It's quick and easy to set up a networked scene from scratch using the coherence SDK. This example will show you the basic steps to sync up some moving characters.

Add these components to your scene to prepare it for network synchronization.

1. Add MonoBridge

coherence > Scene Setup > Create MonoBridge

This object takes care of connected GameObject lifetimes and allows us to develop using traditional MonoBehaviour scripts.

2. Add LiveQuery - hierarchy

coherence > Scene Setup > Create LiveQuery

Creates a LiveQuery which queries the area around the local player to get the required information from the Replication Server. You can surround your entire scene in one query or can attach it to an object such as the player or a camera.

3. Add the sample UI

coherence > Scene Setup > Add Sample UI

Creates a Canvas (and Event System if not already present in the scene) with a sample UI that helps you connect to a local or remote Replication Server. You can create your own connection dialog, this one is just a quick way to get started.

Using the coherence Hub window

Using the coherence Hub window gives you an overview of everything related to networking in your project. The Overview tab will show you the current status and which actions you need to perform for everything to work.

Automatic issue solving

If we have identified any issues in your project, the Overview tab provides a one-click solution to solving it. In the example below, simply click the blue link next to the warning messages and coherence will redirect you to the correct place to learn more about how to fix the issue.

The coherence Sample UI is a Prefab that you can add to your scene. It handles interaction with coherence services, is made up of a Unity UI Canvas and includes everything needed to handle connection to coherence.

The UI component on the root of the Prefab allows us to switch between using Rooms or Worlds. Each of these methods has a dedicated dialog for connection.

The Auto Simulator Connection component is used by Simulator builds to connect to the relevant Replication Server.

The Rooms Connect Dialog has a few components that facilitate the usage of Rooms.

At the top of the dialog we have an input field for the player's name.

Next is a dropdown for region selection. This dropdown is populated when regions are fetched. The default selection is the first available region.

Beneath these elements is a Rooms list of available Rooms in the selected region.

After selecting a Room from the list the Join button can be used to join that Room.

The New Room tab will take us to the Room creation screen.

This screen contains controls for setting a Room's name and maximum player capacity. Pressing the Create button will create a Room with the specified parameters and immediately add it to the Room List in the previous tab. Create and Join will create the room, and join immediately

The Worlds Connect Dialog is much simpler. It simply holds a dropdown for region selection, an input field for the players name, and a Connect button.
