In this unity C# code, where could I use bitwise operations?
```
using UnityEngine;
using UnityEngine.Events;

public class Collectable : MonoBehaviour
{
    public enum TypePreset { Custom, Star, Hexagon}
    public TypePreset Type;
    [Tooltip("All with same name MUST be the same with capitals.")]
    public string NameOfCollectable;
    [Tooltip("Best to leave this unchecked.")]
    public bool Collected = false;
    [Tooltip("What happens upon collection.")]
    public UnityEvent OnCollection;    [Min(0)] public int AddScore;

    private void OnTriggerEnter2D(Collider2D C)
    {
        if (!Collected && C.gameObject.layer.Equals(6))
        {
            Collected = true;
            OnCollection.Invoke();
            var S = FindObjectOfType<SetLevelData>();
            if (AddScore > 0 && S)
            { S.AddScore(AddScore); }
            if (Type == TypePreset.Star)
            { PlayerData.CurrentPlayer.SaveData.AddStar(); }
        }
    }
}
```
