Chess in C

Basically, I added the Castling function.
I’ve also modified the saving system, because of the new changes.

Basically, I added a feature to mark on the board what was (the opponent’s) last move. I also added the en passant functionality, and I am making a process of changing the saving of games to support castling in the future.

THE COLORS UPDATE! 🌈
I finally added some colors at the game. Now, some messages are better.
I’ve also adjusted the README and solved some coordinates bugs.

First of all: THANKS FOR THE FEEDBACKS! Most of the recent updates happened thanks to them. Please continue voting and sharing your experiences.
Basically, I added a draw option and I resolved some of the reported errors.
AND, I updated the online version of the game, available on https://onlinegdb.com/aZ6Y7iAGD (the link in on the README too).

I changed the representation of each piece from the letters to the icons for each one on the chess board!
I’ve also added the stalemate detection (when the king isn’t on check, but there are no legal moves).

I’ve finished the translation of the game! Now, the users can choose between English and Portuguese at the beginning of the game!
It was a little time-consuming (and tedious), but the result is admirable 🙂
The updates are on the latest release: https://github.com/acms2345/Xadrez-em-C/releases/tag/v1.2

I’m FINALLY making a translation of the game to English.
The updates aren’t on the GitHub release or repository yet, because I want to finish the translation before I make this. But I intend to do it soon!

Now, I’ve added an internal mechanic to better verify checkmate.
During this time, I also made some minor modifications to the README.

I’ve added a system to check for moves that leave the king himself in check (a illegal move in Chess rules, but it was possible on the game).
I’ve also made a workflow to generate the executable versions of the code, so you guys can test it!

I try to explain better on the README how to use my game, including how to download and compile it.
I also made an adjustment to the 50-move rule (It wasn’t working because I forget to reset the variable after the turn).

Finally, I adjusted the board to the standard chess layout (white pieces in positions 1-2 and black pieces in positions 8-7).
I also fixed some data inputs after becoming aware of certain bugs.

I made some modifications to the code structure. I changed the name of the chess.c file to game.c, added the game.h file, and I’m trying to organize the code better.

I basically edited the README and some parts of codes to add some advices in English. Now, there’s a entirely version of the README in English, keeping the Portuguese version.
I plan to add more English information on the source code, but currently it’s entirely in Portuguese.

Basically, during that time I tried to create a demo link so you could test the actual version of the game. In the most of the time, I tried to share the project on GitHub Sites using a HTML integration, but that didn’t work.
So, I put the demo on OnlineGDB. The link to access the demo is https://onlinegdb.com/mCVxTRf8M (no login or download required).

I basically added the 50-move tie-checking system and fixed a problem I was having with the initial two-square pawn movement.
