1v1 web game where players control shapes and wage war against eachother

How to Run Locally (Recommended)

1. Run the Client UI

Inside ./client/frontend/src/pages/Home.js, there is this.local inside the constructor. Set this.local to true. If you have just cloned this repository, this has already be done for you.

cd ./client/frontend
yarn install
yarn start

2. Run the GameServer

Inside ./game-server/main.go there is const local at the top of the file. Set const local = true. If you have just cloned this repository, this has already be done for you.

cd ./game-server
go run .

You might also want to build the executable if you are going to be restarting the local game-server multiple times

go build -o ./game-server.exe
./game-server.exe

3. Play the game in Browser

1. Open up two instances of your favorite browser (Chrome, Firefox, etc.) and navigate to localhost:3000.
2. Enter a Nickname and click play on each instance.
3. Enjoy the game!

Notes

I do not recommend having just one browser with seperate tabs running the game, as this does not work 100% of the time.

How to Run on Google Cloud

Take a look inside the ./install and ./install/prod folders for instructions.

Notes

I have removed the custom certs that were used to get https working, so you will have to build your own or find a workaround that doesn't require certs.
