![]() Every gunshot is rendered and audible from all perspectives at once. If that footsteps happens at the exact same time for each listener (which it would) and they play the same footstep variation, you’ll suddenly get very loud audio as all the identical sounds constructively add together. For three-way or four-way, it could be quadrupled! One footstep happens and… it’s the sound of a group of people taking a step. ![]() Think about it: every single event that happens on screen that is within audible range of all players is doubled for two-way split screen. Setting aside the doubled CPU cost (for two-way split screen) of audio rendering, this scenario would simply cause an unending sonic catastrophe. We should hear all audio from both perspectives, right? Wrong. But from the perspective of player two, who is further away, it should also sound like it’s far away! After all, ears can’t be split. Indeed, it makes sense if: a gun goes off right next to player one, it should sound near to player one. On the audio front, things get interesting.įrom my conversations with fellow developers, the intuition most people seem to have is that audio for each split perspective should render out all the audio audible to each player (i.e. Doing all this extra work places great strains on nearly every subsystem in a game engine. It also means more things are in use and loaded and thus referenced by the garbage collector. Adding more perspectives into the world results in more objects requiring rendering and less opportunities for culling. You can also customize and do much more using the C++ API.Įnabling split screen is ultimately not as simple as toggling a game project option and hoping for the best. To enable split screen in Unreal Engine, you just need to enable the option in your project settings in the Local Multiplayer settings tab and select the split screen mode you want. You can have your friends over and share the same console and jump in and play with your other friends across the world. Often games are made to support local “couch” co-op and remote networked multiplayer. People like playing together online *and* in-person with their friends.įortunately, Unreal Engine supports up to four-way split screen. Then, after the first consoles started offering broadband internet support, we saw a slow drop off in split-screen support. ![]() ![]() Some of my fondest teenage memories are playing split-screen games like Goldeneye and Halo with my friends in pizza-fueled sleep-overs. It was huge in the early days of multiplayer gaming before the advent of console networking support. Split-screen gaming has seen somewhat of a recent comeback in games. ![]()
