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.
