GUI scaling

Is it possible to actually scale a GUI control to always have a certain size on the players screen no matter his/her resolution? If not, why not Stefan? :\

Last time I tried it, it turned out looking extremely ugly. Pretty sad if that's the only way, because it ends up looking like ****.

Yeah. The only other way to do it factor screenwidth and screenheight into all your calculations and just make everything a percentage.

I suppose it would be possible to make a function that generates the proper width and height (from say widthp and heightp) when you pass a GUI object, and also sets handlers for when the screenheight/screenwidth is changed.

Don't think it'd work well with Graal, due to basically all screen resolutions being possible.

Well, actually scaling the graphics, for say different DPI, would be a different problem, because that would require scalable vector graphics (which would be a whole other path to travel down); but, resizing the controls for different screen sizes would not be difficult and potentially useful.

You can do that in pretty much all games that includes GUI scaling as well, you know, as long as they have a "Windowed Mode" option.

I rarely encounter games that support this behavior. And the game content will scale/stretch according to the resolution, while in Graal, it doesn't do that.

Problem with GUIstretch is that it uses bilinear scaling, which generally looks pretty damn bad with transparency. It would be nice if it was nearest-neighbor instead.

WoW, for one, supports it. Could name a few others on the top of my head, but it doesn't matter since there are *A LOT* of games that supports it.

Which is the whole point of this thread, we need support for that.

You are only talking about scaling the interface elements, no?

Yes, according to a predefined size on the interface.

Something like this would be cool:

PHP Code:


		
			
new GuiControl(TestControl)
{
  scale = true; // something like this, to show it should be proportional to the screen size
  x = .4; // equivalent to screenwidth*.4
  y = .5; // equivalent to screenheight*.5
  width = .5; // half the width of the screen
  height = .2; // 1/4th the height of the screen
}

Edit: If it was actually proportional to the parent control, that would be best.

This would be an awesome addition, though I'd rather seeing it work something like

PHP Code:


		
			
new GuiControl(TestControl)
{
  x = 40[percent]; // equivalent to screenwidth*.4
  y = 50[percent]; // equivalent to screenheight*.5
  width = 50[percent]; // half the width of the screen
  height = 25[percent]; // 1/4th the height of the screen
}

This forum percent sign crap really needs to be fixed z.z

Isn't that exactly what GuiStretchCtrl is doing, though? It scales all children controls with it, as well.

What's the problem with doing this?

PHP Code:


		
			
new GuiControl(TestControl)

{

  x = screenwidth*.4;

  y = screenheight/2;

  width = screenwidth/2;

  height = screenheight/4;

}

Seems like you're simply providing a different syntax for something that's already possible and not at all hard to do. Am I not understanding what's meant by 'scaling'?

The idea is that it's based on the parent control. Sure, it's possible right now, but it requires a lot more work than it should.

I guess "a lot" is subjective. Then again, I always use these 'scaling' techniques, so typing an object name is normal for me. I mean, it's just the difference between amount of characters typed.

The major difference would be that defining the dimensions using screenheight/screenwidth would result in them being set statically, once.

If they were set as percents, then they would dynamically change as the screen dimensions change.

The only way to do this currently would be hooks and something to manage all your GUI controls (which I suggested in the 4th post of this thread).
