GoldSRC + Godot = ??? (continued)

2 years ago, I proposed this silly little idea. TL;DR imagine if you could have a GoldSRC-like workflow but in a modern engine. After all, wouldn't it be a dream for some, to be able to make full-on games in a modern engine, without any of GoldSRC's limitations?

Note: This is aimed at gamedevs who 1) want to make games the way they make HL mods 2) want their games to be moddable out of the box

So, about 2 and a half years later, here I am, coming back to this idea.
I've sailed the seven seas, climbed all hills and mountains, grown, learned, made friends, contacts, partners, all kinds of things in the meantime. I've worked with various idTech engines and their respected forks, Unigine, CryEngine, Unreal Engine, Unity (almost got a job in this, well, almost), NeoAxis, Flax Engine, Source 2 even... none of it was really a good fit for my idea.

Unigine came the closest, honestly. Nonetheless, I, one day, decided to start writing an engine from scratch. Virtual filesystem, input system, windowing, console system with CVars and commands, plugin system, all kinds of systems. Worked on it for 13 months, and it got somewhere for sure.

But then, something odd happened.

History repeats itself

Godot 4 alpha something came out with the claim that they merged .NET 6 to replace Mono. I like .NET more than Mono (it's what they use for C# scripting). I just had to check it out. After a couple nights recompiling stuff and messing with NuGet packages, I was able to get a working build with all tools. And it was LOVELY. I compiled it to try out modern C#, stayed for the UI system and all the flashy new toys they added, and most of all: volumetric fog.

I got absolutely mesmerised by it. I love fog. I love smoke. I love volumetrics in games. I fell in love with the thing. That + a few other things motivated me to consider rebuilding my engine on top of Godot, if that makes any sense. I then remembered the article I wrote over 2 years ago, and it is true what they say - history repeats itself.

And you know what? This time I actually have the skill, time and patience to actually do it! But FIRST, I needed to make sure it can actually even work.

Payback time

Do you know what's the purpose of a proof of concept?

The PoC, internally 'BodotPoc'The PoC, internally 'BodotPoc'
It proves a concept. It proves that the core idea can certainly work, and is worth prototyping. And that's exactly what you're looking at. This was a pile of code in a single Godot project, that could read Valve220 .map files, and let you move around. In the 2 weeks I programmed this thing, I learned a lot more about Godot than I did in the last 2 years.

After that, it was time to start working on the real thing.

This diagram here below, this architecture, is what gives me a great deal of convenience. I can work on the launcher, engine and games/plugins separately, without the need to re-export a Godot project if I just want to modify the "engine".

Plugin architecture overviewPlugin architecture overview
Now, before someone says "Ayo, what the HELL are you doing?", let me tell you this first: Godot is not just a game engine. It's a game engine, engine. Alright?

An engine engine. With Godot, you build your own workflow, you combine some things that you like and you use that unique combination of those things to make your game. My case is just a very special one.

In fact, here's a quote from one of their recent articles:
Godot, at its core, is and will always be (by design) a very general purpose game engine. This mean that the tools provided, while certainly capable, are still game neutral. The goal for Godot is to provide a great set of building blocks that can be used and combined to create more specialized game functions and tools.
(taken from Godot for AA/AAA game development - What's missing?)

I don't know about you, but I definitely see Godot this way. Maybe I'm more radical about it. Either way, I cannot think about making games, until I have a workflow that I truly love and am comfortable with. Godot gives me a foundation for that.

