102 141
103=item cf::attach_to_type ... 142Attach handlers for global events.
143
144This and all following C<attach_*>-functions expect any number of the
145following handler/hook descriptions:
146
147=over 4
148
149=item prio => $number
150
151Set the priority for all following handlers/hooks (unless overwritten
152by another C<prio> setting). Lower priority handlers get executed
153earlier. The default priority is C<0>, and many built-in handlers are
154registered at priority C<-1000>, so lower priorities should not be used
155unless you know what you are doing.
156
157=item on_I<event> => \&cb
158
159Call the given code reference whenever the named event happens (event is
160something like C<instantiate>, C<apply>, C<use_skill> and so on, and which
161handlers are recognised generally depends on the type of object these
162handlers attach to).
163
164See F<include/eventinc.h> for the full list of events supported, and their
165class.
166
167=item package => package::
168
169Look for sub functions of the name C<< on_I<event> >> in the given
170package and register them. Only handlers for eevents supported by the
171object/class are recognised.
172
173=back
174
175=item cf::attach_to_type $object_type, $subtype, ...
176
177Attach handlers for a specific object type (e.g. TRANSPORT) and
178subtype. If C<$subtype> is zero or undef, matches all objects of the given
179type.
104 180
105=item cf::attach_to_objects ... 181=item cf::attach_to_objects ...
106 182
183Attach handlers to all objects. Do not use this except for debugging or
184very rare events, as handlers are (obviously) called for I<all> objects in
185the game.
186
107=item cf::attach_to_players ... 187=item cf::attach_to_players ...
108 188
189Attach handlers to all players.
190
109=item cf::attach_to_maps ... 191=item cf::attach_to_maps ...
110 192
111 prio => $number, # lower is earlier 193Attach handlers to all maps.
112 on_xxx => \&cb, 194
113 package => package::, 195=item cf:register_attachment $name, ...
196
197Register an attachment by name through which objects can refer to this
198attachment.
199
200=item cf:register_player_attachment $name, ...
201
202Register an attachment by name through which players can refer to this
203attachment.

414This API is preliminary (most likely, the EVENT_KLASS_xxx prefix will be
415removed in future versions), and there is no public API to access override
416results (if you must, access C<@cf::invoke_results> directly).

430Just because you have a perl object does not mean that the corresponding
431C-level object still exists. If you try to access an object that has no
432valid C counterpart anymore you get an exception at runtime. This method
433can be used to test for existence of the C object part without causing an
434exception.
