I'm not an expert at actionscript, but is there a good place
to start for finding a tutorial about developing a flash game that
would simulate kicking a ball through goal posts? It would not be a
stand alone game, but just a teaser in a web banner that would
direct people to a site.
I suggest that you follow the online tutorials at
www.gamebrix.com where you can create a flash game using your web
browser. No programming is required. However, you can view the
actionscript that is generated for the game, edit or upload your
own Action scripts.
