I am fairly new to unreal engine and I would like to know how to set custom gravity in a specific point or area instead of down. For example I do not want the gravity pull to be down but more to the center of my level (center plane not center point) and that gravity to only affect specific actors. Other actors will be affected by normal gravity or affected by no gravity at all.
How can I do this? (blueprints or c++)
I know they're planning to un-hardcode Gravity [Source: I'm a moderator on the official Unreal Engine forums, I know things ;)] but the best way is to either add force in the direction you want or set the player to "Flying" mode and push him about with Launch character / Add force.
This is the only way without altering source code (Until they un-hard code gravity).
Tl;Dr - Fake it for now, A fix will come eventually!
You can not change the direction of the built-in gravity, it always points to the negative z-axis. You can also not change the gravity for single actors, only globally. But why do you need that, you can always just increase the mass of your actor.
You can easily turn off gravity completely for any actor, just look for "gravity" in the blueprint options of that actor.
I've been drifting through forums looking for what others have done for gravity solution as I'm working on centrifugal gravity in my work.
The first to counter global Z gravity to have the effect of a null gravity environment is simply add the game's gravity * delta time to Z movement while inside the zone. Then apply your own acceleration for the gravity you want.
In your situation you want to apply acceleration in the direction of your centre point.
At the moment I'm still trying to figure out how apply of Coriolis effect.
This is basic theory but it is all maths.
Hope it helps.
This topic is old but I think this video may help future visitors. What you are trying to do is possible: it's called dynamic gravity. Check this video https://www.youtube.com/watch?v=kkq5En9sG8Y
