C# script for animation using joystick asset .

I try to create one C# script for animation using joystick asset https://assetstore.unity.com/packages/tools/input-management/joystick-pack-107631
The link I try to follow like video tutorial is this:

My project needs to use into 2D animation (without rotation of player).
The video tutorial comes with a variable named controller the type is CharacterController2D.
I cannot use https://github.com/Brackeys/2D-Character-Controller.
Even if it seems a simple problem it is very difficult to implement. Do you have a good video tutorial for last Unity 2018.2.17f1 ( 64-bit ).
This is the script with variables used like Parameters in Animator and my animations into Base Layer (PlayerIdle, PlayerUp, PlayerLeft... ) :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class MoveByTouch : MonoBehaviour {
6.     public CharacterController2D controller;
7.     public Animator animator;
8.     public Joystick joystick;
9.     public float runSpeed = 40f;
10.     float horizontalMove = 0f;
11.     bool jump = false;
12.     bool crouch = false;
13.  
14.     // Update is called once per frame
15.     void Update () {
16.         //horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;
17.         //horizontalMove = joystick.Horizontal * runSpeed;
18.         if (joystick.Horizontal >= .2f)
19.         {
20.             horizontalMove = runSpeed;
21.         }
22.         else if (joystick.Horizontal <= -.2f)
23.         {
24.             horizontalMove = -runSpeed;
25.         }
26.         else
27.         {
28.             horizontalMove = 0f;
29.         }
30.  
31.         float verticalMove = joystick.Vertical;
32.  
33.         animator.SetFloat("Speed",Mathf.Abs(horizontalMove));
34.  
35.         if (verticalMove >= .5f ) {
36.             jump = true;
37.             animator.SetBool("IsUp", true);
38.         }
39.  
40.         if (verticalMove <= -.5f)
41.         {
42.             crouch = true;
43.         } else {
44.             crouch = false;
45.         }
46.         /* if (Input.touchCount > 0)
47.         {
48.             Touch touch = Input.GetTouch(0);
49.             Vector3 touchPossition = Camera.main.ScreenToWorldPoint(touch.position);
50.             touchPosition.z = 0;
51.             transform.position = touchPosition;
52.  
53.         } */
54.         /* for (int i = 0; i < Input.touchCount; i++)
55.         {
56.             Vector3 touchPosition = Camera.main.ScreenToWorldPoint(Input.touches[i].position);
57.             Debug.DrawLine(Vector3.zero, touchPosition, Color.red);
58.         } */
59.     }
60. }
