我在一个侧面滚动游戏项目，但我一直在努力与AS文件。首先，我没有在主时间线第一帧上编码，我使用外部作为整个项目的文件。
到目前为止，我有2个单独的文件，主要一个名为Tuan.as，另一个名为Enemy.as
我单独使用Tuan.as文件运行没有问题，但是当我决定添加更多功能时，比如使用另一个名为Enemy.as的文件添加敌人，我无法正确导入它们。我收到错误＆＃34;调用可能未定义的方法addEnemytoLevel1＆＃34;
这是我整个游戏的代码，第一个文件Tuan.as：

// 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
}
}
}
如果我不想说非常糟糕，我不太擅长AS，我无法弄清楚如何让它发挥作用，非常感谢你的帮助。答案 0 :(得分：0)
我认为你的意思是addEnemiesToLevel1()（将敌人添加到1级）而不是addEnemytoLevel1()，你不能这样调用它，如果在你的内部使用它应该在你的类的另一个函数内调用，在您的情况下，您可以在构造函数中调用它：
public function Tuan()
{
// ...
addEnemiesToLevel1();
}
希望可以提供帮助。
