As3 Error 5000 on class?

Question

So I tried to class an as3.file with my .fla (via QuickKong)

This error occurred:

**C:\Users\Lenovo\Desktop\To A Million\QuickKong.as, Line 1 5000: The class 'QuickKong' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type.**

Then I import: import flash.events.MouseEvent;

The error became this.

How do I interpret and fix this error? I have path to the file. The .fla has recogonized the file within the fla .

The AS File

Answer 1

add this to your code:

import flash.display.MovieClip;

and change public class into this:

public class QuickKong extends MovieClip
