Question for Dan (or anyone else) about noise()
Hey Dan I was trying to get the noise() function to work today and I cant figure out whats going on:
I used this expression on the source text property of a text layer:
seedRandom( index, true );
amp =effect(“Amp”)(“Slider”);
compress = effect(“Compress”)(“Slider”);
xNoise = amp * noise(position[0] / compress);
yNoise = amp * noise(position[1] / compress);Math.round( xNoise) + ” , ” + Math.round( yNoise ) + ” “;
as long as amp and compress are positive, shouldn’t the noise values xNoise and yNoise be positive? I think so, but for some reason they are coming out negative. Any ideas?

Strangely, noise() returns a value in the range -1 to +1.
