Let a door open for arrivals, stay open for a whole queue, and close after the last

A door that opens and closes for every single person makes a busy barracks look like a nervous machine, and a door that closes on someone standing in the doorway cuts them in half. This entry gives a door with a delay before closing and a rule about who may pass and when, so queues flow and nobody is caught.

Why this works

A door is there for people, so it should react to what people need: open when someone is coming, stay while someone is in it, and close only after a short pause. That pause is what stops it flapping between two people who follow each other.

When not to use it

Wrong for doors the player is meant to control, such as locked gates, a drawbridge or a vault that opens only with a key or a lever. There the door follows the player's choice, not the traffic.
