|
|
205 | |
|
|
206 | =item $cf::UPTIME |
|
|
207 | |
|
|
208 | The timestamp of the server start (so not actually an "uptime"). |
|
|
209 | |
|
|
210 | =item $cf::SERVER_TICK |
|
|
211 | |
|
|
212 | An unsigned integer that starts at zero when the server is started and is |
|
|
213 | incremented on every tick. |
|
|
214 | |
|
|
215 | =item $cf::NOW |
|
|
216 | |
|
|
217 | The (real) time of the last (current) server tick - updated before and |
|
|
218 | after tick processing, so this is useful only as a rough "what time is it |
|
|
219 | now" estimate. |
|
|
220 | |
|
|
221 | =item $cf::TICK |
|
|
222 | |
|
|
223 | The interval between each server tick, in seconds. |
|
|
224 | |
|
|
225 | =item $cf::RUNTIME |
|
|
226 | |
|
|
227 | The time this server has run, starts at 0 and is increased by $cf::TICK on |
|
|
228 | every server tick. |
|
|
229 | |
|
|
230 | =item $cf::CONFDIR $cf::DATADIR $cf::LIBDIR $cf::PODDIR |
|
|
231 | $cf::MAPDIR $cf::LOCALDIR $cf::TMPDIR $cf::UNIQUEDIR |
|
|
232 | $cf::PLAYERDIR $cf::RANDOMDIR $cf::BDBDIR |
|
|
233 | |
|
|
234 | Various directories - "/etc", read-only install directory, perl-library |
|
|
235 | directory, pod-directory, read-only maps directory, "/var", "/var/tmp", |
|
|
236 | unique-items directory, player file directory, random maps directory and |
|
|
237 | database environment. |
|
|
238 | |
|
|
239 | =item $cf::LOADAVG |
|
|
240 | |
|
|
241 | The current CPU load on the server (alpha-smoothed), as a value between 0 |
|
|
242 | (none) and 1 (overloaded), indicating how much time is spent on processing |
|
|
243 | objects per tick. Healthy values are < 0.5. |
|
|
244 | |
|
|
245 | =item $cf::LOAD |
|
|
246 | |
|
|
247 | The raw value load value from the last tick. |
|
|
248 | |
|
|
249 | =item %cf::CFG |
|
|
250 | |
|
|
251 | Configuration for the server, loaded from C</etc/deliantra-server/config>, or |
|
|
252 | from wherever your confdir points to. |
|
|
253 | |
|
|
254 | =item cf::wait_for_tick, cf::wait_for_tick_begin |
|
|
255 | |
|
|
256 | These are functions that inhibit the current coroutine one tick. |
|
|
257 | cf::wait_for_tick_begin only returns directly I<after> the tick |
|
|
258 | processing (and consequently, can only wake one thread per tick), while |
|
|
259 | cf::wait_for_tick wakes up all waiters after tick processing. |
|
|
260 | |
|
|
261 | Note that cf::wait_for_tick will immediately return when the server is not |
|
|
262 | ticking, making it suitable for small pauses in threads that need to run |
|
|
263 | when the server is paused. If that is not applicable (i.e. you I<really> |
|
|
264 | want to wait, use C<$cf::WAIT_FOR_TICK>). |
|
|
265 | |
|
|
266 | =item $cf::WAIT_FOR_TICK |
|
|
267 | |
|
|
268 | 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. |

278 | =item @cf::INVOKE_RESULTS |
|
|
279 | |
|
|
280 | This array contains the results of the last C<invoke ()> call. When |
|
|
281 | C<cf::override> is called C<@cf::INVOKE_RESULTS> is set to the parameters of |
|

935 | =head2 ATTACHABLE OBJECTS |
|
|
936 | |
|
|
937 | Many objects in deliantra are so-called attachable objects. That means you can |
|
|
938 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
939 | to it. All such attachable objects support the following methods. |
|
|
940 | |
|
|
941 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
942 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
943 | Deliantra). |
|
|
944 | |
|
|
945 | =over 4 |
|
|
946 | |
|
|
947 | =item $attachable->attach ($attachment, key => $value...) |
|
|
948 | |
|
|
949 | =item $attachable->detach ($attachment) |
|
|
950 | |
|
|
951 | Attach/detach a pre-registered attachment to a specific object and give it |
|
|
952 | the specified key/value pairs as arguments. |
|
|
953 | |
|
|
954 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
955 | 10x10 minesweeper game: |
|
|
956 | |
|
|
