我是 Actionscript 3 和使用 Flash CS6 的新手。

-我正在尝试播放/暂停名为 countrymeadow 的 20 分钟 mp3

-countrymeadow.mp3 链接到库中的 Export for actionscript (countrymeadow)。

  • playpause mc 按钮在按钮内的第 1 帧（播放）和第 10 帧（暂停）停止。

  • AS3 在下面，但它不起作用，因为 mc 播放暂停按钮在测试时不断在“播放”和“暂停”之间切换，而且没有播放声音。

任何帮助表示赞赏，并提前非常感谢。

//set appearance of button, mode to true
playpause_mc.gotoAndStop("play");
playpause_mc.buttonMode = true;

//sound is stopped after loaded
var isPaused:Boolean = true;

//saves current position of sound
var currPos:int = 0.00;

var theSound:countrymeadow = new countrymeadow();
snd.play(); 

var soundCnl:SoundChannel = new SoundChannel();

//Listener updates after sound loads, and stops           soundtheSound.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
function onComplete(evt:Event):void {
    //Stop loaded sound
    soundCnl.stop();
}


// movie clip button control
playpause_mc.addEventListener(MouseEvent.CLICK, clickHandler);
function clickHandler(event:MouseEvent):void {

    if(isPaused){
        //change state to playing, and play sound from position
        isPaused = false;
        soundCnl = theSound.play(currPos); 

        //reverse the appearance of the button
        playpause_mc.gotoAndStop("pause")

        //if sound completes while playing, run function
        soundCnl.addEventListener(Event.SOUND_COMPLETE, soundCompleteHandler);

    }else{
        //it's playing, so save position and pause sound
        currPos = soundCnl.position;
        isPaused = true;
        soundCnl.stop();

        //change the appearance of the buttons
        playpause_mc.gotoAndStop("play")
    }
}

SoundChannelposition是一个Number变量。那是范围 0 到 1。但是你设置了int变量。int不是浮点类型。因为您已明确声明为int类型。即使当你变成浮点初始化，转换为int类型。

在此处输入图像描述

你应该遵循这个。并且您的 clickHandler 函数进行了一些更正。

var currPos:Number = 0.0;

soundCnl.addEventListener(Event.SOUND_COMPLETE, soundCompleteHandler);
function clickHandler(event:MouseEvent):void {

    if(isPaused){
        //change state to playing, and play sound from position
        isPaused = false;
        soundCnl.play(currPos); 

        //reverse the appearance of the button
        playpause_mc.gotoAndStop("pause")

    }else{
        //it's playing, so save position and pause sound
        currPos = soundCnl.position;
        isPaused = true;
        soundCnl.stop();

        //change the appearance of the buttons
        playpause_mc.gotoAndStop("play")
    }
}

测试代码：

var n:int = 0.0;

n = 0.5;

trace("n: " + n); //you may expected 0.5, but return 0.
