  How do I randomly change between six variables every second

  Posted by Jeremy Krzmarzick on April 30, 2020 at 6:19 pm

  seedRandom(Math.floor(time), timeless = true);
c1=thisComp.layer("Null 1").effect("Color Control")("Color");
c2=thisComp.layer("Null 1").effect("Color Control 2")("Color");
c3=thisComp.layer("Null 1").effect("Color Control 3")("Color");
c4=thisComp.layer("Null 1").effect("Color Control 4")("Color");
c5=thisComp.layer("Null 1").effect("Color Control 5")("Color");
c6=thisComp.layer("Null 1").effect("Color Control 6")("Color");

  Something like this should work:

  seedRandom(Math.floor(time), timeless = true);
  c1=thisComp.layer(“Null 1”).effect(“Color Control”)(“Color”);
  c2=thisComp.layer(“Null 1”).effect(“Color Control 2”)(“Color”);
  c3=thisComp.layer(“Null 1”).effect(“Color Control 3”)(“Color”);
  c4=thisComp.layer(“Null 1”).effect(“Color Control 4”)(“Color”);
  c5=thisComp.layer(“Null 1”).effect(“Color Control 5”)(“Color”);
  c6=thisComp.layer(“Null 1”).effect(“Color Control 6”)(“Color”);
  idx = Math.floor(random(6))+1;
  eval(“c” + idx)
