Attach handlers for global events. |

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

|
151 |
Set the priority for all following handlers/hooks (unless overwritten |
152 |
by another C<prio> setting). Lower priority handlers get executed |
153 |
earlier. The default priority is C<0>, and many built-in handlers are |
154 |
registered at priority C<-1000>, so lower priorities should not be used |

unless you know what you are doing. |

Call the given code reference whenever the named event happens (event is |
160 |
something like C<instantiate>, C<apply>, C<use_skill> and so on, and which |
161 |
handlers are recognised generally depends on the type of object these |
162 |
handlers attach to). |

165 |
class. |

Look for sub functions of the name C<< on_I<event> >> in the given |

package and register them. Only handlers for eevents supported by the |
171 |
object/class are recognised. |

176 |

Attach handlers for a specific object type (e.g. TRANSPORT) and |
178 |
subtype. If C<$subtype> is zero or undef, matches all objects of the given |
179 |
type. |
180 |

Attach handlers to all objects. Do not use this except for debugging or |
184 |
very rare events, as handlers are (obviously) called for I<all> objects in |
185 |
the game. |

Generate a global/object/player/map-specific event with the given arguments. |

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

Just because you have a perl object does not mean that the corresponding |

C-level object still exists. If you try to access an object that has no |
432 |
valid C counterpart anymore you get an exception at runtime. This method |

can be used to test for existence of the C object part without causing an |
