...yeah.

How might I go about this? I want it so when the hero (who has pixel based movement) walks on an npc the npc triggers.

I had something like this (for every time the npc moved)

Code:
if (key is pressed(key:UP)) then
   (
   put hero (me,heropixelX(me),heropixelY(me)--2) #PUTS HERO UP 2 PIXELS


   #The following loop determines if you are in pixel range of an item npc. If you are, the npc will activate, and you can
   #use the item or whatever.
   
   #The item npcs are 5-15 (making 10 total)   
   for (n, 0, 10) do
   (
   
if ((heropixelx(me) -- npcpixelx(npcnumber) <= 20), and, (heropixelx(me) -- npcpixelx(npcnumber) >= 0)) then
      (
   if ((heropixely(me) -- npcpixely(npcnumber) <= 20), and, (heropixely(me) -- npcpixely(npcnumber) >= 0)) then
      (
      use npc(npcnumber)
      )
      )
   
   #Move to the next npc
   npcnumber := npcnumber + 1   
   )
   
   )


But I just get script errors. Where am I going wrong? It seems so simple...Crying

From the SG3 code:

Code:
  npc:=(npcatspot((heropixelx+2)/20,heropixely/20)) #check for NPC collision
  if (getnpcid(npc)==0) then
  (
   npc:=(npcatspot((heropixelx+2)/20,heropixely/20+1))
   if (getnpcid(npc)==0) then
   (
    npc:=(npcatspot((heropixelx+18)/20,heropixely/20+1))
    if (getnpcid(npc)==0) then
    (
     npc:=(npcatspot((heropixelx+18)/20,heropixely/20))
    )
   )
  )


This could be a little more precise, but it works.

(Edit) At the end of this script, the variable "npc" will be the NPC reference of an NPC at the hero's location. You can "usenpc" on it.

(Edit) If there is no NPC, npc will be 0.

Note that it's best to use a bit of code to make up for this, Shadow.

Code:
if (npc <> 0)
then (usenpc (npc))


Yeah, very, very simple, but I just wsaid it to make sure (and for people that are reading for the sake of learning how to do the same thing and might not quite think of it).

I take it this is for collision (that is, you run into the npc. I'm horrid at reading other people's code, so thats what I figured).

I need it to activate when you step on the npc, which means when the hero is standing on the general vacinity of the npc. Would this script do this?

(sorry if I'm stupid...I just got back from six full-length courses. 18 credits of classes in one day := ugh)

Edit again: If it helps (for reference), this is basically for a point and click style aspect of the game.

Egads, I need to explain myself more in my posts.

If the hero is partially or wholly on top of the NPC, it will return that NPC's reference, which can be activated with Unc's little code snippet. If you want to make the hero have to stand more squarely on the NPC, that's not hard, but does require a little modification.
