help with my first game please
Hello, Im writing my first ever game in C#. At the moment it takes input from the user and displays the
grid with the correct location of the user input. For some reason it wont allow the computer to input a
random number.
my code is:
using System;
using System.Collections.Generic;
using System.Text;
namespace tictactoe
{
class Program
{
static char[,] matrix = new char[3, 3];
static char done;
//ClearConsole ClearMyConsole = new ClearConsole();
static void Main(string[] args)
{
// ________________MAIN FUNCTION ______________________
screen_one();
Console.Clear();
initialise_matrix();
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Start DO LOOP
do
{
display_matrix();
get_player_move();
check_emptycell();
done = check_emptycell();
if (done == 'd')
{
display_matrix();
break;
}
else
{
check_down();
done = check_down();
}
if (done != ' ')
{
break;
}
else
{
display_matrix();
get_computers_move();
check_down();
done = check_down();
}
if (done !=' '){
break;}
else
{
display_matrix();
//CALL display_matrix function
}
display_matrix();
Console.Clear();
} while (done == ' '); //~~~~~~~~~~END DO LOOP
if (done == 'O'){
display_matrix();
}//END IF
if (done == 'd'){
//IF done = 'd' THEN
Console.WriteLine("Its a draw!!!");
}
else
{
Console.WriteLine("The winner is {0}",done);
//OUTPUT “The winner is {0}",done
//INPUT
Console.ReadLine();
}
}//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ END OF MAIN FUNCTION
static char check_emptycell(){
//FOR i=0 to < 3
for(int i=0;i<3;i++){
if(matrix[i,0] == ' ') {
return ' ';
}
else if (matrix[i,1] ==' '){
return ' ';
}
else if (matrix[i,1] == ' '){
return ' ';
}
//END IF
}
return 'd';
}// end check_emptycell function
static void screen_one(){
string myvalue;
do
{
Console.Clear();
Console.WriteLine("This Os and Xs game You to play the computer");
Console.WriteLine("press a key to start game");
myvalue = Console.ReadLine();
} while (myvalue != "");//END WHILE LOOP myval != ""
}
static void initialise_matrix(){
for (int i=0;i<3;i++){
for (int j = 0; j < 3; j++)
matrix[i, j] =' ';
}
}//end initialise_matrix function
static void display_matrix(){
for (int t = 0; t < 3;t++ ){
Console.WriteLine(" {0} | {1} | {2} ", matrix[t, 0], matrix[t, 1], matrix[t, 2]);
if (t != 2)
Console.WriteLine("\n---|---|---\n");
}
Console.WriteLine("");
}
static void get_player_move(){
int x,y;
Console.WriteLine("Enter row for your X:");
x = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("enter column for your X:");
y = Convert.ToInt32(Console.ReadLine());
x=x-1;
y=y-1;
matrix[x, y] = 'X';
}//end get_player_move function
//start check_down function
static char check_down()
{
//int i=0;
//FOR x=0 to < 3
for(int i=0;i<3;i++)
if (matrix[0,i]==matrix[1,i] & matrix[0,i]==matrix[2,i]){
return matrix[0,i];
}
else if (matrix[i,0]==matrix[i,1] & matrix[i,0]==matrix[i,2]){
return matrix[i,0];
}return ' ';
//ELSEIF matrix[i,0]=matrix[i,1]AND matrix[i,0]=matrix[i,2]THEN
}
//START GET_COMPUTERS_MOVE
static void get_computers_move(){
Random rand = new Random();
int x = rand.Next(4);
int y = rand.Next(4);
for(x=0;x<3;x++){
for(y=0;y<2;y++)
if (matrix[x, y] == ' ')
break;
if (matrix[x, y] == ' ')
break;
if (x * y > 4)
done='d';
else
matrix[x,y] = 'O';
}
}//end get_computers_move function
}
}
