Moving a ball in different directions.

Hello Devs!

I'm kinda new to unity and im really enjoying learning new things.

At the moment im building a platform game, where the player is a sphere shape.

I'm at the point where I can move my player, forward, backwards and sideways.
I did this by adding a force to my rigidbody.

At this point im kinda struggling.
What I want is by pressing a or d, I rotate my ball and then if I press W, I roll in the dirrection the ball is facing.

The first part of the code is a comment, I tried it with my own code and got stuck, tried a new code but simply could not figure out how to get it to work.

At this point the ball is rotating but i cant figure out how to move in the "new" forward direction.

Code (CSharp):

Oke I'm an idiot..

After creating this topic I found out that there is a unity tut for this.

Im sorry, i made it work with this code:

Code (CSharp):

1. public class Speler_Beweging : MonoBehaviour
2. {
3.     public Rigidbody rb;
4.     public float moveSpeed = 10f;
5.     public float turnSpeed = 10f;
6.     void start()
7.     {
8.         rb = GetComponent<Rigidbody>();
9.     }
10.  
11.     private void FixedUpdate()
12.     {
13.         float moveHorizontal = Input.GetAxis("Horizontal");
14.         float moveVertical = Input.GetAxis("Vertical");
15.  
16.         Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
17.  
18.         rb.AddForce(movement * moveSpeed);
19.     }
20. }
