This is a repo of examples I've written to learn how to use the C# job system to write systems at scale, here for reference and sharing.

The goal of this repo is making it clearer how you can structure your data, schedule your jobs, and use the results. So, the examples use easy to understand problems & algorithms.

This doesn't (yet!) cover things related to using C# jobs with the upcoming Entity Component System.

Each example script has a corresponding scene where it's set up.

You can use the job system in the 2018.1 beta right now. Examples written here are written & tested on the latest beta version, starting with beta 4.

For a detailed look into how the C# job system works, please watch the Unite Austin presentation if you haven't seen it.

Note: examples in this repo use LateUpdate() as an easy way to handle completing jobs later than we schedule them, but in real code you might want to schedule the jobs early in Update (using Script Execution Order maybe) so you can use the result later in the same frame.

All examples demonstrate the use of persistently-allocated job memory.

Modify all 20678 vertices of a mesh in parallel every frame, using Perlin noise & sin(time).

Uses a single job.

Modify all vertices & normals of a mesh in parallel every frame.

This is the most visually interesting example. Uses a more complex single job.

First determine velocities, then change positions based on those velocities.

Demonstrates using the TransformAccessArray, necessary for doing transform operations in jobs.

Check a Vector3 and a Bounds for intersection against a list of 10000 Bounds.

Demonstrates running 2 independent jobs.

Check a Ray for intersection with a large Bounds array in two steps.

Demonstrates reducing an array of checks to a smaller list, and using temporarily-allocated job memory.

Generates a cloud of 10000 points, then calculates magnitudes & normalizes the points.
