The Game Progress Report #27

Still tinkering away on the idealised 1D CA physics engine before I expand it up to the two something dimensions of hexagonal space again.

Realised that I have not updated this in quite a few months, so here is quite a few months worth of updates.

If you follow me on Twitter then this is nothing new🙂

The Game Progress Report #26

More progress on the CA physics engine.

Collisions now seem to be working reliability with a conservation of momentum that is accurate (enough) and visually pleasing.

Now experimenting with dispersion and forces.

I have a basic orbit working and gas of sorts. Still trying to close the loop between mass causing gravity, at the moment with this latest version, gravity is hard coded in as I try and get dispersion, momentum and acceleration to not trip over each other.

The Game Progress Report #25

I have been working on optimising the CA physics engine.

Also, my son has a Kickstarter to get his game to PAX Australia , please support it🙂

The Game Progress Report #24

I’m now starting the 4th and final version of the physics engine… getting the flow right.. The Venn diagram for Efficient, Fun and Realistic is harsh.

The Game Progress Report #23

My son has ported his Awesome Name Generator Android app to iPhone and iPad and released it onto the iTunes Store.

Been back to The Game’s core engine for the last few months on and off.

The tutorial engine, which can be used to multimedia enable Twine stories, is now feature complete.

Slowly working towards a Kickstarter project with one story author to publish their game using just the tutorial engine.

I’m also considering Kickstarting the tutorial engine itself as a separate spin off. The aim being to fund it to get developed to the level of a stand-alone tool as well as a port to Unity.

As for The Game, at this point I’m working on the world physics.

In the last few months I have managed to make progress with….

  • Visualisation of the World Hexagons.
  • Navigation/Focus throughout the World Hexagons. (Mouse, keyboard and game controller).
  • Basic Gas physics (with thermodynamics).

In the demo video below, I scroll around a bit while I simulate a 100kg ball of a 100K ideal gas being released in the vacuum of space. The gas expands until it reaches pressure equilibrium with a cohesive force holding the gas together.

I’m using a time scalable cellular automata send force messages between hexagons. That way I can build up force tensors slowly. I’m aiming at being able to round-robin timeslice the physics updates.

The colors I use don’t represent the relative temperature, more how temperature is changing over time.

Red = heating, Blue = cooling, and Green = stable.

So the core is blue, because it is very hot and losing heat🙂

You will see it eventually turn green as it stabilises. What happens before that is rather hypnotic, particularly just before equilibrium where solitons seem to form.

Working on performance and basic data flow at the moment (because getting the data flow correct is really important).

Happy so far. The physics is running hundreds of times faster than I need.

Next steps are to tidy up some of the navigation and simulate gravity in some form. I’m thinking of extending the cellular automata approach to get the cells to explore and agree upon a stable curvature of space based on distribution of mass within it. This should create something very gravity like. Not totally realistic, but gamey enough for things to fall to planets.

Gas velocity will be tricky, but I wants it.

I’m experimenting with moving the physics between different levels of cellular detail based on how how uniform the force vectors are. This is similar to how I distributed detail in my hexagon image and video encoding.

I will be need to do a decent visualisation of this at some point.  It may be a dead end but it should allow the realism to naturally scale based on what is visible and where it is needed.

The Game Progress Report #22

We are progressing with the game in our spare time, which has been very little but we are making progress.

My son has built an android game that we are publishing to test out all the commerce ‘stuff” we need to start selling games online through the many app stores that are now available.

29-07-2014 11-34-04 PM

I’ve been expanding the Twine interpreter which is going to be used as the games tutorial engine and I’m working with two writers and an artist to publish their interactive fiction/Otome games using the engine as it currently stands. Release early, release often.🙂

Here is a video of a play-through of part of a story-board using some found images on the internet as place holders for actual art.

The engine so far runs under iOS, Android, OUYA, Xbox360, SonyVita, PC, Mac and I’m now working on a WebGL port that will allow it to run in a web browser.


My Twine engine adds a number of handy multimedia and dialogue macros. I can take an ‘twee’ file exported from Twine and have a running game in a few minutes.

13-01-2014 8-10-24 PM

It has tooling that enables a graphics production pipeline to be created automatically from the story file as well as testing tools that can validate the story code by exploring all the possible story paths.

I’m looking for other Twine writers and graphic artists who want to publish their stories to collaborate on publications.

These two stories are currently at the story boarding stage so the plan is to move back into the core ‘Hex’ game features soon.

I’ve Always Found Remote Controls Unnatural: Controlling Android TV and the XboxOne+Kinect

As an experiment I’ve been submitting myself and my exasperated family to the full  ‘real world’ XBoxOne + Kinect Voice + gesture experience using the HDMI pass-through for the last 6 months.

  • The XboxOne is always on.
  • All Video input from my Windows Media Center & Apple TV pass-through the XboxOne.

27-06-2014 10-25-35 AM

The theory is that you can use voice and gestures to switch between TV and XboxOne Games and Apps.

The reality is that you get an annoying number of false positives which result in the XboxOne dropping you out of TV or bringing up a “What was it you said again?” style prompt.

27-06-2014 10-30-04 AM

  • Sometimes it will lock onto your hand, because it is there.
  • Sometimes it will recognise audio from the TV, conversation in the room or a few times from a video played on my phone about how to control the XboxOne🙂

A very annoying issue is that once it accidentally swaps you out of TV your voice is competing with audio from the show which continues to play in the background. You find yourself shouting “Stop Listening” or having to pause and do same.

27-06-2014 10-32-01 AM

The most annoying issue however is an issue from the 360+Kinect days which is that the coverage of the Voice/Gesture control is not universal. If you accidentally switch to an app that needs an update you get shoved into the update UI which will not accept Voice/Gesture commands and you need to find a controller. Individual app updates happen a lot.

On the positive side I have noticed that with each update, command registration gets better. So given enough time I believe they can make this workable. But we are not there yet.

Also, we do use it.

We use it to switch between games and TV, to Skype my mother and to play/pause content when the remote is hidden under potato chips.

I still believe that this is the future, we are progressing, but it’s not there yet.

As for Android TV, the newly announced revamp of Google TV……

For me personally, using the phone/tablet to control the TV is better than a remote, at least in the experiments I have done.

But not how Google have implemented it.

Phone as Dpad is not the way. It’s just a more expensive, heavier, less convenient, more complex remote control

What works particularly well is if the browsing and control aspects of the interface are split between the tablet and the TV.

My favourite TV experience is pushing content from my phone or laptop to the TV via the Apple TV. There is some kind of joyful usability magic there beyond the technology.

Browse near, play far.

I’ve always found remote controls unnatural. There exists something wrong at the heart of the experience.

I think there is something basic in our sense of proprioception and in particular our sense of extended proprioception that is violated by a distance further than a short stick suitable for fishing termites out of a mound.

27-06-2014 11-02-54 AM

Browse near, play far. It feels more natural.

I hope that Google can bring some magic to voice and gesture, but don’t believe it will work in the real world yet.
