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

492 | =head2 ATTACHABLE OBJECTS |
|
|
493 | |
|
|
494 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
495 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
496 | to it. All such attachable objects support the following methods. |
|
|
497 | |
|
|
498 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
499 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
500 | crossfire+). |
|
|
501 | |
|
|
502 | =over 4 |
|
|
503 | |
|
|
504 | =item $attachable->attach ($attachment, key => $value...) |
|
|
505 | |
|
|
506 | =item $attachable->detach ($attachment) |
|
|
507 | |
|
|
508 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
509 | the specified key/value pairs as arguments. |
|
|
510 | |
|
|
511 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
512 | 10x10 minesweeper game: |
|
|
513 | |
|
|
514 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
515 | |
|
|
516 | =item $bool = $attachable->attached ($name) |
|
|
517 | |
|
|
518 | Checks wether the named attachment is currently attached to the object. |
|
|
519 | |
|
|
520 | =item cf::CLASS->attach ... |
|
|
521 | |
|
|
522 | =item cf::CLASS->detach ... |
|
|
523 | |
|
|
524 | Define an anonymous attachment and attach it to all objects of the given |
|
|
525 | CLASS. See the next function for an explanation of its arguments. |
|
|
526 | |
|
|
527 | You can attach to global events by using the C<cf::global> class. |
|
|
528 | |
|
|
529 | Example, log all player logins: |
|
|
530 | |
|
|
531 | cf::player->attach ( |
|
|
532 | on_login => sub { |
|
|
533 | my ($pl) = @_; |
|
|
534 | ... |
|
|
535 | }, |
|
|
536 | ); |
|
|
537 | |
|
|
538 | Example, attach to the jeweler skill: |
|
|
539 | |
|
|
540 | cf::object->attach ( |
|
|
541 | type => cf::SKILL, |
|
|
542 | subtype => cf::SK_JEWELER, |
|
|
543 | on_use_skill => sub { |
|
|
544 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
545 | ... |
|
|
546 | }, |
|
|
547 | ); |
|
|
548 | |
|
|
549 | =item cf::CLASS::attachment $name, ... |
|
|
550 | |
|
|
551 | Register an attachment by C<$name> through which attachable objects of the |
|
|
552 | given CLASS can refer to this attachment. |
|
|
553 | |
|
|
554 | Some classes such as crossfire maps and objects can specify attachments |
|
|
555 | that are attached at load/instantiate time, thus the need for a name. |
|
|
556 | |
|
|
557 | These calls expect any number of the following handler/hook descriptions: |
|
|
558 | |
|
|
559 | =over 4 |
|
|
560 | |
|
|
561 | =item prio => $number |
|
|
562 | |
|
|
563 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
564 | by another C<prio> setting). Lower priority handlers get executed |
|
|
565 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
566 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
567 | unless you know what you are doing. |
|
|
568 | |
|
|
569 | =item type => $type |
|
|
570 | |
|
|
571 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
572 | given type of objects only (the additional parameter C<subtype> can be |
|
|
573 | used to further limit to the given subtype). |
|
|
574 | |
|
|
575 | =item on_I<event> => \&cb |
|
|
576 | |
|
|
577 | Call the given code reference whenever the named event happens (event is |
|
|
578 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
579 | handlers are recognised generally depends on the type of object these |
|
|
580 | handlers attach to). |
|
|
581 | |
|
|
582 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
583 | class. |
|
|
584 | |
|
|
585 | =item package => package:: |
|
|
586 | |
|
|
587 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
588 | package and register them. Only handlers for eevents supported by the |
|
|
589 | object/class are recognised. |
|
|
590 | |
|
|
591 | =back |
|
|
592 | |
|
|
593 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
594 | event handler when a monster attacks: |
|
|
595 | |
|
|
596 | cf::object::attachment sockpuppet => |
|
|
597 | on_skill_attack => sub { |
|
|
598 | my ($self, $victim) = @_; |
|
|
599 | ... |
|
|
600 | } |
|
|
601 | } |
|
|
602 | |
|
|
603 | =item $attachable->valid |
|
|
604 | |
|
|
605 | Just because you have a perl object does not mean that the corresponding |
|
|
606 | C-level object still exists. If you try to access an object that has no |
|
|
607 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
608 | can be used to test for existence of the C object part without causing an |
|
|
609 | exception. |
