Q: How can I speed the frame rate or slow it down when the movie is
playing? For example, I would like to slow the frame rate from the default of 20 fps to 15 fps from
frame #80 to frame #150. Then frame rate should speed back up to 20 fps after frame #151, (fps =
frames per second).
A: One way is to use
"interval". An example of changing the speed of the movie
from frame #80 to frame #150 is shown below.
Create a key frame at frame #80 and place this script:
var fps:Number = 80;
var intervalID:Number = setInterval(this, "advanceFrame", 1000/fps);
stop();
//
function advanceFrame() {
clearInterval(intervalID);
gotoAndStop(_currentframe+1);
if (_currentframe<151) {
intervalID = setInterval(this, "advanceFrame",
1000/fps);
} else {
play();
}
}
