Well, i was bored again, and here is the outcome: A snow effect for Flash AS 2, which uses very less CPU power.
It is extremely simple to use:
1. Create a new empty movieclip on the top layer of your (root) movie.
2. Move the new movieclip at the x and y position 0 Pixel.
3. Copy the following code to the first frame in your new movieclip: Flash Snow Script
Don’t forget to set your movie’s framerate to 30 FPS!
That’s it, compile and be happy.
There are some parameters you can change on top of the Script, mainly to tweak the number of snowflakes and the CPU usage.
Have fun and Happy Christmas!
