I have a non-uobject empty C++ class. I want to send and recieve data(int, std::string etc) from UObject and non-UObject classes. How can I use the standard C++ library(iostrem, vector, string etc.)?
Sample snippets would be nice

You can use it as you would in normal C++.
Just import the right libraries and you’re good (ie #include <vector>)

Though you can’t make any UFUNCTIONs with those types. You’ll have to make a wrapper function if you want to use it in BP
