In a previous article I wrote about the ubiquitous observer pattern, which is all about objects (called observers or listeners) that need to be notified when other objects in the...
C / C++ / Development
Now that I’ve got a working game engine it’s time to add some interesting features to it. One that I’ve always desired to implement is online multiplayer, the ability to...
Graphs are a collection of nodes (also known as vertices), connected by edges (sometimes called arcs). A graph is called undirected if the edges connecting the nodes have no direction,...
This article is a brief summary of how to write the differential equations of motion for a rigid body. From these, we can use a finite approximation to calculate a...
Polymorphism is the ability to use objects of different types in a generic way, using the same notation. In C++ there are two forms of polymorphism, dynamic and static polymorphism....
Encapsulation is a staple of object-oriented programming: by hiding (or “abstracting away”) the implementation details of a class behind a public interface we can create abstract data types. Users of...
Templates are a very powerful feature of C++: they let us parameterize a class, function or variable with some generic types or values (called template parameters), so that by specifying...
The Strategy design pattern is a perfect example of the OOP tenet that says: “favor composition over inheritance”. Inheritance is indeed powerful when it comes to code reuse, or when...
Many systems wait continuously for the occurrence of some event, and they react to the event by performing computations or changing their state. Once the event is handled, they go...
According to the GoF book, the intent of the Composite pattern is to “compose objects into tree structures to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions...
