Unable to Use Animation Presets With Null Object
on Apr 27, 2012 at 1:34:54 am

Hello,

I am trying to apply wiggle-position to a null object, but that does not seem to affect it. As it turns out, no animation presets or expressions like wiggle(1,000) will change anything. Any one know why?

I'm assuming you're applying the expression to the position property.

Wiggle takes multiple parameters or arguments.
You can make it work with the following 2 parameters:
1) frequency
2) amount.

So the expression you quote (wiggle (1,000) means wiggle 1 time per second, zero amount. Its not wiggling any distance.

Here are some references for the expression language:

I am trying to make the null object wiggle randomly. Applying wiggle- position or the expression wiggle(1,000) makes a normal layer wiggle. Yes i want to apply this to the position. Why does it work for normal layers but not null objects?

This will not produce a wiggle since the wiggle amount is 0.

Here is a CS5 file demonstrating that wiggle(1,000) produces no movement on a Solid layer and that wiggle(5,10) produces movement on a Null Object.

Ok, I see, but my main problem is why doesn't the animation preset work with the null objects?

OK I see now.

The preset applies the Transform effect which does not work on Null Objects.

Ok, Thanks. I just need to use an expression like wiggle(5,10) to animate it. Thanks for the help.
