git clone https://github.com/temporalio/docker-compose.git
cd  docker-compose
docker compose up

The Game Controller Service is a Java App that uses the Temporal Java SDK

cd game-controller
mvn compile exec:java -Dexec.mainClass="io.temporal.snakegame.controller.ControllerStarter"

Snake Game

The Snake game is a Java app which uses the three started services for overall game control, game info such as images, text, fonts background, etc as well as movement controls.

cd game

Playing The Demo

Once the game starts you can use your keyboard LEFT RIGHT UP DOWN keys to move the snake across the board. The goal is to eat the apples. Once you eat an apple your snake will increase and another apple icon will get displayed on the board. If you run into any of the edges of the board, or into your snake itself the game is over.
