Creating a multiplayer game in Unity using Photon is a relatively straightforward process that can be completed in a few steps. Begin by opening Unity and selecting “Create New Project.” Next, select “3D” and click “Create Project.” Once the project is created, select “Assets” from the menu bar and click “Import Package” > “Custom Package.” Navigate to the Photon Unity Networking package you downloaded earlier and click “Open.” Once the package has been imported, you will need to create a new scene. To do this, select “File” from the menu bar and click “New Scene.” In the new scene, create two player objects. To do this, select “GameObject” from the menu bar and click “Create Empty.” Rename the first object “Player1” and the second object “Player2.” Next, add a Photon View component to each player object. To do this, select the player object and click “Add Component” > “Photon View.” Finally, add a Rigidbody component to each player object. To do this, select the player object and click “Add Component” > “Rigidbody.”
Once you have completed these steps, you will be able to test your multiplayer game by pressing the “Play” button in the Unity editor. Your two player objects will now be able to move around the scene and interact with each other over the network.
