| One way would be to do it like this: amp = 20; freq = 1; ramp = .5; offset = amp/2; ease(time,inPoint,inPoint+ramp,0,offset + wiggle(freq,amp/2)) If you want to adjust how close to zero it gets, you could tie the offset variable to a slider: amp = 20; freq = 1; ramp = .5; offset = effect("Slider Control")("Slider"); ease(time,inPoint,inPoint+ramp,0,offset + wiggle(freq,amp/2)) You could also do it with Math.abs(), but that will give you some pretty sharp bounces at zero: amp = 20; freq = 1; ramp = .5; ease(time,inPoint,inPoint+ramp,0,Math.abs(wiggle(freq,amp))) Dan -----Original Message----- From: James Culbertson Sent: Wednesday, April 25, 2012 4:01 PM To: After Effects Mail List Subject: [AE] wiggle expression - rotation in one direction? How would I limit a wiggle expression to one direction? For instance, rotation originating at 0 and wiggling in a negative direction, all other wiggle parameters the same.
