When you publish the movie, the file speedball1.html and speedball1.swf will be created in the same directory as the movie.
Find speedball1.html and open it using a text editor such as notepad or Dreamweaver.
Find two places in the code that say <param name="bgcolor" value="#ccccff" />
Immediately after each of those line add the line below:
<param name="FlashVars" value= "speed=5" />
Save the file, then close it and double click to open the page in the browser. The ball now has a speed of 5 and moves faster.
