Judging by the system & component names this looks to be pretty well designed tbh. There are a lot of systems for sure, but considering this is a city simulator that's kind of expe…

> I bet the current design passes and queries data all over the place, very redundantly That's not how ECS works. A system has one or more queries that provide it direct access to …

The query engine works on top of an Entity Component System (ECS) storage that stores entities and their data in cache coherent (SoA - https://en.wikipedia.org/wiki/AoS_and_SoA ) d…

Or if you want code that's easier to extend, read and don't want to do your own memory management. Here's a bit of code from that project that generates a monster: https://github.c…

The same goes for Flecs: - it has tools like https://github.com/flecs-hub/explorer that work with any Flecs project - it has builtin support for hierarchies/prefabs and more ( http…

The way you frame the question already suggests a solution, and one that indeed doesn't fit ECS that well. That doesn't mean you couldn't design a DAW using ECS, but you'd have to …

> but still ECS incurs massive overhead compared to basic arrays of structs I actually know of quite a few projects that use ECS as the foundation for a low level rendering library…

The opposite also applies: don't reinvent the wheel if you want to get something done. Existing game engines like Unity/Unreal already have builtin solutions for entity management,…

I'm definitely not going to argue that you need ECS to do much of anything, but ECS has come long way in the past 4 years from a tool that lets you have lots of entities in a game,…

It could be yep. One of the things that makes it a good fit for this use case is that Flecs has a query language that supports things like graph traversal and joins. Combined with …

Definitely possible. I know of a project that used an event-based architecture to decide when to run ECS systems.

The biggest reason for me was to reduce compile times, which got cut into approximately half when I replaced STL containers with simpler custom ones. This starts adding up in large…

Pretty close, but there's a bit more to it. This post goes over one way an ECS can store data: https://ajmmertens.medium.com/building-an-ecs-2-archetypes-a...

Whether ECS is complex or not depends a lot on which one you use. I've heard the same thing from a lot of gamedevs that use DOTS, but people in general seem to be pretty happy usin…
