Call a function from other script in C# unity3D

I have a script with a public function which sets up an animation trigger like this:

public class AnimationManager : MonoBehaviour {

    public Animator menuAnim;

    void Start () {
        menuAnim = GetComponent<Animator>();
    }

    public void Test() {
        menuAnim.SetTrigger("Fade");
    }
}

Now in a different gameObject i have another script that i want to simply call the function Test. So i made a script that did this:

public class Testing : MonoBehaviour {

   void begin(){
     AnimationManager.Test();
   // other stuff
   }
 }

But this leads to this error:

 An object reference is required to access non-static member `AnimationManager.Test()'

The error occurs in the first line of the begin function.

I am new ish to C# i originally learnt Javascript, so i am a bit confused how i would reference the member in order to call this function.

Hope you can help.

Basically you could use a static helper class to set things for the animator:

public class AnimationManager : MonoBehaviour {

    public Animator menuAnim;

    void Start () 
    {
            menuAnim = GetComponent<Animator>();
    }

    public void Test() 
    {
        AnimationHelper.Test(menuAnim);
    }
}

public class Testing : MonoBehaviour 
{
   void begin()
   {
    Animator menuAnim = GetComponent<Animator>();
    AnimationHelper.Test(menuAnim);
   }
}

public static AnimationHelper
{
    public static void Test(Anímation animation)
    {
        animation.SetTrigger("Fade");
    }
}

This won't really work since your AnimationManager class isn't static, you need to initialize it first like this:

AnimationManager someName = new AnimationManager();
someName.Test();

And take note they must have the same namespace, if not, you still need to add the namespace in the using directive.

Edited:

public static class AnimationManager : MonoBehaviour {

    public Animator menuAnim;

    static void Start () {
        menuAnim = GetComponent<Animator>();
    }

    public static void Test() {
        menuAnim.SetTrigger("Fade");
    }
}

This is how you're gonna call it:

public class Testing : MonoBehaviour {

   void begin(){
     AnimationManager.Test(); //since your AnimationManager class is already static
//you don't need to instantiate it, just simply call it this way
   // other stuff
   }
 }
