Hello Folks and thanks for looking into this post.

My situation:
I used to work a lot with AS2, unfortunately never got to get into AS3 after that.
Now I would like to make an example for a presentation and at the same time I would like to freshen up my AS skills.
I tried to find tutorials or similar to what I need but unfortunately I was not lucky at all.
Here is what I want to do:

Randomly spawn 10 black and 10 white circles or squares in a container and make them move in random directions, same speed, bouncing off the walls.
And here comes the action:
If black ball hits white ball, both balls splits in 2 smaller balls.
If same color hits same color, they merge to a bigger ball.

I would be very thankful if someone could make me an tutorial or link me some that could help me out with this.

Thanks a lot in advance!
