How can I make this code work if 2 NPCs occupy same space?

[sheamkennedy]

Code: Select all

if(get NPC ID(NPC at spot(x tile, y tile)) == 1) then(
   write zone (22, x tile, y tile) 
)

Right now I have a loop that places zone #22 wherever NPC ID #1 is and if NPC #1 is not there then it erases the zone. The only problem is I have some non-obstruct NPCs that wander the map and anytime they occupy the same space as NPC #1 it causes zone #22 not to be written to NPC #1. Is there a way I can account for this? Keeping in mind there could be scenarios where up to 3 NPCs occupy the same space.

You just have to read the npc layer.
I suggest setting up a for command to run through 5 or 6 layers checking for the npc

Code: Select all

variable(spoon)
spoon:=0

 While &#40;spoon<6&#41; do,begin
    if&#40;getNPCID&#40; NPCatspot&#40;xtile,ytile,spoon&#41;  &#41;==1&#41;then&#40;
    write zone &#40;22, x tile, y tile&#41;
    &#41;
    Increment&#40;spoon&#41;
 End

The "increment(spoon)" is in the wrong place. (Edit: Spoonweaver edited and fixed his script)

Code: Select all

variable(which)
for (which, 0, NPC at spot(x tile, y tile, get count) -- 1) do (
  if (get NPC ID(NPC at spot(x tile, y tile, which)) == 1) then(
   write zone (22, x tile, y tile)
  )
)

Or you can use a while loop until "NPC at spot" returns false.

Thanks I got it figured out!
