OutdatedLua Stack Manipulation
Lua Stack Manipulation
Hi, I am going to show you how to figure out how to use the stack.
pretend L was your lua_State pointer, if you do L->luabase, then you get a pointer CBaseLuaInterface class, which contains all of your functions for that state of lua. Why does this matter? If you don't want to be a douche, then you won't use the Gayry (or blackawp) headers, and you will make the headers by yourself, and that was just a headstart in the right direction.
Stack Manipulation:
Did you know that you could use the lua stack functions without creating a function? You didn't? Well you don't know much then...
you can create a hook in C++, and call lua functions to get info you needed. For example, can you not find that pony riders name in darkrp on your esp? It might be because you are using the c++ function that reports their steam name; not their in-game name. There's a fix for that!
To find a player's name in lua, that is simple:
Now we can use the lua stack to get it into c++.
and ta da now you have your in-game name
Use the stack to your advantage. Good day.

To find a player's name in lua, that is simple:
Code:
Entity(entindex):Nick();
-- or the real way
FindMetaTable("Player").Nick(Entity(entindex));
Code:
LU->PushSpecial(0); // push the global table
LU->GetField(-1, "FindMetaTable"); // get FindMetaTable off the global table
LU->PushString("Player", 0); // push the string Player
LU->Call(1, 1); // call FindMetaTable with one argument and get one return
LU->GetField(-1, "Nick"); // get FindMetaTable("Player").Nick
LU->GetField(-2, "Entity"); // get the entity function off the global table
LU->PushNumber(ply->entindex()); // push the player's entity index
LU->Call(1, 1); // pop the entindex and entity function off the table and get the return
LU->Call(1, 1); // pop the entity and the Nick function off the stack and get the return
const char* _name = LU->GetString(-1); // get the name from the return
LU->Pop(2); // pop the table and the return off the stack
Use the stack to your advantage. Good day.
Next time, use different terminology.
I took the liberty to change some of your foul language.
Foul language is best kept in the General section.

Awesome.
Now I just need to learn C++.

You could actually reverse engineer how the game uses the Nick function and just call it in C++ without the need for Lua. Stop posting this garbage you clearly stole from the tutorial on the wiki that I wrote.
Is it possible to load lua with c++ into gmod so that no bypassed or luau open script is used or needed? Idk if gmod accepts c++ and lua together that way
...yes that's how all lua is loaded...

you're talking about by c++? So when opening it via console that is also c++? That means you can manipulate how that loads and use it without needing any bypass?

no, lua is written in pure lua that's what makes it work
Woah c++ looks hard ;(((
