Чтобы заставить вашего игрока двигаться в направлении вашего вращения в Unity, вы можете использовать различные методы. Вот несколько примеров:

Метод 1: использование Transform.forward

public class PlayerController : MonoBehaviour
{
    public float speed = 5f;
    private Rigidbody rb;
    private void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    private void Update()
    {
        // Get the rotation of the player
        Quaternion rotation = transform.rotation;
        // Get the forward direction based on the rotation
        Vector3 direction = rotation * Vector3.forward;
        // Normalize the direction to maintain consistent speed
        direction.Normalize();
        // Apply movement to the player
        rb.MovePosition(transform.position + direction * speed * Time.deltaTime);
    }
}

Метод 2: использование углов Эйлера

public class PlayerController : MonoBehaviour
{
    public float speed = 5f;
    private Rigidbody rb;
    private void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    private void Update()
    {
        // Get the rotation of the player in Euler angles
        Vector3 rotation = transform.eulerAngles;
        // Calculate the forward direction based on the rotation
        Vector3 direction = Quaternion.Euler(rotation) * Vector3.forward;
        // Normalize the direction to maintain consistent speed
        direction.Normalize();
        // Apply movement to the player
        rb.MovePosition(transform.position + direction * speed * Time.deltaTime);
    }
}

Метод 3: использование Transform.rotation и Transform.TransformDirection

public class PlayerController : MonoBehaviour
{
    public float speed = 5f;
    private Rigidbody rb;
    private void Start()
    {
        rb = GetComponent<Rigidbody>();
    }
    private void Update()
    {
        // Get the rotation of the player
        Quaternion rotation = transform.rotation;
        // Get the forward direction based on the rotation
        Vector3 direction = rotation * Vector3.forward;
        // Transform the direction from local space to world space
        direction = transform.TransformDirection(direction);
        // Normalize the direction to maintain consistent speed
        direction.Normalize();
        // Apply movement to the player
        rb.MovePosition(transform.position + direction * speed * Time.deltaTime);
    }
}
