我一直在根据教程制作塔防游戏。我完成了教程，它工作得很好，但我不知道如何建立它。所以我重新开始，建造了更多的塔和第二个敌人，但问题是在第一个关卡中这是可行的，但在第二个关卡中却行不通。我已经研究了几个小时了，但什么也没发现。所以我想问的是是否有人能给我一个教程或任何可能对数组和as3中的塔防游戏有帮助的东西它有很多代码所以我现在不会发布，除非你真的需要它
这里有教程http://www.flashgametuts.com/tutorials/as3/how-to-create-a-tower-defense-game-in-as3-part-1/

你需要创造轻松重置游戏状态的能力。删除侦听器(如果使用弱引用可能不需要;http://gskinner.com/blog/archives/2006/07/as3_weakly_refe.html)，清除数组，删除图形(removeChild)等。将所有内容存储在"level"对象中，并在其上使用dispose()(或类似)函数是一种很好的方法(如注释中所述)。然后简单地为下一个关卡创建一个新的关卡对象，你就可以开始了:)
我猜你遇到的问题是，在你开始下一关之前，你没有正确地从关卡中删除所有内容。
"游戏的加载"应该是这样的:
- 设置所有游戏内静态资产。(HUD, Tiles等)
- 设置所有塔元素(购买塔面板) 设置所有敌人元素。(创建数组表示生成的敌人)
- 继续设置你在游戏中的所有其他元素。
玩家玩完这个关卡后，无论输赢，你都应该删除所有在"加载"阶段添加的东西。
这里的想法是，你希望所有内容，每个新关卡，都以完全相同的方式加载，每次你都对关卡设计进行小改动。像敌人和塔资产这样的东西总是以同样的方式加载，所以你需要确保在下一轮开始之前正确地删除它们，这样当你在下一轮添加它们时，你就不会重新添加一些仍然存在的东西。
你似乎对游戏设计很困惑。我上面提到的问题只是开始设计游戏时遇到的众多问题之一。我建议你阅读游戏设计书籍。我推荐这款。我推荐这类书的原因是，它能引导你了解游戏设计的概念部分，让你正确思考。我从这本书中学习了游戏编程，最近编写了《symphony Tower Defense》。
