ActionScript 3 class over multiple files - how?

So how do I write a class over multiple files in script 3 action?

There is a "partial" keyword in C #.

In C ++ this is natural (you just "#include ..." all files).

In Flex 3, the component you add this tag: <mx:Script source="myfile.as"/>

.

How to split the following class into multiple files:

package package_path
{
    public class cSplitMeClass
    {
        public function cSplitMeClass()
        {
        }

        public function doX():void
        {
            // ....
        }

        public function doY():void
        {
            // ....
        }
    }
}

For example, I want to have doX () and doY () functions implemented in another .as file.

Can I do it?

And please don't tell me something like "it's a good practice to have them in the same file" :)

As per your request, I will spare you a "best practices lecture". So, I'll just say what to include directive in AS 3.0, which might help you here.

Basically, you can do:

package package_path
{
    public class cSplitMeClass
    {
        public function cSplitMeClass()
        {
        }

        include "the_file_where_doX_and_doY_live.as"
     }
}


And then in "the_file_where_doX_and_doY_live.as" 

    public function doX():void
    {
        // ....
    }

    public function doY():void
    {
        // ....
    }

You can do it with inheritance:



// file: cSplitMe1.as

class cSplitMe1 {

   function doX() {
       // ...
   }

// file: cSplitMe2.as

class cSplitMe2 extends cSplitMe1 {

   function doY() {
       // ...
   }

// file: cSplitMe.as

class cSplitMe extends cSplitMe2 {

   function cSplitMe() {
       doX();
       doY();
   }
}

This is good practice, nothing wrong with that.

Here is the key word import

. Example:

import Class_A.as;
import Class_B.as;

Now, of course, in order to use them, you need to declare them, preferably in your constructor.

public function Class_C()
{
    //Create a new instance of Class_A
    var objA:Object = new Class_A("parameter one", "parameter two");
    //Create a new instance of Class_B
    var objA:Object = new Class_B("parameter one", "parameter two");
}

Of course, it all depends on how you are going to do this job. I also suggest that you use a main class from which you can run your code. I think you already knew that.

Good luck.
