How would you go around recreating Nullscape's new movement system?

I've recently found myself coming back to scripting after not for a while but I seem to be pretty rusty. I never really grasped metatables and OOP tho so this is kinda new to me.

Currently im trying to make a custom character for the player and enemies as humanoids go against everything momentum and are just a hassle to work with/around.

good reference of what im trying to make

(picture added for a basic concept on what I thought would work)

(sorry if this is worded really bad its just really hard to word what im trying to say and also im tired, pls tell me if you dont get what im saying)

Not necessarily looking for the exact way but rather the structure of a module to make it work is what I'm not getting through my thick skull
