Abstract: Systems and methods for exchanging information in a distributed computing system implementing an interactive application, such as a location-based parallel reality game, are provided. In particular, the subject matter of the present disclosure provides an alternative approach for providing and processing return results from a remote procedure call (RPC) by which remote computing systems (e.g. a game server and a remote client) send requests and responses to one another. Rather than providing a single return result in response to a single request as in typical remote procedure calls, information about updates to the state of the interactive application, such as updates to game status, can be returned via side channels which are handled generically while passing the main return result of the invoked service directly back to the caller.

Abstract: Systems and methods for implementing cross-cutting actions that cut across many remote procedure calls (RPCs) in an interactive application, such as location-based parallel reality game are provided. In particular, one or more decorators can be associated in a source file, such as a Java source file, with a remote procedure call class defining a plurality of RPC methods for the interactive application. Each decorator can be a set of instructions that gets executed before and after an RPC method and addresses concerns that cut across a plurality of RPC methods for the interactive application.
