This and all following C<attach_*>-functions expect any number of the |

|
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. |

|
|
137 |
|
|
=item on_I<event> => \&cb |
138 |

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). |

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. |
