/prog/ - [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?

Why don't you just get a github account or something to that effect instead of spamming a bunch of pastebin links?

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.

In other words, just turn this into "abusing message paassing" 101.

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.

I really think the OP would have an easier time with this project if he had read/absorbed the stuff in SICP.

Shouldn't that be "... how much simpler Checkers is compared to Chess?"?
