Client side don't work properly...

[sinful gulch]

changes to make:

    private void PlayerReadyUpdate(bool oldValue, bool newValue)
    {
        // This only fires on clients, including host client
        // Mirror has already set Ready to newValue
        LobbyController.Instance.UpdatePlayerList();
    }

    [Command]
    private void CmdSetPlayerReady()
    {
        // Change the SyncVar value
        Ready = !Ready;
    }

Sincerely thanks for the answer... But it don't fix my problem

You can see the situation here, I click the Ready button from left and it affect the right side but left one is still same

I wrote a log line for this sync hook function to see if client can get the call

But it seems like client side don't get the sync hook call

I launched the left side from Unity and launched the right side from builded application

Show inspector of whatever that script is on, with everything collapsed except that component

Sync Direction needs to be Server To Client
