Is there such thing as a wait() function?

I have just joined, so I do not know if this is in the right area of the Forums. Sorry.

I have played a few other games where they have wait() functions and I was wondering if there was anything like that here.
I am trying to make a character jump when you hit the up arrow but I don't have a wait function, so I can't seem to work it.

A quick search for "lua sleep function" gives (from http://lua-users.org/wiki/SleepFunction):

Code: Select all

local clock = os.clock
function sleep(n)  -- seconds
  local t0 = clock()
  while clock() - t0 <= n do end
end
-- warning: clock can eventually wrap around for sufficiently large n
-- (whose value is platform dependent).  Even for n == 1, clock() - t0
-- might become negative on the second that clock wraps.

Note that this is a blocking function, meaning while you're waiting, you cannot do anything else - essentially, you're freezing the game for a while. If you want a non-blocking function, you need to integrate your code with the while loop somehow.

Somebody needs to tell the developers to add a wait() function....

There was a thread about this just last week: viewtopic.php?f=4&t=9345

@litearc: That's absolutely terrible. It's a busy loop, they are bad. At least mention love.timer.sleep.

But, as linked before, you don't want to pause execution.
