Hello everyone after a while browsing this forum and finding any help that I needed I'm now facing something that I would like to requires your knowledge to figure out:

Here is the thing, I've been trying parallax mapping and now i'm abble to apprehend the essential of it and make it function. Using Yanfly's region restriction my caracther can now wander but but i have like a problem.

My map look like this :

With region restriction it is set this way :

I have set the wall as an overlay as i want my character to hide under it before he gets tp into the room to make it more aestetic. The problem is that this way he can just get from the stairs to the tile that tp him.

So i've tought of something and i would like to know if something like this is doable with currents pluggins

Possible to walk : 1 ; 2 ; 3 OK
Going from 1 to 2 : OK
Going from 1 to 3 : OK
Going from 2 to 3 : NO

I know this problem on this very specific case can be solved in a very simplier way like just accept that my character is tped when he walk on the stone tile and block movements on the wall. But i can sens that this will tend to be a problem in the future. Especially with a map set up like this
If i were to build my map with the layer system then it would be no problem thanks to the database that allow exactly this function with this.
But can we have that on parallax mapping?

So in other word is it possible to have borders beetween tiles other than a full tile while using parallax mapping.

And if it is possible will it be complicated, extremely complicated, very extremely complicated.

Thanks to whomever can help me or those that took time to read me but can't help tho!
