Hi, I'm Henry. In 2012 I quit my job as a programmer at BioWare to spend a year making my own indie games. This blog is about what happened next...

Spaceteam is coming to Your Library

Your Library

Every year libraries around the world participate in International Games Day @ your library raising awareness of games and gaming in libraries. Read more about the history of IGD.

This year, on Saturday November 19th, Spaceteam will be one of the official games played in libraries across the planet and I'll also be running an experiment to connect all IGD Spaceteams together through a global event leaderboard.

Here's a sneak peek at what the event page will look like:

Leaderboard Sneak Peek

This is a web page that will be updated in real time to show a ranked leaderboard of every Spaceteam participating in the event, along with some other stats like the total number of sectors travelled. I'm also planning to include a world map showing all the locations where Spaceteam is being played.

Your Events

IGD will be the first official event to use this feature but starting with Spaceteam 2.1 it will be totally open to be used by anyone to run your own Spaceteam events.

Just pick a short Event Code (like "IGD" or "Challenge2016") and tell your participants to use it. Then go to the website (probably leaderboard.spaceteam.ca when it's ready) and enter your code. You'll get a custom leaderboard filtered to only show teams who used that specific code!

Event Settings

This task has a specific deadline (November 19th!) so it has taken precendence over other things but I hope to wrap it up this week and then my next Spaceteam priority is Bluetooth support!

Technical Details

Getting the leaderboards working proved more difficult than I expected. My first plan was to use the built-in Unity Analytics to send a custom event whenever a team finished a game. Then a worker app on Heroku would periodically download the event data through Unity's Raw Data Export system and store it in a database. The web page then queried the database to display the top teams. But there was just too much lag time between sending an event and it showing up on the website.

Next I experimented with a service called PlayFab, and finally settled on GameSparks.

GameSparks has a bunch of useful features that I might be able to use in future games, the only drawback is the potential cost. They have a great "indie" program which is free for up to 100,000 Monthly Active Users (MAU). Well... lucky for me Spaceteam has over 100k MAU. So for now I'm only enabling GameSparks if a player enters an Event Code in the settings. So please don't all do it at once! Just kidding, only a small fraction of Spaceteam players read these posts so there is basically no chance that the numbers will get that high. Use it as much as you want!


In the world of Blabyrinth I'm in the midst of building the engine foundation.

One of the basic concepts in the game is the "level" which consists of a 5x5 grid of rooms (this may change) containing scenery, doors, and items. A level can be hand-crafted or procedurally generated. A level also has rules that determine how doors are unlocked, secret passages opened, and what happens when scenery is interacted with.

A rule might be:

  • if all four players push (swipe) this statue at the same time then it will slide out of the way revealing a hidden item cache
  • if three specific items (eg. a bell, book, and candle) are placed on an altar and certain words are recited then a mystical symbol will appear on the wall
  • if keypad buttons E, N, I, G, M, and A are pressed in sequence then a secret passage will open

These rules are easy to write in code, but I need to design them in such a way that I can easily store them in a database and send them across a network. I also want to support players making new rules for their own levels. JSON is a good format for doing this, partly because it's an easy format for humans to read and write. So I'm making sure that I can store not only the level layout and contents, but also the rules, in JSON. Converting data between different formats like this is called "serialization" and this is what I've been working on recently.

Heavy Turbulence

*beep* *boop*

This is your Captain speaking.

We've been going through some rough weather since take-off. If you had seatbelts I would urge you to fasten them, but due to budget issues we had to cut some corners. My sensors are picking up:

  • Install/update problems on Android (error codes -504 and -505)
  • Restore Previous Purchases not working
  • Difficulty connecting to the Waiting Room
  • Crashes at the end of the game (when you crash in Spaceteam you crash in real life...?!)

With version 2.0.2 I think I've fixed the first two issues. I'll investigate the crash next, and the connection issues will continue to improve as CaptainsMess (my networking library) gets better.

I'm also getting messages begging me to bring back Bluetooth. I hear you! I'll bring it back as soon as I can. I've been getting some promising results so far from the Android Bluetooth Multiplayer Unity plugin. iOS might be a bit trickier but I'm sure I'll figure something out.

Other things I've been working on:

Blabyrinth Project Setup

Last week I spent several full days working on Blabyrinth and it felt great. Now that I'm more familiar with Unity I have a much better idea of how to structure everything.

Some of the Unity lessons I've learned from Spaceteam (these may not apply to other games):

  • Force all assets to be stored as text. Otherwise it's very hard to track changes in scenes and prefabs.
  • Use a lot more prefabs, even if the object is only used once. Try to keep the main scene as empty possible. But be very careful with "nested" prefabs.
  • Keep server & client classes totally separate. Never have ambiguity about which data lives where or who has access to what.
  • Put static game data in ScriptableObject classes, not in the scene hierarchy
  • Don't use Unity's built-in Animation Controller for simple 2D and UI animations, use a tweening library instead (like DOTween).
  • I ended up not making good use of PlayMaker, and it was the cause of some of the suspicious Android permissions. For Blabyrinth I'm going to keep my state machines in code.
  • Have an in-game log viewer and debug panel available from the beginning
  • Use more custom editors and property drawers
  • Use more coroutines and enumerators. But be careful about how and when they get cleaned up.

