[QUESTION]How to check when lua_reload

[zys924]

Im trying to keep a registered lua function alive.
Is there a way to check lua reload action when the player is in-game?
It is better to achieve this by memory-read or CFunction call.
thx for helping me!

[mnbvc]

you could set a variable, and if the variable is nil the user did a reload

Currently a function invoked when all default WoW Lua functions are registered is present at 0x00713B10. You can hook that function and reregister your own lua_CFunctions there.

Ive got that CFunction. Also, I've used easyhook to hook that function successfully. Whereas none of my own code was called all through whenever the game is running. Nothing wrong seems happen though...
When is this function called? Or is it a must to hook it right at the process start?

Yes. (filler)

Yes. (filler)

yes what..? Hook right at the beginning? I dont think it is the time when WoW Lua functions are called. At lease I know that the 'print' function doesnt exist at the login screen.

[lanman92]

You think that the login screen is something other than lua?

[tesserajk]

One can call the DefaultLogin lua function on the login screen, so it must have been registered before. In my experience I found that I needed to register my own lua functions after login in order for them to be usable in game. I am not entirely sure of why this is. I do mine when the ObjMgr is initialized.

You can register it every time before you call it.
Yes I'm evil.

[tesserajk]

Haha. That is one option.

Guess the most failsafe way is to re-register every call to CGGameUI__EnterWorld

That, or you can hook one of the 'LoadScriptFunctions' funcs, and always reload your Lua whenever WoW reloads it's own.

or watch luastate changes

        static void* laststate = 0;
        if (laststate != (GetLuaState)()) {
            laststate = (GetLuaState)();
            (FrameScript_RegisterFunction)("ipvtqpfgxkotn", (void*)CallbackFunction);
        }
