How to insert animation before and after this animation template??

Question

I'm using the file from the online template below, but am going to replace the flag with a man's tie that's going to be "flapping in the wind" momentarily.
BUT I need to add a small amount of animation before this "flapping" animation begins, as well as after it, and I only want the flapping to last about 1.5 seconds or so - not continually looping.

I don't know how to even begin to add the animation I need before/after, and to edit the time down on the looping. Any help is GREATLY appreciated!!

Answer 1

change the flag to your tie and change the onEnterFrame loop:
use
loopI = setInterval(loopF,40);
to start the waving and use:
clearInterval(loopI);
to stop the waving.
function loopF(){
    // move the matrix by speed along x to shift the noise
    shift.translate(speed, 0);
    // drawing in the perlin movie clip,
    // create a rectangle with the perlin noise
    // drawn in it with an offset supplied by the
    // shift matrix
    with (displace_mc.perlin){
        clear();
        beginBitmapFill(noiseBitmap, shift);
        moveTo(0,0);
        lineTo(ramp._width, 0);
        lineTo(ramp._width, ramp._height);
        lineTo(0, ramp._height);
        lineTo(0, 0);
        endFill();
    // draw the displacement movie clip in the
    // displaceBitmap (used in displaceFilter)
    displaceBitmap.draw(displace_mc);
    // apply displaceFilter to the flag
    flag_mc.filters = [displaceFilter];
updateAfterEvent();
