5006：ActionScript文件不能有多个外部可见定义：AND TypeError：错误＃1006：hitTestObject不是函数

Question

此代码中有2个问题。 首先是： 5006：ActionScript文件不能有多个外部可见定义：Sprayer，bugs

我已经将多个Actionscripts放在一起创建了这个，我已经分开了这些类，我希望在一个符号框架上播放它。

第二个涉及： 错误＃1006：hitTestObject不是函数

对于这个我试图让aagun / Sprayer失去健康然后生活，如果虫子触摸它，但我不知道为什么它说它不是一个功能。我用错了字吗？

5006：ActionScript文件不能有多个外部可见定义：Sprayer，bugs

正如它所说：文件中不能有多个公共定义。您必须将代码拆分为多个文件，或者将不需要公开的定义移出包中。

这可以在一个文件中找到：

package  
{   
    import flash.display.MovieClip; 
    // public is the default access modifier
    public class Test1 extends MovieClip 
    {   
        public function Test1() 
        {
            trace("test1");
            var t2:Test2 = new Test2();
            var t3:Test3 = new Test3();
        }
    }   
}

// Test2 and Test3 are defined outside of the package, otherwise it wouldn't compile.
// These definitions will only be visible to code in this file.

import flash.display.MovieClip;
class Test2 extends MovieClip 
{   
    public function Test2() 
    {
        trace("test2");
    }
}   

class Test3 extends MovieClip 
{   
    public function Test3() 
    {
        trace("test3");
    }
}

错误＃1006：hitTestObject不是函数

这通常意味着{I}没有在您试图从中调用它的对象（或它的祖先）上定义{尽管可能存在不同类型的错误）。

您的代码可以通过两种方式访问​​

hitTestObject()：hitTestObject()和airplanes.hitTestObject()。您必须调试代码以查看实际bullets[bulletNum].hitTestObject()和airplanes的内容，它们是什么类型以及它们是否继承bullets[bulletNum]方法。你至少可以hitTestObject()。
