In Unity the PhysicsManager has project data. It exists across scenes but its data is unique to each project. If it make my own CustomManager, where/how to I store its data so that it's associated with the project, not a particular scene.
Most of the examples show storing data in properties in components on GameObjects but the PhysicsManager is not a component of a GameObject as far as I can tell. I want my custom manager to do whatever PhysicsManager is doing to store its data.
Any examples, pointers, links to articles?
