Event.SOUND_COMPLETE在AS3

Question

我已經看到了很多foruns的嘗試使一個聲音運行其他

在LoaderS1後，這種情況下LoaderS2後...

有人可以幫助，這是我的代碼。 ..我不知道該怎麼做...：S

這是一個程序來顯示2圖像，用戶需要選擇正確的一個後聽聲音。

這個想法是在我加載2個圖像後，我將運行LoaderS1將運行，並且HL_Left將使矩形環繞圖片以突出圖像，並且當完成時他將再現第二個soun LoaderS2。

這就是我想做的事情...需要幫助和快速...

的Sound類不會調度Event.SOUND_COMPLETE事件。您正在尋找的是SoundChannel班（http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/SoundChannel.html）。

的Sound類的play方法返回一個SoundChannel實例，所以你想做的事是：

var s1Channel:SoundChannel = Loader_S1.play(); 
s1Channel.addEventListener(Event.SOUND_COMPLETE, audioComplete);
