按钮文本的显示是以不知道单击了哪个答案为代价的

Question

代码运行良好，但我遇到的问题是，应该进入答案按钮的文本框位于按钮本身后面......但是，如果我更改两行代码，答案验证代码不获取单击的答案（它返回未定义）。这太令人气愤了！

查找“//INSERT HERE”行。如果我采取这一行，“var answerField：TextField = createText（answer，answerFormat，answerSprite，0,0,450）;”并将其放在那里，它返回正确的答案（不返回未定义），但我再也看不到文本了。我还包含了 createText 函数。

有想法吗？

    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:::");
    }

创建文本函数：

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

您将在调用该方法后插入 answerSprite.addChild(button); 。

尝试将其放在 INSERT HERE 上方，就可以了。

IE

        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

我需要为按钮命名，然后使用该名称来识别按钮。
