 Posted: Sat May 25, 2024 1:11 pm Post subject: Need help telling Cheat Engine to wait until a DLL is loaded |
 |
|
I have the following script:
| Code: | while getProcessIDFromProcessName('helldivers2.exe') == nil do
sleep(100)
end
OpenProcess("helldivers2.exe")
errorOnLookupFailure(false)
while getAddress("game.dll") == 0 do
sleep(100)
end
local base_scripts = getAddressList().getMemoryRecordByDescription("Base Scripts")
for i=0, base_scripts.Count-1 do
local script = base_scripts.Child[i]
while not script.Active do
script.Active = true
end
end
closeCE() |
The problem is, the script just gets stuck waiting for game.dll to resolve. I have encountered this before manually doing this with HELLDIVERS 2. For some reason, Cheat Engine only grabs the list of mapped in modules when you attach it, not when you attempt to resolve a symbol, so the problem here is it will never escape the while game.dll == 0 loop regardless if the game has mapped in the dll.
How can I fix this?

Running Lua code blocks everything else from happening in CE. Calling functions like processMessages or reinitializeSymbolhandler sometimes helps, but you're better off changing your synchronous blocking code to be asynchronous.
| Code: | getAutoAttachList().add'helldivers2.exe'
local t = createTimer()
t.Interval = 100
t.OnTimer = function()
if not getAddressSafe'game.dll' then return end
local m = AddressList["Base Scripts"]
for i = 0, m.Count - 1 do
-- no need for while loop- this is blocking, and if it fails to activate the first time, it probably won't work the next
m.Child[i].Active = true
end
closeCE()
end |
PS: right click memory record -> Group config -> Activating this entry activates its children

reinitializeSymbolhandler(true)

This doesn't work if it was attached before it was mapped and Game Guard was active. If I use a Game Gaurd bypass that shuts it down completly, it will work and it can find User32 and game.dll after it's been mapped. But if I load Cheat Engine after game.dll has been mapped with Game Guard active, my script will work.

Using a timer causes Cheat Engine to actually load, which causes Game Guard to detect it. If it doesn't load its main window, Game Guard never detects it, asynchronous threads are not an option.
