Touch Screen Movement Unity2d

Target Platforms Mobile

I am trying to figure out how to implement touchscreen for android. I want to be able to tap the left hand of the screen to go left while achieving the same type of movement I currently have and tap the right side of the screen to go right with the same type of movement I currently have.

The code I am using for player movement is:

using UnityEngine;
using System.Collections;

public class movement : MonoBehaviour
{

    public Vector2 leftForce = new Vector2(-5, 5);
    public Vector2 rightForce = new Vector2(5, 5);


    // Update is called once per frame
    void Update()
    {
        // Jump Left
        if (Input.GetKeyDown("a"))
        {
            GetComponent<Rigidbody2D>().AddForce(leftForce, ForceMode2D.Impulse);
        }

        //Jump Right

        if (Input.GetKeyDown("d"))
        {
            GetComponent<Rigidbody2D>().AddForce(rightForce, ForceMode2D.Impulse);
        }

The code I have for movement is very simple, but I haven’t been able to find the right tutorial that explains how to add touch functionality that uses this same type of code.

Thank you all for your time!

Well, you can get the touch position, and just determine what side of the screen it’s on. Find the middle of the screen by width/2, and then x > mid and x < mid.
