191 | the given BLOCK in another coroutine while waiting for the result. The |

381 | =head2 ATTACHABLE OBJECTS |
115 | |
382 | |
116 | =item cf::attach_global ... |
383 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
384 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
385 | to it. All such attachable objects support the following methods. |
117 | |
386 | |
118 | =item cf::attach_to_type ... |
387 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
388 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
389 | crossfire+). |
119 | |
390 | |
120 | =item cf::attach_to_objects ... |
391 | =over 4 |
121 | |
392 | |
122 | =item cf::attach_to_players ... |
393 | =item $attachable->attach ($attachment, key => $value...) |
123 | |
394 | |
124 | =item cf::attach_to_maps ... |
395 | =item $attachable->detach ($attachment) |
125 | |
396 | |
126 | prio => $number, # lower is earlier |
397 | Attach/detach a pre-registered attachment to a specific object and give it |
127 | on_xxx => \&cb, |
398 | the specified key/value pairs as arguments. |
|
|
399 | |
|
|
400 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
401 | 10x10 minesweeper game: |
|
|
402 | |
|
|
403 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
404 | |
|
|
405 | =item $bool = $attachable->attached ($name) |
|
|
406 | |
|
|
407 | Checks wether the named attachment is currently attached to the object. |
|
|
408 | |
|
|
409 | =item cf::CLASS->attach ... |
|
|
410 | |
|
|
411 | =item cf::CLASS->detach ... |
|
|
412 | |
|
|
413 | Define an anonymous attachment and attach it to all objects of the given |
|
|
414 | CLASS. See the next function for an explanation of its arguments. |
|
|
415 | |
|
|
416 | You can attach to global events by using the C<cf::global> class. |
|
|
417 | |
|
|
418 | Example, log all player logins: |
|
|
419 | |
|
|
420 | cf::player->attach ( |
|
|
421 | on_login => sub { |
|
|
422 | my ($pl) = @_; |
|
|
423 | ... |
|
|
424 | }, |
|
|
425 | ); |
|
|
426 | |
|
|
427 | Example, attach to the jeweler skill: |
|
|
428 | |
|
|
429 | cf::object->attach ( |
|
|
430 | type => cf::SKILL, |
|
|
431 | subtype => cf::SK_JEWELER, |
|
|
432 | on_use_skill => sub { |
|
|
433 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
434 | ... |
|
|
435 | }, |
|
|
436 | ); |
|
|
437 | |
|
|
438 | =item cf::CLASS::attachment $name, ... |
|
|
439 | |
|
|
440 | Register an attachment by C<$name> through which attachable objects of the |
|
|
441 | given CLASS can refer to this attachment. |
|
|
442 | |
|
|
443 | Some classes such as crossfire maps and objects can specify attachments |
|
|
444 | that are attached at load/instantiate time, thus the need for a name. |
|
|
445 | |
|
|
446 | These calls expect any number of the following handler/hook descriptions: |
|
|
447 | |
|
|
448 | =over 4 |
|
|
449 | |
|
|
450 | =item prio => $number |
|
|
451 | |
|
|
452 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
453 | by another C<prio> setting). Lower priority handlers get executed |
|
|
454 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
455 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
456 | unless you know what you are doing. |
|
|
457 | |
|
|
458 | =item type => $type |
|
|
459 | |
|
|
460 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
461 | given type of objects only (the additional parameter C<subtype> can be |
|
|
462 | used to further limit to the given subtype). |
|
|
463 | |
|
|
464 | =item on_I<event> => \&cb |
|
|
465 | |
|
|
466 | Call the given code reference whenever the named event happens (event is |
|
|
467 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
468 | handlers are recognised generally depends on the type of object these |
|
|
469 | handlers attach to). |
|
|
470 | |
|
|
471 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
472 | class. |
|
|
473 | |
128 | package => package::, |
474 | =item package => package:: |
|
|
475 | |
|
|
476 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
477 | package and register them. Only handlers for eevents supported by the |
|
|
478 | object/class are recognised. |
|
|
479 | |
|
|
480 | =back |
|
|
481 | |
|
|
482 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
483 | event handler when a monster attacks: |
|
|
484 | |
|
|
485 | cf::object::attachment sockpuppet => |
|
|
486 | on_skill_attack => sub { |
|
|
487 | my ($self, $victim) = @_; |
|
|
488 | ... |
|
|
489 | } |
|
|
490 | } |
|
|
491 | |
|
|
492 | =item $attachable->valid |
|
|
493 | |
|
|
494 | Just because you have a perl object does not mean that the corresponding |
|
|
495 | C-level object still exists. If you try to access an object that has no |
|
|
496 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
497 | can be used to test for existence of the C object part without causing an |
|
|
498 | exception. |

1292 | =head2 EXTENSION DATABASE SUPPORT |
|
|
1293 | |
|
|
1294 | Crossfire maintains a very simple database for extension use. It can |
|
|
1295 | currently store anything that can be serialised using Storable, which |
|
|
1296 | excludes objects. |
|
|
1297 | |
|
|
1298 | The parameter C<$family> should best start with the name of the extension |
|
|
1299 | using it, it should be unique. |
|

|
|
1302 | |
|
|
1303 | =item $hashref = cf::db_get $family |
|
|
1304 | |
|
|
1305 | Return a hashref for use by the extension C<$family>, which can be |
|
|
1306 | modified. After modifications, you have to call C<cf::db_dirty> or |
|
|
1307 | C<cf::db_sync>. |
|
|
1308 | |
|
|
1309 | =item $value = cf::db_get $family => $key |

|

1312 | |
|
|
1313 | =item cf::db_put $family => $hashref |
|
|
1314 | |
|
|
1315 | Stores the given family hashref into the database. Updates are delayed, if |
|
|
1316 | you want the data to be synced to disk immediately, use C<cf::db_sync>. |
|
|
1317 | |
|
|
1318 | =item cf::db_put $family => $key => $value |
|

1319 | |

|
1322 | |
|
