Actionscript: Classes inside Classes

Question

i'm trying to create a flash game, but i'm having trouble with my classes. i'm importing the classes on the main script. they're imported okay, i've tested it all. but i dont know how to use classes inside another class

this is what i've got so far:

class Class.Player {
  public static var self:MovieClip;
  public static var bullet:Class.Bullet;

  function controls() {
    //Shoot
    if (Key.isDown(Key.SPACE)) {
      bullet = new Bullet(100, 100);
  }
}

it loads the class and declares the variable, but it claims "Bullet" is not an existing method. it is an existing method, and it works when i call it from the main script.

also, do i need to declare the class like public static var bullet:Class.Bullet;? it's the only way that works for me but wondered if there's a better way?

Answer 1

It looks like you are having problems with the naming of your classes. You don't have to call your classes Class.Name. Just use Name.

In your case, you could have a file called

Player.as

With this content:

package {
    import flash.display.MovieClip;

    public class Player extends MovieClip {
        public private var bullet:Bullet;

        public function Player(){
            //constructor
        }

        function controls() {
            //Shoot
            if (Key.isDown(Key.SPACE)) {
                bullet = new Bullet(100, 100);
            }
        }
    }
}

And then a file called

Bullet.as

With this content:

package {
    import flash.display.MovieClip;

    public class Bullet extends MovieClip {

        public function Bullet(x:Number, y:Number){
            //constructor
        }

    }
}

Answer 2

You're putting your package information in the Class name. I have no idea how this is even compiling for you (especially given that Class is a reserved word.

Your files should look more like:

package somePackage {//somePackage instead of the reserved word Class you were using

    import someOtherPackage.Bullet;

    public class Player extends MovieClip {
         public var bullet:Bullet;
         public function Player():void {
            super();
            //other constructor logic here
         }
    }

}
