public class C_Shell : MonoBehaviour
{
public GameObject shellObject;

    public float timealive;

    public Vector3 velocity;
    public Vector3 position;
    public Vector3 lastPosition;

    public readonly float mass;
    public readonly float drag;
    public readonly float force;
    public readonly float deflectionAngle;

    public C_Shell(GameObject _shellObject, ShellConstants _shellConstants, Vector3 _position, Vector3 _velocity)
    {
        this.shellObject = _shellObject;
        this.mass = _shellConstants.mass;
        this.drag = _shellConstants.drag;
        this.force = _shellConstants.force;
        this.deflectionAngle = _shellConstants.deflectionAngle;
        this.position = _position;
        this.velocity = _velocity;
    }

    private void Awake()
    {
        Debug.Log("no way man omg");
    }

    private void UpdateVelocity()
    {
    }

    private void UpdatePosition()
    {
    }

    public void UpdateObject()
    {
        this.UpdateVelocity();
        this.UpdatePosition();
    }
}

public class Shell_Manager : MonoBehaviour
{
    public static Shell_Manager instance;
    public List<C_Shell> shells;
    public float deleteTime = 3.0f;

    private void Awake()
    {
        if (instance == null)
            instance = this;
    }
    private void FixedUpdate()
    {
        UpdateShells();
    }
    private void UpdateShells()
    {
        for (int i = 0; i < shells.Count; i++)
        {
            if (shells*.timealive >= deleteTime)*

{
Destroy(shells*.shellObject);*
shells.RemoveAt(i);
continue;
}
shells*.timealive += Time.fixedDeltaTime;*
shells*.UpdateObject();*
}
}
// this func is being called too
void Fire_AP(ShellFire shell)
{
Object prefab = AssetDatabase.LoadAssetAtPath(“Assets/Resources/Prefabs/Shell.prefab”, typeof(GameObject));

shells.Add(new C_Shell(Instantiate(prefab, shell.initialPosition, shell.initialAngle) as GameObject, C_AP.constants, shell.initialPosition, shell.initialDirection));
}
}
I dont know why instance of C_Shell doesnt call Awake or any other method in class

A MonoBehaviour script must be attached to some GameObject to get its Awake, Update, etc. methods executed. The engine sends a message to a GameObject, and the object sends a message to its components (attached scripts) to execute the methods: Awake and Start when the object is activated in the scene, Update when the engine says “Hey, it’s your turn to do your stuff in this frame”.
You probably didn’t attach them to anything.
