The whole idea behind dumb client/simulation server was to be able to support cities too big to be simulated on one machine (the simulation server can be distributed). I already have quite sophisticated streaming logic that basically m

I appreciate the sentiment and always suspected as much about SimCity. My goal for Citybound is really a meta one: to be flexible enough to try out any number of government and planning styles and for the simulation to be tweakable enough t

You're right. I want to switch to TypeScript in the front end, I use it in most other projects where I can. What would be amazing is if I could generate TypeScript defs from Rust types for type safe interop.

I'd love to know. AFAIK all builds include debug info, so it can't be that.

I would love and very much want such things to be possible - and to still make it an obvious reaction to your player decision.

Yes, I also have a lane changing model. What exactly would you like to see in a writeup? And which teaching setting do you have in mind?

It's just crossed out because I didn't write anything about my plans yet in the design document. I do want to have a weather and water simulation at some point.

It's a spectrum. My goal is to "teach the right things" that you would need in a realistic setting and have the simulation try it's honest best to simulate everything in realistic scope, detail and behaviour, but I might

Thank you so much for becoming a Patron! Citybound's architecture is highly unusual with its distributed simulation backend and browser rendering frontend, so I'm not sure how good it is as a reference. It's also almost not d

I build a simulation engine, based on a high performance distributed actor system library I wrote for just this purpose. It is generic, but a lot of the performance trade-offs are with Citybound's needs as the main driver.

This works well if you only care about the class of destination. In Citybound, people have unique, persistent homes, jobs and favourite suppliers of goods, so you always need point-to-point routing. I'm using a kind of internet-like dy

It actually worked out way better than I expected. With a bit of memoization using references to immutable objects and some "hotness" grouping mechanisms for renderables that change frequently, but not every frame, you get a purel

There's a lot of interesting stuff going on in there. First, for the curves itself, it does a kind of naive approximation optimisation and builds a curve out of line and arc segments that tries to follow the control points as closely a

Hopefully soon I'll have a sandbox server hosted somewhere!

I didn't really ship it yet (got posted here by someone else), it's in continuous development for already ~5 years.

I didn't play it enough (yet) to feel comfortable putting it there, compared to the other things I listed as inspiration. I feel like it deserves a more in-depth comment/comparison. I've only watched let's plays of it so

Transit, pedestrians and later bikes will be the next features I want to work on regarding transportation, after I make all aspects of the simulation scale to larger-than-rural settings with car traffic.

I assume you talk in terms of what constitutes an actor in the actor system: because cars on one strip of road interact highly locally, so processing them in one batch makes a lot of sense performance wise, vs. every car sending messages to

Exactly. And I do use Rust compiled to WebAssembly to do lots of the "render preparation" work (converting streamed simulation states into render buffers), which makes it pretty fast.

I had a nice comparison because I first tried to do a native implementation in C++ and - wanting to do some custom low-level "stuff" for my simulation actor system (related to allocation and networking) - I ran into so many footgu

Appearances will be increasingly important to Citybound, I’m going for a flat shaded but super detailed look. Thanks for becoming a patron, much appreciated!

Author of Citybound here! Feel free to ask me any questions about the project! I’m mostly active on the Citybound subreddit in general. Also, check out the main homepage at https://aeplay.org/citybound for a more player-cen

Author here, thanks for letting me know, I’ll test the font on more devices and fix it!

Hi, blogger's new "dynamic views" template that I'm using seems to be powered by js exclusively. Sorry about the inconvenience.

thanks! I'm still a student so I try to use my luxury of free time as good as possible.
