Soooo, I tried to take a look at the scripting system and I have a pretty basic question.

Is there any simple way to script an NPC in such a way that it will act if an entity appears at a position relative to that same NPC? (so, for example, if a monster moves to the tile directly south of the NPC, it stabs that monster)

I know it's possible to script a seperate gigantic script that scans every tile of the room and stores its content into a bunch of variables and use that as a reference, but that kinda beats the "simple" limit. :p

Like this:

Label loop
  Set var "_MyScriptX" = _MyX
  Set var "_MyScriptY" = _MyY + 2
  If ... 
        Wait for entity Monster 0,0,0,0
     Set var "_MyScriptX" = -9999
     Set var "_MyScriptY" = -9999
     Move 0,1,1,0
     Move 0,-1,1,0
  If End 
  Set var "_MyScriptX" = -9999
  Set var "_MyScriptY" = -9999
  Wait 0
  Go to loop

This particular script will check the tile two squares south of the character. If a monster crosses that tile, it steps south, then north. (I made it two squares to allow room for the character's sword.) To check other directions, change "MyX" to "MyX - 2" for west, "MyX + 2" for east, and change "MyY + 2" to "MyY - 2" for north. The movement commands will require a similar adjustment.

oooooooh, so does that mean that the _MyScriptX/Y variables have an effect how the script interprets coordinates?

Thanks a lot for answering this.

Yes. Also, the _MyScript W and H refer to width and height, respectively (for script commands such as Wait for Entity... that could conceivably take those arguments).

The coordinates are measured from the top left corner of the map, and increase as you move down and right.
