The goal of this lab is to get an introduction to building multi-player environments in Unity. The basic requirement for such an environment is a network connection over which the state of shared objects is synchronized. Luckily, Unity has recently revamped their networking support (since version 5) by providing super powerful high-level networking components. In this lab you get to assemble a couple of those components to make a fully working client/server structure.

You can start by browsing the Unity Manual: Multiplayer and Networking documentation.

Unlike previous labs, this one will rely on a networking tutorial provided by someone else. Christian Arellano has done an excellent job of putting together a Unity 5 Networking Tutorial in three parts on Gamasutra (which, by the way, is an excellent resource for game developers). For Lab 8, you only need to complete part 1:

• UNET Unity 5 Networking Tutorial Part 1 of 3 - Introducing the HLAPI

Everything you need is provided in the tutorial itself. If you are interested in the topic of networking, you can always move on to Part 2 of 3 as well (but Part 3 has not been published yet).
