Brackey's 2D Shooting in Unity (Tutorial) Problem

Getting Started
1

Hi,

I was looking for a way to use raycasts for my platformer player to shoot. I used the tutorial from Brackey’s

It’s the second half in case you’re unfamiliar :wink:

You can also download the project, which works totally fine as I can see, no errors etc.

https://github.com/Brackeys/2D-Shooting

However when I used the main script for shooting the raycast (RayCastWeapon.cs), I get an error.

Here’s the srcript:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RayCastWeapon : MonoBehaviour {

    public Transform firePoint;
    public int damage = 40;
    public GameObject impactEffect;
    public LineRenderer lineRenderer;
   
    // Update is called once per frame
    void Update () {
        if (Input.GetButtonDown("Fire1"))
        {
            StartCoroutine(Shoot());
        }
    }

    IEnumerator Shoot ()
    {
        RaycastHit2D hitInfo = Physics2D.Raycast(firePoint.position, firePoint.right);

        if (hitInfo)
        {
            Enemy enemy = hitInfo.transform.GetComponent<Enemy>();
            if (enemy != null)
            {
                enemy.TakeDamage(damage);
            }

            Instantiate(impactEffect, hitInfo.point, Quaternion.identity);

            lineRenderer.SetPosition(0, firePoint.position);
            lineRenderer.SetPosition(1, hitInfo.point);
        } else
        {
            lineRenderer.SetPosition(0, firePoint.position);
            lineRenderer.SetPosition(1, firePoint.position + firePoint.right * 100);
        }

        lineRenderer.enabled = true;

        yield return 0;

        lineRenderer.enabled = false;
    }
}

The issue I seem to be having is with the line:

Enemy enemy = hitInfo.transform.GetComponent<Enemy>();

“Enemy” isn’t defined anywhere.

I’m using Unity 2020.3.9f1. I loaded the Brackey’s project into the same version which works.

What am I missing?

Jay.

Did you create an Enemy class?

I’ve just wroked it out, it’s looking for an “Enemy” script/class. I had no idea, but sorted now thanks.
