Hi community, this is my first ever post, I read the guidelines so I searched as much as I could in the forums for this topic and couldn't find a post similar. So I am currently programming this island maze using two-dimensional arrays in C#. The purpose of the program is to ask the user for the size of the island (x rows, y columns) and then have a drunk guy placed near the center of the maze. Using Random method, 1-4, if 1 then the drunk guy moves up if 2 he moves left and etc... Using (+'s) char to represent the land, and (W's) to represent the water, and (B's) to represent the random placement of bridges where he will survive if he makes it to them. So far I have everything working properly except the placement of the drunk islander.

I've been using x/2, y/2 to have the (D) or drunkin guy placed in the center of the matrices or island. When I try to have my MoveDrunk method move drunk[x, y] up, left, down, right, I have no variable to associate with that random placement of the drunk guy coordinate or index. All I have found was the IndexOf() and BinarySearch() System.Array methods. But those are only one dimensional methods. I then found out there's no way to evaluate a two dimensional index? Supposedly I must now create my own algorithm to calculate that drunk guys location so I could move him (some variable)+1 right (some variable)-1 left etc...

Any ideas on how I could create this for my game or even another approach I could take?

Here's what's in my main method so you get a better idea.

Thanks,

Dustin

Console.WriteLine("All you need to know... \n1 moves drunk up, 2 moves drunk right, 3 moves drunk down, 4 moves drunk left");

Console.WriteLine("Please enter the amount of rows you want for your island, \nmust be greater than 3.");

string input = Console.ReadLine();

int rows = int.Parse(input);

Console.WriteLine("Please enter the amount of columns you want for your island, \nmust be greater than 3.");

input = Console.ReadLine();

int columns = int.Parse(input);

int exaustion = 0;

//Console.WriteLine("\nPlease enter the number of bridges you prefer.");

//string bridgeInput = Console.ReadLine();

//int bridgeCount = int.Parse(bridgeInput);

char[,] island = Dimensions(rows, columns);

Water(island, rows, columns);

Bridge(island, rows, columns);

//, bridgeCount

Land(island, rows, columns);

//InitDrunk(island, rows, columns); //Not using currently

//PlaceDrunk(island, rows, columns); //Not using currently

island[rows / 2, columns / 2] = 'D'; //Heres where I get my center placement of my drunk before passing into MoveDrunk()

MoveDrunk(island, rows, columns, exhaustion); //<-- Heres where I got to find a way to get that index

Island(island, rows, columns);

Console.Read();

Okay, well I thought that's what I needed to get this to work but sadly my drunk guy keeps making two turns, and my bridges on the right wont appear, and my end game method is dysfunctional? I tried the approach for adding another class but with the current state of my code I feel like its to difficult to rearrange everything. I did mange to make some progress but once I added my lives, drowns, and starves my code became inoperable. Here's what I have for anyone willing to give more suggestions.

I am pleased to note that I got full functionality to my program!!

Besides my exhaustion doesn't update for some reason and my starves doesn't increment. Thanks for the help BearNutts for pointing my obvious mistakes.
