Hello there Unity Community!

So I have a gun shooting script I made here:

			if (lastShot <= Time.time) {
				RaycastHit hit = new RaycastHit();
				//AudioSource.PlayClipAtPoint(gunSound, transform.position);
				audio.Play();
				//Debug.DrawRay(transform.Find("BulletSpawn").position, transform.Find("BulletSpawn").TransformDirection(Vector3.forward));
				if (Physics.Raycast(transform.Find("BulletSpawn").position, transform.Find("BulletSpawn").TransformDirection(Vector3.forward), out hit)) {
					if (hit.distance < distance) {
						hit.transform.GetComponent<PhotonView>().RPC("ApplyDamage", PhotonTargets.All, damage);
						//hit.transform.SendMessage("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
					} else {
						//Raycast is a null. (hit terrtain);
					}
				}
				lastShot = Time.time + fireRate;
			}

And when I deicde to shoot the terrain (nothing really) then it will give me an error on this line:

hit.transform.GetComponent<PhotonView>().RPC("ApplyDamage", PhotonTargets.All, damage);

Because my hit (RaycastHit) is not hitting any object, it is returning a null which is basically sending the object null “ApplyDamage”.
How can I do a simple if statement to check if the Raycast doesn’t hit anything so I can not send a “ApplyDamage” to that null object.

My guess is that you are hitting a collider on an object that does not have a ‘PhotonView’ component. You can put a Debug.Log() inside the raycast that outputs the name and tag of the hit object to verify. One fix is to check for a null reference of the component;

PhotonView pv = hit.transform.GetComponent<PhotonView>();
if (pv != null) {
    pv.RPC("ApplyDamage", PhotonTargets.All, damage);
}
