How to force my character to unground?

I did find a way to sort-of fix this, using AddImpulse. I’m not sure if it’s the best solution, since it make the movement kinda jittery, but it seems to work for now. Will reply if I find a better solution

		AChronoCharacter *Character = Cast<AChronoCharacter>(player_ptr);
		Cast<UCharacterMovementComponent>(Character->GetMovementComponent())->AddImpulse(delta_move * 10, true);
