i don't know if 5 months counts as necro but if it is leave it in peace. and delete this.
II've been drifting through forumforums looking for what otherothers have done for gravity solution a i'm workas I'm working on a centrifugal gravity in my work.
The first to counter global Z gravity of global to mayhave the effect of a null gravity environment is simply add the gamegame's gravity * delta time to Z Movementmovement while inside the zone. Then apply your own acceleration for the gravity you want.
In youyour situation you want to apply acceleration in the direction of youyour centre point.
At the moment iI'm still trying to figure out how apply of corealasCoriolis effect.
This is basebasic theory but it is all maths.
Hope it helphelps.
