Question: How to keep a lua callback registered, after WoW UI is reloaded

[noctural]

I'm able to register a lua callback via injection. After I log out of one character and onto another, the registered callback is now gone (I'm guessing because lua is reloaded during login).

My question is, do most people have an EndScene hook that calls lua_gettype on the registered callback name and check the return value for "nil" or "function" ? If not found, reregister?

I was hoping there would be a better function to hook than EndScene....so I'm not checking every frame. Maybe a method like "Lua engine is loaded" ?

Thanks!

Most of us just hook the LoadFunctions... function. Shouldn't be hard to find it.

Reregister your stuff after the func is called.

Watch for events or register every frame. There might be a method that gets called after a reload but I'm not sure.

Edit:
Apoc beat me. Apparently there is a function to hook.

You don't have to hook anything.

Just reregister whenever the player pointer or the game 'state' changes (there was a global I used to use, can't remember what it was called).

With only an injected dll(no outside process debugging), in order to read the game state on intervals, would I need to hook EndScene?

note: Function hook works.

Why would you hook an engine function over simply hooking endscene? In a private injected bot the former can (not saying it will, but it CAN if the Warden guy decides to up his game) get you banned, the latter won't.

I guess the short answer is that I'm lazy and I understand patching/hooking.. but not necessarily VMT and D3D device instantiation to find EndScene.

This part of your statement shows you know more about it than half the people here who do it. And by that I mean you can find copy pasta here that does it.

(shorter Cypher) hook EndScene

That, and if you're lazy like me; it gives you the same "EndScene" hook, for any current graphics device WoW is using. (OGL, DX9/DX11, etc) If you wanna draw inside WoW, it's different. :P
