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 

[SerializeField] 
private float thrusterForce = 20f;
[SerializeField] 
private ConfigurableJoint joint

 在其Start方法中添加以下语句

joint = GetComponent<ConfigurableJoint>();

在其Update方法中添加以下语句 

Vector3 force = Vector3.zero;
if (Input.GetButton("Jump"))
{force = Vector3.up * thrusterForce;joint.yDrive = new JointDrive{positionSpring = 0f,positionDamper = 0f,maximumForce = 0f,};
}
else
{joint.yDrive = new JointDrive{positionSpring = 20f,positionDamper = 0f,maximumForce = 40f,};}
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

public void Thrust(Vector3 _thrusterForce)
{thrusterForce = _thrusterForce;
}

 在其PerformMovement方法中添加以下语句

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

2.限制玩家视角

 修改PlayerController.cs

添加以下属性

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

对其PerformRotation方法进行一下修改

private void PerformRotation()
{if (yRotation != Vector3.zero){rb.transform.Rotate(yRotation);}if (xRotation != Vector3.zero){cam.transform.Rotate(xRotation);cameraRoatationTotal += xRotation.x;cameraRoatationTotal = Mathf.Clamp(cameraRoatationTotal, -cameraRotationLimit, +cameraRotationLimit);cam.transform.localEulerAngles = new Vector3(cameraRoatationTotal, 0f, 0f);}
}

3.射击的实现

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

using System;[Serializable]
public class PlayerWeapon
{public string name = "M16";public int damage = 10;public float range = 100f;
}

（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

using System;
using UnityEngine;public class GameManager : MonoBehaviour
{private static string info;public static void UpdateInfo(String _info){info = _info;}private void OnGUI(){GUILayout.BeginArea(new Rect(200f,200f,200f,400f));GUILayout.BeginVertical();GUILayout.Label(info);GUILayout.EndVertical();GUILayout.EndArea();}
}

（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

using Unity.Netcode;
using UnityEngine;public class PlayerShooting : NetworkBehaviour
{[SerializeField]private PlayerWeapon weapon;[SerializeField] private LayerMask mask;private Camera cam;// Start is called before the first frame updatevoid Start(){cam = GetComponentInChildren<Camera>();}// Update is called once per framevoid Update(){if(Input.GetButton("Fire1")){Shoot();}}private void Shoot(){RaycastHit hit;if (Physics.Raycast(cam.transform.position, cam.transform.forward, out hit,weapon.range,mask)){ShootServerRpc(hit.collider.name,weapon.damage);}}[ServerRpc]private void ShootServerRpc(string hittedName,int damage){GameManager.UpdateInfo(transform.name+" hit "+hittedName);}
}

（4） 修改NetworkUI.cs，实现“点击按钮后按钮消失”

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 updatevoid Start(){hostBtn.onClick.AddListener(() =>{NetworkManager.Singleton.StartHost();DestroyAllButtons();});serverBtn.onClick.AddListener(() =>{NetworkManager.Singleton.StartServer();DestroyAllButtons();});clientBtn.onClick.AddListener(() =>{NetworkManager.Singleton.StartClient();DestroyAllButtons();});}private void DestroyAllButtons(){Destroy(hostBtn.gameObject);Destroy(serverBtn.gameObject);Destroy(clientBtn.gameObject);}
}

4.附录 

（1）测试效果图

（按住空格起飞，朝向任意碰撞体按下鼠标左键，屏幕左上方出现命中提示） 

（2）部分工程文件完整代码

• PlayerInput.cs

using UnityEngine;public class PlayerInput : MonoBehaviour
{[SerializeField]private float speed = 5f;[SerializeField] private float thrusterForce = 20f;[SerializeField] private PlayerController playerControllor;[SerializeField] private float lookSensitivity = 8f;[SerializeField] private ConfigurableJoint joint;// Start is called before the first frame updatevoid Start(){Cursor.lockState = CursorLockMode.Locked;joint = GetComponent<ConfigurableJoint>();}// Update is called once per framevoid Update(){float xMov = Input.GetAxisRaw("Horizontal");float yMov = Input.GetAxisRaw("Vertical");Vector3 velocity = (transform.right * xMov + transform.forward * yMov).normalized*speed;playerControllor.Move(velocity);float xMouse = Input.GetAxisRaw("Mouse X");float yMouse = Input.GetAxisRaw("Mouse Y");Vector3 yRotation = new Vector3(0f, xMouse, 0f)*lookSensitivity;Vector3 xRotation = new Vector3(-yMouse, 0f, 0f)*lookSensitivity;playerControllor.Rotate(yRotation,xRotation);Vector3 force = Vector3.zero;if (Input.GetButton("Jump")){force = Vector3.up * thrusterForce;joint.yDrive = new JointDrive{positionSpring = 0f,positionDamper = 0f,maximumForce = 0f,};}else{joint.yDrive = new JointDrive{positionSpring = 20f,positionDamper = 0f,maximumForce = 40f,};}playerControllor.Thrust(force);}
}

• PlayerController.cs 

using UnityEngine;public class PlayerController : MonoBehaviour
{[SerializeField] private Rigidbody rb;[SerializeField] private Camera cam;private Vector3 velocity = Vector3.zero;//速度：每秒钟移动的距离private Vector3 yRotation=Vector3.zero;//旋转角色private Vector3 xRotation = Vector3.zero;//旋转视角private float cameraRoatationTotal = 0f;//累计转了多少度[SerializeField]private float cameraRotationLimit = 85f;private Vector3 thrusterForce = Vector3.zero;//向上的推力public void Move(Vector3 _velocity){velocity = _velocity;}public void Rotate(Vector3 _yRotation, Vector3 _xRotation){yRotation = _yRotation;xRotation = _xRotation;}public void Thrust(Vector3 _thrusterForce){thrusterForce = _thrusterForce;}private void PerformMovement(){if (velocity != Vector3.zero){rb.MovePosition(rb.position+velocity*Time.fixedDeltaTime);}if (thrusterForce != Vector3.zero){rb.AddForce(thrusterForce);//作用Time.fixedDeltaTime秒：0.02秒thrusterForce = Vector3.zero;}}private void PerformRotation(){if (yRotation != Vector3.zero){rb.transform.Rotate(yRotation);}if (xRotation != Vector3.zero){cam.transform.Rotate(xRotation);cameraRoatationTotal += xRotation.x;cameraRoatationTotal = Mathf.Clamp(cameraRoatationTotal, -cameraRotationLimit, +cameraRotationLimit);cam.transform.localEulerAngles = new Vector3(cameraRoatationTotal, 0f, 0f);}}private void FixedUpdate(){PerformMovement();PerformRotation();}
}
