Photon Unity Network (PUN) is our is our take on a Unity specific, high-level solution: Matchmaking, easy to use callbacks, components to synchronize GameObjects, Remote Procedure Calls (RPCs) and similar features provide a great start. Beyond that is a solid, extensive API for more advanced control.

Full source code is available, so you can scale this package to support any type of multiplayer game you come up with.

This package is compatible with the managed Photon Cloud service, which runs Photon Servers for you. A setup window registers you (for free) in less than a minute.

Documentation And Learning

There is an Online Documentation, which is considered a manual for PUN. This might become your primary source for information.

This is the Reference Documentation for PUN. It summarizes the most important classes in the Public API module and explains each class, method and field individually. This is generated from the source of PUN and should be used to look up details on usage and parameters.

Aside from that, there are also Demos in the PUN package itself and a PUN Basics Tutorial online, which you should check out.

First Steps

Import PUN into a new, empty project. Register via the pop up "wizard" (ALT+P) to get you a free Photon Cloud subscription (saving an initial AppId for you). Now you're ready to run and dissect the Demos.

Make sure to open and code the PUN Basics Tutorial.
