[Map] Player walking under a tile

[scarlet starlet]

Hi, I'm making my first steps into rom hacking (in my case, FireRed), but I've already encountered lots of problems. For example, I'm trying to revamp Route 20 using the tileset from Icefall Cave, however I noticed that the player "walks under" these two tiles:

tile 1

tile 2 (yeah it's basically the same tile, but the opposite one)

Why do these two tiles cover the player sprite? How can I make the player walk over (not under) these tiles?

Thanks in advance for your responses.

so um
this is going to be a really basic explanation ehehe

what's happening here is this, from an npc point of view it looks nicer in a code tag ok

upper tile layer
character
lower tile layer

so, there are a few things you can do
best method: set background behavior byte of the block to 20 or 22, whichever one is labelled in advancemap. this makes the specific block display differently

character
upper tile layer
lower tile layer

second method: change movement permissions and add height to the specific tiles. this might cut off surf, though, so it actually is bad
third method: add a new tile to combine the upper and lower layers. takes up possibly necessary space, so it's bad.

I usually set the background byte to "block is covered by hero" in the block editor.
