Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why ECS pattern is popular in Rust?
The question arises from seeing a plethora of projects using ECS: hecs , Bevy , specs, legion

Want to learn how to make games with Rust and the Bevy game engine? Now is a great time to jump in with the recently released Bevy version 0.10. I created a Bevy 0.10 beginner tutorial video series for those looking to learn and join our game dev community!
Instead, I'm using now the specs Library. It's a pure ECS library and much less powerful, without any visualization capabilities, but its works for me :)

Is implementing an ECS in rust a bad idea for a beginner project?
writing an ECS is defined a challenging project, no matter the language or if you're a beginner. although it is entirely possible to write one in Rust, check out specs and bevy_ecs for examples.

Ecs fundamentally at odds with borrow checker.

Veloren is releasing 0.13!
The official 3d rendering client uses a custom engine called Voxygen. They use Specs for logic.

How are rust devs doing?
Rust has a delightful ECS library, specs, that I absolutely love. It has safe multi-threaded execution built right in, which is fantastic for the pretty parallelizable work I was doing. Concurrency in C++ is nasty business on the best of days, and I've run into so many nasty bugs with the custom system I've had to build out to fit the web's weird threading model.

Programming a Rogue-Like with Rust
Man, this Specs [0] library is so strange to me, coming from a Unity background. Is there some sort of comparison as to why one way is better than the other?

Bellclone: a simple 2D game about jumping
Hi everyone - I just picked up one of my long-unfinished side project built with Rust and would like to show it to you here. It's a clone of the famous(?) Winterbells game. It's written entirely in Rust and uses OpenGL and an entity-component-system architecture ([the `specs` crate](https://crates.io/crates/specs)) (still learning), no game engine.
-
There are a *lot* of actor framework projects on Cargo.
Wait did the person at your company write specs or something else because they weren't pleased with it? I don't know much about amethyst and vaguely know about entity component systems but I watched a talk on someone making a game with amethyst and was pretty impressed -- it looked thoroughly approachable and I do not doubt the performance is there (since the whole reason you do ECS is performance).

Ask HN: Is Scratch a good tool for teaching coding?
I know that code.org's lessons have a "view the real code" box, helping to ease one into the "here's how to think about problems and structure, but here's the actual JavaScript that underpins it". If you haven't tried that, it may help
I also recently learned that Brilliant uses block-based lessons, too, so there's obviously some there-there
I would guess that a lot of the problem is one of actualization: how does one go from solving "someone else's problems" to one of realizing their own ideas. Based on what I've seen, I'd guess that a Minecraft mod port that maps blockly down into lua would go a long way toward "do some things that materialize change in an environment that is familiar." I haven't used Roblox, but I believe it's similar so if they have a programming language, same-same. I started to suggest using Valoren <https://gitlab.com/veloren/veloren#get-veloren> since it's actual FOSS and thus would be much, much easier to integrate into, but I haven't played it in order to know how much uncanny-valley it would have with any preexisting Minecraft experience

Veloren Future?
Firstly, it's open-source. That means that all code associated with the project is freely available (it's right here!) and you're welcome to download, modify, recompile, and make changes to it as you wish. In fact, there have already been a few forks of the project that added new items, abilities, bosses, and other such things. Veloren is also released under GPL v3, a license that pretty much ensures that the code will always be open-source, meaning that anybody can take the existing code and remix it, mod it, or otherwise build upon it.

New license for veloren assets?

Veloren won't launch on Fedora 37 with amdgpu Graphics.
sounds like a wayland issue, can you check our https://gitlab.com/veloren/veloren/-/issues list and if you dont find this error, you could help us by opening a bug and giving it a good description: Maybe there is even a workaround in our book:
- Could something like this be implemented in Veloren? I'm not a Dev but this video by LTT makes Async look promising

C Isn't a Programming Language Anymore
Trying to replace C with something like Rust, is essentially saying that we should rewrite all kernels in Rust. C is the common language because it talks to the kernel, which talks to the hardware.
Forgetting how much would need to be replaced with objectively much slower code, Rust simply cannot do some things. You cannot always make absolute guarantees about memory safety for example when it comes to low-level programming. Sometimes to be fast, you have to make assumptions and take risks.
I am currently watching the Veloron game [1] as an example of how larger Rust projects may begin to look. I see something like this [2] and it doesn't look all dissimilar from C, just with a new syntax. Has writing this game eliminated all bugs? Nope [3]. Maybe there are less segfaults and bad memory management, but this was just one class of bugs.
