150 | =head2 ATTACHABLE OBJECTS |
|
|
151 | |
|
|
152 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
153 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
154 | to it. All such attachable objects support the following methods. |
|
|
155 | |
|
|
156 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
157 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
158 | crossfire+). |
|
|
159 | |
|
|
160 | =over 4 |
|
|
161 | |
110 | =item $object->attach ($attachment, key => $value...) |
162 | =item $attachable->attach ($attachment, key => $value...) |
111 | |
163 | |
112 | Attach a pre-registered attachment to an object. |
164 | =item $attachable->detach ($attachment) |
113 | |
165 | |
114 | =item $player->attach ($attachment, key => $value...) |
166 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
167 | the specified key/value pairs as arguments. |
115 | |
168 | |
116 | Attach a pre-registered attachment to a player. |
169 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
170 | 10x10 minesweeper game: |
117 | |
171 | |
118 | =item $map->attach ($attachment, key => $value...) # not yet persistent |
172 | $obj->attach (minesweeper => width => 10, height => 10); |
119 | |
173 | |
120 | Attach a pre-registered attachment to a map. |
174 | =item $bool = $attachable->attached ($name) |
121 | |
175 | |
122 | =item cf::attach_global ... |
176 | Checks wether the named attachment is currently attached to the object. |
123 | |
177 | |
124 | Attach handlers for global events. |
178 | =item cf::CLASS->attach ... |
125 | |
179 | |
126 | This and all following C<attach_*>-functions expect any number of the |
180 | =item cf::CLASS->detach ... |
127 | following handler/hook descriptions: |
181 | |
|
|
182 | Define an anonymous attachment and attach it to all objects of the given |
|
|
183 | CLASS. See the next function for an explanation of its arguments. |
|
|
184 | |
|
|
185 | You can attach to global events by using the C<cf::global> class. |
|
|
186 | |
|
|
187 | Example, log all player logins: |
|
|
188 | |
|
|
189 | cf::player->attach ( |
|
|
190 | on_login => sub { |
|
|
191 | my ($pl) = @_; |
|
|
192 | ... |
|
|
193 | }, |
|
|
194 | ); |
|
|
195 | |
|
|
196 | Example, attach to the jeweler skill: |
|
|
197 | |
|
|
198 | cf::object->attach ( |
|
|
199 | type => cf::SKILL, |
|
|
200 | subtype => cf::SK_JEWELER, |
|
|
201 | on_use_skill => sub { |
|
|
202 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
203 | ... |
|
|
204 | }, |
|
|
205 | ); |
|
|
206 | |
|
|
207 | =item cf::CLASS::attachment $name, ... |
|
|
208 | |
|
|
209 | Register an attachment by C<$name> through which attachable objects of the |
|
|
210 | given CLASS can refer to this attachment. |
|
|
211 | |
|
|
212 | Some classes such as crossfire maps and objects can specify attachments |
|
|
213 | that are attached at load/instantiate time, thus the need for a name. |
|
|
214 | |
|
|
215 | These calls expect any number of the following handler/hook descriptions: |

136 | registered at priority C<-1000>, so lower priorities should not be used |

251 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
252 | event handler when a monster attacks: |
158 | |
253 | |
159 | Attach handlers for a specific object type (e.g. TRANSPORT) and |

166 | very rare events, as handlers are (obviously) called for I<all> objects in |
