Halo: MCC Stat Notifier

✨ Welcome to the Halo: Master Chief Collection Stat Notifier!

Made this during March 2020 -- if you're fortunate enough to be healthy, sometimes social distancing can get boring, and instead of texting my buddies to play Halo with me I put the effort in to write an automatic notification system around the Halo: MCC API. I hope you find it useful and / or fun!

This project uses publicly-available Halo: MCC game info and player stats to send SMS messages to your squad (friends) when you start playing Halo: Reach, tells them your stats, and then updates you on your stats after every game.

In order to get this running, we'll be using two tools provided by Standard Library, an API-hosting platform that supports event triggers. All of the code here is fully configurable and can also be downloaded and run locally.

• Autocode, an in-browser code editor for APIs
• Halo: Master Chief Collection API, an API which you can use separately

How does the Stat Notifier work?

The Stat Notifier code can be found in functions/events/scheduler/minutely.js, which will automatically be deployed as an API endpoint that gets triggered every minute via Standard Library.

1. Execute an API every minute with the Scheduler: Minutely event that...
2. Uses the halo.mcc.games.latest API to fetch your most recent game data.
3. Checks to see if you've reported on this data yet using the utils.kv.get API, which is a key-value store specific to your Standard Library account.
4. If it's a new game, store the game time using utils.kv.set for next time.
5. If you haven't played in a while, prepare a group SMS to tell all your friends you're in a new session.
6. Otherwise, just prepare a message to you to tell you what your stats are.
7. Finally, send out the SMS using utils.sms to either you or your squad.

Installation

Installation is simple. You can click on the button below to instantly open this project in Autocode.

From here, you'll be prompted with Environment Variables. You'll want to use the following:

• GAMERTAG: Your XBL Gamertag that you want to track. e.g. Xx MyGamertag xX
• PHONE_NUMBERS: A comma-separated list of phone numbers to send SMS to. The first one should be yours, the rest can be your squad. e.g. 14165550000,16475551337. Your squad will only be notified upon new sessions.

Next, just name your project and hit Start API Project from GitHub.

NOTE: Your project IS NOT YET DEPLOYED. You can test it by navigating to functions/events/scheduler/minutely.js and clicking Run Code.

You can Deploy at any time from the Deploy button in the bottom left corner of Autocode's IDE:

How Can I Make Changes?

You can make changes to your project any time by visiting autocode.com.

The code for the Stat Notifier itself is pretty simple, coming in at well under 100 lines of code. If you open up functions/events/scheduler/minutely.js in Autocode, you can see both comments and annotations for certain lines of code and what they do.

A few things to note...

console.log(`Retrieving latest Halo: Reach game...`);
result.halo.gameHistory = await lib.halo.mcc['@0.0.10'].games.latest({
  gamertag: GAMERTAG,
  game: 'Halo: Reach',
  gameVariant: 'All'
});

This is the main code that talks to the Halo: Master Chief Collection API. You can play around with different endpoints by visiting Halo: MCC API documentation.

console.log(`Texting me my game results...`);
await Promise.all(phoneNumbers.map(phone => {
  return lib.utils.sms['@1.0.11']({
    to: phone,
    body: `${newSessionMessage}` +
      `${result.halo.gameHistory.games[0].won ? '🎉' : '😵'} ${result.halo.gameHistory.gamertag} just ` +
      `${result.halo.gameHistory.games[0].won ? 'won' : 'lost'} a ` +
      `${result.halo.gameHistory.games[0].gameVariant} game in Halo: Reach.\n\n` +
      `💥 Kills: ${result.halo.gameHistory.games[0].kills}\n` +
      `☠️ Deaths: ${result.halo.gameHistory.games[0].deaths}\n` +
      `🔫 KD: ${result.halo.gameHistory.games[0].killDeathRatio.toFixed(2)}\n\n` +
      `🕒 ${result.halo.gameHistory.games[0].playedAtRecency}` +
      `${newSessionFooter}`
  });
}));

The above code is what generates your message and sends text messages out. The phoneNumbers variable is derived from process.env.PHONE_NUMBERS, you can change your Environment variables any time by opening env.json in Autocode.
