Hello, I am trying to make a multiplayer fps, but my damaging/kill system deosn’t work… The raycasts seem to not function because I get this error. NullReferenceException: Object reference not set to an instance of an object
shoot_handle.shoot (UnityEngine.Vector3 pos, UnityEngine.Vector3 rot, System.Int32 dmg) (at Assets/POLYGON - FPS free/scripts/shoot_handle.cs:156)
shoot_handle.Update () (at Assets/POLYGON - FPS free/scripts/shoot_handle.cs:59)
Here is the part of the script that isn’t working:

void Update()
{
   

        foreach (add_shoot s in added_shoots)
        {

            shoot(s.pos, s.rot, s.dmg);
        }

        added_shoots.Clear();
    
}

In general questions about NullreferenceExceptions are forbidden in here. Please solve them on your own next time. There is an extreme amount of info on this out there.
The problem you have here that one element in your list “added_sheets” is null. This way you cannot access the position/rotation/damage of null in line 9.
