Moon simulator game, ray-casting
Technical Positioning
A personal project, 'seems apropos.'
SaaS Insight & Market Implications
This submission presents a personal project, a moon simulator game utilizing ray-casting. It lacks any discernible B2B SaaS application or market positioning. The project's nature as a recreational or educational endeavor means it does not address enterprise pain points, nor does it indicate trends relevant to B2B software development, data management, or operational efficiency. Consequently, there are no direct market implications or B2B opportunities to analyze from this submission. It stands as a technical demonstration without commercial intent or strategic value in the B2B SaaS landscape.

Show HN: Moon simulator game, ray-casting
Did this a few years ago. Seems apropos. Sources and more here: github.com/EngineersNeedArt/...
Developer Debate & Comments
Cool game. The sound keeps glitching on and off. Also, maybe I'm just dumb, but I couldn't figure out where to go or how to land.
Game is broken with adblock btw (UBO)
Awesome to see this on the front page! Ever since you posted it on HN Arcade its been one of my top games :) and its also one of the most visited!
Why can I just go 30? Feelsslowman
Very slow on Firefox (both wrt frame rate and actual game speed) and gets down to single digits FPS after a while.But the slow speed and weak acceleration (did you forget that v = v + a*dt and not just v = v + a? :)) feels actually nice and meditative, if only the FPS were smoother. Tried it on Chrome and it's a much more dynamic and fast-paced experience on it.(Edit: took a look at the README, loved it!)
I love this gorgeous and evocative little time waster and come back to it every now and then. Notes:It starts out buttery smooth but over time its performance slows to a crawl. Changing window geometry seems to do some sort of garbage collection and it speeds back up. I just hit F11 twice real quick.The optimal strategy is to try and make the trip parabolically with a single large burn at liftoff.Gravity physics is of course symmetrical on ascent and descent, so the optimum time to start your deceleration burn is approximately when your downward velocity is equal to whatever your upward velocity was when you stopped burning.
Hey I really liked this. Reminded me a tiny bit of Lander on the Archimedes, Hardwar (underrated!), Wing Commander-y visuals.The extensions suggest themselves - some progression (financial) beyond merely guild hierarchy; some adversarial element (could be economical like bidding for routes.)Only bit I struggled with was the car-like handling when you turn left and right; I would expect you to orient using yaw axis and then have to use thrust to change your velocity vector. But it certainly is simpler the way you have it.
Why can't accelerate to my hearts content?! We're trying to get in to orbit here!
The README is phenomenal, it really tells the story of how the game was built.
Very neat. Reminded me a bit of Terminal Velocity from a purely visual perspective (even though they used a more standard texture mapped 3d engine).https://en.wikipedia.org/wiki/Terminal_Velocity_(video_game)
