Short: C port of Ken Thompson's Space Travel Author: Ken Thompson, mohd.akram@outlook.com (Mohamed Akram) Uploader: polluks+aminet sdf lonestar org (Stefan Haubenthal) Type: game/misc Requires: SDL2 Architecture: ppc-morphos URL: https://en.wikipedia.org/wiki/Space_Travel_(video_game) # Space Travel This is a C port of Ken Thompson's [Space Travel](https://en.wikipedia.org/wiki/Space_Travel_(video_game)), ported from PDP-7 assembly. The original source files are in `src/cmd/st*.s` in the [pdp7-unix](https://github.com/DoctorWkt/pdp7-unix) repository. ## Install The SDL2 library is required. Run `make` to build `st`. Run `make install` to install to `/usr/local/bin`. ## Controls | Key | Action | |-----|--------------| | 1 | Quit | | 2 | New game | | 3 | Thrust down | | 4 | Thrust up | | 5 | Yaw right | | 6 | Yaw left | | 7 | Scale up | | 8 | Scale down | You can also use the arrow keys for yaw and scale. ## Gameplay > For controls, there were several buttons: jet forward, jet back, turn left, > turn right; go up scale on the display, go down scale. The acceleration of > the ship was fixed, but it scaled with the display scale--it was thus fixed > in terms of pixels/sec/sec. Normally the ship was in the center of the screen > and always pointed up; the display showed the plan view of the solar system, > so that the "rotate" controls rotated the solar system around you on the > display. > > No relativity; scale up enough and you travel to Pluto in a few seconds. But > don't scale up too much, or you might not find the Solar System again without > restarting. > > The object of the game was simply to fly around, get into orbits, land. > "Land" meant to cross the surface with a small enough speed. > > *[Space Travel: Exploring the solar system and the > PDP-7](https://www.bell-labs.com/usr/dmr/www/spacetravel.html) by Dennis > Ritchie* The current dominating attractor, scale, and landing status (L/CL for landed/crash landed) are displayed at the bottom. The moving dot on the line below the main view represents the horizontal velocity relative to the current dominating attractor.
