The design of crossfire+ requires that the main coro ($Coro::main) is |
189 |
always able to handle events or runnable, as crossfire+ is only partly |
190 |
reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
191 |
|
192 |
If it must be done, put the blocking parts into C<sync_job>. This will run |
193 |
the given BLOCK in another coroutine while waiting for the result. The |
194 |
server will be frozen during this time, so the block should either finish |
195 |
fast or be very important. |

=head2 ATTACHABLE OBJECTS |
396 |
|
397 |
Many objects in crossfire are so-called attachable objects. That means you can |
398 |
attach callbacks/event handlers (a collection of which is called an "attachment") |
399 |
to it. All such attachable objects support the following methods. |
400 |
|
401 |
In the following description, CLASS can be any of C<global>, C<object> |
402 |
C<player>, C<client> or C<map> (i.e. the attachable objects in |
403 |
crossfire+). |
404 |
|
405 |
=over 4 |
406 |
|
407 |
=item $attachable->attach ($attachment, key => $value...) |
408 |
|
409 |
=item $attachable->detach ($attachment) |
410 |
|
411 |
Attach/detach a pre-registered attachment to a specific object and give it |
412 |
the specified key/value pairs as arguments. |
413 |
|
414 |
Example, attach a minesweeper attachment to the given object, making it a |
415 |
10x10 minesweeper game: |
416 |
|
417 |
$obj->attach (minesweeper => width => 10, height => 10); |
418 |
|
419 |
=item $bool = $attachable->attached ($name) |
420 |
|
421 |
Checks wether the named attachment is currently attached to the object. |
422 |
|
423 |
=item cf::CLASS->attach ... |
424 |
|
425 |
=item cf::CLASS->detach ... |
426 |
|
427 |
Define an anonymous attachment and attach it to all objects of the given |
428 |
CLASS. See the next function for an explanation of its arguments. |
429 |
|
430 |
You can attach to global events by using the C<cf::global> class. |
431 |
|
432 |
Example, log all player logins: |
433 |
|
434 |
cf::player->attach ( |
435 |
on_login => sub { |
436 |
my ($pl) = @_; |
437 |
... |
438 |
}, |
439 |
); |
440 |
|
441 |
Example, attach to the jeweler skill: |
442 |
|
443 |
cf::object->attach ( |
444 |
type => cf::SKILL, |
445 |
subtype => cf::SK_JEWELER, |
446 |
on_use_skill => sub { |
447 |
my ($sk, $ob, $part, $dir, $msg) = @_; |
448 |
... |
449 |
}, |
450 |
); |
451 |
|
452 |
=item cf::CLASS::attachment $name, ... |
453 |
|
454 |
Register an attachment by C<$name> through which attachable objects of the |
455 |
given CLASS can refer to this attachment. |
456 |
|
457 |
Some classes such as crossfire maps and objects can specify attachments |
458 |
that are attached at load/instantiate time, thus the need for a name. |
459 |
|
460 |
These calls expect any number of the following handler/hook descriptions: |
461 |
|
462 |
=over 4 |
463 |
|
464 |
=item prio => $number |
465 |
|
466 |
Set the priority for all following handlers/hooks (unless overwritten |
467 |
by another C<prio> setting). Lower priority handlers get executed |
468 |
earlier. The default priority is C<0>, and many built-in handlers are |
469 |
registered at priority C<-1000>, so lower priorities should not be used |
470 |
unless you know what you are doing. |
471 |
|
472 |
=item type => $type |
473 |
|
474 |
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
475 |
given type of objects only (the additional parameter C<subtype> can be |
476 |
used to further limit to the given subtype). |
477 |
|
478 |
=item on_I<event> => \&cb |
479 |
|
480 |
Call the given code reference whenever the named event happens (event is |
481 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
482 |
handlers are recognised generally depends on the type of object these |
483 |
handlers attach to). |
484 |
|
485 |
See F<include/eventinc.h> for the full list of events supported, and their |
486 |
class. |
487 |
|
488 |
=item package => package:: |
489 |
|
490 |
Look for sub functions of the name C<< on_I<event> >> in the given |
491 |
package and register them. Only handlers for eevents supported by the |
492 |
object/class are recognised. |
493 |
|
494 |
=back |
495 |
|
496 |
Example, define an attachment called "sockpuppet" that calls the given |
497 |
event handler when a monster attacks: |
498 |
|
499 |
cf::object::attachment sockpuppet => |
500 |
on_skill_attack => sub { |
501 |
my ($self, $victim) = @_; |
502 |
... |
503 |
} |
504 |
} |
505 |
|
506 |
=item $attachable->valid |
507 |
|
508 |
Just because you have a perl object does not mean that the corresponding |
509 |
C-level object still exists. If you try to access an object that has no |
510 |
valid C counterpart anymore you get an exception at runtime. This method |
511 |
can be used to test for existence of the C object part without causing an |
512 |
exception. |
