CoherenceInput
CoherenceInput is a component that enables a Simulator to take control of a Client's entities, based on the Client's inputs. It is an essential piece of a server-authoritative setup.
When you select Server Side with Client Input in the Simulate In option on a CoherenceSync, coherence will add a CoherenceInput component to the entity.
From this point on, the authority on this entity is split: a Client has Input authority, while a Simulator will have State authority. This means that the Client is not fully in control of the entity, but only has the license to send inputs to a Simulator. The Simulator in turn will process these inputs, elaborate new state, and send it to the Client who can now display the results.
Because of this round-trip, there will always be a delay between the player's inputs and what they see on screen. To make the game more reactive, you might need to implement prediction.
