Define “dance”. Do you want it to assume a new random spot on the beat or move in a continuous way, from spot to spot with the beat?
If you want to jump in on your own, here is a page on making things happen to the beat:
https://www.motionscript.com/design-guide/audio-trigger.html
He is a series, four pages, on random expressions:
https://www.motionscript.com/mastering-expressions/random-1.html
For the quickest, if you got the “hold time” to match the time of the beats, here are two expressions from that last page that would do the trick:
holdTime = .5; //time to hold each position (seconds)
minVal = [0.1*thisComp.width, 0.1*thisComp.height];
maxVal = [0.9*thisComp.width, 0.9*thisComp.height];seed = Math.floor(time/holdTime);
seedRandom(seed,true);
random(minVal,maxVal)and for continuous movement
segDur = .5;// duration of each “segment” of random motion
minVal = [0.1*thisComp.width, 0.1*thisComp.height];
maxVal = [0.9*thisComp.width, 0.9*thisComp.height];seed = Math.floor(time/segDur);
segStart = seed*segDur;
seedRandom(seed,true);
startVal = random(minVal,maxVal);
seedRandom(seed+1,true);
endVal = random(minVal,maxVal);
ease(time,segStart,segStart + segDur, startVal, endVal); -

April 8, 2008 at 4:08 pmSorry, i should clarify a little bit better………I’m looking to make this logo “hop” around on screen, kinda like a bunny rabbit.
Any thoughts?
