CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

// When creating shaders for Universal Render Pipeline you can you the ShaderGraph which is super AWESOME!
// However, if you want to author shaders in shading language you can use this teamplate as a base.
// Please note, this shader does not necessarily match perfomance of the built-in URP Lit shader.
// This shader works with URP 7.1.x and above

This is a partial C# implementation of UnityEngine.Random with (almost) 1-to-1 parity.

Unity uses Xorshift for psuedorandom number generation. In particular Xorshift128, which uses a state consisting of four unsigned 32-bit integer values. The state is initialized in UnityEngine.Random.InitState using a signed 32-bit integer seed, which is shuffled around with a technique similar to the way a Mersenne Twister is initialized.

This has been tested as far back as Unity 4.7.0f1, and as recent as Unity 2020.1.17f1.

Notes

• Huge thanks to MoatShrimp for figuring out how Unity initializes the Xorshift state parameters in InitState, and floating point generation.
• C# - As below. Values may differ in .NET 5.0, but thankfully Unity doesn't yet support that.
• JavaScript - Check out MoatShrimp's JS implemention (and neat Undermine loot lookup tool) here:
