C# event manager design in Unity3D. Usability and productivity evaluationDuring a Unity3D-based application development arose a problem of the best approach to a modular
architecture. Main requirements were extensibility of a system via plugin mechanism, good performance
within single main loop, aggressive garbage collection tolerance, low memory footprint and
minimal amount of allocations. Event-driven architecture has been chosen as the one fitting the bill.
This paper describes three different approaches to a message exchange within such an architecture,
their relative ease of use, ease of maintenance and performance. Message exchange mechanisms being
reviewed are: C# native events, event manager with event and publisher types tracking, static events
lists with responsibility demarcation and tight IDE integration. All three methods are supposed to be
used inside Unity3D version 4 hence being single-threaded and .NET 3.5 compatible. In the end static
events lists approach has proven itself although a little bit more verbose than the two other methods,
however the best one in terms of performance and IDE integration. The best thing about the selected
approach is the fact that it shifts considerable part of an abstraction overhead into an application compile
phase rather than runtime. Considering all being said static events lists approach is the best one
to use within Unity3D applications.
