This is the code I have at the top of an AA script:

Code:

[ENABLE]
{$lua}
if syntaxcheck then return end
if process == nil then ShowMessage('Process is not selected.')
elseif readInteger(process) == 0 then ShowMessage('Process cannot be opened. Gone?')
else
if (monopipe~=nil) and (monopipe.ProcessID~=getOpenedProcessID()) then
monopipe.destroy()
monopipe=nil
end
if (monopipe==nil) then
LaunchMonoDataCollector()
-- monoSymbolList is only available if the target is il2cpp and not normal mono
while (monoSymbolList==nil) or (not monoSymbolList.FullyLoaded) do checkSynchronize(50) end -- checkSynchronize requires that memRec is ASynch.
end
end
{$asm}

The memrec with script is set to 'Execute asynchronous".
When I execute the script, I get this error:

Code:

<<CheckSynchonize called from non-main thread "$9F0">>

Any suggestions?

Thank you!

That is wrong. checkSynchronize may never be called inside an async thread

Code:

while (monoSymbolList==nil) or (not monoSymbolList.FullyLoaded) do
if inMainThread() then
checkSynchronize(50)
else
sleep(50)
end
end

There must be a bug here.
When I disable the script and I enable it a second time (mono is active on IL2CPP), I get this error:

Code:

<<Lua error in the script at line 8:...\CEBETA\autorun\monoscript.lua:53: attempt to call a nil value (global 'synchronze')>>

If, after this, I try to enable it a third time, CE starts flooding the LUA log with this message (and CE must be killed to stop this):

Code:

Error:Access violation

The second line in this snippet is line 53 in monoscript.lua:

Code:

if inMainThread()==false then
synchronze(function()
messageDialog(translate('Do not call libmono.terminate from external threads'), mtError, mbOK)
end)
end

Is there a typo here with the 'i' missing?
Searched all files - the string 'synchronze' was not found anywhere else.
