Packages for Unity 6 and HDRP, each in its own git repository, for runtime systems, editor tools, rendering, the environment, humanoid characters and UI Toolkit. This package, com.unityessentials.core, adds an editor window that lists the packages of the EggyStudio account and installs the ones selected, together with the packages they depend on.

All scripts are contained within the UnityEssentials namespace.

1. Add the package via Unity's Package Manager

   • Window → Package Manager → "+" → "Add package from git URL…"
   • Paste the following:

   https://github.com/EggyStudio/UnityEssentials.git
   

2. Install modules from the Tools menu

   • Tools → UnityEssentials → Install & Update
   • Select individual modules or install all; run again anytime to update

Dependencies between modules are resolved automatically.

Tools → UnityEssentials → Initialize Addressables creates the project's Addressables settings, which several packages load their assets from. The package does the same after each script reload.

A package marked not implemented holds only its manifest and assembly definition, and installs without adding any code.
