Logitech/LGHUB Lua - Loop with break - lua

Question

i recently picked up Lua while making a macro script for my LG mouse.
Unfortunately the Lua-API is really restricted with debug, io and file not working (source: http://www.softpanorama.org/Hardware/Peripherals/Keyboards/Logitech_G_keyboard_macros/lua_scripting.shtml#Limitations)
Here is also the official reference: https://douile.github.io/logitech-toggle-keys/APIDocs.pdf
The script is running a LGHUB macro while i want to attach mouse movement to that macro while it is running. There is no function for checking if a macro is currently running to just loop and stop the lua-side.
So I'm looking for a possibility in Lua to 'run a loop independent' which does not stop the execution of the rest of my script (to check if a status variable [isMacroRunning] has changed). I also want to break that macro if i hit another button while the macro is running.
BUT if i loop the mouse-movement, i cannot trigger another onEvent-function because the script-pointer(?) is still stuck in my loop. My current idea is to break that with a coroutine but iam not sure how to continue while no key-input is happening.
The script doesnt stop and wait if it encounters 'PlayMacro()', also this API-Function has no return value to just attach lua actions to the PlayMacro-function.
There would be also the possibility to transfer the LGHUB-macro (essentially its just pressButton A and leftclick for 40s then release the buttons) but that doesnt solve the problem (at least i cant find a solution within this) with the function being stuck in the loop and no way to break it.
For example, if MouseButton11 triggers a loop and i press MouseButton10, the $arg variable does not change to 10 but stays at 11 because the script-pointer(?) is still in the loop instead of triggering the onEvent function.
The script seems to get executed once at load (example on switching mouse-profiles) and then the onEvent-function listens. If i could somehow run a looping check on [isMacroRunning] while still be able to trigger the onEvent-function, i can make this work. But otherwise i know to little about Lua and its behavior.
Edit1: Added "essential script" which only describes the needed core-functions. This is not working due to a 2nd onEvent cannot be triggered until the 1st onEvent has finished. But the 1st onEvent is designed to break on a variable change. The variable change is triggered in the 2nd onEvent. Needed solution: some kind of workaround or use of other Lua functions to seperate the 1st onEvent execution from the 2nd onEvent.
Essential Script:
```
isMacroRunning = false
function wiggle()
PressKey("a")
while true do
if not isMacroRunning then break end
OutputLogMessage("wiggle\n")
MoveMouseRelative (5, 0)
Sleep(150)
MoveMouseRelative (-5, 0)
Sleep(150)
end
end
function OnEvent(event, arg)
if (event == "MOUSE_BUTTON_PRESSED" and arg == 11) then
isMacroRunning = true
wiggle()
end
if(event == "MOUSE_BUTTON_PRESSED" and arg == 10 and isMacroRunning) then
isMacroRunning = false
ReleaseKey("a")
end
end
´´´
Full Script:
local isMacroRunning = false
coco = coroutine.create(function()
while true do
if not isMacroRunning then break end
MoveMouseRelative (5, 0)
Sleep(150)
MoveMouseRelative (-5, 0)
Sleep(150)
coroutine.yield()
end
end)
function OnEvent(event, arg)
if (event == "MOUSE_BUTTON_PRESSED" and arg == 11) then
isMacroRunning = true
runMacro()
elseif(event == "MOUSE_BUTTON_PRESSED" and arg == 10 and isMacroRunning) then
isMacroRunning = false
runMacro()
end
end
function runMacro()
if isMacroRunning then
PlayMacro('farm')
coroutine.resume(coco)
OutputLogMessage("Start Macro\n")
else
AbortMacro()
OutputLogMessage("Aborted\n")
end
end
coroutine.resume(coco)

Step 1.
Make sure you're not using MB#4 ("backward") in the game.
If some action is assigned to MB#4 in the game, do the following:
choose keyboard button you don't currently use in the game (for example, F12)
goto GHUB(KEYS tab); bind F12 to your physical MB#4
goto game options; bind the action to F12 instead of MB#4
Now when you press physical MB#4, the game sees F12 and executes your old action.
Step 2.
Goto GHUB(SYSTEM tab); bind "Back" to MB#10
Step 3.
The script.
function OnEvent(event, arg)
if event == "MOUSE_BUTTON_PRESSED" and arg == 11 then
PressMouseButton(1) -- down LMB
PressKey("A") -- down "A"
repeat
MoveMouseRelative(5,0)
Sleep(150)
MoveMouseRelative(-5,0)
Sleep(150)
until IsMouseButtonPressed(4) -- btn#4 is bound to btn#10
ReleaseKey("A") -- up "A"
ReleaseMouseButton(1) -- up LMB
end
end
How does it work:
When you press MB#11, the loop starts.
When you later press MB#10, IsMouseButtonPressed() sees that button#4 is pressed, and the loop exits.
