After working for about 1.5 years, I have decided to discontinue development of Egregoria.
Working on a big project alone, with little feedback and sparse rewards is hard.
The base gameplay loop needs a lot of features to be played: Advanced AI, Traffic system, Basic economy, Base building.

Even after so long, I am not even remotely close to the mvp.. And it's the easy part.

However I still count it all as a win, as I learned:

• To design highly efficient systems: Parallelization, cache efficiency and CPU architecture.
• To make a 3D engine using low level gpu interactions.
• A lot about computer graphics and why things look the way they do.
• Traffic systems and car interactions. Solving gridlocking was a great moment.
• Multiplayer/Networking using lockstep deterministic updates.
• Big project management: Egregoria totalling about 26k lines of Rust code.
• To design basic models in Blender.
• A bit about audio processing and how deep it can go.
• Road building: Lots of tricky graph shenaningans, one-off errors and complex geometry.
• Topological skeletons and other geometric algorithms.
• A bit about economy, what people do in their life.
• To use Github Actions for CI+CD.

I really liked working on this, publishing blogposts and videos of it to friends and followers online.
I will of course let the code online, if you are interested about games in Rust you might be want to see how I organized it, a good starting point is the Architecture.md file.

Thank you for following the project,
Goodbye!

Egregoria is a simulation of modern day society, from the bottom-up. Each individual has its own thought model, meaning every action has its importance and influences the environment.

An Egregor is an autonomous psychic entity made up of, and influencing, the thoughts of a group of people.
It represents emergence at its purest form, where individuals come together to become a collective force.

This is of course very ambitious, so a minimal viable product will be made where features are increasingly added.

The first milestone will introduce humans into the world. They will have their own homes and a workplace, traveling by foot or using the road system.

As of January 2021, this milestone is now achieved :-) I'm focusing on making more interesting interactions now, but I don't have the next milestone well-defined yet.

I keep a blog about Egregoria's development here.

This project uses Git LFS to track assets, therefore if you want to build your own copy you will need to install Git LFS.

Once installed, you should be able to clone the repo and fetch the assets:

git clone https://github.com/Uriopass/Egregoria
cd Egregoria
git lfs pull

I personally use Windows 10 and Mac OS 10.11, and it compiles fine once the rust toolchain is installed.

cargo run

There are a few libraries to install that some of my dependencies need:

sudo apt-get install libasound2-dev libudev-dev pkg-config libx11-dev
cargo run

A GitHub Action tests the builds on Ubuntu.

• @shika-blyat: For his work on the wgpu renderer
• @dabreegster: For inspiration on the map model
• @kosuru: For his wonderful ambient music
