LineRenderer.SetPosition index out of bounds! Help!
when I run this code it gives me the error:
LineRenderer.SetPosition index out of bounds! UnityEngine.LineRenderer:SetPosition(Int32, Vector3) raycast:Update() (at Assets/Keep/Pack/raycast.cs:66)
here is the code:
using UnityEngine; using System.Collections;
public class raycast : MonoBehaviour {
public int gunDamage = 1;
public float fireRate = 0.25f;
public float weaponRange = 50f;
public float hitForce = 100f;
public Transform gunEnd;
public Camera fpsCam;
private WaitForSeconds shotDuration = new WaitForSeconds(0.07f);
private AudioSource gunAudio;
private LineRenderer laserLine;
private float nextFire;
void Start ()
{
laserLine = GetComponent<LineRenderer>();
gunAudio = GetComponent<AudioSource>();
}
void Update ()
{
if (Input.GetButtonDown("Fire1") && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
StartCoroutine (ShotEffect());
Vector3 rayOrigin = fpsCam.ViewportToWorldPoint (new Vector3(0.5f, 0.5f, 0.0f));
RaycastHit hit;
Debug.DrawRay(transform.position, rayOrigin, Color.green);
laserLine.SetPosition (1, gunEnd.position);
if (Physics.Raycast (rayOrigin, fpsCam.transform.forward, out hit, weaponRange))
{
laserLine.SetPosition (0, hit.point);
ShootableBox health = hit.collider.GetComponent<ShootableBox>();
if (health != null)
{
health.Damage (gunDamage);
}
if (hit.rigidbody != null)
{
hit.rigidbody.AddForce (-hit.normal * hitForce);
}
}
else
{
laserLine.SetPosition (1, rayOrigin + (fpsCam.transform.forward * weaponRange));
}
}
}
private IEnumerator ShotEffect()
{
gunAudio.Play ();
laserLine.enabled = true;
yield return shotDuration;
laserLine.enabled = false;
}
}
@spacechicken27 I had the same error, but I think I fixed it. Try and change the size under Positions on you're Line Renderer to 2. This fixed the error for me.
Having the same issue, and now I'm giving up on searching for answers for now, because this is just aggrivating. I did what you said, nothing really changed.
Are you sure you read JustNatBros's answer? spacechicken27 seems to be a bad observer as what he describes sounds like he actually did change the point count at runtime which made the error go away during the play session but when he stopped it was back to the original value.
You posted an answer but you did not answer the question. You should have posted a comment.
Well, When messing around I added a mesh collider to my gun and made sure the gunEnd was far enough away from the gun, and it worked... somehow. I did not change any code.
IMPORTANT REVISION!! after just playing with it for a few minutes seeing how it behaved when I aimed in different ways, I stopped running the program, ran it again, and the error appeared again!!! i did not change anything!
