Bug: No more whole numbers in 3.0.0. :S


Recommended Posts

Just updated my DR to 3.0.0, and began aligning my textures, when I noticed that it stepped from whole numbers, to very slightly off numbers, like for example:
0 - 1 - 2 - 3.0000000000000004 - 4 - 5 - 6.000000000000001 - 7.000000000000001 - 8.
These numbers are consistent when using both the horizontal and vertical shift buttons. Even when I try to manually type in "6", it adjusts it to "6.000000000000001".

I'm afraid to texture things now, because I want textures to be in whole numbers.

It's just the representation in the editor. The map file itself is identical.

2.14:

Version 2
// entity 0
{
"classname" "worldspawn"
// primitive 0
{
brushDef3
{
( 0 0 1 -64 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 1 0 -7.5 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 1 0 0 -7.5 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 0 -1 -64 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 -1 0 -8 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( -1 0 0 -7.5 ) ( ( 0.0625 0 -0.1875 ) ( 0 0.0625 0.828125 ) ) "_default" 0 0 0
}
}
}

3.0

Version 2
// entity 0
{
"classname" "worldspawn"
// primitive 0
{
brushDef3
{
( 0 0 1 -64 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 1 0 -7.5 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 1 0 0 -7.5 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 0 -1 -64 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0
( 0 -1 0 -8 ) ( ( 0.0625 0 0 ) ( 0 0.0625 0 ) ) "_default" 0 0 0

}
}
}

 

No extra 0's with a 1 on the end.

I always assumed I'd taste like boot leather.

No harmful behaviour here, it's just a formatting issue, the underlying value doesn't differ.

The difference between 2.14 and 3.0 is the fmtlib version DR is using. It appears that the fmtlib update to version 8.1.1 introduced a change in formatting behaviour when omitting the format specifier. Explicitly setting the format specifier to "g" removes the rounding of the rightmost digits:

fmt::format("{0:g}", value)

And @Nort, I'd appreciate you editing your status update to clarify the situation, to not needlessly get people scared about map corruption.

Sure. I'll do that. Just understand that I was actually pretty scared there for a moment.

Since this bug also affects the rotation step value, you actually lose the ability to enter such a value completely, and have to rely on direct input, or only rotate in 90 degrees, in order to rotate textures.

Hopefully solving this, will also solve the nasty effects I sometimes get when I use "Fit" with certain values, and the texture just becomes some kind of smear.

      Please, can we finally group the missions by year in the game menu?

      I vaguely recall someone recently complained about two-sided materials (curtains?) not getting lighting from both sides
      I just found a piece of code that's supposed to do just that
      Where was that discussed? (@nbohr1more?)

      I still play classic Doom (albeit with user-made mods and maps rather than the original campaign) on a regular basis. A game from the early 90's which has still got a healthy following in 2022. Pretty amazing.

      I'm beginning to understand why people who aren't into social clubbing "don't last long" on this project, and why it's so full of holes. When moderators are siding with bullies, by closing down threads that they derail, then I start to wonder if I should support the platform to begin with.
      I'm sure that the core development is solid, but when you're constantly tone policed and bullied, and moderators are playing into it too, then the project will just drive away talent, and replace it with socialites instead. ...and without talent, you only end up with a small skeleton crew trying to do everything themselves.
      ...so Dragofer and Airship Ballet, and all you other socialites, you win. From now on I'll just keep to myself. You'll never be able to do my work, but at least you'll be happy together, and that's what matters to you.
       
      Update
      Actually, I have to revise my statement:
      I actually messaged greebo - the top dog, I gather - about nbohr1more's outburst of insanity below, and since I haven't even heard back from him, I just have to assume that there's not a single core programmer here, who's not backing nbohr's threats. ...and that's bad.
      ...so if you're a newbie reading this, or an honest soul like ZergRush, then just slowly back out of these forums, run, and don't look back. This is nothing more than a cult posing as a game development project, using Thief and IDTech4 to sucker hopefuls in, to do work for them, while trying to cajole them into something going on behind the scenes, which apparently - according to nbohr - is something that should be hidden from the state. These people aren't programmers - they don't even understand things like how to fix the simplest bugs. All they have, is an engine, and an IP, and some sort of fascist social cult. There was some other project I saw being made in the Unreal Engine. Try joining that project. ...or start a project of your own. Anything but this asylum.
      Hopefully that was "divisive" enough for a final post, because at this point I really want people to leave this place. This project is, on a management level, just awful garbage, run by garbage people, apparently from the top down, and I'm just glad that they have a garbage place to stay, together, and hopefully forever.
