The self-checkout and its rules

The self-checkout is an automated checkout with a check for whether it can be used.

The self-service till in Supermarket Simulator is a machine with conditions: the game checks whether it can be used, tracks whether a customer wants help, and switches its detail by distance.

In play

The self-service till is not only a smaller version of a normal one. It has conditions of its own, and the game checks them rather than leaving the machine to fail quietly.

There is a check for whether it can be used at all. That check is what stops a self-checkout from being treated like an ordinary lane when something about it or the customer makes that impossible.

It also knows whether a customer wants help. That is a separate question from whether the machine works, and the two are tracked apart, which is why a self-checkout can be working and still need a hand.

The game keeps track of whether a customer is at the till. Knowing that a customer is present is what lets the rest of the checkout decide what to do rather than reacting to a machine with no one in front of it.

Its detail is switched by distance. There is a renderer whose job is to decide how much of the machine to draw, so a shop with several self-checkouts can show them all without drawing every one at full detail.

It is still a checkout like any other. A checkout carries a type, and the automated machine is one of those types rather than a system apart, which is why the same code can run a staffed lane and a self-service one.

The barcode side is shared. The scanning documented elsewhere applies here too, so what differs is the rules around the machine rather than the act of scanning.

The image beside this entry is the game's own: the self-service machine itself, with its two screens, its scanner bed and the bagging area beside it.

What this entry does not tell you: how many self-checkouts you may have, what makes one unusable, or how often customers ask for help. We have not verified those, so we do not print them.
