Movie clips will loop no matter what, unless there’s a stop() action in the script. So…
When I’ve created a 1 frame movie clip, I always place a stop action in that frame, because I’ve just assumed that flash doesn’t care that it only has one frame, and keeps looping it. I know it does no harm, but I figure reducing loops is never a bad thing.
But I’ve noticed in Open Source files, other movie clips that only have one frame, the author didn’t add a stop command.
Does Flash not loop movie clips with 1 frame (if it has 2 or more it will), or do other people just not consider it?
