C<on_destroy>, C<join> or other gimmicks on these coroutines. The only |

The design of crossfire+ requires that the main coro ($Coro::main) is |
280 |
|
|
always able to handle events or runnable, as crossfire+ is only partly |
281 |
|
|
reentrant. Thus "blocking" it by e.g. waiting for I/O is not acceptable. |
282 |
|
|
|
283 |
|
|
If it must be done, put the blocking parts into C<sync_job>. This will run |
284 |
|
|
the given BLOCK in another coroutine while waiting for the result. The |
285 |
|
|
server will be frozen during this time, so the block should either finish |
286 |
|
|
fast or be very important. |

Many objects in crossfire are so-called attachable objects. That means you can |
375 |
|
|
attach callbacks/event handlers (a collection of which is called an "attachment") |
376 |
|
|
to it. All such attachable objects support the following methods. |
377 |
|
|
|
378 |
|
|
In the following description, CLASS can be any of C<global>, C<object> |
379 |
|
|
C<player>, C<client> or C<map> (i.e. the attachable objects in |
380 |
|
|
crossfire+). |

=item $attachable->attach ($attachment, key => $value...) |
385 |
|
|
|
386 |
|
|
=item $attachable->detach ($attachment) |
387 |
|
|
|
388 |
|
|
Attach/detach a pre-registered attachment to a specific object and give it |
389 |
|
|
the specified key/value pairs as arguments. |
390 |
|
|
|
391 |
|
|
Example, attach a minesweeper attachment to the given object, making it a |
392 |
|
|
10x10 minesweeper game: |
393 |
root |
1.46 |
|
394 |
root |
1.94 |
$obj->attach (minesweeper => width => 10, height => 10); |

Define an anonymous attachment and attach it to all objects of the given |
405 |
|
|
CLASS. See the next function for an explanation of its arguments. |
406 |

1.92 |
|
407 |

You can attach to global events by using the C<cf::global> class. |
408 |
root |
1.92 |
|
409 |

Example, log all player logins: |
410 |
|
|
|
411 |
|
|
cf::player->attach ( |
412 |
|
|
on_login => sub { |
413 |
|
|
my ($pl) = @_; |
414 |
|
|
... |
415 |
|
|
}, |
416 |
|
|
); |
417 |
|
|
|
418 |
|
|
Example, attach to the jeweler skill: |
419 |
|
|
|
420 |
|
|
cf::object->attach ( |
421 |
|
|
type => cf::SKILL, |
422 |
|
|
subtype => cf::SK_JEWELER, |
423 |
|
|
on_use_skill => sub { |
424 |
|
|
my ($sk, $ob, $part, $dir, $msg) = @_; |
425 |
|
|
... |
426 |
|
|
}, |
427 |
|
|
); |
428 |
|
|
|
429 |
|
|
=item cf::CLASS::attachment $name, ... |
430 |
|
|
|
431 |
|
|
Register an attachment by C<$name> through which attachable objects of the |
432 |
|
|
given CLASS can refer to this attachment. |
433 |
|
|
|
434 |
|
|
Some classes such as crossfire maps and objects can specify attachments |
435 |
|
|
that are attached at load/instantiate time, thus the need for a name. |
436 |
|
|
|
437 |
|
|
These calls expect any number of the following handler/hook descriptions: |
438 |

|
|
|
441 |
|
|
=item prio => $number |
442 |
|
|
|
443 |
|
|
Set the priority for all following handlers/hooks (unless overwritten |
444 |
|
|
by another C<prio> setting). Lower priority handlers get executed |
445 |
|
|
earlier. The default priority is C<0>, and many built-in handlers are |
446 |
|
|
registered at priority C<-1000>, so lower priorities should not be used |
447 |
|
|
unless you know what you are doing. |
448 |

449 |
root |
1.93 |
=item type => $type |
450 |
|
|
|
451 |
|
|
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
452 |
|
|
given type of objects only (the additional parameter C<subtype> can be |
453 |
|
|
used to further limit to the given subtype). |
454 |

|
455 |
root |
1.46 |
=item on_I<event> => \&cb |
456 |
|
|
|
457 |
|
|
Call the given code reference whenever the named event happens (event is |
458 |
|
|
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
459 |
|
|
handlers are recognised generally depends on the type of object these |
460 |
|
|
handlers attach to). |
461 |
|
|
|
462 |
|
|
See F<include/eventinc.h> for the full list of events supported, and their |
463 |
|
|
class. |

|
|
|
465 |
|
|
=item package => package:: |
466 |
|
|
|
467 |
|
|
Look for sub functions of the name C<< on_I<event> >> in the given |
468 |
|
|
package and register them. Only handlers for eevents supported by the |
469 |
|
|
object/class are recognised. |

Example, define an attachment called "sockpuppet" that calls the given |
474 |
|
|
event handler when a monster attacks: |
475 |
|
|
|
476 |
|
|
cf::object::attachment sockpuppet => |
477 |
|
|
on_skill_attack => sub { |
478 |
|
|
my ($self, $victim) = @_; |
479 |
|
|
... |
480 |
|
|
} |
481 |
|
|
} |

=item $attachable->valid |
484 |
|
|
|
485 |
|
|
Just because you have a perl object does not mean that the corresponding |
486 |
|
|
C-level object still exists. If you try to access an object that has no |
487 |
|
|
valid C counterpart anymore you get an exception at runtime. This method |
488 |
|
|
can be used to test for existence of the C object part without causing an |
489 |
|
|
exception. |

|
Crossfire maintains a very simple database for extension use. It can |
2086 |
|
|
currently store anything that can be serialised using Storable, which |
2087 |
|
|
excludes objects. |
2088 |
|
|
|
2089 |
|
|
The parameter C<$family> should best start with the name of the extension |
2090 |
|
|
using it, it should be unique. |

|
2096 |
|
|
Return a hashref for use by the extension C<$family>, which can be |
2097 |
|
|
modified. After modifications, you have to call C<cf::db_dirty> or |
2098 |
|
|
C<cf::db_sync>. |

2100 |
|

|
2104 |
|
|
=item cf::db_put $family => $hashref |
2105 |

|
|
Stores the given family hashref into the database. Updates are delayed, if |
2107 |
|
|
you want the data to be synced to disk immediately, use C<cf::db_sync>. |

2109 |
