Cannot convert void to float.(27, 17): error CS0029

public class PlayerController : MonoBehaviour {

    public float PlayerSpeed;
    public float PlayerJumpHeight;

    private float rotation;

    public int PlayerHealth;

    public bool IsFalling = true;

    private Rigidbody rb;

    // Use this for initialization
    void Start ()
    {
        rb = GetComponent<Rigidbody> ();
    }

    // Update is called once per frame
    void Update ()
    {
        rotation = rb.AddForce (new Vector3(Input.GetAxis("Horizontal"),0,0) * PlayerSpeed);
        rotation *= Time.deltaTime;
        rb.AddRelativeTorque (Vector3.back * rotation);

        if (Input.GetKeyDown(KeyCode.UpArrow) && IsFalling == false)
        {
            rb.velocity = new Vector3 (0, PlayerJumpHeight, 0);
        }
    }

When you are calling rb.AddForce, what are you expecting to be returned? That method call doesn’t return anything, it just does what you tell it (adds a force).

ok, I realized my mistake. Thanks for your help!
