Join Michael House for an in-depth discussion in this video The Call Stack, part of Advanced Unity: 3D Game Programming.
…On this video, I'll teach you about…the CallStack and its importance for debugging.…The CallStack is a list of functions and their locations in the program.…You can think of a CallStack like a map, leading back to the start of the program.…Recall, in the debugging video, we used the debugger to step into a piece of code.…Whenever the execution steps into a function…call it leaves a marker on the stack.…It's called a stack because like the stacked data…structure, items are added and removed from the top only.…In this way, stepping into or calling a method will push a marker onto the…stack, and stepping out of or returning from a method will pop a marker off.…
Let's look at an example of this with the following code.…Setting a break point on D, attaching to the Debugger, and playing our scene.…We can see our call stack down here in the lower right.…And see that from the start, we read this backwards to be…functionC called functionD, functionB called functionC,…functionA called functionB, and start call functionA.…
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.
