 Posted: Mon Feb 03, 2025 3:37 am Post subject: Calling Mono method crashed the game in a strange way |
 |
|
Hi,
I tried to use aa script to call the mono game method `UpdateQuest`, which manages the player's new tasks and progress. The strange thing about it is: the script ran without problems when I just launched the game and loaded the save. BUT after I proceeded with a task or finished one in the gameplay (both would trigger the game process to use the `UpdateQuest` method), calling the method with the same aa script often led to a game crash.
I know the game had less free memory because `alloc()` often allocated memory over 2 GB away from where the method was located. Does that have anything to do with this crash?
Here is my script (I am sure the mono feature was opened when used):
| Code: |
[ENABLE]
alloc(InvokeMonoClassMethod, $100)
createThread(InvokeMonoClassMethod)
alloc(self, 8)
InvokeMonoClassMethod:
sub rsp,28
call mono-2.0-bdwgc.mono_get_root_domain
mov rcx,rax
call mono-2.0-bdwgc.mono_thread_attach
mov [self], rax
mov rcx,23A26ABC1E0 // the QuestData class instance
mov rdx,83D // questID
mov r8d,1 // quest progress
mov r9d,1 // progress status
call QuestData:UpdateQuest
mov rcx,[self]
call mono-2.0-bdwgc.mono_thread_detach
add rsp,28
ret
[DISABLE]
dealloc(self)
dealloc(InvokeMonoClassMethod)

likely the QuestData class instance (23A26ABC1E0) changed upon loading a save/restart the game

No, it wasn't.
It is not a script for automation. I got the instance address from another script and then copy-pasted it back here in this script whenever restarting the game process. I also ensured the instance address hadn't changed when I proceeded/finished a quest in-game.
The crashing went as follows:
1. Launched the game
2. Loaded a save
3. Ran script 1 to get the instance address of `QuestData`
4. Copy-pasted the address back to this script, right after `mov rcx,`
5. I hadn't done anything about quests in the game so far
6. Ran this script multiple times with different rdx, r8, r9, all succeeded
7. Proceeded with any quest in the game, the game itself would use the same method to update quest statuses
8. Used script 1 to check the instance address of `QuestData` wasn't changed
8. Ran this script again, the game crashed (not always but often)
I've checked everything I could. Quite frustrating.
