Unity packages and demos—emphasizing ECS, jobs, and the Burst compiler—by me, Reese.


This project is a UPM package monorepo that supports the included demos, featuring:

  1. Nav - DOTS navigation with auto-jumping agents and movable surfaces.
  2. Spawning - Generic DOTS runtime spawning for any combination of prefab, components, and buffers.
  3. Randomization - Unity.Mathematics.Random number generators in jobs, including Burst-capable ones.

All of my packages are available on OpenUPM. Please support it and its maintainer, Favo. We depend on dedicated people like him.


My packages benefit from ubump, automating their SemVer-bumping needs, including committing, pushing, tagging, changelog generation and subtree splitting so each package can be released stand-alone and imported with OpenUPM or Git.

Here’s how my articles on relate to samples in this project:

DOTS Navigation with Auto-Jumping Agents and Movable Surfaces

The DOTS navigation scripts and demos are self-contained so you can use them in your project.

Linux & You

Linux users may need to do some extra work to get the project and/or packages up and running.

Mono Setup

Install Mono by following these directions.

Burst Prerequisite Setup

On Ubuntu I couldn’t use the Burst compiler until I manually installed gcc-multilib and libncurses5 with:

sudo apt install gcc-multilib libncurses5

You may have these libraries already, or you could be experiencing a different problem. Be sure to read any error messages the Unity Editor outputs.
