144
145=over 4
146
147=item $cf::UPTIME
148
149The timestamp of the server start (so not actually an uptime).
150
151=item $cf::RUNTIME
152
153The time this server has run, starts at 0 and is increased by $cf::TICK on
154every server tick.
155
156=item $cf::CONFDIR $cf::DATADIR $cf::LIBDIR $cf::PODDIR
157$cf::MAPDIR $cf::LOCALDIR $cf::TMPDIR $cf::UNIQUEDIR
158$cf::PLAYERDIR $cf::RANDOMDIR $cf::BDBDIR
159
160Various directories - "/etc", read-only install directory, perl-library
161directory, pod-directory, read-only maps directory, "/var", "/var/tmp",
162unique-items directory, player file directory, random maps directory and
163database environment.
164
165=item $cf::NOW
166
167The time of the last (current) server tick.
168
169=item $cf::TICK
170
171The interval between server ticks, in seconds.
172
173=item $cf::LOADAVG
174
175The current CPU load on the server (alpha-smoothed), as a value between 0
176(none) and 1 (overloaded), indicating how much time is spent on processing
177objects per tick. Healthy values are < 0.5.
178
179=item $cf::LOAD
180
181The raw value load value from the last tick.
182
183=item %cf::CFG
184
185Configuration for the server, loaded from C</etc/deliantra-server/config>, or
186from wherever your confdir points to.
187
188=item cf::wait_for_tick, cf::wait_for_tick_begin
189
190These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only
191returns directly I<after> the tick processing (and consequently, can only wake one process
192per tick), while cf::wait_for_tick wakes up all waiters after tick processing.
193
194=item @cf::INVOKE_RESULTS
195
196This array contains the results of the last C<invoke ()> call. When
197C<cf::override> is called C<@cf::INVOKE_RESULTS> is set to the parameters of
198that call.

300
301=item cf::lock_wait $string
302
303Wait until the given lock is available. See cf::lock_acquire.
304
305=item my $lock = cf::lock_acquire $string
306
307Wait until the given lock is available and then acquires it and returns
308a Coro::guard object. If the guard object gets destroyed (goes out of scope,
309for example when the coroutine gets canceled), the lock is automatically
310returned.
311
312Locks are *not* recursive, locking from the same coro twice results in a
313deadlocked coro.
314
315Lock names should begin with a unique identifier (for example, cf::map::find
316uses map_find and cf::map::load uses map_load).
317

383}
384
385=item cf::get_slot $time[, $priority[, $name]]
386
387Allocate $time seconds of blocking CPU time at priority C<$priority>:
388This call blocks and returns only when you have at least C<$time> seconds
389of cpu time till the next tick. The slot is only valid till the next cede.
390
391The optional C<$name> can be used to identify the job to run. It might be
392used for statistical purposes and should identify the same time-class.
393
394Useful for short background jobs.

443=item cf::async { BLOCK }
444
445Currently the same as Coro::async_pool, meaning you cannot use
446C<on_destroy>, C<join> or other gimmicks on these coroutines. The only
447thing you are allowed to do is call C<prio> on it.

452
453=item cf::sync_job { BLOCK }
454
455The design of Deliantra requires that the main coroutine ($Coro::main)
456is always able to handle events or runnable, as Deliantra is only
457partly reentrant. Thus "blocking" it by e.g. waiting for I/O is not
458acceptable.
459
460If it must be done, put the blocking parts into C<sync_job>. This will run
461the given BLOCK in another coroutine while waiting for the result. The
462server will be frozen during this time, so the block should either finish
463fast or be very important.

725=head2 ATTACHABLE OBJECTS
726
727Many objects in crossfire are so-called attachable objects. That means you can
728attach callbacks/event handlers (a collection of which is called an "attachment")
729to it. All such attachable objects support the following methods.
730
731In the following description, CLASS can be any of C<global>, C<object>
732C<player>, C<client> or C<map> (i.e. the attachable objects in
733Deliantra).
734
735=over 4
736
737=item $attachable->attach ($attachment, key => $value...)
738
739=item $attachable->detach ($attachment)
740
741Attach/detach a pre-registered attachment to a specific object and give it
742the specified key/value pairs as arguments.
743
744Example, attach a minesweeper attachment to the given object, making it a
74510x10 minesweeper game:
746
747 $obj->attach (minesweeper => width => 10, height => 10);
748
749=item $bool = $attachable->attached ($name)
750
751Checks wether the named attachment is currently attached to the object.
752
753=item cf::CLASS->attach ...
754
755=item cf::CLASS->detach ...
756
757Define an anonymous attachment and attach it to all objects of the given
758CLASS. See the next function for an explanation of its arguments.
759
760You can attach to global events by using the C<cf::global> class.
761
762Example, log all player logins:
763
764 cf::player->attach (
765 on_login => sub {
766 my ($pl) = @_;
767 ...
768 },
769 );
770
771Example, attach to the jeweler skill:
772
773 cf::object->attach (
774 type => cf::SKILL,
775 subtype => cf::SK_JEWELER,
776 on_use_skill => sub {
777 my ($sk, $ob, $part, $dir, $msg) = @_;
778 ...
779 },
780 );
781
782=item cf::CLASS::attachment $name, ...
783
784Register an attachment by C<$name> through which attachable objects of the
785given CLASS can refer to this attachment.
786
787Some classes such as crossfire maps and objects can specify attachments
788that are attached at load/instantiate time, thus the need for a name.
789
790These calls expect any number of the following handler/hook descriptions:
791
792=over 4
793
794=item prio => $number
795
796Set the priority for all following handlers/hooks (unless overwritten
797by another C<prio> setting). Lower priority handlers get executed
798earlier. The default priority is C<0>, and many built-in handlers are
799registered at priority C<-1000>, so lower priorities should not be used
800unless you know what you are doing.
801
802=item type => $type
803
804(Only for C<< cf::object->attach >> calls), limits the attachment to the
805given type of objects only (the additional parameter C<subtype> can be
806used to further limit to the given subtype).
807
808=item on_I<event> => \&cb
809
810Call the given code reference whenever the named event happens (event is
811something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
812handlers are recognised generally depends on the type of object these
813handlers attach to).
814
815See F<include/eventinc.h> for the full list of events supported, and their
816class.
817
818=item package => package::
819
820Look for sub functions of the name C<< on_I<event> >> in the given
821package and register them. Only handlers for eevents supported by the
822object/class are recognised.
823
824=back
825
826Example, define an attachment called "sockpuppet" that calls the given
827event handler when a monster attacks:
828
829 cf::object::attachment sockpuppet =>
830 on_skill_attack => sub {
831 my ($self, $victim) = @_;
832 ...
833 }
834 }
835
836=item $attachable->valid
837
838Just because you have a perl object does not mean that the corresponding
839C-level object still exists. If you try to access an object that has no
840valid C counterpart anymore you get an exception at runtime. This method
841can be used to test for existence of the C object part without causing an
842exception.

1241
1242Register a callback for execution when the client sends an (asynchronous)
1243exticmd packet. Exti commands are processed by the server as soon as they
1244are received, i.e. out of order w.r.t. other commands. The first argument
1245is a client socket. Exti commands can be received anytime, even before
1246log-in.
1247
1248If the callback returns something, it is sent back as if reply was being
1249called.