The dream

In the end, I just hope to have my dream come true: making games the way I make Half-Life mods.
And by that, I mean: making commercial games with modern technology, the way I make Half-Life mods, with modern tools and mostly without any of the bad parts of the workflow that make it incongruous.
  • I don't like the SMD+QC workflow, I just want to import a GLTF and be done with it. It is a reality we can have in HL modding even, and I'd like to write such a tool one day. It'd help beginners tremendously, I am certain in that.
  • I love the mapping workflow, but I'm not a fan of the BSP limitations. We're all very ambitious, and limitation breeds creativity... but not when that limitation is a few centimetres above your head. Can't even jump, let alone fly. Just look at AllocBlock or clipnodes. You don't want that in a modern engine, do you? An octree-based solution - as opposed to BSP - would fit this engine of mine, and even play with Godot 4's occlusion culling system pretty well.
There's several other things I could talk about, but these are the main two. Every modern engine I've worked with (except Source 2) basically had those 2 arguments up there flipped. The modelling workflow was great, mapping was not. Can I have the best of both worlds? Somehow, I convinced myself I indeed can.

At the moment

So, right now, we have:
  • a plugin system
  • a virtual filesystem with Source-style game mounting and folder structure
  • a console system
  • a placeholder game template that loads TB maps
Where we're at nowWhere we're at now

Folder structureFolder structure
What's missing is frankly a lot of stuff. Animated models, audio, networking, a main menu system, AI, mostly the need to build a proper game SDK, and flesh out parts of the engine. I have lots of ideas I want to experiment with, including entity components.

Here's a monthly breakdown:
  • map compiler
  • interactive console from BTX
  • asset loading
  • networking
  • more accurate Half-Life-style player movement
  • standard map entities
  • material system
  • basic main menu
  • a bit of documentation
  • the first developer preview
And yeah, my engine project now has a name: Elegy.

Either way, I hope to get a little game demo out by June or July. I'll be reimagining my very first game project, so that will be fun.

Right now I gotta test Elegy on Linux, deal with college and all that other stuff. See ya until then. I may eventually create a website for this project so I don't have to post about it here all the time, though it is kinda nice.

Elegy sounds like exactly the thing to get me to try Godot. This is a super ambitious project but I know from your previous stuff and watching your tutorials that you're capable of doing it!

Thank you!!!
I feel like the past 2 years (turning idTech 3 into GoldSRC, enhancing idTech 4, writing an engine from scratch) were more or less a preparation for this thing. Designing systems, understanding how my motivation works, keeping track of things via Trello and getting them done etc.

Also I forgot to mention this in the journal, but once summer's here, I will likely be looking for volunteers, mainly mappers and programmers. We'll have to see though! From experience I know stuff gets delayed, so that might as well be in autumn.

Update: we on Linux now

It manages to run on my 2012 Fujitsu S792 (Intel HD Graphics 4000 + mobile Intel Core i5 + 4 GB RAM) at about 15fps, which isn't too far off from what I expected, though NGL I kinda was hoping for 30fps... oh well, that's what I get for using Vulkan on hardware older than the API itself.

Now, I'm most likely not touching this thing until March, because February will be full of exams.

I think we might be in the presence of a modern day John Carmack here. This sounds like incredible progress man, and certainly something I'm going to be keeping an eye on. I've been fortunate enough to work within the indie games industry for the last couple of years, but to be able to make something of my own from the ground up is enticing to say the least. Just need to get my neurodivergent brain in line so that I can actually knuckle down and put the work in.

Aw thanks, but I wouldn't compare myself to Carmack in the slightest, though I will admit I draw heavy inspiration from some of his philosophy. I see him as a tinkerer who prefers practical & simplistic solutions, at least did back in the 90s, dunno how he is nowadays. And I happen to share that preference.

Anyway oof, I appear to have a nasty cold right now.

In the future this might be used to port Half-Life to modern day consoles as homebrews. There is a Godot build for the Xbox Series S so it's possible.

Grate work :)

Surprisingly there has been some. I managed to fit BTX's interactive console into Elegy, hooked it all up via ENet, so it's good. I also have a map compiler now.

I happen to be making a game in Unity, which is gonna be an excellent challenge to port to Elegy after that's done. I'm expecting to do that by September.

Nicely with a touch of sandwich!

I might even ask someday how to make a sectors generator for an engine. I guess making the sides (2 vertices down and up connected to another 2 down/up vertices) and maybe the sectors (Floor and ceiling) is easier for me to work with, but not generated UVs with offset and rotation values.
