📖 Tray & Error Handbook

Program your robot waiter to seat, take orders, and deliver meals before customers complain.

1. Seating & Queues

waiting_parties() returns guests at the entrance. free_tables() returns empty tables. Match small groups (1-2) to small tables, larger (3-4) to long tables.

seat(party, table)

2. Orders & Kitchen

Seated guests take 3s to decide. take_order(table) retrieves their order (including special notes like "no onions"). The chef must call handle_note(ticket) before plating. Send it to the chef with:

send_to_kitchen(order)

3. Tray & Delivery

Cooked meals appear in ready_dishes(). Lock a dish with claim(dish), then serve it with deliver(dish, table). Check tray() for carried meals.

4. Robot Upkeep

Check battery(). When low, call go_charge(). Check is_night() to handle midnight menus & night owls! Use health() and repair() for wear.

5. Firmware (Shop Unlocks)

nearest_table(status) returns the closest table. order_stock(qty) buys stock for $2 per portion. Locked calls log a warning and return None / False.

📖 Tray & Error Handbook

1. Terminal Basics

Loops & Waiting

Scripts repeat with while True:. Indent the body by 4 spaces. Add wait(1) so the loop does not spin. A runaway loop is stopped by the watchdog.

while True:
    wait(1)

Errors & Storage

Errors appear in the terminal with a line number. Each terminal has a line budget; blanks and # comments are free. Buy RAM Expansion in the Shop for +15 lines.

Breakpoints & Watch

Click a line number in the gutter to drop a red breakpoint. The script pauses there. The Watch panel shows local variables plus battery, health and tray. Collapse it with ◂; Step runs one line at a time.

2. Waiter Robot

Seating

waiting_parties() lists guests at the door. free_tables() lists empty tables. Match party size to seats, then:

seat(party, table)

Orders & Delivery

take_order(table) after 3s. Send it with send_to_kitchen(order). Take plated dishes from ready_dishes(), lock one with claim(dish), then deliver(dish, table).

Reservations

A table with a tent-card badge is booked. free_tables() skips it and is_reserved(table) returns True. Seat the booked party first: a walk-in at that table loses both parties and 0.6 reputation.

Upkeep

Watch battery() and call go_charge() before it hits zero. Moving wears the robot down; check health() and call repair() at the charger ($15 day / $5 night) when it drops below 20%, or movement slows by 40%.

if health() < 20:
    repair()

3. Chef & Special Requests

Cooking

Read tickets with tickets(), take ingredients with grab("ingredients", 1), cook, then plate(ticket).

Notes Are Mandatory

A ticket may carry a note such as "no onions". Call handle_note(ticket) before plating. If you ignore it, the customer complains and the tip is lost.

handle_note(ticket)
cook(4)
plate(ticket)

4. Firmware & Fleet

Firmware Commands

nearest_table(status) finds the closest "free", "order" or "served" table. order_stock(qty) buys stock for $2 per portion. Both are locked until bought in the Shop.

Two Waiters

Both waiters share the counter. claim(dish) returns True for exactly one robot, so two scripts never grab the same plate.

5. Tutorial Reference

Seating & Orders

waiting_parties(), free_tables(), seat(), take_order(), send_to_kitchen(). Match party size to seats and keep the queue moving.

Serving

ready_dishes(), claim(), deliver(). Claim before carrying; deliver to the table on the dish.

Upkeep

battery() / go_charge() and health() / repair(). Charge at (1, 0); repairs cost $15 by day, $5 at night.

Time, Money & Fleet

is_night() switches the menu. Rent is charged daily. The Shop sells upgrades and firmware. Waiter #2 shares the counter, so always claim() first.
