[Question] Lua Callback: Return table of values

[DrakeFish]

Hi there. I'm not sure if this was answered before, search didn't return anything when I searched for the functions I will be asking info about. I am currently working on Lua Callbacks for an injected app and I would need to return a table of values (so we can return the list from CurrObjectMgr). My idea with this function is actually to return a table of the GUID of all loaded Objects so the Lua scripts can get information from them by calling other functions that take GUID as parameter (and eventually return all objects by type). This idea should work pretty good, but I'm really unsure on how I can return a table. I've searched a bit on google and found this post which explain just well the concept of it. My problem now is that we don't have the lua_settable function in the dump here. And search showed me that nobody ever talked about it here, so I guess there must be an alternative or something.

I would like some tips on either an alternative to this or where/how to get the lua_settable function address.

Thanks for any help.

I answered your thread. No problem.

Look at Script_GetItemStats. It calls a function to set a tables values. 0x433B0 is lua_settable.

I'm surprised when you say nobody has posted the address before though. I'm almost certain they did, because I have it in my old dumps, and I never used it for anything. The only other explanation would be that Greyman or Kynox used it for something (we shared IDBs) and never bothered to post it here...

Hey. Thanks for the address and the tips, it ended up working very well. But I still have another question about the lua_Xxx functions. I'm currently trying to do some other stuff using lua, but I, once again, found a function address I'll need to use that isn't in the dump. This one is lua_newuserdata. I'm actually wondering if there's a way to get those functions other than (trying to) compare WoW functions with the Lua.dll (I'm using v5.1.4) functions. As I expected, the WoW functions aren't identical to the Lua.dll functions, and some of them just look very different , making it hard to end up finding the good function using this method. I would probably end up finding it, but an "easier" method wouldn't be refused.

Thanks for any help about this.

ps. this is what I'm currently working on

You can find all those functions in leaked Mac binary with function names.

Lua function 'newproxy' will call lua_newuserdata. In v4.1.0.14007, the address of luaB_Lnewproxy is 0099DC10, I think the second function it calls: '0099DC22 call sub_443BC0' is lua_newuserdata.

I checked ida only, please confirm by yourself.
