Visual Scripting in Unity: A Comparative Analysis of Existing Frameworks

This paper explores the use of visual scripting languages in game engines, particularly in Unity, comparing different third-party frameworks. The typical applications of visual scripting in games are examined and compared, including dialog, Non-Playable Character behavior, camera movement, and more. Unity's built-in visual scripting tool, formerly Bolt, is examined in detail and compared to various third-party commercial frameworks such as Node Canvas, Playmaker, Behavior Designer and Flow Canvas.