Modular Systems

I'm designing Blabyrinth to be pretty extensible and modular, both for my own sake to manage the scope of the project and also to give it some longevity with later expansions.

I'm breaking systems up into components that I can work on separately, and the scope and complexity of each can change independently:

  • Level Layout Generator — connectivity between rooms, secret passages, major landmark locations, etc.
  • Level Editor — by default the level and puzzles for each game session are procedurally generated. But I also want to support handmade or "curated" levels, allowing for levels made by guest contributors and eventually fan-made levels.
  • Puzzle Generator — locked doors and obstacles, clues, and solutions
  • Mysterious Diagram Generator — certain clues will involve diagrams that contain hidden information and look something like this: https://twitter.com/ebooks_goetia
  • "Riddle" Generator — a system for language-based clues, more on this later...
  • Item Appearances — general purpose items like keys and books will have many variations in style, shape, material, and colour
  • Level Appearances — cosmetic variations in the walls, floors, and scenery
  • Character Appearances
  • Custom Set Pieces — most rooms will be generated from a combination of reusable scenery elements, but there will also be unique special-purpose rooms used in certain situations
  • Character Abilities — each player will have one special ability that allows them to solve certain puzzles that no one else can, ensuring that everyone gets a chance to participate
  • Traps!
  • (Secret systems that I don't want to spoil yet...)

I'll start small and add things to each component as needed. This way I can quickly make a fully playable prototype and then the game will progressively get more varied and interesting from there. But the first step is to make a bare-bones version of each system and get them all working together so I can start testing the game as early as possible. That will be my next major milestone.

Happy Canadian Thanksgiving!

Spaceteam 2.0 has landed!

If you haven’t been following Spaceteam development, you should know that for the past 9 months I’ve been rebuilding Spaceteam from the ground up using the Unity game engine. It took much longer than I expected and was a pretty stressful time for me. But it’s finally ready.

Every day thousands of people are still discovering Spaceteam for the first time, making new spacefriends, and using the game in creative ways. I didn’t want it to die.

This is Spaceteam 2.0



App Store: https://itunes.apple.com/us/app/spaceteam/id570510529?mt=8

Google Play: https://play.google.com/store/apps/details?id=com.sleepingbeastgames.spaceteam

Don’t get too excited! The game is mostly the same, but it works on more phones, looks a little better, and has a few new features. But everything has changed under the hood. Because of this it’s also bound to have its own unique set of problems, so bear that in mind as it flies into the wild for the first time.

Notably this version doesn’t have Bluetooth support yet, although I plan to add it soon.

The game now speaks 4 new languages (in addition to the 12 it already knows):

  • Dutch: ASTEROÏDE! (iedereen schudden)
  • Greek: ΑΣΤΕΡΟΕΙΔΗΣ! (κουνήστε όλοι)
  • Turkish: ASTROİD! (herkes sallansın)
  • Korean: 소행성! (모두 흔드세요)

If you have friends who speak these languages please share the news, as I don’t have any special marketing campaigns to reach out to those countries. As usual, news about Spaceteam spreads by regular people shouting things to each other.

Welcome to the new Admiral’s Club!

Some brief backstory: I never planned to do this rebuild. But when the Android version of the game was put in jeopardy last year I had to make a difficult choice: to abandon the Android version, or make some major changes. Thanks to a group of generous fans and supporters, the Spaceteam Admiral’s Club, I’ve been able to keep it alive and also teach myself Unity which is a huge investment in my future games. That investment is going to start paying off… now :)

For the first time since it started, the Spaceteam Admiral’s Club is officially accepting new members. If you missed it the first time, or you want a fancy golden laser or an alien pet, now’s your chance. The Admiral’s Club is the best way to support my new games and get cool goodies. Please join if you like Spaceteam and want to see more!

Getting Back To The Future

I’ve actually been trying to move on from Spaceteam for a while. Last year I started building prototypes for my new game Blabyrinth. Now that Spaceteam 2.0 has launched I feel like I can get back to it. Spaceteam and its spin-off projects will still need support but I’m once again making a promise to devote at least half of my time to Blabyrinth. This is something I’ve been excited about for a long time. You can read more about the ideas behind Blabyrinth in this post.

The next immediate steps for Spaceteam are:

– Spaceteam ESL 2.0 (The ESL version had the same Android problems so I’m updating it too. Unity will make this process much easier.)

– Official Leaderboards for special events

– Chromecast experiments, and a special observer mode for collecting stats for research

– Spaceteam Kids

I’ll probably end up sacrificing the Apple TV version (sorry if that’s your thing). It was never the best platform for Spaceteam and the market is still quite small. I’d rather spend the time on Blabyrinth instead.

And those are the last scheduled plans for Spaceteam. Once these tasks are complete I’ll be able to transition to the new game(s) full-time. If the Patreon does well I might even be able to get some help to reach that point sooner.

Reaching this milestone is a huge weight off my mind. Thanks for sticking by me through the process.

As always, if you have any questions or want to chat, join me on the forum or send me an email.
