Lua_inject

[luciferc]

So i got it working and i disabled protection check so its all good.

Only problem is i dunno how to do macro like commands for it.

Ex I want to do this

wow.asm.Lua_Execute("/run if not UnitBuff(\"Player\",\"Swift Red Wind Rider\") then CastSpellByName(\"Swift Red Wind Rider\") end");

Typing into game = it works

Lua injecting = Syntax Errors. So how would i restructure it to make it work?

typedef void ( __cdecl * tLua_Dostring )( char * pszString, char * pszString2, void * pState );
Lua_Dostring = ...;

#define DOLUA(x)Lua_Dostring( x , x , GetLuaState())
DOLUA( "AccountLoginUI:Show();" );

If its like this, it should work. Make sure, the string is escaped right. What is that "/run" doing? Isn't that a command to just run Lua-scripts? If yes, you wont need it here.

DOLUA( "if not UnitBuff(\"Player\",\"Swift Red Wind Rider\") then CastSpellByName(\"Swift Red Wind Rider\"); end" ); should work.

Alternatively, do the if () by hand. Execute UnitBuff(), get the return value from the stack, if not, execute CSBN().

Bad bad bad bad bad. Use an inline function, NOT a macro.

Better:
void inline Lua_Dostring( std::string Code, std::string File = "Hax.lua", void* pLuaState = 0)
{
pLua_DoString(Code.c_str(),File.c_str(),pLuaState ? pLuaState : GetLuaState());
}

Tyvm Cypher + schlumpf

Oh whoops. What was I smoking. The params should be like this:
void inline Lua_Dostring(const std::string& Code, const std::string& File = "Hax.lua", void* pLuaState = 0);

Last time I wake up early. >.<

Is there any limit on Lua Injects string size? Like 1000 etc. would that be okay?

[Cypher]

I doubt there's a limit. It probably just parses until it hits a null byte.

Is WoW parsing the .lua files line by line or all at once?

Is WoW parsing the .lua files line by line or all at once?

IIRC, the LUA engine concats everything anyway.

What does it matter?

[schlumpf]

Uhm, I just want to know it? May've been possible that someone would know that. There is no specific reason behind everything ..

[Cypher]

Curiosity IS a reason. I'd be a bit confused if you did things for absolutely no reason. Would probably be a good sign that there's something going wrong upstairs.

I've been coding for 10 years now, I've done injection, but I have no idea how to interface with wow to send lua commands directly. I have a lot of really good ideas on what I can get accomplished after doing this. Could any of you point me in the right direction on where to start? I would like to become part of the scene here at mmowned.
C++ preferred, C#, anything will do. Although my knowledge on ASM is only elementary.

Try the search feature. It's only been covered about a hundred ****ing times.

If you wanna be part of the community, how about READING THE SECTION RULES.

Cypher, thanks for your quick reply. I read your blog regularly.
Objectively, I understand your frustration at the volume of traffic this site gets in regards to bottom feeders.
I mean no disrespect, quite the contrary, I'll make sure to reread the section rules.
My inquiry is to lua injection specifically, which pegs a total of 2 pages on the search.
I've read every post on those two pages, the most informative of which were done by yourself and kynox.
