Line renderer not working

Questions & Answers
1

So I was trying to make a very simple bullet which literally just casts a line from the tip of the gun forward the same amount as a raycast. I’m thinking my issue may have something to do with the fact that the accessed line renderer isn’t on the same object as the script but I did try this before and it seemed to work. I would put the line renderer on the same object but it’s already in use by another script on the object. I’ll put the code I think is relevant here:

RaycastHit hit;
Ray isGrounded = new ray (transform.position, cam.forward);
if (Physics.RayCast (isGrounded, out hit, reach)){
line.SetPosition(1, pistol.transform.position);
line.SetPosition(2, hit.point);
}}

I understand the line should only be drawn when there is a raycast hit, but I have also set up the print function so I know when it should be called. I’m really lost with this ass it worked fine with practically identical code on the other script so I figure it must be something to do with the line renderer not actually being attached to the player’s object. Please help.

Hey @Deathleaper! Try this code and when the shoot function, call the line renderer.
I modified this code from Brackyes, just so you know.

`using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using JetBrains.Annotations;

public class OSGun : MonoBehaviour
{
public float damage = 10f;
public float range = 100f;

public int maxAmmo = 10;
private int currentAmmo;
public float reloadTime = 1f;
private bool isReloading = false;

public Camera fpsCam;
public ParticleSystem muzzleFlash;

public Transform shotText;

public Animator animator;

public AudioSource audioData;

void Start()
{
   currentAmmo = maxAmmo;
   audioData = GetComponent<AudioSource>();
}

void OnEnable()
{
    isReloading = false;
    animator.SetBool("Reloading", false);
    animator.SetBool("Shooting", false);
    shotText.GetComponent<Text>().text = currentAmmo + "/" + maxAmmo.ToString(); 
}
void Update()
{
    if (isReloading)
    {
        return;
    }
    if (currentAmmo <= 0)
    {
        StartCoroutine(Reload());
        return;
    }
    if (Input.GetButtonDown("Fire1"))
    {
        animator.SetBool("Shooting", true);
        Shoot();
        shotText.GetComponent<Text>().text = currentAmmo + "/" + maxAmmo.ToString();
    }
    if (Input.GetButtonUp("Fire1"))
    {
        animator.SetBool("Shooting", false);
    }

    if (Input.GetKey("r"))
    {
        if (currentAmmo == maxAmmo)
        {
            return;
        }
        else
        {
            StartCoroutine(Reload());
            return;
        }
    }
}

IEnumerator Reload ()
{
    isReloading = true;
    Debug.Log("Reload...");

    animator.SetBool("Reloading", true);

    yield return new WaitForSeconds(reloadTime - .25f);
    animator.SetBool("Reloading", false);
    yield return new WaitForSeconds(.25f);

    currentAmmo = maxAmmo;
    shotText.GetComponent<Text>().text = maxAmmo + "/" + maxAmmo.ToString();
    isReloading = false;
}
void Shoot()
{

    muzzleFlash.Play();

    currentAmmo--;

    audioData.Play(0);

    RaycastHit hit;
    if (Physics.Raycast(fpsCam.transform.position, fpsCam.transform.forward, out hit, range))
    {
        Debug.Log(hit.transform.name);
        
        Target target = hit.transform.GetComponent<Target>();
        if (target != null)
        {
            target.TakeDamage(damage);
        }
    }  else if (Physics.Raycast(fpsCam.transform.position, fpsCam.transform.forward, out hit, range))
    {
        Debug.Log(hit.transform.name);

        GlassTarget target = hit.transform.GetComponent<GlassTarget>();
        if (target != null)
        {
            target.TakeDamage(damage);
        }
    }
}

public void SetAmmoOnEquip()
{
    shotText.GetComponent<Text>().text = currentAmmo + "/" + maxAmmo.ToString();
}
public void SetAmmoOnUnequip()
{
    shotText.GetComponent<Text>().text = "--";
}

}
