Question

I’ve got a AS3 program with a Main.as custom class.

In this class I load an instance of a ‘menu’ movieclip which has simpleButton instances inside… How do I access the Main class public functions by the menu movieclip buttons?

I.e. Menu button -> gotoPage(5); (which is a Main public function)

If I try to access the Main function with the above statement, it gives

“1180: Call to a possibly undefined method gotoPage.

Answer 1

Create a static method called GetMain() on the Main class that would return the instance of Main (Main should be a singleton).

package whatever
{
  public class Main
  {
    private static var _instance:Main = null;

    public static function getMain():Main
    {
      return _instance;
    }

    // Main constructor
    function Main(..):void
    {
      _instance = this;
    }
  }
}

To refer to the instance of Main() from your Menu class, you could use:

Main.getMain().gotoPage(5);
