+1. People think these trigger_cvarset maps are buggy. I'm scared to copy-paste this into my engine. Also, why is 'fog' is a command and 'r_skyfog' a cvar? 

My title was one char too long. Anyway, skyfog could be an arg tacked on to the 'fog' command. 

fog has 5 values then. 

Yes. That would be more consistent with expected behaviour and compatible with engines that don't support it. The 5th value would be ignored without crashing in that case. There could still be an r_skybox cvar for players to tweak. 

one issue with that is that DarkPlaces already uses the 5th value for fog alpha, which is different than r_skyfog. Not sure if any other engines already use it for something too.

I still think skyfog as a separate worldspawn key is the way to go. 

That would be even more compatible. Again it does not preclude r_skyfog. Also I should have said 'fog DENSITY r g b'... density is more accurate 

But you probably haven't noticed that, because you're a complete cunt.

Maybe I am, but this kind of thing seems well-worth discussing even if so. Would you not think that nailing down some predictable and consistent standard behaviour in a case where a grey area remains owing to sloppy and/or weak initial standardisation is worthwhile? Is that something that could be of benefit to the entire community? 

Do whatever Preach says. :) Thanks! 

A number of old releases were made for GLQuake and never tested in WinQuake or an engine that supports fullbrights. And as a result, you have fullbright patches in the map textures.

It is possible that in the future, some sort of informational only external .ent file could tell the engine not to use fullbrights on the map textures supplied in the .bsp.

Similar to the idea of producing external .ent files signaling the author's intended r_wateralpha value for the level.

I'm just filing this thought here. 

I have problems with these on practical grounds.

A .lit file can be associated with the source .bsp by comparing the size of it with the size of the original lighting lump.

A .vis file can be associated with the source .bsp by comparing the number of leafs in it with the number of leafs in the original leafs lump.

There's no such comparison available for .ent files.

Sure, you can do string comparisons of certain fields in the worldspawn entity but it just doesn't seem as robust.

I'm aware that Quakespasm has it's own way of checking these, by means of only loading them from the same gamedir, but I can see a case where someone might want to keep these modifications in a second gamedir so they have the option of playing with either the original content or modified content.

I personally have the extended Dismal Oubliette (among other things) in a pak2.pak in ID1 so how can I be sure that a hypothetical .ent file for it - even if loaded from ID1 - refers to the original version or the extended version?

I don't pretend to have an answer to this, just highlighting potential issues as they occur to me so that we don't end up with another half-baked standard that isn't as robust as possible from the outset. 

How can you determine if an external .ent file is for the right .bsp?

Right now, you can't.

But I guess a .ent file could have some information about the expected .ent size or count it should be replacing, perhaps in the worldspawn section or some such thing. 

what about an md5 hash of the bsp file? 

how about... don't use the .ent file if it's lower on the search paths than the .bsp file of the same name?

i.e. id1/maps/e1m1.ent won't override mymod/maps/e1m1.bsp

likewise, a .ent in a pak file won't override a loose bsp in the same game dir. 

how about... don't use the .ent file if it's lower on the search paths than the .bsp file of the same name?

I'm not saying this is something that does happen, but I'd prefer a solution that can handle a case where somebody manages to get e.g a hipnotic start.ent into their ID1 directory.

This is mostly coming from reading various QuakeOne threads and observing the difficulties that people have with even getting the most basic stuff set up right. 

i think my suggestion would handle that by rejecting the start.ent (start.bsp would be later in the search path in that case.)

Hmm...

Actually a pretty good check would be to compare number of submodels in the bsp... since they are referenced in the .ent file right?

That would only fail if the .ent file doesn't use the highest-numbered submodel, which is still a point of failure i suppose. 

@metslime ... I don't think it does even now with Quakespasm's ingenious content protection scheme. 

I think QS already does what metl suggested; here's a comment from gl_model.c:

// use ent file only from the same gamedir as the map
// itself or from a searchpath with higher priority. 

yay, problem solved. 

QS seems to run significantly slower after I die and reload the map. How come? 

Shouldn't happen, I'd like to be able to reproduce that. Can you give me a scenario where it happens, like any command-line flags (heapsize), mod/map. Assuming the win32 0.90 exe? You're just pressing space to restart when dead, not loading a save? Can you see an increase in the frame times reported by r_speeds? 

what console command disables the screenflashes when grabbing powerups? 

gl_polyblend 0 

the powerup flash is built in and can't be disabled.

although, amusingly, if you type 'bf' into the console, it will play it. 

i forgot, but it's not actually 'built in', but is part of the progs.dat.
The code actually sends a 'bf' console command when you pick up items. In theory, you could make a mod to disable it. 

You could also create a modified engine that makes "bf" a command that does nothing - or have a cvar that introduces that change. I read ranger's post as looking for such a cvar, dunno if it's an existing feature in quakespasm or elsewhere...
