      The benefit of traits vs. classes is that I can add *functions* to existing objects without needing to modify a monolithic definition. The benefit of ECS vs. structs is that I can add *data* to existing objects without needing to modify a monolithic definition.

      ECS is really interesting as a system architecture. But it's very much still in the "React in 2012 without contexts or hooks" phase -- lots of boilerplate and passing data around, at least in Rust/Bevy.

      may be worth perusing the new unity implementation in their new DOTS (data oriented tech stack) for another perspective

      That's cool! Didn't know about DOTS. I skimmed a few DOTS tutorials but didn't see anything addressing my main gripe: code modularity.

          Eg a helper function that computes what entity the player is looking at. It depends on global resources (physics engine, ray caster), but I don't want to make it a separate system. To call `player.looked_entity()` I have to pass through all its dependencies -- leaky abstraction.

          I think largely your gripes would still apply, just wanted to throw it out in case I missed something. Given the people leading that effort, they tend to eschew abstraction by default

          In theory, given they control the user experience, their could be facilities added that handle the boiler plate involved in some of those abstractions which require piping that data through

      Loading seems to be taking a while.

      Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
