How I make a player climb by the corners

Hello I'm trying to make an ability for my game using platform behaviour where the player can climb by the walls like wubba Mario from Super Mario Bros Wonder but I'm wanting to make him also be able to climb by corners as well

I don't know the specifics of your game, but you could try adding an invisible sprite to whichever corners you want to be climbable.

When the character is colliding with the sprite, it can trigger your climbing animation (or whatever you need).
