How do I set a tile based on another tile?

Hi. I'm making a procedural dungeon game and I have tiles for every part of the wall.

Problem is, it looks like this:

I've tried something like (excuse pseudocode)

For Each Tile > Check Tile X+1 > If that is not same as X, check tile Y+1 > if Y+1 is not a tile, do not change anything (this is so it won't change horizontal walls) > If Y+1 is a tile, set tile XY to Z.

Help appreciated! Thanks.

Try this.

I'm trying to put that into my program, but nothing changes. What am I doing wrong? I initiate the bitwise method on runtime but it just stays at the default tile. (0)

Are you using the tilemap method described in the tutorial, and not the tutorial itself which uses sprites and was made before tilemap support?

Check following topic to make sprite/tile aware their neighbor/surrounding.

I have NO idea how to make this work, can someone show me how to implement it with this .capx here?

Bumping, would love some help.

Make work around tileset for the wall to match the bitwise order and end up with sprite solution. Take longer time when initiate but it works.

This is perfect. Thank you so much.

How would I set the center sprites to be black?

Like this:

Ah I was set the tile based on previous tilemap texture. Just change frame 15 from "concrete_wall" with full black square and other frames (frame 3, 6, 7, 9, 11, 12, 13, 14) with partial black.

Bumping.
