Dialog System

Hyperbolica dev tells about the dialog system based on a custom noscripting language. He even created highlighting rules for Notepad++. Could be very convenient when dialogs are written and added to the game not by a programmer. You should consider time needed to create such system and amount of time you could save by removing the need in developer to integrate text assets.

Unity-Style-Guide: This article contains ideas for setting up a projects structure and naming convention for noscripts and assets in Unity

Can be used as a base for your own conventions. It also has a good quote: "Arguments over style are pointless. There should be a style guide, and you should follow it."

GitHub - asc-community/HonkPerf.NET

Benchmarks show it allocates less than standard LINQ. And the author claims on habr.com that it works great in Unity. Ideally should be benchmarked there too on IL2CPP build.

You might be thinking about shader performance wrong

Another rant on how memory access is slow, but has absolutely stunning animations quality, which the author made in Unity. Not really sure if this approach is faster than doing the same in some video editor, but definitely looks awesome

Create the ScriptableData data object if none is set (in the same folder as the prefab) extension for MonoBehaviour.
Use OdinInspector's [InlineEditor] attribute, to show the contents of the linked object in a Foldout.

Intro to Jobs/Burst/DoD.

How performance of a common MonoBehaviour approach can be improved by x200 with jobs and burst. Of course it's kind of artificial example, but on the large scale performance gains look awesome. And the author is a real "heavyweight" engineer from Unity, definitely worth checking his other posts.

Просто в теории, тяжело на деле

Determine if a point is inside a polygon. Author gives some solution, but I remember seeing Freya's tweet about using the winding number method, which I find to be better and cover more edge cases

Stalling a GPU

- Remember that a shader is more like a bunch of jobs than serial GPU code, even though the syntax looks like serial code
- Avoid introducing extra dependencies between those jobs, and understand the dependencies you have as they can hint to additional optimizations
- The cost of certain operations can be completely masked by this parallelism.
- The cost of all texture samples are not the same

How to unit test a class that uses static API

Unit tests validate code in isolation, but if it uses statics you cannot mock this dependency, therefore a subject under test cannot be properly isolated and unit tested. This trick makes the code testable, as well as introduces an important principle that improves your architecture by making it cleaner and more flexible.
