按鈕文本出現的代價是知道哪個答案被點擊

Question

代碼運行良好，但我遇到的問題是，假設要進入我的答案按鈕的文本框在按鈕本身後面...但是，如果我更改了兩行代碼，答案驗證代碼不會提取哪個答案被點擊（它返回未定義）。這真令人氣憤！

尋找「// INSERT HERE」行。如果我接受該行，「var answerField：TextField = createText（answer，answerFormat，answerSprite，0,0,450）;」並把它放在那裏，它會返回正確的答案（不返回undefined），但我不能再看到文本。我也包含了createText函數。

想法？

private function askQuestion() 
    { 
     trace("asking question..."); 

     // prepare new question sprite 
     qBox = new QuestionBox(); 
     questionSprite = new Sprite(); 
     gameSprite.addChild(qBox); 
     gameSprite.addChild(questionSprite); 
     qBox.x = 240; 
     qBox.y = 45; 

     // create text field for question 
     var question:String = dataXML.item[questionNum].question; 
     questionField = createText(question,questionFormat,questionSprite,120,30,250); 

     // create sprite for answers, get correct answer and shuffle all 
     correctAnswer = dataXML.item[questionNum].answers.answer[0]; 
     trace("----" + correctAnswer + "----"); 
     answers = shuffleAnswers(dataXML.item[questionNum].answers); 

     // put each answer into a new sprite with a circle icon 
     answerSprites = new Sprite(); 

     for (var i:int=0; i<answers.length; i++) 
     { 
      trace("generating answers..."); 
      switch (i) 
      { 
       case 0 : 
        column = 135; 
        row = 150; 
        break; 
       case 1 : 
        column = 135; 
        row = 260; 
        break; 
       case 2 : 
        column = 340; 
        row = 150; 
        break; 
       case 3 : 
        column = 340; 
        row = 260; 
        break; 
      } 
      var answer:String = answers[i]; 
      var answerSprite:Sprite = new Sprite(); 
      //INSERT HERE 
      var button:Button = new Button(); 

      answerSprite.x = column; 
      answerSprite.y = row; 

      // make it a button; 
      answerSprite.addChild(button); 
      var answerField:TextField = createText(answer,answerFormat,answerSprite,0,0,450); 
      answerSprite.addEventListener(MouseEvent.CLICK,clickAnswer); 
      answerSprite.buttonMode = true; 
      answerSprites.addChild(answerSprite); 
     } 
     trace("answers generated!"); 
     questionSprite.addChild(answerSprites); 
     trace("question asked!"); 
     trace(":::awaiting user input:::"); 
    } 

createText功能：

public function createText(text:String, tf:TextFormat, sprite:Sprite, x,y: Number, width:Number):TextField 
    { 
     var tField:TextField = new TextField(); 
     tField.x = x; 
     tField.y = y; 
     tField.width = width; 
     tField.wordWrap = true; 
     tField.multiline = true; 
     tField.selectable = false; 
     tField.defaultTextFormat = tf; 
     tField.text = text; 
     sprite.addChild(tField); 
     return tField; 
    } 

Answer 1

你插入answerSprite.addChild(button);後，你作出這樣的方法調用。

試着把那裏的插入這裏，你會沒事的。

即

 var answerSprite:Sprite = new Sprite(); 
     var button:Button = new Button(); 
     // make it a button; 
     answerSprite.addChild(button); 
     var answerField:TextField = createText(answer,answerFormat,answerSprite,0,0,450); 
      answerSprite.x = column; 
      answerSprite.y = row; 

Answer 2

我需要給該按鈕的名稱，然後使用該名稱來標識的按鈕。
