niemand-sec / luahook Goto Github PK

Hello,

I find your lua hook very useful and I wanted to test it on modded vermintide 2 realm with EAC disabled.
I receive random crashes and spent several hours straight trying to understand whats going on.
It starts correctly with lua state = 0 and new lua state = 0 (game offset correct)
Clicking Home (changed hotkey from F9)...
Getting 0 0 again, worked, fire mage boosted levels.
2nd time, same
3rd time, lua state=0, new lua state=4 and getting memory access violation and address like 0x0000000000010 for instance

I have few experience with lua. I tried hooking lua_settop and call val.lua_settop_p(lua_State_ptr, 0); to clear stack but without a luck.
Also, checked creating new lua thread whens its value=4.
Sometimes i sucessfuly execute lua like 5 times in a row and crash and sometimes crash after 1st or 2nd.

May you help me?
Can we catch these exceptions (despite lua is written in c) and take action or continue loop?

Cheers,
Filip

Hi there,

Amazing project you have here! I would have never thought I could have ever gotten this far with the help of your project, I loved the read @ https://niemand.com.ar/2019/02/15/why-leveling-if-you-can-just-use-lua-hacking-lua-inside-games/ and totally enjoyed it, it was let me to actually implement this into another game and low and behold, it works like a charm, I had to make some changes, e.g. the Lua is embedded in my target so I had to remove all references when you get the lua51 module instead I had to manually find the function (gettop, settop, loadfile, etc., etc.) addresses and so on...

Now my thing is that I have been trying to understand how this works and this projects has broaden my very limited knowledge on hooking lua and working with it in general, my issue comes from trying to output the actual print from lua itself to the allocated console... however I haven't been able to accomplish this...

It just won't print... either print("hello world") nor io.write("Hello world, from ",_VERSION,"!\n")

So I'm actually writing all my output to a file, which is quite unconventional knowing I have print available but it does not works.
