  • want a different ‘seed’ out of wiggle expression…

    hi, I am have a wiggle expression that is being controlled by a slider property, I move the the slider up and down and I get a wiggle, but if I move it to the same value the wiggle is exactly the same – not random. Is there anyway to get a random seed?

    I believe that wiggle seeds itself from the layer number. So make a solid, turn off the visibility, place it ABOVE the wiggling layer (which ups the layer number of the wiggle layer by one) and you’ll get a new dance.

    I’m not entirely sure what you are trying to do. I’m assuming you are using the sliders only inside your wiggle(). in this case you would not see much changes because all you do is manipulate amplitude and frequency. You need to add

    seedRandom(>>>your slider<<<); before your wiggle. But beware, just like the normal random the values will change instantanuously, not interpolated. this will look jumpy. If you need smooth transitions, you need to interpolate multiple random sources for which someon provided a code example on this forum I believe. Do a search to find it. Mylenium [Pour Myl
