Earlier quoted context omitted.

I wish there were more games like this. It’s such a simple premise but so satisfyingly difficult after each level. And it even has a bit of randomish failure which makes for even more challenge.

I had the idea to build something like it but for traffic lights. Never got around to actually do it. I have a feeling it probably exists.

same :) Although, I wonder if building it is more fun than actually playing it then

I am currently staying in an AirBnB of a 60 floor tower, and the three elevator shafts definitely cannot handle this (I don't think the building was designed with renting to tourists in mind). The elevators are frequently completely saturated during weekends, meaning that the elevator stops at each floor, but noone can get in because the elevator is already full. This means the backlog of people wanting to use the el…

A 60 floor Airbnb tower? 2026 is wild.

I don't understand why the fact that it's an Airbnb really matters here? Unless a large number of apartments are meant to be empty, why does it matter if the tenant is short term or long term? Is it that short term users leave and enter their apartment more often?

This is pretty cool. OP+author, I wish that it was possible to gray out the elevators as the speed increases, so that their high-contrast "flashing" is reduced while still allowing their movement patterns to emerge. You could even go as far as to fade their color back in once they're standing still, so that the 'stop' locations in the LOOK vs RSR diagram become really clearly apparent, while the elevators' non-stop movement fades into the woodwork as orange dots travel endlessly in the left.

I figure something like a simple weighted ratio of car color = { 1.0: car fg color, max(1,speed^0.1)-1: shaft bg color } would do, so that 2x only shifts the color 7% towards the background color, but 500x shifts the color 86% towards the background color — and a stationary elevator can fade in from 86% bgcolor to 0% bgcolor over a few ticks as it sits there.

I recognize that for most of us, the flashing elevators blur into motion blur, but I can see individual frames at 120fps and while I am not seizure-sensitive to high-contrast flashing, I imagine those folks would appreciate you going the extra mile to reduce contrast at higher velocities, too.

ICE Condominiums Tower I, Toronto?[1]

Elevator load measurement is an option you can buy.[2] Somebody didn't. 60 stories with three elevators is underserved, and needs all the control help it can get.

> Destination Dispatch [...] are in general worse I wonder if this is an artifact of how the author used random destinations. I worked in a building that used Destination Dispatch, and the common travel pattern seemed to be: - Everyone who is not on the ground floor generally want to go to the ground floor. - People who are on the ground floor generally travel in large groups to the same destination. This happens bec…

Yeah, and definitely is not the right story for hotels. His premise of "morning traffic mostly from lobby to floors" is completely false in an hotel where you get it both ways due to people going down for breakfast and going back up and the down once again. I see hotels with the kiosk model changing the UI depending on breakfast rush hour

> Yeah, and definitely is not the right story for hotels.

The first time I encountered Destination Dispatch was in a London hotel, maybe 15 years ago. Anyone unfamiliar with the system would naturally sprint towards an open elevator and end up in an elevator with no buttons, totally bewildered. It's not the right system for a transient population.

Because they are short-term and many are staying just for the day + bringing family (like kids, which is why they use AirBNB instead of a hotel). The check-in/check-out already add an entry-exit if the user is staying 24 hours only.

Or, the building / owners corp / code / city could simply ban short stay accommodation where it was never attended. I would not want to be in that building if an evacuation alarm sounded.

> I would not want to be in that building if an evacuation alarm sounded.

why short term/long term stay would matter here?
