Question

使用soundManager2，我用onclick =“mySound.play（）”创建了一个简单的锚点，但是在实际听到声音之前有一个很大的差距（差不多半秒）！这是，即使我预先加载了声音。如何才能获得更好的响应时间？

我看不到这首歌被预加载的位置。您希望在默认或createSound部分中将autoLoad设置为true（默认值应由createSound继承）。

在默认部分中，它将是soundManager.autoLoad = true;

或者在createSound方法autoLoad:true, id: 'aSound', url: 'sounds/kick.mp3'

中
