I tried to ‘Start’ creation of the image, and after reference
But it seems no effect, and did not get a reference
I can only get objects reference ‘Update’ in
What should I do to after the ‘Start’ or you can get a reference?

	[SyncVar]public int MyID;
	
	public GameObject P_body;
	public GameObject P_ind;
	
	public GameObject Mybody;
	public GameObject Myind;

	void Start () {
		transform.name = "PID"+GetComponent<NetworkIdentity>().netId;	//Give the player ID and rename
		MyID=int.Parse( GetComponent<NetworkIdentity>().netId.ToString() ) ;//Set Player ID
	}
	
	public override void OnStartLocalPlayer () {
		callobj();
	}

	public void FindMy(){
		Debug.Log (MyID+"BODY");
		Mybody = GameObject.Find(MyID+"BODY");
		Myind = GameObject.Find(MyID+"IND");
	}

	[Client]
	public void callobj(){
		Cmdcobj(transform.position);
	}
	
	[Command]
	public void Cmdcobj(Vector3 lp){
		lp+= new Vector3(0,20,0);
		GameObject nbody = (GameObject)Instantiate(P_body,lp,transform.rotation);
		nbody.GetComponent<BID>().myid = MyID;
		NetworkServer.Spawn(nbody);
		
		GameObject nind = (GameObject)Instantiate(P_ind,lp,transform.rotation);
		nind.GetComponent<BID>().myid = MyID;
		NetworkServer.Spawn(nind);
	}

I had a similiar problem. When the start method runs the id has not been set yet - its running before all the network bits have been set up. I’m grabbing the ID in an Update. You can always turn the script off when you’re done.

Create a event/listener system.

private NetworkIdentity networkIdentity = null;
private void Awake()
{
    networkIdentity = GetComponent<NetworkIdentity>();
    if(networkIdentity.IsIDReady == false){
        networkIdentity.OnIDReady += HandleOnIDReady;     
    }
    else{
        // Grab it as usual
    }
}
private void OnDestroy(){
    if(networkIdentity != null){
       networkIdentity.OnIDReady -= HandleOnIDReady;
       networkIdentity = null;
    }
}
private void HandleOnIDReady(string id){
    // Grab id as usual
    // And do what you got to do with it
}

Then the NetworkIdentity should implement the event:

public Action<string>OnIDReady = (str) => { };

private void MakeID(){
    string id = null;
    // Here the ID is made, Dunno how
    // ID is done
    OnIDReady(id);
}
