DoString injections

[jaakko]

Hello, fellow hackers. I've been testing base for my bot and done some DLL injections, but for some reason i can't get my Framescript_Execute to work. I got my offsets from this forum by searching. I'm working with 3.3.5 12340.

This is my declaration:

auto Framescript_Execute = reinterpret_cast<UINT32(__cdecl *)(const char *, const char *, int)>(0x00819210);

I call it in my DllMain and i can clearly see that it gets called by my module and i can follow every step in IDA but not getting the results i want.

I call the function like this:

Framescript_execute("DoEmote(\"cry\");", "cry.lua", 0);

I havent yet tried detouring the wow functions.
Am i heading wrong way? Did I understand the concept wrong?

Thanks.

Call it from the Main Thread... Detouring Endscene(Dx9) or the Dx11 equivalent would be easiest

i'm using Framescript_Execute not in main thread and it works
0x00819210 rebased? (can't see now) try to search it using 'compat.lua' string in IDA and rebase
any lua errors in wow after calling?

Please define "it works". How can you know this function is threadsafe when Lua in fact isn't threadsafe. What if you run into race conditions?

now i understand how, my tool sent command from wow to injection and call lua, so can't call it not in main thread
but warden scanner work in othrer thread and it sometimes call lua functions from wow (print)

If you call lua functions when not in the main thread... its only a a matter of time until you run into issues.

Do you use ASM injection? in a cave thats called from your D3D hook?
