我正在創建一個處於測驗樣式的FlashCS4應用程序。問題存儲在一個單獨的文本文件中,並通過as3調用到程序中。這一切都很好,但我想知道如何隨機化這些數據,但要確保同一個問題不會被拉兩次。隨機抽取as3中調用變量的順序
例如,當我導航到問題頁面時,我可以顯示問題的每個部分(回答a,b,c,d +問題本身),然後可以進行10次。
我想要做的是使這10個問題從我在文本文件中的(27?)問題中隨機生成。
import flash.geom.Transform;
import flash.geom.ColorTransform;
import fl.motion.Color;
var glowFilter:GlowFilter = new GlowFilter(0x000000, 1, 2, 2, 10, 3)
var questionNumber:int = 0;
var totalCorrect:int = 0;
var selectedAnswer:String;
var checkAnswer:String;
var correctAnswer:String;
var questionCount:int = 0;
var numberOfQuestions:int = 10;
txt_loggedin_Question.text = (userName);
//Displays the Question Number which is called in from XML
txt_QuestionNumber.text = ("Question #"+questions[questionNumber].ref +" of"+numberOfQuestions);
function CheckAnswer() {
if (selectedAnswer == correctAnswer){
totalCorrect = totalCorrect + 1;
trace("Correct");
}else{
totalCorrect = totalCorrect;
trace("incorrect");
}
questionNumber = questionNumber + 1;
questionCount = questionCount + 1;
//Random questions set up new variable questioncount
if (questionCount == numberOfQuestions){
trace("we are at 10");
gotoAndStop (1, "Result");
//STOP RUN NEXT SCENE
}else{
setUpQuestions()
}
有代碼缺少一個公平一點,但我希望這涵蓋了要領,該文件被稱爲一個單獨的頁面上,
var questions:Array = [ ];
var request:URLRequest = new URLRequest("1.txt");
var loader:URLLoader = new URLLoader(request);
loader.addEventListener(Event.COMPLETE, completeHandler);
function completeHandler(event:Event):void
{
// loader data - the questions.txt file
var data:String = event.target.data;
// split data by newline for each question
var lines:Array = data.split("\n");
// for every line
for each (var line:String in lines)
{
// split line by "||" delimiter
var question:Array = line.split("||");
// add the question to the questions array:
questions.push({ref: question[0],
question: question[1],
answerA: question[2],
answerB: question[3],
answerC: question[4],
answerD: question[5],
answerE: question[6],
correct: question[7],
answer: question[8],
type: question[9],
file: question[10]});
}
}
所有這一切工作,但唯一我掙扎的是每次在場景加載時從文本文件中隨機生成問題。很抱歉,這個冗長的問題。
感謝您的閱讀。
謝謝你,整形外科醫生。 – user2221709 2013-04-11 11:55:10

對不起,我只是解決了一些設計問題,一旦我實現了它,我會點擊勾號。如果沒問題,再次感謝你。 – user2221709 2013-04-12 16:42:15
