.addEventListener(MouseEvent.CLICK, nextQuestion, false, 0, true);

每当您想要开始一个新的测试时，调用startQuiz并传入测试数组和结束帧。

例如：

startQuiz(quiz1, 12);
