LineRenderer Raycast Gun Bug
I have an issue with the LineRenderer component and when I try to implement it into script so that it acts as a visible ray.
Heres the code of the gun that fires the ray:
using UnityEngine; using System.Collections;
[RequireComponent (typeof (AudioSource))] public class dev_ray_shoot : MonoBehaviour {
public enum GunType {Semi,Burst,Auto};
public GunType gunType;
public float rpm;
//Components
public Transform rayExit;
private LineRenderer tracer;
//System
private float secondsBetweenShots;
private float nextPossibleShootTime;
void Start() {
secondsBetweenShots = 60/rpm;
if (GetComponent<LineRenderer>()){
tracer = GetComponent<LineRenderer>();
}
}
public void Shoot() {
if (CanShoot()){
Ray ray = new Ray(rayExit.position,rayExit.forward);
RaycastHit hit;
float rayDistance = 20;
if (Physics.Raycast(ray,out hit, rayDistance = 20)){
rayDistance = hit.distance;
}
nextPossibleShootTime = Time.time + secondsBetweenShots;
AudioSource audio = GetComponent<AudioSource> ();
audio.Play();
if (tracer){
StartCoroutine("RenderTracer", ray.direction * rayDistance);
}
Debug.DrawRay (ray.origin,ray.direction * rayDistance, Color.red, 1);
}
}
public void Shoot_Automatic () {
if (gunType == GunType.Auto) {
Shoot ();
}
}
private bool CanShoot() {
bool canShoot = true;
if (Time.time < nextPossibleShootTime) {
canShoot = false;
}
return canShoot;
}
IEnumerator RenderTracer(Vector3 hitPoint){
tracer.enabled = true;
tracer.SetPosition(0,rayExit.localPosition);
tracer.SetPosition(1,rayExit.localPosition + hitPoint);
yield return null;
tracer.enabled = false;
}
}
The linerenderer component which is attatched to the same gameobject as this script does not fully follow the ray the way its supposed to. So can someone please help? I have a picture of it:
(The yellow line is the linerenderer and the red line is the debug.drawray) for extra information, the LineRenderer deforms when I fire in different directions, it changes its length each time.
Please help, thank you.
P.S. Im using Unity 5
Instead of:
tracer.SetPosition(1,rayExit.localPosition + hitPoint);
Try:
tracer.SetPosition(1,rayExit.position + ray.direction * hit.distance);
If I just change that it will say the variables are missing/unkown in the current context, due to the those things being declared only in the Update, not in the IEnumerator RenderTracer.
If I add them at the top (after the "$$anonymous$$onobehaviour {" ) where most variables are then it accepts the script but the linerenderer just disappears somewhere unknown.
So it doesn't fully work.
For point 0 replace localPosition with position, too.
tracer.SetPosition(0,rayExit.position);
Nope, I set both to have position ins$$anonymous$$d of localPosition and replaced the HitPoint stuff, also added Ray ray, RaycastHit hit at the top of the code with the other variables, but like last time it just disappears.
for extra information, the LineRenderer deforms when I fire in different directions, it changes its length each time.
