              how can I add Sprint into my Script ?,How can I add Sprint function ??
I want to add Sprint function in my script ,but I don't have any idea how to do it..

         public float jumpheight = 2f;

         public float grounddist = 0.2f;
         public float dashdist = 5f;
 
         
         public LayerMask ground;
         public Rigidbody rigidbody;
         public Vector3 input = Vector3.zero;
         public bool isGrounded = true;
         private Transform groundCheck;
 
         private void Start()
         {
             rigidbody = this.GetComponent<Rigidbody>();
             groundCheck = transform.GetChild(0);
             Cursor.lockState = CursorLockMode.Locked;
         }
         // Update is called once per frame
         void Update()
         {
             isGrounded = Physics.CheckSphere(groundCheck.position, grounddist, ground, QueryTriggerInteraction.Ignore);
            
             if (Input.GetButtonDown("Jump") && isGrounded)
                 rigidbody.AddForce(Vector3.up * Mathf.Sqrt(jumpheight * -2f * Physics.gravity.y), ForceMode.VelocityChange);
 
             
             if (Input.GetKeyDown(KeyCode.R)) //Dash
             {
                 Vector3 dashVel = Vector3.Scale(transform.forward, dashdist * new Vector3((Mathf.Log(1f / (Time.deltaTime * rigidbody.drag + 1))
                     / -Time.deltaTime), 0, (Mathf.Log(1f / (Time.deltaTime * rigidbody.drag + 1)) / -Time.deltaTime)));
                 rigidbody.AddForce(dashVel, ForceMode.VelocityChange);
             }
 
             float translation = Input.GetAxis("Vertical") * speed;
             float straffe = Input.GetAxis("Horizontal") * speed;
             translation *= Time.deltaTime;
             straffe *= Time.deltaTime;
 
             transform.Translate(straffe, 0, translation);
             if (Input.GetKeyDown("escape"))
                 Cursor.lockState = CursorLockMode.None;
            
         }
     }
 }
