Attach a pre-registered attachment to an object. |

Attach handlers for global events. |

This and all following C<attach_*>-functions expect any number of the |
| 125 |
following handler/hook descriptions: |

| 127 |
=over 4 |
| 128 |
|
| 129 |
=item prio => $number |
| 130 |
|
| 131 |
Set the priority for all following handlers/hooks (unless overwritten |
| 132 |
by another C<prio> setting). Lower priority handlers get executed |
| 133 |
earlier. The default priority is C<0>, and many built-in handlers are |
| 134 |
registered at priority C<-1000>, so lower priorities should not be used |
| 135 |
unless you know what you are doing. |
| 136 |
|
| 137 |
=item on_I<event> => \&cb |
| 138 |
|
| 139 |
Call the given code reference whenever the named event happens (event is |
| 140 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
| 141 |
handlers are recognised generally depends on the type of object these |
| 142 |
handlers attach to). |
| 143 |
|

See F<include/eventinc.h> for the full list of events supported, and their |
| 145 |
class. |
| 146 |
|
| 147 |
=item package => package:: |
| 148 |
|
| 149 |
Look for sub functions of the name C<< on_I<event> >> in the given |
| 150 |
package and register them. Only handlers for eevents supported by the |
| 151 |
object/class are recognised. |

Attach handlers to all objects. Do not use this except for debugging or |

| 163 |
the game. |
