Moving players without body movers

How do I move a player without body movers seeing as they have been removed. I also need to be able to use a look vector to determine the moving direction. I have no idea where to start, I’ve figured out moving up and down but have no idea how to use look vector with these different forces/velocity things.

Do you want the player to get knocked forward or get moved in a constant direction?

I played around with some of the new things and kind of worked it out. Sorry for being so late.
