Multiplayer Networking - Player Cameras issue

Unity Engine
1

Hello, I’m working on a personal project right now to learn Unity. I started using Unity around 2 months ago, and I’ve been having some issues getting cameras and such working.

The game is intended to be a 3D flight shooter which as of right now uses mouse aim and WASD to move. Local singleplayer works, However, upon adding more clients (or making a server, then joining as a client), things get wonky.

Camera focus for EVERY player jumps to the last player that joined, despite each player not losing any actual control.

Additionally, I had a problem where bullet shots fired by the player only followed the direction the player was facing if they were the host. I did find a way to remedy this by making the shot prefab have a high network send rate, but I feel like this just bogs down the system and was wondering if there was a better way to do it.

Here’s some of the code I have so far, bear in mind I am still very much a novice at this:

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class MouseAimCamera : NetworkBehaviour {
    public GameObject target;
    public float rotateSpeed = 5;

    void Start() {
            transform.parent = target.transform;
            //transform.LookAt (target.transform);
    }

    void LateUpdate() {
            float horizontal = Input.GetAxis ("Mouse X") * rotateSpeed;
            float vertical = Input.GetAxis ("Mouse Y") * rotateSpeed;
            target.transform.Rotate (-vertical, horizontal, 0);

    }

}

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class ClientCam : NetworkBehaviour {
    [SerializeField]
    public Camera cam;

    public override void OnStartClient() {
        // Make sure mouse aim knows we're looking at the local player
        cam.GetComponent<MouseAimCamera>().target = gameObject;
        // Place camera behind player
        Vector3 pos = new Vector3 (transform.position.x+0.1f, transform.position.y + 0.9f, transform.position.z - 4.1f);
        Instantiate (cam, pos, transform.rotation);
            cam.enabled = true;
        }
    }

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class Done_PlayerController : NetworkBehaviour
{
    public float speed;
    public float turnrt;
    public float maxSpeed;
    public GameObject shotPrefab;
    public Transform shotSpawn;
    public float fireRate;
    
    private float nextFire;
   
    void Update ()
    {
        if (!isLocalPlayer) {
            // This is not the local player, exit.
            return;
        } else {
            if (Input.GetButton ("Fire1") && Time.time > nextFire) {
                nextFire = Time.time + fireRate;
                CmdFire ();
            }
        }
    }

    void FixedUpdate ()
    {
        if (!isLocalPlayer) {
            return;
        } else {
           
            float moveHorizontal = Input.GetAxis ("Horizontal");
            float moveVertical = Input.GetAxis ("Vertical");

            if (moveVertical != 0) { // Moving forward
                GetComponent<Rigidbody> ().AddRelativeForce (Vector3.forward * (moveVertical * speed));
            }
            if (moveHorizontal != 0) { // Strafing
                GetComponent<Rigidbody> ().AddRelativeForce (Vector3.right * (moveHorizontal * (speed*1.7f)));
            }

            if (GetComponent<Rigidbody> ().velocity.magnitude > maxSpeed) { // Set speed cap so we dont move too fast
                GetComponent<Rigidbody> ().velocity = GetComponent<Rigidbody> ().velocity.normalized * maxSpeed;
            }
        }
   
    }
   
    [Command]
    void CmdFire() {
        GameObject shot = (GameObject) Instantiate (shotPrefab, shotSpawn.position, shotSpawn.rotation);
        GetComponent<AudioSource> ().Play ();

        NetworkServer.Spawn (shot);
        Destroy (shot, 3.0f);
    }
}

Any help would be greatly appreciated.

Nevermind, I just fixed it by changing the ClientCam code to this:

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;

public class ClientCam : NetworkBehaviour {
    [SerializeField]
    public Camera cam;

    public override void OnStartLocalPlayer() {
        if (!isLocalPlayer) {
            return;
        }
        cam.GetComponent<MouseAimCamera>().target = gameObject;
        Vector3 pos = new Vector3 (transform.position.x+0.1f, transform.position.y + 0.9f, transform.position.z - 4.1f);
        Instantiate (cam, pos, transform.rotation);
            cam.enabled = true;
        }
    }

Simple fix took me 5 hours to figure out. Insert your choice of profanity.
