Can you tell me more about the feature and can guide me how to use it, thank you
I really admire this idea. This is something that can speed up the development and debugging of mods several times.
As a friend, I suggest that if you have enough knowledge, please develop a debugger without problems in Visual Studio. If the company does not mind,
Hi @ShinyWasabi ...
What an amazing tool mate! Thank you for developing it for our community.
I am trying to debug a SCRIPT named BulletKnockback.dll (https://www.gta5-mods.com/scripts/bullet-knockback) ... I just see several controllers (Audio Test, cellphone_controller,etc) in the DROPDOWN list but I cannot see the BulletKnockback there ... Anything that I am missing :)?
The correct link is https://www.gta5-mods.com/scripts/bullet-knockback
@patrio @jrchaves
This tool is designed for debugging the game’s YSC scripts, mainly for reverse engineering and research purposes.
It’s not intended for ASI or DLL mods.
Where can I download ScriptVM.asi? It seems that the compiled file is not published on the page you provided.
@JoyLucien For now, you’ll need to compile it yourself from the source. I’ll publish a compiled release once I add Legacy support for it.
@ShinyWasabi, Ah ok ... thank you for claryfing. I will try to work with YSC and check the results. Thank you mate!
Such a useful mod!
x64dbg on crack
is ScriptVM no longer required? i see the git repository is no longer available
@ook_3d I merged its code into the scrDbg repository, and it’s now built as scrDbg.dll and injected into the game by scrDbg.exe. I’ll publish a new release soon.
