Join Michael House for an in-depth discussion in this video Progress bars, part of Advanced Unity: 3D Game Programming.
…In this video, I'll show you how to create a progress bar GUI component.…Progress bars are common place in GUIs and…are used for showing many things, from loading…resource progress to experience progress towards the next…level, or how much inventory space has been used.…Progress bars are essentially a visual representation of…two values, a maximum value and a current value.…When the current value equals the maximum value, the progress bar is full.…And when the current value is at zero,…or the minimum value, the progress bar is empty.…Ideally, we'd like to have the bar be…oriented horizontally, or vertically, or maybe even in-between.…
Let's take a look at some code.…Our progress bar is going to take a display…name, size, our min value, max value, and current value.…It's also going to generate textures for itself for the bar-empty, and bar-full.…Since a progress bar is essentially two boxes, one box holds the other.…The outer box is an empty box and the inner box is scaled…to represent the current value relative to the size of the outer box.…
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.
