Tried it all, the problem is that the monster won't see the onwall stuff online, i tried onwall2 but im not sure exactly how to use it...

onwall2(x,y,width,height)
if I'm not mistaken.

i know the command, but i mean what r the width and height? in tiles or screenwidth/height? also it means the area is blocked not just part of it?

Tiles I believe.
So (if im right)
onwall2(30,30,2,2)
should check if the area between (30,30) and (32,32) is on a wall.

I think thats how you use it. I don't really use onwall2 though.

is it any or all of the area?

you could try it?
it's any btw

Yeah i geuss i will onc ei fix up a few bugs in other more urgent npcs
