NullReferenceException: Object reference not set to an instance of an object

[Kameen_Avery]

Hello,

I am on Raycasting For Components of the 2019 RPG Core Combat Creator: Learn Intermediate Unity C# Coding.

I did the code as in the video but am getting a Null reference in my InteractWithCombat code in the PlayerController.

Here is what I am working with

PlayerController.cs :
public class PlayerController : MonoBehaviour {

    private void Update()
    {
        InteractWithCombat();
        InteractWithMovement();
    }

    private void InteractWithCombat()
    {
        RaycastHit[] hits = Physics.RaycastAll(GetMouseRay());
        foreach (RaycastHit hit in hits)
        {
            CombatTarget target = hit.transform.GetComponent<CombatTarget>();
            if(target == null) continue;

            if (Input.GetMouseButtonDown(0))
            {
               GetComponent<Fighter>().Attack(target); 
            }
        }
    }

    private void InteractWithMovement()
    {
        if (Input.GetMouseButton(0))
        {
            MoveToCursor();
        }
    }

    private void MoveToCursor()
    {
        RaycastHit hit;
        bool hasHit = Physics.Raycast(GetMouseRay(), out hit);
        if (hasHit)
        {
            GetComponent<Mover>().MoveTo(hit.point);
        }
    }

    private static Ray GetMouseRay()
    {
        return Camera.main.ScreenPointToRay(Input.mousePosition);
    }
} 

Fighter.cs
public class Fighter : MonoBehaviour
{
public void Attack(CombatTarget target)
{
print(“Take that you short, squat peasant!”);
}
}

NullReferenceException: Object reference not set to an instance of an object
RPG.Control.PlayerController.InteractWithCombat () (at Assets/Scripts/Control/PlayerController.cs:25)
RPG.Control.PlayerController.Update () (at Assets/Scripts/Control/PlayerController.cs:11)

what is weird is that when I originally started the project a month or so ago this worked just fine, but now it is not working. I just cant see where I went wrong

Hi @Kameen_Avery, I can’t seem to see any issues with the code from what I gather GetComponent().Attack(target); is line 25, does the gameObject with the PlayerController have a Fighter on it?

[Kameen_Avery]

Hey there, so Fighter is attached to the Player along with CombatTarget attached to the Enemy.

I even went as far as to copy paste the code from Github to see if that would work no dice.

I am not even allowed to move anywhere. Movement is completely dead.

[Kameen_Avery]

So, after moving on to the next video, I realize that he corrects this later in the video Canceling Combat with Movement.

What really sucks is I spent a day trying to figure out where I went wrong and could not figure it out. This bodes ill for my future debugging…
