Total noob here. This is my first c# attempt, its a console application that simulates a drinking game called 'Left Right Center'. In the console I receive the following:
CONSOLE
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
at LeftRightCenter.MainClass.Main (System.String[] args) [0x00038] in /Users/apple/Projects/LearningC/LearningC/Main.cs:80
[ERROR] FATAL UNHANDLED EXCEPTION: System.NullReferenceException: Object reference not set to an instance of an object

C#
using System;
namespace LeftRightCenter
{
class Player
{
//fields
private int _quarters = 4;
public int Quarters {
get{ return _quarters; }
set{ _quarters += value; }
}
public Player (string name)
{
}
}
class Dice
{
Random random = new Random();
public int Roll ()
{
random = new Random ();
int diceSide;
diceSide = random.Next (0, 6);
diceSide = (diceSide > 2) ? 3 : diceSide;
return diceSide;
}
}
class MainClass
{
static int activePlayer = 0;
static int theCup = 0;
static Player[] thePlayers = {
new Player ("Jessica"),
new Player ("Isaac"),
new Player ("Ed"),
new Player ("Bella"),
new Player ("Elisa"),
new Player ("Fake RedHead"),
new Player ("Linda"),
new Player ("MJ"),
new Player ("Irene"),
new Player("Devin")
};
static Dice[] theDice = new Dice[2];
private static void MoveQuarter (int direction)
{
int numberOfPlayers = thePlayers.Length - 1;
switch (direction) {
case 0:
thePlayers [activePlayer].Quarters = -1;
theCup++;
break;
case 1:
thePlayers [activePlayer].Quarters = -1;
int leftPlayer = (activePlayer == 0) ? numberOfPlayers : activePlayer - 1;
thePlayers [leftPlayer].Quarters = +1;
break;
case 2:
thePlayers [activePlayer].Quarters = -1;
int rightPlayer = (activePlayer == numberOfPlayers) ? 0 : activePlayer + 1;
thePlayers [rightPlayer].Quarters = +1;
break;
}
}
public static void Main (string[] args)
{
int cupEndPoint = thePlayers.Length * 4 - 1;
while (theCup < cupEndPoint) {
foreach (Dice rattle in theDice) {
if (thePlayers [activePlayer].Quarters > 0) {
MoveQuarter (rattle.Roll ()); // this line seems to be the problem
}
}
Console.WriteLine ("{0} Quarters In the Cup", theCup);
}
}
}
}
I have no idea what the problem is or why, and my googling have proven more use confusing than helpful.
