Games::Bowling::Scorecard - score your bowling game easily
use Games::Bowling::Scorecard; my $card = Games::Bowling::Scorecard->new; $card->record(6,1); # slow start $card->record(7,2); # getting better $card->record(10); # strike! $card->record(9,1); # picked up a spare $card->record(10) for 1 .. 3; # turkey! $card->record(0,0); # clearly distracted by something $card->record(8,2); # amazingly picked up 7-10 split $card->record(10, 9, 1); # pick up a bonus spare printf "total score: %u\n", $card->score; # total score: 156, lousy!
Scoring ten-pin bowling can be confusing for new players. Frames can't always be scored until several frames later, and then there's that weird tenth frame. Modern bowling alleys incorporate computer scoring into the pin cleanup mechanism, so it's easy to just concentrate on throwing a perfect game and not on grease-pencilling the sheet for the overhead.
What's one to do, though, when bowling cantaloupes at beer bottles in one's back yard? Now, with Games::Bowling::Scorecard, it's easy to improvise a scoring device -- maybe on a mobile phone running Symbian Perl.
This returns a new scorecard object. It does not take any arguments.
my @frames = $card->frames;
This method returns all of the frames for the game. This will return all frames in which scores have been recorded, and possibly one final frame with no recorded balls. It will never return any frames after that.
Frames are returned as Games::Bowling::Scorecard::Frame objects.
The current frame is the frame into which the next ball will be recorded. If the card is done, this method returns false.
This method returns any completed frames the score of which has not yet been finalized. This includes spares and strikes, before the next ball or balls have been recorded.
This method makes a record of a ball or balls. It is passed a list of bowling results, each being a number of pins knocked down by the ball.
$card->record(0, 0); # two gutter balls $card->record(6, 4); # a spare $card->record( (0, 0) x 10); # the worst game you could play $card->record( (10) x 12 ); # a perfect game
An exception will be raised if this method is called on a scorecard that's done.
This method returns the current score. It will include the tentative score for all pending frames.
my $score = $card->score_through($n)
This method returns the score as of the end of the nth frame. If that frame's cannot be definitively stated, because it is pending or not done, undef is returned.
This returns true if the scorecard is done. The scorecard is done if its contents indicate that the player's game is over.
maybe a way to indicate a split
In late 2006, I hadn't bowled in something like ten years. I got a Wii, and while I recognized the little triangle and X marks on the Wii Sports Bowling scorecard, I couldn't remember how on earth scoring worked. Once I thought I had a handle on it, I thought writing this would be a good way to cement it in my mind.
