- I'm making a voxel engine with RUST! (the programming language...)
I originally was making my voxel game with Unity, but my love for the Rust programming language caused me to see if it's viable to swap over to that.
My voxel engine is now REALLY FAST! I've optimzied it over a month, and I'm going all in on Rust.

"This parser is the best one... So I'm going to write my own." - the philosophy of every project/video by Tantan in one sentence. XD
Lmao! That may be a bit more true than I like to admit :p
Making wheels is fun
You can filter the log entries with the log crate, env_logger allows the user to control this with with an environment variable.
I was trying to decide if my next project would be in Rust or C++, but after this, I will definitely do it in Rust
The language is so nice! And all the tools around it make it even better. If you start with new projects, Rust is worth taking a look at. Game dev is also coming along. Just look up "are we game yet" it is a wonderful website to see what is out there in terms of crates/libs.
because you're transgender?
I've been working on an OpenGL/Vulkan engine front-end written entirely in Java for the last 6 months. I plan on having the Engine build-process implement a previously compiled runtime binary written in C++; in which the project resources, libraries, and data/logic structures are compiled to C++ source format. Programming languages are tools limited by our own preconceptions . Attempting to implement development pipelines that differ from the current-standard can only lead to industry changing success or a minor inconvenient failure.
@Glizzster i'm surprised youtube didn't delete that comment automagically
@@loli42 I think it did, cause I can't see the comment you're referring to 😂
I might be wrong but I think you could've made a new logging level "Tantan" and log your stuff at that level, then only show "Tantan" logging level in imgui. That way you can avoid wgpu-rs 's logging.
```rust
env_logger::Builder::new().filter(Some("wgpu-rs"), log::LevelFilter::Off).init()
```
Could work too
the only reason you havent blown up on youtube is because your target audience is pretty small. As soon as Rust gains more popularity you are going to get a lot more subscribers. Keep up the amazing work!
don't jinx it
I feel like the demand vs supply of Rust videos is pretty poggers atm.
The demand might not be that huge, but the amount of people creating content like me is, well are there anyone more than me? Because I want more Rust content to watch ;)
@@Tantandev Haha totally agree with you! Hopefully I'll have my own Rust TH-cam content out there in the near future. :)
@@Tantandev There's the channel Let's Get Rusty.
I like how passionate you are with rust :D
Yeah me to haha, love the language
The `log` crate isn't really a logger itself but just a logging facade, which presents a standard interface for logging which various logging implementations can provide. Other people have mentioned `env_logger` which is one of these implementations, which lets you configure the logging through environment variables. If you want logs to go to your log console though you'll probably need to write your own implementation, but I know that `env_logger` allows filtering of logs by package so it should be possible to do similar filtering in your own implementation.
RUST > every other modern programming language
Certainly feels that way the more I learn it, so intuitive to use
Jajaja, I read the YT commentary: "I'm making a voxel engine with RUST! (the programming language...)". It is kind of sad that you have to specify, that is a programming language and not a game :D
Always that you make a new video, I want to take back Rust, but... Maybe later. I will continue with C++ :D
I just love this project and your videos about it! :D
Btw. log messages using the log crate consist of a target, a level (info, error, etc.) and a message. The target usually refers to the module that logs something. There are multiple compatible logger implementations (env_logger, simplelog, flexi_logger, etc.) and I'm sure some or even most of them support filtering by target ;-)
Oh Awesome! I didn't put that much time into the log lib, needing to rush the video out. I'm gonna revisit it, and add the filter by target method. Super cool if many other libraries had a log implementation like wgpu-rs.
Gonna be nice to be able to filter it out :)
Ahh yes, I understand exactly what you just said… good video man :)
This is so awesome! Those speed optimizations are fantastic. The async threads def seemed to be helpful!
Your videos are really well made and cool
Thanks! Motivation++;
I love your videos and you projects.
Thank you!
motivation_juice += 1
Awesome stuff! Great to see these small components being made that we usually dont pay attention to. Even without rust knowledge, I could follow through, great vid!
🎉 epic. Liking the explanations; can't wait to see how you tackle networking
Yeah networking will be super interesting!
Just getting into rust and this is really fun to watch!
Side note about macros: check out the official rustlang book. The section on macros will take you less than an hour and you’ll know how to implement macros in the way you described. They’re really simple.
Wow. This is getting really good! :D Your editing quality has skyrocketed! :D
i ❤️ Rust. its freaking awsome.!!
Then can I ask you for tips on how to learn it?
I want to learn Rust because its a language I see being used more in the future, and I do like the idea of it.
Also, who doesn't like having more tools in their tool-belts?
Programming background:
I come from C# (Unity & Modding) and C++ (OpenGL beginner).
@@Xeros08 iam still learning it. and the best way to learn rust is to create something with it.
I learned some basics of rust from TH-cam, and tried out macroquad (A game Library for rust ), and thats how I learned rust.
And now iam learning wgpu-rs, for making a 3d Game engine.
also i challenged myself to learn rust in 1 week .
And rust isn't that hard. you get used to it.
