Chapter 2. Photon Unity Networking – The Chat Client
In the last chapter, we reviewed the Unity Networking API provided with the Unity game engine. In this chapter, we will review an alternative to Unity Networking, called Photon Unity Networking (PUN).
In this chapter, we will cover:
- How PUN works
- The differences and similarities between PUN and Unity Networking
- Setting up PUN with Photon Cloud
- Using PhotonViews
- Connecting to Photon
- Getting a list of rooms
- Creating and joining rooms
- Filtering lobby results by preference
- Automatic matchmaking
- Using FindFriends
- Syncing a level between players
