109
110=item $object->attach ($attachment, key => $value...)
111
112Attach a pre-registered attachment to an object.
113
114=item $player->attach ($attachment, key => $value...)
115
116Attach a pre-registered attachment to a player.
117
118=item $map->attach ($attachment, key => $value...) # not yet persistent
119
120Attach a pre-registered attachment to a map.
121
122=item cf::attach_global ...
123
124Attach handlers for global events.
125
126This and all following C<attach_*>-functions expect any number of the
127following handler/hook descriptions:
128
129=over 4
130
131=item prio => $number
132
133Set the priority for all following handlers/hooks (unless overwritten
134by another C<prio> setting). Lower priority handlers get executed
135earlier. The default priority is C<0>, and many built-in handlers are
136registered at priority C<-1000>, so lower priorities should not be used
137unless you know what you are doing.
138
139=item on_I<event> => \&cb
140
141Call the given code reference whenever the named event happens (event is
142something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
143handlers are recognised generally depends on the type of object these
144handlers attach to).
145
146See F<include/eventinc.h> for the full list of events supported, and their
147class.
148
149=item package => package::
150
151Look for sub functions of the name C<< on_I<event> >> in the given
152package and register them. Only handlers for eevents supported by the
153object/class are recognised.
154
155=back
156
157=item cf::attach_to_type $object_type, $subtype, ...
158
159Attach handlers for a specific object type (e.g. TRANSPORT) and
160subtype. If C<$subtype> is zero or undef, matches all objects of the given
161type.
162
163=item cf::attach_to_objects ...
164
165Attach handlers to all objects. Do not use this except for debugging or
166very rare events, as handlers are (obviously) called for I<all> objects in
167the game.
168
169=item cf::attach_to_players ...
170
171Attach handlers to all players.
172
173=item cf::attach_to_maps ...
174
175Attach handlers to all maps.
176
177=item cf:register_attachment $name, ...
