118 | @match hi |

119 | @cond grep $_->name =~ /royalty/, $who->inv |
|
|
120 | You got royalties there! Wanna have! |
|
|
121 | |
|
|
122 | You may want to change the C<name> method there to something like C<title>, |
|
|
123 | C<slaying> or any other method that is allowed to be called on a |
|
|
124 | C<cf::object> here. |

128 | @match found earhorn |

129 | @cond grep $_->slaying =~ /Gramp's walking stick/, $who->inv |
|
|
130 | @eval my @g = grep { $_->slaying =~ /Gramp's walking stick/ } $who->inv; $g[0]->decrease; |
|
|
131 | Thanks for the earhorn! |
|
|
132 | |
|
|
133 | This example is a bit more complex. The C<@eval> statement will search |
|
|
134 | the players inventory for the same term as the C<@cond> and then |
|
|
135 | decreases the number of objects used there. |

|

138 | used in the real world :-) |
