reversi-bot

Play "Reversi" with a simple, but reasonably strong bot!

DEMO - Click here

• TS files run wasm functions to calculate bot's thought, which are compiled from Rust code. See reversi-bot-front for UI.
• When getting closer to the end of the game, the bot will read all the possible moves, choose the best one, and give you a prediction of the result, which is definitely correct if the prediction says you will lose. You have to give up 🥲

Built with

UI is built with:

• React with TypeScript
• Three.js

bot is built with:

• Rust and WebAssembly

Getting Started

git clone [email protected]:porink0424/reversi-bot.git
cd reversi-bot
git clone [email protected]:porink0424/reversi-bot-front.git www

When you update something in /src in this repository, you need to run:

sh build_and_copy.sh

to update /www/src/pkg.

And then, you can run in /www:

yarn; yarn start

to start the development server.

How I Built

By running:

cargo generate --git https://github.com/rustwasm/wasm-pack-template

I created a new Rust project with wasm-pack template. Here I deleted .git and reinitialized it.

At the time I implemented some logics in Rust, I ran:

wasm-pack build --target web

to compile Rust code into wasm with build_and_copy.sh. Then, I copied ./pkg to ./www/src/pkg. Now I can use wasm functions in JS. It is a bit tricky, but it works.

What I Left

• Improve UI (e.g. durable with the change of the window size, button sizes, etc.)
• Use multithreading in Rust
  • We cannon use std::thread in wasm, so we need to use web_sys::Worker or something like that...

What I Struggled With

• When we use rand crate in wasm, we need to specify the features in Cargo.toml like:

[dependencies]
rand = { version = "0.6.1", features = ["wasm-bindgen"] }

• When we do not use jekyll in GitHub Pages, we need to add .nojekyll file in root to avoid 404 error.
