Hi there,

I would like to insert some blinking / twinkling / flashing (whatever you want to call it!) stars into the background of my flash banner and I’m a little unsure as to how to do it using code (as2) - can anyone help please?!

I would like a total of between 10 and 20 stars to appear randomly in a specific part of the background and I would like the alpha / transparency of each star to fade in and out independently.

I have found the following code which I believe does the job, however I am unable to get it working within my banner. If anyone has a suggestion or could recommend some other code it would be very much appreciated!

Here’s the code I’m trying to get to work…

```auto
