Look Rotation viewing vector is zero. Raycast problem
Hello I am having an issue with my unity project. The problem is every time I "shoot" a probuilder cube it says "Look Rotation viewing vector is zero" it brings me to the Shoot() function I made
private void Shoot()
{
bang.Play();
readyToShoot = false;
//Spread
float x = Random.Range(-spread, spread);
float y = Random.Range(-spread, spread);
//Calculate Direction with Spread
Vector3 direction = FPSCam.transform.forward + new Vector3(x, y, 0);
//RayCast
if (Physics.Raycast(FPSCam.transform.position, FPSCam.transform.forward, out rayHit, range, whatIsEnemy))
{
Debug.Log(rayHit.collider.name);
if (rayHit.collider.CompareTag("Enemy"))
{
rayHit.collider.GetComponent<Enemy>().TakeDamage(damage);
}
}
Instantiate(bulletHoleGraphic, rayHit.point, Quaternion.LookRotation(rayHit.normal));
bulletsLeft--;
bulletsShot--;
Invoke("ResetShot", timeBetweenShooting);
if (bulletsShot > 0 && bulletsLeft > 0)
Invoke("Shoot", timeBetweenShots);
}
you use rayHit in the Instantiate method place and align the rotation but you don't make sure the Raycast actually hits something when Instantiating. Move the Instantiate inside the if(Raycast...{ } clause and it should be ok.
