Document height

1

Hi all

I’m using the script below to generate snow/fairy dust.

However I need it to begin falling not from the top of the flash file, but about 300px from the top. And the script will vary this slightly which is what I need.

Can someone let me know how to achieve this? I gather it involves reversing where the swf defines the beginning of ‘height’ (bottom as opposed to top) or somesuch…

Cheers
