Moving player between pre-determined points

Hello!

I’m new to unity and have some questions for you guys.

I’m creating a 2d game in which you move a rabbit between 3 lanes in order to avoid falling blocks. I already have a character with animation and collision standing on a sprite with a box collider that acts as ground.

So basically i would like to know how to move my rabbit left and right between 3 points using arrow keys.
I found plenty of tutorials online in how to make a character move around, but nothing regarding this.
Or maybe i just don’t know what to google.

Here’s a picture to further illustrate my problem since my english isn’t the best.

You can do something like this:

public Vector3 leftPos;
public Vector3 rightPos;
public Vector3 centralPos;

void Start()
{
    //Start in the center position
    transform.position = centralPos;
}

void Update()
{
    //move to the correct position
    var posToMove = DeterminePos(transform.position);
    if (posToMove != null)
        transform.position = (Vector3)posToMove;
}

private Vector3? DeterminePos(Vector3 pos)
{
    if (Input.GetKeyDown(KeyCode.LeftArrow))
    {
        //check if we are in the outer left
        if (transform.position == leftPos)
            return leftPos; //return same position because we don't need to move
        if (transform.position == centralPos)
            return leftPos; //we want to move to the outer left position
        if (transform.position == rightPos)
            return centralPos; //we want to move to the center position
    }

    if (Input.GetKeyDown(KeyCode.RightArrow))
    {
        //check if we are in the outer left
        if (transform.position == rightPos)
            return rightPos; //return same position because we don't need to move
        if (transform.position == centralPos)
            return rightPos; //we want to move to the outer right position
        if (transform.position == leftPos)
            return centralPos; //we want to move to the center position
    }
    return null; //default
}
