I currently have three weeks left ony my degree and the last thing i have to do is build a penalty shootout game with Actionscript 3.0.

I thought i would be able to do this but im having trouble getting my head round this.

I understand that i need to have a player, a ball, goalposts, a crowd and i need a scoring system.

I know all the basics but i have no idea how to actually go about making this a fully functional game, is there any tutorials on making a penalty shootout game? Ive searched all over but cannot find anything?
