How do I make objects ignore walls?

[Wally]

I am making a platformer game with enemies, and one of those enemies is a ghost. I want to make said ghost ignore walls while not destroying them. Is there a way to make its so the ghost ignores walls and passes through them? Thanks!

this block in the sprites category has a lot of options; you want the bottom option, “ghost through walls”
