Object Reference Issue

[opal basin]

Hello There, I Am Currently Following A Tutorial On How To Make A Multiplayer Game In Unity Using Photon.

When I Try And Shoot At The Player, I Get This Error Message

Here Is The Code For SingleShotCode.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SingleShotGun : Gun
{
    [SerializeField] Camera cam;

    public override void Use()
    {
        Shoot();
    }

    void Shoot()
    {
        Ray ray = cam.ViewportPointToRay(new Vector3(0.5f, 0.5f));
        ray.origin = cam.transform.position;
        if (Physics.Raycast(ray, out RaycastHit hit))
        {
            hit.collider.gameObject.GetComponent<IDamageable>().TakeDamage(((GunInfo)itemInfo).damage);
        }
    }
}

Assuming line 20 is the one where you apply the damage.
Either what you hit did not have a script implementing IDamageable attached to it, or itemInfo did not have a value

it was when i tried shooting at a other player that error would show up

Identify what is null. Then take debugging steps to see why it's the case (log the name of the object you hit)

Should probably be using TryGetComponent since you do not filter out the raycast results with a layer mask for example.

if (Physics.Raycast(..., out RaycastHit hit) && hit.collider.GetComponent(out IDamageable dmg))
{
    dmg.TakeDamage(stuff);
}
else
{
    // No hit or not damageable, handle
}

is it possible for a preview of what the code will look like from the code of the first message i sent or no ?
