Interfaces are important C++ classes that are accessed by the engine. To use an interface you create or modify an inherited class, then cast back to the interface class in a global pointer with a predefined name.
Warning:Never, ever modify an interface class itself. You should always inherit then cast back.Example
IInput* input = new CInput;
This creates the IInput* input object the engine expects, placing behind it Valve's basic input code from CInput.
You are free to modify CInput or to create your own inherited class and use that instead; just remember that only the members of IInput are known to the engine.
