Question Overlaying/obscuring sprites with rectangular tilemaps basing on a "height"

Hello,

they say that picture says more than a thousand words so, below here is what I want to achieve:


I am using rectangular tilemap so the setup looks like this:


I am wondering is there something in-build into Unity tilemaps to achieve something like that?

I assume that this most probably can be done with some colliders as triggers switching sorting layers or order of a player character but it requires some logic scripting and first I would like to check if there are other options.

I also found something like "z-position" of a tile in default Grid Brush:


To be honest this last one is kind of enigmatic to me, not much in the docs (or I just can't find proper one). All I see is that I can somehow overlay tiles on the same tilemap in the same tile "slot":

5 and 10 are "z position"s of each tile.

Can it be leveraged to achieve what I want? Is there a way to set player character z position which will be interpreted in the same manner as z position of a tiles, hence influencing the rendering below/above tilemap "level"?

 

set transparency sorting axis to order by z

then set tilemap renderer mode from chunk to individual

the lower z should render above the higher z

also you can switch scene view to 3d mode so you can accurately see how the tiles are being placed

PS: that ramp is going to give you nightmares
