"ts a uml i need for a space invaders clone........all them funky diagrams ......which i know very little about! i can attach more later?"

Sounds pretty depressing to read, let alone provide some help. If you are looking for help, what prevents you from detailing out what you need instead of short 1 liners ?

Sorry maybe its me - there could be others who can read a whole lot into your queries.
