Well the problem is: I have been following the Hack and Slash Tutorial, i'm at Health Bar 2/2, but there is a problem with my Scrip, get the following errors:

Error 1 Only assignment, call, increment, decrement, and new object expressions can be used as a statement C:\Users\Zelda-Maniack\videogame\game1\OrbS\Assets\Scripts\PlayerHealth.cs 31 21 OrbS

Error 2 ; expected C:\Users\Zelda-Maniack\videogame\game1\OrbS\Assets\Scripts\PlayerHealth.cs 31 21 OrbS

Both of them are in the same line and in the adj statement:

curHealth ++ adj;

Here is the script, When i delete that line all the errors disappear. 

using UnityEngine;
using System.Collections;

public class PlayerHealth : MonoBehaviour 
{
    public int maxHealth = 100;
    public int curHealth = 100;

    public float healthBarLenght;

    // Use this for initialization
    void Start () 
    {
        healthBarLenght = Screen.width / 2;
    }

    //Update is called once per frame
    void Update() 
    {
        AddJustCurrentHealth(0);

    }

    void OnGUI()
    {
        GUI.Box(new Rect(10, 10, healthBarLenght, 20), curHealth + "/" + maxHealth);
    }

    public void AddJustCurrentHealth(int adj)
    {
       curHealth ++ adj;
        healthBarLenght = (Screen.width / 2) * (curHealth /(float)maxHealth);

    }

Please help me I'm getting a little desperate XD.

Looking at this line of code:

curHealth ++ adj;

I believe you want to add the value of `adj` to the value of `curHealth`, and store it back into `curHealth`. For C-derivative code, use +=.

i.e.

curHealth += adj;
