动作脚本 3 计数器/按钮颜色更改

Question

我是 Action Script 的新手，需要帮助。

基本上，我有 50 个按钮，每个按钮的形状都是其对应的美国州的形状。我的意图是这样的，我将有一个只有一个正确答案的问题显示（例如，哪个状态是阳光状态？）然后目标是点击正确的状态。

我的问题是保持分数，我想我可以通过这两种方式进行，但我在这两种方式中都在苦苦挣扎。 第一种方法是计数器，如果你点击正确的状态给计数器加一个点，如果你点击不正确的状态不加一个点，但错误或正确，两次点击都会带你到下一个问题。这个问题是创建一个计数器，我尝试了很多东西，但似乎无法让它工作。

另一个选项是单击正确的状态会将该状态的颜色更改为绿色，单击错误的状态会将正确状态的颜色更改为红色，两次单击仍会将您带到下一个问题。我也尝试过这种方法，但似乎无法弄清楚如何更改按钮的颜色。除了我声明的 50 个状态按钮（即 virginiabutton.addEventListener(MouseEvent.CLICK, virginiabuttonclick);

编辑

所以我拿出了柜台，我真的不再需要它了，因为颜色几乎可以工作了。所以我遇到的问题是任何问题，如果你点击正确的状态，把正确的状态变成绿色，然后转到下一个问题。如果您单击错误的状态，请将正确的状态变为红色，然后转到下一个问题。除了“错误点击”功能外，这段代码完全可以做到这一点。当我单击不正确的状态时，它只会将不正确的状态（在本例中为 CA）变为红色，而不是 VA 变为红色。我认为代码中的问题在于它说“e.currentTarget”的else函数。我希望它改为将当前正确状态更改为红色而不是当前目标。

var currentCorrectState:DisplayObject; 

var correctColor:ColorTransform = new ColorTransform();
correctColor.color = 0x009900; //green

var wrongColor:ColorTransform = new ColorTransform();
wrongColor.color = 0x990000; //red

virginiabutton.addEventListener(MouseEvent.CLICK, buttonClick);
californiabutton.addEventListener(MouseEvent.CLICK, buttonClick);
// have just these two in for now just so i have a correct state(va) and incorrect state(ca)

currentCorrectState = virginiabutton
//va is correct state for this question

function buttonClick(e:Event):void {

    if(e.currentTarget == currentCorrectState){
       DisplayObject(e.currentTarget).transform.colorTransform = correctColor;
       gotoAndStop(3);
        //this code works, it transforms VA to green which is what I want. It also goes to the next question.

    }else{
       DisplayObject(e.currentTarget).transform.colorTransform = wrongColor;
        gotoAndStop(3);
        //this code doesn't work, it only transforms the currenTarget state(in this case CA) to red. it also goes to the next question which works. 
    }

}

以下是您可以尝试的示例：

var ctr:int = 0; //counter to hold the amount of correct gueses

var currentCorrectState:DisplayObject; //var for holding the current state that is correct.

var correctColor:ColorTransform = new ColorTransform();
correctColor.color = 0x009900; //green

var wrongColor:ColorTransform = new ColorTransform();
wrongColor.color = 0x990000; //red

virginiabutton.addEventListener(MouseEvent.CLICK, buttonClick);
//add the rest of click listeners, best to do it in a loop so it's not so tedious

//generic click handler for all buttons
function buttonClick(e:Event):void {
    //turn the correct state the correct color:
    currentCorrectState.transform.colorTransform = correctColor;

    //e.currentTarget is the button that was clicked
    if(e.currentTarget == currentCorrectState){
       ctr++; //increment the correct counter

       //answer was correct, so make the correct state green
       currentCorrectState.transform.colorTransform = correctColor;

       //do anything else you want to do if they answered correct
    }else{
       //answer was incorrect, make the correct state red
       currentCorrectState.transform.colorTransform = wrongColor;
       //do anything else you want to do when they answer incorrect
    }

    //if you have a score text field update it
    score.text = "Your Score: " + ctr;

    //go to the next question (however you do that)
    nextQuestion();

}

function nextQuestion():void {
    //ask your question, however you do that

    //if there was a previous question, reset the last states color
    if(currentCorrectState) currentCorrectState.transform.colorTransform = new ColorTransform();

    //set the correct answer for this new question
    currentCorrectState = virginiabutton; 
}
