Feedback How To Combine These 2 Scripts Into 1 (If possible)

Hi
I'm making a third person practice game. I'm trying to make a effective Character Controller movement with some smooth Animation. (That i have downloaded from Mixamo)
I have made 2 Scripts for my project; first script is for the character controller and movement, the second is for the animation.

Code (CSharp):

1. public class PlayerMovement : MonoBehaviour
2. {
3.     private float InputX, InputZ, _speed;
4.     private Camera _cam;
5.     private CharacterController _controller;
6.     private float gravity;
7.  
8.     private Vector3 desiredMoveDirection;
9.     [SerializeField]
10.     float _rotationSpeed = 0.3f;
11.     [SerializeField]
12.     float allowRotation = 0.1f;
13.     [SerializeField]
14.     float _movementSpeed = 1f;
15.     [SerializeField]
16.     float gravitymultiplier = 0.5f;
17.  
18.  
19.     void Start()
20.     {
21.  
22.         _controller = GetComponent<CharacterController>();
23.         _cam = Camera.main;
24.  
25.  
26.     }
27.  
28.     // Update is called once per frame
29.     void Update()
30.     {
31.         InputX = Input.GetAxis("Horizontal");
32.         InputZ = Input.GetAxis("Vertical");
33.  
34.         InputDecider();
35.         MovementManager();
36.  
37.     }
38.  
39.  
40.  
41.     void InputDecider()
42.     {
43.         _speed = new Vector2(InputX, InputZ).sqrMagnitude;
44.  
45.         if(_speed > allowRotation)
46.         {
47.             RotationManager();
48.         }
49.         else
50.         {
51.             desiredMoveDirection = Vector3.zero;
52.         }
53.     }
54.  
55.  
56.     void RotationManager()
57.     {
58.         var forward = _cam.transform.forward;
59.         var right = _cam.transform.right;
60.  
61.         forward.y = 0f;
62.         right.y = 0f;
63.  
64.         forward.Normalize();
65.         right.Normalize();
66.  
67.         desiredMoveDirection = forward * InputZ + right * InputX;
68.  
69.         transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(desiredMoveDirection), _rotationSpeed);
70.     }
71.  
72.     void MovementManager()
73.     {
74.         gravity -= 9.81f * Time.deltaTime;
75.         gravity = gravity * gravitymultiplier;
76.  
77.         Vector3 moveDirection = desiredMoveDirection * (_movementSpeed * Time.deltaTime);
78.         moveDirection = new Vector3(moveDirection.x, gravity, moveDirection.z);
79.         _controller.Move(moveDirection);
80.  
81.         if(_controller.isGrounded)
82.         {
83.             gravity = 0f;
84.         }
85.     }
86. }

Animation Script:

Code (CSharp):

1. public class WalkingAnimation : MonoBehaviour
2. {
3.  
4.     [SerializeField]
5.     private Animator _animator;
6.     [SerializeField]
7.     private float inputX;
8.     float inputZ;
9.  
10.  
11.     void Start()
12.     {
13.         _animator = this.gameObject.GetComponent<Animator>();
14.  
15.  
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.  
22.         inputX = Input.GetAxis("Horizontal");
23.         _animator.SetFloat("InputX", inputX);
24.  
25.         inputZ = Input.GetAxis("Vertical");
26.         _animator.SetFloat("InputZ", inputZ);
27.     }
28. }

I'm really bad at scripting, so I dont know how to combine these 2 Scripts into 1.
