!
! This code allows one to simulate torches (the flaming, wooden kind).
! One can have good ones (ready to be ignited), burning ones, and
! burned-out ones.  
!
!
! Include this file sometime after VerbLib.
!
!
! Somewhere at the beginning of your code, you'll need to set the
! following constants:
!
! Constant TORCH_COUNT = 18;	! how many torches in the game
! Constant TORCH_VARIANCE = 7;	! some randomness
! Constant TORCH_LIFE = 50;	! how many moves a torch will last
! Constant TORCH_DECLINE = 5;	! torch starts sputtering
! Constant TORCH_DYING = 1;	! torch is about to go out
!
! Here is a handy way to give the player a burning torch at the
! begining of the game.  Use it in the Initialize() function.
!
!	move players_torch to player;
!	players_torch.power = TORCH_LIFE;
!	StartDaemon(players_torch);
!
! Make sure that you've actually created players_torch somewhere outside
! of the functions.  Do it like this:
!
!	BurningTorch players_torch;
!
! Now, when you want to have some torches sitting around for the player
! to pick up, do this:
!
!	UnlitTorch ->;
!
! That will create one unlit torch.  When picked up, the game will
! respond with "You pull the unlit torch off the wall".  Similarly, you
! can use "BurningTorch ->;" to have a burning torch stuck on a wall.
! The same goes for a dead torch.  Count up all the times you do this
! and put that number as TORCH_COUNT (see above).
!
! You shouldn't need to modify anything below this point.  If you do,
! please let me know why and how you modified the code.
