• EntityComponentSystemSamples

  9 4,228 0.6 C#

  

  Project mention: EnTT: Gaming meets modern C++ 3.9 | news.ycombinator.com | 2021-12-21

  So you get cache locality as you're running through your transforms.

  Now imagine if instead of space invaders we're trying to model say blades of grass. Suddenly we go from a very cache unfriendly method to something that's cache friendly, branch prediction friendly, and easy to parallelize.

  If you want to experiment with it Unity has some great examples under their new DOTS system

  https://github.com/Unity-Technologies/EntityComponentSystemS...

  APIs can make data oriented more ergonomic than my contrived example implies, but it's still not nearly as intuitive as ECS imo.

  To me data oriented subsystems are fine, but not as a core concept for your game's architecture.

• ComputeSharp

  15 1,373 9.7 C#

  A .NET library to run C# code in parallel on the GPU through DX12 and dynamically generated HLSL compute shaders, with the goal of making GPU computing easy to use for all .NET developers! 🚀

  Project mention: What project are you currently working on? | reddit.com/r/csharp | 2022-01-09

  Outside of work, I spend most of my coding time working on ComputeSharp. It's a library that allows developers to run C# code on the GPU by automatically creating and compiling HLSL shaders (at build time or at runtime), and dispatching them using DirectX 12 API. It multi-targets .NET Standard 2.0 and .NET 6, so it pretty much runs anywhere on Windows (ie. from .NET Framework to UWP to .NET 6, and more), and I also have packages for UWP and WinUI 3 with built-in XAML controls to render shaders into an app. There's also a sample app in the Store! 😄

  Ultra fast and low latency asynchronous socket server & client C# .NET Core library with support TCP, SSL, UDP, HTTP, HTTPS, WebSocket protocols and 10K connections problem solution

  Project mention: Networking lib/framework for multiplayer servers ? | reddit.com/r/csharp | 2021-10-03

• Lazy Cache

  5 1,102 3.3 C#

  An easy to use thread safe in-memory caching service with a simple developer friendly API for c#

  Project mention: Parallel.ForEachAsync Deep Dive | reddit.com/r/dotnet | 2021-12-13

  I wasn't aware of this LazyCache nuget, it would requires a bit of a code rewrite for me to use directly, but it seems nice. The only issue is that I see their AsyncLazy implementation does not do what the stackoverflow post mention.

• BedrockFramework

  4 802 2.6 C#

  High performance, low level networking APIs for building custom servers and clients.

  Project mention: Sources for TCPClient and sockets programming | reddit.com/r/dotnet | 2021-12-18

  Sockets are best handled by a dedicated library. Another good tcp/socket library is Project Bedrock. It runs on top of kestrel, is very fast and stable.
