Abstract: Systems and methods for a shared virtual environment are provided. The systems and methods include a unique architecture where domains known as “islands” are replicated across various local machines. These islands include objects that publish events. These events include messages that are provided from the island's controller, to a reflector for the addition of a timestamp. The timestamp ensures computational synchronization between all mirrored islands. The timestamped messages are provided from the reflector back to the controllers of the various islands. The controllers incorporate these messages into the existing message queue based upon the message timing. The local machines then execute the messages in time order, until the external message indicates. These timestamp “heartbeats” thus dictate the execution activity across all islands and ensure synchronization of all islands.
