Hai
I have one doubt when end your game program i.e. (run program
continuously till user press escape)
Ok I give some suggestion
1)Increase snack length when eat food
2)Add score(based on maximum food eat with in a time ) to
your program and print to user
Any way
I made small changes in your program see the following
code .Now it will run as per your desire(now it show one food at a
time ), I add comment line in your program where I made change and I
remove some unwanted statements.
using System;
namespace SnakeConsoleApplication
{
class Program
{
static void ShiftLeftArrays(short[] xSnake, short[] ySnake)
{
for (int i = 0; i < xSnake.Length - 1; i++)
{
xSnake[i] = xSnake[i + 1];
ySnake[i] = ySnake[i + 1];
}
}
static void OpositeArray(short[] a)
{
int upIndex = a.Length - 1, lowIndex = 0;
short temp;
for (int i = 0; upIndex > lowIndex; i++)
{
temp = a[upIndex];
a[upIndex] = a[lowIndex];
a[lowIndex] = temp;
upIndex--;
lowIndex++;
}
}
static void ShowFirstSnake(short[] xSnake, short[] ySnake)
{
for (int i = 0; i < xSnake.Length; i++)
{
Console.SetCursorPosition(xSnake[i], ySnake[i]);
Console.Write("*");
}
}
static void Main(string[] args)
{
const short WINDOW_WIDTH = 80;
const short WINDOW_HEIGHT = 49;
short potx=0, poty=0;
short[] xSnake = { WINDOW_WIDTH / 2, WINDOW_WIDTH / 2 +
1,WINDOW_WIDTH / 2 + 2, WINDOW_WIDTH / 2 + 3, WINDOW_WIDTH / 2 + 4 };
short[] ySnake = { WINDOW_HEIGHT / 2, WINDOW_HEIGHT / 2,
WINDOW_HEIGHT / 2, WINDOW_HEIGHT / 2, WINDOW_HEIGHT / 2 };
Console.CursorVisible = false;
Console.BackgroundColor = ConsoleColor.Blue;
Console.Clear();
Console.ForegroundColor = ConsoleColor.Yellow;
Console.WindowHeight = WINDOW_HEIGHT;
Console.WindowWidth = WINDOW_WIDTH;
ShowFirstSnake(xSnake, ySnake);
//show first food
ShowFood( ref potx,ref poty);
ConsoleKeyInfo KeyIn, lastKey;
KeyIn = Console.ReadKey(true);
lastKey = KeyIn;
while (KeyIn.Key != ConsoleKey.Escape)
{
if (KeyIn.Key == ConsoleKey.RightArrow)
{
if (lastKey.Key == ConsoleKey.LeftArrow)
{
OpositeArray(xSnake);
OpositeArray(ySnake);
}
Console.SetCursorPosition(xSnake[0], ySnake[0]);
Console.Write(" ");
ShiftLeftArrays(xSnake, ySnake);
xSnake[xSnake.Length - 1]++;
}
if (KeyIn.Key == ConsoleKey.UpArrow)
{
if (lastKey.Key == ConsoleKey.DownArrow)
{
OpositeArray(xSnake);
OpositeArray(ySnake);
}
Console.SetCursorPosition(xSnake[0], ySnake[0]);
Console.Write(" ");
ShiftLeftArrays(xSnake, ySnake);
ySnake[xSnake.Length - 1]--;
}
if (KeyIn.Key == ConsoleKey.LeftArrow)
{
if (lastKey.Key == ConsoleKey.RightArrow)
{
OpositeArray(xSnake);
OpositeArray(ySnake);
}
Console.SetCursorPosition(xSnake[0], ySnake[0]);
Console.Write(" ");
ShiftLeftArrays(xSnake, ySnake);
xSnake[xSnake.Length - 1]--;
}
if (KeyIn.Key == ConsoleKey.DownArrow)
{
if (lastKey.Key == ConsoleKey.UpArrow)
{
OpositeArray(xSnake);
OpositeArray(ySnake);
}
Console.SetCursorPosition(xSnake[0], ySnake[0]);
Console.Write(" ");
ShiftLeftArrays(xSnake, ySnake);
ySnake[xSnake.Length - 1]++;
}
Console.SetCursorPosition(xSnake[xSnake.Length - 1],
ySnake[ySnake.Length - 1]);
Console.Write("*");
lastKey = KeyIn;
KeyIn = Console.ReadKey(true);
if (xSnake[0] == potx && ySnake[0] == poty)
//when user can reached next food will appear
ShowFood(ref potx, ref poty);
}
Console.WriteLine();
}
//your Point function replaced with following function
static void ShowFood( ref short potx,ref short poty)
{
Random rnd = new Random();
potx = (short) rnd.Next(50);
poty = (short) rnd.Next(50);
Console.SetCursorPosition(potx, poty);
Console.Write("*");
}
}
}
I hope this code will satisfy you
