 Event timer | |
| Fired when a timer completes. | |
| Returned Object 1 | The timer's unique ID value (returned when os.startTimer(), which triggers this event, is called). |
 Example | |
| This code will loop and refresh every 1 second. If the event that occurred was a not a timer (eg a key event from a keypress), the loop will complete. | |
| Code |
while true do
os.startTimer(1)
local event = os.pullEvent()
if event == "timer" then
print("Too slow!")
else
print("You've beaten me!")
break
end
end
|
| Example | |
| This code will output different text depending on which timer has completed. | |
| Code |
local timerA = os.startTimer(1)
local timerB = os.startTimer(2)
while true do
local event, completed = os.pullEvent()
if event == "timer" then
if completed == timerA then
print("TimerA has finished, restarting it now")
timerA = os.startTimer(1)
elseif completed == timerB then
print("TimerB has finished, restarting it now")
timerB = os.startTimer(2)
else
print("A timer finished, but it wasn't one of the ones I care about")
end
end
end
