How to get Unet to recognise rotation?

Question

When using Unet's default Network manager, Rotation of my sprites isn't synced.

I'm using the following manager setup: alt text

This is my Player object setup: alt text

How I'm rotating the sprite:

 void RLflip(int rflipcode){
         if (rflipcode != flipcode) {
             if(flipcode == 0){
                 transform.Rotate(new Vector3(0,180,0));
                 flipcode = 1;
             }else{
                 transform.Rotate(new Vector3(0,-180,0));
                 flipcode = 0;
             }
         }
     }

Any Ideas?

thanks in advance. Signed, Vandie.

Credit to @KaldrisRelm as without them I would never have figured this out. The script I ended up using was halfway fixed when they posted there final answer but it was based of their second comment.

At the top of my C# script I made sure that the following two variables where there:

     [SyncVar] private int flipcode;
     [SyncVar] private Quaternion SpriteRot;

I used the following code to flip all of the players on the server rather than the individual clients:

     [Command]void Cmd_RLflip(int rflipcode){
         if (rflipcode != flipcode) {
             if(flipcode == 0){
                 transform.Rotate(new Vector3(0,180,0));
                 flipcode = 1;
             }else{
                 transform.Rotate(new Vector3(0,-180,0));
                 flipcode = 0;
             }
             SpriteRot = transform.localRotation;
         }
     }

And then used one final method to sync it to the clients (which is called each Update) only when there has been a change in direction:

     void SyncRot(){
         if(!isServer && transform.localRotation != SpriteRot){
             transform.localRotation = SpriteRot;
         }
     }

Again this is a heavily fixed version of Kaldris's second comment so I thank them for the help.

Looking at the script you linked I see the problems:

You're setting the Vector3 SpriteRot to the transform.localRotation every update on the Server.
You're also using your RLflip only on the client, which won't transmit the details to the server to distribute.

To correct this you need to do the following:

Setup a Command to send a request to the Server to flip the Sprite when the player hits Left or Right

Remove the if(isServer) from your Control function
(Optionally) Remove the if(!isServer) from the UpdateRot function

Here's a quick script I built to Sync Rotation based on client input:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.Networking;
 
 public class RotationSync : NetworkBehaviour
 {
     [SyncVar(hook = "UpdateRot")] public Vector3 SpriteRot;
 
     void Update ()
     {
         if (isLocalPlayer)
         {
             Control();
         }
     }
 
     void Control()
     {
         if(Input.GetKey(KeyCode.RightArrow))
         {
             CmdFlip(false);
         }
         else if(Input.GetKey(KeyCode.LeftArrow))
         {
             CmdFlip(true);
         }
     }
     
     [Command]
     void CmdFlip(bool Flag)
     {
         if(Flag)
         {
             SpriteRot = new Vector3(-180,0,0);
         }
         else
         {
             SpriteRot = new Vector3(180,0,0);
         }
     }
     
     void UpdateRot(Vector3 NewPos)
     {
         transform.Rotate (NewPos);
     }
 }

As a side note, the above works on its own, you wouldn't want to use the Network Transform component.
