Persistence

Lifetime configuration

The CoherenceSync editor interface allows us to define the Lifetime of a networked object. The following options are available:

• Session Based. No persistence. The Entity will disappear when the Client or Simulator disconnects.

• Persistent. The Entity will remain on the Server until a simulating Client deletes it.

For managing unique persistent objects, see Uniqueness.

Deleting a persistent object

A persistent object can be deleted only by the Client or Simulator that has authority over it. For indirect remote deletion, see the section about network commands.

Deleting a persistent object is done the same as with any network object - by destroying its GameObject.

Destroy(coherenceSync.gameObject);

Persistent objects are stored

All persistent objects remain in the World for the entire lifetime of the Replication Server and, periodically, the Replication Server records the state of the World and saves it to physical storage. If the Replication Server is restarted, then the saved persistent objects are reloaded when the Replication Server resumes.

Persistent object limits

Currently, the maximum number of persistent objects supported by the Replication Server is 32 000. This limit will be increased in the near future.
