  • A blinking expression that gets faster with time

    Posted by Laurence Willmott on April 9, 2013 at 4:14 pm

    Hello,

    I am looking for an expression that will allow a graphic to blink on and off and then get faster as a car approaches in the lane next to ‘my’ car. I’ve found a few expressions but cannot get them to work together.

    Any help would be greatly appreciated.

    Speed/frequency control with expressions is not simple. You should look this over:

    If that doesn’t scare you off, come back with any questions.

    Hi Dan,

    How would you add time offset to your speed control expression? like valueAtTime(time-1) // min one sec for example
    I want to offset the keyframes of spd = effect(“Slider Control”)(“Slider”); based on the index number.
    I’ve tried adding offsets everywhere but it keeps jumping around or rotating backwards really fast…

    Cheers,
    Sander
