Actionscript 3 《捕手游戏生活》获胜'；t更新为3.0

我正在尝试创建一个简单的捕手游戏。我已经弄清了基本结构/逻辑，但我面临一些问题。由于某些原因，生活没有像我希望的那样更新。只有当“好”的起重机从屏幕顶部离开时，它们才会真正工作，然后减少一个。但除此之外（抓一只“坏”起重机或抓一只“正”起重机）并没有减少或增加1。同样，分数似乎适用于“好”起重机，加上我指定的分数，但不适用于“坏”或“加”起重机

我错过了什么？救命啊

if（timer）而不是依赖文本，说trace（totalives）；当我跟踪totalives时，我只得到totalives的答案-1，当“好”起重机从顶部退出舞台时发生。其他任何东西都不会带来值。我还跟踪了newCrane.typestr，看看它是否识别出“坏”和“加”起重机，但它不会返回“未识别”，但它跟踪“好”，我认为if语句不足以捕捉冲突。我使用的最新版本Flash是MX，因此我对正确的语法有点生疏，但您应该考虑在捕捉器中添加一个用于碰撞/碰撞对象的eventlistener。如果它命中任何内容，请检查哪种类型的crane。
