The UNREAL Universe

Important

Verse, and UEFN and Fortnite and UE5 with a convergence of the tech upcoming in UE6 This started as a collection of all the information and links about Epic's Verse programming language, but since Verse is expected to converge into the general Unreal codebase in 2024 or 2025 the scope > of information found here will expand to be more useful to everyone in the Unreal Universe with the addition of information on Fortnite as well as the traditional Unreal UE5 ecosystem

Note

I can't believe it has been 2 months since the last update. This document is about 1/5 of the way to where I want it so incoming: more frequent updates

Tip

WHATS NEW: FAB.COM has replaced the Unreal Marketplace and it is a horrible sad replacement that is hard to navigate and make sense of for the PRIMARY PRIORITY of being useful to Unreal Developers. I will expand the FAB.COM section as we journey together to make sense out of that mess

This Document

Note

Most of the other various UNREAL lists of projects on GitHub point to a large number of old unmaintained projects. The extent of "CURATION" here is to eliminate things that won't work with Unreal 5.4, 5.5 and 6.0 and focus on the interesting and useful.

The document is organized by categories of

  • Unreal Programming Languages
    • Low level (C++, Verse)
    • High level (Blueprints, VisualVerse)
  • Extra Programming Languages
    • Python (Editor scripting)
    • Python (via Addon)
    • C# and F# (via Addon)
    • Lua (via Addon)
  • Important Companions such as Blender

There is also a "Type of Interest" set of categories that I hope to feature with a color code of some sort:

  • Background, History and Future Directions
  • A Learning path via Document Links
  • A Learning path via Video Tutorial Links
  • Quick Reference Links
  • Lists of Tools and Utilities
  • Lists of Plugins and Addons, both OSS/Free and recommended commercial
  • Samples, Examples and Full Featured Code
  • 3D and 2D Assets, both OSS/Free and recommended commercial
  • Pointers to other collections of Game Development info

Verse (UEFN, UE6)

"Verse is being designed as a programming language for the metaverse, with upcoming features to enable future scalability to vast open worlds built by millions of creators for billions of players. Verse is launching in Fortnite today, and will come to all Unreal Engine users a couple years down the road." https://www.unrealengine.com/en-US/blog/dive-into-epic-s-announcements-from-gdc-2023

Verse has been designed by Simon Peyton Jones and Tim Sweeney but very few people should start their Verse learning journey by examining the design.

Unreal Engine .NET (C#, F#)

  • Unreal Engine .NET 6 integration - UnrealCLR is a plugin which natively integrates .NET host into the Unreal Engine with the Common Language Runtime for direct execution of managed code to build a game/application logic using the full power of C# 10.0, F# 6.0, and .NET facilities with engine API. The project is aimed at stability, performance, and maintainability. https://github.com/nxrighthere/UnrealCLR
  • UnrealSharp attempts to add a dotnet core integration to some parts of Unreal Engine. It does this by creating what the dotnet documentation calls a "native host" in the context of a subsystem, and exposes functionality by providing function pointers to dotnet https://github.com/lambda-snail/UnrealSharp

Unfortunately, the only way to compile and run Verse programs is within the UEFN editing environment. (See below for a list of experimental Verses) Verse will eventually beccome standard in all versions of Unreal in order to provide increased security and massive scale, which is essential to supporting a MetaVerse.

Verse is supposed to be released as OSS at which point we might see a stand alone compiler which would really reduce one barrier to learning the language. You could then also envision from that a Jupyter compatible version that would encourage adhoc and online learning.

Delivering the first version of of Verse as Unreal Editor for Fortnite (UEFN) means that there are 3 sub systems of concern in making a Verse program:

Every Verse project generates 3 digest files that correspond to that

"The quaternions are members of a noncommutative division algebra first invented by William Rowan Hamilton. The idea for quaternions occurred to him while he was walking along the Royal Canal on his way to a meeting of the Irish Academy, and Hamilton was so pleased with his discovery that he scratched the fundamental formula of quaternion algebra, i^2=j^2=k^2=ijk=-1, into the stone of the Brougham bridge" - https://mathworld.wolfram.com/Quaternion.html

Misc Verse code on Github

  • STARS - if you have wandered to this repo wondering why I gave your project a STAR, well first a reward for uploading any Verse Code which is not common at all and second it makes easier for me to identify new projects with Verse...

This list is NOT curated but it might be useful to you since it is surprisingly hard to search for Verse code repos on Github due to name congestion (any topic with a -verse e.g. SpiderVerse) and the lack of a GitHub language type for Verse
