Join Michael House for an in-depth discussion in this video Events and messaging systems, part of Advanced Unity: 3D Game Programming.
…In this video, I'm going to cover a common control structure in game event systems.…Event systems are used to communicate…between objects, systems, and game managers.…These systems typically have events and listeners.…The listeners will subscribe to the events,…also called messages, of a certain type.…When an event is broadcast of a certain type,…its sent to each of the listeners for that type.…What each listener does with that event depends on that event.…Event message could be something like this building has been damaged.…
Then we can have a gooey listener that will display a message on screen about the…building being damaged or where it is, a…worker listener that will try to repair the building.…finally, prehaps the score listener that deduct…points for letting your building get damaged.…The primary benefit of these systems is flexibility.…It's simple to have a object start listening for vent and have it…respond appropriately without needing to touch…the code that is generating the event.…Let's look at a few more concrete examples with code.…

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.
