如何将MovieClip实例添加到多个影片剪辑并迭代MovieClip父级的子项？

Question

var mainmc:MovieClip;
var mc1:MovieClip;
var mc2:MovieClip;
var mc3:MovieClip;
var lastmc:MovieClip;

mainmc.addChild(mc1);
mainmc.addChild(mc2);
mainmc.addChild(mc3);

mc1.addChild(lastmc);
mc2.addChild(lastmc);
mc3.addChild(lastmc);

for(var i=1; i<4; i++){ 
  mainmc.?????.lastmc.visible=false;
}

我需要在问题上写下什么？

Answer 1

无。您不能同时向多个父母添加相同的MovieClip lastmc。从您的代码中，lastmc将只在mc3

中

如果您想迭代mainmc的孩子：

var i: uint, len: uint = mainmc.numChildren, movie:MovieClip;

for(i; i < len; ++i){
    movie = mainmc.getChildAt(i) as MovieClip;
    if(movie != null && movie.numChildren > 0){
        movie.getChildAt(0).visible = false;
    }
}
