172 | |
|

173 | =item $cf::LOADAVG |
|

174 | |
|
|

727 | =head2 ATTACHABLE OBJECTS |
|
|
728 | |
|
|
729 | Many objects in crossfire are so-called attachable objects. That means you can |
|
|
730 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
731 | to it. All such attachable objects support the following methods. |
|
|
732 | |
|
|
733 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
734 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
735 | Deliantra). |
|
|
736 | |
|
|
737 | =over 4 |
|
|
738 | |
|
|
739 | =item $attachable->attach ($attachment, key => $value...) |
|
|
740 | |
|
|
741 | =item $attachable->detach ($attachment) |
|
|
742 | |
|
|
743 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
744 | the specified key/value pairs as arguments. |
|
|
745 | |
|
|
746 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
747 | 10x10 minesweeper game: |
|
|
748 | |
|
|
749 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
750 | |
|
|
751 | =item $bool = $attachable->attached ($name) |
|
|
752 | |
|
|
753 | Checks wether the named attachment is currently attached to the object. |
|
|
754 | |
|
|
755 | =item cf::CLASS->attach ... |
|
|
756 | |
|
|
757 | =item cf::CLASS->detach ... |
|
|
758 | |
|
|
759 | Define an anonymous attachment and attach it to all objects of the given |
|
|
760 | CLASS. See the next function for an explanation of its arguments. |
|
|
761 | |
|
|
762 | You can attach to global events by using the C<cf::global> class. |
|
|
763 | |
|
|
764 | Example, log all player logins: |
|
|
765 | |
|
|
766 | cf::player->attach ( |
|
|
767 | on_login => sub { |
|
|
768 | my ($pl) = @_; |
|
|
769 | ... |
|
|
770 | }, |
|
|
771 | ); |
|
|
772 | |
|
|
773 | Example, attach to the jeweler skill: |
|
|
774 | |
|
|
775 | cf::object->attach ( |
|
|
776 | type => cf::SKILL, |
|
|
777 | subtype => cf::SK_JEWELER, |
|
|
778 | on_use_skill => sub { |
|
|
779 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
780 | ... |
|
|
781 | }, |
|
|
782 | ); |
|
|
783 | |
|
|
784 | =item cf::CLASS::attachment $name, ... |
|
|
785 | |
|
|
786 | Register an attachment by C<$name> through which attachable objects of the |
|
|
787 | given CLASS can refer to this attachment. |
|
|
788 | |
|
|
789 | Some classes such as crossfire maps and objects can specify attachments |
|
|
790 | that are attached at load/instantiate time, thus the need for a name. |
|
|
791 | |
|
|
792 | These calls expect any number of the following handler/hook descriptions: |
|
|
793 | |
|
|
794 | =over 4 |
|
|
795 | |
|
|
796 | =item prio => $number |
|
|
797 | |
|
|
798 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
799 | by another C<prio> setting). Lower priority handlers get executed |
|
|
800 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
801 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
802 | unless you know what you are doing. |
|
|
803 | |
|
|
804 | =item type => $type |
|
|
805 | |
|
|
806 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
807 | given type of objects only (the additional parameter C<subtype> can be |
|
|
808 | used to further limit to the given subtype). |
|
|
809 | |
|
|
810 | =item on_I<event> => \&cb |
|
|
811 | |
|
|
812 | Call the given code reference whenever the named event happens (event is |
|
|
813 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
814 | handlers are recognised generally depends on the type of object these |
|
|
815 | handlers attach to). |
|
|
816 | |
|
|
817 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
818 | class. |
|
|
819 | |
|
|
820 | =item package => package:: |
|
|
821 | |
|
|
822 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
823 | package and register them. Only handlers for eevents supported by the |
|
|
824 | object/class are recognised. |
|
|
825 | |
|
|
826 | =back |
|
|
827 | |
|
|
828 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
829 | event handler when a monster attacks: |
|
|
830 | |
|
|
831 | cf::object::attachment sockpuppet => |
|
|
832 | on_skill_attack => sub { |
|
|
833 | my ($self, $victim) = @_; |
|
|
834 | ... |
|
|
835 | } |
|
|
836 | } |
|
|
837 | |
|
|
838 | =item $attachable->valid |
|
|
839 | |
|
|
840 | Just because you have a perl object does not mean that the corresponding |
|
|
841 | C-level object still exists. If you try to access an object that has no |
|
|
842 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
843 | can be used to test for existence of the C object part without causing an |
|
|
844 | exception. |
