Do you know the Custom Gravity Project?

Link: Unreal Engine 4 : Custom Gravity Plugin
(This project)

I would like to use it for my project. However, I have a problem by expanding. the custom gravity project consists of Pawn class, not Character class. I need its function as Charater class.
I should use ‘character class’ + ‘movementcomponent(component)’, or I want to inherit movementcomponent to character class.
Please tell me how to do it.

ex) (using pawn class) I collide to the wall by jumpping, the character`s falling speed is slower than usual. However, when I play character class(no inherit movementcomponent), the problem disappers.
