So yah I use to “know” flash about 5 years ago but have since forgot most of everything.
Anyways, here’s the situation: I’ve got 3 layers of snowflakes that fall across the image. All three layers fall at different speeds.
What I’m trying to do is loop the movies so there is always snowflakes falling but the movie just loops when the last layer has finished falling so there’s a period where no snow flakes are falling until the movie starts over.
What you should do is make each layer a separate movie clip symbol. Then, put each movie clip on the first frame. That way they’ll loop once they’re done playing, instead of the whole movie.
The simplest way to do this would be to do the follow for each layer:
Select all of the frames in a layer.
Right-click and select Cut Frames.
Go to Insert > New Symbol
Create the Symbol
Go to the timeline (in the symbol), right-click the first frame and select Paste Frames
Rinse and repeat)
Then on the first frame of your main timeline, you would just drag out an instance of each of the movie clips and stack them on top of each other.
Hope that helps.
(Btw, a LOT has changed in five years, so don’t feel bad if it all feels new, because it almost is.)
