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

244 |

root |
1.239 |
These are functions that inhibit the current coroutine one tick. cf::wait_for_tick_begin only |
258 |
root |
1.546 |
returns directly I<after> the tick processing (and consequently, can only wake one thread |
259 |
root |
1.239 |
per tick), while cf::wait_for_tick wakes up all waiters after tick processing. |
260 |
root |
1.155 |
|
261 |
root |
1.571 |
Note that cf::Wait_for_tick will immediately return when the server is not |
262 |
|
|
ticking, making it suitable for small pauses in threads that need to run |
263 |
|
|
when the server is paused. If that is not applicable (i.e. you I<really> |
264 |
|
|
want to wait, use C<$cf::WAIT_FOR_TICK>). |

=item $cf::WAIT_FOR_TICK |

Note that C<cf::wait_for_tick> is probably the correct thing to use. This |
269 |
|
|
variable contains a L<Coro::Signal> that is broadcats after every server |
270 |
|
|
tick. Calling C<< ->wait >> on it will suspend the caller until after the |
271 |

next server tick. |

Currently the same as Coro::async_pool, meaning you cannot use |
644 |
|
|
C<on_destroy>, C<join> or other gimmicks on these coroutines. The only |
645 |
|
|
thing you are allowed to do is call C<prio> on it. |

The design of Deliantra requires that the main coroutine ($Coro::main) |
654 |
|
|
is always able to handle events or runnable, as Deliantra is only |
655 |
root |
1.281 |
partly reentrant. Thus "blocking" it by e.g. waiting for I/O is not |
656 |
|
|
acceptable. |
657 |
root |
1.106 |
|
658 |
|
|
If it must be done, put the blocking parts into C<sync_job>. This will run |
659 |
|
|
the given BLOCK in another coroutine while waiting for the result. The |
660 |
|
|
server will be frozen during this time, so the block should either finish |
661 |
|
|
fast or be very important. |

940 |

941 |
root |
1.447 |
Many objects in deliantra are so-called attachable objects. That means you can |
942 |
root |
1.94 |
attach callbacks/event handlers (a collection of which is called an "attachment") |
943 |
|
|
to it. All such attachable objects support the following methods. |
944 |
|
|
|
945 |
|
|
In the following description, CLASS can be any of C<global>, C<object> |
946 |
|
|
C<player>, C<client> or C<map> (i.e. the attachable objects in |
947 |
root |
1.394 |
Deliantra). |

|
|

|
|
=item $attachable->detach ($attachment) |
954 |
|
|
|
955 |
|
|
Attach/detach a pre-registered attachment to a specific object and give it |
956 |
|
|
the specified key/value pairs as arguments. |
957 |
|
|
|
958 |

Example, attach a minesweeper attachment to the given object, making it a |

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

Example, log all player logins: |
977 |
|
|
|
978 |
|
|
cf::player->attach ( |
979 |
|
|
on_login => sub { |
980 |
|
|
my ($pl) = @_; |
981 |

... |
982 |
|
|
}, |
983 |
|
|
); |
984 |

Example, attach to the jeweler skill: |
986 |
|
|
|
987 |
|
|
cf::object->attach ( |
988 |
|
|
type => cf::SKILL, |
989 |
|
|
subtype => cf::SK_JEWELER, |
990 |
|
|
on_use_skill => sub { |
991 |
|
|
my ($sk, $ob, $part, $dir, $msg) = @_; |
992 |
|
|
... |
993 |
|
|
}, |
994 |
|
|
); |

|
|
|
996 |
|
|
=item cf::CLASS::attachment $name, ... |
997 |
|
|
|
998 |
|
|
Register an attachment by C<$name> through which attachable objects of the |
999 |
|
|
given CLASS can refer to this attachment. |

Some classes such as deliantra maps and objects can specify attachments |
1002 |
root |
1.94 |
that are attached at load/instantiate time, thus the need for a name. |
1003 |
|
|
|
1004 |
|
|
These calls expect any number of the following handler/hook descriptions: |
1005 |

|
|
|
1008 |
|
|
=item prio => $number |
1009 |
|
|
|
1010 |
|
|
Set the priority for all following handlers/hooks (unless overwritten |
1011 |
|
|
by another C<prio> setting). Lower priority handlers get executed |
1012 |
|
|
earlier. The default priority is C<0>, and many built-in handlers are |
1013 |
|
|
registered at priority C<-1000>, so lower priorities should not be used |
1014 |
|
|
unless you know what you are doing. |

root |
1.93 |
=item type => $type |
1017 |
|
|
|
1018 |
|
|
(Only for C<< cf::object->attach >> calls), limits the attachment to the |
1019 |
|
|
given type of objects only (the additional parameter C<subtype> can be |
1020 |
|
|
used to further limit to the given subtype). |

1022 |
root |
1.46 |
=item on_I<event> => \&cb |
1023 |
|
|
|
1024 |
|
|
Call the given code reference whenever the named event happens (event is |
1025 |
|
|
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
1026 |
|
|
handlers are recognised generally depends on the type of object these |
1027 |
|
|
handlers attach to). |

See F<include/eventinc.h> for the full list of events supported, and their |

Look for sub functions of the name C<< on_I<event> >> in the given |
1035 |
|
|
package and register them. Only handlers for eevents supported by the |
1036 |

Example, define an attachment called "sockpuppet" that calls the given |

event handler when a monster attacks: |
1042 |

1043 |
|
|
cf::object::attachment sockpuppet => |

on_skill_attack => sub { |

Just because you have a perl object does not mean that the corresponding |
1053 |
|
|
C-level object still exists. If you try to access an object that has no |
1054 |
|
|
valid C counterpart anymore you get an exception at runtime. This method |
1055 |
|
|
can be used to test for existence of the C object part without causing an |
1056 |
|
|
exception. |

Register a function that can be called from within map/npc scripts. The |
3498 |
|
|
function should be reasonably secure and should be put into a package name |
3499 |
|
|
like the extension. |
3500 |

3501 |
|
|
Example: register a function that gets called whenever a map script calls |
3502 |
|

C<rent::overview>, as used by the C<rent> extension. |
