Lua Reascript Is there a "wait ()" statement equivalent?

[Thonex]

I'm coding some mixer toggle states and would like to minimize clicking by ducking volume and then waiting and then resuming functions.

Is there a Reascript or Lua command that would be equivalent to a simple wait(ms/Ms) command?

Thanks.

Cheers,

os.sleep, but that will cause Reaper to wait as well.

You can use defer to let a function keep checking the time and then do something if time_now - time_started > X.

local function Msg(str)
   reaper.ShowConsoleMsg(tostring(str) .. "\n")
end

time_start = reaper.time_precise()
Msg("Starting a timer for 2 seconds...")

local function Main()

    local elapsed = reaper.time_precise() - time_start

    if elapsed >= 3 then
        Msg("2 seconds have elapsed! Ending the loop.")
        return
    else
        reaper.defer(Main)
    end
    
end

Main()

Thanks Loka!! Again!!

Will try it out this weekend.

Here's to hoping it will give milli or micro second precision.

Sorry to say, but it won't. The deferred functions are called about in the 30-50 millisecond range without any guarantees. (If anything in the GUI thread stalls due to Reaper's operations or 3rd party plugins, the ReaScript deferred functions will also stall.)

Ok, I am trying to make a Wait() function to work inside other defered function. Mostly for debugging . And controlling the rate of prints.

function Msg(str)
    reaper.ShowConsoleMsg(tostring(str) .. "\n")
end
 

function Wait(time_start, delay)
    Msg("func timestart    "..time_start)
    elapsed = reaper.time_precise() - time_start

    if elapsed >= delay then
        Msg("2 seconds have elapsed! Ending the loop.")
        return
    else
        reaper.defer(Wait)
    end
end
 
function def()
    local mainHandle = reaper.GetMainHwnd()
    local focusedWindow = reaper.JS_Window_GetFocus()
    if reaper.JS_Window_GetParent(focusedWindow) == mainHandle then
      reaper.ShowConsoleMsg("aloha".."\n")
    end
    
    Msg('mainHandle       '..tostring(mainHandle))
    Msg('focusedWindow       '..tostring(focusedWindow))
    Msg('reaper.time_precise()       '..tostring(reaper.time_precise()))
    Wait(reaper.time_precise(), 2 )
    reaper.defer(def)
end

def()

I tried to adapt lokasenna script but getting a really weird error where it prints time_start on the line

Msg("func timestart    "..time_start)

And at the same time gives a error saying time_start is nil, although printing right!

Use Defer from Ultraschall-Api. It's doing what you try to do and allows controlling the defer loop from another script as well, to pause execution of the deferred function or to even stop it.

And you can set it to run the deferred function every x seconds or defer-cycles.

Schwa once posted a wait/sleep Lua example:

Thanks mespotine!!! This a really usefull function instead of trying to do on my own a wait. Nice work!!! Work smoothly here!
