function roll(){
randomNumber = Math.ceil(Math.random() * range);
randomNumber2 = Math.ceil(Math.random() * range);
randomNumber3 = Math.ceil(Math.random() * range);
dice1_mc.gotoAndStop(randomNumber);

dice3_mc.gotoAndStop(randomNumber3);
num1 = int(randomNumber);
num2 = int(randomNumber2);
num3 = int(randomNumber3);
trace(num1);
trace(num2);
trace(num3)
}

      function AddCheck(e:MouseEvent):void {
       ans = num1+num2+num3;
       if (displayText.text == String(ans)){
        //score++;

    function RandomizeOperation(){
    var oprange:uint = 2;
    opsymbol = Math.ceil(Math.random() * oprange);
    //opsymbol = 2;
        //trace(opsymbol);

      if(opsymbol == 1){
    dice2_mc.visible= true;
    trace(opsymbol + " addition");
    enterAns_btn.addEventListener(MouseEvent.CLICK, AddCheck);
    roll();
        }
        if(opsymbol == 2){
    dice2_mc.visible= true;
    trace(opsymbol + " subtraction");
    enterAns_btn.addEventListener(MouseEvent.CLICK, SubCheck);
    roll();
        }

            }

每次问题发生变化时，操作都会延续。我不知道什么是错的。

示例第一个问题是1 + 2 + 3（这是6），下一个问题是减法（3-3-1-正确答案假设为-1）但它添加了。我无法弄清楚什么是错的

Answer 1

这里没有任何东西。您只是不将鼠标的eventListener从一种类型移到另一种类型，而是添加已经存在的MouseEvent。两条痕迹同时是一个很大的线索：

您需要{ }内的if (opsymbol == 2)：

//will remove ANY existing current listeners to some function
enterAns_btn.removeEventListener(event.type, arguments.callee);
//adds a new listener to some function for this new Check type
enterAns_btn.addEventListener(MouseEvent.CLICK, SubCheck);

为什么会这样：

if (opsymbol == 1)
{ 
    //CHECK ONE: enterAns_btn listens for ADD
    enterAns_btn.addEventListener(MouseEvent.CLICK, AddCheck); 
}

if (opsymbol == 2)
{ 
    //CHECK TWO: enterAns_btn listens for SUBTRACT
    enterAns_btn.addEventListener(MouseEvent.CLICK, SubCheck); 
}

因为CHECK TWO发生在CHECK ONE之后，此时你现在告诉Flash enterAns_btn 必须在鼠标点击时实际执行两项功能..基本上它听到了这个命令：

enterAns_btn.addEventListener(MouseEvent.CLICK, AddCheck); //added by check one
enterAns_btn.addEventListener(MouseEvent.CLICK, SubCheck); //added by check two

这就是为什么你一次得到两条痕迹的结果..一个用于添加给你7，另一个用于减去给-1。希望它有帮助。

操作继续下一个随机
