Countdown & timer?

[TrulyRazor]

Hello!

I am currently trying to make a little game.

Basically, it picks a number say between 1 and 10, and you have to guess it.

I want to give the user 3 tries per guess with 5 guesses per round, and I want them to have 20 seconds per guess.

After they fail to get 3 guesses either by taking too long or using all their guesses, I want the game to end and to print a score. (in total seconds lasted)

I also want the game to get progressively harder (using a larger scale like 1-20, 1-30, etc.) and to give them either less guesses/less time to get it (randomly)).

I would like to have a countdown at the start that says "starting in 1... 2... 3... go!" to give them a chance to get ready, and also one between rounds.

I'm not sure how to go about this, so any help will be greatly appreciated!

Thanks!

You can use a sleep function for the timer.

#include <windows.h>
#include <iostream>

int main(void) {
        std::cout<<"This program will waste 15 seconds of time.";
        Sleep(15000);
        std::cout<<std::endl<<"Thanks for letting us waste your time...";
        std::cin.ignore();
}

here is my demo for one round, secret number random from 1 to 10, 5 guesses per round, 20 seconds per guess:

#include <iostream>
#include <string>
#include <windows.h> // GetAsyncKeyState(), Sleep()
#include <conio.h>   // getch()
#include <ctime>     // time()
#include <cstdlib>   // srand(), rand(), atoi()
using namespace std;

int get_int(int sec);

int main()
{
    srand(time(0));
    int comp_num = rand() % 10 + 1;  //random 1-10
    int guess = 0;
    int lives = 5;  //5 guesses
    int guess_time = 20;  //20 secs / guess

    while (guess!=comp_num && lives)
    {
        guess = get_int(guess_time);
        if (guess != comp_num) {
            cout << "Wrong! The number is "
                 << (comp_num>guess ? "higer" : "lower")
                 << " than your guess\n";
            --lives;
        }
    }
    cout << "You " << (guess==comp_num ? "win" : "lose") << "!\n"
         << "The number is " << comp_num << "\n";
    cin.ignore(100,'\n');
}

int get_int(int sec)
{
    static const int sensitivity = 150; //higher == lesser sensitive
    time_t now = time(0);
    string input;
    while (time(0)-now < sec)
    {
        if (GetAsyncKeyState(VK_RETURN)) {  // enter/return 
            getch();
            Sleep(sensitivity);
            break;
        }
        if (GetAsyncKeyState(VK_BACK)) {  // backspace
            getch();
            cout << "\b \b";
            if (!input.empty())
                input.erase(input.end()-1);
        }
        for (int c=0x30; c<=0x39; ++c)  // 0-9, NUMPAD_0-NUMPAD_9
            if (GetAsyncKeyState(c) || GetAsyncKeyState(c+0x30)) {
                input += (char)c;
                cout << (char)c;
                getch();
            }
        //other printable keys...
        if (GetAsyncKeyState(0x20)) getch(); // space
        for (int c=0x41; c<=0x5a; ++c) // A-Z
            if (GetAsyncKeyState(c)) getch();
        for (int c=0x6a; c<=0x6f; ++c) // other NUMPAD keys
            if (GetAsyncKeyState(c)) getch();
        for (int c=0xba; c<=0xc0; ++c) // other US standard keys
            if (GetAsyncKeyState(c)) getch();
        for (int c=0xdb; c<=0xdf; ++c) // other US standard keys
            if (GetAsyncKeyState(c)) getch();
        Sleep(sensitivity);
    }
    cout << "\n";
    return atoi(input.c_str());
}

the hardest part is "to have 20 seconds per guess." I need both windows.h and conio.h (both non-standard) to do this...

Wow, that's awesome. Thanks!

I made a version myself without the timed thing, and I'd really appreciate your feedback!
