    Unhappy Game Starter? (Now with Tic-Tac-Toe!)

    I have been at C++ for quite some time now, but how would I make a game?!

    I use Dev-C++ and everytime I even run the sample New Project -> WINDOWS APP it CANT RUN THE PROGRAM!

    The tutorials I have found just explain arrays text excetera... How would I draw a image? A line?

    Sorry Im a n00b but I am lost how people make there C++ progs.

    Its not a simple matter as youve probably guessed by now nothing is simple in C++ lol. If you don't know how to create windows then I recommend the book Tricks of the Windows Game Programming Gurus. This book assumes you know C++ and starts off nice and gentley with creating windwos and moves onto to cover all about direct x and at the end of it you should know enough to create your games.

    Before worrying about your game, you'll need to find out why you can't compile/run a sample program. What errors are you getting?

    I would suggest starting with console games before you move on to windows. A good first game to program is simple tic tac toe. From there, you can add some AI to your ttt game, or you can move on to something like pong or tetris or maybe checkers. Look into the SDL and Allegro libraries for an easy way to do graphics in console mode.
    Away.

    Smile ok, thanks.

    please keep the comments comming! I will go make a tic-tac-toe soon enough with AI!
    However I have downloaded Allegro expecting different from what I got. It was a bunch of .dat and .txt files in folders. There was nothing I knew how to do.
    I do know that Icy Tower used Allegro however and I love that game...

    you sound an intelligent person, just researc the following winapi calls (well the basic structure and windows based variables would help you also (inparticularly Window Procedures and Window Classes)

    CreateWindow(*);
    BitBlt(*);
    CreateCompatibleDC(*);
    CreateCompatibleBitmap(*);
    SelectObject(*);
    LoadImage(*);
    DeleteDC(*);
    DeleteObject(*);

    Most of these are GDI calls.. and a few User32's, i would totaly research the winapi its so simple and well these days im beginning to think that windows will be the only os avaliable soon (altho mac and linux could pull together and create computers with a nice open source os with really cool mac hardware lol)
    if u want il gladly write a demonstration app (would be in m$ c++ syntax tho) hope it helps

    Smile Thank you all!

    Wow, thanks a lot guys. And I will look into those calls after my tic-tac-toe game. However, I ran into a bug.


    #include <iostream>
    #include <stdlib.h>

    using namespace std; // Whatever the hell that means.

    int main(int argc, char *argv[]) // It was like this when I started. Dont touch!
    {
    // INT the position variables :-p
    int L1_R1 = 0;
    int L1_R2 = 0;
    int L1_R3 = 0;
    int L2_R1 = 0;
    int L2_R2 = 0;
    int L2_R3 = 0;
    int L3_R1 = 0;
    int L3_R2 = 0;
    int L3_R3 = 0;
    int US_ER = 0;
    int CO_NM = 0; /* max = 5 */

    // Intro the user... till they fall asleep... *yahn*
    cout<<"-=[ TIC-TAC-TOE ]=-"<<endl;
    cout<<"-By Cameron Garvie-"<<endl<<endl;
    cout<<"I assume you know how to play Tic-Tac-Toe, and this is no different."<<endl;
    cout<<"I show you the board, and ask for your position. Then I update it."<<endl;
    cout<<"The first player to get three in a row wins. Although I am unbeatable."<<endl;
    cout<<endl<<"The main format for your position is the width then the height.";

    cout<<endl<<"Zero's mean that the space is empty and you may go there.";
    cout<<endl<<endl;

    // You mean we actually "play" the game? lol.
    cout<<"Let's begin! Here is the board:"<<endl;
    while (CO_NM<5)
    {
    // What a ghetto looking board.
    cout<<" "<<L1_R1<<"|"<<L2_R1<<"|"<<L3_R1<<endl;
    cout<<" "<<"- - -"<<endl;
    cout<<" "<<L1_R2<<"|"<<L2_R2<<"|"<<L3_R2<<endl;

    cout<<" "<<L1_R3<<"|"<<L2_R3<<"|"<<L3_R3<<endl;
    cout<<"So what is your choice? ";
    cin>>US_ER;

    // What the hell did they say? And what does it mean?
    if (US_ER = 11) { L1_R1 = 8; } else { L1_R1 = 4; }
    if (US_ER = 12) { L1_R2 = 8; } else { L1_R2 = 4; }
    if (US_ER = 13) { L1_R3 = 8; } else { L1_R3 = 4; }
    if (US_ER = 21) { L2_R1 = 8; } else { L2_R1 = 4; }
    if (US_ER = 22) { L2_R2 = 8; } else { L2_R2 = 4; }
    if (US_ER = 23) { L2_R3 = 8; } else { L2_R3 = 4; }
    if (US_ER = 31) { L3_R1 = 8; } else { L3_R1 = 4; }
    if (US_ER = 32) { L3_R2 = 8; } else { L3_R2 = 4; }
    if (US_ER = 33) { L3_R3 = 8; } else { L3_R3 = 4; }

    CO_NM++;
    }
    return 0;
    }


    The problem is all input fills the chart with 8's. Which is not what I want. When I tried case statements it did not work either. I tried to do this without any tutorials and this was what I got. About me being intelligent - I'll have to work on that, I'm only 10. lol.

    Again, thank you... Now to the debugging! lol.

    PS: About your OS prediction. I agree, but Mac looks soooo much cooler these days. And I just saw some Add about a new G5 Proccessor, the fastest ever! Windows is ahead simply because they have more software, although people illegaly port most to Linux.

    Code:
    if (US_ER = 11) { L1_R1 = 8; } else { L1_R1 = 4; }
    that checks whether US_ER gets set to 11
    Code:
    if (US_ER == 11) { L1_R1 = 8; } else { L1_R1 = 4; }

    By the way, judging by your comments you're confused about a couple of things.

    You should have a look around for some info on the C++ feature "namespaces", don't concern yourself too much with this at the moment as it's a more advanced feature. You just need to know that things like iostream are in the std namespace. So when you say "using namespace std;" you're telling the compiler that you will be saying things like "cout" in your code, and you will be referring to the "cout" in iostream.

    Also, the arguments in the main() function are for command line arguments, which your program can use for various things, like decide how to execute.

    More specifically, argc is the number of arguments and argv is an array of strings, so you could run your program from a command prompt or something like:
    Code:
    c:\myprog.exe argument
    and you could find that the user entered "argument" when he ran the program

    The way it is you can select slot "11" and put an 8 there and then select it your next turn and you put an 8 there again...you could put the values in an array or something and then check each element in the array to see if it is a 4 or an 8 or if they are actually allowed to select that slot

    Unhappy good point...

    Well. I really dont want to continue such a simple game - so I will move on to RPG. But thank you.
