The design of Deliantra requires that the main coroutine ($Coro::main) |
456 |
|
|
is always able to handle events or runnable, as Deliantra is only |
457 |
root |
1.281 |
partly reentrant. Thus "blocking" it by e.g. waiting for I/O is not |
458 |
|
|
acceptable. |
459 |
root |
1.106 |

460 |

If it must be done, put the blocking parts into C<sync_job>. This will run |
461 |
|
|
the given BLOCK in another coroutine while waiting for the result. The |
462 |
|
|
server will be frozen during this time, so the block should either finish |
463 |
|
|
fast or be very important. |

726 |
|
|

727 |
root |
1.94 |
Many objects in crossfire are so-called attachable objects. That means you can |
728 |
|
|
attach callbacks/event handlers (a collection of which is called an "attachment") |
729 |
|
|
to it. All such attachable objects support the following methods. |
730 |
|
|
|
731 |
|
|
In the following description, CLASS can be any of C<global>, C<object> |
732 |
|
|
C<player>, C<client> or C<map> (i.e. the attachable objects in |
733 |
root |
1.394 |
Deliantra). |

=item $attachable->attach ($attachment, key => $value...) |
738 |
|
|
|
739 |
|
|
=item $attachable->detach ($attachment) |
740 |
|
|
|
741 |
|
|
Attach/detach a pre-registered attachment to a specific object and give it |
742 |
|
|
the specified key/value pairs as arguments. |
743 |
|
|
|
744 |
|
|
Example, attach a minesweeper attachment to the given object, making it a |
745 |
|
|
10x10 minesweeper game: |
746 |
root |
1.46 |
|
747 |
root |
1.94 |
$obj->attach (minesweeper => width => 10, height => 10); |

=item $bool = $attachable->attached ($name) |
750 |

Checks wether the named attachment is currently attached to the object. |

=item cf::CLASS->attach ... |

root |
1.94 |
=item cf::CLASS->detach ... |
756 |
root |
1.92 |
|
757 |
root |
1.94 |
Define an anonymous attachment and attach it to all objects of the given |
758 |
|
|
CLASS. See the next function for an explanation of its arguments. |
759 |
root |
1.92 |
|
760 |

1.93 |
You can attach to global events by using the C<cf::global> class. |
761 |
root |
1.92 |
|
762 |
root |
1.94 |
Example, log all player logins: |
763 |
|
|
|
764 |
|
|
cf::player->attach ( |
765 |
|
|
on_login => sub { |
766 |
|
|
my ($pl) = @_; |
767 |
|
|
... |
768 |
|
|
}, |
769 |
|
|
); |
770 |
|
|
|
771 |
|
|
Example, attach to the jeweler skill: |
772 |
|
|
|
773 |
|
|
cf::object->attach ( |
774 |
|
|
type => cf::SKILL, |
775 |
|
|
subtype => cf::SK_JEWELER, |
776 |
|
|
on_use_skill => sub { |
777 |
|
|
my ($sk, $ob, $part, $dir, $msg) = @_; |
778 |
|
|
... |
779 |
|
|
}, |
780 |
|
|
); |
781 |
|
|
|
782 |
|
|
=item cf::CLASS::attachment $name, ... |
783 |
|
|
|
784 |
|
|
Register an attachment by C<$name> through which attachable objects of the |
785 |
|
|
given CLASS can refer to this attachment. |
786 |
|
|
|
787 |
|
|
Some classes such as crossfire maps and objects can specify attachments |
788 |
|
|
that are attached at load/instantiate time, thus the need for a name. |
789 |
|
|
|
790 |
|
|
These calls expect any number of the following handler/hook descriptions: |
791 |

|
|
|
794 |
|
|
=item prio => $number |
795 |
|
|
|
796 |
|
|
Set the priority for all following handlers/hooks (unless overwritten |
797 |
|
|
by another C<prio> setting). Lower priority handlers get executed |
798 |
|
|
earlier. The default priority is C<0>, and many built-in handlers are |
799 |
|
|
registered at priority C<-1000>, so lower priorities should not be used |
800 |
|
|
unless you know what you are doing. |
801 |

|
|
802 |
root |
1.93 |
=item type => $type |
803 |
|
|
|
804 |
|
|
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
805 |
|
|
given type of objects only (the additional parameter C<subtype> can be |
806 |
|
|
used to further limit to the given subtype). |
807 |

|
808 |
root |
1.46 |
=item on_I<event> => \&cb |
809 |
|
|
|
810 |
|
|
Call the given code reference whenever the named event happens (event is |
811 |
|
|
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
812 |
|
|
handlers are recognised generally depends on the type of object these |
813 |
|
|
handlers attach to). |
814 |
|
|
|
815 |
|
|
See F<include/eventinc.h> for the full list of events supported, and their |
816 |
|
|
class. |

|
|
|
818 |
|
|
=item package => package:: |
819 |
|
|
|
820 |
|
|
Look for sub functions of the name C<< on_I<event> >> in the given |
821 |
|
|
package and register them. Only handlers for eevents supported by the |
822 |
|
|
object/class are recognised. |

Example, define an attachment called "sockpuppet" that calls the given |
827 |
|
|
event handler when a monster attacks: |
828 |
|
|
|
829 |
|
|
cf::object::attachment sockpuppet => |
830 |
|
|
on_skill_attack => sub { |
831 |
|
|
my ($self, $victim) = @_; |
832 |
|
|
... |
833 |
|
|
} |
834 |
|
|
} |

=item $attachable->valid |
837 |
|
|
|
838 |
|
|
Just because you have a perl object does not mean that the corresponding |
839 |
|
|
C-level object still exists. If you try to access an object that has no |
840 |
|
|
valid C counterpart anymore you get an exception at runtime. This method |
841 |
|
|
can be used to test for existence of the C object part without causing an |
842 |
|
|
exception. |
