Unity Telegram Game - Backend

For complete overview of the project, please visit the Unity package GitHub repository.

This is a Node.js app that serves two purposes:

1. Run a Telegram bot
2. Serve a game (actually, an index.html file)

Note that this repo is essentially only that. So it isn't mandatory to be used with a Unity game. Actually, the project from which this project has been forked implements a fully js T-Rex game.

This project contains a very simple Unity Game, which uses the unity-telegram-game package.

Create a Telegram bot

The first step is to create a Telegram bot. Talk to the BotFather and store the token it will give you.

In this app, we will only do two things related to the bot:

• Listen for commands and serve the game when asked with /game
• Listen for inline queries (this enables you to type "@YourNameBot" in any chat and get prompted with the game)

Installation

• Deploy a Node.js app. This documentation will not cover this part (this is because it is out of the scope of the project, not at all because I already forgot how I did it). However, here are some steps to deploy it on a VPS (something like that) :
  • Install Node and yarn
  • Install pm2 and use it to start the Node app
  • Configure a nginx server (pay attention to how you're declaring the public folder in the config)
  • Don't forget to cry because your nginx config is not working
  • Pay attention to which ports are used and need to be opened: don't forget you have two services running, the express server and the telegram bot.
  • Add a SSL certificate
• Upload your WebGL game in the public folder
• Add a .env file with the following content:

  BOT_TOKEN=<your-telegram-bot-token>
  SCORE_TOKEN = "<your-score-token-1>;<your-score-token-2>;..."
  

  The score tokens are the numbers you will use to obfuscate the score. They must be also set in the Unity game.
• You're good to go.
