Entity Shenanigans

hello

i am currently working on an entity that has the ability to float, it usually walks and i intended for the floating to be a sort of fail save incase the entity cannot climb a hill/wall/obsticle. i want it to basically start floating up to the players location for example when the player is standing on a large hill without a way for the entity to climb up, i want it to start floating and hover/pathfind towards the player, would anybody we able to maybe show me a screenshot of a procedure that would make that work out? or maybe just tell me in a way that is helpful?

thanks!
