=head2 ATTACHABLE OBJECTS |
209 |
|
210 |
Many objects in crossfire are so-called attachable objects. That means you can |
211 |
attach callbacks/event handlers (a collection of which is called an "attachment") |
212 |
to it. All such attachable objects support the following methods. |
213 |
|
214 |
In the following description, CLASS can be any of C<global>, C<object> |
215 |
C<player>, C<client> or C<map> (i.e. the attachable objects in |
216 |
crossfire+). |
217 |
|
218 |
=over 4 |
219 |
|
220 |
=item $attachable->attach ($attachment, key => $value...) |
221 |
|
222 |
=item $attachable->detach ($attachment) |
223 |
|
224 |
Attach/detach a pre-registered attachment to a specific object and give it |
225 |
the specified key/value pairs as arguments. |
226 |
|
227 |
Example, attach a minesweeper attachment to the given object, making it a |
228 |
10x10 minesweeper game: |
229 |
|
230 |
$obj->attach (minesweeper => width => 10, height => 10); |
231 |
|
232 |
=item $bool = $attachable->attached ($name) |
233 |
|
234 |
Checks wether the named attachment is currently attached to the object. |
235 |
|
236 |
=item cf::CLASS->attach ... |
237 |
|
238 |
=item cf::CLASS->detach ... |
239 |
|
240 |
Define an anonymous attachment and attach it to all objects of the given |
241 |
CLASS. See the next function for an explanation of its arguments. |
242 |
|
243 |
You can attach to global events by using the C<cf::global> class. |
244 |
|
245 |
Example, log all player logins: |
246 |
|
247 |
cf::player->attach ( |
248 |
on_login => sub { |
249 |
my ($pl) = @_; |
250 |
... |
251 |
}, |
252 |
); |
253 |
|
254 |
Example, attach to the jeweler skill: |
255 |
|
256 |
cf::object->attach ( |
257 |
type => cf::SKILL, |
258 |
subtype => cf::SK_JEWELER, |
259 |
on_use_skill => sub { |
260 |
my ($sk, $ob, $part, $dir, $msg) = @_; |
261 |
... |
262 |
}, |
263 |
); |
264 |
|
265 |
=item cf::CLASS::attachment $name, ... |
266 |
|
267 |
Register an attachment by C<$name> through which attachable objects of the |
268 |
given CLASS can refer to this attachment. |
269 |
|
270 |
Some classes such as crossfire maps and objects can specify attachments |
271 |
that are attached at load/instantiate time, thus the need for a name. |
272 |
|
273 |
These calls expect any number of the following handler/hook descriptions: |
274 |
|
275 |
=over 4 |
276 |
|
277 |
=item prio => $number |
278 |
|
279 |
Set the priority for all following handlers/hooks (unless overwritten |
280 |
by another C<prio> setting). Lower priority handlers get executed |
281 |
earlier. The default priority is C<0>, and many built-in handlers are |
282 |
registered at priority C<-1000>, so lower priorities should not be used |
283 |
unless you know what you are doing. |
284 |
|
285 |
=item type => $type |
286 |
|
287 |
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
288 |
given type of objects only (the additional parameter C<subtype> can be |
289 |
used to further limit to the given subtype). |
290 |
|
291 |
=item on_I<event> => \&cb |
292 |
|
293 |
Call the given code reference whenever the named event happens (event is |
294 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
295 |
handlers are recognised generally depends on the type of object these |
296 |
handlers attach to). |
297 |
|
298 |
See F<include/eventinc.h> for the full list of events supported, and their |
299 |
class. |
300 |
|
301 |
=item package => package:: |
302 |
|
303 |
Look for sub functions of the name C<< on_I<event> >> in the given |
304 |
package and register them. Only handlers for eevents supported by the |
305 |
object/class are recognised. |
306 |
|
307 |
=back |
308 |
|
309 |
Example, define an attachment called "sockpuppet" that calls the given |
310 |
event handler when a monster attacks: |
311 |
|
312 |
cf::object::attachment sockpuppet => |
313 |
on_skill_attack => sub { |
314 |
my ($self, $victim) = @_; |
315 |
... |
316 |
} |
317 |
} |
318 |
|
319 |
=item $attachable->valid |
320 |
|
321 |
Just because you have a perl object does not mean that the corresponding |
322 |
C-level object still exists. If you try to access an object that has no |
323 |
valid C counterpart anymore you get an exception at runtime. This method |
324 |
can be used to test for existence of the C object part without causing an |
325 |
exception. |

C<rent::overview>, as used by the C<rent> extension. |

=head2 EXTENSION DATABASE SUPPORT |
1115 |
|
1116 |
Crossfire maintains a very simple database for extension use. It can |
1117 |
currently store anything that can be serialised using Storable, which |
1118 |
excludes objects. |
1119 |
|
1120 |
The parameter C<$family> should best start with the name of the extension |
1121 |
using it, it should be unique. |
1122 |
|
1123 |
=over 4 |
1124 |
|
1125 |
=item $hashref = cf::db_get $family |
1126 |
|
1127 |
Return a hashref for use by the extension C<$family>, which can be |
1128 |
modified. After modifications, you have to call C<cf::db_dirty> or |
1129 |
C<cf::db_sync>. |
1130 |
|
1131 |
=item $value = cf::db_get $family => $key |
1132 |
|
1133 |
Returns a single value from the database |
1134 |
|
1135 |
=item cf::db_put $family => $hashref |
1136 |
|
1137 |
Stores the given family hashref into the database. Updates are delayed, if |
1138 |
you want the data to be synced to disk immediately, use C<cf::db_sync>. |
1139 |
|
1140 |
=item cf::db_put $family => $key => $value |
1141 |
|
1142 |
Stores the given C<$value> in the family hash. Updates are delayed, if you |
1143 |
want the data to be synced to disk immediately, use C<cf::db_sync>. |
1144 |
|
1145 |

Marks the database as dirty, to be updated at a later time. |
