How to invert the gravity for a character?

I’m making a game where one of the features is that the character can walk either on the roof or the floor switching between both with a button press. My character for now is the one that comes by default on the Side Scroller Template and i would like to know how can i make it so that when the player presses a button or there’s some kind of event, the character will stop walking on the floor and it’ll fall upwards to the ceiling and keep walking there? something like inverting it’s gravity. My project is blueprints only so i’d like it most if the solution was blueprints only.

Multiply it with -1

(Negative One)

I thought so too, but i can’t find any way to set the gravity of a character in blueprints while the game is running

Well, had to write my own gravity to solve my problem.
