Question

我是AS3的新手，现在我正试图按下一个按钮（用形状工具在fla中制作）按下汽车指示灯时闪烁3次。我已将它转换为符号并且当前正在尝试编写类本身（我不确定我是否要编写符号类或直接连接到fla的主类）。现在我有3个类2个三角形（Rblinker和Lblinker）和“MAIN”。

最大的问题是，我似乎无法通过鼠标点击按钮闪烁，任何身体都可以帮助吗？谢谢

现在我的“Rblinker”代码看起来像这样。

package  {

import flash.display.MovieClip;
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.events.MouseEvent

public class Rblinker extends MovieClip {

    public var timer:Timer =  new Timer(1000,3);
    public var blink:Boolean = true;
    timer.start();


    public function Rblinker() {
        this.addEventListener(MouseEvent.click, clickaction);


        function clickaction(e:MouseEvent):void{
            timer.addEventListener(TimerEvent.TIMER, timerAction);
            this.alpha = 1;
    }


    function timerAction(e:TimerEvent):void
        {
            if (!blink){
                this.alpha = 1;
                } 
            else{
                this.alpha = 0;
                }

        blink = !blink;
        }
    }
}

两个闪光灯都有相同的代码。也想只使用AC3语言

试试这个：

public class Rblinker extends MovieClip {

    public var timer:Timer =  new Timer(1000,3);//tick every second, 3 times total


    public function Rblinker() {
        this.addEventListener(MouseEvent.CLICK, clickaction);

        //add listeners in the constructor
        timer.addEventListener(TimerEvent.TIMER, timerAction);
        timer.addEventListener(TimerEvent.TIMER_COMPLETE, timerComplete);
    }

    function clickaction(e:Event):void {
        //on the click, hide it to start, then start the timer
        this.visible = false;
        timer.reset(); //reset first so it always goes 3 times even if it's clicked again before finishing
        timer.start();
    }


    function timerAction(e:TimerEvent):void
    {
       //toggle the visibility of this sprite every timer tick
       this.visible = !this.visible;

       //or, if you want to keep using alpha (so the button can still be clicked when not visible)
       this.alpha = alpha > 0 ? 0 : 1;   //this is an inline if statment
    }

    function timerComplete(e:TimerEvent):void {
        //now that the timer is totally done, make sure the item is visible again
        this.visible = true;
    }
}

如何在鼠标单击时使按钮闪烁/闪烁？
