Its not working. Subspaces only seem to work to tell the NPC to use the nearest door that leads out of the current exterior cell. Ladders that are linked directly together in the same cell dont work, npc's use the ladder, disappear then reappear at the same point then use the ladder again over and over. It works fine on the balcony of a house, the npc uses the door to go thru the house to get to the player on the ground. Tho now that i think of it they dont always come out of the house, they just wait inside the front door. The tutorial doesnt go into much detail, its somewhat vague. What I'm trying to do may be outside of what the game was developed to do, there arent any ladders that lead to higher ground in the same cell. At least not that I can remember. Does anyone have any idea how to make this work because i really like the idea and its fun but when the npc's cant figure it out it breaks the experience. I may just abandon this and remove the four extra ladders Ive added to minimize then chase the player will see the enemies acting stupid "hey a ladder! how does it work? hmm to complicated for me." lol Its one of the things the vanilla game is sorely missing: cant climb a ladder to get on the castle walls... really? Im ranting now lol I just really want to make this work and i cant figure it out!! edit- This is weird but for some reason the ladder works in interior cells.
