=item $object->attach ($attachment, key => $value...) |

Attach a pre-registered attachment to an object. |
113 |
|
114 |
=item $player->attach ($attachment, key => $value...) |
115 |

Attach a pre-registered attachment to a map. |

122 |
=item cf::attach_global ... |
123 |
|
124 |
Attach handlers for global events. |
125 |
|
126 |
This and all following C<attach_*>-functions expect any number of the |
127 |
following handler/hook descriptions: |
128 |
|
129 |
=over 4 |
130 |
|
131 |
=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. |
148 |
|
149 |
=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. |
154 |

=back |
156 |
|
157 |
=item cf::attach_to_type $object_type, $subtype, ... |
158 |

159 |
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. |
168 |

Attach handlers to all players. |

Attach handlers to all maps. |

Register an attachment by name through which objects can refer to this |
180 |
attachment. |
