NativeArray2D

Tags: , , ,

Unity provides exactly one collection: NativeArray<T>. Compared to managed arrays in C#, these must be one-dimensional. So today we’re building a two-dimensional version of it: NativeArray<T>. We’ll add this to the NativeCollections GitHub repository for easy inclusion into any project. Read on to learn more about the collection!

Using Managed Types In Jobs

Tags: , ,

Job structs can’t contain managed types like string, class instances, or delegates. This is currently a pain as a lot of the Unity API relies on these and so we’re forced to deal with them. Today we’ll talk about how we can use managed types in our jobs to bridge the gap.

Simple Formula Evaluator Revisited

Tags: , , , , , ,

A couple years ago, I wrote an article showing how to empower game designers with the ability to write simple formulas like PlayerLevel*100+100. These are much more useful than just constants and don’t require any of the complexity of a real programming language. Today we’ll bring it into the Burst-compatible world and also improve its ability to handle more complex formulas.

Burst-Compiled Generic Algorithms

Tags: , , ,

Many algorithms get used over and over: searching, sorting, filtering, etc. C# makes these available with LINQ and functions like Array.Sort, but these can’t be compiled by Burst because interfaces and delegates aren’t supported. So how do we implement these generic algorithms to avoid re-writing them over and over? Today we’ll explore one technique to solve this problem. Read on to learn how!

P/Invoke in Burst: No Safety Net

Tags: , ,

Calling into native code like C++ from C# is a powerful interoperability tool in Unity. As we move more and more code out of Mono and IL2CPP and into Burst, will we still have this tool available? Today we’ll find out!
