Testing multiplayer sessions

Before we get into the weeds talking about how networking works, let's learn how to launch a multiplayer session. There are a number of ways you can do this. The easiest is to launch the multiplayer session directly from within your editor, and most of the time when you're testing network replication, this is going to be fine. For more comprehensive tests, or if you need one of the sessions to run in VR, you can launch two separate game sessions and connect them to each other. We'll show examples of how to do this a little later on when we discuss session types.

Testing multiplayer from the editor
