Super Mario 64 Slide

Do you know how to set up a blueprint that makes your character slide in a certain directioon? You can only slide in one direction, like in this video:

What do you mean by “only slide in one direction”? Mario changes directions in the video.

I guess if you set the Walkable Floor Angle to a low value like 10, and Air Control to 1 or more, you can get basic controlled sliding.

I meant that Mario is sliding downwards. You can’t go up.
