=item cf::attach_global ... |
| 123 |
|
| 124 |
Attach handlers for global events. |
| 125 |

This and all following C<attach_*>-functions expect any number of the |
| 127 |
following handler/hook descriptions: |

| 129 |
=over 4 |
| 130 |

=item prio => $number |
| 132 |
|
| 133 |
Set the priority for all following handlers/hooks (unless overwritten |
| 134 |
by another C<prio> setting). Lower priority handlers get executed |
| 135 |
earlier. The default priority is C<0>, and many built-in handlers are |
| 136 |
registered at priority C<-1000>, so lower priorities should not be used |
| 137 |
unless you know what you are doing. |
| 138 |
|
| 139 |
=item on_I<event> => \&cb |
| 140 |
|
| 141 |
Call the given code reference whenever the named event happens (event is |
| 142 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
| 143 |
handlers are recognised generally depends on the type of object these |
| 144 |
handlers attach to). |
| 145 |
|

See F<include/eventinc.h> for the full list of events supported, and their |
| 147 |
class. |

=item package => package:: |
| 150 |
|
| 151 |
Look for sub functions of the name C<< on_I<event> >> in the given |
| 152 |
package and register them. Only handlers for eevents supported by the |
| 153 |
object/class are recognised. |

=back |

Attach handlers for a specific object type (e.g. TRANSPORT) and |
| 160 |
subtype. If C<$subtype> is zero or undef, matches all objects of the given |
| 161 |
type. |
| 162 |
|
| 163 |
=item cf::attach_to_objects ... |
| 164 |
|
| 165 |
Attach handlers to all objects. Do not use this except for debugging or |
| 166 |
very rare events, as handlers are (obviously) called for I<all> objects in |
| 167 |
the game. |
