Untiy Photon Networking Shoot Script

Hi i was wondering were i can find some shoot script for photon i have been using some from a tutorial on youtube but i dont like it it doesn’t always kill the other player.
using UnityEngine;
using System.Collections;

public class PlayerShooting : MonoBehaviour {

	public float fireRate = 0.5f;
	float cooldown = 0;
	public float damage = 25f;
	FXManager fxManager;

	void Start() {
		fxManager = GameObject.FindObjectOfType<FXManager>();

		if(fxManager == null) {
			Debug.LogError("Couldn't find an FXManager.");
		}
	}

	// Update is called once per frame
	void Update () {
		cooldown -= Time.deltaTime;

		if(Input.GetButton("Fire1")) {
			// Player wants to shoot...so. Shoot.
			Fire ();
		}

	}

	void Fire() {
		if(cooldown > 0) {
			return;
		}

		Debug.Log ("Firing our gun!");

		Ray ray = new Ray(Camera.main.transform.position, Camera.main.transform.forward);
		Transform hitTransform;
		Vector3   hitPoint;

		hitTransform = FindClosestHitObject(ray, out hitPoint);

		if(hitTransform != null) {
			Debug.Log ("We hit: " + hitTransform.name);

			// We could do a special effect at the hit location
			// DoRicochetEffectAt( hitPoint );

			Health h = hitTransform.GetComponent<Health>();

			while(h == null && hitTransform.parent) {
				hitTransform = hitTransform.parent;
				h = hitTransform.GetComponent<Health>();
			}

			// Once we reach here, hitTransform may not be the hitTransform we started with!

			if(h != null) {
				// This next line is the equivalent of calling:
				//    				h.TakeDamage( damage );
				// Except more "networky"
				PhotonView pv = h.GetComponent<PhotonView>();
				if(pv==null) {
					Debug.LogError("Freak out!");
				}
				else {
					h.GetComponent<PhotonView>().RPC ("TakeDamage", PhotonTargets.AllBuffered, damage);
				}

			}

			if(fxManager != null) {
				fxManager.GetComponent<PhotonView>().RPC ("SniperBulletFX", PhotonTargets.All, Camera.main.transform.position, hitPoint);
			}
		}
		else {
			// We didn't hit anything (except empty space), but let's do a visual FX anyway
			if(fxManager != null) {
				hitPoint = Camera.main.transform.position + (Camera.main.transform.forward*100f);
				fxManager.GetComponent<PhotonView>().RPC ("SniperBulletFX", PhotonTargets.All, Camera.main.transform.position, hitPoint);
			}

		}

		cooldown = fireRate;
	}

	Transform FindClosestHitObject(Ray ray, out Vector3 hitPoint) {

		RaycastHit[] hits = Physics.RaycastAll(ray);

		Transform closestHit = null;
		float distance = 0;
		hitPoint = Vector3.zero;

		foreach(RaycastHit hit in hits) {
			if(hit.transform != this.transform && ( closestHit==null || hit.distance < distance ) ) {
				// We have hit something that is:
				// a) not us
				// b) the first thing we hit (that is not us)
				// c) or, if not b, is at least closer than the previous closest thing

				closestHit = hit.transform;
				distance = hit.distance;
				hitPoint = hit.point;
			}
		}

		// closestHit is now either still null (i.e. we hit nothing) OR it contains the closest thing that is a valid thing to hit

		return closestHit;

	}
}

What is the tutorial you are following?
