Question Cannot be accessed with an instance reference; qualify it with a type name instead?

Hello there I am a beginner user
So I was trying to make a pickup code. without the "CurrentObject.constraints.FreezeRotation = false;"
It was working as intended, but I want to lock the rotation physic object that has been picked up. but, I got this error instead: Member 'RigidbodyConstraints.FreezeRotation' cannot be accessed with an instance reference; qualify it with a type name instead. How can I fix this? Thank you

Code (CSharp):

1. using System.Collections;
2. using UnityEngine.InputSystem;
3. using UnityEngine;
4. namespace StarterAssets
5.  
6. {
7. public class PickupScript : MonoBehaviour
8. {
9.     [SerializeField] private LayerMask PickupMask;
10.     [SerializeField] private Camera PlayerCam;
11.     [SerializeField] private Transform PickupTarget;
12.     [Space]
13.     [SerializeField] private float PickupRange;
14.     private Rigidbody CurrentObject;
15.  
16.  
17.         void Start()
18.         {
19.             animator = GetComponent<Animator>();
20.         }
21.     public void OnInteraction(InputValue value)
22.     {
23.         {
24.             if(CurrentObject)
25.             {
26.                 CurrentObject.useGravity = true;
27.                 CurrentObject = null;
28.                 [I]CurrentObject.constraints.FreezeRotation = true;[/I]
29.                 return;
30.             }
31.  
32.             Ray CameraRay = PlayerCam.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
33.             if (Physics.Raycast(CameraRay, out RaycastHit HitInfo, PickupRange, PickupMask))
34.             {
35.                 CurrentObject = HitInfo.rigidbody;
36.                 CurrentObject.useGravity = false;
37.                 [I]CurrentObject.constraints.FreezeRotation = true;[/I]
38.                 }
39.         }
40.     }
41.  
42.     void FixedUpdate()
43.     {
44.         if(CurrentObject)
45.         {
46.             Vector3 DirectionToPoint = PickupTarget.position - CurrentObject.position;
47.             float DistanceToPoint = DirectionToPoint.magnitude;
48.             CurrentObject.velocity = DirectionToPoint * 12f * DistanceToPoint;
49.         }
50.     }
51. }

Console:
PickupScript.cs(41,17): error CS0176: Member 'RigidbodyConstraints.FreezeRotation' cannot be accessed with an instance reference; qualify it with a type name instead

 

If you want to freeze the rotation, you need to follow how to do it. https://docs.unity3d.com/ScriptReference/RigidbodyConstraints.html

Looks like if you want to freeze rotation, you actually need to do.

Code (CSharp):

1. CurrentObject.constraints = RigidbodyConstraints.FreezeRotation;