957 | $obj->attach (minesweeper => width => 10, height => 10); |
|
|
958 | |
|
|
959 | =item $bool = $attachable->attached ($name) |
|
|
960 | |
|
|
961 | Checks wether the named attachment is currently attached to the object. |
|
|
962 | |
|
|
963 | =item cf::CLASS->attach ... |
|
|
964 | |
|
|
965 | =item cf::CLASS->detach ... |
|
|
966 | |
|
|
967 | Define an anonymous attachment and attach it to all objects of the given |
|
|
968 | CLASS. See the next function for an explanation of its arguments. |
|
|
969 | |
|
|
970 | You can attach to global events by using the C<cf::global> class. |
|
|
971 | |
|
|
972 | Example, log all player logins: |
|
|
973 | |
|
|
974 | cf::player->attach ( |
|
|
975 | on_login => sub { |
|
|
976 | my ($pl) = @_; |
|
|
977 | ... |
|
|
978 | }, |
|
|
979 | ); |
|
|
980 | |
|
|
981 | Example, attach to the jeweler skill: |
|
|
982 | |
|
|
983 | cf::object->attach ( |
|
|
984 | type => cf::SKILL, |
|
|
985 | subtype => cf::SK_JEWELER, |
|
|
986 | on_use_skill => sub { |
|
|
987 | my ($sk, $ob, $part, $dir, $msg) = @_; |
|
|
988 | ... |
|
|
989 | }, |
|
|
990 | ); |
|
|
991 | |
|
|
992 | =item cf::CLASS::attachment $name, ... |
|
|
993 | |
|
|
994 | Register an attachment by C<$name> through which attachable objects of the |
|
|
995 | given CLASS can refer to this attachment. |
|
|
996 | |
|
|
997 | Some classes such as deliantra maps and objects can specify attachments |
|
|
998 | that are attached at load/instantiate time, thus the need for a name. |
|
|
999 | |
|
|
1000 | These calls expect any number of the following handler/hook descriptions: |
|
|
1001 | |
|
|
1002 | =over 4 |
|
|
1003 | |
|
|
1004 | =item prio => $number |
|
|
1005 | |
|
|
1006 | Set the priority for all following handlers/hooks (unless overwritten |
|
|
1007 | by another C<prio> setting). Lower priority handlers get executed |
|
|
1008 | earlier. The default priority is C<0>, and many built-in handlers are |
|
|
1009 | registered at priority C<-1000>, so lower priorities should not be used |
|
|
1010 | unless you know what you are doing. |
|
|
1011 | |
|
|
1012 | =item type => $type |
|
|
1013 | |
|
|
1014 | (Only for C<< cf::object->attach >> calls), limits the attachment to the |
|
|
1015 | given type of objects only (the additional parameter C<subtype> can be |
|
|
1016 | used to further limit to the given subtype). |
|
|
1017 | |
|
|
1018 | =item on_I<event> => \&cb |
|
|
1019 | |
|
|
1020 | Call the given code reference whenever the named event happens (event is |
|
|
1021 | something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
|
|
1022 | handlers are recognised generally depends on the type of object these |
|
|
1023 | handlers attach to). |
|
|
1024 | |
|
|
1025 | See F<include/eventinc.h> for the full list of events supported, and their |
|
|
1026 | class. |
|
|
1027 | |
113 | package => package::, |
1028 | =item package => package:: |
|
|
1029 | |
|
|
1030 | Look for sub functions of the name C<< on_I<event> >> in the given |
|
|
1031 | package and register them. Only handlers for eevents supported by the |
|
|
1032 | object/class are recognised. |
|
|
1033 | |
|
|
1034 | =back |
|
|
1035 | |
|
|
1036 | Example, define an attachment called "sockpuppet" that calls the given |
|
|
1037 | event handler when a monster attacks: |
|
|
1038 | |
|
|
1039 | cf::object::attachment sockpuppet => |
|
|
1040 | on_skill_attack => sub { |
|
|
1041 | my ($self, $victim) = @_; |
|
|
1042 | ... |
|
|
1043 | } |
|
|
1044 | } |
|
|
1045 | |
|
|
1046 | =item $attachable->valid |
|
|
1047 | |
|
|
1048 | Just because you have a perl object does not mean that the corresponding |
|
|
1049 | C-level object still exists. If you try to access an object that has no |
|
|
1050 | valid C counterpart anymore you get an exception at runtime. This method |
|
|
1051 | can be used to test for existence of the C object part without causing an |
|
|
1052 | exception. |
