So, I need to use LShift to run, but I can’t exactly figure out how to do so….

I don’t know what to use….

Here my code:

using UnityEngine; using System.Collections;  // This script moves the character controller forward // and sideways based on the arrow keys. // It also jumps when pressing space. // Make sure to attach a character controller to the same game object. // It is recommended that you make only one call to Move or SimpleMove per frame.  public class Move : MonoBehaviour {     CharacterController characterController;      public float speed = 6.0f;     public float jumpSpeed = 8.0f;     public float gravity = 20.0f;     public Transform charBody;     private Vector3 moveDirection = Vector3.zero;     public float mouseSense = 11f;     public float runSpeed = 12f;     public bool isRunning = false;      void Start()     {         characterController = GetComponent<CharacterController>();     }      void Update()     {         if (characterController.isGrounded)         {             // We are grounded, so recalculate             // move direction directly from axes              moveDirection = transform.forward * Input.GetAxis("Horizontal") + transform.right * Input.GetAxis("Vertical");             moveDirection *= speed;             moveDirection = transform.right * Input.GetAxis("Horizontal") + transform.right * Input.GetAxis("Vertical");             moveDirection *= speed;                  if (Input.GetButton("Jump"))             {                 moveDirection.y = jumpSpeed;             }         }                               // Apply gravity. Gravity is multiplied by deltaTime twice (once here, and once below         // when the moveDirection is multiplied by deltaTime). This is because gravity should be applied         // as an acceleration (ms^-2)         moveDirection.y -= gravity * Time.deltaTime;          // Move the controller         characterController.Move(moveDirection * Time.deltaTime);          float MOUSEY = Input.GetAxis("Mouse Y") * mouseSense * Time.deltaTime;         float MOUSEX = Input.GetAxis("Mouse X") * mouseSense * Time.deltaTime;          charBody.Rotate(Vector3.up * MOUSEX);                 } } 

So, when left shift is clicked I want the speed to change to runSpeed…

Can I please have some help doing so?

Thanks
