Developing a game engine has taught me more than I ever imagined. Now, I want to share what I know with you. Enjoy.
In this page you can find the following topics:
- Game Engine Development
- Metal Projects (new Apple Graphics Language)
- OpenGL ES 2.0
- OpenGL ES 2.0 Projects
- 3D Math
- Design Patterns
I share my experiences as a Game Engine Developer on Quora. Don't miss my answers: @haroldserrano

To develop a Game Engine, you can use any language you want. I use C++. It is fast and powerful. If you are planning to develop your engine using C++, I recommend you to read these articles.
C++ Basic Knowledge
- How to use virtual destructors
- How to use namespaces
- Always initialize C++ Objects
- Use const whenever possible
- Never call a virtual function during destrucion
- Have assignment operators return a reference to *this
- Be sure to copy all of an object's data members and its base class parts
- Avoid using exceptions in destructors
- Use objects to manage resources
- Know when to use delete and when to use delete
- Store newed objects in smart pointers in standalone statements
- Make interfaces easy to use correctly and hard to use incorrectly
- Prefer pass-by-reference-to-const to pass-by-value
- Don't return a reference when you must return an object
- Delay construction of objects until they are needed
- References are Aliases, not Pointers
- How to remove vector elements in a loop?
- Prefer pre-increment to post-increment
