i need the snake not to pass by the walls...can anyone help me?
here is the progam.cs
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
namespace TikTak
{
class TestCon
{
[DllImport("msvcrt")]
static extern int _getch();
static void Main()
{
ConsoleHelper ch = new ConsoleHelper();
char move;
short x = 1, y = 1;
string[,] maze = new string[15, 15];
short a, b;
for (a = 0; a <= 14; a++)
{
for (b = 0; b <= 14; b++)
{
maze[a, b] = "x";
Console.Write("{0}", maze[a, b]);
}
Console.Write("\n");
}
for (a = 1; a < 14; a++)
{
for (b = 1; b < 14; b++)
{
if (a == 1 || a == 3 || a == 5 || a == 7 || a == 9 || a == 11 || a == 13 || (a == 2 && b == 13)
|| (a == 4 && b == 1) || (a == 6 && b == 13) || (a == 8 && b == 1) ||

{
ch.gotoxy(b, a);
maze[a, b] = "+";
Console.Write("{0}", maze[a, b]);
}
}
Console.Write("\n");
}
Console.Write("\n\nNOTE: Use your arrow keys to move");
do
{
move = (char)_getch();
if (move == 80 && y >= 1 && y <= 40)
{
ch.gotoxy(x, (short)(y + 1));
Console.Write(".\b");
y++;
}
else if (move == 72 && y > 1 && y <= 41)
{
ch.gotoxy(x, (short)(y - 1));
Console.Write(".\b");
y--;
}
else if (move == 77 && x >= 1 && x <= 60)
{
ch.gotoxy((short)(x + 1), y);
Console.Write(".\b");
x++;
}
else if (move == 75 && x > 1 && x <= 61)
