241
242Many objects in crossfire are so-called attachable objects. That means you can
243attach callbacks/event handlers (a collection of which is called an "attachment")
244to it. All such attachable objects support the following methods.
245
246In the following description, CLASS can be any of C<global>, C<object>
247C<player>, C<client> or C<map> (i.e. the attachable objects in
248crossfire+).

134=item $object->attach ($attachment, key => $value...)
135
136=item $object->detach ($attachment)
137
138Attach/detach a pre-registered attachment to an object.
139
140=item $player->attach ($attachment, key => $value...)
141
142=item $player->detach ($attachment)

149 255
150Attach/detach a pre-registered attachment to a map. 256Attach/detach a pre-registered attachment to a specific object and give it
257the specified key/value pairs as arguments.
151 258
152=item $bool = $object->attached ($name) 259Example, attach a minesweeper attachment to the given object, making it a
26010x10 minesweeper game:
153 261
154=item $bool = $player->attached ($name) 262 $obj->attach (minesweeper => width => 10, height => 10);

164This and all following C<attach_*>-functions expect any number of the 272Define an anonymous attachment and attach it to all objects of the given
165following handler/hook descriptions: 273CLASS. See the next function for an explanation of its arguments.
274
275You can attach to global events by using the C<cf::global> class.
276
277Example, log all player logins:
278
279 cf::player->attach (
280 on_login => sub {
281 my ($pl) = @_;
282 ...
283 },
284 );
285
286Example, attach to the jeweler skill:
287
288 cf::object->attach (
289 type => cf::SKILL,
290 subtype => cf::SK_JEWELER,
291 on_use_skill => sub {
292 my ($sk, $ob, $part, $dir, $msg) = @_;
293 ...
294 },
295 );
296
297=item cf::CLASS::attachment $name, ...
298
299Register an attachment by C<$name> through which attachable objects of the
300given CLASS can refer to this attachment.
301
302Some classes such as crossfire maps and objects can specify attachments
303that are attached at load/instantiate time, thus the need for a name.
304
305These calls expect any number of the following handler/hook descriptions:

173earlier. The default priority is C<0>, and many built-in handlers are 313earlier. The default priority is C<0>, and many built-in handlers are

176 316
317=item type => $type
318
319(Only for C<< cf::object->attach >> calls), limits the attachment to the
320given type of objects only (the additional parameter C<subtype> can be
321used to further limit to the given subtype).
