Function Library

Expose your own static methods to graphs as reusable, strongly-typed function nodes.

🛠️

Custom & Generic Nodes

Author custom and generic nodes plus editor views to fit any gameplay workflow.

Graph Tracker

Track and inspect live graph instances across your scene from a single window.

🐞

Live Debugging

Inspect execution paths, set breakpoints and debug ports right inside the editor.

Get Started

Install Ceres directly, then let the built-in Ceres Installer pull in the dependencies for you — no manual manifest.json editing required.

1

Add Ceres to your project

In Unity, open Package Manager → Add package from git URL and paste:

https://github.com/AkiKurisu/Ceres.git

Or clone the repo into your project's Packages/ folder.

2

Open the Ceres Installer

From the menu bar, choose Tools ▸ Ceres ▸ Installer.

3

Install dependencies

Click Install All to automatically download the required packages — Chris and UniTask. You're ready to build your first Flow graph.

The Ceres Installer resolves dependencies for you.

Prefer manual setup? Add these to your manifest.json instead:

"dependencies": {
  "com.kurisu.chris": "https://github.com/AkiKurisu/Chris.git",
  "com.cysharp.unitask": "https://github.com/Cysharp/UniTask.git?path=src/UniTask/Assets/Plugins/UniTask"
}

Requires Unity 2022.3 LTS or later — compatible with Unity 6.
