So, I have a character that turns to the right or left depending on where the mouse is on the screen, and when they're turned right, OnTriggerStay2D works for a second and then stops. I have no idea what is causing this. Here is my code for the player and the OnTriggerEnter2D script:

region variables

public float jumpHeight = 5; public float moveSpeed; public float maxSpeed; public Rigidbody2D rb; #endregion variables

 void Update () {

     //float horizontal = Input.GetAxis("Horizontal") * moveSpeed;

     //rb.AddForce(transform.right * horizontal);

     if (Input.GetKeyDown(KeyCode.Space) && rb.velocity.y == 0)
     {
         rb.AddForce(transform.up * jumpHeight);
     }


     if (rb.velocity.magnitude > maxSpeed)
     {
         rb.velocity = rb.velocity.normalized * maxSpeed;
     }

     Vector2 mouse = new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y);

     if (mouse.x < Screen.width / 2)
     {
         transform.rotation = Quaternion.Euler(0, 180, 0);

         #region movement
         if (Input.GetKey("d"))
         {
             rb.AddForce(-transform.right * moveSpeed);
         }

         if (Input.GetKey("a"))
         {
             rb.AddForce(transform.right * moveSpeed);
         }

         if (Input.GetKeyUp("d"))
         {
             rb.velocity = Vector2.zero;
         }

         if (Input.GetKeyUp("a"))
         {
             rb.velocity = Vector2.zero;
         }
         #endregion movement
     }

     if (mouse.x > Screen.width / 2)
     {
         transform.rotation = Quaternion.Euler(0, 0, 0);

         #region movement
         if (Input.GetKey("d"))
         {
             rb.AddForce(transform.right * moveSpeed);
         }

         if (Input.GetKey("a"))
         {
             rb.AddForce(-transform.right * moveSpeed);
         }

         if (Input.GetKeyUp("d"))
         {
             rb.velocity = Vector2.zero;
         }

         if (Input.GetKeyUp("a"))
         {
             rb.velocity = Vector2.zero;
         }
         #endregion movement
     }

public float speed = 10; public Transform player; public Transform elevator; public Transform starship; public int floorLevel = 4;

 void OnTriggerStay2D (Collider2D c)
 {

     Debug.Log("testing testing 123 can you hear me let me see");

     if (c.tag == "Player")
     {
         player.parent = elevator;

         #region down
         if (Input.GetKeyDown("s") && floorLevel == 1)
         {
             Debug.Log("You can't go down any further!");
         }
         if (Input.GetKeyDown("s") && floorLevel == 2)
         {
             floorLevel = 1;
         }
         if (Input.GetKeyDown("s") && floorLevel == 3)
         {
             floorLevel = 2;
         }
         if (Input.GetKeyDown("s") && floorLevel == 4)
         {
             floorLevel = 3;
         }
         #endregion down

         #region up
         if (Input.GetKeyDown("w") && floorLevel == 4)
         {
             Debug.Log("You can't go up anymore!");
         }
         if (Input.GetKeyDown("w") && floorLevel == 3)
         {
             floorLevel = 4;
         }

         {
             floorLevel = 2;
         }
         #endregion up
     }
 }

 void OnTriggerExit2D ()
 {
     player.parent = starship;
 }
