Well that I am referencing a slider in the outer comp is wanted and should not be a problem. I totally agree about the second problem…

I thought about the valueAtTime option, but could not find anything that works. But I think the startTime could be the missing link :).

I will try and get back here. Thanks for your input.

Ok thank you. I think I’ll do it manually then :).

Oh that’s a nice idea. I think I need to internalize some of those AE expression concepts a little bit.
Thanks mate, for the hint. I’ll try it out.

Oh. I did not know the difference. Thanks for that piece of information :).
I mainly talk about expressions then, because I have never done anything with scripting and I would not even know how to tackle that task.
Anyway, I don’t really understand your proposed solution.
The Null Object would not follow the one path node, I’m interested in, right?
So how would I get the position of one path node? (the toWorld and toComp would just translate a position from layer space to comp space, correct?)

I understand that I can get the position at time X, if I manually place a nullobject above it. But what I really want is to have a layer follow that path node which is animated. So basically I could get it’s initial position from the null object, but after a few frames, my path node has wandered and my null object would remain at it’s place…
Or do I misunderstand you?

Anyway. Your help is incredibly much appreciated, also in other posts where I found a lot of answers to my questions already. Thanks you.

I did actually. That was the first thing I did after the post. I got kind of a working example, but as I was not sure about if my code actually works (no debugging or logging option, except from a text layer output, which I didn’t want to to ;)) I stopped playing around.
So you would say this works, by increasing the amp value?

I also experienced problems with the following: I assume that the expression code is called everyframe. So how I can I increment a variable during my animation?
So
freq = freq + 0.05; Does not work at all.
I thought maybe by not declaring it at the beginning, but this would make my expression fail.

Is my assumption correct?

My only other idea was to link the freq – or the amp – to time.
So I would set something like this:
amp = time * 0.05

So after the first frame I would have time = 1 and amp = 0.05, right?
And after the second time = 2, amp = 0.1.
I hope I understand the time variable correctly…

Any hints related to these things are welcome :).
Thanks in advance.
