How to create gun sprinting animation by script.

Hi, I extracted all this from the standard third person controller unity provides, the animationSpeedMultiplier variable will alter how fast your animations cycle.s play.

 using UnityEngine;
 
 using UnityEngine.AI;
 
 public class Character : MonoBehaviour
 
 {
 
     [Header("Animator")]
     [SerializeField]
     RuntimeAnimatorController animatorController;
 
     [SerializeField] AnimatorOverrideController animatorOverrideController;
 
     [SerializeField] Avatar characterAvatar;
 
     [SerializeField] [Range(.1f, 1f)] float animatorForwardCap = 1f;
 
 
     [Header("Nav Mesh Agent")]
 
     [SerializeField]
     float navMeshAgentSteeringSpeed = 1.0f;
 
     [SerializeField] float navMeshAgentStoppingDistance = 1.3f;
 
 
     NavMeshAgent navMeshAgent;
 
     Animator animator;
 
     Rigidbody ridigBody;
 
     public AnimatorOverrideController GetOverrideController()
 
     {
         return animatorOverrideController;
     }
 
 
     void Move(Vector3 movement)
     {
 
         SetForwardAndTurn(movement);
 
         ApplyExtraTurnRotation();
 
         UpdateAnimator();
     }
 
 
 
     void SetForwardAndTurn(Vector3 movement)
 
     {
         // convert the world relative moveInput vector into a local-relative
 
         // turn amount and forward amount required to head in the desired direction
 
         if (movement.magnitude > moveThreshold)
 
         {
             movement.Normalize();
         }
 
 
         var localMove = transform.InverseTransformDirection(movement);
 
         turnAmount = Mathf.Atan2(localMove.x, localMove.z);
 
         forwardAmount = localMove.z;
 
     }
 
 
 
     void UpdateAnimator()
 
     {
         animator.SetFloat("Forward", forwardAmount * animatorForwardCap, 0.1f, Time.deltaTime);
 
         animator.SetFloat("Turn", turnAmount, 0.1f, Time.deltaTime);
 
         animator.speed = animationSpeedMultiplier;
     }
 
 
 
     void ApplyExtraTurnRotation()
     {
 
         // help the character turn faster (this is in addition to root rotation in the animation)
 
         float turnSpeed = Mathf.Lerp(stationaryTurnSpeed, movingTurnSpeed, forwardAmount);
 
         transform.Rotate(0, turnAmount * turnSpeed * Time.deltaTime, 0);
     }
 
 
 
     void OnAnimatorMove()
     {
         // we implement this function to override the default root motion.
         // this allows us to modify the positional speed before it's applied.
         if (Time.deltaTime > 0)
         {
             Vector3 velocity = (animator.deltaPosition * moveSpeedMultiplier) / Time.deltaTime;
 
             // we preserve the existing y part of the current velocity.
             velocity.y = ridigBody.velocity.y;
             ridigBody.velocity = velocity;
         }
     }

But you can import the whole thing by going here ->
