Input axis horizontal is not setup ошибка как исправить

using UnityEngine;
using System.Collections;

public class PlayerMovement : MonoBehaviour {

    private Animator playerAnimator;
    private float moveHorizontal;
    private float moveVertical;
    private Vector3 movement;

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

    // Update is called once per frame
    void Update () {
        moveHorizontal = Input.GetAxisRaw ("Horizontal");
        moveVertical = Input.GetAxisRaw ("Vertical");

        movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
    }

    void FixedUpdate () {
        if (movement != Vector3.zero) {
            playerAnimator.SetFloat ("Speed", 3f);
        } else {
            playerAnimator.SetFloat ("Speed", 0f);
        }
    }
}

Hi Arman,
[I’m learning english, my english is not good]
Double click the error and the Mono or Visual Studio editor will open showing you the position with the cursor in where is the error (close to the error). probably it will select the line where is the error.
If it is

          moveHorizontal = Input.GetAxisRaw ("Horizontal");

since moveVertical and Input.GetAxisRaw do not has a red line under it so probably are correct.
There is also a correct line ending (“”); probably “Horizontal” is not declare in the Input system or was change.

So double check the Input setup by selecting in the unity toolbar, Edit -> project Settings -> Input and in the Inspector you will find Axes. Expand the list. Here you find all the inputs Name and in this case must be Horizontal (is upper case sensitive).

Sometimes this settings can change when you import assets that change them. More in detail the file containing this list is in the folder “ProjectSettings”. There is the file InputManager.asset . If you change this file, it will change all the input settings. When you import an asset that change the files in “ProjectSettings”, unity will let you know.

Hope this answer is close to your question. If is not, look if the ‘Animator’ is attached to the game object.
