In my current project i want to use a third-party library (Lua) for modding-capabilities, which would include ai, actors aswell as ui widgets,
The problem i have is : Accessing a Lua state is not thread-safe, it should be accessed by only one thread at any given time (that includes reading and writing). I only need it for gameplay logic/ai logic/behavior trees and UI.
I only know that in Unreal 4 rendering is done in a separate thread (which is something my lua state wouldn’t come in touch with at all so no problem there) and i read that physics area also done on a separate thread, but i’m unsure about the rest.
Now the question : is all the game logic, like all the tick-events/tick-functions, aka
-player controller lotic,
-ai controller logic,
-player controller logic,
-the ai behavior tree logic/BHT tasks and
on the same thread in Unreal 4?
If not, is there any page that shows what threads Unreal 4 has for what engine feature so i can make some proper adjustments?
The only helpful answer i found so far was this topic
but they didn’t seem to be 100% sure and before i stumble into errors or make unneccessary adjustments i want to make sure.
