Unity3D конвертирует простую рекурсивную игру змея в многопользовательскую игру змея

Question

М новый в UNET. Я хочу превратить простую рекурсивную игру змея в многопользовательскую игру змея. Это мой код SnakeHead:

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

public class SnakeHead : NetworkBehaviour {
    [SyncVar]
    public string playerName = "Player";
    [SyncVar]
    public Color playerColor = Color.white;
    private int maxSize;
    [SyncVar]
    private int currentSize = 0;
    private int NESW;
    private Vector2 nextPos;
    private Vector2 currentPos;
    private float currentDeltaTimer;
    private float minDeltaTimer = 0.05f;
    private float maxDeltaTimer = 0.2f;
    private float stepDeltaTimer = 0.2f;
    public GameObject snakeTailPrefab;
    private SnakeTail snakeTail;
    private Vector2 touchOrigin = -Vector2.one;
    public int xBound = 40;
    public int yBound = 40;

    public override void OnStartLocalPlayer () {
        currentDeltaTimer = maxDeltaTimer;
        InvokeRepeating ("TimerInvoke", 0, currentDeltaTimer);
    }

    void Start () {
        GameObject snakeHolder = new GameObject ("Snake_"+playerName);
        snakeHolder.transform.position = Vector3.zero;
        transform.parent = snakeHolder.transform;
        GetComponent<MeshRenderer>().material.color = playerColor;
    }
    void Update () {
        if (!isLocalPlayer) {
            return;
        }
        if (Input.touchCount > 0)
        {
            Touch myTouch = Input.touches[0];
            if (myTouch.phase == TouchPhase.Began)
            {
                touchOrigin = myTouch.position;
            }
            else if (myTouch.phase == TouchPhase.Ended && touchOrigin.x >= 0)
            {
                Vector2 touchEnd = myTouch.position;
                float x = touchEnd.x - touchOrigin.x;
                float y = touchEnd.y - touchOrigin.y;
                touchOrigin.x = -1;
                if (Mathf.Abs (x) > Mathf.Abs (y)) {
                    if (x > 0) {
                        MobileChangeDirection(1);
                    } else {
                        MobileChangeDirection(3);
                    }
                } else {
                    if (y > 0) {
                        MobileChangeDirection(0);
                    } else {
                        MobileChangeDirection(2);
                    }
                }
            }
        }
    }

    private void Movement(){
        currentPos = transform.position;
        switch (NESW) {
        case 0:
            nextPos = new Vector2 (currentPos.x, currentPos.y + 1);
            break;
        case 1:
            nextPos = new Vector2 (currentPos.x + 1, currentPos.y);
            break;
        case 2:
            nextPos = new Vector2 (currentPos.x, currentPos.y - 1);
            break;
        case 3:
            nextPos = new Vector2 (currentPos.x - 1, currentPos.y);
            break;
        }
        transform.position = nextPos;
        if (!snakeTail) {
            currentSize++;
            GameObject tempTail = (GameObject)Instantiate (snakeTailPrefab, nextPos, transform.rotation);
            snakeTail = tempTail.GetComponent<SnakeTail>();
            tempTail.name = "SnakeTrail (" + currentSize + ")";
            snakeTail.FixParent (transform.parent);
            tempTail.GetComponent<MeshRenderer>().material.color = playerColor;
            NetworkServer.Spawn (tempTail);
        }
        snakeTail.Movement (currentPos);
    }

    void TimerInvoke(){
        Movement ();
        StartCoroutine (CheckVisible());
    }

    public void MobileChangeDirection(int swipeDirection){
        if (NESW != 2 && swipeDirection == 0) {
            NESW = swipeDirection;
        }else if (NESW != 3 && swipeDirection == 1) {
            NESW = swipeDirection;
        }else if (NESW != 0 && swipeDirection == 2) {
            NESW = swipeDirection;
        }else if (NESW != 1 && swipeDirection == 3) {
            NESW = swipeDirection;
        }
    }

    void OnTriggerEnter (Collider other){
        if (other.CompareTag ("Food")) {
            EatFood ();
            Destroy (other.gameObject);
        }else if (other.CompareTag("SnakeTail")) {

        }
}

    public void EatFood(){
        if (snakeTail) {
            currentSize++;
            snakeTail.EatFood (currentSize, playerColor);
        }
    }

    void Wrap(){
        if(NESW == 0){
            transform.position = new Vector2 (transform.position.x, -(transform.position.y - 1));
        }else if(NESW == 1){
            transform.position = new Vector2 (-(transform.position.x - 1), transform.position.y);
        }else if(NESW == 2){
        transform.position = new Vector2 (transform.position.x, -(transform.position.y + 1));
        }else if(NESW == 3){
            transform.position = new Vector2 (-(transform.position.x + 1), transform.position.y);
        }
     }


    IEnumerator CheckVisible(){
        yield return new WaitForEndOfFrame ();
        if(!IsInGameArea()){
            Wrap ();
        }
    }

    private bool IsInGameArea(){
        Vector3 pos = transform.position;
        if(pos.x >= -xBound && pos.x <= xBound && pos.y >= -yBound && pos.y <= yBound){
            return true;
        }
        return false;
    }
}

и это мой код SnakeTail:

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

public class SnakeTail : NetworkBehaviour {
    private Vector2 currentPos;
    public GameObject snakeTailPrefab;
    private SnakeTail snakeTail;
    public void Movement(Vector2 nextPos){
        currentPos = transform.position;
        if(snakeTail){
            snakeTail.Movement (currentPos);
        }
        transform.position = nextPos;
    }
    public void FixParent(Transform snakeTransform){
        transform.parent = snakeTransform;
    }
    public void EatFood(int currentSize, Color playerColor){
        if (!snakeTail) {
            GameObject tempTail = (GameObject)Instantiate (snakeTailPrefab, transform.position, transform.rotation);
            tempTail.name = "SnakeTrail (" + currentSize + ")";
            snakeTail = tempTail.GetComponent<SnakeTail> ();
            snakeTail.FixParent (transform.parent);
            tempTail.GetComponent<MeshRenderer>().material.color = playerColor;
            NetworkServer.Spawn (tempTail);
        } else {
            snakeTail.EatFood (currentSize, playerColor);
        }
    }
}

Я создаю SnakeHead и SnakeTail GameObject Prefab с NetworkIdentity (локальный игрок проверен) и NetworkTransform. SnakeHead GameObject - это мой "Префаб игрока", а SnakeTail - "Зарегистрированный порожденный префаб" в моем NetworkManager. Когда два устройства соединяются друг с другом и играют в игру, SnakeTail не добавляет в Player на хост-устройстве и цвет SnakeTail не меняется на устройстве RemoteClient. Как я могу это исправить?
