I know Unity abandoned their old networking and is working on a new one, but at least there are open source options like mirror, and paid options like photon fusion.
The answer is no, you have to write your own networking. They provide enough to say, “Yes, we have multiplayer support,” but the real answer is “No,” because you still have to do it yourself.
It’s a farce. It’s like including fmod bindings and saying yes we support fmod, but having zero integration.
There’s no serialization, deserialization, no prediction, no reconciliation, no interpolation, nothing.
