FrameScript_RegisterFunction callback return strange value

[Wildbreath]

[solved]

Hi there!

Have a "fun" with subject.

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
private delegate int LuaFunctionDelegate(string args);
private static readonly LuaFunctionDelegate callback = LuaRegisterCallbackHandler;

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
private delegate void LuaRegisterFunction(string szName, IntPtr pFunc);
private static readonly LuaRegisterFunction RegisterCommandHandler;

LuaRegisterFunctionHandler = Memory.Instance.RegisterDelegate<LuaRegisterFunction>(Offsets.RegisterFunction);
LuaRegisterFunctionHandler(commandName, PatchInvalidPtr(callback));

public static int LuaRegisterCallbackHandler(string args){
   return 0;
}  

callback work as intended, but args return a strange values (not as in sender lua function), where i missed?
(made a CastSpellByID, HandleTerrainClick and etc funcs wrapper, new pqr )

I'm not entirely sure what you're asking, but I'm pretty sure that the FrameScript::Register function also needs a luaState pointer.

register console command - yes, but not register function.
or you about luaState in callback? (gettop, tonumber arg and etc)
btw lua_tolstring in callback still crashing wow. dunno why - lua_tonumber working as intended

same trouble ^

oh wow o .o

as far as I know, your LuaRegisterCallbackHandler needs to accept an integer (the lua vm handle), so you can get your stuff from/onto the lua stack o.o"

just done it, i was trying to return char* as string - fail
now i research how to create trampoline for c#, patching invalidptrcheck is stupid - it need rewrites for every callback and it detectable (but anyway i should write a jmp to my trampoline... any ideas?)
