1.下载资源包 

2.配置NetworkManager

（1）在Assets/Prefabs下创建Network Prefabs List

相应设置如下： 

（2） 创建空物体“NetworkManager”并挂载NetworkManager组件。相应设置如下：

（3） 选择Player预制体并挂载组件Network Object

（4）在Asset/Scripts/目录下创建Network目录并创建并编写ClientNetworkTransform.cs，使Client可控制transform的属性，将其挂载至Player预制体

using Unity.Netcode.Components;
using UnityEngine;

namespace Unity.Multiplayer.Samples.Utilities.ClientAuthority
{
    [DisallowMultipleComponent]
    public class ClientNetworkTransform : NetworkTransform
    {
        protected override bool OnIsServerAuthoritative()
        {
            return false;
        }
    }
}

并进行如下设置

（5） 选择Player预制体并挂载组件Network Rigidbody

（6）将原有的Main Camera重命名（F2）为SceneCamera，并将其Tag设置为MainCamera

（7）在Player预制体上创建并编写PlayerSetup.cs，使游戏只接收本地输入

using UnityEngine;
using Unity.Netcode;

public class PlayerSetup : NetworkBehaviour
{
    [SerializeField] 
    private Behaviour[] componentsToDisable;
    [SerializeField] 
    private Camera sceneCamera;
    
    // Start is called before the first frame update
    void Start()
    {
        if (!IsLocalPlayer)
        {
            for (int i = 0; i < componentsToDisable.Length; i++)
            {
                componentsToDisable[i].enabled = false;
            }
        }
        else
        {
            sceneCamera=Camera.main;
            if (Camera.main != null)
            {
                sceneCamera.gameObject.SetActive(false);
            }
        }
    }

    private void OnDisable()
    {
        sceneCamera.gameObject.SetActive(true);
    }
}

 并对其进行如下设置

将其移动至Assets/Scripts/Player目录下 

3.编写测试UI

（1）创建Canvas并将其命名为MenuUI，并在其内部创建3个Button并分别命名为Host，Server以及Client。Hierarchy中的物体结构和UI布局如下：

 

（2）在NetworkManager上创建并编写NetworkManageUI.cs，编写按钮逻辑

using Unity.Netcode;
using UnityEngine;
using UnityEngine.UI;

public class NetworkManagerUI : MonoBehaviour
{
    [SerializeField] 
    private Button hostBtn;
    [SerializeField] 
    private Button serverBtn;
    [SerializeField] 
    private Button clientBtn;
    
    // Start is called before the first frame update
    void Start()
    {
        hostBtn.onClick.AddListener(() =>
        {
            NetworkManager.Singleton.StartHost();
        });
        serverBtn.onClick.AddListener(() =>
        {
            NetworkManager.Singleton.StartServer();
        });
        clientBtn.onClick.AddListener(() =>
        {
            NetworkManager.Singleton.StartClient();
        });
    }
}
