In this video (objectives)…

  1. Create a new function for StartGame().
  2. Create a new function for NextGuess().
  3. Discussion encapsulating as it relates to C#.
  4. Finish our game.

After watching (learning outcomes)…

Create your first functions and finish off our simple game.

    private void IntializeStuff()
    {
        max = 1000;
        min = 1;
        guess = Random.Range(min, max);
        PrintWelcome();
        max = max + 1;
    }

    void PrintWelcome()
    {
        Debug.Log("Hi All, time to play number wizard: ");
        Debug.Log("Pick a number: ");
        Debug.Log("The highest number is " + max);
        Debug.Log("The lowest number is " + min);
        Debug.Log("Is it higher or lower than: " + guess);
        Debug.Log("Push Up arrow for Higher, Down Arrow for Lower, and Enter for Correct");
    }
}

My version. Good to have a speed revision of unity. Its been a while

Quick question, hoping someone can shed some light here.

In this part of the code:

void StartGame()
{
max = 1000;
min = 1;
guess = 500;

Why is it that if you declare these local variables as integers again the output of the program is always zero?

I understand there isn’t need to declare them again (as recommended @ 10.41) and it would be cleaner not to do so, however this error stumps me and I’m not sure why it output to always return zero.
