  Wiggle range whole numbers

  Posted by Jason Jantzen on December 1, 2016 at 12:08 am

  I edited this expression from Dan Ebbert’s random motion post, but can’t figure out how to get whole number values.

  segMin = .1; //minimum segment duration
segMax = .3; //maximum segment duration
minVal = 1;
maxVal = 5;

  end = 0;
j = 0;
while ( time >= end){
j += 1;
seedRandom(j,true);
start = end;
end += random(segMin,segMax);
}
endVal = random(minVal,maxVal);
seedRandom(j-1,true);
dummy=random(); //this is a throw-away value
startVal = random(minVal,maxVal);

  Try this:

  
segMin = .1; //minimum segment duration
segMax = .3; //maximum segment duration
minVal = 1;
maxVal = 5;

  end = 0;
j = 0;
while ( time >= end){
j += 1;
seedRandom(j,true);
start = end;
end += random(segMin,segMax);
}
endVal = Math.floor(random(minVal,maxVal+1));
seedRandom(j-1,true);
dummy=random(); //this is a throw-away value
startVal = Math.floor(random(minVal,maxVal+1));

  Thanks Dan! I tried inserting Math.floor in various places in the expression but I don’t understand the expression enough to modify it like that. This works perfectly 😀
