Detecting when player isn't grounded when the ground disappears?

Question

I'm making a 2D platformer and I have platforms that disappear when the player stands on it. To detect wether the character is grounded I use OnCollisionStay2D and OnCollisionExit2D. The problem is that OnCollisionExit2D doesn't fire when the platform disappears. I'm trying to find a way to always detect the player's collision, even if it isn't colliding with anything. That way if it isn't colliding with anything I could detect that. Is there anyway to do that? Or to make OnTriggerExit2D fire when the object is disabled? This is the relevant code: //The solution I'm trying to implement void OnUpdate() { foreach(ContactPoint2D contact in rb.GetComponent().contacts) { if(contact.normal == new Vector2(0, 1)) { print("grounded"); } } }

 //The Ground detection. This works fine except for the case mentioned above
 
   private void OnCollisionStay2D(Collision2D collision)
     {
         foreach (ContactPoint2D contact in collision.contacts)
         {
             if (contact.normal == new Vector2(0, 1))
             {
                 isGrounded = true;
                 break;
             }
             else
             {
                 isGrounded = false;
             }
         }
     }
 
     private void OnCollisionExit2D(Collision2D collision)
     {
         isGrounded = false;
     }

I found a solution. Here it is for anyone who is curious. //Get the contacts the player is touching private void OnCollisionStay2D(Collision2D collision) { contacts = collision.contacts; }

 //checks the number of contacts. If the number is 0 it means it isn't touching anything
 
 void Update()
      {
                      if(contacts != null)
         {
             if (rb.GetContacts(contacts) == 0)
             {
                 touchesLeftWall = false;
                 touchesRightWall = false;
                 isGrounded = false;
             }
         }
       }
