Question How should I convert a 'method group' ground check into a boolean?

(Been waiting for awhile on moderation in Unity Answers, so I thought I'd try asking the question here as well) I've been working on a 2D ground check for a simple platformer game and I'm running into difficulties using the check itself, here's the code I have:

Code (CSharp):

1.      private bool jumpKeyWasPressed;
2.      private Rigidbody2D rigidbodyComponent;
3.      private BoxCollider2D groundColl;
4.    
5.      [SerializeField] private float jumpHeight = 2f;
6.      [SerializeField] private LayerMask jumpableGround;
7.      void Start()
8.      {
9.          rigidbodyComponent = GetComponent<Rigidbody2D>();
10.          groundColl = GetComponent<BoxCollider2D>();
11.      }
12.      void Update()
13.      {
14.          if (Input.GetKeyDown(KeyCode.Space) && IsGrounded)
15.          {
16.              jumpKeyWasPressed = true;
17.          }  
18.      }
19.      private void FixedUpdate()
20.      {
21.          if (jumpKeyWasPressed)
22.          {
23.              rigidbodyComponent.AddForce(Vector2.up * jumpHeight, ForceMode2D.Impulse);
24.              jumpKeyWasPressed = false;
25.          }
26.      }
27.      private bool IsGrounded()
28.      {
29.          return Physics2D.BoxCast(groundColl.bounds.center, groundColl.bounds.size, 0f, Vector2.down, .1f, jumpableGround);
30.      }

My error explains that "Operator '&&' cannot be applied to operands of type 'bool' and 'method group'" but I thought my IsGrounded function returns a bool. I'm still relatively new to coding and I'm unsure how exactly something like this can be converted correctly. Any help is appreciated!

 

IsGrounded() is a Function so

Code (CSharp):

1. if (Input.GetKeyDown(KeyCode.Space) && IsGrounded())

 

Glad this was really simple lol
Thank you!
