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

533 | =head2 ATTACHABLE OBJECTS |
|
|
534 | |
|
|
535 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
536 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
537 | to it. All such attachable objects support the following methods. |
|
|
538 | |
|
|
539 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
540 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
541 | crossfire+). |
|
|
542 | |
|
|
543 | =over 4 |
|
|
544 | |
110 | =item $object->attach ($attachment, key => $value...) |
545 | =item $attachable->attach ($attachment, key => $value...) |
111 | |
546 | |
112 | Attach a pre-registered attachment to an object. |
547 | =item $attachable->detach ($attachment) |
113 | |
548 | |
114 | =item $player->attach ($attachment, key => $value...) |
549 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
550 | the specified key/value pairs as arguments. |
115 | |
551 | |
116 | Attach a pre-registered attachment to a player. |
552 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
553 | 10x10 minesweeper game: |
117 | |
554 | |
118 | =item $map->attach ($attachment, key => $value...) # not yet persistent |
555 | $obj->attach (minesweeper => width => 10, height => 10); |
119 | |
556 | |
120 | Attach a pre-registered attachment to a map. |
557 | =item $bool = $attachable->attached ($name) |
121 | |
558 | |
122 | =item cf::attach_global ... |
559 | Checks wether the named attachment is currently attached to the object. |
123 | |
560 | |
124 | Attach handlers for global events. |
561 | =item cf::CLASS->attach ... |
125 | |
562 | |
126 | This and all following C<attach_*>-functions expect any number of the |
563 | =item cf::CLASS->detach ... |
127 | following handler/hook descriptions: |
564 | |
|
|
565 | Define an anonymous attachment and attach it to all objects of the given |
|
|
566 | CLASS. See the next function for an explanation of its arguments. |
|
|
567 | |
|
|
568 | You can attach to global events by using the C<cf::global> class. |
|
|
569 | |
|
|
570 | Example, log all player logins: |
|
|
571 | |
|
|
572 | cf::player->attach ( |
|
|
573 | on_login => sub { |
|
|
574 | my ($pl) = @_; |
|
|
575 | ... |
|
|
576 | }, |
|
|
577 | ); |
|
|
578 | |
|
|
579 | Example, attach to the jeweler skill: |
|
|
580 | |
|
|
581 | cf::object->attach ( |
|
|
582 | type => cf::SKILL, |
|
|
583 | subtype => cf::SK_JEWELER, |
|
|
584 | on_use_skill => sub { |
|
|
585 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
586 | ... |
|
|
587 | }, |
|
|
588 | ); |
|
|
589 | |
|
|
590 | =item cf::CLASS::attachment $name, ... |
|
|
591 | |
|
|
592 | Register an attachment by C<$name> through which attachable objects of the |
|
|
593 | given CLASS can refer to this attachment. |
|
|
594 | |
|
|
595 | Some classes such as crossfire maps and objects can specify attachments |
|
|
596 | that are attached at load/instantiate time, thus the need for a name. |
|
|
597 | |
|
|
598 | These calls expect any number of the following handler/hook descriptions: |
128 | |

605 | by another C<prio> setting). Lower priority handlers get executed |
135 | earlier. The default priority is C<0>, and many built-in handlers are |
606 | earlier. The default priority is C<0>, and many built-in handlers are |
136 | registered at priority C<-1000>, so lower priorities should not be used |
607 | registered at priority C<-1000>, so lower priorities should not be used |

|
613 | given type of objects only (the additional parameter C<subtype> can be |
|

614 | used to further limit to the given subtype). |

|
|
635 | event handler when a monster attacks: |
158 | |
636 | |
159 | Attach handlers for a specific object type (e.g. TRANSPORT) and |
