240 | =head2 ATTACHABLE OBJECTS |
|
|
241 | |
|
|
242 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
243 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
244 | to it. All such attachable objects support the following methods. |
|
|
245 | |
|
|
246 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
247 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
248 | crossfire+). |
|

251 | |
110 | =item $object->attach ($attachment, key => $value...) |
252 | =item $attachable->attach ($attachment, key => $value...) |
111 | |
253 | |
112 | Attach a pre-registered attachment to an object. |
254 | =item $attachable->detach ($attachment) |
113 | |
255 | |
114 | =item $player->attach ($attachment, key => $value...) |
256 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
257 | the specified key/value pairs as arguments. |
115 | |
258 | |
116 | Attach a pre-registered attachment to a player. |
259 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
260 | 10x10 minesweeper game: |
117 | |
261 | |
118 | =item $map->attach ($attachment, key => $value...) # not yet persistent |
262 | $obj->attach (minesweeper => width => 10, height => 10); |
119 | |
263 | |
120 | Attach a pre-registered attachment to a map. |
264 | =item $bool = $attachable->attached ($name) |
121 | |
265 | |
122 | =item cf::attach_global ... |
266 | Checks wether the named attachment is currently attached to the object. |
123 | |
267 | |
124 | Attach handlers for global events. |
268 | =item cf::CLASS->attach ... |
125 | |
269 | |
126 | This and all following C<attach_*>-functions expect any number of the |
270 | =item cf::CLASS->detach ... |
127 | following handler/hook descriptions: |
271 | |
|
|
272 | Define an anonymous attachment and attach it to all objects of the given |
|
|
273 | CLASS. See the next function for an explanation of its arguments. |
|
|
274 | |
|
|
275 | You can attach to global events by using the C<cf::global> class. |
|
|
276 | |
|
|
277 | Example, log all player logins: |
|
|
278 | |
|
|
279 | cf::player->attach ( |
|
|
280 | on_login => sub { |
|
|
281 | my ($pl) = @_; |
|
|
282 | ... |
|
|
283 | }, |
|
|
284 | ); |
|
|
285 | |
|
|
286 | Example, attach to the jeweler skill: |
|
|
287 | |
|
|
288 | cf::object->attach ( |
|
|
289 | type => cf::SKILL, |
|
|
290 | subtype => cf::SK_JEWELER, |
|
|
291 | on_use_skill => sub { |
|
|
292 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
293 | ... |
|
|
294 | }, |
|
|
295 | ); |
|
|
296 | |
|
|
297 | =item cf::CLASS::attachment $name, ... |
|
|
298 | |
|
|
299 | Register an attachment by C<$name> through which attachable objects of the |
|
|
300 | given CLASS can refer to this attachment. |
|
|
301 | |
|
|
302 | Some classes such as crossfire maps and objects can specify attachments |
|
|
303 | that are attached at load/instantiate time, thus the need for a name. |
|
|
304 | |
|
|
305 | These calls expect any number of the following handler/hook descriptions: |
