Unity角色多人同步

1.位置同步和状态同步：需要同步的节点上挂载脚本：

        gameObject.AddComponent<SyncTransform>(); ; //同步gameObject.GetComponent<SyncTransform>().syncId = SyncUtilFunc.GetRoleSyncId(PlayerData.Instance.PlayerId); //同步gameObject.GetComponent<SyncTransform>().ownerState = OwnerState.Mine;gameObject.GetComponent<SyncTransform>().isRole = true;gameObject.AddComponent<SyncState>(); //同步gameObject.GetComponent<SyncState>().syncId = SyncUtilFunc.GetRoleSyncId(PlayerData.Instance.PlayerId); //同步gameObject.GetComponent<SyncState>().ownerState = OwnerState.Mine;

（1）用于多人同步的基类：SyncBase.cs

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public enum OwnerState {Null,//无人拥有Mine,//拥有者是我Ohter,//拥有者是其他玩家
}public class SyncBase : MonoBehaviour
{/// <summary>/// 只有拥有者才允许发数据/// </summary>public OwnerState ownerState;public string syncId;public SyncWrapData dataBase = new SyncWrapData();protected string dataName;public void SendNetWork<T>(T data, string stName) {if (dataName != stName) {Debug.LogError("error:传输数据出错请检查" + dataName + " :" + stName);return;}dataBase.syncId = syncId;dataBase.name = dataName;dataBase.obj = JsonUtility.ToJson(data);dataBase.playerId = PlayerData.Instance.PlayerId.ToString();NetManager.Instance.SendSyncData(dataBase);}public void AddNetWorkListner<T>(Action<T> callback,string stName) {if (NetManager.Instance.isConnected() == false) {return;}dataName = stName;NetManager.Instance.AddSyncHandler(nameof(T), (SyncWrapData syncData) => {if (syncData.syncId == syncId) { //只关心自己同步ID的事情if (stName == syncData.name) {//类型结构需要和传递进来的结构一致var dstData = JsonUtility.FromJson<T>(syncData.obj); //ID一样自然可以转callback(dstData);}}});}}

引入库：LitJson

引用类：

public class SyncWrapData {public string syncId;public string playerId; //拥有者的IDpublic bool isLocation;public string name;public string obj;
}
