I worked for Kitware. All the cmake maintainers agree the Cmake syntax is terrible, especially the legacy stuff. There have been a ton of overhauls to ergonomics but the old clunky abstractions are still all over tutorials everywhere. But well-written CMake actually mostly solves the "builds on my machine!" problem. I've also seen some of the most horrific abuse of CMake you could imagine.

[@TheSulross]

There are some books on CMake but couple of the top titles I got I found are very lacking. The world still needs a best (modern) practices CMake book that covers enough real-world scenarios to be actually useful. Need a Scott Meyers kind of author for the subject of CMake. And should cover integrating git projects and C++ modules.

[@isodoubIet]

my conspiracy theory is that kitware intentionally keeps cmake terrible in order to sell the books written by their developers. Nothing else makes sense. The supposed overhauls actually make things worse, e.g. nobody with a brain in their head would've come up with generator expressions if they _actually_ were trying to improve things.

[@defeqel6537]

If you actually have ownership (edit: transfer), then *_ptr may be valid, but it's not really required very often. Littering your code with shared_ptr is a great way to make your code slow(ish). That whole vector is an architectural mistake in anything that is not a hobby project, and is a very Rusty thing to do

[@cherloire7978]

@@defeqel6537 whats the alternative?

[@Vendetta405]

Please avoid using std::vector in production code. It's likely better to use something like std::vector and handle runtime dispatch without a virtual table, possibly using enums within the data. Combining a contiguous memory container like a vector with random memory references from smart pointers negates the advantages of cache-friendly access patterns, potentially giving you the worst of both worlds. In well-structured C++ codebases, patterns like this are rarely seen.

[@DeerDesigner]

Well, it’s your lucky day because in production rust codebases such patterns are rarely seen as well! I’m commenting on the fact that in this very video and in many corners of the internet people are constantly praising using *_ptr in C++ while those same people complain about using stuff like Arc in Rust. You can’t have it both ways. Rust simply forces you to think consciously about who’s owning the data and for how long.

Can anyone explain the OOP is not for games thing? The only way OOP has ever made any sense as a useful construct to me is in gamedev analogies

[@adam7802]

[@adali228]

For larger or more complex games it generally has worse performance than something like ECS, but it's perfectly fine to use for the vast majority of non-AAA games.

[@RoyaltyInTraining.]

Having objects / structs which combine data and code is universally considered a good thing. But most people take the term "OOP" to also imply using inheritance, which often leads game developers to dead ends. Game development massively favors composition. Basically that means instead of having "Enemy", "MovingEnemy", and "ShootingMovingEnemy" classes which inherit from one another, you have one "Enemy" component, one "AIMovement" component, and one "AIShooting" component, which you can plug into the objects in your game. In case you want an example of how inheritance leads to dead ends: Imagine you want something in your game that moves and shoots, but isn't considered an enemy. Then you would have to duplicate that entire branch of inheritance when using OOP, but with composition you could just use those two components without any extra work.

[@hanifarroisimukhlis5989]

Easy answer: Lifetimes. Traditional lifetime of data is from first use until last use, but in games you need to "kill" objects without dangling reference.

[@ClimateChangeDoesntBargain]

OOP is bad for max performance, you want to do some data oriented design which benefits from less pointer hops and cache friendliness

[@Me-wi6ym]

This comment section feels like a warzone. Am I the only one who just kinda likes both languages? Neither are perfect and both can be messy, but both can make pretty cool things too if you take some time to consider the design; you know, the same as all the other languages. This shouldn't be the part people are stuck on.

[@9636dev]

I agree, when writing C++ code tends to be more verbose, but for me the development velocity is a lot faster, but I do think about security a lot less, leading to many race conditions and sometimes memory leaks

[@ITSecNEO]

No, C++ is messy by default. Every company has their own C++ subset or rules for programming and formatting. All the newer features which people often refer to in defense of C++, are not included in the subsets anyways. Just Google a bit and you will find out that the most used version in 2024 is still C++11. Just imagine what all those poor souls need to go through everyday.

Rust have more videos on KZbin than actual production code, everyone one trying to sell you Rust otherwise would be dead, and another thing really strange about rust is the brainwash on people about rewriting everything in rust, rust have it’s use cases as any other language, there is not a single language efficient and good for everything

[@ionaerofeeff]

I think it's that Rust somehow absorbs your desire to write code in it, due to how satisfying and easy it is to write and build, respectively. It has a simpler-to-understand package system than python, and great portability which is enhanced by community packages. It's fun, I guess. And at that point it can be tempting to write things in Rust for the goal of both learning Rust even better and becoming more familiar with a certain algorithm or procedure, as the whole process can be smoother-feeling than a number of other languages with generally pretty-good performance across the board. And as the video covers, it helps to eliminate a lot of footguns present in other languages by making it difficult to write some of the riskier or error-prone code, ESPECIALLY if you use an LSP. Clippy helps this yet more, as it highlights not just errors but potentially confusing or suboptimal parts of code, and (almost?) always for an understandable reason. That being said, you still get a lot of the freedom in Rust that you do in other languages. Which isn't to say that people SHOULD be doing that, just that it has a lot about it which encourages it. I do agree that people should widen their scope when looking for the right tool for the job.

