title: How do I set a transparent sprite background in Flash?
body: <p>I'm playing with <a href="http://www.dncompute.com/blog/2007/03/19/seed-based-pseudorandom-number-generator-in-actionscript.html" rel="nofollow noreferrer">this ActionScript</a> which generates a random 'squiggle'.</p>
  
  <p>Each time a 'squiggle' is placed, it appears within a sprite with a white background.</p>
  
  <p>If I change the background colour of the flash file to pink for example, it would still show up as white.</p>
  
  <p>Does anybody know how I might make the sprite background transparent? Thanks.</p>
