A simple little game inspired by pmichauds talks at YAPC-NA in Pittsburgh.


#!/usr/local/bin/perl6

my $guesses = 5;

say qq{{{{{

A Hurkle is hiding on a 10 by 10 grid.  The south-west corner of the g
+rid is
point 0,0 and any gridpoint is a pair of whole numbers seperated by a 
+comma.
Try to guess the Hurkle's gridpoint.  You get $guesses tries.  After e
+ach try,
I will tell you the approximate direction to go to look for the Hurkle
+.

}}}}};

my $guess = 0;

my $hurkle_x = 10.rand.int;
my $hurkle_y = 10.rand.int;

regex digit     { [0..9] };
regex seperator { \s* ',' \s* };

while ($guess++ != $guesses)  {

    my $input = prompt "Guess #$guess  ";
    $input ~~ / $<x>=<digit> <seperator> $<y>=<digit> /;

    unless ( ?$<x> && ?$<y> ) {
        say 'Huh?';
        redo;
    }

    if ( ($<x> - $hurkle_x).abs + ($<y> - $hurkle_y).abs == 0) {
        say "\nYou found him in $guess guesses!";
        exit 0;
    }

    say 'Go ', ($<y> < $hurkle_y)
        ?? 'North'
        !! ($<y> > $hurkle_y)
            ?? 'South'
