Triggering random animaton
Hi folks,
I’m trying to get a visual up and running but could use some expression help to save a huge amount of time over the hand animating alternative.
I have a little looping animation of a circle. It starts from a dot and sits there for a while then grows in size before shrinking once again to a dot.
I need to place these dots evenly spaced on a line (and possibly later in a grid) and have them trigger from random frames, so I get a random growing scenario.
So…
1) how to place multiple instances of a comp evenly along a line2) how to place multiple instances of a comp within a grid
3) how to trigger the comp to start from random frames.
thanks so much for all your sage-like advice,
moog

This should give you a basic grid layout:
origin = [25,25]; // upper left corner
horizontalSpacing = 50;
verticalSpacing = 50;
numCols = 10; // number of columns in each row
col = (index-1)%numCols;
row = Math.floor((index-1)/numCols);
[col*horizontalSpacing,row*verticalSpacing]And this time remapping expression should give you a random start:
maxDelay = 5; // max delay in seconds
seedRandom(index,true);
delay = random(maxDelay);
Math.max(time-delay,0)Dan

briiliant, I’ll give that a try,
