Build error "A new Expression requires() or [] after type"

Question

I’m creating a video game based on a youtube... And in this video there is a link to the site with the codes, I copied the codes and pasted it exactly as it was to later modify and do my way... But there are some mistakes in Unity that I can’t fix!

Error occurs in class code Dinheiro:

using UnityEngine;
using System.Collections;

public class Dinheiro : MonoBehaviour {

public Vector2 velocity = new Vector2(0, -4);
public Vector3 velocity3D = new Vector3(0, -4, 0);
public float range = 4;

// Use this for initialization
void Start () {

    //rigidbody2D.velocity = velocity;
    transform.position = new Vector3(transform.position.x – range * Random.value, transform.position.y , transform.position.z);

}



// Update is called once per frame
void Update () {
    transform.position += velocity3D * Time.deltaTime;
}

}

The error message is A new expression requires () or [] after type and the compiler indicates line 14, where there is the command transform.position = new Vector3(..., as shown below:

After performing some tests, the problem seems to be related to the characters used in the code.

As you said yourself, you copied the code from a web page and pasted it directly into the Unity editor. Once that was done, the text was pasted as formatted on page (that is, using Unicode-encoded characters instead of ANSI). For example, a longer hyphen instead of the subtraction signal is what caused the pointed error in the question.

This type of error is more easily observable in the strings where the pasted code is this (which are other errors that you would get if you fixed this first):

InvokeRepeating(“CreateObstacle”, 1f, 1.5f); // em Generate.cs

instead of being like this (using quotes normal, as typed directly via keyboard):

InvokeRepeating("CreateObstacle", 1f, 1.5f);

This "problem" probably stems from the Unity editor’s feature of pasting formatted text (type RTF). I don’t know if this may or may not be considered a tool bug, but it probably causes these kind of difficulties frequently. :)
