Proportional gui scale and position

[Melonslise]

I want my gui to maintain position and size proportional to the screen resolution and not be affected by the gui scale factor.

To keep the size I've tried many different ways like getting the gui scale factor from the settings, dividing the resolution by the texture dimensions and so on, but I haven't been successful so far.

I also don't understand how the position affects drawing a texture. I thought that positions would be relative to resolution, but I've found that setting anything more than around ~400 will cause the texture to disappear completely (considering I have a 1080p screen).

How would be harmful to accessibility and usability of the mod? The gui can't be interacted with anyway so I doubt it would be much of a problem.

 

How do I invert the glScale using the gui scaling factor? From what I've tested the factor returns strange values like 0 for auto, 1 for small, 2 for normal, etc. This isn't particularly helpful.

Well in my case I'm actually improving the readability. I need the gui stretched across almost the whole screen.

 

I've gathered as much by now. As I said, the problem lies in the values of the scale factor (at least the one I'm getting from the game settings). I wouldn't be able to to divide by 0 for instance.

Look at how the GUI scale factor is used to set the GL scale factor. There is probably a formula or conditional statement somewhere.

I did a tutorial on this some time ago and although its a bad one, you may find some ideas there on how you will do it. Mine was pretty much hard coded though

Have you tried setting xSize, ySize, guiLeft and guiTop? For example:

 

@Override
	public void initGui() {
		super.initGui();
		
		xSize=width-10;
		ySize=height-10;
		guiLeft=(width-xSize)/2;
		guiTop=(height-ySize)/2;
	}

"width" and "height" fields are the ones that scale when screen size changes.
