XNode
xNode is a Unity editor extension that provides a visual node graph editor for designing flow-based logic and state machines. It functions as a visual logic designer, allowing for the creation and management of interconnected node networks within the Unity engine.
The tool enables the construction of custom logic systems, such as branching dialogue trees and game state machine transitions. It supports the organization of complex graphs through a hierarchical grouping system that wraps related nodes into resizable visual containers.
The system utilizes a graph-based data model to define data flows and employs a canvas-based UI for interactive visualization. Connectivity and layout data are maintained using Unity's native serialization format.
