Shared Mode Master Client

Overview

The SharedModeMasterClient is role given to one client in a Shared Mode session. A player with this role will have a few unique privileges that other clients will not have access to.

Assignment

By default, the role of SharedModeMasterClient will be assigned to the player who created a Shared Mode session. Players can determine if they are the SharedModeMasterClient by simply calling NetworkRunner.IsSharedModeMasterClient. This role will be reassigned if...

• The SharedModeMasterClient leaves or is disconnected; a new SharedModeMasterClient will be automatically assigned to one of the clients currently in the room.
• The SharedModeMasterClient executes NetworkRunner.SetMasterClient(PlayerRef player)

SharedModeMasterClient Privileges

As previously mentioned, the SharedModeMasterClient has a few unique privileges.

Scene Management

In Shared Mode, only the SharedModeMasterClient has the authority to manage scenes; this includes any method involved with scene management such as NetworkRunner.LoadScene.

Initial State Authority over Scene Objects

When a new scene is loaded, the SharedModeMasterClient will have StateAuthority over all NetworkObjects baked into the scene.

Is Master Client Object

In the Shared Mode Settings for NetworkObjects, if Is Master Client is set to true, the SharedModeMasterClient will always have State Authority over this NetworkObject. If a new SharedModeMasterClient is assigned, the State Authority for this NetworkObject will transfer to the new SharedModeMasterClient.

Despawning Objects With No State Authority

If a NetworkObject has Allow State Authority Override checked and Destroy When State Authority Leaves unchecked in its Shared Mode Settings, the NetworkObject will not be destroyed if the player disconnects; however, the SharedModeMasterClient can despawn this object despite not having StateAuthority over it.
