145 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
146 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
147 | to it. All such attachable objects support the following methods. |
|
|
148 | |
|
|
149 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
150 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
151 | crossfire+). |

138 | =item $bool = $object->attached ($name) |
162 | Example, attach a minesweeper attachment to the given object, making it a |
|

163 | 10x10 minesweeper game: |
139 | |
164 | |
140 | =item $bool = $player->attached ($name) |

177 | |
|
|
178 | You can attach to global events by using the C<cf::global> class. |
|
|
179 | |
|

180 | Example, log all player logins: |
|
|
181 | |
|
|
182 | cf::player->attach ( |
|

191 | cf::object->attach ( |
|
