Hi,

I am making a remake of the game Pong Click Here

This is the Ball Script

using System;
using System.IO;
using UnityEngine;
using UnityEngine.SceneManagement;

public class Ball : MonoBehaviour
{
    public float speed = 12;
    void Start()
    {
        // Initial Velocity
        GetComponent<Rigidbody2D>().velocity = Vector2.right * speed;
    }
    float hitFactor(Vector2 ballPos, Vector2 racketPos,
                    float racketHeight)
    {
        // ascii art:
        // ||  1 <- at the top of the racket
        // ||
        // ||  0 <- at the middle of the racket
        // ||
        // || -1 <- at the bottom of the racket
        return (ballPos.y - racketPos.y) / racketHeight;
    }

    void OnCollisionEnter2D(Collision2D col)
    {
        // Note: 'col' holds the collision information. If the
        // Ball collided with a racket, then:
        //   col.gameObject is the racket
        //   col.transform.position is the racket's position
        //   col.collider is the racket's collider

        // Hit the left Racket?
        if (col.gameObject.name == "RacketLeft")
        {
            // Calculate hit Factor
            float y = hitFactor(transform.position,
                                col.transform.position,
                                col.collider.bounds.size.y);

            // Calculate direction, make length=1 via .normalized
            Vector2 dir = new Vector2(1, y).normalized;

            // Set Velocity with dir * speed
            GetComponent<Rigidbody2D>().velocity = dir * speed;
        }

        // Hit the right Racket?
        if (col.gameObject.name == "RacketRight")
        {
            // Calculate hit Factor
            float y = hitFactor(transform.position,
                                col.transform.position,
                                col.collider.bounds.size.y);

            // Calculate direction, make length=1 via .normalized
            Vector2 dir = new Vector2(-1, y).normalized;

            // Set Velocity with dir * speed
            GetComponent<Rigidbody2D>().velocity = dir * speed;
        }
        if (col.gameObject.name == "WallLeft")
        {
            SceneManager.LoadScene("RightSide Scene");
        }
        if (col.gameObject.name == "WallRight")
        {
            SceneManager.LoadScene("LeftSide Scene");
        }
    }
}

This is the Rackets Script

using UnityEngine;

public class MoveRacket : MonoBehaviour
{
    public float speed = 30;
    public string axis = "Vertical";

    void FixedUpdate()
    {
        float v = Input.GetAxisRaw(axis);
        GetComponent<Rigidbody2D>().velocity = new Vector2(0, v) * speed;
    }
}

Let me know if you need anything else! I just need to know how to add Touch Controls for Android

Interesting! I might look later, if I remember
