# 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

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.
