Lua Unlocker

[NeoBeivo]

Hi,

From Ohack I have extracted the following information

" // Unlock Lua
const byte LuaUnlock[] = {0x8B, 0xE5, 0x5D, 0xC3};
Write(WoWBase + SomeLuaFunction + 0x21D, LuaUnlock, 4);

// To stop those damn pop-ups
const byte NoPopups[] = {0x90, 0xE9};
Write(WoWBase + CGGameUI__ShowBlockedActionFeedback + 0x10, NoPopups, 2);

"

How can I do to be able to execute that without executing all the hack. Is there any option to convert that in something I can handle using cheatengine?

Any LUA Unlocker for 4.3.4?

Thank you
Regards

Do some reading in memory manipulation (and maybe code/DLL injection).

Is there any option to convert that in something I can handle using cheatengine?

• Click on "Add Address Manually"
• put the absolute address to the memory space you want to edit (something like wow.exe+ABC123+21D) in the address field
• set type to "array of bytes"
• set length accordingly
• hit ok
• double click on the value field inside the table
• change the bytes to your patched bytes

But there are better ways then this...

Hi Xalcon,

Thank you for the answer.

Could you explain me one of the ways to do that in a better way?

The best way to do a Lua unlock is to hook the Lua precall functions. They're the 3 functions that call the Lua C functions. In the hook, before calling the original function, set the value of the global variable that's used in the "protected" checks to zero. The global variable is referenced in the first cmp instruction in CGGameUI::CanPerformAction.. That unlocks every Lua function. The Lua unlock I used in that version of OHack doesn't unlock every function. That method is detected on retail, so you should probably check if it's also detected on the private server you're using.

Hi NeoBeivo!

Unlock 4.3.4 (a private server) is something i also would like to do. I am new to wowhacking anyway, and at this time, i am a bit stucked in collecting information - working on it at this moment. If you have some fresh meat to share, that could help me speed it up. In return, i can share my project - this topic seems the perfect place for that.

Best Regards,

Just wondering what are the precall functions? doStirng, pcall ect? t? I have no issue finding the global address for the check in CanPerformAction. Also right now i just call FrameScript_executebuffer. How is the way you described better? Just curious.

Thanks,
