NULL REFERENCE DRVING ME INSANE!!! HELP!!!!

Questions & Answers
1

I am trying to make my gun rapid fire in my game. Every time I press start it throws me a Null Reference Exception here is my code. It was working fine in previous versions of unity but I decided to try the beta of 5.6 and I am now getting this error. The error is on line 26. Thanks :).

using UnityEngine;
using UnityEngine.Networking;

[RequireComponent(typeof(WeaponManager))]
public class PlayerShoot : NetworkBehaviour {

private const string PLAYER_TAG = "Player";

private PlayerWeapon currentWeapon;

[SerializeField]
private Camera cam;

[SerializeField]
private LayerMask mask;

private WeaponManager weaponManager;

void Start ()
{
	if (cam == null) {
		Debug.LogError ("PlayerShoot: No camera referenced!");
		this.enabled = false;
	}

	weaponManager = GetComponent<WeaponManager> ();
}

void Update ()
{
	currentWeapon = weaponManager.GetCurrentWeapon ();

	if (currentWeapon.fireRate <= 0f) {
		if (Input.GetButtonDown ("Fire1")) {
			Shoot ();
		}
	} else {
		if (Input.GetButtonDown ("Fire1")) {
			InvokeRepeating ("Shoot", 0f, 1f / currentWeapon.fireRate);
		} else if (Input.GetButtonUp ("Fire1")) {
			CancelInvoke ("Shoot");
		}
	}
}

[Client]
void Shoot ()
{
	RaycastHit _hit;
	if (Physics.Raycast (cam.transform.position, cam.transform.forward, out _hit, currentWeapon.range, mask)) {
		if (_hit.collider.tag == PLAYER_TAG) {
			CmdPlayerHit (_hit.collider.name, currentWeapon.damage);
		}
	}
}

[Command]
void CmdPlayerHit (string _playerID, int _damage)
{
	Debug.Log (_playerID + " has been shot.");

	PlayerManager _player = GameController.GetPlayer (_playerID);
	_player.RpcTakeDamage (_damage);
}

}

The currentWeapon variable has nothing assigned to it.

Maybe the GetCurrentWeapon() method could not initialize the variable. Check the WeaponManager class if the method can return a PlayerWeapon variable.

If you could not find the problem, you should include the class here.
