not getting direction of view to push objects (AddForce)

Hi all, sorry for messy code, ... I´m new to this.

I´m using the FPSController, and I want to push Objects into the direction I´m lookin to. But my scripts/setups only keeps shooting/pushing them into one single direction.

I tried different versions but I cant manage to get it work. The scene Setup explanation: the "_ScriptStack", is a (empty) GameObject containing all the Scripts except "Raycaster"-Script. Raycaster-Script is on "FirstPersonCharacter".

(I wanted to have all the scripts on one spot(_ScriptStack). But I didn´t get the raycast to work as long it was not on the "FirstPersonCharacter".)

Please hint me to the right direction ;D And perhaps you could give some critics on how I have build this up or how one should build things up. Btw, I´m trying to do a FirstPerson meele-combat game, like: http://store.steampowered.com/app/219640/ (Chivalry).

Short: How to get looking/aiming Direction for AddForce?

Raycaster Script: using UnityEngine; using System.Collections;

 public class Raycaster : MonoBehaviour {
 
     public Weapon _weapon; //length of weapon&ray from Weapon.cs
     public FightSystem _fightSys;
 
     public RaycastHit rayInfo;
 
     public Vector3 fwd;
     public bool rayHitDetection;
     public float rayDistance;
     public string rayHitObjectName;
 
 
     // Use this for initialization
     void Start ()
     {
         //shortcut to the GameObject containing the Weapon.cs, not needed when on same GameObject
         _weapon = GameObject.Find("_ScriptStack").GetComponent<Weapon>();
         _fightSys = GameObject.Find("_ScriptStack").GetComponent<FightSystem>();
     }
     
     // Update is called once per frame
     void Update ()
     {
         //declaring a forward looking vector(?)
         fwd = transform.TransformDirection(Vector3.forward) * _weapon.wLength;
         Debug.DrawRay(transform.position, fwd, Color.green);
 
         //Shoots a ray, wether object is in range or not!
         if (Input.GetMouseButtonDown(0) && (Physics.Raycast(transform.position, fwd, out rayInfo, _weapon.wLength)))
         {
             //set rayVariables to make calling them easier
             //!!!bool to int!!!! rayInfo = rayHitDetection;
             rayDistance = rayInfo.distance;
             rayHitObjectName = rayInfo.collider.name;
             Debug.Log("ObjName: " + rayHitObjectName);
             Debug.Log("rayDistance: " + rayDistance);
 
             _fightSys.Attack();
 
         }
         else
         {
             //MISS
             if(Input.GetMouseButtonDown(0) && (!Physics.Raycast(transform.position, fwd, out rayInfo, _weapon.wLength)))
             Debug.Log("nuttin in range");
         }
     }
 }

FightSystem-Script:

 using UnityEngine;
 using System.Collections;
 
 public class FightSystem : MonoBehaviour {
 
     public Weapon _weapon;
     public Raycaster _ray;
     public Raycaster _fwd;
 
     // Use this for initialization
     void Start ()
     {
         _weapon = GameObject.Find("_ScriptStack").GetComponent<Weapon>();
         _ray = GameObject.Find("FPSController").GetComponentInChildren<Raycaster>();
         _fwd = GameObject.Find("FPSController").GetComponentInChildren<Raycaster>();
     }
     
     // Update is called once per frame
     void Update ()
     {
         Debug.Log(_ray.transform.position);
     }
 
     public void Attack()
     {
         //Punch the Object, but only Objects which have a rigidbody.
         if (_ray.rayInfo.rigidbody != null)
         {
             //_ray.rayInfo.rigidbody.AddForceAtPosition(transform.forward * _weapon.wDamage, _ray.rayInfo.point); //ADDFORCE change direction
             _ray.rayInfo.rigidbody.AddForceAtPosition(_fwd.transform.position * _weapon.wDamage, _ray.rayInfo.point); //ADDFORCE change direction
         }
     }
     //damage the enemy which is infront of you
     //swing your weapon/play anim (perhaps do some refuel time)
     //give points or shit
 }
 

Thanks for letting me bother you wise-guys! :)

EDIT: I made it work, but I don´t know why. Really great -.- I had it tested with "Camera.main.transform.forward" and it didn´t work. But now it does! Really strange. For others, who may have the same problem, here my solution: using UnityEngine; using System.Collections;

 public class Raycaster : MonoBehaviour {
 
     public Weapon _weapon; //length of weapon&ray from Weapon.cs
     public FightSystem _fightSys;
 
     public RaycastHit rayInfo;
 
     public bool rayHitDetection;
     public float rayDistance;
     public string rayHitObjectName;
 
 
     // Use this for initialization
     void Start ()
     {
         //shortcut to the GameObject containing the Weapon.cs, not needed when on same GameObject
         _weapon = GameObject.Find("_ScriptStack").GetComponent<Weapon>();
         _fightSys = GameObject.Find("_ScriptStack").GetComponent<FightSystem>();
     }
     
     // Update is called once per frame
     void Update ()
     {
         //declaring a forward looking vector(?)
         Vector3 fwd = transform.TransformDirection(Vector3.forward) * _weapon.wLength;
         Debug.DrawRay(transform.position, fwd, Color.green);
 
         //Shoots a ray, wether object is in range or not!
         if (Input.GetMouseButtonDown(0) && (Physics.Raycast(transform.position, fwd, out rayInfo, _weapon.wLength)))
         {
             //set rayVariables to make calling them easier
             //!!!bool to int!!!! rayInfo = rayHitDetection;
             rayDistance = rayInfo.distance;
             rayHitObjectName = rayInfo.collider.name;
             Debug.Log("ObjName: " + rayHitObjectName);
             Debug.Log("rayDistance: " + rayDistance);
 
             _fightSys.Attack();
 
         }
         else
         {
             //MISS
             if(Input.GetMouseButtonDown(0) && (!Physics.Raycast(transform.position, fwd, out rayInfo, _weapon.wLength)))
             Debug.Log("nuttin in range");
         }
     }
 }
