我想知道如何检测影片剪辑上没有按下按钮的情况，比如

if (no keys are pressed){

this.gotoAndStop("idle"); }

首先，如果您在扩展您所实现的目的时扩展您的问题，也许我可以提出更深入的解决方案......；）我无法想象为什么您需要一个无按钮按下事件。无论如何，您可以使用此代码片段。

//This belongs to no button pressed event.
    var def = 0;
    var keyListener:Object = new Object();
    keyListener.onKeyDown = function() {
       def = 1;
    };
    keyListener.onKeyUp = function() {
       def = 0;
    };
    Key.addListener(keyListener);



//First Part for the whole movie clip
    _root.onEnterFrame = function (){
        trace(def);
        if(def == 1){
        this.gotoAndStop("idle");
        }
    }

Firstly if you expand your question as you expand your purpose of what you achieve, maybe I can present a more in depth solllution ... ;) I can not imagine why you need a no buttons pressed event. Anyway you can use this code snippet.

//This belongs to no button pressed event.
    var def = 0;
    var keyListener:Object = new Object();
    keyListener.onKeyDown = function() {
       def = 1;
    };
    keyListener.onKeyUp = function() {
       def = 0;
    };
    Key.addListener(keyListener);



//First Part for the whole movie clip
    _root.onEnterFrame = function (){
        trace(def);
        if(def == 1){
        this.gotoAndStop("idle");
        }
    }
