It's incredibly useful in read-only, memory constrained scenarios. I.E. we used to mmap all of our animation data on many rendering engines I worked on where having ~20-50mb of animation data and only "paying" a couple 10s of

Oh you can totally get too cute with metatables. I've seen inheritance/straight-OO(Java/C++ style), component based design, and eventing/message based approaches all with the core primitives that Lua provides. I think my

It's not just that it's easy to embed but it's also tiny as well, I've run it on many embedded platforms. It wasn't until quickjs came along that there was anything even in the same ballpark. When you factor in Lua

Strong +1, RTL-SDR + rpi makes a great little platform. We have a couple weather/temp sensors from various brands and rtl_433 picks them in with no issues, throw all the data into Grafana/Influx and then visualize/export howe

That's actually one thing that I really like about Rust, since everything is static linkage by default it's easy to make pretty sweeping changes, on nightly you can even recompile the stdlib with different configurations(I.E. Oz&#

We kinda had that world with the PS3 and SPE/SPUs[1]. Stuff written for them tended to run faster on more traditional hardware since you needed to vectorize all of your loads(which made the prefetcher on other hardware really happy) bu

With the full caveat the CMake has to solve a design space that has a lot of legacy it still just makes a lot of unintuitive choices. I have to go look up the command line for generating vs building every single time I use it, and I've

Last game engine(C++) I worked on was a full hour to build if you touched a core header, and that was with Incredibuild that farmed out the compile across the studio. If you care about compile/iteration times you can get them down to a

At least on mobile SoCs that's exactly how it works, in fact due to how dynamic frequency scaling works it can be worse than 2x because to run at a higher frequency you need to run at a higher voltage. Your frequency increases(which

This was something that Microsoft did really well back in the Visual Studio days. That said Rust really raised the bar not just on tooling but the whole end-to-end experience and with cross-platform being table stakes now it really makes

std::shared_ptr says hello. IMO reference counting(be it in C, C++, Swift/ObjC or Rust) is a sign that you have ambiguous lifetimes and strongly correlates with a design that has punted on what components "own" what parts of

To take this even further, it's not the code that matters as much but the data access patterns and being able to have structured access patterns in ways that preserve cache locality. C# actually does really well on this front in that i

Git was better for everything except binaries, but if you could afford it Perforce did much better there. CVS though, uf da. We had some rough times in gamedev land until we moved over to SVN and then Perforce with proper proxies for a dist

There's broadly 2 types of state synchronization, lockstep and dead-reckoning. From the article it sounds like this is doing dead-reckoning where you let clients simulate locally and then resolve those differences on a continuous basis

Any engine can work, there are advantages with choosing engines that people build similar games with. I spent ~6mo "adding" core engine features(LoD streaming, etc) to a UE3 open-world title because most of the games on UE3 at the

Yeah Bevy does a fantastic job here(which given the focus on iteration time for gamedev makes sense). With the dynamic link feature it takes about 1s to compile + link and Bevy is very much a nontrivial runtime/library that makes use o

I feel like this was true a few years ago but things have changed a lot recently. In my opinion Bevy may be one of the better ECS implementations I've seen, as ex-gamedev it's just very well thought through. It's never going
