Making some of the roofs passable

Hi everyone,

in my current project I run into this little issue - I want to make the player capable of walking under some of the roofs, while keeping the same autotile for passable and unpassable roofs. I'm not sure if it's even possible, but I saw someone do it with events I believe.

I know I could just copy-paste the autotile and make one of the passable, but my tilesets are full aleady so it would be nice to find a more efficient way of doing this.



Any ideas? Perhaps something to do with regions or something, I really have no clue.

Thanks!

I use Neon Blacks Terrain tags script.  It works fine for auto tiles.  

I'll have to hunt up the link.

Just for some choices :) I like this script that does it with region ids

Cool, thanks.

I'll check out the scripts and use the one that is easier to use.  ;)

Another option would be to use transparent top-layer tiles to override the autotile passability.


If you place a transparent and passable E-tile on an impassible autotile, that tile becomes passable - and because the tile itself is transparent, you can use it for any A-tile you want to be passable.


Problem with this is, you either have to remember every place where you put that invisible tile, or use a special tilesheet with markers to check where you placed it in the past. Otherwise you will always wonder where the player can go...
