209
210Many objects in crossfire are so-called attachable objects. That means you can
211attach callbacks/event handlers (a collection of which is called an "attachment")
212to it. All such attachable objects support the following methods.
213
214In the following description, CLASS can be any of C<global>, C<object>
215C<player>, C<client> or C<map> (i.e. the attachable objects in
216crossfire+).

136=item $object->attach ($attachment, key => $value...)
137
138=item $object->detach ($attachment)
139
140Attach/detach a pre-registered attachment to an object.
141
142=item $player->attach ($attachment, key => $value...)
143
144=item $player->detach ($attachment)

149 221
150=item $map->detach ($attachment) 222=item $attachable->detach ($attachment)
151 223
152Attach/detach a pre-registered attachment to a map. 224Attach/detach a pre-registered attachment to a specific object and give it
225the specified key/value pairs as arguments.
153 226
154=item $bool = $object->attached ($name) 227Example, attach a minesweeper attachment to the given object, making it a
22810x10 minesweeper game:
155 229
156=item $bool = $player->attached ($name) 230 $obj->attach (minesweeper => width => 10, height => 10);
157 231
158=item $bool = $map->attached ($name) 232=item $bool = $attachable->attached ($name)

163 237
164Attach handlers for global events. 238=item cf::CLASS->detach ...

166This and all following C<attach_*>-functions expect any number of the 240Define an anonymous attachment and attach it to all objects of the given
167following handler/hook descriptions: 241CLASS. See the next function for an explanation of its arguments.
242
243You can attach to global events by using the C<cf::global> class.
244
245Example, log all player logins:
246
247 cf::player->attach (
248 on_login => sub {
249 my ($pl) = @_;
250 ...
251 },
252 );
253
254Example, attach to the jeweler skill:
255
256 cf::object->attach (
257 type => cf::SKILL,
258 subtype => cf::SK_JEWELER,
259 on_use_skill => sub {
260 my ($sk, $ob, $part, $dir, $msg) = @_;
261 ...
262 },
263 );
264
265=item cf::CLASS::attachment $name, ...
266
267Register an attachment by C<$name> through which attachable objects of the
268given CLASS can refer to this attachment.
269
270Some classes such as crossfire maps and objects can specify attachments
271that are attached at load/instantiate time, thus the need for a name.
272
273These calls expect any number of the following handler/hook descriptions:

175earlier. The default priority is C<0>, and many built-in handlers are 281earlier. The default priority is C<0>, and many built-in handlers are

177unless you know what you are doing. 283unless you know what you are doing.
178 284
285=item type => $type
286
287(Only for C<< cf::object->attach >> calls), limits the attachment to the
288given type of objects only (the additional parameter C<subtype> can be
289used to further limit to the given subtype).

310event handler when a monster attacks:
198 311
199Attach handlers for a specific object type (e.g. TRANSPORT) and 312 cf::object::attachment sockpuppet =>
