Rigidbody.addforce not working,i cannot get my AddForce function to work. it reads the input but will not make the player move. the player has a rgidbody on components as well.

My player character has a rigidbody but the addforce function is not making the character move. ive tried putting it in the FixedUpdate and the normal Update. public class PlayerMovement : MonoBehaviour { public float moveSpeed; private float maxSpeed = 6; private Vector3 input; void Start() { } void FixedUpdate() { if(GetComponent().velocity.magnitude < maxSpeed) input = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical")); GetComponent().AddRelativeForce(input * moveSpeed); } } ,
