第一个是制作一排5条船，从上到下定位它们。然后添加一个事件让它们向下移动。 但是每当我尝试制造一个新的5艘新船时......他们在上一排的最后一艘船后定位。我确实想到了一种方法来解决这个问题，等待第一排船超越舞台然后将它们从舞台中移除并从阵列中拼接但是......当我提高产卵速度时（当我在舞台上有2行，有5艘船或更多）时，这些都不起作用。
我认为第二个错误来自于这个事实......我在舞台上同时有2行。

我不知道从代码中粘贴到底是什么，所以我必须在FLA.fail的MainClass中推送所有内容：D但我做得很整齐！所以，如果有人帮助我，他会轻松跟踪代码
所以它是一个简单的FLA.fail，带有4个MC，在那个4 MC中没有代码 一颗子弹 一艘颜色为黄色的船 一个颜色为绿色的Ship2，所以我可以看到随机化 和一个类Turret的玩家
所以FLA的MainClass是：

我不知道如何解决这两个问题。非常感谢任何帮助！

对不起我问这个问题的方式（通过回答），但它很想发表评论@mitim。 所以我已经完成了你所说的并追踪了错误，但它现在才有意义（或者它对我有用）并且稍微改变了代码的排列。但是它再次给了我一个错误，我甚至无法理解为什么当它（对象）在那一点上甚至不存在。 更改了doShips（）的代码
//move the ships
protected function doShips() {
for (var i:int = shipArray.length - 1; i >= 0; i--) {
shipArray[i].y +=3 //make the Ships fall down
if(shipArray[i].y >120){ // stage.stageHeight)
removeChild(shipArray[i]);
shipArray.splice(i,1);
}
for (var bcount= _bulletsArray.length-1; bcount >= 0; bcount--) {
//if the bullet is touching the ship
if (shipArray[i].hitTestObject(_bulletsArray[bcount])) {
//if we get here it means there`s is a collision
removeChild(_bulletsArray[bcount]);
_bulletsArray.splice(bcount,1);
removeChild(shipArray[i]);
shipArray.splice(i,1);
}
}
}
}
当我控制移位 - 进入FLA并射击一些船只它给了我
TypeError: Error #1010: A term is undefined and has no properties.
at MainClass/doShips()[/Users/STouch/Desktop/MyWork/BattleShips/TestShips/11111111 Perks22/ShipArray/MainClass.as:112]
at MainClass/everyFrame()[/Users/STouch/Desktop/MyWork/BattleShips/TestShips/11111111 Perks22/ShipArray/MainClass.as:50]
那条线（112）是if (shipArray[i].hitTestObject(_bulletsArray[bcount])) {？！？！
为什么它会在此之前侦听我已经移除并拼接的元素（如果已经击中了船/盒，则将其拼接并从舞台上移除）
而奇怪的是，它每次都不会给我这个错误，只有当我拍摄2-3艘船并等待其余部分被移除时（超过舞台的120度）。就像我击中最后一艘船一样数组或第一个或类似的数组中有一个空白点。任何想法如何解决或现在做什么？
