I have never used Factories before for the simple reason, I don’t understand when I need them. I have been working on a little game in my spare time, and I decided to implement FMOD for the sound. I looked at a wrapper designed for OpenAL(different sound setup) and it looked something like…

SoundObject*
SoundObjectManager*
SoundObjectFactory*

The SoundObject was basically the instance of each sound object. The SoundObjectManager just manages all of these objects. This is straight forward enough and makes plenty of sense, but I don’t get what the factory is doing or what it is used. I have been reading up on Factorys but still don’t really get them.

Any help would be appreciated!

    Think of Factory as a “virtual constructor”. It lets you construct objects with a common compile time type but different runtime types. You can switch behavior simply by telling the Factory to create an instance of a different runtime type.
