For this Unity Multiplayer Game Tutorial on how to make a multiplayer game in Unity with the Photon 2 Plugin, we will teach you how to spawn a player avatar or character. This will be an object that the players can control and use to play the game. This Avatar could be a person in a first-person shooter or a hero dungeon crawler RPG like Diablo 3. It is very important that you keep the Avatar as a sperate object the first photon network player object that is already spawned into the multiplayer scene.

We will begin by looking at how our game currently works. Our game currently has the Photon Player object that is the only object in our scene that is associated with our players because of this we need to make sure that we maintain this player object through the duration of our multiplayer game.

We will first create a new C# script in Unity we will call this C# script Photon Player. In this script, we need to include the Photon.PUN namespace we will then create some variable is this script including a Photon View variable. This script will be in charge of instantiating our player’s avatar object into the multiplayer scene.

In Unity, we need to create some empty game objects to be our spawn points transforms. We then need to create a player avatar prefab. We will need to set the variables of our scripts.

If you followed along with the video, you should have a working multiplayer game that allows you to instantiate new player avatar objects into the scene.

For this Unity Multiplayer Game Tutorial on how to make a multiplayer game in Unity using the Photon 2 plugin, we will be showing you how to create a Photon room controller script which will control some of the interactions between players connected to the same room. It will also control the start of the game and how the players are loaded into the multiplayer scene. There are two different ways to start a multiplayer game. One is a continuous load and the other is a delayed start. a continuous load means players can join and leave a game in progress at any time. whereas a delayed start is when all the players have to be connected to the room before the game can start. Our code in this video will handle both these methods and you will be able to switch between the two by changing a single bool.

We will start this lesson by creating two new C# scripts the first will be called Multiplayer Setting and the next one will be called Photon Room. We will then open these C# scripts up.

We will start in the Multiplayer Settings. We will first need to create some new variables. We can then delete the start and update functions. we will then create an awake function and set up a singleton for this C# script. We will then save this script after which we will make a few changes to our room creation in the lobby script.

We then need to open our Photon Room script. Inside this script, we will create some more variables. We will then create some code that will either load the player right into the multiplayer scene as soon as they connect to the room or the game will have a delayed start where all the players will load into the multiplayer scene at the same time. Once we have finished creating this script we will then save and return to Unity.

In Unity, we need to create an empty game object and attach our Photon room script. We will also create an empty game object and attach our multiplayer settings script. We then need to set the variable of these scripts. We will then create a placeholder for our Photon player object.

If you have followed along with the video tutorial you should then be able to build your project and run your multiplayer game, connect at least two instances of your game. This should then load your players into the multiplayer scene and you should be able to see the two players.

For this Unity Multiplayer Tutorial on how to make a multiplayer game in Unity, we will teach you how to make a connection to the photon Multiplayer servers. We will also teach you how to create methods by which players can either join existing rooms or create new ones if none are available. This is the basis for all multiplayer games. Before you get to networking the gameplay you first have to establish a connection between the players.

To get started in this lesson we will begin by creating a new C# script called PhotonLobby. This C# script will be responsible for setting up a connection to the Photon Multiplayer servers and creating new rooms. We will then open this C# script.

Inside this C# script, we will begin by creating a singleton of this C# script and object so that we can reference this C sharp script from other C# scripts. Next, we want to create some more variables for us to use in this C# script. In the start function, we want to establish a connection to the Photon Servers. This will require us to include the Photon.PUN namespace above. When we successful connect we want to enable a button for the players to click which will let them either create a new room or join an existing random room. We will first try to join a room and if we fail to join a room then we will try to create a new room.

Once you have finished creating this C sharp script you will need to save and return to Unity. In Unity, we will create a new empty object and then attach this Csharp script. We will then create two new buttons, one for the battle button and one for the cancel button. We will then set the variables of our Lobby C# script.

If you have followed the video about you should be able to make a build of your project and have multiple instances of your game connect to each other.
