211
212The current CPU load on the server (alpha-smoothed), as a value between 0

227These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only
228returns directly I<after> the tick processing (and consequently, can only wake one process
229per tick), while cf::wait_for_tick wakes up all waiters after tick processing.

232
233This array contains the results of the last C<invoke ()> call. When
234C<cf::override> is called C<@cf::INVOKE_RESULTS> is set to the parameters of
235that call.

239Contains, for each (C++) class name, a hash reference with information
240about object members (methods, scalars, arrays and flags) and other

357Wait until the given lock is available. See cf::lock_acquire.
358
359=item my $lock = cf::lock_acquire $string
360
361Wait until the given lock is available and then acquires it and returns
362a L<Guard> object. If the guard object gets destroyed (goes out of scope,
363for example when the coroutine gets canceled), the lock is automatically
364returned.
365
366Locks are *not* recursive, locking from the same coro twice results in a
367deadlocked coro.
368
369Lock names should begin with a unique identifier (for example, cf::map::find
370uses map_find and cf::map::load uses map_load).
371

416This call blocks and returns only when you have at least C<$time> seconds
417of cpu time till the next tick. The slot is only valid till the next cede.
418
419The optional C<$name> can be used to identify the job to run. It might be
420used for statistical purposes and should identify the same time-class.

474
475Currently the same as Coro::async_pool, meaning you cannot use
476C<on_destroy>, C<join> or other gimmicks on these coroutines. The only
477thing you are allowed to do is call C<prio> on it.

484
485The design of Deliantra requires that the main coroutine ($Coro::main)
486is always able to handle events or runnable, as Deliantra is only
487partly reentrant. Thus "blocking" it by e.g. waiting for I/O is not
488acceptable.
489
490If it must be done, put the blocking parts into C<sync_job>. This will run
491the given BLOCK in another coroutine while waiting for the result. The
492server will be frozen during this time, so the block should either finish
493fast or be very important.

130=head2 EVENTS AND OBJECT ATTACHMENTS 755=head2 ATTACHABLE OBJECTS
756
757Many objects in deliantra are so-called attachable objects. That means you can
758attach callbacks/event handlers (a collection of which is called an "attachment")
759to it. All such attachable objects support the following methods.
760
761In the following description, CLASS can be any of C<global>, C<object>
762C<player>, C<client> or C<map> (i.e. the attachable objects in
763Deliantra).

139
140=item $player->attach ($attachment, key => $value...)

150Attach/detach a pre-registered attachment to a map. 771Attach/detach a pre-registered attachment to a specific object and give it
772the specified key/value pairs as arguments.
151 773
152=item $bool = $object->attached ($name) 774Example, attach a minesweeper attachment to the given object, making it a
77510x10 minesweeper game:
153 776
154=item $bool = $player->attached ($name) 777 $obj->attach (minesweeper => width => 10, height => 10);

165following handler/hook descriptions: 788CLASS. See the next function for an explanation of its arguments.
789
790You can attach to global events by using the C<cf::global> class.
791
792Example, log all player logins:
793
794 cf::player->attach (
795 on_login => sub {
796 my ($pl) = @_;
797 ...
798 },
799 );
800
801Example, attach to the jeweler skill:
802
803 cf::object->attach (
804 type => cf::SKILL,
805 subtype => cf::SK_JEWELER,
806 on_use_skill => sub {
807 my ($sk, $ob, $part, $dir, $msg) = @_;
808 ...
809 },
810 );
811
812=item cf::CLASS::attachment $name, ...
813
814Register an attachment by C<$name> through which attachable objects of the
815given CLASS can refer to this attachment.
816
817Some classes such as deliantra maps and objects can specify attachments
818that are attached at load/instantiate time, thus the need for a name.
819
820These calls expect any number of the following handler/hook descriptions:

834(Only for C<< cf::object->attach >> calls), limits the attachment to the

836used to further limit to the given subtype).
