trouble in moving ball and bar at same time (brick game)

[vehshiCoder]

Hi
i am making a simple brick game using win32 console application. I am facing trouble in moving ball and paddle at same time. In the game ball is need to be moved every time. So function which moves the ball need to be called every time.
please suggest me something. Here is my code

#include "stdafx.h"
#include <iostream>
#include <Windows.h>
#include <conio.h>
using namespace std;

HANDLE con=GetStdHandle(STD_OUTPUT_HANDLE);
const int delay = 15000000;

void gotoxy(int x,int y)
{
	COORD Coord;
	Coord.X=x;
	Coord.Y=y;

	SetConsoleCursorPosition(con,Coord);
}

void hide_cursur(void)
{
	HANDLE hConsoleOutput;
	CONSOLE_CURSOR_INFO structCursorInfo;
	hConsoleOutput = GetStdHandle( STD_OUTPUT_HANDLE );
	GetConsoleCursorInfo( hConsoleOutput, &structCursorInfo );
	structCursorInfo.bVisible = FALSE;
	SetConsoleCursorInfo( hConsoleOutput, &structCursorInfo );
}

class BRICK
{
private:
	char  brick_element;
	int xPos;
	int yPos;

public:
	BRICK(void) {brick_element = '@';}
	void setPos(int x, int y) {xPos = x; yPos = y;}
	void print(void) {gotoxy(xPos,yPos); cout << brick_element;}
};

class BAR
{
private:
	char bar_element[5];
	int xPos;
	const int yPos;

public:
	BAR(void):yPos(24) {for(int i = 0; i < 5; i ++) bar_element[i] = '=' ; xPos = 36;}
	void setPos(int x) {xPos = x;}
	void print(void) {gotoxy(xPos,yPos); for(int i = 0; i < 5; i++) cout << bar_element[i];}
	int getX(void) { return xPos;}
};

class BALL
{
private:
	char ball_element;
	int xPos;
	int yPos;

public:
	BALL(void){ball_element = '*'; xPos = 38; yPos = 23;}
	void setPos(int x, int y) {xPos = x; yPos = y;}
	void print(void) {gotoxy(xPos,yPos); cout << ball_element;}
};

class LEVEL
{
private:
	BALL ball;
	BAR bar;
	BRICK bricks[2][20];

	//ball movements
	void move_upright(int& x, int& y)
	{
		for(;;)
		{
			ball.setPos(x,y);
			ball.print();
			for(int i = 0; i < delay; i++);
			gotoxy(x,y); cout << " ";
			x++; y--;

			char input;
			if(kbhit())
			{
				input = getch();
				if(input == 'a') move_bar(1);
				if(input == 's') move_bar(2);
			}

			if(y == 1)   move_downright(x,y);
			if(x == 77) move_upleft(x,y);
		}
	}
	void move_downright(int& x, int& y)
	{
		for(;;)
		{
			ball.setPos(x,y);
			ball.print();
			for(int i = 0; i < delay; i++);
			gotoxy(x,y); cout << " ";
			x++; y++;

			char input;
			if(kbhit())
			{
				input = getch();
				if(input == 'a') move_bar(1);
				if(input == 's') move_bar(2);
			}

			if(x == 77) move_downleft(x,y);
			if(y == 23) move_upright(x,y);
		}
	}
	void move_downleft(int& x, int& y)
	{
		for(;;)
		{
			ball.setPos(x,y);
			ball.print();
			for(int i = 0; i < delay; i++);
			gotoxy(x,y); cout << " ";
			x--; y++;
			
			char input;
			if(kbhit())
			{
				input = getch();
				if(input == 'a') move_bar(1);
				if(input == 's') move_bar(2);
			}
			
			if(x == 1) move_downright(x,y);
			if(y == 23) move_upleft(x,y);
		}
	}
	void move_upleft(int& x, int& y)
	{
		for(;;)
		{
			ball.setPos(x,y);
			ball.print();
			for(int i = 0; i < delay; i++);
			gotoxy(x,y); cout << " ";
			x--; y--;

			char input;
			if(kbhit())
			{
				input = getch();
				if(input == 'a') move_bar(1);
				if(input == 's') move_bar(2);
			}

			if(y == 1) move_downleft(x,y);
			if(x == 1) move_upright(x,y);
		}
	}

	//cursur movemnt
	void move_bar(int a)
	{
		if(a == 1)
		{
			int x = bar.getX();
			bar.setPos(x++);
			bar.print();
		}

		if(a == 2)
		{
			int x = bar.getX();
			bar.setPos(x--);
			bar.print();
		}
	}

public:
	LEVEL(void)
	{
		bar.print();
		ball.print();

		int x = 22;int y = 5;
		for(int i = 0; i < 2; i++)
		{

			for(int j = 0; j < 20; j++)
			{
				bricks[i][j].setPos(x, y);
				bricks[i][j].print();
				x += 2;
			}
			x = 22;
			y++;
		}
	}
	void run(void)
	{	
		int x = 38, y = 23;
		move_upright(x,y);
	}
};


int _tmain(int argc, _TCHAR* argv[])
{
	hide_cursur();
	LEVEL level1;
	level1.run();

	_getch();
	return 0;
}

It is not complete but i think the trouble i am in is major one relativly.
further correct me if i am doing anything which is not a good practice or against OOP.
and if someone suggest a different way to do it, will appreciated.
-regards

I don't know how to use them, but don't you need to use threads to be able to have the program do two separate things at the same time?

Check this out:

#include <windows.h>
#include <stdio.h>
#include <conio.h>

void gotoxy(int x, int y)
{
    COORD pos = { x, y };

    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

struct Object
{
    const char sprite;

    int  x,  y;
    int dx, dy;

    Object(char sprite_, int x_ = 0, int y_ = 0, int dx_ = 0, int dy_ = 0):
        sprite(sprite_), x(x_), y(y_), dx(dx_), dy(dy_) {}

    void UpdateAndDraw()
    {
        gotoxy(x, y);
        printf(" ");

        x += dx;
        y += dy;

        gotoxy(x, y);
        printf("%c", sprite);
    }
};

int main()
{
    Object ball ('*', 10, 10, 1, 1);
    Object bar  ('=', 40, 15);

    const int delay = 25;

    int ball_timer = 0;
    int bar_timer  = 0;

    char input;

    while (true)
    {
        // hit esc to quit
        if (GetAsyncKeyState(VK_ESCAPE) >> 15) break;

        if (ball_timer > 250)
        {
            if (ball.x == 0 || ball.x == 79) ball.dx *= -1;
            if (ball.y == 0 || ball.y == 24) ball.dy *= -1;

            ball.UpdateAndDraw();

            ball_timer = 0;
        }

        if (bar_timer > 50)
        {
            if (_kbhit())
            {
                input = _getch();

                switch (input)

                    case 's': if (bar.y < 24) bar.dy =  1; break;
                    case 'd': if (bar.x < 79) bar.dx =  1; break;
                }
            }

            bar.UpdateAndDraw();

            bar.dx = 0;
            bar.dy = 0;

            bar_timer = 0;
        }

        ball_timer += delay;
        bar_timer += delay;

        Sleep(delay);
    }

    return 0;
}
