FLASH CS3 - Action Script part 2

try read this first

Now we have fl001.as and fl001.fla
we use the fl001.fla and now we will continue!! In first tutorial you should ask, what the heck is that code.. actualy my friend.. that's is an example, but learning from now isn't good as basic tutorial for Flash AS 3. For review, we have code like this

---

package {
    import flash.display.Sprite;
    public class fl005 extends Sprite {
        public function fl005(  ) {
    
        }//  public function fl005(  )

    } // public class fl005 extends Sprite
} //package

sory less color.. I will try to explain.. This structure will be same for next actionscript.
Package

In the beginning we should type package, because this  action script treat as package

import

import mean to include whatever script, dll or something that help you script

public

this mean, the class or function that have status public can be called easy from outside. You can use Private to avoid the class called outsite the area.

public class

or we called as class.. it mean this is the name of class.. the class name should be same as filename to avoid error and missleading script and you should type this is extend from what?  Sprite? Movie? or what

Public function

or we called as function. Function is a task that able to return value or not (that's depend your code), since your class have name fl005. You should type function fl005. this function will be called at first.. just like function _construct on PHP

For closing.. Let's try this..

---

package {
    import flash.display.Sprite;
    public class fl002 extends Sprite {
        public function fl002(  ) {           
         var userName:String = "Bill Smith";
                  trace("My name is " + userName + ".");

        }//  public function fl005(  )

    } // public class fl005 extends Sprite {
} //package

Next I will describe about variable type..
