The design of crossfire+ requires that the main coro ($Coro::main) is |
253 |
always able to handle events or runnable, as crossfire+ is only partly |
254 |
reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
255 |
|
256 |
If it must be done, put the blocking parts into C<sync_job>. This will run |
257 |
the given BLOCK in another coroutine while waiting for the result. The |
258 |
server will be frozen during this time, so the block should either finish |
259 |
fast or be very important. |

=head2 ATTACHABLE OBJECTS |
470 |
|
471 |
Many objects in crossfire are so-called attachable objects. That means you can |
472 |
attach callbacks/event handlers (a collection of which is called an "attachment") |
473 |
to it. All such attachable objects support the following methods. |
474 |
|
475 |
In the following description, CLASS can be any of C<global>, C<object> |
476 |
C<player>, C<client> or C<map> (i.e. the attachable objects in |
477 |
crossfire+). |
478 |
|
479 |
=over 4 |
480 |
|
481 |
=item $attachable->attach ($attachment, key => $value...) |
482 |
|
483 |
=item $attachable->detach ($attachment) |
484 |
|
485 |
Attach/detach a pre-registered attachment to a specific object and give it |
486 |
the specified key/value pairs as arguments. |
487 |
|
488 |
Example, attach a minesweeper attachment to the given object, making it a |
489 |
10x10 minesweeper game: |
490 |
|
491 |
$obj->attach (minesweeper => width => 10, height => 10); |
492 |
|
493 |
=item $bool = $attachable->attached ($name) |
494 |
|
495 |
Checks wether the named attachment is currently attached to the object. |
496 |
|
497 |
=item cf::CLASS->attach ... |
498 |
|
499 |
=item cf::CLASS->detach ... |
500 |
|
501 |
Define an anonymous attachment and attach it to all objects of the given |
502 |
CLASS. See the next function for an explanation of its arguments. |
503 |
|
504 |
You can attach to global events by using the C<cf::global> class. |
505 |
|
506 |
Example, log all player logins: |
507 |
|
508 |
cf::player->attach ( |
509 |
on_login => sub { |
510 |
my ($pl) = @_; |
511 |
... |
512 |
}, |
513 |
); |
514 |

Example, attach to the jeweler skill: |
516 |
|
517 |
cf::object->attach ( |
518 |
type => cf::SKILL, |
519 |
subtype => cf::SK_JEWELER, |
520 |
on_use_skill => sub { |
521 |
my ($sk, $ob, $part, $dir, $msg) = @_; |
522 |
... |
523 |
}, |
524 |
); |
525 |
|
526 |
=item cf::CLASS::attachment $name, ... |
527 |
|
528 |
Register an attachment by C<$name> through which attachable objects of the |
529 |
given CLASS can refer to this attachment. |
530 |
|
531 |
Some classes such as crossfire maps and objects can specify attachments |
532 |
that are attached at load/instantiate time, thus the need for a name. |
533 |
|
534 |
These calls expect any number of the following handler/hook descriptions: |
535 |
|
536 |
=over 4 |
537 |
|
538 |
=item prio => $number |
539 |
|
540 |
Set the priority for all following handlers/hooks (unless overwritten |
541 |
by another C<prio> setting). Lower priority handlers get executed |
542 |
earlier. The default priority is C<0>, and many built-in handlers are |
543 |
registered at priority C<-1000>, so lower priorities should not be used |
544 |
unless you know what you are doing. |
545 |
|
546 |
=item type => $type |
547 |
|
548 |
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
549 |
given type of objects only (the additional parameter C<subtype> can be |
550 |
used to further limit to the given subtype). |
551 |
|
552 |
=item on_I<event> => \&cb |
553 |
|
554 |
Call the given code reference whenever the named event happens (event is |
555 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
556 |
handlers are recognised generally depends on the type of object these |
557 |
handlers attach to). |
558 |
|
559 |
See F<include/eventinc.h> for the full list of events supported, and their |
560 |
class. |
561 |
|
562 |
=item package => package:: |
563 |
|
564 |
Look for sub functions of the name C<< on_I<event> >> in the given |
565 |
package and register them. Only handlers for eevents supported by the |
566 |
object/class are recognised. |
567 |
|
568 |
=back |
569 |
|
570 |
Example, define an attachment called "sockpuppet" that calls the given |
571 |
event handler when a monster attacks: |
572 |
|
573 |
cf::object::attachment sockpuppet => |
574 |
on_skill_attack => sub { |
575 |
my ($self, $victim) = @_; |
576 |
... |
577 |
} |
578 |
} |
579 |
|
580 |
=item $attachable->valid |
581 |
|
582 |
Just because you have a perl object does not mean that the corresponding |
583 |
C-level object still exists. If you try to access an object that has no |
584 |
valid C counterpart anymore you get an exception at runtime. This method |
585 |
can be used to test for existence of the C object part without causing an |
586 |
exception. |

1876 |
excludes objects. |
1877 |
