Proof of Concept for a 2d camera that loops infinitely regardless of map size and aspect ratio

Potential Improvements

Adjust for aspect ratio change mid-scene
Consolidate to one management script or a prefab
Add a swipe controlled Dolly
- Add a 'sway' factor to lag behind camera rig's momentum

Main Camera
- TrailCamera
SceneLeftRoot !!y=0!!
- Map background
- - SceneRightRoot !!y=0!!
- <All GameObjects to exist "on" the map>

Attached to the Main Camera. This script:

Identifies the map length by the distance between SceneLeftRoot and SceneRightRoot
Keeps the TrailCamera a set distance away from the primary camera
Jumps the main camera to the rightmost and leftmost boundaries when needed

Attached to the SceneLeftRoot object. This script:

OnStart() Adjusts the SceneLeftRoot position to be the starting leftmost position on Camera

Purpose: By dynamically positioning the root onStart(), we account for all aspect ratios

Attached to the Main Camera for no particular reason. Just needs access to calculate or ask for Map Length. This script:

Has a "SpinningRoot" game object that you give it
Will rotate assigned object based on current camera position:
- Starting position is 0° rotation
- Quarterway through the map is 90° rotation
- Halfway point is 180° rotation
- etc
