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.

For more information on how to setup and configure inputs for a CoherenceInput component, refer to the server-authoritative setup page.
