so where is this game?

steady coyote so where is this game?

In development. Working to release a demo on Itch in a few days

so did you program the ai?

steady coyote Apr 20, 2023, 7:27 AM

#

are you gonna make it like an online game?

marsh radish Apr 20, 2023, 7:57 AM

#

No online mode planned. We already have many online chess games. This game will be a chess club sim with NPCs and a strong focus on short tournaments: round robin, swiss, match play, and exotic modes as King of the Hill, last survivor and staged round robin.

Low rated NPCs can make big mistakes, just like in real life. This has been one of the hardest things to code.

marsh radish Using Stockfish and Arasan as engines

how did you integrate stockfish?

marsh radish Apr 30, 2023, 6:52 AM

#

static gust how did you integrate stockfish?

I coded a python script that acts as a server/gateway between Godot and the engine, Arasan, Stockfish or any UCI compliant engine. The Python gateway and Godot use UDP to send and receive moves and commands

static gust May 1, 2023, 1:53 AM

#

then you have to embed python

#

and python is fat

King of the Hill tournament mode

The game now spawns random players when there are not enough players in the club to fill the tournament field

Adding the in-game help

steady coyote May 15, 2023, 3:31 PM

#

@marsh radish as you're making a chess game, should i assume that you play chess?

#

If so, what's your chess rating?

marsh radish May 15, 2023, 3:33 PM

#

I played a lot of chess in the past and now I was looking for a casual chess game. I didn't find what I was looking for, so I'm making my own chess game

#

My max rating was 2200. It should be at 1600-1800 now

steady coyote May 15, 2023, 3:36 PM

#

man

#

can you give me some tips on how to improve. I was almost gonna cross 1300 and reach to 1400 and yet, i started loosing at a constant rate and now my rating is 1200 something...

#

Would you like to play a game with me

#

that's what has happened to me

marsh radish May 15, 2023, 3:41 PM

#

I could be wrong, but I believe online blitz ratings are not as reliable as classic chess ratings. I do not like online chess because there are a lot of fake accounts, cheaters and uneducated players that don't respect the basic etiquette rules

steady coyote May 15, 2023, 3:41 PM

#

wait, so you mean you're real life rating was 2200?

marsh radish May 15, 2023, 3:41 PM

#

...and for that reason I'm making a casual offline chess game with tournaments 😄

#

My rating was Fide official rating earned in classical chess tournaments

#

Not sure how Blitz online rating compares with classical chess rating

steady coyote May 15, 2023, 3:43 PM

#

well we don't have that stuff here so idk

steady coyote May 15, 2023, 3:43 PM

#

marsh radish Not sure how Blitz online rating compares with classical chess rating

wanna have a go?

static gust Jun 4, 2023, 11:48 PM

#

arrows are quite easy to make

#

and quite fun to use

#

i recommend

#

also tip, if you want them transparent, use a seperate viewport and make the viewport transparent, then they wont overlap funny

marsh radish Jun 6, 2023, 6:56 PM

#

Yes, the idea is to use arrows to signal the best move when user activates the analysis mode. Not sure about using a separate viewport or a canvas layer. I had no problems in the past with canvas layers.

marsh radish Jun 11, 2023, 6:42 AM

Another small step

how did you make all the backgrounds

#

they look vaguely 3d while also not, its cool

fickle fog Jul 3, 2023, 10:22 PM

#

Dam, that's a lot of effort man! Are you gonna upload it to mobile?

static gust Jul 3, 2023, 10:36 PM

#

why though

fickle fog Jul 4, 2023, 1:29 PM

#

static gust why though

So I could try it

marsh radish Jul 4, 2023, 5:50 PM

#

static gust how did you make all the backgrounds

I made 3D rooms in godot and took screenshots

marsh radish Jul 4, 2023, 5:51 PM

#

fickle fog Dam, that's a lot of effort man! Are you gonna upload it to mobile?

Probably not. It's not easy to port the chess engine (arasan) to mobile nor the UDP gateway between Godot and the chess engine

fickle fog Jul 4, 2023, 6:02 PM

Ah, I see.

static gust Jul 4, 2023, 10:22 PM

#

i integrated stockfish via wasm. and then i regretted not doing a engine module

#

if you use a engine module you get cross platform-ness for free

marsh radish Jul 23, 2023, 6:17 AM

#

Fixed an annoying bug in the analysis board. Next step is to link the game with the Steam library 🤞

crisp flare Jul 29, 2023, 11:04 AM

#

HI, i really like the ui and the concept of the project

#

but/ I am pretty good chess player :) so i would say that for black taking the white queen is a bad move, because white is up 2 pieces.

#

so did you integrated stockfish here?

marsh radish Jul 29, 2023, 12:06 PM

#

crisp flare so did you integrated stockfish here?

I'm using Arasan, with a few tricks to force blunders in low elo NPCs. NPCs over 1800 are hard to beat

#

(after 24 gxh3 the AI player resigned)

In my personal experience playing chess at a club, if someone try to keep on playing being two pieces down, all players will mock him for the rest of his life 😆

and "was too dark"

"It was an unfair game. The board was tilted with your pieces on the high ground"
