detect pickupable item via camera raycast

i'm struggling with finding anything that works. I need to make a system that sends a raycast from the center of the camera view to detect a specific layer, "pickupable", and then note down the game object.

here's my current code (which doesn't work)

Code (CSharp):

1.    
2.     public Camera camera;
3.     public GameObject itemPicked;
4.  
5.     public float pickupRange;
6.     public LayerMask pickupable;
7.    
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         camera = GetComponent<Camera>();
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.         Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
18.        
19.         RaycastHit hit;
20.         if (Physics.Raycast(ray, out hit, pickupRange) && hit.transform.gameObject.layer ==          LayerMask.NameToLayer("pickupable"))
21.         {
22.             Debug.DrawLine(ray.origin, Camera.main.transform.forward * 50000000, Color.red);
23.  
24.             print("I'm looking at an item" + hit.transform.name);
25.  
26.             itemPicked = hit.transform.gameObject;
27.         }
28.  
29.         else
30.         {
31.             print("I'm looking at nothing!");
32.  
33.             itemPicked = null;
34.         }
35.     }

 

nvm lol fixed it
