|

155 | |
|
|
156 | The current CPU load on the server (alpha-smoothed), as a value between 0 |

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

649 | =head2 ATTACHABLE OBJECTS |
|
|
650 | |
|
|
651 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
652 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
653 | to it. All such attachable objects support the following methods. |
|
|
654 | |
|
|
655 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
656 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
657 | Crossfire TRT). |
|
|
658 | |
|
|
659 | =over 4 |
|
|
660 | |
|
|
661 | =item $attachable->attach ($attachment, key => $value...) |
|
|
662 | |
|
|
663 | =item $attachable->detach ($attachment) |
|
|
664 | |
|
|
665 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
666 | the specified key/value pairs as arguments. |
|
|
667 | |
|
|
668 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
669 | 10x10 minesweeper game: |
|
|
670 | |
|
|
671 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
672 | |
|
|
673 | =item $bool = $attachable->attached ($name) |
|
|
674 | |
|
|
675 | Checks wether the named attachment is currently attached to the object. |
|
|
676 | |
|
|
677 | =item cf::CLASS->attach ... |
|
|
678 | |
|
|
679 | =item cf::CLASS->detach ... |
|
|
680 | |
|
|
681 | Define an anonymous attachment and attach it to all objects of the given |
|
|
682 | CLASS. See the next function for an explanation of its arguments. |
|
|
683 | |
|
|
684 | You can attach to global events by using the C<cf::global> class. |
|
|
685 | |
|
|
686 | Example, log all player logins: |
|
|
687 | |
|
|
688 | cf::player->attach ( |
|
|
689 | on_login => sub { |
|
|
690 | my ($pl) = @_; |
|
|
691 | ... |
|
|
692 | }, |
|
|
693 | ); |
|
|
694 | |
|
|
695 | Example, attach to the jeweler skill: |
|
|
696 | |
|
|
697 | cf::object->attach ( |
|
|
698 | type => cf::SKILL, |
|
|
699 | subtype => cf::SK_JEWELER, |
|
|
700 | on_use_skill => sub { |
|
|
701 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
702 | ... |
|
|
703 | }, |
|
|
704 | ); |
|
|
705 | |
|
|
706 | =item cf::CLASS::attachment $name, ... |
|
|
707 | |
|
|
708 | Register an attachment by C<$name> through which attachable objects of the |
|
|
709 | given CLASS can refer to this attachment. |
|
|
710 | |
|
|
711 | Some classes such as crossfire maps and objects can specify attachments |
|
|
712 | that are attached at load/instantiate time, thus the need for a name. |
|
|
713 | |
|
|
714 | These calls expect any number of the following handler/hook descriptions: |
|
|
715 | |
|
|
716 | =over 4 |
|
|
717 | |
|
|
718 | =item prio => $number |
|
|
719 | |
|
|
720 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
721 | by another C<prio> setting). Lower priority handlers get executed |
|
|
722 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
723 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
724 | unless you know what you are doing. |
|
|
725 | |
|
|
726 | =item type => $type |
|
|
727 | |
|
|
728 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
729 | given type of objects only (the additional parameter C<subtype> can be |
|
|
730 | used to further limit to the given subtype). |
|
|
731 | |
|
|
732 | =item on_I<event> => \&cb |
|
|
733 | |
|
|
734 | Call the given code reference whenever the named event happens (event is |
|
|
735 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
736 | handlers are recognised generally depends on the type of object these |
|
|
737 | handlers attach to). |
|
|
738 | |
|
|
739 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
740 | class. |
|
|
741 | |
113 | package => package::, |
742 | =item package => package:: |
|
|
743 | |
|
|
744 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
745 | package and register them. Only handlers for eevents supported by the |
|
|
746 | object/class are recognised. |
|
|
747 | |

|
|
749 | |
|
|
750 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
751 | event handler when a monster attacks: |
|
|
752 | |
|
|
753 | cf::object::attachment sockpuppet => |
|
|
754 | on_skill_attack => sub { |
|
|
755 | my ($self, $victim) = @_; |
|
|
756 | ... |
|
|
757 | } |
|
|
758 | } |
|
|
759 | |
|
|
760 | =item $attachable->valid |
|
|
761 | |
|
|
762 | Just because you have a perl object does not mean that the corresponding |
|
|
763 | C-level object still exists. If you try to access an object that has no |
|
|
764 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
765 | can be used to test for existence of the C object part without causing an |
|
|
766 | exception. |
