Sounds like "Migrating away from Bevy towards Unity"; the Rust to C# transition is mostly a technical consequence. Bevy: unstable, constantly regressing, with weird APIs here and there, in flux, so LLMs can't handle it well. Unity: rock-solid, stable, well-known, featureful, LLMs know it well. You ought to choose it if you want to build the game, not hack on the engine, be its internal language C#, Haskell, or PHP. T…
I love Rust, but this lines up with my experience roughly. Especially the rapid iteration. Tried things out with Bevy, but I went back to Godot. There are so many QoL things which would make Rust better for gamedev without revamping the language. Just a mode to automatically coerce between numeric types would make Rust so much more ergonomic for gamedev. But that's a really hard sell (and might be harder to implement…
What numeric types typically need conversions?
I'm usually working with positive values, and almost always with values within the range of integers f32 can safely represent (+- 16777216.0).
I want to be able to write `draw(x, y)` instead of `draw(x as u32, y as u32)`. I want to write "3" instead of "3.0". I want to stop writing "as".
It sounds silly, but it's enough to kill that gamedev flow loop. I'd love if the Rust compiler could (optionally) do that work for me.
Another failed game project in Rust. This is sad. I've been writing a metaverse client in Rust for almost five years now, which is too long.[1] Someone else set out to do something similar in C#/Unity and had something going in less than two years. This is discouraging. Ecosystem problems: The Rust 3D game dev user base is tiny. Nobody ever wrote an AAA title in Rust. Nobody has really pushed the performance issues.…
This is clearly false. The Bevy performance improvements that I and the rest of the team landed in 0.16 speak for themselves [1]: 3x faster rendering on our test scenes and excellent performance compared to other popular engines. It may be true that little work is being done on rend3, but please don't claim that there isn't work being done in other parts of the ecosystem.
Love to have this comparison analysis. Huge LOC difference between Rust and C# (64k -> 17k!!!) though I am sure that is mostly access to additional external libraries that did things they wrote by hand in Rust.
> I am sure that is mostly access to additional external libraries that did things they wrote by hand in Rust This is the biggest reason I push for C#/.NET in "serious business" where concerns like auditing and compliance are non-negotiable aspects of the software engineering process. Virtually all of the batteries are included already. For example, which 3rd party vendors we use to build products is something that c…

C# is stricter about float vs. double for literals than Rust is, and the default in C# (double) is the opposite of the one you want for gamedev. That hasn't stopped Unity from gaining enormous market share. I don't think this is remotely near the top issue.

And yet, if making your own game engine makes it intellectually stimulating enough to actually make and ship a game, usually for near free, going 10x slower is still better than going at a speed of zero.
If anything, making your own game engine makes process more frustrating, time consuming and leads to burnout quicker than ever, especially when your initial goal was just to make a game but instead you stuck figuring out your own render pipeline or inventing some other wheel. I have a headache just from thinking that at some point in engine development person would have to spend literal weeks figuring out export to A…
But part of the thing that attracted me to the game I'm making is that it would be hard to make in a standard cookie-cutter way. The novelty of the systems involved is part of the appeal, both to me and (ideally) to my customers. If/when I get some of those (:

I wish more languages would lean into having a really permissive compiler that emits a lot of warnings. I have CI so I'm never going to actually merge anything that makes warnings. But when testing, just let me do whatever I want! GHC has an -fdefer-type-errors option that lets you compile and run this code: a :: Int a = 'a' main = print "b" Which obviously doesn't typecheck since 'a' is not an Int, but will run just…
Yeah this is my absolute dream language. Something that lets you prototype as easily as Python but then compile as efficiently and safely as Rust. I thought Rust might actually fit the bill here and it is quite good but it's still far from easy to prototype in - lots of sharp edges with say modifying arrays while iterating, complex types, concurrency. Maybe Rust can be something like this with enough unsafe but I hav…

...although the fact that a 3x speed improvement was available kind of proves their point, even if it may be slightly out of date.
I really like Rust as a replacement for C++, especially given that C++ seems to become crazier every year. When reasonable, nowadays I always use Rust instead of C++. But for the vast majority of projects, I believe that C++ is not the right language, meaning that Rust isn't, either. I feel like many people choose Rust because is sounds like it's more efficient, a bit as if people went for C++ instead of a JVM langua…
Rust is very easy when you want to do easy things. You can actually just completely avoid the borrow-checker altogether if you want to. Just .clone(), or Arc/Mutex. It's what all the other languages (like Go or Java) are doing anyway. But if you want to do a difficult and complicated thing, then Rust is going to raise the guard rails. Your program won't even compile if it's unsafe. It won't let you make a buggy app.…
This just isn’t a problem in other languages I’ve used, which granted aren’t as safe.
I love Rust. But saying it’s only hard if you are doing hard things is an oversimplification.
