Dam thats usful, it’s been a few years since I’ve done any AS2 programing and now have met someone who insists on using it for a project. It’s taken me hours to get my head back into AS2 thinking. I was completly stumped on extending MovieClip, thanks a million.

Hi Paul,

thanks for the post…had some as2 code that needed some changes and converting it to as3 was not really an option. The as3 way is a bit more logical and my as2 is weak, so I thought I was close….then I read your post and that worked!! I had to add ‘new’ operator in the class tho…

Hi! Can I call addChild to add an instance to the stage in it’s own constructor method?

In other words… Can you call addChild, somehow, in the triangle’s constructor to add automatically the triangle’s instance to the stage once it’s created?

Thanks for the post and for your answer,

@Martin

I think the reason is the folowing.

Your parameters are set correctly through initialization object, however you do overwrite them with ‘undefined’ values when your constructor is called.

Try making your constructor empty:

public function Dot(){
}

Hope that helped
