Make Impassable Tile Passable

[Cricketfoot]

I'm looking to make a single roof tile passable. I'd like the player to go behind a building to find a secret entrance to a building and have one tile of the roof be passable and transfer the player. Any idea how to do that?

I know I can make a special tile on a new sprite set and use that as an event, but I'd like to not have to do that for every unique tile when I decide to put in a secret passage.

Thanks for the help!

Open image edit software.

Put the roof tile in tile B and put it down in the editor like normal tiles. Then mark the passability star.

3 Other options.

The one above this.

There is a plugin that does this..Region Restrictions 

Or Make the square an event,  Above Character.

I ended up setting the Outside_A3 tileset as the D tileset which let me use that as the event graphic. This works a little funny with the autotiles since the roof tiles have a sort of left/right tile and a center tile, but for the tileset you can only choose left or right.

Thanks for the replies!
