Передвижение игрока

Пишу 2d top down шутер на Unity 2017.1 C#. 2 дня как пытаюсь реализовать движение игрока по курсору. Вот мой код:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playerMove : MonoBehaviour {
    void FixedUpdate () {
        GetComponent<Rigidbody2D>().AddForce(Input.GetAxis("Horizontal"));
        GetComponent<Rigidbody2D>().AddForce(Input.GetAxis("Vertical"));
    }
}

Этот код выводит ошибки..

Assets/Scripts/playerMove.cs(8,31): error CS1502: The best overloaded method match for `UnityEngine.Rigidbody2D.AddForce(UnityEngine.Vector2)' has some invalid arguments
Assets/Scripts/playerMove.cs(8,46): error CS1503: Argument `#1' cannot convert `float' expression to type `UnityEngine.Vector2'
Assets/Scripts/playerMove.cs(9,31): error CS1502: The best overloaded method match for `UnityEngine.Rigidbody2D.AddForce(UnityEngine.Vector2)' has some invalid arguments
Assets/Scripts/playerMove.cs(9,46): error CS1503: Argument `#1' cannot convert `float' expression to type `UnityEngine.Vector2'

Что делать?
