前一篇文章已经介绍了弹幕的制作过程，然后服务器和客户端的交互不是很流畅，最近新学习了Unet，Unity自带的NetworkManager，使用这个实现的效果很不错，还可以发送中文啥的，先看下图：

先说下前半段吧，Unet的原理学习，我这里就不介绍了，看此教程钱先看下Unet的教程，不然后面的可能不太明白，具体的官网有教程：官方教程地址

然后再次基础上，我把之前做的弹幕放了进去，就是在此工程上放了一个预制Text,还有前篇的两个脚本，一个TextItem.cs，一个InputControl.cs脚本，稍作修改：

修改如下

最终的Hierachy面板如图所示：

InputField添加InputControl脚本和NetworkIdentity:

InputContol脚本的代码更新为如下：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.Networking;

public class InputControl : NetworkBehaviour
{
    /// <summary>
    /// text prefab
    /// </summary>
    public GameObject item;

    /// <summary>
    /// item的父物体
    /// </summary>
    public Transform parent;

    /// <summary>
    /// 输入框
    /// </summary>
    private InputField inputField;


    /// <summary>
    /// InputControl的单列
    /// </summary>
    public static InputControl Instance;

    /// <summary>
    /// 当前文本框的文字内容
    /// </summary>
    public static string currentText;

    // Use this for initialization
    void Start()
    {
        Instance = this;
        inputField = GetComponent<InputField>();
    }

    public void OnSumbit()
    {
        Debug.Log("===========1==============");
        currentText = inputField.text;
        PlayerController.Instance.CmdCreateItem(currentText);
        inputField.text = "";
        
        Debug.Log("===========2===============");
    }

    /// <summary>
    /// 实例化文本
    /// </summary>
    /// <param name="text">文本内容</param>
    /// <returns></returns>
    public GameObject CreateItem(string text)
    {
        Debug.Log("===========3===============");
        GameObject temp = Instantiate(item, parent) as GameObject;
        temp.GetComponent<TextItem>().contentText = text;

        return temp;
    }

}

TextItem脚本更新为：

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using UnityEngine.Networking;

public class TextItem : NetworkBehaviour
{
    public string text="&&&&&";

    private Text textAnchor;

    /// <summary>
    /// 同步文本内容
    /// </summary>
    [SyncVar(hook="OnChangeText")]
    public string contentText = "";

    void Start()
    {
        
        transform.SetParent(GameObject.FindGameObjectWithTag("UGUI").transform);

        textAnchor = GetComponent<Text>();

        textAnchor.text = contentText;
        textAnchor.color = Random.ColorHSV();
        float y = Random.Range(-200f, 220f);
        Debug.Log(y);
        
        transform.localPosition = new Vector3(550f, y, 0);
    }

    public float speed;

    void Update()
    {
        if (speed != 0)
        {
            float x = transform.localPosition.x + speed * Time.deltaTime;
            transform.localPosition = new Vector3(x, transform.localPosition.y, 1);

            //出屏幕销毁
            if (transform.localPosition.x < -550f)
            {
                Destroy(gameObject);
            }
        }
    }

    void OnChangeText(string text)
    {
        textAnchor = GetComponent<Text>();
        textAnchor.text = text;
    }
}

最后PlayerControl也需要更新下，具体原因，下面会具体详解：

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

public class PlayerController : NetworkBehaviour
{
    public GameObject bulletPrefab;
    public Transform bulletSpawn;

    public static PlayerController Instance;

    // Update is called once per frame
    void Update()
    {
        if (isLocalPlayer == false)
            return;



        float h = Input.GetAxis("Horizontal");
        float v = Input.GetAxis("Vertical");

        transform.Rotate(Vector3.up * h * 120 * Time.deltaTime);
        transform.Translate(Vector3.forward * v * 3 * Time.deltaTime);

        if (Input.GetKeyDown(KeyCode.Space))
        {
            CmdFire();
        }
    }

    public override void OnStartLocalPlayer()
    {
        Instance = this;
        //only worked on local role ,when the role was created
        GetComponent<MeshRenderer>().material.color = Color.blue;
    }

    [Command]//called in client ,run in server
    void CmdFire()//use by server
    {
        Debug.Log("+++++++++++++");
        //bullet should be born on server then Synchronise to other client
        GameObject bullet = Instantiate(bulletPrefab, bulletSpawn.position, bulletSpawn.rotation) as GameObject;
        bullet.GetComponent<Rigidbody>().velocity = bullet.transform.forward * 10;
        Destroy(bullet, 2);

        NetworkServer.Spawn(bullet);
    }

    [Command]
    public void CmdCreateItem(string text)
    {
        GameObject temp = InputControl.Instance.CreateItem(text);

        NetworkServer.Spawn(temp);
    }
}

到这里为止，你就会发现工程的客户端和服务器端可以交互的成功运行起来了，但是做到这个过程中遇到了很多问题，主要是两个问题解决的心得：
