Looking forward to when Unity will migrate to CoreCLR. Soon! https://www.youtube.com/watch?v=_t6xVfrmEWU

That soon is like a decade in the making.

And with many folks going into alternatives like Godot, it means C# ends up losing the mindshare it got.

Yes, you can use C# with Godot, but most folks end up with GDScript, or GDextension.

> The Unity engine has evolved a lot in modern days, but I noticed a trend where Unity developers are still using "outdated" techniques when writing their C# code. Some years ago I tried to get into C# + Mono. Eventually I opted for Java instead, for many reasons; I'll skip that here. C# is very strange to me.

C# has had the reputation of not being viable for Linux for a long time. Therefore, the people already on Linux didn't have a reason to use it or even try it. If you're already doing stuff in other languages it's hardly worth it to switch to C#.

I personally use it quite a lot - but I came as a windows user writing all my utilities in C#. Also, afaik C# is mostly used in corporate environments that don't open-source their projects. You're unlikely to hear from it unless you're working on it for this very reason.

I'm a very experienced Unity C# programmer, and I certainly don't equate "good" with using all the new fancy features of a language. Fancy features are less maintainable imo. Less programmers will know about them and they're less likely to have equivalents in other languages. Making something more exotic / confusing / hard to parse is defo not worth saving a few lines of code.. I'd much rather see a longer function u…

Languages that seem to indefinitely grow more features over time (like c++, c#, rust, etc) evitably become bucketed by epochs unless the consuming application code also operate across the same time scales. Feature deprecations tend to go hand in hand with newer features, leaving you with basically "multiple sublanguages" in a supposed single language, exacerbating fragmentation of the community. I don't want to have the mental load of contextually understanding "which" sublanguages I need to care about depending on the year a consuming application was written. This is why I tend not to reach for new fangled features and stay with the core runtime stuff in evergreen langs.

A lot of game devs are terrible programmers. A friend of mine 10 years ago asked me for help with his Unity project. He is not a tech savvy person but we both took programming in high school, enough for him to make small games with a lot of tutorials and stack overflow. His codebase was horrible, a lot of logic that I would have already though of abstracting away. For example saving dialogs on json files and the cond…

This goes for devs in all industries, it's not a problem unique to games. If anything, the most competent developers in terms of getting the most performance out of hardware are game developers.

I think as a solo developer there's actually a good argument for increasing code density and coupling (things which in large multi developer projects are seen as spaghetti), as it can help you keep a lot of that code in mental and visual context at one time. It loses flexibility and readability for others, but you don't usually have enough time to concern yourself with such flexibility if you're working on a project…

This is pretty anti-thetical to most good practices but the older and more experienced I get the more(13 years as a C# dev) I think copy & pasting sections of code is wayyyyyy more appropriate than extracting into a method/class/library or other forms of abstraction.

Everything starts out with good intentions when someone comes along and says “hey you could make that an abstraction” and I just clench my jaw because I’ve seen that happen so much and then that simple clean abstraction eventually ends up being a horrible 1000 line monster that barely anyone understands and no one wants to change.

What C# version does Unity currently support? 2024 I chose Godot over Unity due to its better C# support and I can’t say that I came to regret my decision.

Iirc the lineage of their c# came from Mono, then diverged a bit over time. Hopefully they can leave that baggage behind and just use the newer .net core, if they're not already that is... Disclaimer: I haven't looked in half a decade

If you’re a solo developer, if it works. I’ve seen worse in enterprise shops and then I’ve gotten into nasty arguments with people who don’t care about programming. They can’t be wrong. C# is a high level language that can handle a degree of sloppy programming. I was working on a small tool yesterday. It was easier to vibe code it from scratch in C# than to modify an existing Rust project. The only weird part is VS C…

I would say that C# is "less colored" than Rust. Handling a moved argument, a borrowed argument, a copied argument is different in Rust, you have to think upfront about memory lifetimes. If you are wrong the first time, changing the ownership is not a simple localized refactoring.

Mono was in a usable state on Linux for literal decades before becoming official and integrated into what is core today, that is unless you needed windows forms, which much like MSFT UI frameworks today had multiple failed attempts spanning those same decades...

The other day a professional gamedev was arguing with me that's Transform.GetChild to get a reference to a component was not a bad practice. His argument is that it's what every other firms in his area is also doing. I do hope that was not the truth and he was just trying to win the argument.

For solo hobby dev it is a lot more acceptable. After all they're also terrible 3d modeler, concept artist, musician, writer, marketeer, community manager,...
