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+). |

145 | |
164 | |
146 | =item $bool = $player->attached ($name) |

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

|
|
181 | |