@@rootwayder77 wait... I was suppose to say that! Haha you had a very similar path to me.
The official book is super awesome, got me through the basics, then watching youtube videos on Rust.
I did a lot of short projects. Was very goal oriented because I wanted to make videos on it (got motivation and drive from that).
I made small game clones with different frameworks Macroquad, ggez, Bevy.
@@Xeros08 Starting with a small project is always good (I would not start with GPU stuff though), just some console app might be better to get started.
Good place to start is combination of: "Rust by Example" and "Rust Book" (just search for them, both free online resources) also "Are we game yet" if you want to start with GPU/game stuff.
Best to learn a bit of Rust before diving into game stuff though, don't want to figure 2 things out at once. And compiler is your friend, and Clippy too (cargo-clippy).
Im going for log4rs in my project which plays nicely with the log library. You can set levels for each module which makes slective logging a breeze
Amazing work! please continue like this!
Thanks, that's the plan!
RUST RUST RUST RUST
Rust RUsT rust RUST!
awesome work dude, keep it up!
Thanks for the motivation juice!
Ah my rust guy here! RUST RUST RUST! lmao. Why tf youtube "forgot" notifications argh.
omg yes
Yes indeed
ok now this is epic
I concur
Thanks :p
Do you know, its shorter when you call `wgpu-rs` with its full name *web gpu rs*
Even shorter with web gpu rust.
@@warkah7557 so true LOL😂
But then it just sounds like a bunch of random computer terms
@@warkah7557i i've got shorter: web graphics processing unit rust
Yes but it is kind of fun to say XD
Keep up the good work!!!
Roger that!
rust is now on my resume after watching tantan rust vids.
hashbrown vs std hashmap is strage, beacause quote "Since Rust 1.36, this is now the HashMap implementation for the Rust standard library. " So it should not show any changes
yeah I was on an older Rust version so I updated it :D
Tantan uploaded woooooo!!!!!!
Content: Tan out of Tan
aww your optimization videos inspire me to do more optimization on voxel stuff 😅😄
oh yea a new tantan video.
Yay! Thanks for the motivation juice!
@@Tantandev Thanks for all of the videos you made, every video is very fun to watch.
frick parallel iterators all my homies hate parallel iterators
great video as always my digeridoo dude. glad you're learning stuff and having fun instead of banging your head against a wall which is like 99% of my dev experiences lmao
Lmao!
There might be some wall banging from time to time, we are after all programm3R~ee I mean human
Got this in my recommendation pog
I'm not a rust dev nor interested to be rn but I have to listen that super voice :D addictive.
How are the compile times in Rust vs Unity?
Edit: Awesome progress btw!
Hm that's a good idea to try out, I'm on a little vacation at the moment, I'll try to remember checking it out when I get back
@@Tantandev I'll "await" for that info ⏳
love your style and energy KEEP IT UP!
Rasstt, rasstt, raaaassttt, rasst.
I had no doubt, it's rust, and as always, Cool!
"cri alot" :D A layk that!
Your programming skills is epic.
Can you make VR game with Rust?
It can be a challenge for you 😊
really enjoyed this video! :)
std::collections::HashMap actually uses hashbrown under the hood. So... it shouldn't be any faster. You are probably noticing a speedup because hashbrown's default Hasher is AHash, which is "not secure," hence it's not used by default in std. But all you need to do is use the ahash crate to use it with the std HashMap.
yes! I was using an older version of Rust, but after updating it std::hashmap is now using hashbrown
Might have to borrow some of the ideas here for my own project
Of course, be my guest!
For the command parsing, why not just split the line by spaces (or use a crate like shlex to split it like bash does), and then parse the arguments using a standard CLI parser, e.g clap, structopt etc? Then you can just make a struct to hold your arguments and derive a parser for it automatically. This would take literally minutes to set up and has all the features you could possibly want :)
Did you really benchmark the difference using hashbrown? Because actually since Rust 1.36 the HashMap in the standard library is hashbrown ;-)
Ooh I might be on an older Rust version, maybe time to update :)
@@Tantandev The difference is probably std using siphash 1-3 as the hashing algorithm, and hashbrown using hash, which is much faster.
about the focus thing on egui. You need a minumum version of 0.14.1 if I remeber correctly to have the lost_focus() thing to work with enter.
👋 rust, rUst, RUSt, RUST 🤚
Rust, rust, rUST RUST!
You could turn off wgpu-rs logging with log4rs crate
Ay new vid
Ay it's Nyx! :D
Have you thought of adapting the Veloren engine to an editable world game like Minecraft? It is a very smooth Rust voxel game, but you cannot build or mine freely.
nah, I think I wanna go a similar route to cube world or veloren where the game focuses more on exploration than mining and building things :)
@Taylor Worthington Note that Veloren has a build mode, through it (as well as build persistence) need to be turned on by a server admin.
