as3 导航 - 转到和播放脚本无法始终如一地工作

Question

我想我在某处的逻辑上犯了一个错误，但找不到它，我有一个影片剪辑，其中包含 4 个进一步的动画电影剪辑，每个剪辑在特定帧处都有 stop（） 动作，还有 2 个按钮，一个用于向左移动，另一个用于向右移动，如果用户单击说右、右、右、 第一次向右，向左，向左，向左，但随后事情停止了正确评估。

正在对变量使用开关大小写语句来挑选要进行动画处理的 mc，使用 If Else 语句会更好吗？这是我的代码，因为很明显，动作脚本不是我的强项！

我修复了它，基本上我在gotoAndPlay中定位的帧包含stop（）语句，一旦我针对后续帧，即

而不是：

switch (boxAnimPlay) {
    case 3:
        mc1.box4.gotoAndPlay(17);
        mc1.box3.gotoAndPlay(31);
    break;
    case 2:
        mc1.box2.gotoAndPlay(31);
        mc1.box3.gotoAndPlay(46);
    break;
    case 1:
        mc1.box1.gotoAndPlay(17);
        mc1.box2.gotoAndPlay(46);
    break;
    }

我用了这个：

switch (boxAnimPlay) {
    case 3:
        mc1.box4.gotoAndPlay(17);
        mc1.box3.gotoAndPlay(32); // no stop on subsequent frame
    break;
    case 2:
        mc1.box2.gotoAndPlay(32); // no stop on subsequent frame
        mc1.box3.gotoAndPlay(47); // no stop on subsequent frame
    break;
    case 1:
        mc1.box1.gotoAndPlay(17);
        mc1.box2.gotoAndPlay(47); // no stop on subsequent frame
    break;
    }
