вот мой код:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerController : MonoBehaviour
{
    public float speed;
    public float jumpForce;
    private float moveImput;
    private Rigidbody2D rb;
    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }
    private void FixetUbdate()
    {
        moveImput = moveImput.GetAxis("Horizontal"); 
        rb.velocity = new Vector2(moveImput * speed, rb.velocity.y);
    }
}
вот ошибка: 
Assets\PlayerController.cs(20,31): error CS1061: 'float' does not contain a definition for 'GetAxis' and no accessible extension method 'GetAxis' accepting a first argument of type 'float' could be found (are you missing a using directive or an assembly reference?)
