我有行星绕中心点旋转，如果按下'g'键一次，当行星经过一个平面时，hittestobject触发每个行星的单独声音。按下“e”键时，它会为每个行星播放不同的声音。此时声音在彼此之上（在顶部）播放。如何在按下g或e键时检查是否正在播放其中一种声音并将其关闭？ 我感谢任何帮助。

您不会在按键检测时删除任何一个enterframe侦听器。请注意，您有addEventListener(Event.ENTER_FRAME, hitTestmercEcc);但没有调用相应的removeEventListener(Event.ENTER_FRAME, hitTestmercEcc);。因此，两个功能同时工作，产生两组声音。在你的情况下，你最好有一个标志，告诉你想要播放什么样的声音，并从一个事件监听器调用相应的函数。像这样：
var ecc:Boolean=false; // if calling Ecc function
function onEnterFrame(e:Event):void {
if (ecc) hitTestmercEcc(e);
else hitTestmerc(e);
}
现在，只要按下这些键，就可以像这样更改ecc的值：
function displayKey(keyEvent:KeyboardEvent) {
if (keyEvent.keyCode == 71) {
ecc = false;
} else if (keyEvent.keyCode == 69) {
ecc = true;
}
}
仍然需要您的最热门功能，但请确保它们位于任何其他功能体内 NOT 。你现在他们都在function displayKey()大括号下 - 这种做法并不好。主要是因为你没有从其他地方访问嵌套函数，它可能会让你面临丑陋的问题。
