addChild from class

Hi, I'm trying to 'addchild' (a circle shape) to the stage from a class that's not the main project class. Maybe this is a bad idea... I'm not sure. Anyway, my code isn't working, yet there are no errors. Here's it is below. Any suggestions would be appreciated.

Code:

---

package  {
       
        import flash.display.MovieClip;
        import flash.display.Shape;
       
       
        public class main extends MovieClip {
               
                var circle3:Shape = new Shape();
               
                public function main() {
                        // constructor code
                       
                        circle3.graphics.beginFill(0xefefef, 1);
                        circle3.graphics.drawCircle(100,100,50);
                        circle3.graphics.endFill();
                        addChild(circle3);
                }
        }
       
}

Hi,
It does work, you probably can't see the circle, changes colours to test

Hi Fruitbeard, I accidentally posted the wrong code. Here's the actual code in error. It's a class outside of the main project class attempting to draw a circle on the stage. No circle is drawn and no error messages are generated.

Code:

---

package  {
       
        import flash.display.Shape;       
       
        public class makeCirc extends Shape {
               
                var circle3:Shape = new Shape();

                public function makeCirc() {
                        // constructor code
                        circle3.graphics.beginFill(0xff0000, 1);
                        circle3.graphics.drawCircle(200,200,50);
                        circle3.graphics.endFill();
                        stage.addChild(circle3);
                }

        }
       
}

Hi,

I'm not sure how you have your other files??

Main.as

PHP Code:

---

package 
{
    import flash.display.Sprite;
    public class Main extends Sprite
    {
        public var circle3:makeCirc = new makeCirc();
        public function Main()
        {
            addChild(circle3);
        }
    }
} 


---

makeCirc.as

PHP Code:

---

package 
{
    import flash.display.Sprite;
    public class makeCirc extends Sprite
    {
        function makeCirc():void
        {
            var circle:Sprite = new Sprite();
            circle.graphics.beginFill(0xff0000,1);
            circle.graphics.drawCircle(200,200,50);
            circle.graphics.endFill();
            addChild(circle);
        }
    }
}

Thanks Fruitbeard, This seems like your suggestion would work. I just wanted to have the class that wasn't the main class, addchild, to keep classes as encapsulated as possible. Maybe what I was trying to do it bad practice. Not sure.

Yeah... I'd really like to learn how to encapsulate more to take advantage of the OOP aspect of as3. Doesn't seem like most tutorials or developer do this.

I think this is what you're asking...

Flash movieclips are oop. So when you work with movieclips you're doing oop.

The main movieclip is an instance of the main class. So you can have your main mc (the main class) load other classes but they'll be children of main mc.

So, everything that you draw, code, or add to the "stage" in authoring, is a child of main. You're referencing everything from Main so you don't need to add main. to everything.

In oop, you're not supposed to reference the parents - no encapsulation. You use events - this button has been pressed. When learning or developing, you need to do it. You can use MovieClip(parent)
