huddraw_virtualsize problem

**bulldozer** · January 27th, 2014, 04:38 AM

I'd like to make widescreen menus/textures for mohaa, but ran into a problem with the hud:

Code:

huddraw_virtualsize <index> <virtual> 
This let’s you set the huddraw element’s size and position according to a  virtual screen resolution of 640x480. What this means is that it lets  you treat the hud like it’s always at 640x480, and it will be properly  resized and positioned according to the actual resolution.

from Bdbodger on TMT:

virtualsize does not changes the location with different video resolution settings it is the opposite virtualsize make all displays a virtual 640x480 display so your rect coords show on all displays with different video resolution the same . The trouble with that is usually the font size gets really big and if you don't use it then the hud is in a different place with different resolution

Which file should be edited to change that 640x480 value to 1920x1080?

This is hard-coded behaviour because that is how virtualsize works. It treats each resolution as 640x480 so we can just design the HUD for such a screen.
If the actual resolution is larger, the game will auto-scale everything for us. Why 640x480? Because it is the smallest screen resolution that the game supports
and back in those days, it was still pretty common.

Changing this defeats the entire purpose of virtualsize because if you set it to 1920x1080 then you basically screwed over all the people with smaller resolutions.
Why? Because placing a backpack inside a building is easy compared to placing a building inside a backpack, metaphorically speaking. Scaling all the visual information
on a 1920x1080 screen to anything less will inevitably incur information loss.

Virtualsize actually has nothing to do with the aspect ratio. 1920x1080 has a widescreen 16:9 aspect ratio but so does 640x360. There's a 'r_customaspect' cvar which
is used along with 'r_customwidth' and 'r_customheight' if 'r_mode' is -1. Not sure how or if it works. Default it seems to be set to 1. So I'd try 2, 3 etc..

Virtualsize should be defined by a cvar then. I use 'r_customwidth 1920' and 'r_customheight 1080' with 'r_mode -1', but 'r_customaspect' does nothing.

Hm, well, it was worth a shot. But as far as I know you can't change how virtualsize works.

If you need 'widescreen' textures with huddraw, make sure the width and height of the texture has a 'widescreen' ratio.
For example, 640 / 360 equals 16 / 9.

Code:

huddraw_shader 20 "textures/black.tga" // or something
huddraw_align 20 "center" "center"
huddraw_rect 20 0 0 640 360

Virtualsize should still be able to scale it without changing the ratio.

I've been working on the widescreen version of credits.

Code:

//*** text telling the player how to skip the credits
huddraw_virtualsize 255 1
huddraw_string 255 "Press FIRE to skip the credits"
huddraw_align 255 left top
huddraw_font 255 handle-22
huddraw_color 255 1 1 1
huddraw_rect 255 205 450 0 0

If I set virtualsize to 0 the font size is ok & sharp in 1920x1080 resolution, but text position changes. If virtualsize remains 1, then this text gets bigger and blurry.

Unfortunately, that's how scaling works.

Imagine a small image 192x108 and enlarging it by factor 10 to 1920x1080. The same blurring will happen because
what was displayed as 1 pixel on the original image has to be displayed using 10 pixels on the enlarged image.

In other words, the data of the images are the same but it has to be interpolated 10 times for the enlarged image
to be displayed properly. If this didn't happen then the enlarged image would look like each pixel from the original
image is spread out surrounded by a black void (as if it were a grid with very small coloured cells and huge black borders).
