Multiple commands not taking effect.
Hey there, I have a dumb question.
I have an animation of a piston with a pressure gauge. When the top of the piston (called “Stopper” in my comp) comes down, I want the needle (simply called “Needle”) to both turn, and wiggle more. My problem is that needle layer seems to only follow one of the expressions, the one that comes first, and ignore the other. The expression doesn’t break either.
I tried throwing sliders onto my needle layer, and tying the wiggle layers to those, then tying the sliders to the Y value of the Stopper, thinking that would somehow work. Same result.
Dumb question, I know. And I can’t just animate it by hand. I’m making this for scientists who have almost zero knowledge of how to use Adobe products. So this stuff needs to be as automated as possible.
Thanks is advance!
thisComp.layer("Stopper").transform.yPosition;
wiggle(effect("Frequency")("Slider"),effect("Amplitude")("Slider")) -

Just found a solution, for anybody who is interested. I just added a “+” between the two lines.
thisComp.layer("Stopper").transform.yPosition + wiggle(effect("Frequency")("Slider"),effect("Amplitude")("Slider")) -
You can’t combine expressions by just stacking them on top of each other. You need to combine the results. In your case it would be something like this (not tested):
y = thisComp.layer(“Stopper”).transform.yPosition;
w = wiggle(effect(“Frequency”)(“Slider”),effect(“Amplitude”)(“Slider”))-value;
[value[0],y] + wDan

Thanks Dan! For the solution and the knowledge!

Cudos to both of you.
Dan for the knowledge, and you Justin for a basic work around that worked for my needs, and as a expression newb was easier to grasp. lol
Great stuff
