make player move in direction it's facing

Question

Hello to all, currently I am having issues making my player move in the direction of its rotation. For some reason it only wants to move in the first direction it was facing. I would like it to continue to only move by hoping. Thanks in advance!

 public GameObject player;
 public float speed = 7.0f;
 public float rotateSpeed = 3.0f;
 

 void Update()
 {     
     //Moves player upwards
     if (Input.GetAxis("Vertical") == 1)
     {
         var move = new Vector3(0, Input.GetAxis("Vertical"), 0);
         transform.Translate(transform.up * speed * Time.smoothDeltaTime);
     }

     //Rotates player direction
     if (Input.GetAxis("HorizontalTurn") > 0)
         transform.Rotate(Vector3.up * 90 * Time.deltaTime);

     else if (Input.GetAxis("HorizontalTurn") < 0)
         transform.Rotate(Vector3.up * -90 * Time.deltaTime);

     //launches player forward based on momentum from left stick and facing direction of right
     if (Input.GetAxis("rightTrigger") == 1 && Input.GetAxis("Vertical") == 1)
          {
               transform.position += Vector3.forward * Time.deltaTime * speed;
          }
 }

}

Use Rigidbody to make it easy:

 public float movementSpeed = 10f;
 Vector3 movement;
 
 Rigidbody rigidbody;
 
 void Awake()
 {
     rigidbody = GetComponent<Rigidbody>();
 }
 
 void FixedUpdate()
 {
     float horizontal = Input.GetAxisRaw("Horizontal");
     float vertical = Input.GetAxisRaw("Horizontal");
 
     MoveCharacter(horizontal, vertical);
 }
 
 void MoveCharacter(horizontal, vertical)
 {
     movement.Set(horizontal, 0, vertical);
     if (horizontal != 0 || vertical != 0)
     {
         rigidbody.MoveRotation(Quaternion.LookRotation(movement));
     }
     movement = movement.normalized * movementSpeed * Time.deltaTime;
     rigidbody.MovePosition(transform.position + movement)
 }

That's the code if I remember it right. Haha

You should move your player with a Rigidbody.
transform.Translate is more like teleportation and doesn't always collide correctly with objects.
To move your player according to its rotation, use the Rigidbody.AddRelativeForce method.
