! Version 2! Fixes a a bug that Imi pointed out, and stops them from trampling
!  over other NPCs and objects. They'll still walk off of the edge of a world,
! and appear on the other side, so be sure to wall them in :)
! NOTE: To use this you must put a WALKER npc type in your DCCTOKEN.DAT file!

! In my script there is animation, but I opted to leave it out of this simply
! because not everyone has drawn tiles for all NPCs. It is very easy to add if
! you want, but if you have trouble doing so, just ask me at
! abyssdragon@juno.com and I'll send you my script with instructions on how
! the blocks are arranged for it.

 if npc.class = walker then
  L1 = npc.x;
  L2 = npc.y;
  L3 = 0;
  L0 = random(4);
  if L0 = 0 then
   if world.density(L1,L2 + 1) > 0 goto END_WALKER;
   L4 = locate(npc,L1,L2 + 1);
   if L4 > -1 goto END_WALKER;
   L5 = locate(object,L1,L2 + 1);
   if L5 > -1 goto END_WALKER;
   inc(npc.y);
  elsif L0 = 1 then
   if world.density(L1,L2 - 1) > 0 goto END_WALKER;
   L4 = locate(npc,L1,L2 - 1);
   if L4 > -1 goto END_WALKER;
   L5 = locate(object,L1,L2 - 1);
   if L5 > -1 goto END_WALKER;
   dec(npc.y);
  elsif L0 = 2 then
   if world.density(L1 - 1,L2) > 0 goto END_WALKER;
   L4 = locate(npc,L1 - 1,L2);
   if L4 > -1 goto END_WALKER;
   L5 = locate(object,L1 - 1,L2);
   if L5 > -1 goto END_WALKER;
   dec(npc.x);
  elsif L0 = 3 then
   if world.density(L1 + 1,L2) > 0 goto END_WALKER;
   L4 = locate(npc,L1 + 1,L2);
   if L4 > -1 goto END_WALKER;
   L5  = locate(object,L1 + 1,L2);
   if L5 > -1 goto END_WALKER;
   inc(npc.x);
  endif;
 endif;
:END_WALKER
! THE END!
