An easy to use Unity 3D library for creating illustrated Interactive Fiction games
Branch: master
Clone or download


The goal of Fungus is to provide a free, open source tool for creating interactive storytelling games in Unity 3D. Fungus is designed to be easy to learn for beginners to Unity 3D, especially for people with no coding experience. For power users, it provides an intuitive, fast workflow for visual scripting and interactive storytelling. Fungus is being used to create Visual Novels, Point and Click Adventure Games, Childrens Stories, Hidden Object Games, eLearning apps and also some frankly weird stuff which defies classification :)

Running the automated tests

The Unity Test Tools contains a tool called the Platform Runner which builds and runs all the test scenes automatically.

There is currently an issue with the Unity Test Tools on OSX that prevents the Platform Runner running all tests in the project. You can open each scene in the Tests folder individually and use the Unity Test Runner window to run all tests in the editor.

On Windows:

  1. Open the Platform Runner via Unity Test Tools > Platform Runner
  2. Select the platforms and tests you wish to run (defaults to running all).
  3. Run the tests and wait for the results. All tests should pass.
You can’t perform that action at this time.
