Make a sprite fade out on mouse click

[gameCoder]

Hi,
I have code that already detects a mouse click on a sprite , based on the presence of its collider.

Is there a way I can make a UISprite fade out on mouse click?

I changed the alpha to 0 and that totally made the sprite disappear. No other alpha value seems to have any effect.

Thanks

You have to change the alpha value on time.
The basic way is to change it into an Update function, decrementing it like this:

1. float speed; //speed of fadeoff.
2.  
3. void Update()
4. {
5.     myWidget.alpha -= Time.deltaTime * speed;
6. }
7.  

Maybe it exists a tween function in NGUI that does the job for you, or you can also use a tween plugin (like HOTween) to perform it.
