How to replace input axis keyboard button with touch button?

Question

Hello everyone! I am trying to make my game work on android phone. I need to switch from my keyboard input to screen touch input. I am using Input.GetAxis() usually, when the input is my keyboard arrows. I want to replace that keyboard button(s) of axis with particular button(s) of my ui elements, so that when I touch my screen, it will be the same as I would push the keyboard button. I want to do that, because axis settings has lots of settings like 'sensitivity' or 'gravity' and etc. and so I would not need to make that input system by myself, only replace the input button. So how can I do that? Thanks.

Simple solution:

You can try using the following code , for replicating the push of a keyboard button or mouse button..

 float xPos = Input.GetAxis("Mouse X");
 
 float yPos = Input.GetAxis("Mouse Y");
  
      if (Input.touchCount > 0)
      {
          xPos = Input.touches[0].deltaPosition.x;
          yPos = Input.touches[0].deltaPosition.y;
      }

Heres info on how mobile input works:

Recommend solution

Although, I would recommend that if you are using the latest Unity UI .

1) Create a button , and add an event trigger component

2) Add two new events ( on the event trigger component) from the options select "Pointerdown" and "PointerUp". These events will be triggered when you push this button on the UI and release it , respectively.

3) Hook corresponding functions like "OnPointerDown" etc that you'd like to call, into these triggers

4) Use something like the following script to make it work

 void Update () {
 
         if (_isMove == true && (transform.position.x) <= 4.5f) {
                     transform.Translate (Vector3.left * 0.01f);
                             transform.Translate (Vector3.left * 0.01f);
                 }
     }
 
      public void OnPointerDown()
     {
         _isMove = true;
 
                 
     }
     public void OnPointerUp()
     {
         _isMove = false;
     }

using System; using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement;

  public class ButtonHandler : MonoBehaviour
  {
         bool _isMove; //You forgot to add a bool:)
 
 
      void Update()
      {
 
          if (_isMove == true && (transform.position.x) <= 4.5f)
          {
              transform.Translate(Vector3.left * 0.01f);
              transform.Translate(Vector3.left * 0.01f);
          }
      }
 
      public void OnPointerDown()
      {
          _isMove = true;
 
 
      }
      public void OnPointerUp()
      {
          _isMove = false;
