Im making an engine in c++ with lua for scripting(using luabridge for the binding), so i have a lot of entities, and those entities has components, one of the components that i have is of course a script component, but, everytime i want to call a different function from a lua file, i always have to call luaL_dofile, and if I do this more than 20 times, i mean, with 20 scripts, my engine gets REALLY slow like, 5 fps. Every script has a Init, FixedUpdate, Update and Shutdown function, so for every script, i call the Init function, for every script i call the update function, and so on... There's a solution for that? I really hope someone could help me.

Some pseudo code:

  //..in void update(float dt)..
    for (int i = 0; i < scripts.size(); i++)
    {
        luabridge::LuaRef func = luabridge::getGlobal(L, "Update");
        if(func.isFunction())
          func(dt);
    }

I'm making an engine in C++ with Lua for its scripting language (using LuaBridge as the binding). I have a lot of entities and those entities have components. One of the components on those entities is a script component. Every time I want to call a different function from a Lua script, I always have to call luaL_dofile. If I call this with more than 20 scripts, my game takes too much time per frame reducing it to 5 FPS on my machine. Every script has an Init, FixedUpdate, Update, and Shutdown function. For every script, I call all of these functions in order. Is there a way to reduce the latency introduced in each frame from using Lua?

Some pseudo code of my usage of LuaBridge:

    // In Update function:
    for (int i = 0; i < scripts.size(); i++)
    {
        luabridge::LuaRef func = luabridge::getGlobal(L, "Update");
        if(func.isFunction())
          func(dt);
    }
