i want to make a game :) by using c++ but i can't finish it :( because of there are some problem about the code....the aim of the game is to stop the ball from hitting the right wall
by moving the box. 10 pts r given 4 stopping it once. speed adds as the score increases by 100. But it doesn't work and i do not know why.....:-/ :confused: can somebody help me to find the solution of this problem......:?:
this is the code of the game:
#include<iostream>
#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
#include <dos.h>
int midx, midy, x, y, sx, sy, by, scr, spd, ch=3;
int r=20, i, d=0;
/*
midx,midy = mid of screen
x,y = coordinates of ball (initial pos can be changed)
sx,sy = direction for ball to mov (1 for +ve, 0 for -ve)
by = location of box
scr = score
spd = speed
ch = menu choice
r = radius of ball
i = for internel loops
d = debugging mode on / off
*/
void load();
void menu();
void box();
void gamover();
