A blinking expression that gets faster with time
on Apr 9, 2013 at 4:14:29 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.

Laurence

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
