Top Down orientation (Where is positive Y?)

Hi!

I did the course on Paper2D from the learning hub (excellent course!) and I noticed for the top down example that ingame the top of the screen is negative Y and the bottom is positive Y of world space. Is this a general convention? I am very familiar with this from other 2D dev environments, but so far I assumed that Unreal used the convention that positive Y is “north” so to speak. So I would have expected that in a 2D game, the Y axis goes from bottom to top, not vice versa.

I would just like to make sure that I follow along with conventions before starting my game and having to flip everything eventually.

Thanks
