Work the Shell - Recognizing Blackjacks
We've run out of space for this column, but all that's left is to implement the overall play logic. The game as it stands now shuffles the deck, deals cards for the player and dealer, lets the player add new cards (“hit” in Blackjack parlance) until he or she is satisfied or exceeds 21 points, and shows the dealer hand. Next column, we'll write the loop that lets the dealer play out its hand and determine who won the hand. No doubt we'll sneak in some interface features too, of course, but one way or the other, next column will be a wrap for this particular scripting project.
This means I'll be ready to tackle something new! If you have a particular scripting project you think could be an interesting study, please drop me an e-mail, and I'll consider it for a future column series. Otherwise, I've been eyeing the game Yahtzee pretty closely.
