Join Michael House for an in-depth discussion in this video Saving and loading games, part of Advanced Unity: 3D Game Programming.
…In this video, I'm going to teach you about saving the state of a game…to disk for later loading, commonly referred to as saving and loading a game.…There's no built-in functionality for adding a saved game in…Unity because saving a game is unique to the game.…Each game has a different set of data that needs…to be saved and loaded to represent the game state.…This video will cover both PC and mobile games as well as web.…There is a distinction between the two,…because web games are a more limited platform.…In this case with tighter security.…We don't have the same freedom to read and…write files on the system, when using the web.…
Since saving is so specific to the game you're creating, in this…video I'm going to focus on the general techniques used to serialized objects.…Let's take a look at the code.…Here we have a save/load simple objects class.…It's going to handle saving and loading for us.…In this case, when writing simple objects, which are a type of object in our scene,…we're going to open a file, collect a list of all the simple object in the scene.…
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.
