Change default font for all Text etc

How can I define a default font for a project, so that I later easily can change it?
I have included a couple of ttf/otf fonts in the Assets folder and will choose and pick from one of them.

Hello Umai,

To define one font in your whole project you can take a variable of type GUIStyle and variable for font of type Font. For eg:

var myStyle : GUIStyle;
var This_font : Font;

Now In the start() you can assign the font you want to be displayed in the game.

function Start ()
//Here i am assigning the font to GUIStyle
myStyle.font = large_font;
// You can also adjust font size, font color and other properties of font here.
myStyle.normal.textColor = Color.white;

I hope this will help you.
Thank you
