Variations on Rockdodger

VoR is an exciting Free Software video game, licensed under the GNU GPL. It runs on GNU Linux, Windows and AmigaOS4.

"it's fast-paced, difficult and addictive." -- Linux Format

VoR is a simple, fast-paced action game that will challenge your reflexes. It has excellent gameplay, great physics, good graphics, and a retro/synthoid thumpy beat to help put you in the mood for old-school 2D gaming.


VoR is very stable, well polished and loads of fun! Jason Woofenden is working on getting it into the major GNU/Linux distros (Ubuntu, Fedora, Debian, and OpenSUSE).

We have not been adding new features lately (2010), however, we will certainly work to fix any bugs or compatibility issues if they are discovered.


A shower of sparks is starting to shoot from the right thruster as the pilot tries to lose a little momentum.

Here's a video of VoR in action: http://www.youtube.com/watch?v=Hdrmm3ef040

Help out!

Please help us by making VoR easily available on other operating systems!

In particular we'd love to get someone technical make a Mac binary. The source code compiles fine on Mac. The work is mainly collecting the libraries and creating a bundle. Please contact Jason Woofenden about getting transparency to work.

If your platform supports a larger icon than provided, you can use this 128x128 one: http://jasonwoof.com/downloads/vormacicon.png

Please contact Jason Woofenden with any questions or binaries.


VoR requires the following to build and/or run:

Libraries: SDL, SDL_mixer and SDL_image (which requries libpng and zlib)

Software (used to build): gcc, make.

If you want to change the graphics or work from the repository, you'll also need: povray, netpbm. (On some distribution(s) the necessary part of netpbm is in the package "netpbm-progs".)


This is a fairly hard game, intended to be a quickie game for when you want to kill a few spare minutes. For reference, my best time [Josh Grams] is about 2 minutes in version 0.3. I'm not generally very good at video games, but I have been playing this one for quite a while now. However, as of version 0.4, there is an easier mode (press '1' for an easy game).

The most important thing is to tap the keys very gently! Overcontrolling is the leading cause of death among new rockdodgers!

As an exercise, try using only the shortest taps you can manage. On the easier difficulty setting, it's usually possible to reach 30 seconds with 15 (or less!) very brief pulses of the jets. It's often good to kill your speed with a pulse on the opposite jet once you're clear of the rock you were avoiding.


Jason Woofenden and Josh Grams like rockdodger very much: both playing it and hacking on it. VoR is the result. They forked from rockdodger 0.4.2 in the summer of 2004, and over the next few years rewrote or refactored most of the codebase. The premise is still the same: dodge the rocks until you die; almost everything else has been modified in some way or another.
