Here's mine: earth.suncapped.com (https://github.com/Suncapped/babs)
It's been ongoing for 12 years, with several burnouts and rewrites, hah.
If you want, I would love to talk offline (email in profile) about player-freedom, MMO projects, and browser games. I feel like some of us have a shared history going back to older MMOs [0] and Flash browser games [1].
On my project, I sneaked past the hard networking problems by settling on tile-based movement. It worked for Ultima Online and I still believe in it. It scales really well. Networking zones measure 1000 x 1000, and tiles are 4 units, so X and Z can each be stored in 1 byte. This also helps with storing and transmitting tons of objects. See the page load time.
Actually, I sneaked past a lot of difficult things, which is what strikes me about your work - you solved hard stuff directly. I haven't tried to integrate skeletal animations into my Blender pipeline yet. Yikes. I barely know how to write cameras, whereas you made a cross-platform one and blogged about it.

How did this one go? I ended up literally doing a `ln` for shared frontend/backend files.

This is such an interesting aspect of web games: HTML-based UIs. I went with Svelte because I was curious about it. It is SO much easier than doing a game UI yes. But the "line" between web UI and game UI keeps being a problem. For example, when a player drags an object into a UI backpack: That object's graphic needs to change from 3D mesh -> mouse cursor -> png icon. Craziness. I might scupper the whole thing.
A bit of a ramble, but in conclusion, wow!! Thanks for sharing this.
0: UO, Lineage, you said Exteel which I'd like to learn about.
1: (First Earth had a Flash version lol. Also a Babylonjs version.)
I am neither a web dev nor (especially) game dev expert , but I recently came across this crossroads when building a small js canvas game. Should I use html elements styled with css for my game UI?
After a very short time thinking about it I decided not to implement the UI this way. It seems like a good idea because html and css are easy to use. Much easier to style a button and assign it a js function than draw buttons on the canvas and check if they’ve been clicked. But I felt like it spanned a boundary that might prove hard to reconcile in some scenarios, but that was more of an instinct than a well reasoned conclusion. I’m curious what others think about it.
My biggest surprise was, before I jumped in I figured there would probably be some existing "RPG inventory" libraries I could build from, that handled dragging icons around between icon slots etc. But I never found any game-oriented UI projects I could use, and ended up building entirely from scratch.
I host an indie gamedev coworking group in the bay area and on discord that you might find interesting. Will DM you.

Very easy with module imports. Same scene graph and entity component system shared between client and server.

> React+Redux setup was too much performance overhead for the real-time gameplay section. The state updates through the Redux action reducer pipeline, and the minimal React render updates were enough to cause noticeable hiccups in the gameplay frame rate. Performance in the browser environment is susceptible to garbage collector management. To minimize garbage collector hits, you need to use object pooling. Object pooling is a mutable state management pattern in which you pre-allocate a pool of objects. The collection of allocated objects gets mutated and reused during the program's life to minimize runtime memory allocations. This object pooling pattern conflicts with the immutable update patterns of React and Redux. Hitting these performance issues was a significant roadblock and essentially became a 'rewrite' in which I had to rewrite the game state management to be performance optimized. This rewrite was costly and took a lot of time.
This is 100% the conclusion I came to when trying to build a web-first game from a React/JS background and it's wildly reassuring to read someone else coming to similar conclusions.
If you, for example, hold your voxel level data in a big array, that means copying that data every time the level is modified.
You are more likely to a struct of arrays than an array of structs/objects as well. Very handy in C but also JS.
I suppose you can use a sliding window object (or “fly” object) that pretends to be the object when the data is really split across various arrays, just don’t actually loop over them. ;) I bet someone has done a library for something this way and used proxies.
Thank you, as someone that has struggled trying things in new spaces I'm sure I've missed out on learning from others who came before me, hit a wall, and then walked away taking their knowledge with them.
I appreciate you sharing your story and work for others.
Babylon.js, cool. How did it do with voxels, or how did you work with it? If you feel like answering. I used it previously on my project.
I have to check out all the other games on that list [0].
As for what I'd do differently - I should have ignored it. I invested a fair bit of emotional energy into trying get info, doing some work that the Babylon team asked for in hopes it would lead somewhere, etc. But nothing came of it and it was pretty depressing; I'd have been happier if I'd just tweeted once and moved on.
(I guess technically I should also have bugged Mojang to comply with the MIT license by adding my code's copyright notice, but... life is short.)
Re: Babylon.js, it doesn't have any voxel-related features, so to be honest all the babylon-specific code in my engine would probably look very similar if I'd gone with three.js. But Babylon's real killer feature is definitely its forum, which is extremely helpful and active. I'd probably never have been able to build my engine in three, just because I don't know any way of getting answers to thorny "oh you need to set mesh._dirty before calling that API" type questions for it.
Impressive dedication, congratulations!
I did something similar when I was 23. (Now two decades ago - wow...) That project wasn't a runaway success on its own, but it was a fundamental learning experience. Those years spent building a software project of my own, yet one meant for other people to use and extend, completely changed how I think about my career and life and its external dependencies.
I spent months trying to make a CS like in Three.js, then I was wondering myself if it was actually worth it
I could just have used a random game engine that can export to WebGL with wasm even if the first loading was bigger, people wouldn't even notice nowadays
WebGPU is coming out if I'm correct, I wonder how good will web games run now
Ahh I want to share my browser 3d (tiny) mmo project!
It doesn’t work on mobile:
I totally agree with the issue with browser build sizes. It is not nice with bigger engines! I was even hesitant to use React because I wanted to keep things minimal but it is too nice. Lol
I'm the author of VoxLords, one of my early Voxel engines written for the web. Super fun to see/read about other projects like this!
My last webgl voxel-engine was this one: https://github.com/Lallassu/voxelengine3 (a bit more optimized than the VoxLords one) :)
Borderline satire.
UI, simple as it seems to some and complex to others, seems to still be a problem that there is no simple solutions to, they all carry a lot of accidental complexity, web UIs or not.
By the way, I tried to use an immediate mode game UI in the past (Lua-based, SUIT), but somehow I feel more comfortable working with object-based UIs. Perhaps years of object-oriented programming has damaged my brain a bit :)
I think in the past the object-oriented was seen as a big improvement regarding GUI dev, but I guess with regards to game dev, it can be problematic wrt performance.

> I wanted to recreate a canceled MMO called Exteel in an .io style.
I think it should be “a .io style,” since the next letter pronounced is d.
On the other hand, "Microsoft .NET" includes the "dot", as well as "bought five .com domains". Yet in contrast, "bought five .edu domains" would usually be said without the dot.
Hypothesis: we don't pronounce leading dots unless for some reason they've become part of well-known "branding", like .NET or .com.
Then it's like Alice in Wonderland.
Also, I’m impressed that you can remember the obstacles you overcame several years ago. Landon entropy, m1 conversion, etc.
I host a bay area indie gamedev coworking group. The coworking group's regular recurring meetup interval kept me in a peer pressure and positive feedback loop. I also felt the need in the market had not been addressed until this new wave of engines started appearing.
> I’m impressed that you can remember the obstacles you overcame several years ago.
I kept a daily journal in org-mode and separate dev log file. Can search through this and my commit history for lots of info.
