[Question] Timer

Hi, I probably already know this but I forgot, but what is the code to use a timer, I'm pretty sure that the os API has one, but there might be others, I'm not sure…

Just use:

os.startTimer(time)

and then wait for a "timer" event.

A quick look at the wiki would have answered this.

Thanks, I had already looked on the wiki, but I couldn't find it for the life of me xD

I just checked the wiki and it says that it makes a table to show when its done, I don't really know anything about tables, could I have an example of the code that detects when the timer is over? Or can I use a os.pullEvent?

The table is just used as an identifier for the timer, you don't need to use it. Just wait for a "timer" event (using os.pullEvent) and then check if the argument of the event equals the table returned by os.startTimer.
Example:

local timer = os.startTimer(5) -- start a timer for 5 seconds
while true do
  local evt, arg = os.pullEvent("timer") -- wait for a timer event
  if arg == timer then -- check if the timer fired is the one started before
    print("Time's up!")
    break
  end
end

Ok, thanks for the help!
