Introducing MV-C: A Unity-Specific Design Pattern

Tags: , , , , , , ,

Last year I introduced a Unity-based model-view-controller (MVC) design pattern and in the many comments on that article, a theme arose. The “model” part of MVC is arguably not necessary since Unity stores so much of the data itself. Today’s article takes that theme and elaborates on it to create and introduce a new Unity-specific design pattern. Read on to see how this adaptation of MVC works!

Iterators vs. Callbacks: Performance and Garbage

Tags: , , , , , , ,

Iterator functions and their ability to yield return values then continue on really come in handy for a variety of situations. Unfortunately, they come with some pretty serious performance and garbage creation drawbacks. So today’s article explores alternatives in various forms of callbacks: delegates, interfaces, and classes. Can they perform better than iterator functions? Can they avoid garbage creation?

Making Enums More Flexible and Extensible

Tags: , ,

Enums are great at what they do: creating a simple integer type with specific values. Their main purpose is to choose one value out of many like enum Color { Red, Green, Blue }. But what if you have data attached to those choices? What if the data is one type for one choice and another type for another choice? What if there are two pieces of data to attach to one choice and only one for another? Today’s article shows a simple pattern you can use instead of enum in these cases to get a lot more flexibility and extensibility. Read on to see how!
