Perspective camera "zooms in" when increasing window height

Questions
1

Hi,

I have a basic project(in Defold 1.12.1) with a perspective camera(auto aspect ratio) that looks at a sprite. The game window resolution is 320x320.

It looks like this:

orig_res
orig_res320×349 10.9 KB

If I increase the window width, the sprite keeps it’s size:

increase_width
increase_width947×359 13.8 KB

If I increase the window height, the sprite looks bigger (doesn’t fit in the window anymore):

increase_height
increase_height330×691 20.2 KB

Is this behaviour intended? What’s the reason for it?

I find it really strange that there’s a difference between changing width and height. Also, I wasn’t expecting any kind of “zooming” without changing FOV or distance between camera and sprite.

On better thought, I guess it makes sense that the FOV of the camera is drawn over the entire window height, so whenever I change the height I get to see the camera FOV drawn on different number of pixels.

I think this question can be deleted !
