"foreground sprite suddenly reduces"?

I am not sure what you mean.

when a player press a button he will run for a particular time at a faster rate and till that time the progress bar will reduce gradually from say value 1 to 0.75 . 

what i did is sudden change of progressbar from say 1 to 0.75 but this is some thing which I dont want.

I want a code for progressbar which will gradually decrease the progresss bar from a value say 1 to 0.75 in a time "t"...

thanks

NGUI does not provide the functionality that it sounds like you're seeking. This is something you can easily do yourself. Just maintain two values... "realValue" and "displayValue".

Then you'd do something like displayValue = Lerp(displayValue, realValue, t)

And then its up to you do something like t += Time.deltaTime * scaleFactor; each frame, reset t to zero on value change, etc etc

OR ...

You have "Steps" set to something like "4" instead of being "0"
