Hi!

I don't know much of scripting, but I was trying to make a script to log the RNG and it works.

The problem is that while the scrip is running Cheat Engine (7.4) freezes, my script only stops running when I close the game, and only then Cheat Engine resumes to work.

I couldn't find anything upon search that could fix this issue, maybe because I still naive into scripting/CE and things like this. Can I be helped out? thx

Code:

local number1 = readInteger("ePSXe.exe+A8B030")
showMessage(number1)
file = io.open("J:/RNG_Log.txt", "a")
date = os.date("   Session: %d/%m/%Y - %X")
file:write(date, "\n")
::loop::
local function isempty(s)
  return s == nil or s == ''
end
if isempty(number1) then
  goto fim
end
number2 = readInteger("ePSXe.exe+A8B030")
if (number1 ~= number2) then
    file:write(number1, "\n")
    sleep(100)
    number1 = number2
    goto loop
    return
end
sleep(100)
goto loop
::fim::
io.close(file)
return


Thanks for helping.

goto? There's goto in Lua? Huh, easy to forget...

Anyway, Lua code is run in the main thread by default. Only the main thread is allowed to access the GUI. If you block the main thread (i.e. via `sleep`), the GUI stops working.

Don't use goto- Lua isn't an assembly language. Use things like if...elseif...else, for, while, etc. Only use goto if one of these can't solve your problem. e.g. Lua has `break` but not `continue` for `for` loops

You shouldn't keep a file handle open for longer than you need to. You probably don't need to keep it open all the time in this case.

A timer would probably be the easiest way of doing this. Example:
Code:
local function logval(...)
  local file = assert(io.open('J:/RNG_Log.txt', 'a'))
  assert(file:write(...))
  file:close()
end

local oldval = readInteger('ePSXe.exe+A8B030')
if not oldval then return end
logval(os.date('   Session: %d/%m/%Y - %X\n'), oldval, '\n')

if valLogTimer then valLogTimer.destroy() end
valLogTimer = createTimer()
valLogTimer.Interval = 100
valLogTimer.OnTimer = function(t)
  local newval = readInteger('ePSXe.exe+A8B030')
  if not newval then
    t.Enabled = false
    return
  end

  if oldval ~= newval then
    oldval = newval
    logval(newval, '\n')
  end
end

I made a GUI for this a long time ago here:
