I already learned to easily simulate 0 gravity by “add force” or impulse inside a Blue Print actor.
But I want to give an impulse to my actors, and they should stop (like if moving inside a dense liquid). You can see this behavior in this amazing game:
The physical simulation properties have a drag and roll (angular) resistance setting.
Set them both to something big, like 0.1 to slow them down significantly when moving.
This is assuming that your Pawn is using physics movement. If you’re instead using Character and CharacterMovementComponent, you will have to change the Character-specific tuning constants, because those are not the same physics.
