Flash AS3 - 如何在播放时随机化每一帧

Question

我在第 2-11 帧中有一些第 1 级测验，第 12 帧是测验的结果，第 13-22 帧中的第 2 级测验结果在第 23 帧中..

我想在 2-11 之间随机化一个测验，在 13-22 帧中随机化一个测验，

示例：

第一个测验是第 3 帧
第二个测验是第 6 帧
第三个测验是第 2 帧
(... ...)
第(n) ... ... ...（最后一帧尚未显示）

我在第 1 帧中使用此代码：

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

但闪光灯只是第一次随机化

我想知道是否有办法使闪光灯运行像我在示例中想要的那样？？？

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

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

Answer 1

您需要跟踪您去过的帧，这样您就不会重复，这样您就知道测验何时完成。

执行此操作的最简单方法可能是拥有一个问题框架数组，然后在您完成问题时从该数组中删除问题框架。

大致如下：

第1帧代码：

//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(); 这可能会出现在每个问题框架的下一个按钮单击处理程序上。

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

每当您想开始新的测验时，调用 startQuiz 并传入测验数组和结束帧。

例如：

startQuiz(quiz1, 12);
