Unity GUI Tutorial - Scale GUI to the right size for every resolution

Check out the code below the videos
GUITextures

This Unity Tutorial will show you how to make your GUI automatically scale to the right size for every screen resolution and aspect ratio.

To connect your device to unity, download the unity remote app and follow these steps: http://answers.unity3d.com/questions/198853/unity-remote-for-android-not-working-solution.html

Time Breakdown:

1:20 - Overview of different aspect ratios for mobile and desktop

2:00 - Demonstration and explaination of why Pixel Inset values are not good for scalability

3:10 - Explaination of how Pixel Inset values work

5:00 - Use Transform Position and Scale values instead!

7:30 - GUITexture anchor points are in the center by default

7:50 - How to change the anchor point of a GUITexture (useful for health bars and such)

9:45 - Demonstration of why you can't get perfect squares and circles without code

10:10 - Using a script to make a perfect square GUITexture

11:39 - Explaination of how the script works

15:20 - Outro Thanks for watching :D

* Attach this script to a GUITexture or GUIText to fix its scale to the aspect ratio of the current screen
* Change the values of scaleOnRatio1 (units are in % of screenspace if the screen were square, 0f = 0%, 1f = 100%) to change the desired ratio of the GUI
* The ratio is width-based so scaleOnRatio1.x will stay the same, scaleOnRatio1.y will based on the screen ratio
*
* The most common aspect ratio for COMPUTERS is 16:9 followed by 16:10
* Possible aspect ratios for MOBILE are:
* 4:3
* 3:2
* 16:10
* 5:3
* 16:9
