i want to make the ball jump along y axis while moving on x axis at any point? what do i have to do?

using UnityEngine;
using System.Collections;

public class Lcircle : MonoBehaviour {

public float Ballspeed = 1F;
public Vector3 playerPos;

void Update () {
	
       float xPos = gameObject.transform.position.x + (Input.GetAxis ("Horizontal") * Ballspeed);
       playerPos = new Vector3 (Mathf.Clamp(xPos, -7, -1), -3, 0);
   gameObject.transform.position = playerPos;
       }

}

You could use the Vector3.Lerp() function to lerp between the ground y-value and the y-value of the highest point in your jump and then the other way around. But that won’t give the most realistic effect. You could also use unity physics and put a velocity on your ball’s y-axis.

Or, like I just did in the game I am currently writing, you can use a coroutine function for jumping

private float m_JumpSpeed = 10f;

private IEnumerator Jump()
    {

        float gravity = -Physics.gravity.y;
        float jumpVelocity = m_JumpSpeed;
        float initialY = transform.position.y;

        while (transform.position.y >= initialY)
        {
            transform.Translate(0f, jumpVelocity * Time.deltaTime, 0f);
            jumpVelocity -= gravity;
            yield return null;
        }


        transform.position = new Vector3(transform.position.x, initialY, transform.position.z);
    }
