Unity Multiplayer – Code Matchmaking

For this lesson, we will teach you how to create a code matchmaking system for the Photon Pun 2 plugin in Unity. This system allows players to create a room that will give them a room code. They can then share the code with their friend so their friends can then join the same room. Code matchmaking can be found in a number of popular games like Random Dice. Code matchmaking is a good way to play games with friends if your game does not have friends or party mechanics.

PUN 2 in Unity: Make a Game Multiplayer Lesson 8

For this lesson on how to make your games multiplayer with Photon PUN in Unity, We will be adding the ability for the players to type in a username. We will then use that username and sync it across the network so that you can see both players’ names. To get started you will first want to add a UI InputField to your QuickStart UI canvas. You can then position and resize this object to fit your liking.

Canvas
- QuickStartMenu
  - Title
  - Loading
  - QuickStart
  - QuickCancel
  - – Add the default UI input field object and customize it as you wish.

Next, we need to create a function that we can pair to this input field so we will open up the MainMenuController script. Inside this script first, add the Photon.PUN namespace. Then create a new public function with a string parameter. Then inside this function set the Photon NickName variable to the string parameter. After which you can then save this script and go back to Unity. Inside Unity, you will need to OnEndEdit event of your object to be this new public function that we just created.

Now that we are reading in and setting the player’s name we can use it in our game. To do this first go to the GameController script. inside this script, we need to add two new Text variables. The first can be called myName and the second can be called theirName. To set this string value of the myName variable, create a Start function. Then inside the start set the string value to the NickName photon variable.

From here we then want to create a public function to set the other player’s name when we receive it. This function could be called SetTheirName and it should have one string parameter. Inside this function just set the string value of the theirName variable to the parameter. Now save this script and go to the PaddleController script.

Inside the PaddleController script, we need to create a networked RPC function that will send the local player’s name to the other client. Go ahead and create an RPC function with one parameter of type string. Then inside this function use the singleton of the GameController script to call the SetTheirName function and pass in the parameter. Finally, we need to call this RPC function and we will do that with the Start function right have we rotate the camera. You should call the RPC function within the if statement checking if the local player owns this object. The RPC function should be sent to OthersBufferd and the parameter value should be then local player’s Photon NickName. Now save this script and return to Unity.

Inside Unity, you will need to set the two new variables we create. For these, you can set them to the Player1Keys and Player2Keys objects that we already have from this pong project. We can do this because we no longer need to displayer the controls to the players and they are always the same. You might also want to reposition these objects if necessary.

Now you should have the ability to test your project. You should be able to see the different player’s names on both clients. The local player’s name should be at the bottom of the screen and the other player’s should be at the top

PUN 2 in Unity: Make a Game Multiplayer Lesson 7

For this lesson on how to make your games multiplayer with Photon PUN in Unity, We will show you how to disconnect for a connected room which will complete our gameplay loop. To do this we want to open up the game controller script inside the script we first need to add the Photon PUN namespace at the top.

Now inside the class, there are two ways that the players can load back to the main menu seen the first is in the update function where we have this if statement where we check for the player’s input when they press the Escape key. Inside this, if statement before we load back to the main menu scene you will want to call the LeaveRoom function.

Now, scroll down where we have this public function called MainMenu, This function is pair the button on our GameOverPanel. Once again before we load to the main menu scene make sure you call the LeaveRoom function.

Now save your script and go back to Unity and test it out.
