106 | Here is a example: |

110 | =item B<matching for an item name> |

|
|
112 | @match hi |
|
|
113 | @cond grep $_->name =~ /royalty/, $who->inv |
|
|
114 | You got royalties there! Wanna have! |
|
|
115 | |
|
|
116 | You may want to change the C<name> method there to something like C<title>, |
|
|
117 | C<slaying> or any other method that is allowed to be called on a |
|
|
118 | C<cf::object> here. |
|
|
119 | |
|
|
120 | =item B<matching for an item name and removing the matched item> |
|
|
121 | |
|
|
122 | @match found earhorn |
|
|
123 | @cond grep $_->slaying =~ /Gramp's walking stick/, $who->inv |
|
|
124 | @eval my @g = grep { $_->slaying =~ /Gramp's walking stick/ } $who->inv; $g[0]->decrease; |
|
|
125 | Thanks for the earhorn! |
|
|
126 | |
|
|
127 | This example is a bit more complex. The C<@eval> statement will search |
|
|
128 | the players inventory for the same term as the C<@cond> and then |
|
|
129 | decreases the number of objects used there. |
|
|

131 | (See also the map: C<scorn/houses/cornerbrook.map> for an example how this is |
|
|
132 | used in the real world :-) |
