Armed with a bottle of guarana pills, the company of awesome friends, and the promise of a fabulous Indian dinner as culmination, I set out with my brother Adam to start a project from scratch and finish as much as possible. We decided on a game for the iPhone, made using the beta for Unity’s iPhone version of their software. Our game is a 3D customizable robot brawler, in the spirit of the fantastic Sega Genesis game Cyborg Justice.

After three days of TIGJam, we ended up with a nicely fleshed-out prototype, including enemy robots, three selectable weapons (grabber arm, minigun, and rocket launcher), and, of course, exploding barrels. We made this video earlier today, showcasing a total of four days of work:

There were some other fantastic games being worked on during the jam, including a number for the upcoming Gamma 3D showcase. My personal favorite (other than of course World of Goo, which Kyle and Ron of 2D Boy were working on) was Alec Holowka and Adam Saltsman’s curling game, which looks completely sick after only three days of work!

Photos from the jam are up in my Flickr stream. Adam and I plan to be finished with our robot project by the time that Unity iPhone reaches release — I’ll update as it comes along!

Not least among these is the notion of Quantum Entanglement — that observable qualities of systems may be statistically correlated, even though the systems may be separated by vast spatial distances. An example is a pair of entangled electrons — one will have spin up, one spin down, but the individual states are indeterminate until a measurement is made. However, once the spin of one electron is measured, the spin of the other will become determinate instantaneously, and more importantly, superluminally. Einstein labeled this theoretical phenomenon “Spukhafte Fernwirkung” — “spooky action at a distance.”

These graffiti, placed on opposite ends of a bridge, embody the notion of entangled states, each with Einstein’s appellation and a measured spin wavefunction — up for Alice and down for Bob, whose wavefunction has collapsed once Alice makes her measurement.

For more on entanglement and Einstein’s view, I also suggest reading about the EPR Paradox.

1. First, open up the Video Game Name Generator.
2. Next, find a name for the game that you want to make.
(Peeing your pants out of mirth is recommended during this part.)
3. Finally, MAKE THAT GAME.
Optional Secondary Objective: BRAND LEADERSHIP

My brother/coworker Adam and I decided we’d try our hand at one. We picked Obsessive Compulsive Penguin Simulator, for obvious reasons. You play as a penguin with OCD, who must stamp down accumulating snow drifts, in order to keep the ground even for all! To promote Brand Leadership, I also made this stunning promotional artwork:

The competition lasted three weeks, but we spent a total of about five days working on it — three of Flashbang’s experimental Fridays and then this last weekend. Now go play the game — it plays in-browser for OS X and Windows!

Hi Guys, great game - I have been playing for weeks. I just wanted to say that, believe it or not, I am a palaeontologist and I happen to work primarily on dromaeosaurs and pterosaurs - in other words, among other things i am an expert on Velociraptor and Pterandon. Yes, really.

And can be (and generally am) a pedantic sod, but in general your reconstructions of both are great. Very detailed and very accurate and that is one of the reasons I like playing (OK, so running them over is cool too… ;-) I get riled constantly by bad reconstructions of dinosaurs and especially pterosaurs that are generally being done by supposed experts and making a complete hash of even the basics, so it is a delight to see these done so well! Great stuff.

Anyway, thanks for a fun game and if by chance you do want some advice on future dinosaurs I am happy to help out!

Cheers,

Dave

[citation needed] stickers have been slowly showing up in new places. I’ve still got a number left, so if you want a few, just send me an email or a message via Flickr. A few from around Tempe and San Francisco are in the Flickr tag pool:

I especially dig this one from Flickr user cutlerite:

Reason Magazine also recently published a short article about the project, in their March issue. Don’t be afraid — they’re much nicer Libertarians than some of the Randroids I’ve met!

I also finally had a chance to really test my bicycle camera mount — the lead-up to the Game Developers Conference had left me with little time for biking anywhere other than work. I went riding with Matthew and took a few shots as well as this video:

On a side note I don’t recommend trail riding with this particular mount — the constant jostling broke the conduit hanger I was using to mount the tripod head. Luckily it’s the cheapest piece at only 50 cents, but the weight of the assembly demands something a bit sturdier than cheap plastic if you’re going to be navigating bumpy terrain!

Among my numerous interests is custom hardware for games and interactive art. When my friend and coworker Matthew Wegner suggested the idea of making a breathalyzer peripheral for a party game at GDC, how could I respond with anything but, “Hahahaha, Hells YES! I am ON that!”

I started by researching the various consumer breathalyzers. In the end I decided to hack the Alcoscan AL2500. It provides readings within a reasonable error tolerance and costs about $30 on Amazon — much cheaper than fuel cell meters. Upon opening it up, I found that it’s set up pretty simply. It’s driven by an ATMEGA48V-10AU microcontroller, with the semiconductor sensor connected to an analog input, and digital outputs that drive a simple seven-segment style LCD.

As I saw it, there were basically two options for obtaining the data from the breathalyzer and sending it to the computer. On the one hand, you could read the analog value from the breath sensor, or on the other hand, you could reconstruct the LCD digits from the digital outputs. Since the analog circuit driving the sensor was a little complicated and beyond my expertise (and I’d procrastinated enough that learning more before GDC was out of the question), I decided to reconstruct digits. I first followed traces on the PCB to find which pins on the microcontroller were driving the LCD. I then systematically grounded each pin while turning the unit on to determine which pins drove which LCD segments.

I then soldered wires to the relevant LCD outputs on the board (the connectors were nice and big compared to the microcontroller pins). I spent a bit of time determining which outputs from the LCD I wanted to read. As it turns out, you only need five segments from a seven-segment digit to determine the numerical value of the digit — the bottom and bottom right segments are superfluous (see Matt Mets’s recent post, who solved the problem independently). I ran a total of eleven wires — two digits for the BAC level and one wire for the “Wait” indicator — into digital inputs on an Arduino Diecimila. The Arduino code ended up pretty simple — it reconstructs two digits and the status of the “Wait” indicator and transmits these serially via USB.

I then read the serial data in using the Java RXTX library and spit it into a text file, which I then read in from Unity. The game then makes the paddle size larger the drunker you are!

The hardware is of course begging to be used in other ways — how about a program that locks you out of Ecto and your forum accounts when you’re right trashed? No more embarrassing comments that you can’t take back! I may go back and make a more sophisticated game in the future — Pong was about the right scope for the single day of development time I had left after handling the hardware and serial transmission!

I’ll have the game up for play at the 9Bit indie games party Tuesday night — if you’re at GDC just find folks from Flashbang, Gastronaut, or ThatGameCompany to get an invite and drink tickets! I’ll post an Instructable and some more information about the software when time permits. Extra special thanks to Becky Stern and Matt Mets for their advising on the hardware interface!

I published an Instructable for anyone interested in making one, and have a photoset up on Flickr.
