First Game

[CheesyMoo]

I know you probably all think I'm a dumb n00b, but oh well.
I made my first game(it doesn't really count) it was a mad lib game, it was really easy but, I want to make a game like tic-tac-toe or something... I'm lost I really have no idea on how to start, I've read tutorials and all they say is stuff like you can't start out making quake 3 start small... that really doesn't help, does any body example code for a tic-tac-toe game or other VERY simple game... thanks.

What's mad lib?
Well Tic-Tac-Toe is about the easiest thing i can think of,
imagin an array


int spot[10]; // 10 instead of 9 because 10 doesnt count


you ask the input from a player and proces it


if(key_pressed=="1")
spot[1]==current_player; // current player is an int holding the....


and you print it


cout << spot[1] << spot[2] << spot[3] << endl;
cout << spot[4] << spot[5] << spot[6] << endl;
cout << spot[7] << spot[8] << spot[9] << endl;


That just about covers the basics.

No, you'd still use spot[9]...
0-8 = 9 elements, while 9th holds the NULL terminator.

[CheesyMoo]

Is goto statement for C++ like in BASIC? I'm trying to think of a way to have it ask for the input again and go back to the switch statement without writing it over and over alot.

TicTacToe - you can have a 2d array

char board[3][3];


And then make a function to print the board,
another function to get data and put in the array, another to check if we have a winner and so on...

Not too hard.
Hmm A nice game is: "The Game of the life".
If you wan't some info about him, tell.

[CheesyMoo]

Nevermind, I fixed it.

[CheesyMoo]

I've been workin' for a while and I got it to run and the only problem is, it asks for only player ones input, but I think I can figure it out, I just need a rest thanks for the help! I think in a couple of days I'll have my first working game!

Only strings have a Null terminator, not 'normal' arrays.

....there is....BUT YOU MUST NOT USE IT!!!! NEVER!!!
Use while,do or for loops instead

[CheesyMoo]

I finished it, got out most of the bugs and here it is, I think I can upload it... I don't really know how but give me your thoughts on it and any bugs you find thanks.

[Travis Dane]

I stumbled among some problems:

You're using the old <iostream.h>, The new one is <iostream>

You don't have 'using namespace std' but you don't specify them
with std functions either.

You're using the Boreland clscr(); command, i replacement is '
system("cls");'.

The variable 'uno' doesn't seem to be initilized.

[CheesyMoo]

My compiler won't recognize namespace std... everytme I type it in it says, bad initilazation or something like that...

You changed <iostream.h> to <iostream>?
You must use 'using namespace std'.

[CheesyMoo]

I type in #include <iostream>
using namespace std;

It says, can't find IOSTREAM
Bad syntax,declaration error(for using namespace)

[Travis Dane]

Hm, specify your compiler.

[CheesyMoo]

Borland Tubro C++ 4.5, maybe I don't have a setting turned on or something.

[Travis Dane]

It might be possible you have an old compiler, if so your program
cannot compile without few changes on other newer compilers.
But after changing some things it worked fine.

You should check the if the user input is a number. I typed quit (dunno why I just felt like it) and the program went into an infinite loop telling me choose another number.

Another good alternative i like to do is writing my own CIN,
It really isn't that hard. Sokra how about saying how to filter
out numbers? (i don't use console apps, so i dont know too much
about them).

this is a thread about this but if you want more specific...
Ok, here's some code to check the input of numbers:

#include <iostream>
#include <cctype>
using namespace std;

int main()
{
char input;
cout<<"Please input a number (or q to quit): ";
cin>>input;
if(input == 'q')
return 0;
else if(isdigit(input))
cout<<"Thankyou for typing the number "<<input<<endl;
else
cout<<"I said a number or q. Go back to school!"<<endl;

return 0;
}

You can use this code as a guideline. You can assing input's value to an int var and use it without any problems.
