I have an script where I am exctracting an Adress. after that, I want to check the same adress until this change to a new value and continue with my script.

this is my example.

Code:
-- My script where I find the Adress.

MyAdress = -- adress

Value = readDouble(MyAdress)

while true do
  New_Value = readDouble(MyAdress) 
  if ( New_Value ~= Value ) then
    Value = New_Value
    break
  end
end

-- continue my scrip...


the problem is if the value take a lot of time to change, the CE have issues like "not responding" and this happened even if I put a sleep in the loop, I tried to use timer in lua instead to use while loop. but the problem is, the timer start when the whole script is finished. for example.

Code:
-- My script where I find the Adress.

MyAdress = -- adress
Value = readDouble(MyAdress)
timer = createTimer(MainForm,true)
timer.Interval = 100

timer.OnTimer = function(timer)
  New_Value = readDouble(MyAdress)
  if New_Value ~= Value then
     Value = New_Value
     timer.destroy()
  end
end


Code:
-- Continue my script

print('The new value is --> ',Value)


And this timer is working well ending with a new value, but the problem is first the final print is execute, and after that, the timer. I only have some days with lua language, I am still learning. maybe I am not using the timer really well. Any correction on my script I would apreciate. Smile

The reason is, that the code is running continuously in the main thread, thus it cannot proceed and handle other events until it's out of the loop.

On solution is to insert in your loop (while true do ... end);
The following command,
Code:
processMessages();

So C.E would continue to handle messages and won't go unresponsive.

But doing such loop is quite intensive and unnecessary (for this kind of task), so using a timer is much better solution.
Which bring us to the next solution;
Another simple solution is to place the rest of the script inside a function, and from the timer object call it.
Code:
MyAdress = -- adress
Value = readDouble(MyAdress)
timer = createTimer(MainForm,true)
timer.Interval = 100

timer.OnTimer = function(timer)
  New_Value = readDouble(MyAdress)
  if New_Value ~= Value then
     Value = New_Value
     timer.destroy();
     ContinueScript();
  end
end   


function ContinueScript(...)
   print('The new value is --> ',Value)
end
