Start 2 Tasks at the same Time

[Kiliaan]

Hey!
Im a beginner at Livecode and my englisch is very bad so please dont judge me.
I have a big Problem: Ich just want to start two methods at the same time by clicking one Button. The Problem is that when i click the Button the first method starts, but the second doesn't start.
The code just looks like that:

on Mouseup
starter1
starter2
end Mouseup

start1 and start2 are the two Methods.
I hope someone knows a good way to fix my little Problem with Livecode.
Thanks Kiliaan

EDIT: This is the Code the Problem occured

Code: Select all

on beginn
   go to card "game"
   put 1 into stacky
   put 0 into frager
   put 4000 into  timer
   put 4500 into timer2.1
   put 0 into score
   put score into fld "lab"
   
   wait 3 seconds

   starter1
   starter2

end beginn

on starter1
   
   put timer-100 into timer
   put random(timer) into timer2
   if timer2<300 then
      put 300 into timer2
   end if
   wait timer2 milliseconds with messages
   set backgroundcolor of grc "g1" to "green"
   start1.1
end starter1

on start1.1
   if stacky = 1 then
      
      repeat with t = 1 to 11
         if clicker1=1 then

Hi Kiliaan,
Welcome
I think you can not start two task exactly in the same time.
I believe there is a before and an after in LiveCode.
I'm surprised that your start2 message is not sent and you haven't got an error message
if there is not a start2 message.

Create one btn and one fld in a empty cd
put this script into your btn

Code: Select all

on Mouseup
   starter1 
   starter2 
end Mouseup

on starter1
   put "starter1" && the milliseconds into line 1 of fld 1
end starter1

on starter2
   put "starter2" && the milliseconds into line 2 of fld 1
end starter2

You might use params and in this case you may do

Code: Select all

on Mouseup
   starter 1 
   starter 2 
end Mouseup

on starter pNum
   put pNum && the milliseconds into line pNum of fld 1
end starter

Best regards

Hey Thanks for your fast reply!
But unfortunately this doesnt work for my projekt, in which this problem occured.
I edited my first Question, I hope this helps to understand where my problem is.
Hope you can help me solving this problem.

Thanks, Kilian

Hi
I see "start1.1" in your script
The correct syntax should be "start1 1"
Message and space and params separate by comma. MyMessage param1,param2 etc...

you have to declare variable on top on script like that. If not, all variables aren't empty after "end beginn"

Code: Select all

local stacky, frager, timer, timer2.1, score
on beginn
--   ...
   put 1 into stacky
   put 0 into frager
   put 4000 into  timer
   put 4500 into timer2.1
   put 0 into score
 --  ...
end beginn

Thanks for your fast Reply

I left some Parts from my code out, to show you my Problem a bit better...
I decleared all Vars correctly, and changed the Syntax like you showed me....
But anyways, the same Problem

But Thanks for helping me trying to fix my Problem, i appreciate this alot

Try this:

Code: Select all

on beginn
   send   starter1 to me in 0 sec
  send    starter2 to me in 0 sec
end beginn

Like Python and some others, LiveCode is a single-threaded engine, so true parallelism is out. But unlike Python, LC has no explicit means of interleaving execution, so even concurrency is not LC's strong suit.

That said, there are ways to emulate concurrent style using timers and other options. This stack illustrates a few:
http://fourthworld.net/channels/lc/IdleHour.rev

If this were a desktop app you could have both concurrency and parallelism using multiprocessing as opposed to multithreading. With the ability to spawn faceless processes easily, multiprocessing can be done very effectively in LC. I haven't tried multiprocessing on Android, howerver, so I have no sense of how useful it'll be for your app (and given RAM constraints on mobile devices may not be worth the effort).

If you provide more info on the specific task you're looking to achieve we may be able to provide more specific guidance.

Yes, probably another solution is

Code: Select all

lock screen
.... all you code here...
unlock screen
