(help) Please Can Someone Help Me With This Script, I Have Just Started Using Unity.

Unity Engine

Hello all,
I am a complete begginier to Unity and c#. However I have recently been trying to create a 2D game by following tutorials and I have run into an issue with some script in C# and was hoping that someonw could help. My aim is to make it so that the player can move both left and right on a surface and they will shoot in the corresponding direction rather than currently always right. I have had a gok and this, trying to use a few different ideas but just cant crack it. In addition, I was also hoping to add the ability too shoot upwards when a certain key is pressed on the keyboard. Many thanks, Josh. Here is the Script:
Bullet:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class bullet : MonoBehaviour
{

public float speed = 20f;
public int damage = 40;
public Rigidbody2D rb;
public GameObject impactEffect;

// Use this for initialization
void Start()
{
rb.velocity = transform.right * speed;
}

void OnTriggerEnter2D(Collider2D hitInfo)
{
Health enemy = hitInfo.GetComponent();
if (enemy != null)
{
enemy.TakeDamage(damage);
if (damage == 100)
{
Destroy(gameObject);
}
}

Instantiate(impactEffect, transform.position, transform.rotation);

//Destroy(gameObject);
}

}
Weapon:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Weapon : MonoBehaviour
{
public Transform firePoint;
public GameObject bulletPrefab;

// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
if (Input.GetButtonDown(“Fire1”))
{
Shoot();
}
}

void Shoot()
{
//shooting logic
Instantiate(bulletPrefab, firePoint.position, firePoint.rotation);
}
}
Player Controller:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour
{
public float speed;
Rigidbody2D rb;

// Start is called before the first frame update
void Start()
{
rb = GetComponent();
}

// Update is called once per frame
void Update()
{

}

void FixedUpdate()
{
float move = Input.GetAxis(“Horizontal”);
rb.velocity = new Vector2(speed * move, rb.velocity.y);
}
}

are you sure the firepoint is in the right direction?

Next time post your code with code tags so it is easier to read.

So on your bullet it is always going right because of this line: rb.velocity = transform.right * speed;

Maybe try transform.forward instead of right. Or, for a different approach: Find the X scale of the player (either 1 or -1) and have the bullet check which direction the player is in first.

void Start()
{
if(player.transform.scale > 0)
{
rb.velocity = transform.right * speed;
}
else
{
rb.velocity = transform.right * -speed;
}
}

Not the greatest way but its what i can think of away from the top of my head.

but wait doesnt transform. right go forward so if its pointing in the right direction shouldnt it work
