Unity PUN插件多人在线同步角色坐标旋转角度和动作

用PUN插件的话，就在OnJoinedRoom()回调函数里，表示加入房间，可以实例化角色，GameObject go=PhotonNetwork.Instantiate(prefabPlayer.name, new Vector3(241,0.2f,253), Quaternion.identity, 0);这里的prefabPlayer需要放在Resources文件夹里。

prefabPlayer上加上一个PhotonView组件，

为了同步在角色坐标，这里需要一个回调函数， void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info);在调用这个函数之前，需要做一点准备工作，因为这个函数我是写在PlayerPesonNetWork这个脚本里，所以需要把这脚本拖在PhotonView的Observed Components下，这样你就能在PlayerPesonNetWork脚本里的 void OnPhotonSerializeView(PhotonStream
stream, PhotonMessageInfo info);去写一些同步的信息。

这里我把PlayerPesonNetWork脚本粘出来：

using UnityEngine;
using System.Collections;
using Newtonsoft.Json;

public class PlayerPesonNetWork : Photon.MonoBehaviour
{
    GirlSniper girlSniper;
    public static PlayerPesonNetWork PPNW;
    void Awake()
    {
        girlSniper = GetComponent<GirlSniper>();
        if (photonView.isMine)
        {
            girlSniper.isControl = true;
            GameObject.Find("GameObjectMainCamera").GetComponent<MouseRotation>().target = gameObject.transform;
        }
        else
        {
            girlSniper.isControl = false;
        }
        gameObject.name = gameObject.name + photonView.viewID;
        PPNW = this;
    }
    void Start()
    {
    }

    void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
    {
        if (stream.isWriting)
        {
            //动作状态根据需求写的
            //将自己的动作状态 坐标 旋转角度传出
            stream.SendNext( JsonConvert.SerializeObject(girlSniper.animatorState_D));
            stream.SendNext(transform.position);
            stream.SendNext(transform.rotation);
        }
        else
        {
            //获取动作状态 坐标 旋转角度
            girlSniper.animatorState_D = JsonConvert.DeserializeObject <AnimatorState_D>((string)stream.ReceiveNext());
            correctPlayerPos = (Vector3)stream.ReceiveNext();
            correctPlayerRot = (Quaternion)stream.ReceiveNext();
        }
    }
    private Vector3 correctPlayerPos = Vector3.zero; //We lerp towards this
    private Quaternion correctPlayerRot = Quaternion.identity; //We lerp towards this

	// Update is called once per frame
	void Update () {

        if (!photonView.isMine)
        {
            transform.position = Vector3.Lerp(transform.position, correctPlayerPos, Time.deltaTime * 5);
            transform.rotation = Quaternion.Lerp(transform.rotation, correctPlayerRot, Time.deltaTime * 5);
        }
    }

}

同时我再把自己写的控制角色脚本也粘出来，这脚本也是绑在prefabPlayer上的：

using UnityEngine;
using System.Collections;

public class GirlSniper : MonoBehaviour {
    public Animator animator;
    private Camera cam;
    private UISprite spriteX;
    public bool isControl = true;
    public AnimatorState_D animatorState_D;
    private float playerSpeed = 2.0f;
    private GameObject goCameraParent;
   // public GameObject goShootAnimation;//开枪特效
	// Use this for initialization
	void Start () {
        goCameraParent = GameObject.Find("GameObjectMainCamera").gameObject;
        animator = GetComponent<Animator>();
        cam = Camera.main;
        spriteX = GameObject.Find("UI Root").transform.FindChild("Camera").FindChild("X").GetComponent<UISprite>();
        animatorState_D = new AnimatorState_D();

	}

	// Update is called once per frame
	void Update ()
    {
        if (animator)
        {
            if (!isControl)
            {
                enumUpdate();
            }
            else
            {
                isControlUpdate();
            }
        }
	}
    //控制更新
    void isControlUpdate()
    {
        float fVertical = Input.GetAxis("Vertical");
        float fHorizontal = Input.GetAxis("Horizontal");
        //当前的动画状态  参数0表示当前层级为0
        AnimatorStateInfo stateInfo = animator.GetCurrentAnimatorStateInfo(0);
        if (stateInfo.IsName("Base Layer.moveForward"))
        {
            if (Input.GetKeyDown(KeyCode.Space))
            {
                animator.SetBool("jump", true);
                animatorState_D.jump = true;
                transform.Translate(Vector3.forward * 2);
            }
            else if (Input.GetKeyUp(KeyCode.Space))
            {
                animator.SetBool("jump", false);
                animatorState_D.jump = false;
            }
        }

        if (stateInfo.IsName("Base Layer.idle"))
        {
            animator.SetBool("jump", Input.GetKeyDown(KeyCode.Space));
            animator.SetBool("happy", Input.GetKeyDown(KeyCode.H));
            animator.SetBool("sad", Input.GetKeyDown(KeyCode.U));

            animatorState_D.jump=Input.GetKeyDown(KeyCode.Space);
            animatorState_D.happy=Input.GetKeyDown(KeyCode.H);

        }
        if (stateInfo.IsName("Base Layer.idle_look"))
        {

        }
        if (Input.GetMouseButtonDown(0))
