即时通讯工作在侧滚动游戏项目，但我一直在努力与AS文件。首先，我没有在主要时间线框架上编码，我使用外部作为整个项目的文件。“调用一个可能未定义的方法” - 大项目
到目前为止，我有2个独立的文件，主要的一个名为Tuan.as，另一个Enemy.as
我有Tuan.as运行没有问题的文件单独然而，当我决定增加更多的功能游戏就像使用另一个名为Enemy.as的文件添加敌人一样，我无法正确导入它们。我得到了错误“调用可能未定义的方法addEnemytoLevel1”
这里是我的整个游戏的代码，第一个文件Tuan.as：

，这是该Enemy.as文件：
package{

import flash.events.Event;
public class Enemy extends MovieClip{
public function Enemy(xLocation:int, yLocation:int)
{
// constructor code
x = xLocation;
y = yLocation;
addEventListener(Event.ENTER_FRAME, loop);
}
public function loop(e:Event):void
{
//the looping code goes here
}
public function removeSelf():void
{
trace("remove self");
removeEventListener(Event.ENTER_FRAME, loop); //stop the loop
this.parent.removeChild(this); //tell this object's "parent object" to remove this object
}
}
}
即时通讯如果不想说非常糟糕，我不会很擅长，我不知道如何让它工作，非常感谢您的帮助。
