  • Expression to make dozens of objects appear randomly

    Posted by Leigh Dowding on September 30, 2009 at 4:00 pm

    I have been given an illustrator file all on one layer which has dozens of dots that make up a map of the world.

    I want to make each dot appear randomly (over a short space of time) and was wondering if there was an expression that could do this or a faster way?

    An opacity expression like this for each dot should do the trick:

    maxTime = 3; // max time for all dots to appear
    seedRandom(index,true);
    myTime = random(maxTime);
    if (time > myTime) 100 else 0

    I’m very interested to know if the expression Dan gave you solved your problem.
    Can you share the results and perhaps give more detail about how your AI file was set up?

    Thanks
