SyncVar - how to detect changes with get/set

Unity Engine
1

So, I’m sending some info to the server using a syncvar. No big deal. However, I like trigger events when a field changes. Like so:

private string _blah;

public string blah
{
      get { return _blah; }
      set
       {
                 if(value != _blah)
                  {
                          _blah = value;
                          OnBlahChanged(); // trigger the event handler
                  }
        }
}

But I’m not sure how to do that with SyncVars. I mean, I guess I could call two functions when I send the value to the server, like so:

[Command]
CmdSendToServer(string something)
{
      blah = something;
}

[Command]
CmdCheckIfBlahChanged()
{
     // do some previous / current checking here and then trigger events on the server side
}

This seems stupid and bad. There’s got to be a better way.

all you need is a hook attribute. The Unity docs should give an example, but I didn’t find it, so here you go:
