[C++] Chess game Terminal

Name: Snake4D 2012-01-11 12:05

Hi,
I'm trying to make a little chess game,
in C++, is in terminal because still I don't know a good GUI package for C++ sorry I'm n00b...

btw I got to print out the board:
like this:
[code]
-|--a-|--b-|--c-|--d-|--e-|--f-|--g-|--h-|
8|-bR-|+bk+|-bB-|+bQ+|-bK-|+bB+|-bk-|+bR+|
7|+bP+|-bP-|+bP+|-bP-|+bP+|-bP-|+bP+|-bP-|
6|----|+--+|----|+--+|----|+--+|----|+--+|
5|+--+|----|+--+|----|+--+|----|+--+|----|
4|----|+--+|----|+--+|----|+--+|----|+--+|
3|+--+|----|+--+|----|+--+|----|+--+|----|
2|-wP-|+wP+|-wP-|+wP+|-wP-|+wP+|-wP-|+wP+|
1|+wR+|-wk-|+wB+|-wQ-|+wK+|-wB-|+wk+|-wR-|
[\code]

and one can tell like in chess with the sentence "(e2:e4)" to move the piece from e2 to e4

but now what I need to make a AI?
I'll paste the code in pastebin so you can have a look:

Chess AI??
No wai.
You mean one that doesn't move chess pieces randomly?
(It's AI too, that's how I usually for the first few moves play)
I can only contribute simple ones.
Search algorithm, makes some move permutations for the next 3-4 moves(fuckload complexity) and put some weights on taking a figure + (weight for different figures) and - for losing a figure
This should be good enough for any CS 101 course, unless your program is gonna play against Bobby Fischer(btw he's dead)
Or just hardcode all possible moves(lol).

    >Or just hardcode all possible moves(lol).
hardway...

btw a simple one that moves pieces like you said is great... do I need something in particular? or store the moves in a boolean board will work?

I think it's easier to just write the chess program itself, the AI, and the GUI as three different things. After that, you can just link everything together using getters and setters.

Have you ever read SICP? If so, the books talks about this model. Now just extend this basic idea to what you're doing. If not, then I guess I'd have to agree with the regulars here and tell you "Read SICP."

Kodak, this is your daily reminder that the statement every subset of a countable set is also countable is absolutely true, never fails and is mathematically proven.

OP, read xboard protocol - you don't need to write gui.

Cool story time:
I tried to write chess AI once, even connected it to xboard and tested on several Guests at FICS  Guess what, it appeared that opening books ARE important, as guests were not patient enough to wait while my almighty AI calculated start position score to  start with its favorite Nf3. On the bright side my AI is undefeated after 3 games since people aborted the game at turn 1.

The weird part is that the imageboards are up.

On topic:
Since op is doing it in a terminal means its super-basic.
He should just make something that moves the pieces randomly
unless a piece can score or is in imminent peril.

How does terminal imply super-basic?

A lot of OS's make a distinction between the terminal and the console. But I wouldn't expect a mental midget like yourself to know such a subtle, but important difference.

And what happens if I do something like

int getline(char s[], int lim) {
  for(i = 0; i<lim-1 && (c = getchar()) != EOF && c !='\n'; i++)
    s[i]=c;
}

Is s[] still a string you mental  midget? The answer is no because there is no '\0'. Now go scrub another toilet you fucking idiot.

Well first you would have to declare "i".

Also, what happens if the underlying device is a socket()? How do you see fucking output? That is why some operating systems make a distinction between the terminal and the console.

Again, you're stupid. And again, you have no real future as a computer programmer.

Well, in this case, 'i' would have what is known as 'external linkage'. In other words, I wouldn't have to declare it in this function.

More on less, in C, a string is an array of characters followed by a '\0'. In this case I don't have a '\0'. Therefore it's not a string. Now shut up and quit arguing with me. Unlike you, I work as a programmer.
