[HELP] create character question

[leather]

I want to show the creating new character sence by calling the lua function,so please help me when i push the button "create new character" ,which lua function will be triggered ? and what the function address is?

[flo8464]

CreateCharacter 0x483210
Maybe ?

Here is a dump of all available lua functions before the world is entered: http://nopaste.org/p/aW1BOojUbb

[leather]

thanks flo8464
but i want to show the creating character sence before creating new character.
just like this lua function: RequestRealmList 0x480d90
when i call RequestRealmList, a new frame with all of the realms will be shown.

I'm not sure about this, but I think you have to use SetGlueXML or something like that.

It's SetCurrentScreen. 0x47ED60.

[Nesox]

DoString("SetGluescreen(\"charcreate\")");

you have to run that from the render thread it won't work with remote threads it will throw an ASyncRead != FALSE exception.

[lanman92]

Wasn't there a thread on that issue a LONG time ago?

[Nesox]

There was one on gd, I started it I. Was having problems calling SetGluescreen but it was because wows mainthread keeps acessing the models or something

Thanks to Nesox
DoString("SetGluescreen(\"charcreate\")"); it works!

Where can i get more information about "SetGluescreen" ?

Maybe with your disassembler? Can't be hard to look where its referenced etc.

[lanman92]

I don't think that's built into the code. Might be in Interface/ files inside locale.mpq. That'd be my guess.

I'm right Interface/GlueXML/GlueParent.lua. Turns out SetGlueScreen is just a wrapper around SetCurrentScreen.

int __cdecl lua_SetCurrentScreen(lua_State *L)
{
  char ST10_1_0; // ST10_1@0
  lua_State *refL; // esi@1
  int result; // eax@2
  char *pszScreen; // eax@3

  refL = L;
  if ( sub_801BA0() )
  {
    pszScreen = FrameScript_ToString(refL, 1, 0);
    CGlueMgr__UpdateCurrentScreen(pszScreen);
    AsyncFileReadWaitAll();
    result = 0;
  }
  else
  {
    FrameScript_DisplayError(refL, "Usage: SetCurrentScreen(\"screen\")", ST10_1_0);
    result = 0;
  }
  return result;
}

Strange, my output is showing something different....

// <"Usage: SetCurrentScreen("screen")">
int __cdecl lua_SetCurrentScreen(void *pState)
{
  int Result; // eax@2
  char *pScreen; // eax@3

  if ( sub_801BA0(pState, 1) )
  {
    pScreen = LuaToString(pState, 1, 0);
    sub_47B500(pScreen);
    AsyncFileReadWaitAll();
    Result = 0;
  }
  else
  {
    LuaError(pState, "Usage: SetCurrentScreen(\"screen\")");
    Result = 0;
  }
  return Result;
}

Most notably, the call to LuaError has two params...

EDIT:

@Apoc, do you really need the instruction comments enabled? :s

EDIT:

The disassembly agrees with me. It says you fail:
push offset aUsageSetcurren ; "Usage: SetCurrentScreen(\"screen\")"
push esi
call LuaError

Na, don't need them enabled at all. Just lets me skim through ASM much faster with it enabled. (Saves me ~5-10s per function I read)

Also, I'm fairly certain its just the difference in HexRays versions. It is passing 2 args to the sub_801BA0 call. HexRays just sees it not used, and assumes it's 'bogus'. (Complete, utter, speculation there...)

Edit; Er... that function call is just a sanity check anyway.

[lanman92]

Is there a cracked hexrays? That's pretty nice looking.

Only a very old version.
