I thought about moving the world instead of the camera, the only problem is collisions won't work since they are all sphere to something
Then this is what you do...create a pivot for the player (a child of the game world...everything except the camera is a child of the game world)...when the player moves...move the pivot and check for and process collisions (updateworld)...then move the world so that the player pivot and camera are at the same location...render world and flip...
