_NetworkHistoryServer

Inherits: Node

Tracks the history of objects' properties

Description

Specifically, history is stored for rollback state properties, rollback input properties, and synchronized state properties.

Keeping history lets rollback restore earlier game states for resimulation, and enables _NetworkSynchronizationServer to send diff states by comparing against historical data.
