Abstract: Implementations of the present disclosure are directed to a computer-implemented method, a system, and an article for managing event data in a multi-player online game. The method can include, for example, receiving user input at a plurality of client devices for a multi-player online game that includes a virtual environment; generating user-initiated events for the online game on the client devices based on the user input; distributing any user-initiated events generated on each client device to other client devices from the plurality of client devices; determining at each client device a plurality of derived game events based on the user-initiated events; storing on each client device the user-initiated events and the derived game events in one or more event queues; and determining at each client device a state of the virtual environment over time, according to the stored user-initiated events and the derived game events.

Abstract: Implementations of the present disclosure are directed to a method, a system, and an article for managing the use of global position information in a multi-player online game. An example computer-implemented method can include: identifying a number of random events for which each random event has a plurality of possible outcomes and each possible outcome has a respective probability of occurrence for each random event; selecting a first possible outcome from the plurality of possible outcomes; determining a probability distribution for the first possible outcome that defines a relationship between (i) a number of occurrences of the first possible outcome in the number of random events and (ii) a range of probabilities; selecting a first probability from the range of probabilities; and determining the number of occurrences of the first possible outcome based on the probability distribution and the selected first probability.

Abstract: Logically separating users into isolation groups is described. An example computer-implemented method can include identifying a first group of users of an online system that allows users to interact with one another on the online system. The method may also include grouping the first group of users into a first isolation group. The method may also include identifying a second group of users of the online system separate from the first group of users within the online system. The method may also include grouping the second group of users into a second isolation group. The first isolation group and the second isolation group may include logical boundaries that restrict interaction within the online system between users in the first isolation group and users in the second isolation group. Additionally, the first isolation group and the second isolation group may be hosted on the same server.

Abstract: Implementations of the present disclosure are directed to a computer-implemented method, a system, and an article for managing updates to environment objects within an online application. The method can include, for example, updating, by one or more computer processors on a server, an environment object for use within an online application on a client device to create an updated environment object, and transmitting, by the one or more computers processors on the server, a message to the client device using the online application that the environment object has been updated. A determination is made that the client device requires the updated environment object, and, based on the determination, the updated environment object is transmitted to the client device.

Abstract: Implementations of this disclosure are directed to systems, methods and media for assessing the status of data being stored in distributed, cached databases that includes retrieving, from a data cache, variables which include a cache loss indicator and a non-null value. The variables are analyzed to determine a state of the cache loss indicator. If the cache loss indicator indicates an intentional cache loss state, the cache loss indicator is removed and the non-null value is provided to an application. Otherwise, a cache restore process is initiated.
