143 | =head2 ATTACHABLE OBJECTS |
109 | |
144 | |
110 | =item cf::attach_global ... |
145 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
146 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
147 | to it. All such attachable objects support the following methods. |
111 | |
148 | |
112 | =item cf::attach_to_type $object_type, ... |
149 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
150 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
151 | crossfire+). |
113 | |
152 | |
114 | =item cf::attach_to_objects ... |
153 | =over 4 |
115 | |
154 | |
116 | =item cf::attach_to_players ... |
155 | =item $attachable->attach ($attachment, key => $value...) |
117 | |
156 | |
118 | =item cf::attach_to_maps ... |
157 | =item $attachable->detach ($attachment) |
119 | |
158 | |
|
|
159 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
160 | the specified key/value pairs as arguments. |
|
|
161 | |
|
|
162 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
163 | 10x10 minesweeper game: |
|
|
164 | |
|
|
165 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
166 | |
|
|
167 | =item $bool = $attachable->attached ($name) |
|
|
168 | |
|
|
169 | Checks wether the named attachment is currently attached to the object. |
|
|
170 | |
|
|
171 | =item cf::CLASS->attach ... |
|
|
172 | |
|
|
173 | =item cf::CLASS->detach ... |
|
|
174 | |
|
|
175 | Define an anonymous attachment and attach it to all objects of the given |
|
|
176 | CLASS. See the next function for an explanation of its arguments. |
|
|
177 | |
|
|
178 | You can attach to global events by using the C<cf::global> class. |
|
|
179 | |
|
|
180 | Example, log all player logins: |
|
|
181 | |
|
|
182 | cf::player->attach ( |
|
|
183 | on_login => sub { |
|
|
184 | my ($pl) = @_; |
|
|
185 | ... |
|
|
186 | }, |
|
|
187 | ); |
|
|
188 | |
|
|
189 | Example, attach to the jeweler skill: |
|
|
190 | |
|
|
191 | cf::object->attach ( |
|
|
192 | type => cf::SKILL, |
|
|
193 | subtype => cf::SK_JEWELER, |
|
|
194 | on_use_skill => sub { |
|
|
195 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
196 | ... |
|
|
197 | }, |
|
|
198 | ); |
|
|
199 | |
120 | =item cf:register_attachment $name, ... |
200 | =item cf::CLASS::attachment $name, ... |
121 | |
201 | |
122 | prio => $number, # lower is earlier |
202 | Register an attachment by C<$name> through which attachable objects of the |
123 | on_xxx => \&cb, |
203 | given CLASS can refer to this attachment. |
|
|
204 | |
|
|
205 | Some classes such as crossfire maps and objects can specify attachments |
|
|
206 | that are attached at load/instantiate time, thus the need for a name. |
|
|
207 | |
|
|
208 | These calls expect any number of the following handler/hook descriptions: |
|
|
209 | |
|
|
210 | =over 4 |
|
|
211 | |
|
|
212 | =item prio => $number |
|
|
213 | |
|
|
214 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
215 | by another C<prio> setting). Lower priority handlers get executed |
|
|
216 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
217 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
218 | unless you know what you are doing. |
|
|
219 | |
|
|
220 | =item type => $type |
|
|
221 | |
|
|
222 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
223 | given type of objects only (the additional parameter C<subtype> can be |
|
|
224 | used to further limit to the given subtype). |
|
|
225 | |
|
|
226 | =item on_I<event> => \&cb |
|
|
227 | |
|
|
228 | Call the given code reference whenever the named event happens (event is |
|
|
229 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
230 | handlers are recognised generally depends on the type of object these |
|
|
231 | handlers attach to). |
|
|
232 | |
|
|
233 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
234 | class. |
|
|
235 | |
124 | package => package::, |
236 | =item package => package:: |
|
|
237 | |
|
|
238 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
239 | package and register them. Only handlers for eevents supported by the |
|
|
240 | object/class are recognised. |
|
|
241 | |
|
|
242 | =back |
|
|
243 | |
|
|
244 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
245 | event handler when a monster attacks: |
|
|
246 | |
|
|
247 | cf::object::attachment sockpuppet => |
|
|
248 | on_skill_attack => sub { |
|
|
249 | my ($self, $victim) = @_; |

|
448 | Just because you have a perl object does not mean that the corresponding |
|
|
449 | C-level object still exists. If you try to access an object that has no |
|
|
450 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
451 | can be used to test for existence of the C object part without causing an |
|
|
452 | exception. |

946 | =head2 EXTENSION DATABASE SUPPORT |
|
|
947 | |
|
|
948 | Crossfire maintains a very simple database for extension use. It can |
|
|
949 | currently store anything that can be serialised using Storable, which |
|
|
950 | excludes objects. |
|
|
951 | |
|
|
952 | The parameter C<$family> should best start with the name of the extension |
|
|
953 | using it, it should be unique. |
|
|
954 | |
|
|
955 | =over 4 |
|
|
956 | |
|
|
957 | =item $hashref = cf::db_get $family |
|
|
958 | |
|
|
959 | Return a hashref for use by the extension C<$family>, which can be |
|
|
960 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
961 | C<cf::db_sync>. |
|
|
962 | |
|
|
963 | =item $value = cf::db_get $family => $key |
|
|
964 | |
|
|
965 | Returns a single value from the database |
|
|
966 | |
|
|
967 | =item cf::db_put $family => $hashref |
|
|
968 | |
|
|
969 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
970 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
971 | |
|
|
972 | =item cf::db_put $family => $key => $value |
|
|
973 | |
|
|
974 | Stores the given C<$value> in the family hash. Updates are delayed, if you |
|
|
975 | want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
976 | |
|
|
977 | =item cf::db_dirty |
|
|
978 | |
|
|
979 | Marks the database as dirty, to be updated at a later time. |
|
|
980 | |
|
|
981 | =item cf::db_sync |
|
|
982 | |
|
|
983 | Immediately write the database to disk I<if it is dirty>. |
