Show HN: LightCycle, a FOSS game in Rust based on Tron

AnyTimeTraveler

This readme could really benefit from a screenshot.

Came here to say the exact same thing. At a glance, is it 3D or 2D? Console game like snake or with color and sprites? Etc.

Either screenshots or a gif would be nice.

Seems like Claude is not good at generating screenshots yet.

Fixes Applied:

  1. AI Self-Crashing Bug - Increased collision buffer zones and improved trail detection
  2. Linux Dependencies - Added comprehensive installation instructions for Debian/Ubuntu, Fedora, and Arch

  Improvements Made:

  - AI now skips 30 recent trail points (up from 10) to avoid self-collision
  - Increased look-ahead distances for all difficulty levels
  - Fixed trail collision detection in pathfinding
  - Added full Linux dependency documentation

  The AI should now survive much longer and provide a better challenge. And thank you for the two PR's!

Here's a recording of game play I made: https://imgur.com/Gy9mH57

Sorry if imgur sucks. I don't know a better option.

It was fun, on linux still had to install "sudo apt install libasound2-dev libudev-dev pkg-config build-essential"

Did some more fixes and then it was running. The game looks really fun but the AI player is always losing by himself too quickly.

Feels a bit more like Snake than Tron, but a very cool concept. Also quite impressed by the very readable 1000 lines of code. I've been writing a lot of Rust (various toy projects) for the past few years, but would love to do it for work at some point.

Gee, I'm sorry, but this is just over my head.

It takes over 282 crates to build this 1000 lines of code. It takes 1.3 gigs of space to display a window with a game on one's screen. And the AI does not work at all since it just crashes in itself. I'm not sure how this can be a good example of a program written in Rust. Rust is all about low-level optimized over-speedy small-sized binaries. Right now I see just a blob of something that barely works.

And yes, Light Cycle is in fact just a version of a Snake with a different ruleset.

This is cool! The code base is small to follow easily and also TIL ggez.

In the single player mode, the computer is not so intelligent. So initially i just kept winning without understanding what was happening.

They probably hate spending time debugging stupidly preventable errors.

nifty_beaks

They…didn’t want to?

Comment was not even sarcasm or joke. Just pure trolling. No need to respond to something like that in 2025.

nurettin

Looking at how clean the code is, that would probably be a 1-1 translation given you have the C version of ggez.
