Call Lua function from C++ using LuaBridge

Question

I am having some trouble calling Lua functions from C++ using LuaBridge. The idea is that I want to call "Update" on the script on every game update in C++. The following code is what I have found online:

LuaRef sumNumbers = getGlobal(L, "sumNumbers");
int result = sumNumbers(5, 4);

So in my case this would be:

LuaRef updateFunction = getGlobal(L, "Update");
updateFunction();

However, the getGlobal does not seem to exist in LuaBridge 2.0 (luabridge namespace). This is different from the lua_getglobal

I am wondering if this has been replaced by a different function call or if it has been deprecated out of the 2.0 version. I can of course use the normal C Lua approach, but I was wondering if this has been abstracted in LuaBridge (to make things easier)

Make sure you're using the latest source from the github project repository. When I tested this from luabridge's master branch, luabridge::getGlobal is present and working.
