Join Michael House for an in-depth discussion in this video Coroutines, part of Advanced Unity: 3D Game Programming.
…In this video we're going to learn about coroutines.…Coroutines are a coding structure, that allows us to delay the execution of code.…We can essentially pause the execution at a specific section of code,…and then pick up where we left off at a later time.…This can be used not only as an optimization technique, but also…is an easy way to make an event happen at regular intervals.…Let's take a look.…A common mistake when starting game programming,…is to implement a for loop for movement.…Of course, we know the entire for loop, will execute within one frame.…Meaning all of these translates, are added together and no visible movement occurs.…
Even worse, this method moves back to the starting position at the end.…Meaning all of this movement is for nothing.…Let's take a look.…Can see that, activating the on MouseDown method.…We've completed moving, even though there was no visible movement.…We can modify this with a coroutine, using the start…coroutine method, and passing in our movement fixed, method.…We can see that, instead of…

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.
