所以我试图从我的身体里射出多颗子弹，这一切都有效，除了我有一个奇怪的问题，即只有一颗子弹出现并更新为新子弹设置位置。我有一个可以移动的玩家，它应该可以射击，我通过移动玩家和射击来测试这段代码。我一步一步地创建它。

跟踪 bulletContainer 的结果是正确的，因为它告诉我电影剪辑正在添加到舞台；我只知道这归结为某种我忘记的逻辑。

这是我的代码（子弹本身就是一个类）

更新* 这段代码中的所有内容都可以正常工作，除了我之前说过的一些代码似乎是重复的，因为我采用了不同的方法。

好吧......如果我可以这样说，这段代码看起来很错误。要么代码中缺少某些东西，要么此代码永远不会让子弹飞起来。

首先，您可以直接设置新子弹的 x 和 y（将“从玩家身体定位此子弹”之后的所有内容替换为）：

tmpBulletId.x = Object(root).localSurvivor.x;
tmpBulletId.y = Object(root).localSurvivor.y;

也许这已经有所帮助，但是您的代码应该已经这样做了。

但要让这些子弹飞向任何方向，还需要添加一个事件监听器，如下所示：

tmpBulletId.addEventListener(Event.ENTER_FRAME, moveBullet);

function moveBullet(e:Event) {
    var movedBullet:MovieClip = MovieClip(e.currentTarget);
    if (movedBullet.x < 0 || movedBullet.x > movedBullet.stage.width || 
        movedBullet.y < 0 || movedBullet.y > movedBullet.stage.height) {

        // remove move listener, because the bullet moved out of stage
        movedBullet.removeEventListener(Event.ENTER_FRAME);
    }
    // remove the comment (the //) from the line that you need
    MovieClip(e.currentTarget).x += 1; // move right
    // MovieClip(e.currentTarget).y -= 1; // move up
    // MovieClip(e.currentTarget).x -= 1; // move left
    // MovieClip(e.currentTarget).y += 1; // move down
}

这个例子让你的子弹飞到右边。如果您需要它飞向另一个方向，只需用“向右移动”注释注释掉该行并取消注释其他行之一。

这当然是一个非常简单的示例，但它应该可以帮助您入门。

我希望这会有所帮助，并且我的答案不是问题的错误答案。

据我所知，您只能将一个 MovieClip 对象的副本添加到特定的孩子。最好的方法是使用 ByteArray 作为剪辑源并实例化新的 MovieClip 并将 ByteArray 作为源传递。它与子/父关系有关，因为 DisplayObject 只能有一个父对象（以及一种将对象从场景中分离的方法）。

好吧，我最终第三次从头开始编写整个代码并遇到了类似的问题，只是为了参考其他任何遇到随机问题的人，因为我发现这个问题很可能是某个地方的转换错误不一定违反任何编译规则。只是我在调用一个movieclip，而不是它自己的类。
