移动代码

 　　 //移动代码
 　　 public CharacterController controller;//角色控制器
     public float speed = 12f;//移动速度
     public float gravity = -20f;//重力加速度
     public float jumpHeight = 3f;//跳跃高度

     public Transform groundCheck;//碰撞检测物体(空物体),模型底部的东西 , 用于检测是否落地
     public float groundDistance = 0.4f;//半径大小
     public LayerMask groundMask;//被检测的被碰撞物体

     Vector3 velocity;//移动速度
     bool isGrounded;//脚底是否与地面接触

     private Animator animator;
     private void Start()
     {
         animator = this.GetComponentInChildren<Animator>();

     }

     float t;
     // Update is called once per frame
     void Update()
     {
         isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

         if (isGrounded && velocity.y < )
         {
             velocity.y = -2f;
         }

         if (Input.GetButtonDown("Jump") && isGrounded)
         {

             velocity.y = Mathf.Sqrt(jumpHeight * -2f * gravity);

         }

         float x = Input.GetAxis("Horizontal");
         float z = Input.GetAxis("Vertical");

         Vector3 move = transform.right * x + transform.forward * z;

         controller.Move(move * speed * Time.deltaTime);

         velocity.y += gravity * Time.deltaTime;

         controller.Move(velocity * Time.deltaTime);
     }

视角代码

 　　 //视角代码
 　　 public float 鼠标灵敏度 = 100f;
     public Transform 玩家;
     float xRoation = 0f;
     // Start is called before the first frame update
     void Start()
     {
         Cursor.lockState = CursorLockMode.Locked;
     }

     // Update is called once per frame
     void Update()
     {
         float mouseX = Input.GetAxis("Mouse X") * 鼠标灵敏度 * Time.deltaTime;
         float mouseY = Input.GetAxis("Mouse Y") * 鼠标灵敏度 * Time.deltaTime;

         xRoation -= mouseY;
         xRoation = Mathf.Clamp(xRoation, -75f, 75f);

         transform.localRotation = Quaternion.Euler(xRoation, 0f, 0f);
         玩家.Rotate(Vector3.up * mouseX);
     }
