This demo displays how to setup and use the Hash Setup: * Open scene as server, clientHost, or client only. * Press Play. Notes: * Demo only works on clientHost. Real usage works with separate client and server, and clientHost. * Scene view can be used to see objects appear and disappear as the player object moves between grid spots. * See NetworkManager > HashGrid component to update hash grid settings. * Notice that the ObserverManager has GridCondition as a default condition.
