Join Michael House for an in-depth discussion in this video Debugging, part of Advanced Unity: 3D Game Programming.
…In this video I'm going to tell you about debugging.…In general terms, this is the process of finding and removing bugs from the code.…The Debugger is a tool that allows us to…do this by analyzing the program during run time.…It's not only great at catching run time errors…but it provides a suite functionality that allows us to…view the current state of the program at any…given point, allowing us to find logic errors as well.…With the Debugger, we can pause the execution…of the code at break points, inspect the current…state of the variables, step line by line…through the code, and even modify values in memory.…
The Debugger should be your go-to tool for…solving run time errors and analyzing algorithm errors.…The difference between these two is simple.…Runtime errors cause an exception in the game.…If the exception is not handled, this will cause the game to crash.…These errors can arise from a number of situations.…One of the most common runtime errors is a null pointer exception.…This error happens when you try and use an object that has not yet been initialized.…
NOTE: 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: 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.
