Photon Server Deep Dive - View from Implmentation of PhotonWire, Multiplayer ...Yoshifumi Kawai
This document discusses PhotonWire, a framework for building networked games and applications. It allows clients and servers to communicate asynchronously using operations and operation requests/responses. Clients can send messages to servers using operations, which are received and handled via a switch statement based on operation code. Servers can then send response messages back to clients. The document also mentions plans to improve serialization performance in PhotonWire by replacing the current serializer.

How to make the Fastest C# Serializer, In the case of ZeroFormatterYoshifumi Kawai
The document discusses ZeroFormatter, an infinitely fast serializer that avoids common serialization inefficiencies. It provides benchmarks showing ZeroFormatter is faster than standard serializers. ZeroFormatter minimizes abstraction by directly writing to byte arrays without boxing or memory streams. Formatter classes handle different types by directly serializing/deserializing values without intermediate serialization steps. This achieves serialization with minimal overhead and memory allocation.
This document discusses using UniRx (Reactive Extensions for Unity) to make asynchronous network requests in a reactive and error-handling manner. Key points include:
1. Wrapping ObservableWWW requests in an ObservableClient to handle errors, timeouts, and retries in a consistent way across methods.
2. Using LINQ operators like Select, Catch, and Timeout to process the network response and handle errors in a reactive pipeline.
3. Implementing more complex retry logic by publishing and connecting an observable to retry requests automatically.
4. Combining multiple asynchronous requests using WhenAll to run them in parallel.
This document discusses RuntimeUnitTestToolkit, a tool for running unit tests on IL2CPP games. It allows creating unit test classes with public methods that will be automatically registered as tests. Tests can make assertions using the Is method and can be asynchronous by returning IEnumerator. It works with UniRx and allows testing asynchronous coroutines. The tool focuses on play time testing and supports running tests on actual devices.

The document discusses various methods for efficiently serializing and deserializing data in C# using MessagePack, including:
- Methods for reading primitive data types like integers and floats from bytes
- Representing float values as individual bytes for efficient serialization
- Using lookup tables and decoder interfaces to quickly determine MessagePack types and decode values
- Discussing faster alternatives like using direct memory copying instead of serialization delegates
- Mentioning how to extend MessagePack specifications while maintaining compatibility for faster serialization
A Brief History of UniRx/UniTask, IUniTaskSource in DepthYoshifumi Kawai
The document discusses the architecture of UniTask in C#, including the IUniTaskSource interface and AsyncUniTask class. IUniTaskSource defines methods for getting task results and status and handling completions. AsyncUniTask implements IUniTaskSource and manages a state machine and task pool for asynchronous operations. It retrieves tasks from the pool if available or creates new ones, and returns tasks to the pool after completion.
Deep Dive async/await in Unity with UniTask(EN)Yoshifumi Kawai
The document discusses asynchronous programming in C# using async/await and Rx. It explains that async/await is not truly asynchronous or multithreaded - it is for asynchronous code that runs on a single thread. UniTask is introduced as an alternative to Task that is optimized for Unity's single-threaded environment by avoiding overhead like ExecutionContext and SynchronizationContext. Async/await with UniTask provides better performance than coroutines or Rx observables for Unity.
Memory Management of C# with Unity Native CollectionsYoshifumi Kawai
This document discusses C# and memory management in Unity. It begins by introducing the author and some of their open-source projects related to C# and Unity, including libraries for serialization and reactive programming. It then discusses using async/await with Unity through the UniTask library. The document also covers differences in memory management between .NET Core and Unity due to using different runtimes (CoreCLR vs Unity runtime) and virtual machines. It presents examples of using unsafe code and pointers to directly manage memory in C# for cases like native collections. It concludes that while C# aims for a safe managed world, optimizations require bypassing the runtime through unsafe code, and being aware of memory can help better understand behavior and use APIs more

Reactive Extensions for JavaScript(RxJS)との接続
JavaScriptはEnumerableとObservableが両方そなわり
最強に見える
まあ、C#のほうがいいですけどね:)
LINQ to Everything, LINQ over the Language
RxJSはすっかり更新されてなくてアレゲだけど
更新待ってます
linq.jsも最後の更新が半年ぐらい前なのですけど
やるべきことは沢山たまっているのでやらないと……

Linq for Javascript + JQUERY == BLISS!
It's a totally bloody loop-buster!!!
A real time saver for JS intensive apps.
Can't even imagine writing JavaScript without this
library, linq.js together with jQuery makes life lot
easier;)
This library is an absolute requirement when doing
any JS coding - webpages, mongodb, node.js etc.
I've been using it for months and I can't live
without it.
