My first pool game in corona

Hi,

I am trying to make my first pool billiards game in corona,

I have gone through some sample code and I really like the Lua language

In my pool game I want the player to play against the computer. That means that if the player one plays one shot the computer must autiomatically play the next shot. But I am not able to figure out how to make computer toake rounds and play shots automatically. I would be very grateful if someone lets me know how to make computer to take rounds,

I also want to know the difference between Corona Basic and Pro licence.

Thanks
