Ley Lines is a node graph editor framework for Unity that allows for a variety of uses.
For developers, Ley Lines simplifies the process of writing a specialized node graph editor. For example, a person writing a shader editor or an AI decision plugin can use this library to simplify the otherwise tedious process of writing the code to render a node graph in Unity.
The default configuration of Ley Lines allows developers and non-developers to quickly iterate and create simple run-time behaviours (ex. actions to take when a player enters a trigger volume). This framework also allows for the sequencing of events, which is typically time-consuming to create manually.
The overall advantage of this framework is to open up Unity to allow artists and level designers to create simple behaviours without programmer intervention.
