static int attempt_hide ( object *  op, object *  skill  )

static

Someone is trying to hide. The user becomes undetectable (not just 'invisible') for a short while (success and duration dependant on player SK_level, dexterity, charisma, and map difficulty). Players have a good chance of becoming 'unhidden' if they move and like invisiblity will be come visible if they attack Implemented by b.t. (thoma.nosp@m.s@as.nosp@m.tro.p.nosp@m.su.e.nosp@m.du) July 7, 1995 - made hiding possible for monsters. -b.t.

Parameters

op	living trying to hide.
skill	hiding skill.

Return values

0	op couldn't hide.
1	op successfully hide.

static object* find_throw_ob ( object *  op, const char *  request  )

static

Find an object to throw. If we request an object, then we search for it in the inventory of the owner (you've got to be carrying something in order to throw it!). If we didnt request an object, then the top object in inventory (that is "throwable", ie no throwing your skills away!) is the object of choice. Also check to see if object is 'throwable' (ie not applied cursed obj, worn, etc).

Parameters

op	object wishing to throw.
request	requested item to throw.

Returns

throwable object, NULL if none suitable found.

int singing	(	object *	pl,

Singing skill handling. This skill allows the player to pacify nearby creatures. There are few limitations on who/what kind of non-player creatures that may be pacified. Right now, a player may pacify creatures which have Int == 0. In this routine, once successfully pacified the creature gets Int=1. Thus, a player may only pacify a creature once. BTW, I appologize for the naming of the skill, I couldnt think of anything better! -b.t.
