can i reference a script contained in a different namespace?

Question

I have 3 folders in my project, named scripts, photon and standard assets. Now I need to make a reference from the standard assets folder to a script in the 'scripts' folder, which is possible only if I copy the folder into the standard assets(because it has a different namespace).But I get an error with the photon.So is there a way to make a reference without copying the folder?

 using UnityEngine;
 namespace UnityStandardAssets.CrossPlatformInput
{
public class ButtonHandler : MonoBehaviour
{  
  public  wepScript  ws; //error cannot find  wepScript 
}
}


  using UnityEngine;
  using System.Collections;

 public class wepScript : MonoBehaviour {
                   }

Actually, namespace is not something related to the Unity. You can use whatever namespace or code in your classeses. You just need to include the namespace via using.

using UnityEngine;
using System.Collections;

For example: I have a script under Standard Assets folder called Weapon.

using UnityEngine;
namespace FooNamespace
{
    public class Weapon : MonoBehaviour {

        public void LogMeUp()
        {
            Debug.Log("I have been called");
        }
    }
}

And then, I have GonnaCallWeapon script somewhere else.

using UnityEngine;

using FooNamespace;

public class GonnaCallWeapon : MonoBehaviour {
    public Weapon weapon;
    void Start () {
        weapon.LogMeUp();
        Debug.Log("I called LogMeUp");
    }
}

• I have attached my Weapon, and GonnaCallWeapon scripts to an object in the hierarchy, and set up the weapon variable.
