GUI Skin
GUISkins are a collection of GUIStyles that can be applied to your GUI. Each Control type has its own Style definition. Skins are intended to allow you to apply style to an entire UI, instead of a single Control by itself.

Details
When you are creating an entire GUI for your game, you will likely need to do a lot of customization for every different Control type. In many different game genres, like real-time strategy or role-playing, there is a need for practically every single Control type.
Because each individual Control uses a particular Style, it does not make sense to create a dozen-plus individual Styles and assign them all manually. GUI Skins take care of this problem for you. By creating a GUI Skin, you have a pre-defined collection of Styles for every individual Control. You then apply the Skin with a single line of code, which eliminates the need to manually specify the Style of each individual Control.
Creating GUISkins
GUISkins are asset files. To create a GUI Skin, select Project View.
from the menubar. This will put a new GUISkin in yourA new GUISkin file in the Project View
Editing GUISkins
After you have created a GUISkin, you can edit all of the Styles it contains in the Inspector. For example, the Text Field Style will be applied to all Text Field Controls.
Editing the Text Field Style in a GUISkin
No matter how many Text Fields you create in your script, they will all use this Style. Of course, you have control over changing the styles of one Text Field over the other if you wish. We'll discuss how that is done next.
Applying GUISkins
To apply a GUISkin to your GUI, you must use a simple script to read and apply the Skin to your Controls.
// Create a public variable where we can assign the GUISkin var customSkin : GUISkin; // Apply the Skin in our OnGUI() function function OnGUI () { GUI.skin = customSkin; // Now create any Controls you like, and they will be displayed with the custom Skin GUILayout.Button ("I am a re-Skinned Button"); // You can change or remove the skin for some Controls but not others GUI.skin = null; // Any Controls created here will use the default Skin and not the custom Skin GUILayout.Button ("This Button uses the default UnityGUI Skin"); }
In some cases you want to have two of the same Control with different Styles. For this, it does not make sense to create a new Skin and re-assign it. Instead, you use one of the Custom Styles in the skin. Provide a Name for the custom Style, and you can use that name as the last argument of the individual Control.
// One of the custom Styles in this Skin has the name "MyCustomControl" var customSkin : GUISkin; function OnGUI () { GUI.skin = customSkin; // We provide the name of the Style we want to use as the last argument of the Control function GUILayout.Button ("I am a custom styled Button", "MyCustomControl"); // We can also ignore the Custom Style, and use the Skin's default Button Style GUILayout.Button ("I am the Skin's Button Style"); }
