Help with getting Client lua state when hooking from Menu State
What's up, guys. I'm having trouble getting Client Lua state when using a module from menu state. I am already hooking from CreateLuaInterfaceFn but I'm having trouble getting it all working. Any hooks you guys can recommend or headers I might be missing/not thinking about?
For reference, I'm trying to call lua hooks between menu and client for a bot I'm building. Due to the bot running in client and the management/'backend' running in menu I'd like to notify menu on completed tasks etc.
The codebase is from the loonix branch of 'gm_roc' (credits to LennyPenny and meepen) because it seemed the closest to my use case. So I hope that helps if you wanted to see the headers and structs I'm using
I've been a software engineer for a number of years but I've never really gone near C++ before. So sorry if any of this cringes you out. Simple modules seemed fluid but going into hooking and process level stuff, I'm lost. Appreciate any help!
