AS3自上而下查看游戏声音延迟在新级别负载上延迟延迟

Question

对于上课，我必须制作as3自上而下的观看游戏。

在level1中似乎一切正常但在level2上有一个声音延迟。当角色与level2中的手发生碰撞并且声音对象被调用时，声音不会立即播放，它会延迟直到碰撞不成立，并且只有在角色没有从发生碰撞的地方移动时才会播放。

目前，角色在第1级运行，同时正确地在与其.cc_mc对撞机对象和手的hc_mc对撞机对象发生碰撞时进行声音播放......但是在level2角色上碰撞新手并且声音直到level2才会播放。 hand.grabbing_mc消失了。定时手首先摇摆一个参数进入摇摆实例，然后进入标记为“grabbing_mc”的抓取实例。 hc_mc对撞机对象在grabbing_mc中。奇怪的是，镰刀尖叫声在整个游戏中运行良好，没有滞后。

下面我有一个我的screengame类的剥离版本，可以完成游戏的大部分工作;大部分只是声音相关的部分。有谁知道如何在碰撞后消除2级的延迟？提前谢谢。
