Show HN: I also made a three-body simulation

Somewhat inspired by a recent post here, I also made a three-body simulation on a whim, meaning to try out macroquad[0] (verdict: really nice!). Thanks to the engine I could trivially target wasm as well, so others can get mesmerized too.

I don't understand how the aliens weren't able to lie but they were able to falsify scientific results

that's like the third most common form of lying

Plot holes so numerous and large that it reminds me of all the other Sci-Fi works I have read. /s

So nice to look at, thank you for posting this, really cool

Would love to be able to zoom in/out and rotate, I kinda was expecting to be able to do it with the mouse and was a bit surprised that clicking just restarted the animation/simulation

Great work

Thank you.

The clicking to restart is there mainly for phone users, I realized after sharing with a friend that hotkeys aren't very mobile-friendly. I don't have a good way to detect desktop vs. mobile clients, and technically one can also have a keyboard connected to a phone.

I've also been thinking about zooming, I'll see what I can do over my next lunch break :D

Interesting choice of modular coordinates. I wonder how gravity works here. Does it reach across the edge or is it confined to the modulo?

UI is a bit unfriendly on mobile. It doesn’t seem there’s a way to interact with it on a phone.

I think this is very cool, but the edge warping negates a lot of the chaos imho. It keeps things interacting in the center of the screen, but it prevents the chaos of bodies being yeeted out into the void.

How was your experience working with WASM and implementing it on the page?
