37:20 - This needs a proper explanation. You have an array of structs and you set them as numbers? What? Seriously I think you should have spent more time explaining the link between entities components and systems in a simple manner so we can link them with equivalents in our languages. Don't just show code explain code.

Underrated talk. How do you manage complex states with ECS? Like how do you involve statecharts with ECS? Is there like another system that observes each entity and is responsible or adding for removing components from entities and/or using a different system entirely for certain entities in certain modes?

in web development, we call this Model View Controller or Presentation Abstraction Controller

I think the twitter question about no chains is probably because the systems functions are not pure (mutation of a component that came as a parameter). So while some of ECS aberration of hierarchies and data and code separation sounds like functional it doesn't really seem to care about function purity or even first class functions to be able to work.

What are ECS in a nutshell: They are in memory datastructures of normalized relational database systems. It's as simple as this and only gets a new paradigma if you poisoned your brain with object oriented progrmaming too much.

Several simulation systems use ECS like (in fact Data Driven Design), as many raycasting engines. A lot of AI stuff also uses it in a certain level of the architecture (before semantic mappings)

What a fantastic team. I've listened to a lot of ecs and dod talks, but this is one of the few to make me laugh

TIL Tasmanians say "cache" funny

Thank you for this. Great information. Currently considering the applicability of ECS and game engines in my small corner of the simulation industry. This helped a lot.

Are the slides available?

Really great talk

She had an awesome shirt! 👍

Awesome talk

This is worth the watch. IDK why a good talk on ESC seems so hard to find.

That question about unity being object oriented because c# is oo irks me. No language is object oriented, the programming is. A language can support oop, but that doesn't make the language itself oo. In c# you can use simple classes, static methods and as many globals as you want, avoiding every aspect of oop and it would totally work. In that sense thinking the language limits you into programming that way is also wrong. Everyone starting off with programming will have started another way than object oriented, likely with a so called object oriented language.

i searched for hey jarvis find images of red objects that are fairly round with white in the middle then caption it ''amogus''

Can an entity be made up of other entities? I find it hard to apply ECS outside of game software. Like in gui domain of a generic app, you can have the properties of a model be either a text box or drop down. To me the entity is the model and its properties are more like other entities than components. If they were components you would end up with the same component multiple times which is awkward. None of the talks on ECS really cover this type of a problem. Any thoughts on this?

Awesome talk, seems like a good fit for software architecture conference, games are software after all. Really enjoyed this and good humor not forced

I found this video randomly through the "Welcome to WesterosCraft" talk and I just wanted to say: Awesome talk! :)

I come from video games, now work at a watch company. I build design tools for them and use ECS. Interesting talk.

Enjoyed the presentation. As a fan of ECS architecture, I can tell that y'all had to gloss over a lot of details to tackle this topic in such a short amount of time. I for one applaud the effort. BTW, that outfit just screams Star Fleet...would make for awesome cosplay.

enjoyed your presentation. thx

really interesting to see how communities like these grow almost organically like order from chaos. I made a video walking around this server around Casterly Rock and I'm thinking about using the server in my lessons sometime (I'm a history teacher). Adding shaders was kind of difficult and I had to purchase minecraft just for this server but it was worth it honestly. Once you turn your FOV up a notch it becomes a really enjoyable experience to explore indoors

Awesome stuff marsypan!!!!

Wait wait wait. Hello attackonmars
