|
|
792 | |
|
|
793 | Many objects in deliantra are so-called attachable objects. That means you can |
|
|
794 | attach callbacks/event handlers (a collection of which is called an "attachment") |
|
|
795 | to it. All such attachable objects support the following methods. |
|
|
796 | |
|
|
797 | In the following description, CLASS can be any of C<global>, C<object> |
|
|
798 | C<player>, C<client> or C<map> (i.e. the attachable objects in |
|
|
799 | Deliantra). |

|
|
808 | the specified key/value pairs as arguments. |
156 | |
809 | |
157 | =item $bool = $object->attached ($name) |
810 | Example, attach a minesweeper attachment to the given object, making it a |
|
|
811 | 10x10 minesweeper game: |
158 | |
812 | |
159 | =item $bool = $player->attached ($name) |
813 | $obj->attach (minesweeper => width => 10, height => 10); |

170 | following handler/hook descriptions: |
824 | CLASS. See the next function for an explanation of its arguments. |
|
|
825 | |
|
|
826 | You can attach to global events by using the C<cf::global> class. |
|
|
827 | |
|
|
828 | Example, log all player logins: |
|
|
829 | |
|
|
830 | cf::player->attach ( |
|
|
831 | on_login => sub { |
|
|
832 | my ($pl) = @_; |
|
|
833 | ... |
|
|
834 | }, |
|
|
835 | ); |
|
|
836 | |
|
|
837 | Example, attach to the jeweler skill: |
|
|
838 | |
|
|
839 | cf::object->attach ( |
|
|
840 | type => cf::SKILL, |
|
|
841 | subtype => cf::SK_JEWELER, |
|
|
842 | on_use_skill => sub { |

|
|
849 | |
|
|
850 | Register an attachment by C<$name> through which attachable objects of the |
|
|
851 | given CLASS can refer to this attachment. |
|
|
852 | |

853 | Some classes such as deliantra maps and objects can specify attachments |

2601 | Freezes the player and moves him/her to a special map (C<{link}>). |
|
|
2602 | |
|
|
2603 | The player should be reasonably safe there for short amounts of time (e.g. |
|
|
2604 | for loading a map). You I<MUST> call C<leave_link> as soon as possible, |
|
|
2605 | though, as the player cannot control the character while it is on the link |
|
|
2606 | map. |
|
|
2607 | |
|
|
2608 | Will never block. |

|
|
2613 | map. If the map is not valid (or omitted), the player will be moved back |
|

2614 | to the location he/she was before the call to C<enter_link>, or, if that |
|
|
2615 | fails, to the emergency map position. |
