Unity3D

• Arguably the most popular game engine in the world
• Allows creation of 2D & 3D games, Virtual Reality, and Augmented Reality
• Programmed in C# or JavaScript

Unity3D & xAPI

• Rustici has a C# library for xAPI
• Unity3D has limitations:
• Doesn’t have the full C# functionality--specialized web functions
• Doesn’t completely support serialization--problems turning objects into JSON
• Work to adapt the Rustici library or come up with an alternative?
