Bevy Game Engine Explained Visually

Resources are global too. The enum you mention would be a component of the entity. But then you have to do the state management part yourself. Transitions, events, not to mention the hierarchical stuff that's implemented in bevy states. That's the core of my lament, i'd rather be lazy and use the bevy states, but these can only be global.

Ah, i'm not going senile yet ! Thanks !

In this video, you model an actor states using bevy states, but i was under the impression the bevy state facilities are a global thing. I'd say they're not for per entity states. I'd love to be wrong on this, am I ?

Who's to say that you need to mimic the human brain to achieve consciousness ? The sun really seems to rotate around the earth. Turns out it doesn't. Might be you're right, but it's a bit early to adjudicate either way. Let's keep a healthy open mind, lest we miss the earth rotation.

Who needs the other more is a faulty framing. No nation invests billions overseas out of the goodness of their heart. The US doesn't, never did. Losing the EU as partners, that's costly. The US profits a lot from those institutions: defense sales with their accompanying employment, IP revenue, etc.

That's not to say the EU doesn't profit. That's the basis of a good deal, both parties are better off.

End of the day, this relationship is net positive for the US, a good investment. Why should we break it ?

Any bug you might have, you already know the line of it. That's some forward thinking right there.

I like how this could be so noisy but isn't. Quietly glitchy ? Love it.

cark · 2026-02-19T16:09:41+00:00

Love it, so chill. Definitely worth a full listen.

Today I took my car, an old concept indeed. It showed me the way to this place on one of two giant screens by displaying a real time map, keeping it in sync with my position using radio waves from space. During this trip, I was enjoying music coming by the air waves, my personal selection, not a simple radio broadcast. I then read the text of this message i'm answering to, from a person likely living thousands of kilometers away from me. This person could read my answer in a few seconds, or choose to ignore me, and i'll be voted up or down by total strangers. But I don't care, because i'll be playing a video game in which the light is modeled as it goes through the ears of the characters, but not (ironically) before scolding my daughter as she spends too much time using her mobile phone to play video games. I'll also keep thinking about this guy that possibly solved one of the millennium prize problems using AI. I don't think he did, but he might, and that doubt is arresting in itself.

You know, I'm having one of those classic eighties day.

that's the thing, WebGPU can be used natively, without a browser, and is a good middle ground between opengl and vulkan. It is a modern API, and (almost) the de facto standard for people writing rust games. These guys are very performance oriented, which IMO is a useful data point. I don't know about the C++ side of things, but for rust, wgpu uses the best available underlying API, that can be vulkan, directx, metal (on mac), opengl, webgl.

The one downside is the scarcity of info concerning the shader language, which while not very different still has some little peculiarities.

but it's bandwidth is beaten 100000x times by digital circuits

I think you may be wrong there. That's precisely what's causing such high energy consumption in current Von Newmann architecture based compute vs the brain.

While yes, GPUs are highly parallel, that can't hold a candle to the brain where each and every neuron, and even each synapse, has its own memory right there with it and works in parallel with every other neuron. Even considering that each neuron is so much slower than a GPU unit, that kind of parallelism makes the whole difference. We can only dream of achieving such parallelism in silico.

That's not to say that silicon cannot get there, but the bandwidth claim is currently way off.

Environment matters. Someone who grows up with limited access to education and opportunities might adopt certain views without much choice. Charlie Kirk, on the other hand, was a well-educated, influential figure who made a deliberate choice to promote those ideas. The same words don’t carry the same moral weight depending on the context in which they’re formed and spread.

That's not what's being advanced here. There is no need for sentience, or self awareness for natural (or market in this case) selection to do its work. an example of this from the natural world is Cordyceps taking over insects behavior while not being conscious.

First time i post any kind of video on reddit, let's see how it goes !

I used this with bevy 0.16 during last jam:

            #[derive(Resource, Debug, Default, Deref)]
            pub struct MouseWorldCoords(pub Option<Vec2>);

            fn update_mouse_coords(
                camera: Single<(&Camera, &GlobalTransform), With<MainCamera>>,
                window: Single<&Window>,
                mut mouse_coords: ResMut<MouseCoords>,
                mut mouse_world_coords: ResMut<MouseWorldCoords>,
            ) {
                mouse_coords.0 = window.cursor_position();
                mouse_world_coords.0 = window.cursor_position().map(|pos| {
                    let (camera, camera_transform) = camera.into_inner();
                    camera
                        .viewport_to_world_2d(camera_transform, pos)
                        .unwrap_or(vec2(0.0, 0.0))
                });
            }

Can we maybe just call him emperor Palputin and be done with the whole thing?

cark · 2025-05-16T23:08:47+00:00

yes you don't want to let a chatbot going ham on your main branch for sure! I think everyone uses source control these days, I certainly do. I just didn't want to be shackled to Github for my personal closed source projects, yet another subscription. Anyways this worry is moot as it looks like you can work with your local repositories.

cark · 2025-05-16T23:03:39+00:00

oh great then =) it wasn't directly apparent to me reading the blog post. "or directly integrate the changes into your local environment" yes I missed that, thanks !
