Control Flow

yield()

Pauses the script until the next game tick. Use in a loop to run code once per tick:

while true do
    local temp = ic.read(0, ic.enums.LogicType.Temperature)
    print("Temp: " .. tostring(temp))
    yield()
end

sleep(seconds)

Pauses the script for a real-time duration. The runtime counts down across ticks:

print("Starting...")
sleep(5)
print("5 seconds later!")

tick(dt)

If you define a global function named tick, it's called automatically every game tick:

function tick(dt)
    -- dt = seconds since last tick (~0.5s typically)
    print("Delta: " .. dt)
end

throw(message)

Immediately throws a Lua runtime error:

throw("something went terribly wrong")

hcf()

Halt and Catch Fire — permanently destroys the chip:

hcf()  -- The chip is gone. No undo!

DANGER

hcf() is destructive and irreversible. The chip item is permanently destroyed. Use with caution (or for dramatic effect).