Curious what your thoughts are on Amethyst. I've just started investing into and it looks really cool
I wish I could like twice
I wish I could like this comment twice
Wait... I guess I can give a heart also
Hey, love the content as always! I've been wondering but how what would you recommend to a beginner starting 3D Graphics with Rust? (what should I start with etc) I've tried to start with sothr wgpu docs but I didn't find it to be completely beginner friendly, but it was great nonetheless.
take a look to macroquad
Wgpu-rs requires a lot of what feels like boilerplate code. It's very intense at the start due to the amount of text you need to type out. (Gets good later though when you start using different features)
I would probably learn glium at the start, it's an opengl wrapper. You could then follow the popular learn open gl website(I believe it's in C++, but applicable).
Or use gliums own tutorials I believe they have.
Graphics programming took me personally a few attempts to get into(doing full tutorials multiple times).
Sleep on it, revisit it, and push through when you can.
It's a whole new world to get into :p
@@Tantandev Thanks a lot for taking the time to reply! After doing a bit more of research, I think i'm going to first start slowly by learning OpenGL, it seems there is a couple of good tutorials (in C++) then try to convert it to Rust, it may take weeks (even months?) but I feel like i'll learn a lot in both graphics development and Rust.
Next video: I made Minecraft with Rust.
Instead of using std::sync::mpsc, you should try crossbeam-channel, it has more features and better performance
Really enjoying these videos man. Great work, I'm super motivated to finally stick to learning Rust after watching these
Why don't you make a Discord server?
I'd be down for it :)
I have one!

Super cool. I've only dipped my toe in with some CLI stuff, any recommendations for where to start with GUI/CGI for rust?
My experience with GUI/CGI in Rust is very minimal, so I'm afraid I can't point you in any particular direction.
Some resources I always use are rust websites that start with "arewe(+insert_topic)yet".
You can search for "are we gui yet" and a bunch of resources related to gui will be displayed.
I also enjoy arewegamesyet.rs for rust resources related to game development
Hi
Which OS are you using Linux or Windows ?
Why you dont use C++ ?
Is Rust faster than C++ ?
Are you using OpenGL ?
What is your opinion ?
i don't see any video for the unity version!!!
heyy, what CPU is the worldgen done on? (specs)
I think he mentions it on his previous video
i need help, how did you store the data of the voxels? Did you use a lib for that or did you do with VECs
Don't know if you did it already, but for voxel meshes, you really need to implement greedy meshing.
Reduces the number of vertices needed.
If you're optimising for chunk load performance, this can (depending on a number of factors) make the problem even worse.
@@jsbarretto Yes, it can make chunks loading slower (plenty of procesing that has to be done when generating the mesh).
But if this is is a voxel engine for a game, it's an optimization worth looking into, in my opinon.
@@Xeros08 yeah, that's a method I like to try in the future!
But time to try to make a game ;)
Want a little break from optimization
@@Tantandev Understandable.
Do you think Unity could handle a full fledged game with work or is the rendering too slow?
I believe Unity would handle the rendering just fine.
I want to use Rust mainly because I enjoy writing in it more than C#
@@Tantandev I want to use C# more than C++ because of syntax and features, so I can relate. I have always wanted to learn Rust, but am more interested in making a game than an engine.
Bro, whats your colour scheme?
Well, Unity would be much faster if you'll use ECS :)
9:14 Loop through a HashMap? You are loosing the power of the fast access this way...
umm rust reminds me of Rust, can we remake it here? :p
:3
;∆
cpu cores, not gpu, eh
Rust Voxel Engine? Just call it the Rustel Engine
big fan of rust and voxels, but meshing voxels is boring :))))
you should redo your renderer at some point and raytrace voxel octrees, it could be more performant than meshing and it will allow you to do crazy good lighting effects.
just a challenge :)
Yeah I probably should some time, but I wanna make a game ;)
It probably takes a good amount of time to learn raytracing
@@Tantandev very true, my comment was more to be funny anyway, but it didnt come out very well. Love the series anyway, keep it up :)

Can someone explain a voxel for dummies? Vids on here explaining it you need to be a genius to understand. Someone really needs to make a video explaining it for a normal person to understand HINT HINT
a voxel is like a pixel but in three dimensions
Hey, men can make a game engine using java please , it would be interesting for me as a java game developer
Hey, men can learn Rust and be happy
@@rustmc yes, sure men
Rust or rust, it's family
Check out Thin Matrix here on TH-cam, he has a bunch of videos developing his own Java game engine with which he already published a game and is currently working on another
@@MindSwipe thanks men
This channel is amazing and fun!
Awesome. Wasn't sure if I should give Rust a try for once, but now I'm hyped 😅 Besides that: Awesome editing, subscribed 🤘
Hey thanks, welcome aboard! :)
next randall here. Switch from engine to just a programming language.
Let’s go tantan
Yes let's go Jamzy!
It's so satisfying seeing the improvements. Fantastic job getting improving this so much.
Can’t rendering the chunks be offloaded to the gpu?
I'm not sure what you mean, could you elaborate? The chunk data is sent to the gpu, currently there is a draw call for every single chunk though
@@Tantandev ohh, okay, Looked like you were only using cpu’s for the voxel, ty
Love your work❤️❤️
Thanks homie!
this is sooooooooooo cool!!!
