I want to put those two condition together but as you see I can't.
Are there anyway to do that?
Help me pls.

What I have tried:

void Jump()

      if (Input.GetButtonDown("Jump") && isGrounded )
          gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0f, 5f),

Since Unity - Scripting API: Input.GetButtonDown[^] returns a bool, I'd look at the definition of isGrounded - the error says it's a method, not a bool property or field. If so, it needs "()" to call it.
