Scaling UI sprite like EXP bar, health bar etc

[matt1]

Hi there,

I am looking to scale many UI elements like Health bar, mana, energy and experience. I've acheived this reletively easy before with Unity's GUI system, however I am a little lost doing it with NGUI.

Originally I done it like:

1. GUI.Box(new Rect(100 ,Screen.height - 100,PercentageCalculator(PlayerExp,ExpToLevel)* Screen.width / 150, 25), "EXP");
2.  
3. public float PercentageCalculator(float x, float y) {
4.                 return(x / y * 100);
5.         }
6.  

However I can't controll the scale with of the UISprite using this method.

Any ideas would be appreciated!

Thanks

If you select your UISprite object, then choose Sprite type : filled, and Fill Dir : horizontal then you can control the fill amount and obtain something similar to what you are asking.
