AS3: Как я могу ответить на ответ зеленым или красным цветом, если ответ был прав или нет в викторине?

Question

Я получил этот код у своего наставника, и сама викторина работает; вы можете выбрать ответы и отслеживать, что вы это сделали, но не распознаете, правильно ли вы ответили или нет.

Я хочу, чтобы он выделял зеленый или красный цвет в зависимости от того, был ли нажат правильный ответ; но я не знаю, какой код правильный, поскольку я все еще новичок в Action script. Правильный ответ указан в XML, я просто должен ссылаться на код, который, как я думаю. Любая помощь?

Вот код:

package { 

    import flash.display.MovieClip; 
    import flash.text.TextField; 
    import flash.text.TextFormat; 
    import flash.text.TextFieldAutoSize; 
    import flash.net.URLLoader; 
    import flash.net.URLRequest; 
    import flash.events.Event; 
    import flash.events.MouseEvent; 
    import TabAnswer; 
    import IconNext; 

    public class Quiz extends MovieClip { 

     private var tf:TextFormat = new TextFormat ; 
     private var question:TextField = new TextField ; 
     private var answer:TabAnswer; 
     private var answers:Array = new Array ; 
     private var quiz:XML; 
     private var next:IconNext = new IconNext ; 
     private var currentQuestion:int = 0; 

     public function Quiz() { 
      // constructor code 
      var xmlLoader:URLLoader = new URLLoader ; 
      xmlLoader.addEventListener(Event.COMPLETE,xmlLoaded); 
      xmlLoader.load(new URLRequest("quiz.xml")); 
     } 

     private function xmlLoaded(e:Event):void { 
      // make an XML instance using XML data passed to this function 
      quiz = new XML(e.target.data); 
      trace(quiz); 
      //set some text formatting 
      tf.size = 20; 
      tf.color = 0x000000; 
      tf.font = "Tw Cen MT Condensed"; 
      //create a textfield for question information 
      addChild(question); 
      question.setTextFormat(tf); 
      question.multiline = true; 
      question.width = question.textWidth; 
      question.autoSize = TextFieldAutoSize.LEFT; 
      question.defaultTextFormat = tf; 
      question.text = quiz.question[currentQuestion].description; 
      for (var a = 0; a < 4; a++) 
      { 
       var answer = new TabAnswer ; 
       answers.push(answer); 
       addChild(answers[a]); 
       answers[a].x = question.x; 
       answers[a].y = question.y + question.height + answer.height + ((a * answer.height) * 1.5); 
       answers[a].answer.text = quiz.question[currentQuestion].answers.answer[a]; 
       answers[a].addEventListener(MouseEvent.MOUSE_DOWN,answerSelected); 
      } 
      addChild(next); 
      next.x = stage.stageWidth - next.width * 1.3; 
      next.y = stage.stageHeight - next.height * 2.3; 
      next.addEventListener(MouseEvent.MOUSE_DOWN,nextQuestion); 
     } 

     private function answerSelected(e:MouseEvent):void { 
      trace(e.currentTarget.answer.text); 
      //check to see if the answer that has been pressed, matches the 
      //correctAnswer node in the quiz xml question 
     } 

     private function nextQuestion(e:MouseEvent):void { 
      currentQuestion++; 
      getQuestion(currentQuestion); 
     } 

     private function getQuestion(questionToGet:int):void { 
      question.text = quiz.question[questionToGet].description; 
      for (var a = 0; a < 4; a++) 
      { 
       answers[a].answer.text = quiz.question[questionToGet].answers.answer[a]; 
      } 
     } 
    } 
} 

Вот XML поэтому он будет делать это немного больше смысла, как это возможно, работает ?:

Answer 1

private function answerSelected (e:MouseEvent):void 
{ 
    trace (e.currentTarget.answer.text); 
    //check to see if the answer that has been pressed, matches the 
    //correctAnswer node in the quiz xml question 
    if (e.currentTarget.answer.text == quiz.question.correctAnswer.text) 
     trace("correct answer is:",quiz.question.correctAnswer.text,"answer picked was:",e.currentTarget.answer.text); 
     // change text color, or whatever. 
    } 
} 

Попробуйте это. Дайте мне знать, что это такое, если он не работает.
