RE: [GD-General] GUI Design

[Jones, C. <CJ...@bl...>]

You could just choose a fixed resolution for layout, and scale to the
resolution you are running in.  This is what I did and it worked out fine.
It is similar to what you are suggesting, just looking at it from a
different angle.  All layout for our GUI is done as if the game runs at a
fixed 800x600 resolution.  Any time the resolution changes during game play
(including at startup), the GUI is told to adjust it's x/y scaling factors
accordingly.

Subject: [GD-General] GUI Design

I've been building a GUI for my game but from day 1 have had a design issue
I've been ignoring. From the beginning I've coded the coordinate system to
OpenGL's bottom left origin. This is a minor pain as I'm the only one who
needs to worry about the coordinates in the menu xml files (for now).

The problem however is when I resize the screen everything remains squished
in the bottom left corner of the screen. The only ay I can think of solving
the problem so it looks 'normal' is to provide some kind of virtual scaling
system that the menu is designed against that is then translated in to
screen coordinates. For example I could use something simple like 100%
equalling the width of the screen, so a box might be 20% wide 15% high at
position 5%,5%.

How have you guys solved this problem? My solution presented seems like
it'll add a whole lot more math to the GUI to do all the translations for
the virtual screen space.

Thoughts?
