roll a ball Assets/Scripts/PlayerController.cs(17,75): error CS1729: The type `UnityEngine.Vector3' does not contain a constructor that takes `4' arguments

i keep getting this error even though i copied the script exactly from the tutorial

using UnityEngine;
using System.Collections;

public class NewBehaviourScript : MonoBehaviour {
    private Rigidbody rb;
	// Use this for initialization
	void Start () {
        rb = GetComponent<Rigidbody>();
	}
	
	// Update is called once per frame
	void FixedUpdate ()
    {
        float moveHorizontal = Input.GetAxis ("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0,0f, moveVertical);

        rb.AddForce(movement);
	}
}

There’s one argument too much in the constructor of the Vector that you’re trying to create:

Vector3 movement = new Vector3(moveHorizontal, 0,0f, moveVertical);

If you need to write a float value, you need to use a dot ( 0.0f ):

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

But in this case, simply 0f (or 0) will just do as fine as 0.0f

Vector3 movement = new Vector3(moveHorizontal, 0f, moveVertical);
