Random position start from specific position
Hi I’m trying to get some object start to move random from one figure with this expression added to position:
segMin = .3; //minimum segment duration
segMax = .7; //maximum segment duration
minVal = [0.1*thisComp.width, 0.1*thisComp.height];
maxVal = [0.9*thisComp.width, 0.9*thisComp.height];seedRandom(index,true);
segDur = random(segMin, segMax);
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);But the problem is when I add the expression the object position on the first frame now is in random position – can i get it to start from specific position?

Try this one:
minDur = .3;
maxDur = .7;
vMin = [0.1*thisComp.width, 0.1*thisComp.height];
vMax = [0.9*thisComp.width, 0.9*thisComp.height];
seedRandom(index,true);
tNext = tPrev = inPoint;
n = 0;
while (tNext <= time){
tPrev = tNext;
tNext += random(minDur,maxDur);
n++;
}
seedRandom(tPrev,true);
vPrev = (n == 1) ? value : random(vMin,vMax);
seedRandom(tNext,true);
vNext = random(vMin,vMax);
ease(time,tPrev,tNext,vPrev,vNext);
