Multiplayer and scores

Hello everyone! I need to make a multiplayer game, switching players who take turns always in the same order. Turn consist just on fire once. Every player has his own HUD with his score. I stored score variables in character class, but Iā€™m not sure if that is right, and how to create controllers with different Character instances with different scores every one. I searched on UE forums but I just found how to disable splitscreen :confused:
I should do everything on C++
