How to make a touch on unity?

Question

Unity

using UnityEngine;
using System.Collections;

public class chel : MonoBehaviour
{
public Rigidbody2D rb;
public float jumpForce;
public float speed;

private void Update()
{
if (Input.GetKey(KeyCode.A))
{
transform.Translate(Vector2.left * speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.D))
{
transform.Translate(Vector2.right * speed * Time.deltaTime);
}
}
private void OnCollisionEnter2D(Collision2D collision)
{
rb.velocity = new Vector2(0, 0);
rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
}

}
I was trying to make a game like doodle jump for android, but in the movement I put the buttons a (left) and d (right). How to make it possible to move by tapping on the smartphone screen?

Track a panel click using the IPointerEnterHandler , IPointerExitHandler interfaces attached to the object's script. The parameter of the methods implemented by these interfaces will be PointerEventData , using its property eventData.pressPosition.x, you can understand where the click was made.
Accordingly, it remains to calculate whether there was a click on the left or right side of the screen. It's very easy to do this:

bool isRightClick = eventData.pressPosition.x > Screen.width / 2;
bool isLeftClick = eventData.pressPosition.x < Screen.width / 2;

Screen.width, of course, should be cached.
Accordingly, if you click on the left side of the screen, we process the movement to the left, and vice versa.
