programming games on roblox

@haizoopRBLX small lines per *feature* is good :). programmers can overabstract, your solution is probably simpler.
that said, don't watch the line count; write code as you need it, and factor into reusable functions if you repeat yourself. Readability should take care of itself

backend is Axum+Tokio, SQLite with custom pooling logic for WAL. Runs on a €24 Hetzner dedicated server with plenty of CPU to spare.

these figures shocked me! - but it's nothing on Roblox itself. It's a reminder of how well they handle these services for you.

built a Rust service to match and search trades across servers, in real-time! #RobloxDev

results filter "online" users. put together in a couple weeks to counter the new chat restrictions.

it's stayed responsive at peaks of ~25k players! no downtime. proud of this :)

@DecimalCubed the whole of wikipedia?? i promise you it's not going anywhere

@Fezezen i was prototyping an Alien Swarm-like game, which requires pinpoint accuracy onto the mouse. Doing this in third person was so horrible!!

@CheekyVisuals everyone I know has an Audio Technica. The cheapest is fine. Higher-end models have a speed slider, you can make your own slowed-lofi-beats-to-study-to :P

Wrote an open-source RNG game to demonstrate using Nevermore. I think it's a very powerful tool, I hope my example project encourages you to try it out!

thanks to @ecurtiss_ for help with the maths!
this community is great https://t.co/ySjYOOFzg8

stay strapped

@Fezezen I generated points a bit coarsely upfront for the geometry, then applied smoothing for the camera. But iirc, the algorithm only wants points i & i+1, so you can make it into an iterator

[OttoHatt @otto_hatt]

@Fezezen not merged, but a starting point perhaps? https://t.co/vcVpRAeQ4f. Sounds like a similar problem statement as implementing this... https://t.co/ePFKzvNUn8

Added rideable Pneumatic Tubes to my building game! Complete with sfx, particles, and a fancy camera. Stolen from Portal 2, of course ;)

@ComfyDayGames Yep, ImageLabels with UIGradients. Their Y positions increased by dt, modulo’d by tile height each frame. It’s not that accurate…! I’ll replace this when ViewportFrames get better rendering capabilities

[OttoHatt @otto_hatt]

Been making a lot of UI lately! Trying to nail a fun, yet neutral style that can be re-used across games. #RobloxDev

[OttoHatt @otto_hatt]

I put patterns on the interactable elements. Twitter video does not like it!

@CrossStarCross @beeni_online ‼️ https://t.co/v3RcN21vuP

The 400 boids in this video take ~8ms/frame (6ms of which is BulkMoveTo). Perf slows a bit over time; they tend to clump together, so the spatial hash grid becomes a less effective optimization. Possible big benefits from frustum culling (but then you'd have to disable shadows!)
