GUI scaling on mobile
Hello. I'm using a standard Unity GUI. I am trying to scale it to make my game playable on devices with different resolution. The problem is I can not figure out how to scale GUI properly according to the DPI of device's screen.
I tried this method https://gist.github.com/darktable/2018687 but for some reason it doesn't work for me on my mobile phone but on PC it does work (but if I change the resolution at runtime it stops working).
I am attaching two screenshots. The first one is from my mobile phone and the second is from my PC!
What I've always done is to use relative sizes in my GUI. Instead of saying this box is 50px wide, I say this box is 1.2% of Screen.Width or something similar. That way, when the screen size changes, the box changes too. Although, this is quite a painful way to do things..I usually start with my GUI laid out exactly the way I want it, absolutely, then go through and convert it to relative (by dividing the absolute numbers by the current Screen.Width)
Perhaps you could use Screen.dpi to get a better result though.
Thank you for your reply. However, if I use this method, I will have to scale the GUI's fontSize. Is it possible at runtime?
I think you have to change the font size for each element, ie GUI.skin.label.fontSize = 18 , GUI.skin.box.fontSize = 10` etc.
If I remember correctly, the trick with scaling font size is that you have to use $$anonymous$$athf.RoundToInt to round any floating point numbers to an integer, since fontSize takes an integer.
A better approach would be to create a second GUI Skin for mobile, and then switch out the whole skin when you're on a mobile device (with all your new font sizes written in the GUISkin)
I kinda hoped someone would post a better answer because relative size GUI's are nasty.
You know,
Another option is to use GUILayout ins$$anonymous$$d of GUI. Then you don't have to worry about fixed sizes, but you would still need a different font size for mobile
Could you please provide a little example of how to use the GUILayout correctly to solve my problem with scaling?
