Space Race is a small coding game. The objective is to implement a flight controller program which will allow a rocket to take off, orbit a planet, and then land again on the launchpad.
To play the game, you will need to create a solution.js file containing
a flight controller program, and then host it on a web server. By default, the
simulator will attempt to load the solution from localhost:8000/solution.js.
One quick way to get up and running is to use python3 -m http.server to serve
your solution.
If you want to load a solution from a different location, you can override the
loading path by setting localStorage.path via the developer tools in your
browser. For example, try pointing it at the template
solution to begin with.
< and > control time warp, like in Kerbal Space Program.? toggles the debug overlay, which will show you some of the important
effects which are normally not visible, such as satellite pings or air
resistance.To control the rocket, you will need to tell it what to do. The game will give you information about your rocket so that you can decide what to do. All communication between your flight controller and the game happens asynchronously: the rocket will not pause while you calculate a strategy, it will keep flying, so you need to act fast!
Communication in both directions is via the postMessage() API.
There are various kinds of message that can be sent or received. The full
interface is described in api.ts. In addition to
the raw API, there are some convenience definitions available for the flight
controller to use: see constants.ts and
math.ts.
There are multiple criteria by which you can grade your flight controller:
