I am just asking to see if it is possible to make a turf so when you enter it, it is non dense as well as the turf above and under it, yet you cannot walk up or down on it. A point to the right way would be nice, as well as an example if possible.

Center is the one you are on
W = turfs passable north, east, and west
M = turfs passable south, east, and west
+ = turfs passable in all directions
- = turfs passable left and right only

+W+
+-+
+M+

Also, I'm using a Rcet's Displacement Demo for my mobs multitile effect, and it seems that when I have it and my saving together at the same time and I log in the first time it works fine, for the second time, the second tile appears under my main icon instead of over, I'm looking for for help on that because I can't find a solution.

Thanks for your time... Jowy
Try something like this (warning, untested!):

mob
var
pass_n = TRUE
pass_s = TRUE
pass_w = TRUE
pass_e = TRUE

proc
clear_paths()
pass_n = TRUE
pass_s = TRUE
pass_w = TRUE
pass_e = TRUE

client
North()
return mob.pass_n
South()
return mob.pass_s
West()
return mob.pass_w
East()
return mob.pass_e

turf
var
block_n = FALSE
block_s = FALSE
block_w = FALSE
block_e = FALSE
Exited(mob/M)
mob.clear_paths()
Entered(mob/M)
M.pass_n = block_n
M.pass_s = block_s
M.pass_w = block_w
M.pass_e = block_e

That is the main setup. Now you can define your special turf like this:

turf
special
block_n = TRUE
block_s = TRUE

You can even block a single direction in the map editor by editing these values.

I hope that helps. I'm not sure why you don't want to do it with density, since it would be much easier that way. But give this a try and let me know how you fare.
Hmm...I remember doing something like this. Search for a post about me in general. Ebonshadow replied to it. Its pretty old. Good luck.
