! plphtoo.h: the Photopia-based menu conversation object-oriented library
!
! based on phototalk.inf by Adam Cadre, the Photopia dialogue source
! object-oriented and somewhat changed into phtalkoo.h by David
! Glasser 21-Jul-1999. Adapted for Platypus by Alexandre Muņiz in 2001.

! This file is a library based on the Photopia menu conversation
! system.  Its principles differ little from Adam's binary-flag module, flags.h.
!
! Each NPC needs to inherit from the Character class.  They must each
! provide the member functions SayQ(x) and Respond(x), which print
! the xth quip's 'title' and response; Respond often does stuff in
! addition to printing the response.
!
! Each NPC should also provide an InitQuips() member function, which
! should turn on (see below) the quips that should default to being
! on. If you override the Startup() function for an NPC, be sure to call
! self.Character::Startup() in its Startup().
!
! NPC.SetQuip(42, 1) turns the NPC's quip #42 on; NPC.SetQuip(42, 0)
! turns it off.  NPC.QuipOn(42) and NPC.QuipOff(42) are shortcuts for
! the above.  NPC.QuipsOff(N, a, b, ...) turns off N quips, which are the
! rest of the arguments; N must be less than 7, as Inform only accepts 7
! arguments per function.  There is also NPC.QuipsOn, which does what you'd
! expect.  Finally, NPC.TestQuip(42) returns 1 if quip 42 is on or 0 if not.
!
! Quips are 0-based; by default, you can use fifty-six quips, from 0
! to 55.
!
! NOTE TO PHOTOTALK.INF USERS: In Adam's file, QuipOn was the tester
! and there was no shortcut for setting.  Here, TestQuip tests and
! QuipOn sets.
!
! You may wish to add life and/or orders routines to the Character
! class, and/or modify the various messages below.
!
! If any given character needs more than 56 quips, you can change
! (either in the class below or by overloading on the specific character)
! the qflag declaration to have N/8 zeros, and MAXQUIP to be N-1, where
! N is the amount of quips you want for the character, and is a multiple of
! 8.
!
! You may want to Replace some or all of AskSub, AskForSub, TellSub,
! GiveSub, ShowSub, and AnswerSub with:
!      [ FooSub; "Please use >TALK TO PLAYER to interact in this game."; ];
! and put the following into the Character class:
!      orders [; "Please use >TALK TO PLAYER to interact in this game."; ]
!
! An example can be found, commented out, at the end of this file.
