Project structure and a code walkthrough of the key game systems

Fusion Starter is an entry-level game sample for testing and learning Fusion and for playing multiplayer with friends and colleagues. It consists of three small independent examples, Third Person Character, Platformer and Shooter. The sample is aimed at beginners who have finished a Fusion tutorial and want to see Fusion best practices in a small project. All scripts are commented.

The sample ships as two Unity projects, a Shared Authority project where every client controls its own player and a Client Host project with client-side prediction and lag compensation, see Download.
