    2.限制玩家视角

    3.射击的实现

    4.附录

    1.飞行的实现

    （1）在Player预制体上挂载Configuration Joint组件，并修改其Y Drive属性

    （2） 修改PlayerInput.cs和PlayerController.cs以实现飞行

    • PlayerInput.cs

    添加以下属性 

    1. [SerializeField] 
    2. private float thrusterForce = 20f;
    3. [SerializeField] 
    4. private ConfigurableJoint joint

     在其Start方法中添加以下语句

    joint = GetComponent();

    在其Update方法中添加以下语句 

    1. Vector3 force = Vector3.zero;
    2. if (Input.GetButton("Jump"))
    3. {
    4.     force = Vector3.up * thrusterForce;
    5.     joint.yDrive = new JointDrive
    6.     {
    7.         positionSpring = 0f,
    8.         positionDamper = 0f,
    9.         maximumForce = 0f,
    10.     };
    11. }
    12. else
    13. {
    14.     joint.yDrive = new JointDrive
    15.     {
    16.         positionSpring = 20f,
    17.         positionDamper = 0f,
    18.         maximumForce = 40f,
    19.         };
    20.     }
    21. playerControllor.Thrust(force);
    • PlayerController.cs

    添加以下属性 

    private Vector3 thrusterForce = Vector3.zero;//向上的推力

     添加以下方法

    1. public void Thrust(Vector3 _thrusterForce)
    2. {
    3.     thrusterForce = _thrusterForce;
    4. }

     在其PerformMovement方法中添加以下语句

    1. if (thrusterForce != Vector3.zero)
    2. {
    3.     rb.AddForce(thrusterForce);//作用Time.fixedDeltaTime秒：0.02秒
    4.     thrusterForce = Vector3.zero;
    5. }

    2.限制玩家视角

     修改PlayerController.cs

    添加以下属性

    1. private float cameraRoatationTotal = 0f;//累计转了多少度
    2. [SerializeField]
    3. private float cameraRotationLimit = 85f;

    对其PerformRotation方法进行一下修改

    1. private void PerformRotation()
    2. {
    3.     if (yRotation != Vector3.zero)
    4.     {
    5.         rb.transform.Rotate(yRotation);
    6.     }
    7.     if (xRotation != Vector3.zero)
    8.     {
    9.         cam.transform.Rotate(xRotation);
    10.         cameraRoatationTotal += xRotation.x;
    11.         cameraRoatationTotal = Mathf.Clamp(cameraRoatationTotal, -cameraRotationLimit, +cameraRotationLimit);
    12.         cam.transform.localEulerAngles = new Vector3(cameraRoatationTotal, 0f, 0f);
    13.     }
    14. }

    3.射击的实现

    （1） 创建并编写PlayerWeapon.cs，将其移动至Assets/Scripts/Player

    1. using System;
    2.  
    3. [Serializable]
    4. public class PlayerWeapon
    5. {
    6.     public string name = "M16";
    7.     public int damage = 10;
    8.     public float range = 100f;
    9. }

    （2）在场景中创建空物体“GameManager”，创建并编写GameManager.cs并挂载至空物体“GameManager”

    • GameManager.cs
    1. using System;
    2. using UnityEngine;
    3.  
    4. public class GameManager : MonoBehaviour
    5. {
    6.     private static string info;
    7.  
    8.     public static void UpdateInfo(String _info)
    9.     {
    10.         info = _info;
    11.     }
    12.  
    13.     private void OnGUI()
    14.     {
    15.         GUILayout.BeginArea(new Rect(200f,200f,200f,400f));
    16.         GUILayout.BeginVertical();
    17.         GUILayout.Label(info);
    18.         GUILayout.EndVertical();
    19.         GUILayout.EndArea();
    20.     }
    21. }

    （3）创建并编写PlayerShooting.cs并将其挂载至Player预制体，将其移至Assets/Scripts/Player

    1. using Unity.Netcode;
    2. using UnityEngine;
    3.  
    4. public class PlayerShooting : NetworkBehaviour
    5. {
    6.     [SerializeField]
    7.     private PlayerWeapon weapon;
    8.     [SerializeField] 
    9.     private LayerMask mask;
    10.  
    11.     private Camera cam;
    12.     
    13.     // Start is called before the first frame update
    14.     void Start()
    15.     {
    16.         cam = GetComponentInChildren();
    17.     }
    18.  
    19.     // Update is called once per frame
    20.     void Update()
    21.     {
    22.         if(Input.GetButton("Fire1"))
    23.         {
    24.             Shoot();
    25.         }
    26.     }
    27.  
    28.     private void Shoot()
    29.     {
    30.         RaycastHit hit;
    31.         if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit,weapon.range,mask))
    32.         {
    33.             ShootServerRpc(hit.collider.name,weapon.damage);
    34.         }
    35.     }
    36.  
    37.     [ServerRpc]
    38.     private void ShootServerRpc(string hittedName,int damage)
    39.     {
    40.         GameManager.UpdateInfo(transform.name+" hit "+hittedName);
    41.     }
    42. }

    （4） 修改NetworkUI.cs，实现“点击按钮后按钮消失”

    1. using Unity.Netcode;
    2. using UnityEngine;
    3. using UnityEngine.UI;
    4.  
    5. public class NetworkManagerUI : MonoBehaviour
    6. {
    7.     [SerializeField] 
    8.     private Button hostBtn;
    9.     [SerializeField] 
    10.     private Button serverBtn;
    11.     [SerializeField] 
    12.     private Button clientBtn;
    13.     
    14.     // Start is called before the first frame update
    15.     void Start()
    16.     {
    17.         hostBtn.onClick.AddListener(() =>
    18.         {
    19.             NetworkManager.Singleton.StartHost();
    20.             DestroyAllButtons();
    21.         });
    22.         serverBtn.onClick.AddListener(() =>
    23.         {
    24.             NetworkManager.Singleton.StartServer();
    25.             DestroyAllButtons();
    26.         });
    27.         clientBtn.onClick.AddListener(() =>
    28.         {
    29.             NetworkManager.Singleton.StartClient();
    30.             DestroyAllButtons();
    31.         });
    32.     }
    33.  
    34.     private void DestroyAllButtons()
    35.     {
    36.         Destroy(hostBtn.gameObject);
    37.         Destroy(serverBtn.gameObject);
    38.         Destroy(clientBtn.gameObject);
    39.     }
    40. }
