Game Programming Patterns by Robert Nystrom
November 2, 2014
Publisher: Genever Benning
"Game Programming Patterns" provides a systematic description of selected patterns from the Gang of Four book and how they apply to game programming as well as other patterns grouped into four categories: Sequencing Patterns, Behavioral Patterns, Decoupling Patterns, and Optimization Patterns. Keep in mind that each time you use a pattern, you will likely implement it differently.
Engineering challenges encountered in game programming:
- Time and sequencing are a core part of a game's architecture.
- Development cycles are highly compressed.
- Multiple programmers need to be able to rapidly build and iterate without interfering with each other.
- Many pieces of software have to interact with each other.
- Performance is critical.
A good design is about how easily we can accommodate changes. Implementing changes is easier when pieces of software are decoupled, i.e. when one piece can be understood and changed without touching another piece. Maintaining a good architecture requires time, effort, and discipline. It's a trade-off: Do I really need this abstraction? Will I ever use this extensibility point? Keeping things simple may be a helpful guidance in finding the trade off. Try to write code that is easy to understand. Note that writing simple code does not necessarily mean it would take less time to create it.
Game development requires iteration and experimentation. It means that development speed is critical. Prototyping comes handy when we only need to test some idea. It's important to throw away the prototype or re-write it once we are done with testing.
Elegant solutions are usually general: a small bit of logic that covers a wide range of cases.

As every developer knows, requirements are subject to change. But when you build adaptability into your code, you can respond to change more easily and avoid disruptive rework. Focusing on Agile programming, this book describes the best practices, principles, and patterns that enable you to create flexible, adaptive code--and deliver better business value.
Expert guidance to bridge the gap between theory and practice:
- Get grounded in Scrum: artifacts, roles, metrics, phases
- Organize and manage architectural dependencies
- Review best practices for patterns and anti-patterns
- Master SOLID principles: single-responsibility, open/closed, Liskov substitution
- Manage the versatility of interfaces for adaptive code
- Perform unit testing and refactoring in tandem
- See how delegation and abstraction impact code adaptability
- Learn best ways to implement dependency interjection
- Apply what you learn to a pragmatic, agile coding project
- Get code samples at: http://github.com/garymclean/AdaptiveCode (VS 2013; unit tests use MSTest and NUnit)

"Refactoring to Patterns" includes:
- A catalog of twenty-seven pattern-directed refactorings, featuring real-world code examples
- General information and new insights about patterns and refactoring
- Detailed implementation mechanics: how low-level refactorings are combined to implement high-level patterns
- Multiple ways to implement the same pattern—and when to use each
- Practical ways to get started even if you have little experience with patterns or refactoring
Fowler: Any fool can write code that a computer can understand. Good programmers write code that humans can understand.
- Using patterns to improve an existing design is better than using patterns early in a new design.
- Patterns are where you want to be. Refactorings are ways to get there from somewhere else.
- We improve designs with patterns by applying sequences of low-level design transformations, known as refactorings.
- It's one thing to learn what a pattern is and an altogether different thing to really understand when and how to apply the pattern.
- Extreme programming (XP) design practices help avoid both over- and under-engineering.
- When you make your code more flexible or sophisticated than it needs to be, you over-engineer it.
- We under-engineer when we produce poorly designed software. It may happen when we are made to work on too many projects at once.
- The book bridges the gap between patterns and refactoring.
API Design for C++ by Martin Reddy

Publisher: Morgan Kaufmann
In the first chapter, the author answers a question "what is a good API?". He concentrates on language-neutral qualities of APIs, such as information hiding, consistency, and loose coupling. For example, he says that each class should have a central purpose reflected in its name and the methods. It's a good practice to have another person review your API to make sure it is consistent and logical. There is also a short refresher on UML class diagrams. In the next chapter, the author describes several patterns helpful in API design: pimpl idiom, Singleton, Factory Method, Proxy, Adapter, Facade, and Observer. There is also a chapter about functional requirement gathering and use case modeling as well as object-oriented analysis and design. Various styles of C++ APIs are described: flat C APIs, object-oriented APIs, template-based APIs, and data-driven APIs. The next chapter discusses several C++ language features such as constructors/destructors, namespaces, pointer and reference parameters, friend functions, etc. There is also a chapter about performance in C++ using const references, forward declarations, data member clustering, inlining, etc. Versioning has its own chapter with an emphasis on API compatibility: backward, forward, functional, source, and binary. The importance of good documentation techniques with an example of using the Doxygen tool is a topic of another chapter. Various types of automated testing (unit, integration, performance tests) and testing methodologies (test-driven development, stub and mock objects, testing private code, and contract programming) are also presented. The last two chapters deal with optional topics such as scripting access to an API and extensibility through custom C++ plugins. An appendix provides information on how to create static and dynamic libraries in C++.

The Cyclone game engine featured in the book was written specifically for this book and has been utilized in iPhone application development and Adobe Flash projects. The companion website will include the full source code of the Cyclone physics engine, along with example applications that show the physics system in operation.
The book covers the creation of a rigid-body, iterative, impulse-based physics engine. The engine supports particle effects, flight simulation, car physics, crates, destructible objects, cloth, and ragdolls. The source code is based on the GLUT toolkit, which wraps OpenGL in a platform-independent way.
Classical mechanics are the laws that govern how large objects move under the influence of gravity and other forces. This is the physics implemented in games: particle movement (bullets, sparks, fireworks, smoke, and explosions), flight simulation, automotive physics, rigid-body, soft-body (clothes, flags, ropes), ragdoll, fluid flow (water, fire, smoke).
If you are a one-person hobbyist working on your game in the evenings, then developing a complete physics solution might take your time away from improving graphics or game play.
Engines that simulate rigid bodies are called mass aggregate engines. They treat objects as a whole. A box might be simulated as if it were made up of eight masses, one at each corner, connected by rods. Mass aggregate engines are easier to program because they don't need to understand rotations. The equations of motion can be expressed purely in terms of linear motion. The whole object rotates naturally as a result of the connections between masses.
It is very difficult to make things truly rigid in a physics engine. Extra code is needed to reconstruct the rigid body from the slightly springy set of masses. This extra code may grow in size significantly. Fortunately, we can extend a mass aggregate engine into a full rigid-body system by adding rotations.

- Genomes - all the genes an organism has (the storage unit of life).
- Proteomes - all the proteins encoded by those genes (the functional unit of life). In any particular individual, the genes in a human skin cell are identical to those in a human nerve cell. However, their proteomes are different.
- Photosynthesis - a process of harnessing light energy by plants, algae, and certain bacteria to produce nutrients.
- Evolutionary change occurs by two mechanisms: vertical descent with mutation and horizontal gene transfer. In some cases, horizontal gene transfer can occur between members of different species.
- Hypothesis - a proposed idea. A hypothesis is never really proven.
- Theory - an established set of ideas that explains a vast amount of data and offers valid predictions that can be tested. Like a hypothesis, a theory can never be proven to be true. Theories are viewed as knowledge.
- Inorganic chemistry - the nature of atoms and molecules, with the exception of those that contain rings or chains of carbon.
- Organic chemistry - the nature of molecules that contain rings or chains of carbon.
