What if I don't want 0,0 to be the centre?

Currently Unity2D is being a pain in the ass because for some reason I never anticipated that 0,0 would be the centre of the screen.

It’s all Unity’s fault. All of my headaches. Burn…Buurnnn! Joking!

If I moved the Camera so that 0,0 represents the top left of the screen I am then faced with misalignment when it comes to scaling or resolution changes.

I don’t really know what to post about it.

I guess I could ask if there was a way to prevent this misalignment if I had the Camera positioned where 0,0 would be the top left of the screen?

I’m too used to it like that. This 0,0 being the centre of the screen is really kicking my ass mathematics wise because of custom collision code e.g Platform Collision where physics are not involved.

What are my options?

I’m not sure, but I think it was done to make scaling simpler. Some time ago I tried to move the center to the middle of the screen (that is to move the (0, 0) point to the top-left corner), but then I rolled it back, it was more difficult to operate.
So now I use it as a center and operate with Screen.width / 2 and Screen.height / 2. Just the matter of habit.
