[Other Question] Surfing player going over foreground

[hugi76]

Hello, I'm new here, here is my question, while I'm surfing, the sprite of the player is going over some foregrounds and it's not very beautiful.
It was doing doing the same with the top of the trees and houses, so I increased the prioroty of these tiles, but I can't use this strategy for these specific foregrounds I've got trouble with cause the player have to be able to walk on it. Do you know how could I make the surfing player going behind these foregrounds ?
Thank you ! (Hope my english was clear)
Kind regards
