Join Michael House for an in-depth discussion in this video Extension methods, part of Advanced Unity: 3D Game Programming.
…In this video I'm going to show you how to use extension methods.…These are a special type of method that essentially allow you to…add additional methods to a class without having to modify that class.…This is great for situations where you don't want to or can't…create a new derived type just to add a method or two.…Once the extension methods are written, there's no apparent…difference between calling them or the objects built in methods.…Let's take a look at this in code.…Here I've created a static class for extension methods.…In this class, we can put all of our extension method because they're…all going to be static and we can keep them all in one spot.…
This are going to be loaded up by the compiler The…first extension method we're going to be defining is called reset.…The first parameter of any extension method is going to be the this with the…type of the object we want to extend and then the object we're going to extend.…The compiler's smart enough to know that this part…will be removed and we're just going to be calling GameObject.Reset.…

Q: In the Chapter 3 file EntityLoader.cs, I get an error: DirectoryNotFoundException: Directory 'Assets\' not found. Removing the backslash after 'Assets' fixes it, but then I run into a different error. How do I fix this?
Q: What version of Unity does this course cover?
A: This course requires Unity 4.5.5. The newer versions of Unity have done away with the GUI system used in this course, so the interfaces included for many of the scenes will not work with 4.6 and higher. You can download Unity 4.5.5 at http://unity3d.com/get-unity/download/archive.
Q: The game object in the first chapter's Mouse Input Raycasting sample doesn't appear to follow the mouse. What's wrong?
A: Please enable the Box Collider component (by activating the checkbox next to the component name) on the game object. This is not explicitly mentioned in the video, but it will ensure the raycasts collide with the game object.
