Previously functioning camera follow script stutters in new project

Questions & Answers

Hello! I copied some scripts from an old project to a new one but for reasons I can’t figure out the camera follow script doesn’t work properly. Specifically, it stutters badly as the character moves around.

The script is the camera follow script from Sebastian Lague’s 2D Platformer tutorial (source) and it still functions as it should in my old project. The settings are all identical, the scripts are identical and the player movement script is also identical so I can’t figure out why one is stuttering and the other isn’t.

I even tried using an older (matching) version of Unity but it still stutters in the new project and not in the old project. I simply cannot figure out what’s causing this. Any ideas?

Okay after much digging through every possible project setting I finally figured this one out, although I still don’t know why it works like this:

In Edit->Project Settings-Physics2D there’s an option called ‘Auto Sync Transforms’. In my old project this was checked and in my new project this was unchecked. Checking it in my new project makes everything work like it did in the old project.
Why this makes everything work is beyond me, as I’m not using Physics2D beyond doing custom raycasts, but at least I figured out why the two projects were behaving differently.
