Stardoz! My Game Which Uses Heartbeats To Spawn Enemies

Stardoz

First version of Stardoz

Stardoz is a crazy experimental biometric-driven game I built at TOJam a few weeks back. In the game you fly around in a spaceship shooting at giant floating heads and hands. It’s similar to many flying in space combat games.

The catch is that your heartbeat controls the spawn rate of enemies. The pulsing red border on the screen shows the player’s heart at work.

If floating heads seems familiar to you, it’s because you may remember the movie Zardoz starring Sean Connery. Just watch the trailer to see how zany the movie is.

Really, the gameplay is similar in play insofar that “the gun is good” and that one survives by ‘killing’. It’s very simple gameplay with a neat twist. I made Stardoz to test out some space-based game mechanics and to incorporate some biometric data into a game.

Playtesters have liked the heartbeat spawn mechanic and only one player took issue that the game is hard for people with high resting heart rates. I’m still tweaking the spawn rate but it’s alright for the most part.

Stardom being played

The art confuses players and that’s a design goal of mine. I wanted it to cross between the ridiculous and the overly-symbolic. Thus, instead of a score it lists how many egos you’ve destroyed and how many emotions you have. .

You are flying through space (or is mindspace?) destroying representations of human forms. In some cases it’s heavy handed and in some ways quite subtle (only one person has figured out the symbolic placement of the TOJam goat).

Getting the Heartbeat

Pulse Sensor

With the excellent help of J Lee, I was able to get an Arduino Uno board to work with a pulse sensor which meant that heartbeats could be tracked using Unity. The heartbeat is tracked using this pulse sensor which was really easy to connect to the Arduino and to configure it into Unity.

“Fun fact”: for Windows use COM4 and /dev/cu.usbmodem1421 for Macs as the port for Unity to talk to the Arduino. At least this is what worked for my setup. Results may vary.

The pulse sensor goes around the player’s finger and surprisingly doesn’t interfere with gameplay controls. It can be attached to the player’s ear but it just feels weird.

Here it is in action around the left index finger of a player:

Next Steps

For this game will be to see if I can get it working with the Apple Watch (or Android Wear), if it works maybe I’ll release it for anyone to play. In the meantime I’m hoping to show it at upcoming events.

Game Praxis: A Game Competition About Philosophy

Game Praxis

Game Praxis is a game competition and a journal exploring the intersection between games, philosophy, and practice.

The goal is simple: generate more interesting content about how games can be used to explore bigger questions. For the first run of Game Praxis pre-existing games can be submitted so if you’ve already made a game that you think should be considered you can do so.

The Game Praxis mission:

Should you choose to accept it? Marx observed philosophers have interpreted the world when the point is to change it. Much the same could be said for the game industry. We need to build more than better worlds, we need to build a better world. We see crunch, the precarious careers of late capital, and a troubled and troubling apprehension of gender in game and the game industry as symptoms of an underlying pathology of the spirit. In the game industry, the measure of success is money. With all due respect to our invocation of Marx, we aren’t against the production of surplus value but we believe there are more creative ways to evaluate games, game industries and our lives in game.

The theme of the competition is ALEA JACTA EST. Any game or writing about around the theme can be submitted from now until June 1st.

We want to encourage more discourse and thoughtful analysis through the use off gaming. I say ‘we’ because I’m on of the founding editors of Game Praxis.

There is a fantastic list of people who will be reviewing the submitted games too. They are:

GOLBOO AMANI
GABRIELA AVEIRO OJEDA
TRUDY BARBER
VASS BEDNAR
SANDRA DANILOVIC
MANAF FAKHRO
EMMA WESTECOTT

For the last few months I’ve been working on getting this going with Nicholas Packwood. It’s fun to finally announce it to the world!

Submit your game now!
