Needing Help With Multiplayer Camera System

Hey so I am making a game with one Player prefab that clones itself for each player joined, the ball also has a camera that follows it but the problem I have is that it will follow the host but not the client, here is my script:

 void LateUpdate()
        {
            // Find the player's ball based on ownership
            if (NetworkManager.Singleton != null && NetworkManager.Singleton.ConnectedClients.TryGetValue(NetworkManager.Singleton.LocalClientId, out var networkClient))
            {
                var playerNetwork = networkClient.PlayerObject.GetComponent<PlayerNetwork>();
                if (playerNetwork != null)
                {
                    CameraTarget = playerNetwork.BallTransform;
                }
            }

            // Check if we still have a valid target
            if (CameraTarget != null)
            {
                if (CameraMode == CameraModes.Follow)
                {
                    // Get the player's network script if it's available
                    playerNetwork = CameraTarget.GetComponent<PlayerNetwork>();

                    // Update desired position based on player's ball transform
                    if (playerNetwork != null)
                    {
                        desiredPosition = playerNetwork.BallTransform.position + Quaternion.Euler(ElevationAngle, OrbitalAngle, 0f) * new Vector3(0, 0, -FollowDistance);
                    }
                }
                else if (CameraMode == CameraModes.Isometric)
                {
                    desiredPosition = CameraTarget.position + Quaternion.Euler(ElevationAngle, OrbitalAngle, 0f) * new Vector3(0, 0, -FollowDistance);
                }
                else
                {
                    // Free Camera implementation
                }

                if (MovementSmoothing == true)
                {
                    cameraTransform.position = Vector3.SmoothDamp(cameraTransform.position, desiredPosition, ref currentVelocity, MovementSmoothingValue * Time.fixedDeltaTime);
                }
                else
                {
                    cameraTransform.position = desiredPosition;
                }

                if (RotationSmoothing == true)
                    cameraTransform.rotation = Quaternion.Lerp(cameraTransform.rotation, Quaternion.LookRotation(CameraTarget.position - cameraTransform.position), RotationSmoothingValue * Time.deltaTime);
                else
                {
                    cameraTransform.LookAt(CameraTarget);
                }
            }

            GetPlayerInput();

            // Find the player ball with the name "Player(Clone)"
            GameObject playerBall = GameObject.Find("Player(Clone)");

            // Check if we found the player ball
            if (playerBall != null)
            {
                // Set the player ball as the CameraTarget
                CameraTarget = playerBall.transform;

                if (CameraMode == CameraModes.Isometric)
                {
                    desiredPosition = CameraTarget.position + Quaternion.Euler(ElevationAngle, OrbitalAngle, 0f) * new Vector3(0, 0, -FollowDistance);
                }
                else if (CameraMode == CameraModes.Follow)
                {
                    desiredPosition = CameraTarget.position + CameraTarget.TransformDirection(Quaternion.Euler(ElevationAngle, OrbitalAngle, 0f) * (new Vector3(0, 0, -FollowDistance)));
                }
                else
                {
                    // Free Camera implementation
                }

                if (MovementSmoothing == true)
                {
                    cameraTransform.position = Vector3.SmoothDamp(cameraTransform.position, desiredPosition, ref currentVelocity, MovementSmoothingValue * Time.fixedDeltaTime);
                }
                else
                {
                    cameraTransform.position = desiredPosition;
                }

                if (RotationSmoothing == true)
                    cameraTransform.rotation = Quaternion.Lerp(cameraTransform.rotation, Quaternion.LookRotation(CameraTarget.position - cameraTransform.position), RotationSmoothingValue * Time.deltaTime);
                else
                {
                    cameraTransform.LookAt(CameraTarget);
                }
            }
        }

I also have another problem, the host ball moves normal but when a client joins it is super fast. Please let me know why this is happening.

I know this is the worst answer possible, but if you cant figure it out, consider switching to FishNet, it has a huge community with good docs and people willing to help/answer questions on their discord.

Here is how you can find out what is happening in your project. Remember, it’s probably not just the code.

Time to start debugging! Here is how you can begin your exciting new debugging adventures:

You must find a way to get the information you need in order to reason about what the problem is.

Once you understand what the problem is, you may begin to reason about a solution to the problem.

What is often happening in these cases is one of the following:

  • the code you think is executing is not actually executing at all
  • the code is executing far EARLIER or LATER than you think
  • the code is executing far LESS OFTEN than you think
  • the code is executing far MORE OFTEN than you think
  • the code is executing on another GameObject than you think it is
  • you’re getting an error or warning and you haven’t noticed it in the console window

To help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

  • is this code even running? which parts are running? how often does it run? what order does it run in?
  • what are the names of the GameObjects or Components involved?
  • what are the values of the variables involved? Are they initialized? Are the values reasonable?
  • are you meeting ALL the requirements to receive callbacks such as triggers / colliders (review the documentation)

Knowing this information will help you reason about the behavior you are seeing.

You can also supply a second argument to Debug.Log() and when you click the message, it will highlight the object in scene, such as Debug.Log("Problem!",this);

If your problem would benefit from in-scene or in-game visualization, Debug.DrawRay() or Debug.DrawLine() can help you visualize things like rays (used in raycasting) or distances.

You can also call Debug.Break() to pause the Editor when certain interesting pieces of code run, and then study the scene manually, looking for all the parts, where they are, what scripts are on them, etc.

You can also call GameObject.CreatePrimitive() to emplace debug-marker-ish objects in the scene at runtime.

You could also just display various important quantities in UI Text elements to watch them change as you play the game.

Visit Google for how to see console output from builds. If you are running a mobile device you can also view the console output. Google for how on your particular mobile target, such as this answer for iOS: https://discussions.unity.com/t/700551 or this answer for Android: https://discussions.unity.com/t/699654

If you are working in VR, it might be useful to make your on onscreen log output, or integrate one from the asset store, so you can see what is happening as you operate your software.

Another useful approach is to temporarily strip out everything besides what is necessary to prove your issue. This can simplify and isolate compounding effects of other items in your scene or prefab.

If your problem is with OnCollision-type functions, print the name of what is passed in!

Here’s an example of putting in a laser-focused Debug.Log() and how that can save you a TON of time wallowing around speculating what might be going wrong:

Note: the print() function is an alias for Debug.Log() provided by the MonoBehaviour class.


Once you get the right object to follow nailed down, consider this:

Camera stuff is pretty tricky… you may wish to consider using Cinemachine from the Unity Package Manager.
