61=head2 OBJECT EVENTS
62
63Object events always relate to a specific object, which is always the
64first argument. Not all events get generated for every object, some are
65specific to an object type.
66
67=head3 add_bonus (item creator difficulty max_magic flags)
68
69A basic item has been created (e.g. for shops, monsters drops etc.)
70that needs bonus values applied. The B<creator> object is a template
71object that can be used to inherit stuff (and can be NULL). Flags is a
72combination of GT_ENVIRONMENT (???) or GT_STARTEQUIP (set FLAG_STARTEQUIP
73on item or set its value to 0) or GT_MINIMAL (???)
74
75When overriden, built-in bonus generation is skipped, otherwise
76treasure generation continues as it would without this hook.
77
78In general, if flags != 0 or creator != 0 you should just return and leave
79item generation to the standard code.
80

282
283Invoked when the map object gets destroyed, and only when the map object
284has a handler for this event. This event can occur many times, as its

309 331
310Invoked whenever a player leaves the B<map>. This event is likely unreliable. 332Invoked whenever a player tries to leave the B<map>. Overriding means the

339
340
341=head2 CLIENT EVENTS
342
343These events are very similar to player events, but they are might be
344handled asynchronously as soon as the command reaches the server, even when
345the player hasn't logged in yet (meaning there is no player yet).
346
347=head3 connect (client -- )
348
349Called as soon as a new connection to the server is established. Should
350not be overriden.
351
352=head3 addme (client -- )

358
359Called when the client submits a reply in the ST_CUSTOM state. Usually
360handled internally by language plugins.
361
362=head3 exticmd (client string -- )