@@ionaerofeeff Rust is great for systems programming which is what it was originally designed for where correctness stands above all else. It's horrible for webdev or especially gamedev where development and iteration speed are way more important than correctness. In the time a Rust backend dev spent refactoring his entire codebase to add 1 simple feature, the Typescript dev added 20 more. In the time a Rust gamedev spent refactoring his entire codebase to implement 1 idea, the C++ gamedev came up with 20 new ideas, implemented them, tested them, selected out the good ones and made the code good. Of course if you're writing an operating system where a small memory issue could cause a critical RCE vulnerability Rust is important, but in webdev and gamedev putting out trash fast and polishing it along the way is the only way to actually make progress.

When it comes to package management for build systems, I personally reckon there's a balance. To use rust as an example, I would ideally want to use crates while I'm getting things working, and then work on removing those dependencies which can be easily removed, and fixing the others to a specific version (which can be later updated as necessary), for the simple reason that all else being equal, fewer dependencies is probably better. Of course, one particularly nice thing about Cargo is that you can specify where a given dependency should be drawn from, making vendoring easier to accomplish regardless.

OOP was designed to be close to how you visualise relations in real-life. It can be very annoying but most games do represent real-life so it kinda works well. That being said, unless you're game is going to be a very realistic simulation, it's still going to have its problems. Personally, I'm huge fan of data-oriented ECS. It does have a learning curve but it's amazing. The main problem however, is trying to get the game designers (and even some of the programmers) to adjust to it. A lot of the ECS systems on my project aren't as good as we want them to be just because the design team still wants some degree of control over them while using their existing OOP workflow. However, recently, performance has been a concern so we have essentially been given the green light to prioritise it over the designers' feelings. Can't wait.

@moonasha You might be surprised. OOP is not as common in software that needs to be highly efficient or squeeze the maximum performance out, the abstractions themselves are far from zero cost, but especially the way that objects get laid out and processed in memory is particularly poor for performance. As one AAA example that I know something about, Skyrim is as far as I know written in C++ but the actual important parts of the game is implemented as a huge number of tables. There is no class for weapons with subclasses for each type, there are itemdef table entries with an integer that encodes the type of item, if it's a weapon what type of weapon it is, etc etc. The mod tools for editing any of the lower level data for the game is basically the interface for editing a 20GiB database, it's just thousands upon thousands of tables of columnar data.

Cmake is a horribly designed mess from beginning to end. They tried to improve things with "modern" cmake but the "targets and usage requirements graph" model is instantly shown to be the colander of leaky abstractions when used on a real project, and things like "generator expressions" flatly shouldn't exist.

[@wolfgangrohringer820]

@@isodoubIet On top, one usually doesn't get to choose "which" CMake to use, old-school or declarative. Depending on the libraries you want to pull in, you end up having to deal with the whole depth of it anyways.

[@isodoubIet]

@@wolfgangrohringer820 yep, and even being "modern" is no guarantee of it makign sense. One example is libtorch -- they somehow list as their "usage requirements" that you must embed debug symbols in the binary. And there's no way to override it because cmake is awful in every way.

Non-C++/C engineers that not every language enables you to vendor dependency so easy. There's to not just bundle every dependency.

I have been doing c++ and python programming for more than 10 years and still cout/print for debugging. Am I a bad person? Even for highly parallel applications I find printing out just is more natural to understand program flow.

Firstly, having so many C++ rules that the integer goes back to Zero, ouch. Secondly, you do realize that Palpatine was the one behind the droid army as well right? There was no need to send a programmer undercover, Count Doku could have just waved his hand and told the programmers working on the code to make sure the aiming code was bad and they'd do it without even realizing it. They'd probably go insane trying to find out why it was so bad all the time making sure it staid that way and never be any the wiser.

80%+ of learning c++ for me is package management and cmake. Oh my fucking god i wish these were better. Maybe theres a reason for them being like this but i dont even understand them well enough to see it

The good thing with C++ is that you can implement basically any paradigm. This is also why C++ sucks.

[@chigozie123]

It's like everyone and their sister who programs in C++ have simply given up on finding a good build system for C++, and instead find solace in telling each other that nothing good exists for managing dependencies.

In the time you get started with CMake set up CMake for cross plattform development with various differently organized dependencies, you could have already implemented your project if you subtract the time of CMake hassle

"OOP is not for games" screams chat, while unity is almost exclusively oop and even godot if you take into consideration that everything is a scene that has nodes in it with components inside. Everything is an object. If at least two of the most used engines do it, is not like it's a sin

[@TanigaDanae]

At ca. 14:00 regarding the reference to unique_ptr. I can imagine the author used the wrong words. "We wanted references to them" and "allowing us to append to the vector without risk of invalidating the references", they don't go hand in hand. Because references to unique_ptr can still be invalidated if you append to the vector. I suspect he was trying to express that he uses unique_ptr to hold the lifetime of the Object and uses the raw pointer of the unique_ptr to reference to it from somewhere else (avoiding the overhead of shared pointer). Edit: You can still not do that in Rust.

Don't really want to come back to C++ because of "The Rule of 5" and exceptions. Everything else is fine for me.

[@kodirovsshik]

Wdym "because of the rule of 5"? Your class either does resource management, in which case it is absolutely necessary to either implement the, you know, resource management or wrap your resources in RAII wrappers so that you don't ever have to deal with it, or your class doesn't do resource management - in which case you likely don't need the rule of 5. Like it's literally that simple. Want resource management? Yes - implement it, no - use wrappers and forget about it. What's the big deal for you?
