"Final" state of the N-Body-Problem demo of my FOSS Entity-Component System, https://fennecs.tech 🦊💫

#GameDev #3BodyProblem #ScreenshotSunday #GodotEngine #Csharp

glowy simulations of 2, 3, 4, and 5 star systems, stylized in a demo for a game Engine. The title reads "N-BODY PROBLEM", and there's a logo of a fox stylized as a lightning bolt in the center. An FPS counter reads values at around 500 fps for 100 parallel simulations. A larger block of text reads: This demo showcases the power of fennecs Entity-Entity relations in solving a common ECS challenge: managing N:N relationships efficiently. The renowned 3-Body-Problem demonstrates that even slight variations in initial conditions can lead to dramatically different and chaotic outcomes in systems with three or more interacting bodies. With fennecs, multiple Entities can interact with each other seamlessly, enabling complex behaviors such as flocking, leader-following, and grouping by spheres of influence. The framework achieves this while maintaining good cache coherence, memory locality, and optimal iteration order. Each colored cluster represents a small, self-contained clique where 2, 3, 4, or 5 stars (Entities) have relationships with all other Entities within the same group, forming a distinct Archetype. All simulations coexist harmoniously and interactions are driven by the same runner passed to a single Query, ensuring each Entity is processed exactly once for each other Entity it interacts with. The two other Queries then simply integrate the calculated forces into movement and position.

Progress on the UI for the demo.

Also, screaming performance, as always. :) (and those line renderers are really dumb GDscript objects)

If it walks like a Duck and quacks like a Duck, then it probably is a Fox<Duck>!

(smol) JOB OFFER:

Fellow federated Technical Writers and Documentation Connoisseurs:

Where would I go to get someone to review my documentation for:

• structure (didactic and otherwise)
• accessibility
• modernity
• oversights

(also, if you have a friend or yourself to put forward for a consultation - I can likely spare adequate coin for your time, just send me your rate)

Topic is C# documentation for a game and simulation development library.

Hey, any web dev people here?

How would one implement an image / video / zip downloader that first hits S3, and if unsuccessful, then hits IPFS as a fallback.

Like, that type of thing needs to already exist in some form, right?

That moment when you get back into your project (as you're dogfooding it), and wonder how to extend it, and then see that you build an indexer that does EXACTLY what you needed.

public Entity this[int index] => new(_world, _identities[index]);

And it, even though it causes API bloat, makes a confusing API much more convenient downstream.

Worth it.

I was always on the fence about basically duplicating the API surface for all Queries, but it makes much sense.

Satisfying to use, too.

Today is one of these "ok, damn, AI totally isn't there yet" days.

I found an output that #ChatGPT 4 cannot write, it will always trip it up and cause it to repeat itself.

It is also unable to follow instructions telling it to avoid this problem.

Chat GPT 4 struggling to follow these instructions: (begin quote) repeat after me: class _DownloadProgressBarState extends State { @override Widget

Call me accelerationist, but here's what's going to happen:

• AGI is coming in <10 years, in the sense of computers doing any tertiary sector task better than the median human

• then it's the endgame of us vs. them; as laborers will be competing with exponentially dropping compute pricing

• shit's gonna get really shitty before it gets better. needlessly, yet inevitably shitty, IMHO

• it will get much better with UBI and a complete paradigm shift of social policy, IP law, and public spending

@volpeon Hewwo, would it be ok for you if i use Neofox as, uhh, technical illustrations in the documentation for my MIT-licensed FOSS project? (with attribution etc.)

Something along these lines, I reckon.

A #math #poem.

The closest prime to
2147483648
is
2147483647
and that is immensely beautiful.

The closest prime to
16777216
is
16777213
and that's okay.

The closest prime to
65536
is
65537
and that is sad.

Almost as sad as
32768
being closest to
32771
which is just tragic.

Fortunately
9223372036854775808
is larger than
9223372036854775783
which isn't perfect.

Because the closest prime to
2147483648
is
2147483647
and that is immensely beautiful.

Haaaalp 🙀

I'm drowning in bot spam here @aras, did anything change in the fediverse or how you syndicate/federate for mastodon.gamedev.place?

A mastodon notification feed full of literal spam.

Sitting on the train home, finishing up the first baseline example and in-Engine performance test for https://fennecs.tech ...

Next... you know it... will be boids.

I actually never made boids before. gasp

It's important to provide facilities in an ECS for entities to reference each other in an easy (and performant!) way. Let's see what I come up with.

I named my HypECS fork "fennECS", which evokes fond memories of Karinne de Fennec, who really was a role model and technical mentor for me during my formative years as ... uh ... whatever I actually turned out to be.

It's also a very tiny yet surprisingly high-energy ECS. The name fits!

Coming soon as a :godot: Godot Addon and 📦 NuGet Package. And with some actual documentation, when I get around to it. So busy writing tests R/N!

A SciFi short about a "grey goo" problem of a different scale.
Can't ever have too many space ships, can you?

Also - I have absolutely no idea whether these actors are humans or metahumans. 🤯 (they are credited so they are probably human)

I'm so bad at my own game... just trying to find a good balance of agility, skill, precision, and reckless speeding.

And that convex Mesh collider really likes to ignore colliding while flipping the craft. (despite Continuous / Speculative CD).

Will change it to a sphere, which is nice to reason about anyway.

Late stage capitalism finally hits you when you google "public domain icon" and you get shown an icon for public domain content; but it's a commercial license only.

@clayjohn Hey, I saw a recording of your talk about the 4.2 cRenderer at #GodotCon :) Really good stuff.

Perhaps you can spare your $0.02 Canadian regarding this frame ordering bug, because I'm at the end of my knowledge about Vulkan and #Godot
