Start and stop a wiggle at intervels on same layer

[Guest]

I have a dot that fly's around my comp. When it stops it wiggles and buzzes and then stops wiggling. I need it to move on to the next spot and then wiggle again. Then onto the next spot and repeat. I am able to do this wiggle or buzz once but I don't know how to make it continue at each stopping point. Any help would be great.

Thank you

There are a bunch of ways to do this. This one assumes that the layer stops at each even-numbered keyframe:

dur = 1; // total wiggle duration (sec)
ramp = .1;// time to ramp int0/out of wiggle
freq = 3; // wiggle frequency
amp = 50; // wiggle amplitude;

n = 0;
if (numKeys > 0){
  n = nearestKey(time).index;
    if (key(n).time > time){
      n--;
    }
}

if (n > 0 && (n%2 == 0)){
  t = time - key(n).time
  w = wiggle(freq,amp);
  if (t < ramp){
    linear(t,0,ramp,value,w)
  }else{
    linear(t,dur-ramp,dur,w,value)
  }
}else{
  value
}

Ok this is great if you have any idea how this code stuff works. I don't I am new and I found what I needed for the one time wiggle on the net. I figured out which settings I needed to modify by trail and error, but there is to much here for me to figure out. I am sorry I just don't understand.(
